怎样开好手动档车（How do I drive a manual car）

怎样开好手动档车（How do I drive a manual car） 怎样开好手动档车(How do I drive a manual car) In Germany, France and other European countries, more than 80% cars are manual, because only manual can bring you real driving pleasure. Including BMW, Mercedes Benz, Audi has a manual version available to really understand the car owners. The domestic auto consumers are not mature, there will be a manual not on the level of this ridiculous idea. In addition, it is important to your first car must be manual, it will benefit you for life, and lay a solid foundation for the driver you really experience the pleasure of driving. (especially love VW manual transmission gearbox, travel short, clear and smooth, with the freely flowing style of writing "to describe is an understatement). More than eight years, for the first time racing My 1.8T bought a month, every day, air conditioning, running less than 6000 kilometers, with an average of 10 liters, this is a very Province car, automatic may charge more, but mainly to see how you open. Since the car began to encounter a professional army old driver Bangdai, really benefited! Now although long apprenticeship, consider actually master said the year of the 15 words: "oil cooperation, blocking, the fast is fast, slow is the slow", these 15 words scriptures seems simple, that did not feel how wonderful, but now looking back, not really what better description than it is more real, if we can really understand, then you can reach a higher realm between fast and slow can ease. Since we met the daily driving road is the road, so I believe that "only meat, no meat in the car." With the words, "brake" steady but also reflect a driver quality standard, the brakes are predictable, otherwise it would be said that let the family size LD discomfort. In addition, in the fast braking moment of the brake pedal slightly loosen will be more stable. "Stop" is to do the car wheel, parking can reflect a person whether the driver is rigorous, said the big German car problem! You may often meet, the parking lot was tight, there are few cars broken down across two parking parked. So this is not a technical problem, the car is completely De, the technology is not good, can it several times. See many heroes said M6 and 307 (of course is not to say that they are not good). Hey, Japanese cars are cheap, automatic, not I love female friend more love with worry. For a girl or a novice, or by automatic, automatic discharging and battery no scooter what difference does not need skills. The French car romantic look good, but really want to say solid and fun to drive, or non Germans (mass) of vehicles. The car is shift VW control is a kind of fun! With the freely flowing style of writing "four words to describe the performance of the VW wave box is an understatement! The maximum point automatic car engine is the worst - "force" as the precise manual control. Automatic car throttle to bother, refueling buzzing, is also unable to accelerate the costs of oil. My experience is that in general conditions (city), hand files than from a row of 2~3 oil (about dizzy, bad really ah)! And the hand gear speed overtaking is very great, the driving pleasure feels like having a fly very fast bunker VW car was too strong! If you open the file open 307 Polaris hand, ah, said wave box is really immeasurably! I will not say more The above sentence is only incidentally, has nothing to do with the theme of this paper, remember these 15 words scriptures can be. Now: often said "shift operation with the oil from the" means "". Split view should be control relationship between the gearbox and the speed of the engine, the clutch control left after incision impact of transmission speed has been in decline, because of the transmission loss from the driving force of the engine after the body inertia driving tire with gear rotation. The accelerator pedal foot control is actually the engine speed control level. Here it is necessary to explain the transmission route of car. The engine mixed gas explosion pushes the piston down by the crankshaft, up and down motion of the piston into circular motion of the crankshaft, the crankshaft circular motion output to the flywheel, flywheel and pressure plate is between the clutch, the clutch plate is the center shaft of the gearbox (input shaft), that is to say the flywheel and pressure plate clutch sandwiched in the middle to transfer power to the gearbox, step on the clutch when the flywheel and pressure plate clamp clutch to separate no engine power output and transmission from. A shaft into the transmission gear group after several transfer to the two axis (output shaft), two transmission shaft to the differential, and then through the transmission gear axle to tire. When the clutch is cut, the body inertia will promote the continuous running of the vehicle, although also in deceleration due to their large mass decrease in tire speed is relatively slow. One end of the crankshaft is if you do not continue to fuel because of its small inertia speed will drop faster. The shift operation is to keep one end of the crankshaft speed in the shift to meet the clutch and gear box speed close to the end. Understand that these two can according to need with the clutch pedal release speed and throttle depth to shift operation ideal, improve comfort but also reduce the abrasion of the clutch. Shift operation is the most simple and effective, fast, fast shift "step on the clutch / shifting / uniform loose clutch, the objective is to minimize a flywheel and a shaft between the speed difference, the smooth shift. This method is easy to do in the upshift and downshift in operation, sometimes the effect is not ideal. Downshift when needed another operation - "empty oil boom". "Boom empty oil" is in the clutch pedal, then deep down on the accelerator pedal let the engine speed increase, and then lift the accelerator pedal and loose the clutch pedal. It aims to improve the speed of crankshaft with transmission speed. Lift pedal is to maintain the clutch engagement in normal driving, if not a little loose car ran out. The deep step is to allow the engine speed as soon as possible to enhance (especially for the electronic throttle engine now). Because the electronic throttle control and vehicle pull accelerator is different, electrically controlled throttle throttle pedal only passed to ECU an accelerated desire to speed up to what extent the specific needs of ECU calculation to determine, so pull throttle lag is more obvious than that with oil in operation should be deeper and faster pedal down expressed a strong desire to accelerate. In reduction gear, because of low reduction ratio than high-grade to big, 2500 turn from five to four gear engine at 3000 rpm will roughly approximate, it needs to shift in action after the completion of "empty oil boom" to enhance the speed of the engine and then release the clutch pedal. For example, in case of shift and then reply Guadang also need to "speed up the oil boom in air" to release the clutch pedal. Most civilian car comfort clutch assembly. The assembly of clutch with long trips, clutch is a process from contact with the clutch to complete compaction, and the buffer spring clutch on the attenuation of impact promotes comfort. So the speed of clutch loose but also consider the buffer process suit, if the scope of loose too fast power output will exceed the buffer spring but not comfortable, loose too slow clutch plate and pressure plate, the flywheel disc friction will increase too long half clutch wear. The speed and speed of the decline was. The higher the speed change gear transmission speed is decreased more quickly, the flywheel end is also faster, but the speed of decline and ends is not proportional to the speed. Therefore, the stall speed section needs to detonation oil in different degrees. A supplement to downshift instructions The downward shift has two purposes: one is to slow down, two is overtaking A. deceleration The first step on the brake, then the clutch, the speed is reduced, because the right foot off the accelerator, so the engine speed also began to decrease. Because when the clutch engine resistance is very small (only a flywheel), Speed decreased slowly, and with the input shaft speed of the brake gear box is on the decline, will enter the new gear input shaft speed will increase (that shift coefficient >1), such as 4 for 3 gear input shaft speed will instantly increase to 1.3 times the original, but because the speed has been reduced, so I won't h-throttle can also be achieved in the new gear input shaft speed (i.e. speed clutch sheet) is very close to the engine flywheel speed equal to or. Overtaking B. This is generally not the brakes, downshift in order to get a big torque (so that the acceleration of change), you should press the clutch with his right foot after foot oil, to achieve a smooth shift. So, downshift when overtaking the boom foot oil, deceleration downshift brakes (no detonation oil) can achieve smooth shifting. The truth is, to achieve a smooth downshifts, whether it is to increase the engine speed through the throttle, or through the brake to reduce the speed of the clutch plate, its purpose is to achieve in the new gear on the flywheel and clutch plate speed consistent. The above is to let you know the truth, but to freely use the situation, also need the driver himself in the actual operation experience and feel. With the formula (only in the actual operation, to judge by the feeling) 1, what is called smooth shift Shift smoothness = shift instantly to acceleration (= new gear speed - gear speed) / clutch plate from contact to complete with time. This value is small, shifting more smoothly (i.e. the passengers feel the change speed shift moment) Considering the speed and the gearbox output shaft speed is linear relationship, namely V=k*R2 (V R2 for speed gearbox output shaft speed), so the shift smoothness can also use the speed of an output shaft of the transmission shift difference to measure the difference is smaller, more smooth shift. The engine speed conversion 2, when shifting Let me first define the gear ratio (i.e. different gear ratios): Gear ratio = driven gear teeth / drive gear shaft speed = input / output shaft speed, the output shaft speed = input shaft speed / gear ratio Assuming that the shift immediately before the original stalls (the original gear tooth ratio N1) under the engine speed is R1, then the gearbox output shaft speed is R = R1/ n1. The clutch pedal, the engine flywheel and clutch plate out. This car is still running at the same speed as the moment (ignoring resistance), due to the transmission output shaft, main reducer between the transmission and differential, transmission gear wheel rigid relationship, constant speed gearbox output shaft speed will remain unchanged. The gearbox starting new gear (new gear gear ratio is N2), then to solve the problem is: the engine in the clutch recombine speed should be adjusted to the number of turns (R2), the new gear speed to an output shaft of the transmission bit maintain the original speed of R? (that is, to achieve a smooth shift) Note: if the friction clutch contact before the engine flywheel engine speed is adjusted to the desired speed, theory of flywheel and clutch plate can not slide friction, which can reduce the abrasion of the clutch plate. According to the gear ratio formula, R = R2 / N2 = R1 / N1, so R2 = R1 * n2/n1. That is to say, when the engine speed adjustment to the speed can be ensured when the output shaft speed clutch with gearbox constant. We do not put the imitation target gear tooth than the original gear / gear ratio is defined as the "speed adjustment factor", as long as remember the speed adjustment coefficient can achieve smooth shifting. Hypothesis 1 to 2 gear shift gear coefficient is 2, up 2 from 1 in the file file when the clutch throttle speed halved again before release the clutch, can experience the most smooth shift. The actual process of driving feeling, whether smooth irregularity, 1 gear change into 2 gear after the moment, will find the engine speed down immediately, specific down to how many, how much depends on the coefficient. The greater the coefficient, the greater the speed variation. 3, example Polaris 1. 8T MQ250 manual transmission gear ratio as follows (MQ200 gear ratio with the same MQ250, other parameters): 1 n1= 33:10 = 3.3 2 n2= 35:18 = 1.944 3 n3= 34:26 = 1.308 4 n4= 35:34 = 1.029 5 n5= 36:43 = 0.837 The calculation speed adjustment coefficient of the adjacent stalls between upshift: (T<1 means upshift proper reduction of oil) 1->2 T12 = n2/n1 = 1.944/3.300 = 0.6 (1 + 2 file file is 0.6 times the speed of oil drop 1 stalls) 2->3 T23 = n3/n2 = 1.308/1.944 = 0.7 (ibid.) 3->4 T34 = n4/n3 = 1.029/1.308 = 0.8 4->5 T45 = n5/n4 = 0.837/1.029 = 0.8 Similarly, can speed adjustment coefficient calculated downshift when (T >1, means a downshift due to oil) 2->1 T21 = n1/n2 = 3.300/1.944 = 1.7 (2 down 1 files to enhance the speed of oil 1.7 times 2 stalls) 3->2 T32 = n2/n3 = 1.944/1.308 = 1.5 (ibid.) 4->3 T43 = n3/n4 = 1.308/1.029 = 1.3 5->4 T54 = n4/n5 = 1.029/0.837 = 1.2 From the above change coefficient can also be seen: a higher gear gear shift more easy to achieve: the most easy to achieve smooth shifting is switching between 5 stalls and 4 stalls, the most difficult is to switch between 2 stalls and 1 stalls.
