1 a drive train
Introduction:
Usually a driveline clutch, transmission, universal transmission, final drive, differential and axle and so on. The basic function of which is emitted by power of the engine to the drive wheels of the vehicle, generating a driving force, so that cars can travel at a certain speed.
For the rear-drive car, the engine torque is sequentially sent through the clutch, gearbox, universal joints, drive shaft, the main reducer, differential, transmitted to the rear wheel axle, so the rear wheel is also known as drive wheels. Get driving wheel torque would give the ground a backward force, and therefore face the driving wheel to produce a forward reaction, this reaction is the driving force of the car. Automotive front wheel drive train and generally do not directly contact the power, so called the driven wheel.
The composition and arrangement of the drive train with different types of engines, the installation location, and automotive applications varies. For example, off-road vehicles with four-wheel drive, then it increases the driveline splitter assembly and the like. As for the front engine front drive vehicle, it is no driveline transmission shaft means.
arranged in the form:
Common mechanical transmission line arrangement pattern position and the pattern primarily with the driving engine of the automobile concerned. May be divided into:
1 rear-drive mdash; FR: i.e. Front engine, rear drive
This is a conventional arrangement pattern. Most trucks at home and abroad, some cars and some buses have adopted this type. .
After two rear drive mdash; RR: i.e. rear engine, rear-drive
With this arrangement multiple pattern on large buses, mini small amount, using this light sedan type. Rear engine, front axle overload is not easy, and can more fully utilize the trunk area, furtherCan effectively reduce the height of the vehicle floor or the full use of space in the middle of the floor placed baggage car, but also help mitigate the effects of heat and noise of the engine to the driver. The disadvantage is that the difference between the engine cooling conditions, certain faults running is not easily perceived by the driver. Remotely operated control mechanism also complicates maintenance adjustments inconvenience. However, due to the advantages of more prominent, more and more on a large bus applications.
3 pre-precursor mdash; FF:. Front engine front-drive
This type of control mechanism is simple, the engine cooling conditions. But the quality of the automobile move uphill, the front drive wheels of reduced mass is attached, the drive wheels slippery; since the vehicle mass forward, the front wheel overload, high speed roll phenomenon tends to take place when going downhill braking. Now most cars take this type of arrangement.
4. The off-road vehicle drive train
is generally off-road vehicle all-wheel drive, front engine, with the transmission in the transmitting power splitter to all the wheels. Currently, light off-road vehicle commonly used 4times; 4 drive types and medium-sized off-road vehicles using 4times; 4 or 6times; 6 Drive model; heavy-duty off-road vehicles generally use 6times; 6 or 8times; 8 drive type.
