Limited Slip Differential Lsd The Basic Principle - Differential, Type, Use - Auto Repair And
Is a modified car, modified car parts necessary
, LSD seems complex, but in fact works very well understood. About two sets of thermal differential friction plate group to change oil viscosity difference ratio, so that manipulation becomes handy Accelerator And a better sense of direction, more importantly, LSD is the rage, the core part of the drift racing is one. Comparing the characteristics of various types of differential: 1. Open Differential Cherokee open differential structure, is typical of planetary gear set structure, but the sun wheel and the outer ring gear teeth are the same. In this planetary gear set, the initiative is a planetary gear wheel, driven wheel are two sun wheels. Through the planetary gear transmission features we know that if the planetary gear as the driving shaft, two sun wheel speed and direction of rotation is uncertain, even the two sun wheels turning in the opposite direction.
Vehicle straight state, the characteristics of this differential is, to the same two axle torque transfer. In a driving wheel suspension case, if the shaft is uniform rotation, there is no adhesion of the driving wheel drive Power , If the shaft is to accelerate the rotation, there is adhesion of the driving wheel of the driving force is equal to the angular acceleration of the wheel suspension and the product of inertia.
Vehicles turning Tire Not slippery state, connecting the two axle differential torque in the opposite direction, to provide forward drive vehicles, only the inside of the wheels, frame and the inner planets between the sun gear from the other slow-speed transmission into drive, Drive Feeling that corner speed to accelerate more powerful than straight.
The advantages of open differential is driven on paved roads on the switch to the best effect. Drawback is the loss of adhesion in the case of a driving wheel, the other did not drive.
Open differential application of paved roads for all vehicles, drivers and front axle rear axle drive can be installed.
2. Limited slip differential Limited slip differential to make up for part of the open differential defects in the off-road driving, which is the institutional open differential to improve, the differential gear side of the shell to increase friction between the film , corresponds to the planetary gear set is concerned, that is, planets round the sun between the frame and the increase of the friction plate, increasing the sun wheel and the planet frame free turning resistance moment.
Limited slip differential to provide additional torque, and transmission friction disc drive and the speed difference between the two driving wheels.
Open differential in the improvement of the structure produced LSD, can not be 100% of the limited slip, slip coefficient for the higher limit, the worse the vehicle's steering characteristics.
LSD with open differential transmission characteristics and mechanical structure. Advantage is to provide some limited slip torque, cornering performance drawback is the deterioration of friction disc limited lifespan.
LSD is the scope of road pavement and mild off-road. After the drive is typically used. Installed before the drive is generally not as LSD would interfere with steering, limited slip coefficient the greater the shift more difficult.
3. Locking differentials (mechanical lock, electric lock, air lock)
To ensure off-road vehicles in complex traffic driving under the performance of the mechanical structure by a certain differential locked, to achieve synchronization of the two axle rotation. Through the planetary gear set analysis, is the variable speed planetary gear set locked institutions to ensure that between the planet carrier and the sun wheel, and two between the sun gear transmission ratio is 1:1. Can lock the sun gear and planet carrier, can be locked planet carrier and planet gear, you can also lock the two sun wheels.
