Description
Technical field
The present invention relates to automotive engineering neck, particularly relates to a kind of damping differential mechanism based on turbine.
Background technology
Automobile differential can make left and right (or forward and backward) driving wheel realize the mechanism rotated with different rotating speeds.Main by a left side
Right axle shaft gear, two planetary gears and tooth rest composition.Function is when automobile turning travels or travels on uneven road surface,
Make left and right wheels roll with different rotating speeds, i.e. ensure that both sides drive wheel to make PURE ROLLING.Differential mechanism is to adjust left and right
The speed discrepancy of wheel and device.When four-wheel drive, in order to drive four wheels, it is necessary to all of wheel is coupled together, as
Fruit is by mechanically coupled together for four wheels, and automobile cannot rotate with identical speed, in order to enable curve driving when
Allow the basically identical property of automobile curve driving rotary speed, at this moment need to add center differential in order to adjust the rotating speed of front and back wheel
Difference.
Open differential, although left and right wheels can be allowed to rotate with friction speed, but when one of them wheel spin,
Another wheel in good road surface also can not get moment of torsion, and automobile just loses the power of traveling.In this case, differential
Device is inoperative.Two such wheel connects together, and power at least can make automobile obtain traveling for delivery to opposite side wheel
Power, thus extricate oneself from a predicament.This situation exists too in center differential.So, people just develop various samples
Diff-lock.
Different differential mechanisms, the locking mode used is different, the most common ADB, substantially has following several
Kind locking mode: forced locking formula, high friction self-locking formula, castellated, Torsen formula and viscosity manifold type.Forced locking formula differential lock
Being exactly to arrange differential lock, this differential lock simple in construction on common symmetric formula bevel differential, it is easy to manufacture, torque distributes
Ratio is higher.But handle quite inconvenience, it is generally required to stop；If it addition, connect too early or take differential lock too late, that
Will produce series of problems during axle device without differential, torque distribution is immutable；High friction self-locking formula has friction disk type and slide block
The structures such as cam-type.The moment of friction produced when friction disk type is by relatively trackslipping between friction plate makes differential mechanism locking, this
Kind differential lock simple in construction, stable working, most common on car and light-duty vehicle；Slipper cam-type utilize slide block and cam it
Between bigger moment of friction make differential mechanism locking, it can improve to a great extent automobile by performance, but structure
Complexity, processing request is high, and friction member abrasion is relatively big, relatively costly.Both the above height friction self-locking formula ADB can be
The output torque of distribution left and right sides wheel in certain limit, and to access disengaging be all automatically to carry out, and therefore applies the widest
General.
Above-mentioned differential mechanism has manipulation quite inconvenience, it is impossible to the problem being automatically adjusted differential damping force.
