Adjustable pump valve self-locking antiskid differential

Abstract

The invention provides an adjustable pump valve self-locking antiskid differential which is mainly composed of a differential shell, a gear pump, a bidirectional throttling valve and left and right semi-shaft gear rings. Two gear shafts of the gear pump respectively extend out of a driving gear lefttwards and rightwards to be meshed with the left and right semi-shaft gear rings of wheel semi-shafts; rotating speed difference of the left and right semi-shaft gear rings relative to the gear pump drives a gear shaft of the gear pump to automatically rotate to pump oil; when oil flow exceeds flow allowed to pass and set by the throttling valve, the throttling valve automatically closes and locks the gear shaft of the gear pump to disable continuous rotating so as to lock the left and right semi-shaft gear rings to rotate synchronously with the gear pump to stop a wheel on one side from sliding and idling and to drive a trapped wheel. By the adjustable pump valve self-locking antiskid differential, when the wheel on one side slides and idles, the left and right wheel semi-shafts can be quickly and automatically locked to synchronous running and can be automatically unlocked after a vehicle travels normally. The adjustable pump valve self-locking antiskid differential has the advantages of simple structure, low manufacturing and maintaining cost, adjustability in speed difference for triggering locking and large output torque.

Description

technical field [0001] The invention relates to a differential, in particular to an adjustable differential which can be automatically locked to prevent wheel slipping and can be automatically unlocked. Background technique [0002] The conventional cross-shaft differential used in ordinary vehicles has an obvious defect of "differential speed without torque" in its design and structural principle, that is, when one side of the driving wheel slips and spins, the other side of the driving wheel The lack of power resulted in the vehicle bogging down. In order to overcome this defect, various improvements have been made to the differential, and various anti-skid locking mechanisms have been installed. At present, there are mainly friction plate locking methods, worm gear locking methods, and viscous coupling locking methods. , but there are still the following disadvantages: the structure and parts are complex in shape, the production and maintenance costs are high, some actio...

[0002] The conventional cross-shaft differential used in ordinary vehicles has an obvious defect of "differential speed without torque" in its design and structural principle, that is, when one side of the driving wheel slips and spins, the other side of the driving wheel Loss of power, causing the vehicle to bog down

In order to overcome this defect, various improvements have been made to the differential, and various anti-skid locking mechanisms have been installed. At present, there are mainly friction plate locking methods, worm gear locking methods, and viscous coupling locking methods. , but there are still the following disadvantages: the structure and parts are complex in shape, the production and maintenance costs are high, some actions and responses are slow, the trigger speed difference is difficult to adjust, or after the load is too large, the friction contact parts are easy to wear, slip, and power distribution Insufficient, resulting in unsatisfactory range of adaptation and cost of use
