Problems solved by technology

But the ordinary conical planetary gear differential will significantly reduce the passability of the vehicle. The reason is that the output torque of the transfer box is distributed to each drive wheel or drive axle according to the transmission ratio of the differential. When one of the wheels or axle adhesion coefficient Smaller, when slipping occurs, the adhesion of the wheel or axle decreases, the driving force decreases accordingly, and the driving force of other axles or axles also decreases proportionally, resulting in reduced vehicle passability

Abstract

The invention relates to a negative pressure angle conical working tooth surface differential lock. A slidable joint sleeve and a stationary joint sleeve are connected together via the joint between an end surface tooth of the slidable joint sleeve formed on the end surface of the slidable joint sleeve and an end surface tooth of the stationary joint sleeve formed on the end surface of the stationary joint sleeve. The slidable joint sleeve is provided with an end surface tooth of the slidable joint sleeve and a slidable joint sleeve body; the tooth top surface and tooth groove surface of the end surface tooth of the slidable joint sleeve are parallel to each other in the axial section and are higher outside and lower inside; the acute angel between the tooth top surface and the tooth groove surface and a rotation axis is beta; a bore of the slidable joint sleeve body is an internal spline of the slidable joint sleeve; the stationary joint sleeve is provided with an end surface tooth of the stationary joint sleeve and an integrally-formed stationary joint sleeve body; the tooth top surface and tooth groove surface of the end surface tooth of the slidable joint sleeve are parallel to each other in the axial section and are lower outside and higher inside; the acute angel between the tooth top surface and the tooth groove surface and a rotation axis is also beta; and a bore of the stationary joint sleeve body is an internal spline of the stationary joint sleeve. In the invention, slide wheels or axles are temporarily and rigidly stopped so as to improve the cross-country capability.

Description

technical field [0001] The invention relates to a planetary gear differential in vehicle transmission. In particular, it relates to a negative pressure angle conical working tooth surface differential lock capable of temporarily rigidly locking a slipping wheel or an axle to improve the cross-country passing ability of the vehicle. Background technique [0002] Off-road vehicles often drive on bad roads or roadless areas. In order to improve passability, multi-axle drives are generally used. The drive axles are equipped with inter-wheel and inter-axle conical planetary gear differentials. But the ordinary conical planetary gear differential will significantly reduce the passability of the vehicle. The reason is that the output torque of the transfer box is distributed to each drive wheel or drive axle according to the transmission ratio of the differential. When one of the wheels or axle adhesion coefficient Smaller, when slipping occurs, the adhesion of the wheel or axle ...
