Automatic anti-slip tooth-embedded cone gear differential mechanism

Abstract

The invention provides an automatic anti-slip tooth-embed cone gear differential mechanism, belonging to the technical field of a gear differential mechanism. The differential mechanism is structurally characterized in that a left semi-shaft and a right semi-shaft of a vehicle are arranged on the same horizontal line through a bearing hole on a shell, and are respectively connected with a left semi-shaft gear and a right semi-shaft gear as well as a left clutch and a right clutch through a spline on a shaft end step; the left semi-shaft gear and the right semi-shaft gear are connected with a left driven locking device and a right driven locking device though a spline of a semi-shaft gear cylinder body; the circumference in a universal joint pin ring body is provided with a driving lockingdevice; a guide hole on the driving locking device is internally provided with a guide pillar; the inner circle of the driving locking device is provided with a center ring; the center ring is meshedwith the left clutch and the right clutch through a tooth-shaped gear; and the driving locking device is respectively meshed with the left driven locking device and the right driven locking device through a ladder-shaped gear, wherein delta 2 is larger than delta 1, delta 4 is larger than delta 2-delta 1+delta 3, the delta 1 is the gap of the gear sides between the driving locking device and the driven locking device, the delta 2 and the delta 3 are the gap of the gear sides on the left clutch and the right clutch and the meshed length of a tooth-shaped inclined surface, and the delta 4 is the gap of the gear side of the spline which is used for connecting the left semi-shaft and the right semi-shaft with the left clutch and the right clutch in a gearing way.

Description

technical field [0001] The invention belongs to the technical field of gear differentials, and in particular relates to a jaw-type automatic anti-skid bevel gear differential. Background technique [0002] At present, there are several types of anti-skid differentials used in vehicles: ①Forcible locking differentials, the switching between the locking and differential states is achieved by manual operation, generally when parking. The operation will bring adverse consequences due to improper operation; ② Jaw type free wheel differential, it is when the vehicle is in a normal steering state and the left and right wheels rotate at a differential speed, or when a wheel on one side slips in the mud, All the power will be transmitted to the slow side wheels, but no power will be transmitted to the fast side wheels, causing the left and right wheels to transmit torque intermittently, which will intensify tire wear; ③Friction plate self-locking differential, its locking torque It ...
