Jaw locking type differential mechanism

Abstract

The invention discloses a jaw locking type differential mechanism. The jaw locking type differential mechanism comprises a shell assembly, a left half axle gear, a cross axle, a right half axle gear and end face jaw teeth, wherein the left half axle gear, the cross axle, the right half axle gear and the end face jaw teeth are arranged in the shell assembly, the cross axle is provided with a planetary gear, the end face jaw teeth are slidably connected with the shell assembly, the shell assembly is connected with a locking assembly, the locking assembly is connected with the end face jaw teeth,and the locking assembly can push the end face jaw teeth to move in the direction of the right half axle gear. According to the jaw locking type differential mechanism, the locking assembly can pushthe end face jaw teeth to move in the direction of the right half axle gear, the end face jaw teeth are meshed with the right half axle gear, rigid connection between the right half axle gear and theshell assembly is formed, rotation of internal parts of the differential mechanism is limited, locking of the differential mechanism is achieved, the reliability of the differential mechanism is improved, and the bad road trafficability of a vehicle is greatly improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a claw locking differential. Background technique [0002] A vehicle differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning or driving on an uneven road, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive the four wheels, all the wheels must be connected, if the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving in a curve, in order for the car to drive in a curve The rotation speed is basically the sa...

Problems solved by technology

[0004] An obvious disadvantage of the open differential is that when one side of the wheel loses adhesion, such as one side of the wheel is suspended, the wheel on the suspended side will rotate at twice the speed of the casing, while the opposite side will stand still. The power will be released by the wheel on the suspended side, and the vehicle cannot move forward, reducing the reliability of the differential
