A ball cage differential

Abstract

The invention provides a birfield differential mechanism, and belongs to the technical field of automobiles. The differential mechanism comprises a left short shaft, a right short shaft, a left transmission bevel gear, a right transmission bevel gear, a first planetary bevel gear, a second planetary bevel gear, a first planetary shaft, a second planetary shaft, a differential mechanism shell and adriving gear ring; the inner end of a first sliding rod is fixedly provided with a first locking plate; a second locking plate is fixedly arranged at the inner end of a second sliding rod; a plurality of armature blocks are embedded in the second locking plate, a conductive coil is wound on each armature block, a magnetic ring is embedded in the first locking plate, the conductive coils can cut the magnetic field of magnetic rings so as to form current; and after the conductive coils are electrified, the armature blocks can attract the magnetic rings. The birfield differential mechanism has the advantages of being capable of passively realizing locking of the differential mechanism and the like.

Description

Technical field[0001]The invention belongs to the technical field of automobiles and relates to a ball cage differential.Background technique[0002]The automobile differential can make the left and right (or front and rear) driving wheels realize a mechanism that rotates at different speeds. It is mainly composed of left and right half 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 uneven roads, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the difference in the rotational speed of 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, the car cannot rotate at the same speed when driving in a curve, in order to allow the car to travel in a curve. The rotation speed is basically consisten...

Problems solved by technology

[0004] However, if the differential is equipped with a locking mechanism, not only the internal structure of the differential is complicated, but also the production cost is greatly increased, and the locking mechanism needs to be manually controlled or judged by a computer program to realize the opening or closing of the locking mechanism. However, in many cases, due to the existence of the differential, the loss of torque on one side of the vehicle will affect the safety of the vehicle, such as the inability to pass the slippery road quickly, causing the vehicle to fall into a quagmire, etc., and also affect the service life of the vehicle. Influences, such as severe one-sided skid wear on the vehicle, severe one-side skid on the uneven wear of the brake pads on both sides of the vehicle, etc.
