Centrifugal Limited Speed ​​Differential

Abstract

The invention discloses a centrifugal speed limiting differential mechanism, and belongs to the technical field of automobile differential mechanisms. A planet gear shaft is divided into two sections. The two sections of planet gear shaft are supported and installed at the upper end and the lower end of a planet wheel through conical roller bearings respectively and extend in an inner cavity wall of an outer shell. A lock sleeve and a centrifugal fly weight device are arranged at the two close ends of the two sections of planet gear shaft respectively. A part abutting against the centrifugal fly weight device is arranged on the outer side of the lock sleeve. An engaging fluted disc is arranged on the two close ends of two spline half shafts. A matching structure matched with the lock sleeve is arranged on the outer side of the engaging fluted disc. According to the centrifugal speed limiting differential mechanism, the rotating speed difference of the left half shaft and the right half shaft can be automatically inducted, and the speed limiting differential function is achieved. Centrifugal fly weight type automatic induction is achieved, the structure is simple, and functions are liable. Separation and union of the differential fluted disc is achieved through the friction function, reliable jointing under the high rotating speed is achieved, and meanwhile destructive impact is avoided. The wedge self-locking type engaging fluted disc is adopted, and a certain self-locking function is achieved after jointing.

Description

Technical field [0001] The invention belongs to the technical field of automobile differentials, and is particularly related to a centrifugal speed-limiting differential. Background technique [0002] The 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 spline half shafts, 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...
