Title:
VEHICLE AND AXLE THEREOF, AND DIFFERENTIAL
Document Type and Number:
WIPO Patent Application WO/2021/057949
Kind Code:
A1
Abstract:
A differential (250), a vehicle, and an axle (200). The differential (250) comprises: a driven disc (210), wherein an inner peripheral surface of the driven disc (210) serves as a first contact surface; two half-shaft connectors (221), wherein an outer peripheral surface of each half-shaft connector (221) serves as a second contact surface, and one of the first contact surface and the second contact surface is an annular surface and the other is a polygonal surface; and two groups of engagement devices (230), each group of engagement devices (230) comprising a roller (231), a roller holder (232), a switch driving member (233), a switch driven member (234), and a first elastic reset mechanism (235), wherein the roller (231) has a separation position and an engagement position with respect to the annular surface, the switch driving member (233) selectively drives the switch driven member (234) to move so as to move the roller (231) from the separation position to the engagement position, and the first elastic reset mechanism (235) is used to return the roller (231) from the engagement position to the separation position. The configuration stabilizes the differential (250), and reduces resistance or seizing of gear teeth, thus ensuring vehicle drivability.
