Abstract

The invention belongs to the technical field of differential mechanisms, and discloses an asymmetric self-locking differential mechanism. The asymmetric self-locking differential mechanism comprises adifferential mechanism shell, a first half axle gear and a second half axle gear; two opposite output shaft barrels are arranged on the differential mechanism shell; a helical gear is arranged outside the differential mechanism shell; the first half axle gear and the second half axle gear are both arranged in the differential mechanism shell, and are corresponding to the two output shaft barrels;the pitch radius of the first half axle gear is two times of the pitch radius of the second half axle gear; the asymmetric self-locking differential mechanism further comprises a first planetary gearand a second planetary gear; the second planetary gear is rotatably arranged in the differential mechanism shell, and is engaged with the second half axle gear; and the first planetary gear is rotatably arranged in the differential mechanism shell, and is engaged with the second planetary gear and the first half axle gear.

Description

technical field [0001] The invention relates to the technical field of differentials, in particular to an asymmetrical self-locking differential. Background technique [0002] In multi-axle chassis, differentials are divided into self-locking anti-skid differentials and forced locking differentials. Among them, the self-locking anti-skid differential has the characteristics of sensitive response and stable transmission, and is suitable for use on off-road vehicle chassis to improve its passability. Existing multi-axle vehicles conventionally adopt a symmetric differential with a constant torque of 1:1, or a differential with a constant torque of 2:1. However, according to actual use, due to the design of the internal structure of the existing differential, the self-locking performance is not ideal, and the adjustment range of the torque output ratio is also small. Contents of the invention [0003] The invention provides an asymmetrical self-locking differential, which i...
