Problems solved by technology

However, the structure of the existing differential is unstable, the performance of adjusting the torque is poor, and a larger proportion of the torque cannot be transmitted to the outer wheel, resulting in poor adhesion. For this reason, a limited slip differential assembly is proposed

Abstract

The invention discloses a limited slip differential assembly. The limited slip differential assembly comprises a double-sided gear and two groups of semi-differential devices which are symmetrically arranged with respect to the two sides of the double-sided gear, wherein each semi-differential device comprises a central collar, a central tooth, a collar, a tooth surface unit, a spring, a spring leaf ring, a friction plate, a gasket, a half-axle gear and a wing gasket; the two collars are connected with the central teeth in a clamped manner through the central collars; and the two collars are embedded into inner slots of the tooth surface units. According to the limited slip differential assembly disclosed by the invention, the structure is simple, two groups of semi-differential devices are symmetrically arranged at the two sides of the double-sided gear, the springs are arranged at the two sides of the double-sided gear, the tooth surface units are engaged with the central teeth or are separated from the central teeth under action of the two springs, so that reasonable distribution of twisting force at the two sides of a drive wheel is realized when a vehicle turns; under a common condition, 95% of twisting force can be transmitted to an outside wheel, namely a wheel with better adhesion force, so that performances of the differential are improved, and therefore, the vehicle has better safety stability performances while turning.

Description

technical field [0001] The invention relates to the technical field of differentials, in particular to a limited-slip differential assembly. 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 basi...
