Embodiment Construction

[0012] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] Embodiments of the invention include:

[0014] refer to figure 1 , The differential of the present invention is used for driving the steering axle of the vehicle. When the vehicle accelerates or advances at a constant speed, the planetary gear carrier 13 rotates to drive the vehicle forward. The reaction force is transmitted through the left planetary gear 3, the left worm 4, the central worm gear 6, the right worm 7, and the right planetary gear 8. The left and right worms drive the worm gear inward at the same time. The central planetary wheel 5 makes the central planetary wheel 5 in a driven state at this moment, and does not transmit ...

Abstract

The invention discloses a mechanical limited slip differential supportive of being used for driving a steering axle in the technical field of automobiles. A planet gear pair is used to replace a planet gear in an open differential, slip limiting effect of a worm and gear in the planet gear pair is utilized to realize a slip limiting function of the differential, wheel driving force changes linearly, and no impact force is generated. By the above mode, when a vehicle travels on a slippery road, the slip limiting function can be realized by utilizing self-locking performance of the worm and gear; when the vehicle utilizes an engine for braking, a central gear 6 slips to unload force, a central planet wheel 5 transmits force, and the differential is equivalent to an open differential at this moment, so that influence on a steering function due to locking of the limited slip differential is avoided, and the mechanical limited slip differential can be used for driving the steering axle. When the mechanical limited slip differential is used as a non-steering-axle differential or a central differential, the central planet wheel 5 can be omitted, and the central worm 6 is fixed on a planet gear bracket 13, so that structure is simplified while cost is saved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a limited-slip differential. Background technique [0002] Modern off-road vehicles and high-end cars mostly use all-wheel drive. The differentials include ordinary open mechanical differentials with differential locks, electronic limited-slip differentials, and mechanical self-locking transmissions. The most representative mechanical self-locking transmissions are Eaton locking differential and Torsen limited-slip differential. Ordinary open mechanical differentials plus differential locks are inconvenient to operate. Electronic limited slip differentials are not as reliable as mechanical differentials in harsh environments and have a lag in response. The Eaton differential has a large impact and lags in response when the differential is locked. The limited-slip differential is stable, but cannot be used to drive the steering axle due to its self-locking nature. Contents ...
