Embodiment

[0025] Example: such as figure 1 As shown, a locking mechanism for a four-wheel drive differential of an automobile includes a differential case 1 and a planetary gear 2, a plurality of slots 3 are evenly distributed in the differential case 1, and the planetary gear 2 is connected with the slots 3 The corresponding part is connected with a ratchet 5 through the rotating shaft 4, and a return spring 6 is connected between the ratchet 5 and the planetary gear 2, and the ratchet 5 and the card slot 3 are detachably matched.

[0026] The centrifugal force generated by the rotation of the planetary gear 2 drives the tail end of the pawl 5 installed on the planetary gear 2 to move to the position of the slot 3, and the tail end of the pawl 5 is pushed against the slot 3 to realize the locking of the differential. The specific working process As follows: when one side of the wheel-7 slips and loses adhesion, the power is output along the half shaft on the side where the adhesion is...

Abstract

The invention provides a mechanism capable of automatically locking a differential in emergency, and discloses an automobile four-wheel drive differential locking mechanism in order to overcome the defects of poor emergency capacity, locking lag and proneness to operational error due to the fact that a differential locking mechanism in the prior art needs to be controlled manually. The differential locking mechanism is rapid in response and capable of achieving auto-completion and avoiding errors, and comprises a differential shell and a planetary gear; a plurality of clamping grooves are evenly distributed in the differential shell; pawls are connected to positions, corresponding to the clamping grooves, on the planetary gear; a return spring is connected between each pawl and the planetary gear; and the pawls match with the clamping grooves separably. The locking mechanism can be applied to various automobile differentials, and has the advantages of automatic locking, rapid response and capability of avoiding manual operational errors.

Description

technical field [0001] The invention belongs to the technical field of differentials of automobiles, and in particular relates to a differential locking mechanism. Background technique [0002] The traditional car differential is an open type without a locking device. If one wheel slips, the vehicle will lose power. Cause the vehicle to have no ability to get out of trouble under bad road conditions. [0003] The existing locking mechanisms of automobile differentials are generally controlled manually. This structure has the disadvantages of poor emergency response capability, lag in locking action and easy operation errors. [0004] For example, Chinese Patent No. 201120346788.3, ​​a utility model patent titled "Automatically Controllable Differential Locking Mechanism", discloses a differential locking mechanism, in which a lock sleeve is set on one of the half shafts, and the lock sleeve and the planetary The gear frame is provided with meshing parts that can mesh with ...
