Integrated axle hub bearing nut locking device

Abstract

The invention discloses an integrated axle hub bearing nut locking device, and relates to an axle part. The device comprises an axle housing axle tube, a hub bearing and an integrated locking nut assembly, wherein the outer circle of the end portion of the axle housing axle tube is provided with an external thread; the integrated locking nut assembly comprises an elastic washer, an adjusting nut and a limiting ring, one end of the elastic washer is attached to the end face of the hub bearing, the other end of the elastic washer is attached to the adjusting nut, and a plurality of limiting holes are evenly formed in the elastic washer; the adjusting nut is integrally formed by a nut body and an outer edge, and the outer edge is provided with a mounting hole at the position corresponding tothe limiting hole; the limiting ring is connected to the nut body in a sleeving mode, the limiting ring is provided with a limiting hook, and the limiting hook penetrates through the mounting hole inthe outer edge and is connected with the limiting hole of the elastic washer in a matched mode. The device can prolong the service life of the bearing, has the characteristics of simple structure, lowcost, high assembly efficiency, light weight, small occupied space and reduced failure rate, and is easy to popularize and use.

Description

technical field [0001] The invention relates to an axle component, in particular to an integrated axle hub bearing nut locking device. Background technique [0002] At present, the locking structure of automobile axle hub bearing nuts mainly adopts the split structure of slotted nut + washer + fixing screw + spring washer, see Figure 9 , the installation method is to attach the slotted nut 4 to the hub bearing 2 and tighten it to a certain torque, install the washer 5 on the slotted nut 4, and then install the spring washer 6 and the screw 7; pay attention to the washer 5 during installation The hole on the top is aligned with the hole position on the slotted nut 4, and the spring washer 6 and the screw 7 can be loaded onto. This kind of split locking structure has the following disadvantages: (1) The number of parts is large and the cost is high; (2) The slotted nut 4 is directly attached to the outer bearing 3 of the hub, and the bearing is subjected to a large force, whi...
