Description

Technical Field

[0001] The utility model relates to the technical field of vehicle axles, in particular to a vehicle axle with stable braking. Background Art

[0002] A car axle, also known as the axle, is connected to the vehicle frame (or body) via a suspension, with wheels mounted on either end. The axle's function is to bear the vehicle's load and maintain normal driving on the road.

[0003] For example, the patent application CN205365075U discloses a vehicle axle with stable braking, comprising a drive axle housing, axle sleeves, and axles. The axle sleeves are two, each fixedly connected to the drive axle housing and symmetrically arranged. Axles are coaxially disposed within each axle sleeve, connected to the inner wall of the axle sleeve via a rotating member. A 1020 final reducer is mounted within the drive axle housing via a fixing device. Both axles extend into the drive axle housing and are transmission-connected to the axles. This utility model has a simple structure and is easy to use. Installing the 1020 final reducer improves braking performance compared to previous vehicles. Furthermore, the weight of the axle after installation is reduced without compromising overall performance. Furthermore, the assembly cost of the 1020 final reducer is slightly lower than that of the 6470 final reducer, thus reducing the assembly cost of the entire axle.

[0004] However, under long-term braking, the existing axle will cause the axle housing and the wheel shaft to shake due to the inertia of the vehicle, which will make the braking unstable. In severe cases, the axle will be damaged and may cause traffic accidents. Utility Model Content

[0029] Through the above solution, one end of the brake pad can be rotated through the connecting frame, the brake pad can be driven to expand through the hydraulic cylinder, and the brake pad can be quickly driven to rebound after braking through the rebound column.

[0030] In this embodiment, preferably, the rotating mechanism 102 includes a rotating shaft 304 , a mounting plate 305 is fixedly mounted on the front end of the rotating shaft 304 , the mounting plate 305 is movably mounted on the outside of the brake pad 206 , and a mounting screw 306 is fixedly mounted on the front end of the mounting plate 305 .

[0031] Through the above scheme, the mounting plate can be rotated by rotating the shaft, and the mounting plate can be installed on the wheel by installing the screws. By installing the mounting plate on the outside of the brake pad, friction can be generated with the mounting plate to brake when the brake pad is extended.

[0038] When using a vehicle axle with stable braking of this embodiment, the user connects the brake disc 204 through the connecting screw 203 through the connecting rod so that the brake disc 204 and the bridge housing 502 are fixed, and then the reducer 406 is installed through the rear cover 104, and the reducer 406 and the rear cover 104 are fixedly installed through the assembly screw 405.

When the vehicle is driving, the car engine is driven through the transmission The structure drives the transmission shaft 401 to rotate. The rotation of the transmission shaft 401 causes the gears inside the reducer 406 to rotate, thereby causing the rotating shaft 304 to drive the mounting plate 305 and the wheel to rotate, thereby causing the vehicle to move. When the vehicle brakes, the hydraulic cylinder drives one end of the brake pad 206 to expand outward through oil pressure, and causes the other end of the brake pad 206 to rotate on the connecting frame 301. When the brake pad 206 is expanded, it fits and rubs against the inside of the mounting plate 305, causing the mounting plate 305 to drive the wheel to stop, thereby completing braking. After braking, the rebound column 303 drives the brake pad 206 to quickly complete the rebound reset, and the inertia generated by braking is transmitted to the vehicle chassis through the diagonal support rod 105, so that the bridge housing 502 and the rotating shaft 304 will not shake due to inertia, thereby avoiding damage to the axle during braking, thereby making the braking stable.
