Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a bracket for installing a bearing of a vehicle transmission shaft. Background Art

[0002] The main drive shaft of a front-mounted commercial vehicle is generally in the form of two or three sections. Each section of the drive shaft is connected by a universal joint and fixed to the frame crossbeam or the body chassis through an intermediate support device. The intermediate support can compensate for the installation error of the drive shaft and has the function of adapting to the engine movement caused by the suspension during driving, the body bumps caused by insufficient ground excitation due to suspension attenuation, and the displacement caused by frame deformation. At the same time, the rubber vibration damping pad in the intermediate support has the function of absorbing the vibration of the drive shaft, reducing noise and bearing radial force.

[0003] In order to solve the problems of poor versatility and high cost of the transmission shaft support device in the related art, a vehicle and a transmission shaft intermediate support device and a mounting bracket (CN205651969U) are proposed. When the inclination angle of the transmission shaft is different, the angle of the intermediate support assembly on the mounting bracket can be adjusted to adapt to different transmission shaft inclination angles, and there is no need to re-manufacture the connecting bracket, which improves the versatility of the transmission shaft support device and reduces the cost.

[0004] Although the above-mentioned vehicle drive shaft support device in this embodiment can achieve different installation angles of the intermediate support assembly to adapt to different drive shaft inclination angles, the arc plate of the protective belt and the transverse plate of the mounting bracket are fixed with bolts, and the mounting bracket does not need to be re-manufactured, which improves the versatility of the drive shaft support device and reduces costs. At the same time, it also avoids the occurrence of the intermediate support and the drive shaft axis after assembly due to component manufacturing errors and assembly errors. The intermediate support can be placed in a free initial working state, reducing the early failure of the drive shaft intermediate support, increasing the service life of the intermediate support, and ensuring the good vibration reduction function of the intermediate support, thereby improving the ride comfort of the entire vehicle; it can be seen that during high-speed driving, the transverse plate rotates with the arc surface to complete the installation at different angles, but during installation, the connection part is too heavy and not firmly fixed, which will cause the vehicle drive shaft and the vehicle connection part to become unstable during driving, resulting in the vehicle being unable to drive normally and causing danger.
