Problems solved by technology

However, during the driving process of the vehicle, the shaft vibration will enter the resonance mode more frequently. The existing support only isolates the transmission shaft and the frame, and cannot effectively attenuate the vibration of the shaft. The rubber part is prone to fatigue damage or excessive load damage

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0027] Such as figure 1 and figure 2 As shown, the transmission shaft support assembly for a vehicle in this embodiment includes a bearing 1 and an elastic body 2 sleeved on the bearing 1. The elastic body 2 is provided with a damping chamber 21. The damping chamber 21 is an annular chamber. The cavity 21 is filled with viscous silicone oil 24 . In the present invention, a damping chamber 21 is provided on the elastic body 2, and the damping chamber 21 is filled with viscous silicone oil 24, so that the bearing 1 not only has the function of supporting and isolating vibration when the transmission shaft vibrates, but also can reduce vibration through viscous damping, which breaks through The traditional pure rubber support has small damping and is not adjusta...

Abstract

The invention provides a transmission shaft bearing assembly for a vehicle. The transmission shaft bearing assembly for the vehicle comprise a bearing and an elastic body arranged on the bearing in asleeving way, wherein a damping cavity is formed in the elastic body; sticky silicon oil is injected into the damping cavity. The transmission shaft bearing assembly for the vehicle has the advantagesthat the vibration reduction and isolation effects are good; the service life is long.

Description

technical field [0001] The invention relates to the field of transmission shaft support, in particular to a vehicle transmission shaft support assembly. Background technique [0002] When the transmission shaft of an automobile rotates at high speed, it will vibrate violently due to the centrifugal force. When the transmission shaft is too long, its natural frequency will decrease and resonance is easy to occur. Therefore, in order to increase the critical speed of the transmission shaft and reduce vibration and noise, usually the The transmission shaft is divided into two sections, and an intermediate support is added to play the role of supporting and positioning the transmission shaft. The intermediate support is usually installed on the frame beam or the underframe of the vehicle body to compensate for the installation error of the transmission shaft in the axial and angular directions and the driving of the vehicle. The displacement caused by engine movement or frame de...
