Intermediate support assembly of heavy vehicle drive shaft

Abstract

The invention relates to an intermediate support assembly of a heavy vehicle drive shaft. A bearing is assembled in an inner frame through clamp springs on two sides, sealing rings are arranged on two sides of the bearing, the inner frame is externally vulcanized with an outer cover into a whole through a rubber damping pad, the rubber damping pad is hollowed out internally to form an 'n'-shaped damping groove I which forms a semi-surrounded structure, the rubber damping pad on the upper portion of the inner frame and the inner frame are both covered in an 'n'-shaped empty space, clearances are formed at two side edges of the inner frame, and the lower portion of the rubber damping pad and the inner bottom of the outer cover are connected to form a connecting rib. After the assembly is subjected to complete vehicle trial assembly, the 'n'-shaped semi-surrounded structure of the rubber damping pad can absorb large axial movement of the intermediate support assembly, the angle of the intermediate support assembly is radially adjustable, the radial direction of the intermediate support assembly is ensured to be perpendicular to the axial direction of a center line of the drive shaft, and the intermediate support assembly is simple and feasible and remarkable in benefit, and has promotional value in the automobile industry.

Description

technical field [0001] The invention relates to a transmission part of an automobile, in particular to an intermediate support assembly of a heavy-duty vehicle transmission shaft. Background technique [0002] Now the entire commercial vehicle market is developing in the direction of high precision and high speed. The transmission shaft assembly, as an assembly that transmits power, is connected between the gearbox and the rear axle, and must reliably transmit torque under high-speed rotation. In the design of the whole car, in order to avoid resonance and reduce noise, the transmission shaft is divided into multiple sections. The intermediate support assembly is assembled on the intermediate transmission shaft and the support assembly. It is installed on the vehicle frame and should be able to compensate for the installation error of the transmission shaft and adapt to the displacement caused by the movement of the elastically mounted engine and the deformation of the vehic...

AI Technical Summary

Problems solved by technology

Disadvantages: 1) The rigidity is high, the vibration absorption effect is not good, and the whole vehicle is prone to vibration; 2) When the long-term axial slippage is large, it is easy to tear

Disadvantages: 1) When assembling the drive shaft assembly of heavy-duty vehicles, the strength is slightly insufficient and there is tearing; 2) During long-term axial slippage, the strength between ribs is insufficient; 3) Due to the complex structure , the rubber production process is poor, and it is easy to produce hidden defects of rubber during production

[0010] The above-mentioned patented products cannot eliminate the cumulative error of the radial angle during the assembly process of the vehicle frame, the drive shaft assembly and the assembly process. Some of the axial errors cannot be eliminated, or other adverse consequences will occur after the elimination, resulting in unnecessary Trouble
