Abstract

The utility model relates to a swing arm bush structure based on performance optimization belongs to automotive suspension swing arm technical field. Including swing arm, preceding bush and back bush fix respectively in the swing arm, preceding bush be solid construction, the X direction and the Y direction rigidity of preceding bush are the same, the Y direction of back bush be real new construction, the X direction of back bush adopts hollow structure. The utility model has the advantages that: the impact transmitted from the wheels to the vehicle body can be reduced to a great extent, thereby improving the riding comfort of passengers. And simultaneously, the rigidity in the horizontal direction is properly reduced, so that the noise generated when the tire rolls can be reduced.

Description

Swing arm bushing structure based on performance optimization

Technical Field

The utility model relates to a swing arm bush structure based on performance optimization belongs to automotive suspension swing arm technical field.

Background

The automobile suspension swing arm is used for connecting a brake and an automobile body, and wheels are installed on the brake. The swing arm maintains the correct wheel alignment angle during suspension operation and transfers forces and moments between the wheel and the vehicle body. Because the rigidity of the swing arm bushing in different directions has different influences on the performance of the whole vehicle, the performance of the swing arm bushing in each direction needs to be designed respectively.

The front and rear bushings of the swing arm mounted in the prior design are solid structures with high rigidity, so that the front and rear impacts generated when a vehicle passes through a bank or a pit are large, passengers in the vehicle can feel obvious impact and influence riding comfort, and the comfort is improved by improving the bushing structures.

Disclosure of Invention

In order to overcome the weak point of above-mentioned prior art, the utility model provides a swing arm bush structure based on performance optimization improves the travelling comfort through improving the bush structure.

The utility model discloses a realize through following technical scheme: the utility model provides a swing arm bush structure based on performance optimization which characterized in that: including swing arm, preceding bush and back bush fix respectively in the swing arm, preceding bush be solid construction, the X direction and the Y direction rigidity of preceding bush are the same, the Y direction of back bush be real new construction, the X direction of back bush adopts hollow structure.

The X direction of the rear bushing is of an arc-shaped hollow structure.

The diameter of the opening at the two ends of the arc-shaped hollow structure in the X direction of the rear bushing is larger than the width of the arc-shaped hollow structure.

The utility model has the advantages that: the impact transmitted from the wheels to the vehicle body can be reduced to a great extent, thereby improving the riding comfort of passengers. And simultaneously, the rigidity in the horizontal direction is properly reduced, so that the noise generated when the tire rolls can be reduced.

Detailed Description

A swing arm bush structure based on performance optimization as shown in figures 1 to 6 is characterized in that: including swing arm 1, preceding bush 2 and back bush 3 fix respectively on swing arm 1, preceding bush 2 be solid construction, the X direction and the Y direction rigidity of preceding bush 2 are the same, the Y direction of back bush 3 for real new construction, the X direction of back bush 3 adopts hollow structure.

The X direction of the rear bushing 3 adopts an arc hollow structure 31.

The diameter of the two end openings 32 of the arc-shaped hollow structure 31 in the X direction of the rear bushing 3 is larger than the width of the arc-shaped hollow structure 31.

The rigidity of the rear bushing 3 in the X direction, i.e., the horizontal direction, is properly reduced, and when the vehicle is disturbed or impacted in the front-rear direction in the forward running process, as shown in fig. 7, the swing arm rotates around the center of the front bushing 2 with high rigidity, the rear bushing 3 is compressed in the horizontal direction, and the wheel moves backwards for a certain distance, so that the impact transmitted to the vehicle body by the wheel can be greatly reduced, and the riding comfort of passengers is improved. And simultaneously, the rigidity in the horizontal direction is properly reduced, so that the noise generated when the tire rolls can be reduced.
