Suspension structure

Abstract

The invention belongs to the technical field of automobile parts, and provides a suspension structure, which comprises an outer skeleton and a suspension bracket, wherein the outer skeleton comprises a chassis bracket and a sleeve, wherein the chassis bracket is connected with a chassis, and is connected with the outer wall of the sleeve, and the chassis bracket and a mounting surface of the chassis are parallel to the axis of the sleeve; a bushing is inserted into the sleeve; the sleeve is fixedly connected with the bushing; a center hole is formed in the bushing, and the outer skeleton penetrates through the center hole and a through hole of the suspension bracket through a bolt, and is connected to the suspension bracket. The suspension structure has the advantages that the bolt is only needed to penetrate through the center hole of the bushing and then is connected with the suspension bracket, so the number of connected parts is fewer, and the number of force along each direction and torque of each part in the buffer and vibration reduction actions is reduced; the loosening of the bolt is prevented; the effective tightening torque is guaranteed; the effective buffer and vibration reduction functions are realized, and the operation stability, smoothness and NVH (noise, vibration and harshness) property of an automobile are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile components, and in particular relates to a suspension structure. Background technique [0002] With the popularity of automobile consumption, consumers pay more and more attention to the driving comfort of automobiles, especially cars, and automobile manufacturers have also raised comfort to a very important position. Vibration is also an important factor affecting the comfort of consumers. The suspension structure carrying the powertrain is an important vibration isolation and damping component in auto parts. [0003] Existing suspension structures such as Figure 1-Figure 3 As shown, the outer frame 102 is in the shape of a few characters, and the aluminum core 106, the bushing rubber 103 and the outer bushing 104 are vulcanized into one to form a bush, which is inserted into the outer frame 102 through the diameter reduction process and fastened to the outer frame ;In order to avoid the col...

Problems solved by technology

[0004] Due to the several-shaped structure of the exoskeleton 102 in the existing suspension structure, the screw 109 needs to pass through the suspension bracket 101, the rubber stopper 108, the loose piece rubber 110, and the loose piece 107 at the same time, and then be screwed to the aluminum core 106, and the intermediate parts More, when the engine and the frame vibrate, each component will generate force and moment in all directions when it acts as a vibration damper, causing the screws 109 to loosen easily, and the tightening torque is reduced, resulting in the suspension structure not being effective. Buffering and damping effects affect the handling stability, ride comfort and NVH (Noise, Vibration, Harshness, noise, vibration and comfort) performance of the automobile; meanwhile, the existing suspension structure vehicle frame and suspension bracket 101 are all installed on the The axial direction of the outer frame 102 makes the axial space requirement of the outer frame 102 larger, the assembly space is smaller, it is difficult to assemble, and it is easy to cause interference with other components
