Problems solved by technology

However, in the application environment of the chassis swing arm system, simple pure rubber bushes cannot meet the requirements of providing high stiffness and high damping for vibration and noise reduction under low frequency and large amplitude conditions. It cannot meet the vibration and noise reduction requirements of providing low stiffness and small damping

Embodiment Construction

[0022] Such as Figure 1 to Figure 3 as shown, figure 1 It is a structural schematic diagram of a chassis swing arm hydraulic bushing device proposed by the present invention, figure 2 for figure 1 Schematic diagram of the structure of the barrel holder, image 3 for figure 1 Schematic diagram of the structure of the bushing components.

[0023] refer to Figure 1 to Figure 3 , the present invention proposes a chassis swing arm hydraulic bushing device, comprising: a mounting bracket 1, a core barrel 2, a rubber main spring 3, a barrel frame 4 and a limit frame 5;

[0024] Two windows W are symmetrically arranged in the middle of the barrel holder 4, and the unfolded shape of the window W is a rectangle. Cover part; in the bushing part, the rubber main spring 3 is wrapped on the outer periphery of the core tube 2, and the rubber main spring 3 extends outward from the middle of the core tube 2 to form a rib frame and passes through two windows to cover the tube frame 4,...

Abstract

The invention discloses a chassis swing arm hydraulic bushing device and a chassis swing arm system. The chassis swing arm hydraulic bushing device comprises a mounting support, a core tube, a rubber main spring, a tube rack and a limiting rack. The core tube, the rubber main spring and the tube rack are vulcanized to be integrally turned into a bushing component. The limiting rack is mounted between the core tube and the tube rack from the two ends of the bushing component and enables the bushing component to be assembled in the mounting support. Two working cavities are defined between the rubber main spring and the mounting support, the two working cavities are communicated through a flow pass, and a flow discharge sealing rib is arranged in the flow pass. Under the low frequency and large amplitude working condition and the high frequency and small amplitude working condition, the damping characteristic which meets the requirement can be generated through the hydraulic bushing device, and thus the vibration and noise reduction requirement of the chassis swing arm system is met; the chassis swing arm hydraulic bushing device is reasonable in structural design, outer framework assembling of a traditional bushing is reduced, and cost is lowered. Meanwhile, the hydraulic bushing device is easy to assemble on a chassis swing arm, good in connecting reliability and high in working stability.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and noise reduction of a chassis swing arm, in particular to a chassis swing arm hydraulic bushing device and a chassis swing arm system using the chassis swing arm hydraulic bushing device. Background technique [0002] The chassis damping system is a part of the vibration of the whole vehicle, and it has a great influence on the vibration of the vehicle body and the noise level in the cabin. Cars run on various road surfaces, and the chassis plays a vital role due to vibration excitation caused by uneven road surfaces. The quality of the chassis damping system directly affects people's riding comfort. [0003] At present, in the swing arm bushing system, the pure rubber bush has the advantages of low price, good rigidity adjustability, simple manufacturing process, and small space occupation. It is very popular in the automobile chassis shock absorption system. However, in the appl...
