Problems solved by technology

The limit device of the independent suspension is generally designed on the shock absorber. This structure limits the up and down travel of the suspension to a certain extent, and has the disadvantage of inhibiting the ride comfort of the car; and in some models, due to structural requirements, the limit The positioning device needs to be designed on the upper and lower control arms, which will occupy a large design space and increase the complexity of the suspension

Embodiment 1

[0021] The independent suspension damping and limiting device used in this embodiment includes an outer sleeve assembly 3 with a fan leaf 12 and an inner shaft core assembly 4 with an umbrella piece 13, and the inner shaft core assembly 4 is installed outside inside the sleeve assembly 3, and is coaxially connected with the outer sleeve assembly 3; each umbrella piece 13 of the inner shaft core assembly 4 is limitedly set on the two leaves of the outer sleeve assembly 3 12, the space between two fan pages 12 is divided into a first oil chamber 14 and a second oil chamber 15. A damping hole 8 and a one-way valve 9 are arranged on the umbrella piece 13 of the inner shaft assembly 4. The one-way valve 9 is installed in the installation hole of the one-way valve. The cavity 15 is connected, and end caps 5 are respectively fixedly connected to the ends of the outer sleeve assembly 3, and the end caps 5 are used to seal the hydraulic oil in the chamber.

Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 is that the independent suspension damping and limiting device in this embodiment is installed at the joint between the control arm and the sub-frame (or vehicle body), and is the joint between the control arm and the sub-frame (or vehicle body). Body) adapters. Wherein, the control arm is fixedly connected with the outer sleeve assembly 3 , and the sub-frame (or vehicle body) is fixedly connected with the inner shaft core assembly 4 .

[0024] The inner shaft core assembly 4 has 3 umbrella pieces, and the outer sleeve assembly 3 has 3 fan leaves, and the oil cavity between every two fan leaves is divided by an umbrella piece 13 to form 6 oil cavities. Each chamber is filled with hydraulic oil, and the hydraulic oil passes through the sealing element to ensure the tightness of the device. The sealing element mainly includes an elastic element 10 and an oil seal block 11, and the elastic element 10 and the oil seal...

Abstract

The invention relates to damping and limiting devices, in particular to an independent suspension damping and limiting device. The device is installed at the connecting position of a control arm and a vice vehicle frame (or a vehicle body), and the occupied area of the device is small; and each umbrella piece of an inner shaft core assembly is arranged between two fan leaves of an outer sleeve assembly in a limited mode correspondingly, and the effect for controlling the bouncing journey of a suspension can be achieved. Owing to the fact that the device has a damping characteristic, the device further has a suspension damping effect.

Description

technical field [0001] The invention relates to a vibration-reducing and limiting device, in particular to an independent suspension vibration-reducing and limiting device. Background technique [0002] In the design of automobile chassis suspension, the limit device of suspension run-out travel in most models needs to be designed separately. The limit device of the independent suspension is generally designed on the shock absorber. This structure limits the up and down travel of the suspension to a certain extent, and has the disadvantage of inhibiting the ride comfort of the car; and in some models, due to structural requirements, the limit The positioning device needs to be designed on the upper and lower control arms, which will take up a large design space and increase the complexity of the suspension. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an independent suspension damping and...
