Embodiment Construction

[0017] figure 1 Among them, the outer cylinder 1 and the inner cylinder 3 are used as the framework of the whole mechanism, mainly used for supporting and assembling with other parts, and the rubber layer 2 plays the role of damping and buffering. The outer cylinder 1 is used as an outer skeleton for matching with the front suspension hole, and a boss 4 is designed on it to limit the installation direction; the inner cylinder 3 is an inner skeleton for installing a composite bushing. The space between the outer cylinder 1 and the inner cylinder 3 is filled with rubber and vulcanized to form a whole. The main bearing direction (up and down direction), the thickness of the rubber filled between the inner and outer cylinders is different, that is, the axes of the inner and outer cylinders do not coincide, and there is a certain eccentric design. On the rubber layer 2, there are two opposite process holes 5, which are distributed on both sides of the axis of the outer cylinder a...

Abstract

A front suspension damping mechanism for a vehicle cab comprises an outer drum, rubber and an inner drum; the rubber is filled between the inner and outer drums, and is integrated with the inner and outer drums by vulcanization and pasting; the axes of the inner and outer drums are not coincided; the outer drum is used for matching with a front suspension hole; the inner drum is used for assembling a composite bush; the rubber plays the functions of damping and buffering; two oppositely arranged process holes parallel with the axes of the inner and outer drums are formed in the rubber layer, and are positioned in a section vertical to the axes of the inner and outer drums; and the profiles of the process holes are in arc transition so as to improve the stress dispersing capacity of a product and eliminate the local stress concentration phenomenon after bearing. The shape of the profiles of the process holes is set according to the rigidity value in the main bearing direction (the vertical direction), so the damping and buffering properties of the mechanism are improved, and the service life is prolonged. The front suspension damping mechanism for the vehicle cab has excellent damping, sound isolating and buffering properties.

Description

technical field [0001] The invention relates to a front suspension vibration damping mechanism of an automobile cab. Background technique [0002] With the development of the economy and the acceleration of urbanization, the demand of users to purchase light trucks has gradually shifted to models that can carry goods but also be beautiful, stylish, comfortable, safe and luxurious. Due to the unreasonable design of the front suspension damping mechanism used in some trucks at this stage, the vibration damping performance of the mechanism is not good, so the vibration and noise generated by the engine cannot be well controlled, so that it is directly transmitted to the car body, affecting the handling of the car Stability and smoothness will make the driver feel uncomfortable and tired, and even damage the auto parts and shorten the service life of the car. Contents of the invention [0003] The object of the present invention is to provide a front suspension vibration damp...
