Problems solved by technology

However, the flexibility of the harder shock absorber is poor, and it is easy to cause the displacement of the spring tray when the vehicle is collided or strongly bumped, reducing the shock absorption effect of the shock absorber, and even making the shock absorber invalid
In severe cold regions, the mechanical properties of spring pallets will be reduced at lower temperatures

Abstract

A low-temperature-resistant spring tray and a preparation method thereof are provided. That low-temperature-resistant spring tray comprises a tray body, a tray body is circular, and a through hole isarranged in the center of the tray body. A mounting sleeve is connected to the through hole; One end of the reinforcing rib is connected with the tray body, and the other end of the reinforcing rib isconnected with the through hole; Damping springs, wherein a plurality of the damping springs are provided, and the damping springs are sleeved on the reinforcing ribs; The waste heat recovery devicecomprises a collecting cover, a conveying pipe and a negative pressure fan, wherein the negative pressure fan is arranged in the conveying pipe, one end of the conveying pipe is connected with the collecting cover, the other end of the conveying pipe faces the tray body, and the collecting cover is used for sleeving on the automobile exhaust pipe. The low-temperature-resistant spring tray has an anti-collision effect and ensures normal use of the spring tray in the event of a strong bumping or collision of the vehicle.

Description

technical field [0001] The invention belongs to the field of automobile shock absorption, and more specifically relates to a low-temperature-resistant spring tray and a preparation method thereof. Background technique [0002] Shock absorber, the shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. In the process of refitting the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the springs is closely related to the weight of the car. Therefore, heavier cars generally use harder sh...
