Plate spring spring-eye rubber and plastic lining for truck

Abstract

The invention discloses a plate spring spring-eye rubber and plastic lining for a truck. The plate spring spring-eye rubber and plastic lining comprises a cylindrical rubber shaft sleeve and a wear-resisting plastic lining, wherein the rubber shaft sleeve is arranged at the outer side of the plastic lining in a sleeved manner; the diameter of the plastic lining is greater than that of the rubber shaft sleeve; and the rubber shaft sleeve and the plastic lining are assembled into a rubber and plastic lining with damping and wear-resisting effects. The plate spring spring-eye rubber and plastic lining is simple in structure, is reasonable in design, achieves the effects of reducing metal friction and damping in a plate spring system of the truck, can effectively reduce abrasion of a lifting eye bearing and a bearing base; the self-lubricating spring-eye lining does not need extra operation cost of an oil supply device, so that the maintenance is reduced while the design and the mechanical structure are simplified; the service life of the plate spring spring-tye rubber and plastic lining is prolonged, environmental pollution is facilitated, and the carrying capacity and the reliability of a shaft sleeve are improved. Moreover, ozone resistance, pulse type impact resistance and fatigue performance of a product are improved, so that the claim expense of a client is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rubber chemical industry, in particular to a leaf spring lug rubber and plastic bushing for trucks. Background technique [0002] Automotive leaf spring lug rubber and plastic bushings, especially the leaf spring lug bushes used in trucks, are indispensable vibration damping and buffering parts. During its use, especially when walking on a bumpy road after loading, the lug bush is bearing the extrusion force, deformation and wear from different directions. Many car owners often use the lug bush for 2000 kilometers. Extrusion failure and damage lead to abnormal creaking noises in the chassis of the vehicle body during driving, and the effects of vibration reduction and cushioning also fail. In the prior art, a leaf spring for a vehicle is usually provided with a bimetallic bush, and the bush is fitted on the ear hole seat of the leaf spring so as to achieve wear resistance and impact resistance. The bush...
