Rear steel plate spring for truck

Abstract

The invention discloses a rear steel plate spring for a truck. The rear steel plate spring comprises a steel plate spring body. The steel plate spring body comprises a cross beam, an intelligent system, a first steel plate, a second steel plate, a third steel plate, a fourth steel plate, a fifth steel plate and a sixth steel plate. The intelligent system comprises an infrared inductor, a temperature sensor, a control box, an intelligent processor, a control switch, a power supply device, a power control valve, an oil injection control valve and an overload warning indicator. The first steel plate, the second steel plate, the third steel plate, the fourth steel plate, the fifth steel plate and the sixth steel plate are sequentially stacked from bottom to top, wrapping lugs are welded to the two ends of the fifth steel plate, winding lugs are welded to the two ends of the sixth steel plate, fixed frames are mounted on the two sides of the third steel plate, and first threaded holes are formed in the two sides of the fixed frames in a cut manner. According to the rear steel plate spring for the truck, heat generated by friction between two plates can be reduced through first heat dissipation holes and second heat dissipation holes, the situation that the strength of a spring steel plate is reduced due to the fact that the temperature is too high due to friction is avoided, and therefore the physical heat dissipation function of the spring steel plate is realized.

Description

technical field [0001] The invention relates to the technical field of leaf springs, in particular to a rear leaf spring for a truck. Background technique [0002] There are deficiencies in the rear leaf springs used for trucks in the past. When the trucks drive for a long time, the tires will exert force on the leaf springs due to the unevenness of the road surface. While the leaf springs deform and absorb shock, they also produce friction and release heat. Excessive heat The high temperature leads to the reduction of the strength of the leaf spring, thereby reducing the life of the leaf spring. In addition, the residual dust, mud and rain on the road surface are easy to cause impact and corrosion on the spring steel plate, and accelerate the loss of the durability of the spring steel plate. [0003] Therefore, how to design a rear leaf spring for a truck has become a problem to be solved at present. Contents of the invention [0004] Aiming at the deficiencies in the pr...
