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.
