Heavy-duty vehicle shock absorber

Abstract

A shock-absorbing mechanism of a load-carrying vehicle comprises a frame, the frame is provided with a main transverse shaft, two sides of the frame are provided with main suspension mechanisms, and each main suspension mechanism comprises a swing plate spring, a support plate spring and a connecting structure. The connecting structure is arranged at the front side of the main transverse shaft, the support plate spring is mounted on the main transverse shaft and connected with the connecting structure. The front portion of the frame is connected with the connecting structure through the swing plate spring, and the swing plate spring is hinged to the frame. A main axle is mounted between connecting structures of two main suspension mechanisms. Connecting structures in the shock-absorbing mechanism of the load-carrying vehicle are mounted between two plate springs, so the two plate springs can support the main axle on the connecting structures, the bearing capacity can be raised, the scope of movement of main wheels mounted to the main axle can be enlarged during buffer, and the cross-country performance of a vehicle can be raised. The swing plate springs can swing because the swing plate springs are hinged to the frame, the lifting range of the connecting structures can be further increased, the scope of movement of main wheels is further enlarged, and the cross-country performance of the vehicle can be further raised.

Description

technical field [0001] The invention relates to the field of automobile suspension, in particular to a load-carrying vehicle shock-absorbing mechanism. Background technique [0002] In mountainous areas, when construction needs to be carried out on the mountain, it is necessary to transport construction materials such as cement, sand, and stones to the construction site on the mountain, and transport the construction waste generated by the construction site on the mountain. Due to the steepness of the mountain road, it is almost impossible for general load-carrying vehicles to climb up the mountain through the mountain road. Special vehicles need to be used to climb the mountain for transportation, and there are often steps on the mountain road that special vehicles cannot climb, making the existing transportation vehicles completely unable to carry out transportation work. , can only be carried by hand, the labor cost is high, the labor intensity is high, and the transporta...

Problems solved by technology

Due to the steepness of the mountain road, it is almost impossible for ordinary trucks to climb up the mountain through the mountain road. Special vehicles are needed to climb the mountain for transportation, and there are often steps on the mountain road that special vehicles cannot climb, making the existing transportation vehicles completely unable to carry out transportation work. , can only be carried by hand, the labor cost is high, the labor intensity is high, and the transportation speed is slow, which seriously affects the speed of construction on the site
