A hinged type self-discharging automobile chassis

Abstract

The invention discloses an articulated dump truck chassis. The front suspension is composed of front U shape frame, vertical telescopic elastic component, front cross tie. The middle of the closing end of the front U shape frame is ball-pivot coupled with the front frame. The two biforked ends of the front U shape frame are respectively connected with the two sides of the front vehicle bridge. Two ends of the elastic component is connected between the top of the two sides of the front vehicle bridge and the bottom of the front frame. The two ends of the transversal front cross tie are respectively pivoted between the front frame of the two sides of the chassis and front vehicle bridge. The back suspension is composed of weigh beam, middle U shape from connected between the middle vehicle bridge and back frame, back U shape from connected between the back vehicle bridge and back frame, middle cross tie and back cross tie. The invention has simple structure, better maneuvering characteristics, and can prevent the frame from torsional deforming. The invention not only ensures the whole rigidity of the articulated dump truck, but also prevents the articulated dump truck from distortional deformation on the rough ground, increases maneuvering characteristics, especially for rough ground.

Description

technical field [0001] The invention relates to the technical field of dump trucks, in particular to an articulated dump truck chassis. Background technique [0002] At present, the chassis of the load dump truck mainly includes the girder, the front axle and the rear axle. The girder is composed of the front and rear frames hinged together. The front and rear suspensions of the existing dump trucks are connected to the vehicle frame through hinged joints. Although the up and down jumps and horizontal swings can be realized, the independent up and down jumps of each wheel cannot be realized, and the swing range of each axle is relatively large. Especially when driving on rough roads, the various additional torsional and bending loads imposed by the axle on the frame are relatively large, which affects the service life of the frame and even the entire vehicle.

AI Technical Summary

Problems solved by technology

The front and rear frames of the girder of the dump truck can only swing on the horizontal plane and cannot rotate around the longitudinal axis of the girder. And increase the extra mechanism, and limit the maneuverability of the dump truck

[0004] In addition, the front suspension of existing dump trucks mostly uses oil-pneumatic springs, but the manufacturing cost of oil-pneumatic springs is high, and a set of special inflation equipment is required for maintenance during use. Regular inflation according to certain operating procedures is troublesome for maintenance. During the working process, due to the deflection of the cylinder axis and poor sealing, the inner surface of the cylinder is easily scratched
