Connecting assembly of mine self-discharging vehicle front suspension frame guide mechanism and vehicle frame

Abstract

The invention discloses a mine self-discharging vehicle front suspension frame guide mechanism and a connecting assembly of a vehicle frame. The guide mechanism comprises an A-shaped arm. The invention is characterized in that an A-shaped arm installing seat is arranged in the vehicle frame, the A-shaped arm is respectively provided with installing holes corresponding to both ends of the A-shapedarm installing seat, joint bearings are respectively arranged in the installing holes, the installing holes and the A-shaped arm installing seat are respectively connected through connecting shafts, one end of the connecting shafts is matched with the inner rings of the joint bearings, the other end of the connecting shafts is provided with eccentric convex plate, eccentric grooves matched with the eccentric convex plate are arranged on the inner side of the A-shaped arm installing seat, the center of the connecting shaft is provided with a screw hole, and an installing screw is in arrangement matched with the screw hole. The invention is provided with the connecting shafts, the A-shaped arm and the vehicle frame are connected through the connecting shafts, screw bolts are arranged in inner holes of the connecting shafts for limiting the axial movement of the connecting shafts, the eccentric structures limit the relative rotation of the connecting shafts and the installing holes, the abrasion generated by the connecting shafts because of the movement can be prevented, and in addition, the coaxiality requirement during the installation can be met.

Description

technical field [0001] The invention relates to a connection structure, in particular to a connection assembly of a front suspension and a vehicle frame of a mining dump truck. Background technique [0002] The guiding mechanism of the vehicle suspension is a connection device that ensures the reliable transmission of all forces and moments between the wheels or the body and determines the displacement characteristics of the wheels relative to the frame or body. The positions of the front and rear roll centers and pitch centers greatly affect the handling stability and anti-pitch ability of the vehicle. [0003] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. According to different driving modes, it is also divided into 6×4, 8×4 and semi-trailer dump trucks. According to different uses, it is also divided into ① mine dump truck, used to transport coal mines and sand; ② sanitation and green dump tru...

AI Technical Summary

Problems solved by technology

However, with the above connection structure, it is necessary to weld the hinged seat of the pin shaft on the frame and consider the installation arrangement of the lug plate, which requires a large layout space, and the lug plate that restricts the axial movement and rotation of the pin shaft is easily deformed and warped. First, when the mine dump truck is driving on a bumpy road, the pin shaft wears seriously and causes the pin shaft to move axially. precise concentricity
