Connecting structure of swinging arm and front axle and mining dump truck

Abstract

The invention discloses a connecting structure of a swinging arm and a front axle. The connecting structure comprises the front axle, a front axle flange plate, a knuckle bearing, a pin shaft baffle and an A-shaped arm, wherein the knuckle bearing is installed inside the front axle flange plate, the bearing baffle is arranged on the outer circle of the knuckle bearing, the A-shaped arm and the knuckle bearing are connected into a whole through a pin shaft, the middle of the pin shaft baffle is connected with the small end of the pin shaft through a bolt, the exterior of the pin shaft baffle is attached to the upper portion of the inner circle of the knuckle bearing, the large end of the pin shaft is attached to the outer portion of the A-shaped arm, the large circle portion of the bearing baffle is connected with the upper end of the front axle flange plate through a bolt, and the middle of the front axle flange plate is connected with the front axle through a bolt. According to the connecting structure of the swinging arm and the front axle, due to the fact that the knuckle bearing is installed on the front axle flange plate, the connecting structure of the swinging arm and the front axle becomes smaller, the structural size of the A-shaped arm is smaller, the connecting structure is simple, compact and practical, and the arrangement space in a front axle system is reduced; the length of a moment arm, connected with the front axle, of the A-shaped arm is reduced, the bearing capacity is greatly enhanced, and the stress situation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of a mining dump truck, in particular to a connection structure between a swing arm and a front axle and a mining dump truck. Background technique [0002] Mining dump truck is a large-scale transportation equipment specially used in large-scale mines (coal mines, iron ore, gold mines, etc.), large-scale water conservancy projects and energy fields. Development plays an important role. As an important part of the mining dump truck, the front axle bears the longitudinal force, lateral force, and vertical load on the vehicle, and realizes the functions of vehicle steering, buffering impact, and attenuating vibration. The front axle of mining dump truck is mainly composed of front suspension cylinder, swing arm, front axle and steering mechanism. As an important part of the front axle, the swing arm has three hinge points in total, and two mounting holes at one end are respectively hinged with the frame. , on...
