Split type rear axle structure of mining dump truck

Abstract

The invention discloses a split type rear axle structure of the mining dump truck, which comprises a rear axle housing, a left half axle sleeve and a right half axle sleeve, wherein the sleeve connecting end faces of the left half axle sleeve and the right half axle sleeve are connected to the rear axle housing connecting end faces on the left side and the right side of the rear axle housing through bolts and gaskets respectively; and o-shaped sealing rings are arranged between the attaching end faces of the left half axle sleeve, the right half axle sleeve and the rear axle housing. The splittype structure is used for a rear axle assembly, the maintainability and interchangeability of the rear axle assembly and peripheral components can be effectively improved for a long time, the maintenance operation period is shortened, the production efficiency is improved, and the operation cost is saved.

Description

technical field [0001] The invention relates to a mining dump truck, in particular to a split rear axle structure of the mining dump truck. Background technique [0002] Mining dump trucks are the main transportation equipment for open-pit mines. The equipment has the characteristics of high load and harsh operating conditions. Therefore, the reliability of the structure, the maintainability of the system, and the interchangeability of components are of utmost importance to mining dump trucks. important. [0003] The rear axle assembly is the main component to drive the mining dump truck forward and backward. The rear axle assembly is usually composed of two parts, the rear axle housing and the half shaft casing. The traction A-frame, differential, driving half shaft and rear suspension cylinder are installed on the rear axle housing. The wheel reducer, brake, rear wheel Both are installed on the half-shaft bushing; these parts and the half-shaft bushing are usually wearin...

AI Technical Summary

Problems solved by technology

Such a structure brings a lot of additional work procedures to the maintenance and replacement, resulting in a long maintenance and replacement operation cycle, which seriously affects the production efficiency of the mine

At the same time, the integral welded structure causes only one side of the axle bushing to be damaged, and the entire rear axle assembly is facing scrapping. The maintainability and interchangeability are poor, and it causes a lot of waste, which leads to the maintenance cost of the mine. increase
