CN219035187U - Wet-type drive axle oil cylinder of loader - Google Patents

Abstract

The utility model discloses a wet drive axle oil cylinder of a loader, which comprises an oil cylinder body; the outer circle of the oil cylinder body is uniformly and densely provided with a plurality of oil cylinder heat dissipation grooves along the circumferential direction so as to increase the heat dissipation area of the oil cylinder body. The utility model has simple and compact structure and long service life, and solves the problems of the prior art that the internal friction plate is fatigued and the friction plate is abnormally worn due to the fact that the heat is increased when the brake is operated frequently under heavy working conditions because the heat radiating structure is not arranged on the outer cylindrical surface of the oil cylinder.

Description

Wet-type drive axle oil cylinder of loader

Technical Field

The utility model relates to the technical field of loader drive axles, in particular to a wet drive axle oil cylinder of a loader, and particularly relates to a wet drive axle oil cylinder of a loader applied to heavy working conditions.

Background

Along with the continuous standardization of underground mining operation, in order to obtain mine safety certification and improve safety, all existing loaders for underground mining working conditions adopt wet drive axles, and the outer cylindrical surface of an oil cylinder of the existing wet drive axles is generally free of heat dissipation grooves and is not provided with other heat dissipation structures. The wet drive axle oil cylinder of the loader has the following defects: because the heat dissipation structure is not arranged on the cylindrical surface of the outer circle of the oil cylinder, the surface area of the oil cylinder is smaller, and when the heavy working condition operation brakes frequently, a large amount of heat generated by the friction plate of the wet brake assembly cannot be rapidly dissipated, so that the performance of the internal friction plate gradually decreases along with the increase of the heat, and finally, the brake is soft and the friction plate is abnormally worn.

Disclosure of Invention

The utility model aims to provide a wet-type drive axle oil cylinder of a loader, which has a simple and compact structure and a long service life, and solves the problems that an external cylindrical surface of the oil cylinder is not provided with a heat dissipation structure, and an internal friction plate is fatigued in braking and abnormal abrasion of the friction plate caused by rising of heat when heavy working conditions are frequent in braking in the prior art.

In order to achieve the above object, the wet drive axle cylinder of the loader of the utility model comprises a cylinder body 2; a plurality of oil cylinder heat dissipation grooves 1 are uniformly and densely distributed on the outer circle of the oil cylinder body 2 along the circumferential direction so as to increase the heat dissipation area of the oil cylinder body 2.

The wet-type drive axle oil cylinder of the loader with the structure has the following technical characteristics and beneficial effects that a circle of heat dissipation groove is additionally arranged on the outer circle of the oil cylinder:

1. through a plurality of hydro-cylinder heat dissipation grooves of evenly densely distributed along the circumferencial direction at hydro-cylinder excircle, make when heavy operating mode brake more frequent, the friction disc of wet brake assembly produces a large amount of heat accessible hydro-cylinder heat dissipation groove 1 and dispels the heat fast, avoids inside oil temperature too high, ensures that the friction disc performance is stable to avoid causing the trouble that the brake is tired soft, friction disc abnormal wear, finally improve the transaxle reliability.

2. Simple and compact structure, long service life and convenient popularization.

Reference numerals: the oil cylinder heat dissipation groove 1 and the oil cylinder body 2.

Detailed Description

The wet drive axle cylinder of the loader is further described in detail below with reference to the accompanying drawings and specific examples.

As shown in fig. 1, the wet drive axle oil cylinder of the loader comprises an oil cylinder body 2; a plurality of oil cylinder heat dissipation grooves 1 are uniformly and densely distributed on the outer circle of the oil cylinder body 2 along the circumferential direction so as to increase the heat dissipation area of the oil cylinder body 2. When the heavy working condition brakes are frequent, a large amount of heat generated by the friction plate of the wet brake assembly can be rapidly radiated through the oil cylinder radiating groove 1, so that the excessive high internal oil temperature is avoided, the stable performance of the friction plate is ensured, the faults of brake fatigue and abnormal abrasion of the friction plate are avoided, and finally the reliability of the drive axle is improved.
