Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a loader wet drive axle assembly, in particular to a loader wet drive axle oil cylinder. Background Art
[0002] With the continuous standardization of underground mining operations, loaders in underground mining conditions all use wet drive axles with mine safety certification to improve safety. A common wet drive axle for underground loaders in the prior art has a structure with a small cavity in the oil cylinder and a relatively small oil storage capacity. The loader wet drive axle cylinder with this structure has the following disadvantages: Under heavy working conditions, when braking is frequent, the friction plate of the wet brake assembly will generate a lot of heat. Due to the small cavity in the oil cylinder, the oil storage capacity is small, and the oil temperature will rise significantly in a short period of time. The performance of the internal friction plate gradually decreases as the oil temperature rises, eventually causing brake fatigue and abnormal wear of the friction plate. Summary of the invention
[0003] The purpose of the utility model is to solve the above defects and provide a loader wet drive axle oil cylinder with simple structure, low manufacturing and maintenance costs, long service life of the friction plate of the wet brake assembly, and safe and reliable operation. It solves the problem of brake weakness and abnormal wear of the friction plate due to the small oil storage volume in the oil cylinder cavity under heavy working conditions.
[0004] To achieve the above purpose, the utility model provides a loader wet drive axle cylinder comprising a cylinder body 1; the inner cavity of the cylinder body 1 is provided with a left cylinder oil storage tank 2, a lower cylinder oil storage tank 3 and a right cylinder oil storage tank 4, which are respectively located to the left, below and right of the inner cavity of the cylinder body.
[0005] The loader wet drive axle oil cylinder of the above structure has the following technical features and beneficial effects through optimized design and adding an oil storage tank in the inner cavity of the oil cylinder:
[0006] 1. When braking frequently under heavy working conditions, the friction plate of the wet brake assembly generates a lot of heat. By adding an oil storage tank in the inner cavity of the oil cylinder, the oil storage capacity in the oil cylinder can be greatly increased, the internal oil temperature will not rise too quickly, the friction plate performance is stable, and the brake fatigue and abnormal wear of the friction plate are avoided, which ultimately improves the reliability of the drive axle and solves the problem of the prior art that the brake fatigue and abnormal wear of the friction plate are easily caused by the small oil storage capacity due to the small cavity in the oil cylinder under heavy working conditions.
[0007] 2. The structure is simple, the manufacturing and maintenance costs are low, the friction plate of the wet brake assembly has a long service life, and the operation is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 As shown, the utility model is a loader wet drive axle cylinder comprising a cylinder body 1; the inner cavity of the cylinder body 1 is provided with a left cylinder oil storage tank 2, a lower cylinder oil storage tank 3 and a right cylinder oil storage tank 4, which are respectively located to the left, below and right of the inner cavity of the cylinder body.
[0012] When braking is frequent under heavy working conditions, the friction plate of the wet brake assembly generates a lot of heat.
