AI Technical Summary

Technical Problem

Existing loader wet drive axles generate heat due to frequent braking under heavy load conditions, leading to increased gear oil temperature. Iron powder circulates through the oil circuit to the cooling system, causing blockages and damage to the oil suction pump.

Method used

Install an oil filter inside the axle housing to ensure that the gear oil is filtered before being sucked out, preventing iron powder from entering the cooling system and protecting the oil suction pump and radiator.

Benefits of technology

It improves oil cleanliness, ensures the normal operation of the cooling system, maintains normal gear oil temperature, improves drive axle reliability, and reduces maintenance costs.

Description

TECHNICAL FIELD

[0001] The utility model relates to engineering machinery loader wet type drive axle technical field, concretely relates to loader wet type drive axle with oil filter. BACKGROUND

[0002] The existing loader wet type drive axle can produce a large amount of heat when frequently braking during heavy load working condition, and the temperature of gear oil in the axle housing is increased, in order to ensure that the temperature of gear oil is normal, the gear oil in the drive axle is extracted, and the gear oil is returned to the axle housing after external heat dissipation, but as the operation of the internal gear, bearing and other components of the drive axle is continuously carried out, a large amount of iron powder is produced, the iron powder is circulated to the heat dissipation system along with the oil circuit, the heat dissipation system is blocked, and the oil suction pump is damaged, and finally the heat dissipation system fails. SUMMARY

[0003] The utility model discloses a kind of loader wet type drive axle with oil filter, which is simple in structure, low in maintenance cost and reliable in use, and solves the problem that the iron powder produced by the internal gear, bearing and other components of the existing loader wet type drive axle during work is circulated to the heat dissipation system along with the oil circuit, causing the heat dissipation system to be blocked and the oil suction pump to be damaged.

[0004] To achieve the above purpose, the loader wet type drive axle with oil filter of the utility model comprises a main drive 1, an oil filter 2 and an axle housing 3; the main drive 1 and the oil filter 2 are installed on the axle housing 3.

[0005] The loader wet type drive axle with oil filter having the above structure has the following technical features and advantages:

[0006] 1. By increasing the oil filter 2 inside the axle housing, the gear oil in the axle housing is filtered when being sucked out, ensuring that the oil reaching the oil suction pump and the radiator is free of iron powder and other foreign matter, solving the problem of damage to the oil suction pump and the radiator due to the presence of iron powder and other foreign matter in the oil in the prior art, greatly improving the cleanliness of the oil and enabling the oil cooling system to work normally, ensuring that the gear oil inside the drive axle remains at a normal working temperature, and ultimately improving the reliability of the drive axle.

[0007] 2. The structure is simple, compact, low in maintenance cost and reliable in quality. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 is the front view structural schematic diagram of the loader wet type drive axle with oil filter of the utility model.

[0009] Figure 2 is Figure 1 the main sectional view structural schematic diagram of the oil filter.

[0010] Reference signs: main drive 1, oil filter 2, axle housing 3. DETAILED DESCRIPTION

[0011] The specific embodiments of the loader wet drive axle with oil filter of the utility model will be further explained in detail below in combination with the drawings.

[0012] Figures 1-2 As shown in the drawings, the loader wet drive axle with oil filter of the utility model comprises a main drive 1, an oil filter 2 and an axle housing 3; the main drive 1 and the oil filter 2 are installed on the axle housing 3.

[0013] The wet drive axle with oil filter of the utility model can greatly improve the oil cleanliness of the oil cooling system when the axle housing internal gear oil is filtered through the oil filter 2 when being sucked out, avoids the damage of the oil suction pump and the radiator due to the foreign matters such as iron powder in the oil in the prior art, ensures the normal operation of the heat dissipation system, keeps the internal gear oil of the drive axle at the normal working temperature, prevents the internal parts of the drive axle from being damaged due to the high gear oil temperature, and finally improves the reliability of the drive axle.
