Wheel edge deceleration device monitoring system for bulldozer and control method

Abstract

The invention discloses a wheel edge deceleration device monitoring system control method for a bulldozer. The wheel edge deceleration device monitoring system control method for the bulldozer comprises the steps that rotating speed data of a left motor and a right motor are received; the real-time temperature of temperature measuring positions of a left wheel edge deceleration device and a rightwheel edge deceleration device is received, and alarm information is generated if the real-time temperature of any temperature measuring position is not within a preset temperature range; if the real-time temperature of the temperature measuring positions is within the preset temperature range, if rotating speeds of the left motor and the right motor are within a same rotating speed range, judgingis carried out according to a temperature difference value of the real-time temperature of the same position corresponding to the left and right wheel edge deceleration devices; if the rotating speeds of the left motor and the right motor are not within the same rotating speed range, or if any rotating speed of the left motor and the right motors changes, a temperature rise value at any temperature measuring position is received. The wheel edge deceleration device monitoring system control method for the bulldozer is used for monitoring the relevant temperature data of the wheel edge deceleration device in the working process of the full hydraulic bulldozer, so that faults are found in time, and the normal work of the bulldozer is ensured.

Description

Technical field [0001] The invention relates to the technical field of bulldozers, in particular to a monitoring system and a control method of a wheel-side reduction device for bulldozers. Background technique [0002] In recent years, the share of full hydraulic bulldozers in the domestic market has gradually increased. However, due to the unique structure and principle of the full hydraulic bulldozer, it is quite different from the conventional bulldozer, especially the wheel-side reduction gear. High input speed, high speed ratio, and high torque are its notable features. Once the wheel-side deceleration device fails, it will not only cause the loss of the entire wheel-side deceleration system, but also cause damage to the hydraulic system such as the walking motor. [0003] When the brake leaks, the brake cannot be opened and closed normally, and the friction plate is not completely separated, which causes the brake temperature to be too high, which may cause the friction pla...

AI Technical Summary

Problems solved by technology

Once the wheel side reduction device fails, it will not only cause the loss of the entire wheel side reduction system, but also cause damage to the hydraulic system such as the travel motor

[0003] When the brake leaks, the brake cannot be opened and closed normally, and the friction lining is not completely separated, resulting in excessive temperature of the brake, which may cause friction lining sintering and brake damage

When the hydraulic oil escapes into the wheel-side deceleration system, the pressure in the brake housing of the two-stage planetary transmission rises, and the back pressure reversely impacts the oil seal at the motor shaft end, resulting in failure of the oil seal, damage to the traveling system, and a sharp rise in temperature, which affects bearings and seals. At the same time, foreign matter, copper scraps, etc. enter the transmission parts such as bearings and gears, causing damage to bearings and gears

[0004] When the initial oil level is too high or low, resulting in too fast temperature rise or insufficient lubrication, especially at high speed, it is easy to cause seal failure, poor lubrication, friction plate sintering and other faults

Due to assembly and other reasons, the friction plate and light plate are not completely separated or the friction plate is stuck, resulting in damage to the brake

Due to the small adjustment clearance of the bearing and the interference of the gear operation, the transmission parts will be damaged and the local temperature rise will be too high
