[0004] (1) Due to the low oil inlet temperature of the lubricating oil for cooling, when the lubrication system is started at low temperature, the viscosity of the oil is high when the oil temperature is very low, especially, because the vehicle generally works outdoors, in extreme cases where the ambient temperature is very low , the viscosity of the oil is very high, which leads to poor oil return due to gravity, resulting in continuous accumulation of lubricating oil inside the gearbox, causing high pressure inside th

Abstract
The invention discloses a lubricating cooling system for a vehicle gear box. The system comprises an oil tank, an oil feeding pump, a first variable frequency motor, a first temperature sensor, an oil returning pump, a second variable frequency motor and a controller, wherein the first variable frequency motor is used for driving the oil feeding pump to pump oil from the oil tank and then inputting to an oil inlet of the vehicle gear box; the first temperature sensor is used for measuring the temperature of the oil in the oil tank; the controller is used for acquiring various sensor signals in the system and performing feedback such as controlling and alarming. The system is particularly applicable to the lubricating of a vehicle working in a low-temperature environment, and the controller can control the first variable frequency motor to work at a low gear in the low-temperature environment; the torque of the first variable frequency motor is in match with the viscosity of oil, so that the service life of the motor can be prolonged; the oil returning pump is arranged and can be used for pumping lubricating oil accumulated in the gear box, and thus the lubricating oil can be effectively prevented from being accumulated in the gear box.
Description
technical field [0001] The invention relates to a vehicle gearbox cooling system, in particular to a lubrication cooling system for a vehicle gearbox. Background technique [0002] With the development of the mining industry, the demand for large-tonnage engineering vehicles continues to increase. The wheel-side reducer in the gearbox on large-tonnage engineering vehicles has a large driving power and a compact structure, resulting in high heat generation in the gearbox. The heat dissipation cannot fully meet the cooling requirements, and some large-tonnage engineering vehicle reducers have begun to use external circulation oil supply for lubrication and cooling. [0003] The Chinese patent with the application number 201320815164.0 discloses a lubricating and cooling system for a wheel-side reducer, including a hydraulic pump unit, a drive unit, a filter unit and a cooling unit. The drive unit is connected to the hydraulic pump unit, and the oil suction port of the hydrauli...
