A portable vehicle oil circulation device and its working method

Abstract

The invention discloses a portable vehicle oil line circulating device and a working method thereof and relates to a vehicle overhauling device. In an oil line of a coach clutch operation system and an oil line of a lifting platform accelerator system of an automobile crane, air is particularly hard to exhaust from pipelines because long hydraulic pipelines of the oil lines are laid and are relatively complicated. The device disclosed by the invention comprises a hydraulic system and an electric system, wherein the hydraulic system comprises an electro-motor, a hydraulic pump, an overflowing valve, a first interface, a second interface and an oil tank; the hydraulic pump is connected with the electro-motor; an oil outlet of the hydraulic pump is connected with an oil inlet of the overflowing valve through an oil pipe; the oil outlet of the overflowing valve is connected with the first interface through the oil pipe; a pressure relief hole of the overflowing valve is connected with an oil returning pipeline; the second interface is connected with the oil tank; the first interface is arranged at the lower part of the oil tank; the second interface is arranged at the upper part of the oil tank; a returned oil filter connected with the second interface is arranged inside the oil tank; the electric system comprises a power switch, a positive terminal and a negative terminal. The device disclosed by the invention is simple in structure, capable of alleviating the labor intensity of a worker, and flexible and convenient to operate.

Description

technical field [0001] The invention relates to a vehicle maintenance device, in particular to a portable vehicle oil circuit circulation device. Background technique [0002] At present, the clutch control system of heavy goods vehicles, passenger cars and other vehicles and the accelerator system of the suspension platform of automobile cranes are all controlled by hydraulic system. Taking passenger cars as an example, the clutch control system uses the driver's foot to step on the clutch master cylinder pedal to form pressure in the clutch control system, open the clutch sub-pump oil valve, and introduce high-pressure air into the vehicle's air circuit system to push the piston in the clutch sub-pump to move. Thereby pushing the clutch fork to impel the clutch to disengage. However, after the vehicle clutch control system breaks down and needs to replace its clutch master cylinder or sub-cylinder, it is difficult to remove the air in the hydraulic line. At present, ther...

Problems solved by technology

This method is only suitable for maintenance in the factory area, and it is easy to cause oil pollution in the cab, making cleaning difficult

Especially for the oil circuit of the passenger car clutch control system and the oil circuit of the throttle system of the automobile crane platform, due to the long and complicated laying of the hydraulic pipelines, it is particularly difficult to remove the air from the pipelines
