Abstract

The invention relates to the technical field of brake system emptying, and discloses a vehicle brake system emptying device and method. The emptying device comprises a shell, vacuum pumps, a brake fluid recovery unit, a first connecting pipe and a second connecting pipe, wherein the vacuum pumps, the brake fluid recovery unit, the first connecting pipe and the second connecting pipe are arranged on the shell; the vacuum pumps are connected with the brake fluid recovery unit through the first connecting pipe; one end of the second connecting pipe is connected with the brake fluid recovery unit, and the other end of the second connecting pipe is provided with a connector used for being connected with an exhaust port of a brake system; the second connecting pipe is provided with a transparent observation section. In the brake system emptying process, negative pressure is provided by the vacuum pumps and used for pumping brake fluid carrying air, whether the emptying process is over or not is determined by observing whether air exists in the brake fluid in the corresponding connecting pipe, an air pressure source is not needed in the whole emptying process, and use of the emptying device is not limited by working areas. In addition, the connector is a flexible connector and suitable for exhaust ports, in different sizes, of vehicle brake systems.

Description

technical field [0001] The invention relates to the technical field of braking system emptying, in particular to a vehicle braking system emptying device and method. Background technique [0002] When a new car comes off the assembly line or the vehicle brake system is repaired, the vehicle brake system needs to be emptied and filled with brake fluid. When emptying and filling brake fluid, if there is air in the hydraulic brake system pipeline of the car, it will affect the braking performance of the car and the feeling of the pedal. [0003] Brake fluid filling machines are generally used in trial production test workshops, car repair shops and other places to empty the brake system and add brake fluid. The brake fluid filling machine is mainly composed of: liquid storage tank, liquid and gas pipeline, liquid and gas pipeline control valve, filling port and so on. During the working process of the brake fluid filling machine, after the liquid storage tank of the filling m...
