Abstract
The utility model relates to an automotive brake auxiliary device, in particular to an oil cut-off device for automotive brakes, with the aim of solving the potential hazard problems in the prior art,arising from the mechanical brake approach adopted in stopping vehicles. The device comprises brake slave cylinders installed in the positions of the wheels, an oil supply master cylinder and a three-way valve, wherein, an oil cut-off valve is connected in series on the pipeline connected between the three-way valve and the oil supply master cylinder; and, in terms of construction, the oil cut-off valve comprising a valve body and a rotatable valve core, wherein, an oil inlet hole and an oil outlet hole are formed on the valve body, and an oil passage is formed on the valve core. The benefitsof such as structure involves keeping the wheels in a fixed state, transforming the mechanical brake to oil brake, enabling vehicles to stand still, and ensuring the safety of personnel in checking on and repairing vehicles.
Description
Technical field
The utility model relates to a kind of vehicle brake auxiliary device, is specially a kind of vehicle oil oil-break device of stopping.
Background technology
In present vehicle design, when needing parking maintenance under vehicle et out of order or other situations, generally to use parking brake not make it mobile with vehicle stationary or with other add-on device fixing vehicle wheels.Must limitation but the mode of this mechanical brake has, safety factor is not high, vehicle is slided suddenly and brings potential safety hazard.
Summary of the invention
The utility model uses the problem of the hidden danger that the mechanical brake mode brings when solving the vehicle parking that exists in the prior art and a kind of vehicle oil oil-break device of stopping is provided.
The utility model is realized by following technical scheme, a kind of vehicle oil oil-break device of stopping, comprise the wheel cylinder that is installed in the wheel position, fuel feeding master cylinder, threeway, be serially connected with oil cut-off valve on the bonded assembly pipeline between threeway and the fuel feeding master cylinder, the structure of oil cut-off valve comprises valve body, revolvable spool, has fuel feed hole and oil outlet on the valve body, has oil channel on the spool.
Compared with prior art, the utility model has installed oil cut-off valve additional in original brake system, under normal circumstances regulating the oil-break spool makes oil circuit keep unimpeded, when the situation of parking maintenance occurs if desired, can stepping on brake earlier makes vehicle be in oil to stop under the state, the spool that rotates oil cut-off valve then blocks oil circuit, oil in the wheel cylinder returns less than in the fuel feeding master cylinder, make wheel be in stationary state, becoming machinery stops and stops into oil, vehicle can firmly be parked in as you were, and personnel can overhaul vehicle safely.
