Embodiment approach

[0034] When the three-contact switch 13 is connected to the zero line contact 132, the system is in a power-off state, and the pump body 1 performs the parking function by mechanical control. When the brake pedal is stepped on, the second one-way valve 24 is opened, and the brake The dynamic fluid flows from the brake master cylinder to the second sub-oil passage 23 through the second main oil passage 22, and the two second sub-oil passages 23 are respectively connected to the brake cylinders, and through the brake cylinders, the parking function is completed.

[0035] When the three-contact switch 13 is connected with the manual control contact 133, the system is fully powered on, and at this time, the working current passes through the manual control contact 133 and the diode 19 to the electromagnetic coil 8, and then passes through the third sensor relay switch 18 Back to the negative pole of the power supply, the magnetic force generated by the electromagnetic coil 8 attrac...

Abstract

The invention relates to an electromechanical integrated fully automatic parking pump valve, and solves the problems that the traditional parking method has poor performances and the parking method is single. The parking pump valve comprises a mechanical part and an electronic control part, wherein the mechanical part comprises a pump body, a pump cover and a housing, and a plunger is arranged in the cylindrical inner cavity of the pump body; the cylindrical inner cavity of the pump body is divided into a front cavity and a back cavity by the plunger, and one end of the plunger in the back cavity is connected with a spring; the other end of the plunger is in contact with the side wall of the cylindrical inner cavity of the pump body, and a group of electromagnetic coils for generating a magnetic field force is arranged between the housing and the pump body; and the electronic control part comprises a manual control circuit and an automatic control circuit which are respectively connected with the electromagnetic coils.

Description

technical field [0001] The invention relates to an electromechanical integrated fully automatic parking pump valve, which belongs to the field of parking pump valves. Background technique [0002] The commonly used parking forms are various. At present, the middle and low-end cars generally use the handle pull-wire parking method for parking, while the high-end cars use the motor-pulled wire type parking or the computer directs the electric oil pump to perform parking. Using the above parking methods, it is necessary to Manual operation takes up a lot of space in the cab, complex structure or poor performance, single parking method, and high cost. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides an electromechanical integrated fully automatic parking pump valve, which solves the problem that the traditional parking method requires manual operation, takes up a large space in the driver's cab, has poor performance...
