Problems solved by technology

In addition to the hand brake, the car also has a main brake. The main brake is also called a foot brake. The main brake is pressure-assisted, and the braking force of the main brake is very large; the car has a clutch driven by oil pressure, and the hydraulic drive oil circuit of the clutch can also be disconnected. To make the car unable to run, in the prior art, there is no car anti-theft device that disconnects the oil pressure of the clutch to drive the oil circuit

Embodiment Construction

[0027] Figure 1 to Figure 11 Among them, the car anti-theft control device has a sliding core type check valve 1 connected with a moving cam type electric trigger 2,

[0028] The sliding core type check valve has a valve body 3, and there are three stepped round holes in the valve body. The valve body cavity 4, the front end of the valve body cavity has an inlet 5, the side of the valve body cavity has an outlet 6 communicating with the inlet, and the inlet has a valve seat. 7. There is a valve stem 8 that can slide forward and backward in the inner cavity of the valve body. The rear end 9 of the valve stem protrudes from the rear side 27 of the valve body. The front end of the valve stem is embedded with an elastic valve core 10 that matches the valve seat. The elastic valve core Between the valve stem and the elastic valve core, there is a valve core coil spring 11 that can extend the force of the valve stem in the axial direction. There is a ring-shaped boss 12 on the valv...

Abstract

A vehicle anti-theft control device is provided with a slide core holding valve and a movable cam electric trigger that are connected; the body of the slide core holding valve is internally provided with a valve rod; the front end of the valve rod is embedded with an elastic valve core matched with a valve seat; a valve rod spiral spring is arranged at the valve rod; the movable cam electric trigger is provided with a motor, a speed reducer and a movable cam that are connected in sequence; the shaft of the motor is connected with the input terminal of the speed reducer; a gear and rack transmission mechanism is connected between the output terminal of the speed reducer and the movable cam; a cam profile curve is arranged at the movable cam along the linear direction; the valve rod is usedas the driven piece of the movable cam and the back end of the valve rod is butted with the cam profile curve. The device of the invention can be arranged on the vehicle to be combined with a stroke switch and a remote-control switch, thus being capable of leading the main brake of the vehicle to maintain a brake state and releasing the locking state of the brake, being capable of leading the clutch of the vehicle to maintain a separation state and releasing a separation locking state as well as preventing the vehicle from being stolen and rubbed. The anti-theft and anti-robbing performances of the vehicle anti-theft control device are good.

Description

technical field [0001] The invention relates to an automobile anti-theft control device, in particular to a main brake pressure pipeline control valve, a clutch oil circuit control valve and a driving device of the automobile anti-theft control device. Background technique [0002] Theft happens sometimes when the car is parked. In order to prevent the car from being stolen when it is parked, a car brake anti-theft device can be installed on the car. In the prior art, Chinese patent 90210685.6 discloses a car anti-theft device, which is mainly composed of an electrical control device and a hand brake locking mechanism. The electrical control device has a digital key switch control circuit, and the electrical control device is installed in the cab. The tightening mechanism is installed on the transmission case to control the clutch of the hand brake. When parking, after the hand brake is applied, the hand brake locking mechanism can lock the hand brake. Open the hand brake l...
