Definitions
- the present invention relates to a vehicle brake device, and more particularly to a hydraulically controlled hydraulic anti-lock brake device.
- An anti-lock brake device is a device that can prevent a wheel from being completely locked and losing control when the vehicle is braked.
- newly developed cars are generally equipped with such devices.
- the braking performance of the four wheels is inconsistent, and some of the wheels are locked, resulting in deviation, loss of control and side slip.
- anti-lock braking devices have been developed.
- the anti-lock brake device includes a sensor, a controller, and a regulator.
- the controller and regulator are typically microprocessors.
- the master cylinder When the driver steps on the brake pedal, the master cylinder outputs a certain amount of hydraulic pressure to the cylinder according to the magnitude of the pedal force.
- the sensor mounted on the wheel monitors the change in the angular velocity of the wheel and immediately transmits the information to the controller. Once the controller detects a large change in angular velocity, it issues a command to the regulator to adjust the brake pressure of the wheel brake cylinder.
- the size of the electronic ABS is large, and the finished car does not necessarily have enough space to install the electronic ABS.
- the electronic ABS starts to act at the moment when the wheel is locked, and acts 6 to 12 times per second, increasing the frequency of the brake, making the brake The braking force is more linear, the braking is more stable, and the braking distance can be reduced.
- the frequency of the point brake is realized by the commutation of the solenoid valve, because the response speed of the coil in the solenoid valve determines the frequency of the point brake can no longer be Improvement, therefore also determines that the existing brake structure is unlikely to significantly reduce the braking distance.

- the brake oil rainbow is two and oppositely disposed.
- the output end of the one-way valve is connected with a hydraulically controlled two-position three-way valve

Movement, driving the friction piece to quickly contact with the brake drum or disc of the car to achieve braking.
- the work of the impact force instead of the friction force can greatly shorten the braking distance.
- the friction braking is performed by The two straight lines are the steep line with steep speed drop at the beginning of deceleration and the oblique line with small slope at the later stage.
- the acceleration -a is large, resulting in a large rotational inertia force and a braking frequency of 300 times/second.
- the dynamic frequency, the impact force is achieved, and the braking curve is A diagonal line with a small slope, the acceleration - a is small, the inertial force is small, and the braking distance is greatly shortened.
- the anti-lock brake device can avoid the direction of the brakes during the emergency braking and the side slip of the wheel, so that the wheel is not locked when the brake is braked, and the tire is not rubbed against the ground at one point, thereby increasing the friction force, so that the friction force is increased.
