Piston pushes the movement of steel column 9 to push the movement of corresponding stator 2 to be braked；Pressure in 2 high pressure chest of stator is gradually increasing, high pressure
The brake fluid of intracavitary flows into corresponding anti-lock valve 11 by pipeline from high pressure liquid port 12, and brake fluid pushes the blade in stator 2
Rotor 3 is prevented to rotate, the size of high pressure brake fluid pressure is reflected as the size of brake force, and vehicle inertia is moved by the opposite of road surface
Dynamic, the frictional force generated by gravity turns a wheel, and wheel is rotated synchronously with rotor 3, and rotor 3 is with blade with angle in stator 2
Intracavitary rotates, and since bias occurs for 2 inner cavity of stator and rotor 3, the variation of rotor 3, blade and 2 inner wall of stator composition space makes brake
Vehicle oil pressure increases, when the oil pressure that brakes is raised to more than the pressure of liquid in force samples cylinder 15 in vehicle bridge so that anti-lock
11 inner plunger of valve is moved to the side being connected to force samples cylinder 15, and the high pressure brake fluid in anti-lock valve 11 passes through low pressure liquid end
Mouth 13 is back in 2 low pressure chamber of stator, so that the pressure in 2 high pressure chest of stator does not continue to rise, the resistance on wheel
It is initially located in constant, wheel is made to keep best braking state continuous braking (as shown in Figure 2)；When vehicle backing emergency brake,
On the contrary, high pressure brake fluid is from another anti-lock in stator 2 when the flow direction of brake fluid and vehicle advance emergency braking in stator 2
Valve 11 flows into, and is then refluxed for (as shown in Figure 4) in 2 low pressure chamber of stator；
When meeting rainwater weather emergency braking, corresponding rainwater selector valve 17 is opened, it is high from the part that 2 high pressure chest of stator flows out
Pressure brake fluid enters rainwater road brake valve 16, and the pressure in rainwater road brake valve 16 rises to push T shapes column to anti-lock valve 11
Side movement, T shape columns push the plunger in anti-lock valve 11 quickly to side movement be connected to force samples cylinder 15, to make
The high pressure brake fluid obtained in anti-lock valve 11 is quickly back to from low pressure liquid port 13 in the low pressure chamber of stator 2, and it is high to accelerate stator 2
