A kind of electronic hydraulic brake system, comprising: conveying equipment；Suitable for conveying hydraulic oil；Energy storage device is suitable for storage institute
State hydraulic oil；It is connect through pressure duct 15 with conveying equipment；The above-described fixed caliper with parking function, each rear car
Wheel setting one；Energy storage device passes through the driving pipeline with each fixed caliper with parking function respectively of hydraulic tube 16
7 are connected to parking pipeline 6, and are provided with solenoid valve on each hydraulic tube 16, wherein being with the solenoid valve of driving piping connection
Driving solenoid valve, the solenoid valve with parking piping connection are parking solenoid valve.
As shown in figure 9, electronic hydraulic brake system is generated high pressure by conveying equipment and flowed into energy storage device, electromagnetism is controlled
Valve perhaps discharges to the fixed caliper input with parking function of left rear wheel and off hind wheel hydraulic thus release or lock respectively
Tight brake disc 1 travels vehicle smoothly and parking.
In one particular embodiment of the present invention, conveying equipment uses hydraulic pump or ESP control unit；Energy storage device
For high-voltage energy storage tank.ESP control unit is the control unit of ESP body stabilization system, wherein being integrated with ESP pump, the present invention is adopted
Use ESP control unit as conveying equipment i.e. electronic hydraulic brake system of the present invention and ESP body stabilization system
It integrates, the two shares control unit.
Preferably, pressure duct 15 is equipped with check valve, it is maintained at after hydraulic pump stops not countercurrently, keeps high pressure storage
The leakproofness of energy tank.
When vehicle launch, the self-test of ESP control unit and pressure is built to high-voltage energy storage tank, parking solenoid valve control pipe, which presses to, stays
Vehicle oil pocket 202 releases stress, and releases the parking brake force of disk spring, and vehicle can normally be driven a vehicle.In vehicle travel process,
When using service brake, driving solenoid valve control pipe presses to service brake chamber 3 and releases stress, and applies pressure to rear service brake disk 1,
ESP control system works or drive a vehicle solenoid valve starting anti-lock function simultaneously, controls the pressure in service brake chamber 3, anti-
Only there is locking phenomenon in rear-wheel.
When driver pulls parking button, worked when vehicle does not stop by ESP control system or parking electromagnetism
Valve starts anti-lock function, controls the pressure in parking oil pocket 202, prevents rear-wheel from locking phenomenon occur.After vehicle stops, drawing
Parking brake button is played, the pressure in parking oil pocket 202 releases completely at this time, and the parking power that disk spring generates is applied to completely
On rear service brake disk 1, guarantee that vehicle being capable of safe parking on ramp.
By taking the piston component of left end as an example, each state lower piston motion conditions are as follows:
Parking braking releases: the loine pressure of parking solenoid valve release is transmitted to parking oil pocket by parking general pipeline 601
The right side of parking piston 8 in 202 pushes parking piston 8 that the effect of disk spring is overcome to move to left, and parking piston 8 moves to left rear in
Between piston 9 be detached from, under the action of driving piston 10 does not stress, outer knockout press that friction block 11 generates when being rotated by brake disc 1
Effect is lower to be retreated, and parking braking is released.
Parking braking: after vehicle stops, parking solenoid valve releases the pressure in pipeline, and parking piston 8 is no longer influenced by height
The effect of pressure, therefore disk spring pushes parking piston 8 to move right, and pushes intermediate piston 9 to move right, intermediate piston 9 pushes away
Dynamic driving piston 10 and friction block 11 move to right, and clamp brake disc 1 together with the friction block 11 on 1 right side of brake disc, generate parking and make
With.
Service brake: the loine pressure of driving solenoid valve release, by driving a vehicle, general pipeline 701 is transmitted in service brake chamber 3
The left side of driving piston 10 pushes driving piston 10 to move to right, and driving piston 10 pushes friction block 11 to move to right, on the right side of brake disc 1
Friction block 11 clamp brake disc 1 together, generate driving effect.
