Device is fixedly linked, and pressure-bearing type braking swash plate is fixedly connected in the outer pump housing, it is inclined-plane, the outer pump housing that pressure-bearing type, which brakes swash plate braking surface,
Inside have cylinder body, 11 be axially equipped on cylinder body with upper plug, pressure-bearing type braking swash plate braking surface correspondence is equipped with return plate, flexural pivot with
There are spring, plunger to be connected by return plate between cylinder body, outer pump housing lower end has oil distribution casing, plunger total with controller by oil distribution casing
At being connected.
The present invention has the advantages that：The brake system of car is connected with drum brakes due to using in brake rim
Piece connects brake(-holder) block oil cylinder between double-drum type brake block, is rotatably connected to driven drum in double-drum type brake block, rotation in driven drum
It is connected with the above hydraulic pump in axial 11 holes, outer pump housing one end is fixedly linked with suspension, and brake(-holder) block oil cylinder on driven bulging wall by leading to
The optimization structure that road is connected with control assembly, thus improve braking effect.Thus the brake system of car has braking
Effect is good, the short feature of braking distance.
Description of the drawings：
Attached drawing 1 is schematic structural view of the invention.
1- brake rims in figure, 2- drum-type brake pads, 3- brake(-holder) block oil cylinders, the driven drums of 4-, the outer pump housings of 5-, the braking of 6- pressure-bearing types
Swash plate, 7- return plates, 8- plungers, 9- oil distribution casings, 10- cylinder bodies.
Specific implementation mode：
The invention will be further described below in conjunction with the accompanying drawings：
As shown in the picture, which includes brake rim 1, drum-type brake pad 2, brake(-holder) block oil cylinder 3 and driven drum
4.It is connected with drum-type brake pad 2 in brake rim 1, brake(-holder) block oil cylinder 3 is connected between double-drum type brake block 2, double-drum type brake block 2 connects
It is connected on driven drum 4, the above hydraulic pump in axial 11 holes, 5 one end of the outer pump housing and suspension stationary phase is rotatably connected in driven drum 4
Even, brake(-holder) block oil cylinder 3 is connected by 4 wall upper channel of driven drum with control assembly.
The described axial 15 hole hollow shaft hydraulic pumps include the outer pump housing 5, pressure-bearing type braking swash plate 6, return plate 7, plunger 8,
Oil distribution casing 9 and cylinder body 10.The outer pump housing 5 is dynamiclly connected by the bearing on the axle in driven drum 4,5 one end of the outer pump housing and lower swing arm
It is connected to a fixed with shock absorber, pressure-bearing type braking swash plate 6 is fixedly connected in the outer pump housing 5, pressure-bearing type braking 6 braking surface of swash plate is
There is cylinder body 10 on inclined-plane in the outer pump housing 5,15 plungers 8 is axially equipped on cylinder body 10,8 end of plunger is connected with plunger piston slippery boots, plunger
8 ends are in contact with 6 inclined-plane of pressure-bearing type braking swash plate, and pressure-bearing type braking 6 braking surface of swash plate correspondence is equipped with return plate 7, return plate 7
It is connected in the outer pump housing 5 by flexural pivot, there is spring, plunger piston slippery boots to be connected by return plate 7 between flexural pivot and cylinder body 10, the outer pump housing
5 lower ends have oil distribution casing 9, plunger 8 to be connected with control assembly by oil distribution casing 9.When automobile normal running：Brake rim 1 rotates,
Drum-type brake pad 2, driven drum 4, brake(-holder) block oil cylinder 3, return plate 7, cylinder body 10 do not rotate.When brake：It is drum-type brake pad 2, driven
Drum 4, brake(-holder) block oil cylinder 3, return plate 7, cylinder body 10 rotate.
Operation principle：
The brake system of car control assembly controls drum-type brake pad 2 by brake(-holder) block oil cylinder 3 and is connected with brake rim 1,
Driven drum 4 is driven to rotate, driven drum 4 drives cylinder body 10 to rotate by tooth, and rotation 15 plungers 8 of drive of cylinder body 10 do not stop cycle and make
Oil suction and oil extraction campaign, the outer pump housing 5, pressure-bearing type braking swash plate 6 and oil distribution casing 9 do not rotate, since control assembly controls plunger 8
Oil extraction flow and pressure, also just control plunger 8 and pressure-bearing type brake frictional force between swash plate 6, and then reduce vehicle wheel rotational speeds,
Reach braking purpose, finally improve braking effect, 100 kilometers of speed per hour test braking distances are shortened by existing 40 meters or so per hour
Be 25 meters or so, sandstone, ice face, Shi Shuo, ice and snow road surface on play a role it is more preferable.
When namely needing braking, pedal brake pedal, since central controller ECU controls high pressure pressure regulation electricity proportional damping
Valve and unidirectional electric proportional dump valve, the pressure to limit high-pressure oil outlet turn with the axial 15 hole hollow shaft hydraulic pumps of flow control
Speed, axial 15 hole hydraulic pump control vehicle wheel rotational speeds, plays braking purpose, wheel can gradually be pressed with the speed per hour of 6-3-0km/h at this time
Ratio rotating speed declines rotation, and body of a motor car is at this time with the speed of 100km/h with respect to ground motion, and wheel is with 6-3-0km/h speed
The opposite ground rotation of degree, which is formed when rolling rubs with dragging, forms most effective brake force.When wheel is with the rotating speed of 6-3-0km/h
When rotation, automobile is set to play direction controllable.
