Sealing ring is installed between the inner ring and outer ring and the annular groove 37 of the first cylinder body 28 of ring 20 among the cylinder body.
The operation principle of the present invention is that：
Referring to Fig.1 1, when normal vehicle operation, the power that engine 46 is connected to retarder 51 by gearbox 50 is defeated
Enter end, the power output end of retarder 51 transmits power to drive axle 48 through transmission shaft 18 by universal joint 47, to drive
Vehicle wheel rotation；When vehicle braking is slowed down, brake pedal 49, retarder 51 is started to work, and fluid is through low pressure accumulator 55
It is flowed in high pressure accumulator 52 by retarder 51, high-voltage energy-storage is stored in convert the kinetic energy of vehicle traveling to hydraulic energy
In device 52, this is retarder " pump " operating mode；When vehicle launch or acceleration, pedal 53 of stepping on the throttle stores in braking process
High pressure oil in high pressure accumulator 52 is flowed to through retarder 51 in low pressure accumulator 55, to drive retarder 51 to rotate, then
It is transmitted power on drive axle 48 by universal joint 47 through transmission shaft 18, drives vehicle wheel rotation, play the role of power-assisted, realize liquid
For pressure energy to the conversion of kinetic energy, this is retarder " motor operating conditions ".
When retarder is operated in " pump " operating mode：The transmission shaft 18 of retarder 51 rotates, and drives the first cylinder body 28 and the second cylinder
Body 19 rotates, after ECU 54 receives brake signal, by adjusting two the first variable pistons 6 and two the second variable pistons 11
Displacement, to make that there is certain bias between the first needle bearing 26 and the second needle bearing 21 and the axis of transmission shaft 18
Amount, and eccentric direction is opposite.Make plunger 31 when with the first cylinder body 28 and the rotation of the second cylinder body 19, also respectively in plunger hole
It is radially reciprocated in 34 so that when plunger 31 moves out, 34 volume of plunger hole increases, and plunger hole 34 passes through it at this time
The slotted hole 36 of lower part is connected to oil suction arc slot 39, and then oily from outside sucking by left fuel feed hole 41 or right fuel feed hole 43
Liquid, when plunger 31 is pressed into plunger hole 34, volume reduces, the slotted hole 36 and pressure oil arc that plunger hole 34 passes through its underpart at this time
Slot 40 is connected to, and then is extruded fluid by left oil outlet 42 or right oil outlet 44, and multiple plungers 31 work at the same time, so that it may with
Realize that continuously either right fuel feed hole 43 sucks fluid from 44 row of left oil outlet 42 or right oil outlet from left fuel feed hole 41
Degreasing fluid.Just the course of work phase of " pump condition " is operated in when retarder 51 is operated in " motor operating conditions " with above-mentioned retarder 51
Instead.
The automatic Compensation Technology of the retarder is：
Due to the annular groove 37 on the first cylinder body 28 by check valve 27 be communicated to plunger hole 34 finally with pressure oil arc slot 40
Connection, therefore will be filled with the hydraulic oil of certain pressure in annular groove 37, due to the first cylinder body 28 and the second cylinder body 19 and transmission shaft
Allow opposite sliding between 18, therefore the first cylinder body 28 and the second cylinder body 19 pass through ring among cylinder body 20 under the action of hydraulic coupling
It keeps compressing with the first valve plate 4 and the second valve plate 15 respectively；When the first valve plate 4 or the second valve plate 15 are respectively with
One cylinder body 28 when either the second cylinder body 19 is worn hydraulic coupling so that the first cylinder body 28 or the second cylinder body 19 is done corresponding movement
Wear extent is made up, while the axial force suffered by the first cylinder body 28 and the second cylinder body 19 can be offset accordingly, due to the first cylinder body
28 and second have relative movement between cylinder body 19 and transmission shaft 18, also ensure that transmission shaft 18 is not influenced by axial force.
