The specific embodiment
According to Fig. 1, provide concrete exemplifying embodiment of the present invention below, so that better understand function of the present invention, characteristics.
The present invention is that a kind of recover kinetic energy stores the system that utilizes, kinetic energy when car retardation is braked is converted into hydraulic pressure potential energy and stores in the hydraulic accumulator group, and the back pressure during the hydraulic actuating cylinder compress energy storage is delivered to vehicle transmission system or is directly delivered to by messenger chain as load and realizes brake snub on the axletree; And vehicle launch is when quickening, and is discharged into the high-voltage oil liquid in the hydraulic accumulator in the hydraulic actuating cylinder and then drives hydraulic cylinder piston, drives the final powered vehicle operation of whole messenger chain.
Fig. 1 is a structure diagram of the present invention.As shown in Figure 1, vehicle energy is by the belt input at input shaft 14 places of retarder 11; At output shaft 13 places via gear transmission; Arriving power-transfer clutch 9,10 outputs on the rope sheave 5,8; Rope sheave is via rope 15; Drag hydraulic actuating cylinder 4,7 pistons, extruding fluid; Fluid flow into the energy storage house steward by oil cylinder on-off valve 3,4; Enter into energy storage 1 through hydraulic accumulator control cock 2 again, thereby the conversion hydraulic pressure potential energy of kinetic energy is stored; When vehicle launch quickened, high-voltage oil liquid was flowed out by hydraulic accumulator 1, entered the Driven by Hydraulic Cylinder piston motion through on-off valve 2,3,6 regulation and control, and rope oppositely spurs rope sheave, drives the retarder antiport, and kinetic energy is delivered on vehicle transmission system or the wheel shaft.Wherein, system can be equipped with many group hydraulic actuating cylinder-rope sheaves, and every group all has power-transfer clutch and oil circuit and the on-off valve that has as shown in Figure 1.When system transformed storage kinetic energy, controller hydraulic pressure on-off valve 16,17 opened circuit, and prevented that the direct earial drainage of high-voltage oil liquid quilt is to fluid reservoir 12; Whether engage and on-off valve 3,4 by control clutch 9,10, come the hydraulic actuating cylinder-pulley set quantity of Control work, thus the pressure oil flow of modulated pressure oil circuit, and the hydraulic accumulator quantity that the quantity decision that on-off control valve 2 is connected is worked simultaneously; And flow is big more, and working hydraulic pressure energy storage quantity is more little simultaneously, and then the pressure ascending velocity of hydraulic circuit is fast more, and the lock torque that system realized is directly proportional with the pressure of hydraulic circuit, and all the more fast speed promotes lock torque; When the pressure in the hydraulic circuit was identical, lock torque was directly proportional with the hydraulic actuating cylinder-pulley set quantity of work; And when the hydraulic accumulator in the system reached maximum functional pressure, system can cut off control corresponding valve 2, made this energy storage detach hydraulic circuit and avoided damaging energy storage; Control system also can insert the loop with the energy storage of different pressure, realizes the pressure between the highest and minimum pressure in the loop; Can control the size of brake snub moment to a certain extent freely by above-mentioned means system, control brake process on one's own initiative, thus the safety that guarantees vehicle operating is with steadily comfortable.
