Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Realize a system for electric motor car with two wheels alighting gear automatic lifting, comprise pressure purger, control setup and jacking system.Pressure purger comprises by pass valve, and control setup comprises ball check valve, three position four-way directional control valve, and jacking system comprises double acting hydraulic cylinder.
The output port of fuel tank 1 is connected by connection pipe 1 one end with gear hydraulic pump 3, the other end of gear hydraulic pump 3 is connected with an input port of three position four-way directional control valve 8 by connection pipe 24, connection pipe 24 is provided with ball check valve 7, and the connection pipe 24 between gear hydraulic pump 3 and ball check valve 7 is connected with one end of connection pipe 35, the other end of connection pipe 35 is connected with an input port of fuel tank 1, connection pipe 35 is provided with by pass valve 6; Hydraulic oil sucks gear hydraulic pump 3 through connection pipe 1 from fuel tank 1.Hydraulic Pump shown in figure is gear type pump, but is not limited to gear type pump.Because the pressure of the hydraulic oil after gear hydraulic pump 3 acting is usually above required force value, connection pipe 35 is connected with connection pipe 24, regulation relief valve 6, the section hydraulic flowed out from gear hydraulic pump 3 oil is back to fuel tank 1 through connection pipe 35, realize with this effect that hydraulic oil that gear hydraulic pump 3 is discharged is reduced pressure, reach required pressure requirements; Post-decompression hydraulic oil flows into ball check valve 7 by connection pipe 24, and ball check valve 7 plays the effect regulating hydraulic fluid flow rate; Two ports of three position four-way directional control valve 8 same side are connected with connection pipe 49 one end with connection pipe 5 11 respectively, the other end connecting fluid cylinder pressure epicoele 13 of connection pipe 49, the other end connecting fluid cylinder pressure cavity of resorption 16 of connection pipe 5 11, double acting hydraulic cylinder 10 is fixed on vehicle frame, arrange hydraulic cylinder piston 14 in double acting hydraulic cylinder 10, double acting hydraulic cylinder 10 inner chamber is separated into hydraulic actuating cylinder epicoele 13 and hydraulic actuating cylinder cavity of resorption 16 by hydraulic cylinder piston 14; The lower end of hydraulic cylinder piston 14 is connected with one end of piston rod 15, and the other end of piston rod 15 is connected with footing 17 through double acting hydraulic cylinder 10 bottom surface through hole; Hydraulic cylinder piston 14 can slidably reciprocate in double acting hydraulic cylinder 10.An output port of three position four-way directional control valve 8 is connected with another input port of fuel tank 1 by connection pipe 6 12; Three position four-way directional control valve 8 has three control positioies.When three position four-way directional control valve 8 is in left position control position, the hydraulic oil being flowed into three position four-way directional control valve 8 by connection pipe 24 flows into hydraulic actuating cylinder epicoele 13 through connection pipe 49, hydraulic oil in hydraulic actuating cylinder epicoele 13 promotes hydraulic cylinder piston 14 and moves down, drive piston rod 15 protruding simultaneously, hydraulic oil in hydraulic actuating cylinder cavity of resorption 16 is through with the connection pipe 6 12 of three position four-way directional control valve 8 side through three position four-way directional control valve 8 through connection pipe 5 11, and flow back to fuel tank 1, realize with this object that alighting gear puts down automatically.When three position four-way directional control valve 8 is in meta control position, connection pipe 49 and connection pipe 5 11 are all closed, hydraulic oil in double acting hydraulic cylinder cannot free in and out, and the original mode of operation of maintenance medium pressure cylinder piston 14, realizes with this object that alighting gear immobilizes, battery-driven car is steadily parked.When three position four-way directional control valve 8 is in right position control position, hydraulic oil flows into hydraulic actuating cylinder cavity of resorption 16 through connection pipe 5 11, and promote hydraulic cylinder piston 14 moves, drive piston rod 15 inwardly indentation simultaneously, the connection pipe six 12 of hydraulic oil in hydraulic actuating cylinder epicoele 13 through connection pipe 49, three position four-way directional control valve 8 and three position four-way directional control valve 8 side flows back into fuel tank 1, reaches the object of alighting gear automatic drawing back with this.
The utility model is comparatively simple, is easy to the automatic lifting realizing electric motor car with two wheels alighting gear.The size of double acting hydraulic cylinder 10 will match with the size of vehicle body, is convenient to install to reach and does not affect the object that battery-driven car normally travels.The hydraulic actuating cylinder epicoele 13 that connection pipe 49 is connected to double acting hydraulic cylinder 10 is convenient to input and the discharge of hydraulic oil, and the hydraulic actuating cylinder cavity of resorption 16 that connection pipe 5 11 is connected to double acting hydraulic cylinder 10 is convenient to input and the discharge of hydraulic oil.Connection pipe 49 and connection pipe 5 11 Dou Youyige branch, the position of branch should away from connection pipe 49 and connection pipe 5 11 junction with double acting hydraulic cylinder 10, ensure that the force value of the hydraulic oil being transported to two double acting hydraulic cylinders 10 is identical with this, two footing can be elevated simultaneously, avoid the situation occurring that adjustable height differs, improve the stability that battery-driven car is parked.
