Be described further below in conjunction with enforcement accompanying drawing.
As shown in Figure 1, the hydraulic hybrid energy conserving system on a kind of loader comprises: driving engine 1, transmission output shaft 2, torque couplings 3, drive axle 4, power-transfer clutch 5, hydraulic reservoir 6, pump motor 7, two position switching valve 8, by pass valve 9, high pressure accumulator 10, control unit 11, brake pedal 12, throttle sensor 13 etc.
Introduce when the hydraulic hybrid energy conserving system on a kind of loader works below, the service condition of each several part:
The power that driving engine 1 sends arrives drive axle 4 by transmission output shaft 2, torque couplings 3, thus drives loader motion.Torque couplings 3 is connected between transmission output shaft 2 and drive axle 4, the other end of torque couplings 3 is connected by power-transfer clutch 5 with pump motor 7, when chaufeur steps on brake pedal, when loader carries out Reduced Speed Now, control unit 11 receives the signal from brake pedal 12, under control of the control unit 11, power-transfer clutch 5 is in engagement state, two position switching valves 8 are in right lateral position state, pump motor 7 is in pump condition, now power is through drive axle 4, torque couplings 3, power-transfer clutch 5 arrives pump motor 7, because pump motor 7 belongs to pump condition under control of the control unit 11, therefore the hydraulic oil in hydraulic reservoir 6 is pumped in high pressure accumulator 10 by oil pipe through two position switching valves 8 by pump motor 7, thus realize the recovery of braking energy and be converted into hydraulic energy and store.
When loader starting or spading, control unit 11 receives the signal from throttle sensor 13, under control of the control unit 11, power-transfer clutch 5 is in engagement state, two position switching valves 8 are in right lateral position state, pump motor 7 is in motor operating conditions, hydraulic oil in high pressure accumulator 10 arrives pump motor 7 through two position switching valves 8, because pump motor 7 is in motor operating conditions under control of the control unit 11, therefore hydraulic oil hydraulic energy transfer after pump motor 7 is mechanical energy, and through power-transfer clutch 5, torque couplings 3 arrives drive axle 4, auxiliary traction power is provided, realize the utilization again of complementary energy, and avoid driving engine to turn round phenomenon, it is made to be in best fuel-economy district.
