Abstract
The invention discloses an energy storage hydraulic braking system for an automobile. The system mainly comprises a hydraulic pump/motor, a hydraulic accumulator, an oil path distribution control valve and an operating system. The energy storage hydraulic braking system for the automobile is arranged in an original transmission system of the automobile to replace an original frictional braking system. In an automobile braking process, the hydraulic pump/motor connected with a gear on the opening of a power takeoff assembly of a transmission is connected through a control system and the hydraulic accumulator realizes recycling braking energy through the hydraulic pump/motor. In an emergency braking process, a brake pedal is further stamped and the original frictional braking system acts. When the automobile accelerates, pressure oil in the accumulator drives the hydraulic pump/motor to rotate so that an auxiliary power source for a power-driven system of the entire automobile is formed and the entire automobile has double-power driving capacity. Therefore, the aims of saving fuel oil, reducing emission and enhancing the safety performance of the automobile are fulfilled.

Beneficial effect of the present invention is as follows:
Energy-storage type hydraulic braking system for automobile of the present invention is mainly by hydraulic pump/motor, hydraulic accumulator and oil circuit distribute control module to form, hydraulic accumulator and hydraulic pump/motor realize that brake energy reclaims and the acceleration energy release function, to constitute car load power drive line auxiliary power source, car load will have the two-motor drive ability, double dynamical realization relies on change-speed box propulsion box ability to speak wheel and connects a hydraulic pump/motor, the power of hydraulic accumulator is taken to the inertia when vehicle brake, because hydraulic accumulator has bigger specific power, therefore can realize the quick recovery and the release of big kinetic energy.The invention has the beneficial effects as follows: energy formula hydraulic braking system for automobile of the present invention is housed, under the prerequisite that does not change orthodox car chassis structure and driving engine, drive assembly by on the chassis, installing a cover hydraulic regenerating additional, the braking energy that major part is wasted usually effectively reclaims storage, and utilizes on vehicle quickens, and saves fuel oil, reduces discharging, improves vehicle safety performance thereby reach.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Number in the figure: driving engine 1, first clutch 2, change-speed box 3, power taking window gear 4, second clutch 5, wheel 6, drive axle 7 drives hydraulic pump/motor 8, change-over valve 9, oil pipe 10, energy storage 11, sequence valve 12, by pass valve 13, accelerating throttle pedal 14, the first travel switches 15, brake pedal 16, the second travel switches 17, master brake cylinder 18.
The specific embodiment:
As shown in Figure 1, first clutch 2 links to each other with driving engine 1, change-speed box 3 links to each other with first clutch 2, wheel 6 links to each other with change-speed box 3 by drive axle 7, a kind of energy-storage type hydraulic braking system for automobile of the present invention, comprise a power taking window gear 4, power taking window gear 4 links to each other with change-speed box 3, second clutch 5 links to each other with power taking window gear 4, driving hydraulic pump/motor 8 links to each other with second clutch 5, change-over valve 9 links to each other with driving hydraulic pump/motor 8, and oil pipe 10 links to each other with change-over valve 9, and some energy storages 11 link to each other with oil pipe 10, link to each other by sequence valve 12 between the energy storage 11, by pass valve 13 is installed on the oil pipe pipeline, and first travel switch 15 is installed on accelerating throttle pedal 14, and second travel switch 17 is installed on brake pedal 16.
Groundwork process of the present invention is as follows:
1, brake snub: when automobile is wanted brake snub, depress pedal of clutch earlier, power-transfer clutch 2 disconnects, driving engine 1 power and change-speed box 3 disconnect, depress brake pedal 16, travel switch 17, power-transfer clutch 5 is closed, the energy-storage type hydraulic braking system for automobile is engaged, and automobile kinetic energy is from wheel 6 to drive axle 7, change-speed box 3 passes to the power taking window gear 4 of change-speed box 3, and power taking window gear 4 is rotated, driving hydraulic pump/motor 8 rotates, travel switch 17 the electric position, change-over valve 9 left side that makes simultaneously connects, with hydraulic oil by pump by oil pipe 10 to energy storage 11 fuel feeding, reclaim the energy of brake.Fully use this part energy stored to prepare when starting next time.The quantity of energy storage 11 increases and decreases according to the car weight amount.Sequence valve 12 is installed between energy storage, hydraulic oil is full of in order one by one.When the vehicle length downhill braking, when hydraulic oil was full of in the energy storage, by pass valve 13 was opened, hydraulic oil by by pass valve to the fuel tank overflow.
