Working process of the present utility model is as follows:
Referring to Fig. 1 and Fig. 2, Fig. 1 also is the embodiment that the utility model connects the pneumatic brake system.When needing deceleration, parking in the running car, the driver depresses brake pedal, oil pressure in the brake operation oil pipe 12 of automobile is risen, the piston 62 that promotes in the maneuvering valve 6 moves, and when pore 64 was connected with two pipe interfaces at valve body 61 middle parts, the air pressure of former car braking inflator 14 moved down the piston 52 in the control cock 5, make pressure rising in the oil cylinder 31, promote piston 32 and move, and promote thrust baring, platen, friction lining and move to left, brake coupling is in engagement state.At this moment take-off 2 obtains power to drive air pump axle 43 from output shaft of gear-box 11.Air pump axle 43 drives piston 41, and the power cam valve closes and opens mechanism simultaneously, makes to open a certain valve when piston 41 from first dead center when lower dead point moves, and air is passed through the commutation air valve 8 suction cylinders 40 of pipeline 17 and 5 unlatchings of Be Controlled valve; When piston 41 from lower dead point when first dead center moves, these valve closure, another valve opening, piston 41 is pressed into accumulation of energy pneumatic tube 7 with the air in the cylinder 40 by pipeline 18 and commutation air valve 8.So move in circles, air constantly is pressed into accumulation of energy pneumatic tube 7, and the tube internal gas pressure constantly raises, up to driver's loosen the brake, piston 61 in the maneuvering valve 6 is return, the opening of pore 65 leads to the pipeline of control cock 5, the opening of Pneumatic pipe cleaner air passing hole 65 on the end face of piston 61 is wherein let out in the atmosphere, thereby the piston 52 of control cock 5 is retreated, cause oil pressure decline in the oil cylinder 31, move behind the piston 32, air pump axle 43 separates with take-off 2, and air pump shuts down.Simultaneously, the pressure decay of control cock 5 recovers closed conditions by pipeline cause commutating air valve 8, to keep the pressure in the accumulation of energy pneumatic tube 7.So far, finished accumulation of energy process of the present utility model, made brake snub kinetic energy be converted into pressurized air elastic potential energy in the accumulation of energy pneumatic tube 7.When vehicle starting, the driver depresses Das Gaspedal, power control oil pipe 13 internal pressures are risen, the piston 62 of another maneuvering valve 6 that is attached thereto moves right, pore 64 is connected the tracheae between accumulation of energy pneumatic tube 7 and the control cock 5, piston 52 moves in the anticyclonic pressure promotion control cock 5 in the accumulation of energy pneumatic tube 7, cause oil cylinder 31 and the pipeline oil pressure that passes to commutation air valve 8 to rise, brake coupling is in on-state, air valve 8 commutations that commutate are simultaneously opened, be that the valve of former connection atmosphere changes and passes to accumulation of energy pneumatic tube 7, the valve of former connection accumulation of energy pneumatic tube 7 is connected to atmosphere.And the valve switch of cylinder 40 order does not change, and when piston 41 moved from the first dead center to the lower dead point, the former valve that connects atmosphere, now connects accumulation of energy pneumatic tube 7 was opened, and high pressure gas are pushed into lower dead point with piston 41; When piston 41 when lower dead point moves to first dead center, formerly connect accumulation of energy pneumatic tube 7, now connect the valve opening of atmosphere, discharge gases in the cylinder 40, piston 41 is got back to first dead center under effect of inertias such as flywheel.So move in circles, compressed air-driven energy storing brake air pump 4 runnings in the accumulation of energy pneumatic tube 7, and, be converted into the power that propelling vehicle advances by 1 rotation of take-off 2 drive output shaft of gear-box.Because this extra power has been arranged, consumption of fuel reduces, reduces component wear and exhaust gas discharging in the time of just making vehicle starting.
Fig. 2 is the embodiment of the utility model on vacuum servo formula brake system automobile.Wherein, connect in the maneuvering valve 6 of brake operation oil pipe 12, the pipeline that connected braking pressure tube 14 originally changes into and connects former car lubricating oil oil main line 15, and the valve body 61 right side mouths of pipe are connected former car oil return pipe 16 to oil pan tray.Glancing impact by the piston in the pressure control valve in the lubricating oil oil main line 15 5 52, and then engages air pump axle 43 and take-off or separates.The maneuvering valve 6 that connects power control oil pipe 13 both can connect accumulation of energy pneumatic tube 7, can connect oil main line 15 and oil return pipe 16 in the same manner again, with the variation of air pressure or oil pressure control cock 5 was controlled.
Fig. 5 has the embodiment of vacuum cylinder for the utility model.Vacuum cylinder 9 of tracheae 17 reconfigurations at former connection atmosphere.In braking accumulation of energy process, energy storing brake air pump 4 constantly from vacuum cylinder 9 extracting air be compressed in the accumulation of energy pneumatic tube 7; When the pressurized air elastic potential energy drove 4 actings of energy storing brake air pump when starting, the pressurized air in the accumulation of energy pneumatic tube 7 was got back to again in the vacuum cylinder 9, and when air pressure in two tubes was approaching or equal, accumulation of energy air pump 4 shut down, and energy discharges with conversion process and finishes.
Fig. 5 also is the embodiment that the utility model has a differential pressure control valve (DPCV).The structure of differential pressure control valve (DPCV) 92 and control cock 5 are basic identical, just the left end at its piston is provided with a pressure reduction control stalk 91, its left end joins with piston 62 in the maneuvering valve 6 that is connected power control oil pipe 13, accumulation of energy pneumatic tube 7 is connected with the valve body of pressure reduction control stalk 91 1 sides, and atmosphere is connected on differential pressure control valve (DPCV) 92 right sides.When vehicle starting, accumulation of energy pneumatic tube 7 engages brake coupling by maneuvering valve 6 and control cock 5, and the commutation of commutation air valve is opened, and air pump is started working.Reduction along with air pressure in the accumulation of energy pneumatic tube 7, piston in the differential pressure control valve (DPCV) 42 is moved to the left under the effect of spring, and the piston 62 that promotes in the maneuvering valve 6 moves to left, little after certain numerical value at air pressure, gas circuit between accumulation of energy pneumatic tube 7 and the control cock 5 is disconnected and release pressure in the control cock 5, and then energy storing brake air pump 4 is separated with take-off 2, finish energy and discharge and the process that transforms work done.Differential pressure control valve (DPCV) 92 plays a part a pressure sensor.
The utility model design is ingenious, rational in infrastructure, and reliable operation has following superiority:
1, the kinetic energy that loses in the time of effectively storing automobile brake or descending, and will It is converted into the power that automobile advances again.
2, energy savings reduces automobile fuel consumption.
3, reduce the automobile component wear.
4, reduce toxic emission, protected environment.
