Background technology
At present, the power-assisted of hydraulic braking system for automobile comes from vacuum booster, and the power-assisted effect is relevant with engine working conditions; The power-assisted effect is not very desirable; And owing to have the gap between each parts of brake system, air application time is longer, for braking safety bigger influence is arranged.
The utility model content
Its purpose of the utility model just is to provide a kind of energy wheel cylinder booster type hydraulic braking system for automobile, and vibrational energy that can the recovery section automobile is used for brake boost, and it is little to have a brake pedal force; Can reduce air application time; Characteristics simple in structure, easy to use, that cost is low.
The technical scheme that realizes above-mentioned purpose and take comprises vacuum booster, brake pedal and master brake cylinder; Also comprise shock absorber, shock absorber is a piston cylinder operator, and piston upper chamber is that fluid chamber cavity of resorption is the nitrogen chamber; The shock absorber upper end is provided with compression valve and rebound valve, and described compression valve connects fluid reservoir by the road, and rebound valve connects energy storage by the road; The energy storage outlet is provided with limiting valve and connects brake wheel cylinder through the electromagnetism check valve; Described brake pedal connects master brake cylinder through vacuum booster, and described master brake cylinder connects fluid reservoir, and connects brake wheel cylinder through load sensing valve.
The utility model compared with prior art, its advantage is.
1, can be the hydraulic pressure ability with the partial vibration Conversion of energy.
2, can reduce brake pedal force, reduce the driving fatigue degree.
3, shorten air application time, improve the automobile braking safety performance.
4, have simple in structure, easy to use, the characteristics that cost is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the utility model structural principle scheme drawing.
The specific embodiment
Also comprise shock absorber 2; Shock absorber 2 is a piston cylinder operator, and piston 3 epicoeles are that fluid chamber cavity of resorption is nitrogen chamber 4, and shock absorber 2 upper ends are provided with compression valve 1 and rebound valve 7; Described compression valve 1 connects fluid reservoir 10 by the road; Rebound valve 7 connects energy storage 6 by the road, and energy storage 6 outlets are provided with limiting valve 5 and connect brake wheel cylinder 8 through electromagnetism check valve 9, and described brake pedal 13 connects master brake cylinder 11 through vacuum booster 12; Described master brake cylinder 11 connects fluid reservoir 10, and connects brake wheel cylinder 8 through load sensing valve 22.
Described shock absorber is provided with four, and described energy storage is provided with four, and described brake wheel cylinder is provided with four.
Embodiment, as shown in the figure, comprise 4 shock absorbers, 4 energy storages, petrol storage tank, 4 brake wheel cylinders, 4 electromagnetism check valves, master brake cylinder, vacuum booster, brake pedal and load sensing valve.Shock absorber comprises compression valve and fuel feed hole, rebound valve and oil outlet, piston and nitrogen chamber; Energy storage is provided with limiting valve and fuel return hole; The electromagnetism check valve is controlled by brake pedal.The vibrational energy of described vibrational energy wheel cylinder booster type hydraulic braking system for automobile ability recovery section automobile is converted into hydraulic pressure and can be used for the automobile power brake; Reduce brake pedal force; Reduce the driving fatigue degree, shorten air application time, improve the automobile braking safety performance.
Work as automobile vibration; When shock absorber 2,16,21,26 is compressed when (wheel compresses suspension near vehicle frame); Piston 3 moves down, and the nitrogen chamber of compressing under it 4 raises its pressure, and fluid chamber, piston top volume strengthens; Oil pressure descends, and the fluid in the petrol storage tank 10 gets into the fluid chamber through fuel feed hole and compression valve 1.When suspension is in extension stroke (wheel leaves vehicle frame, shock absorber is elongated), move on the piston 3 fluid chamber volume is reduced, oil pressure raises, and compression valve 1 is closed, and fluid is through rebound valve and oil outlet 7, energy storage oil inlet entering energy storage 6,17,20,25.Along with oil pressure in the energy storage 6,17,20,25 raises, increased the fuel-displaced resistance of shock absorber, dumping force is further strengthened.High pressure nitrogen in the nitrogen chamber 4 of piston below can reduce the high-frequency vibration that produces when wheel runs into impulsive force, and helps to eliminate noise, and certain buffer action is arranged.
The high pressure oil from shock absorber 2,16,21,26 is accepted and stored to energy storage 6,17,20,25.When automobile needs braking; When chaufeur is stepped on brake pedal 13; Electromagnetism check valve 9,15,18,24 is opened, and the high pressure oils in the energy storage 6,17,20,25 get into brake wheel cylinders 8,14,19,23 via energy storage oil outlet pipe and electromagnetism check valve 9,15,18,24, also gets into brake wheel cylinder 8,14,19,23 from the oil of master brake cylinder 11 through load sensing valve 22; Impel each car side brake effect to produce braking force, car deceleration.Since energy storage 6,17,20,25 when being provided with near brake wheel cylinder 8,14,19,23, so before the master brake cylinder oil pressure raise, brake wheel cylinder 8,14,19,23 can build-up pressure, produces braking effect, thus the shortening air application time.When loosen the brake 13, the oil in the brake wheel cylinder 8,14,19,23 returns fluid reservoir 10 through load sensing valve 22, master brake cylinder 11. Energy storage 6,17,20,25 is provided with limiting valve 5 and oil return pipe, and when its in-to-in oil pressure reached specified value, surplus oil liquid returned petrol storage tank 10 through limiting valve 5 and oil return pipe.
