Five, the specific embodiment
Following with reference to accompanying drawing 1-11, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.
Trackless wireless electric vehicle brake includes combination air pump part, energy storage section, pipe section, control cock class part, and after the combination air pump partly was positioned at the electric car trailing wheel, energy storage section, pipe section, control cock class partly were distributed on the vehicle frame;
Combination air pump part, combination air pump assembly 7 drive inflation pump by electrical motor by belt and constitute, and the gas of output certain pressure is fixed on the body framwork; Energy storage section, form by four air receivers, look back the air receiver 2 that is respectively for propons braking usefulness from the place ahead on chassis, the air receiver 1 that supplies preceding door switch to use, air receiver 2 for back axle braking usefulness, for the air receiver 1 that the back door switch is used, air receiver 1, air receiver 2 are fixedly connected on the vehicle frame by air receiver anchor ear 5 and air receiver anchor ear support 6; Control cock class part comprises four-loop protection valve 3, blow off valve 4, master brake cylinder 33, dryer 15, rapid release valve 20, relay valve 30, pressure switch control cock;
Pipe section, air is via after making up air pump assembly 7, be pressurized to 8 bar pressures, via metal establishment flexible pipe 8 and bite type free flow coupling 9, enter and draw copper pipe 10, the heat in copper pipe in the pressurized air that temperature is higher distributes, air via copper pipe after dryer crossover sub 21 and taper thread end union elbow 27, enter dryer 15, in dryer, the agent absorption (seeing that C is to view) that is dried of airborne moisture and greasy dirt.Be divided into two-way through the air that purifies.Wherein one the tunnel via air dryer-regenerating tank joint 22, ferrule-type compression joint nut 23, cutting ferrule 24, lining 25 and nylon tube 26 enter regeneration storage tank 28, and be stored, when air pressure in the dryer surpasses the safe air pressure of regulation, gas in the regeneration storage tank 28 can spring back in the dryer, and the impurity in the desiccant is gone out dryer.Another road gas enters four-loop protection valve 3 via dryer crossover sub 21, taper thread end union elbow 19 and nylon tube 16, and in four-loop protection valve 3, gas is divided into four tunnel (seeing that B is to view).Between this four road gas, each road all is independent inflation, and wherein riches all the way gives birth to leakage can not influence other gas circuit, thereby guarantees the safety of driving.Each road gas enters an air receiver separately.
The air receiver of using for forward and backward bridge (30L) inserts master brake cylinder 33 (seeing the II enlarged view), gas storage socket joint master brake cylinder 33 admission ports of back axle, gas storage socket joint master brake cylinder 33 another admission ports of propons by a nylon tube respectively.When chaufeur tramped with one's feet brake pedal 32, the stroke on its first rank was the electric braking part, at this moment utilized to motor to add counter-current, made motor that counter-rotational trend be arranged, and played the auxiliary braking effect.The second rank stroke has been connected the air extractor duct of master brake cylinder 33, and gas is carried (seeing that D is to view) via the relay valve 30 of nylon tube road direction back axle direction.Gas through taper thread right-angle tee adaptor union 31 and bite type rubber hose coupling assembly, enters back axle braking locellus via relay valve 30, thereby has realized the compressed air brake of back axle.Another air extractor duct gas is carried (seeing that A is to view) via nylon tube to the rapid release valve 20 of propons direction, gas via rapid release valve 20 after, divide by two-way to enter propons braking locellus, thereby realize the compressed air brake of propons through bite type circular cone free flow coupling and lining and nylon tube.
The air receiver 2 of propons and pressure switch control cock 34 link to each other by pipeline, and when the air pressure of air receiver was lower than the regulation atmospheric pressure value, the combination air pump was started working; When the air pressure of air receiver was higher than regulation air pressure, the combination air pump quit work, and realizes the automatic guidance of pressure variation.
The trackless wireless electric vehicle brake of present embodiment, thus can be according to the energy savings of pressure variation automatic guidance combination air pump.
