Abstract
The utility model discloses an automobile slope auxiliary starting device, which is a slope parking control device for realizing automatic clutching or automatic speed varying improvement of an automobile which is provided with a hand-operated speed-changer. The automobile slope auxiliary starting device comprises a direct current dynamo speed reduction motor, a cutoff valve, a one-way valve and the like. An actuating mechanism is arranged in an automatic clutching or automatic speed varying general apparatus for taking the function of slope auxiliary starting, with the characteristics of simple and reasonable structure, only need of stepping on the gas during slope starting, simplified operating procedures, and high safety.
Description
One, technical field
The utility model belongs to the brake of motor-driven vehicle technical field, especially relates to the sloping road start assisting device that a kind of self-propelled vehicle to the configuration hand-operated transmission is implemented automatic clutch or automatic speed changing transformation.
Two, background technology
Present self-propelled vehicle for hand gear, at slope starting, require chaufeur that consummate operative technique is arranged, because chaufeur left foot clutch this moment, the right crus of diaphragm throttle, the brake of loosing one's grip of left hand bearing circle, the right hand, operational motion will cooperate just rightly, just can start to walk smoothly, otherwise can cause saunter car or engine off backward, thereby need the control step of simplifying slope starting badly, make things convenient for chaufeur to drive.
Three, technical scheme
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of simple and reasonable, slope starting only needs step on the accelerator, the step that simplifies the operation, safe self-propelled vehicle slope road start assisting device.
The purpose of this utility model is to realize like this, a kind of self-propelled vehicle slope road start assisting device, form by valve body and motor, be characterized in that motor is connected with worm screw is coaxial in valve body, worm and wheel connects, worm gear and sensor disk are fixed in the shutoff valve rotating shaft, the stop valve rotating shaft is provided with oil sealing, the shutoff valve rotating shaft is provided with penetrating rotating shaft oilhole, the circumference that valve body is close to shutoff valve rotating shaft rotating shaft oilhole is provided with intake vent and exit passageway, intake vent and exit passageway respectively with valve body on the brake pump interface be connected with the brake oil cylinder interface, intake vent and exit passageway also are communicated with by branched bottom and check valve.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts reducing motor, stop valve, check valve and pipeline are formed, be installed in the middle of the brake hydraulic pipeline, when self-propelled vehicle is positioned at sloping road foot brake, machine operation makes the stop valve oilhole, and disconnection is connected with exit passageway with intake vent, motor quits work, can not return brake pump to the brake fluid that brake oil cylinder transmits energy this moment, but brake pump still can be carried brake fluid to oil cylinder by check valve and branched bottom, during starting, driver's releasing of brake stretcher went in the time period of step on the accelerator, car keeps braking state, the car of can not sauntering backward, when the pedal of stepping on the throttle, power-transfer clutch in conjunction with the time, motor is worked again, make intake vent and go out the building passage and be communicated with by the rotating shaft oilhole, motor quits work, and the brake oil cylinder oil pressure is removed, brake is unclamped, and the self-propelled vehicle starting is advanced.
Four, description of drawings
Below in conjunction with drawings and Examples the utility model is described in further details.
Fig. 1 is this practical a kind of structural representation.
Fig. 2 is the birds-eye view of Fig. 1.
Five, specific embodiments
When using the utility model, brake pump interface 10 of the present utility model is connected with brake pump, brake oil cylinder interface 11 is connected with brake oil cylinder and gets final product, during brake, motor 14 work, shutoff valve rotating shaft 2 rotations make rotating shaft oilhole 13 and intake vent 7, exit passageway 8 leaves, and makes passage 7,8 block, motor 14 quits work, this moment, brake fluid can be from branched bottom 9 through check valve 3 access passages 8, can not reverse backflow, and releasing of brake, motor 14 work shutoff valve rotating shafts 2 are rotated, rotating shaft oilhole 13 and intake vent 7, exit passageway 8 is communicated with, and connects passage 7,8, motor 14 quits work.
