Abstract
The utility model discloses a brake apparatus for an automobile, which relates to a safety apparatus for an automobile. The apparatus uses a short-distance brake pedal installed at the left side of the clutch pedal in the driver's cab and a zigzag cam installed on the shaft liner of the brake pedal to operate a controller. The controller makes the executor release high gear and put into reverse gear; the clutch pedal and the brake pedal are slightly uplifted for the rider to step on the accelerator; therefore, wheels are reversed in site for a short time in order to decrease the forward slip inertia of the automobile, shorten brake distance and improve the traffic safety.
Description
Urgent braking device of automobile relates to the safety device of running.
Automobile is brought into play its vital function as a kind of transport facility day by day in social production, life.When automobile travelled on highway, speed per hour was generally at 80 kilometers or higher, and speed per hour is 50 kilometers when travelling in the city.When particularly travelling in the city, because the crossing is many, vehicle is wasteful, bicycle and pedestrian's dealing are many, make road conditions become complicated.Under emergency, must emergency braking in case have an accident.Brake system on the automobile is compression air brake and hydraulic braking at present, and after the driver stepped on brake pedal, because the effect of inertia of running car, even the complete stall of wheel, automobile still will slide a segment distance forward.According to GB GB7258-87 self-propelled vehicle safe in operation condition regulation, total mass is 4.5 tons a compact car, and when speed per hour was 30 kilometers, the distance of emergency braking should be less than 7.5 meters, and running deviation value should be less than 80 millimeters.Even in this predetermined distance, because the inertia of uncontrollable automobile still personal injury and car accident might take place.
The purpose of this utility model provides a kind of automobile short range brake device, makes automotive operation more reliable and secure.
Using the main purpose of urgent braking device of automobile is under the situation of emergency braking, the realization automobile is extractd high speed gear rapidly, is changed and hang reverse, wheel under engine drive, realize the friction of counter-rotating of short duration original place, thereby reduce the advancing slip inertia of automobile, realization short range braking, and extract reverse gear at short notice, be convenient to automobile start.
Urgent braking device of automobile is that a short range brake pedal is installed on the indoor plate washer of vehicle drive again, and pedal is contained in the left side of car clutch pedal, and the serration cam of unidirectional rotation is housed on the axle sleeve of pedal arm.By pedal and the cam-actuated controller of sawtooth, and by car gear shifting actr, the open the throttle wide actr of controller control and the actr that original power-transfer clutch in the automobile, the little journey of brake pedal are lifted.Controller, actr can adopt fluid pressure type or electrical equipment formula.When adopting fluid pressure type, controller is a Hydraulic Pump, and the push rod of Hydraulic Pump is adjustable; Actr is a hydraulic actuating cylinder, and the stroke of hydraulic actuating cylinder is also adjustable, and hydraulic actuating cylinder is connected with oil pipe with Hydraulic Pump.When adopting the electrical equipment formula, controller is a travel switch, and actr is to have the adjustable electromagnet of push rod, travel switch and electromagnet electricity consumption wire joint.The sequence of operation of Hydraulic Pump and travel switch is determined by the serration cam.
Accompanying drawing is for adopting fluid pressure type urgent braking device of automobile embodiment scheme drawing.
