Abstract
The utility model discloses a new type of hydraulic pressure braking device on the front wheel of the motorbikes, comprising a petrol storage tank provided with a hydraulic cylinder, which is provided with a manual control hydraulic piston touching a handle-like braking rod. The petrol storage tank is connected by the front hydraulic oil pipe with the front hydraulic brake; the pedal braking plate is connected with the pedal hydraulic cylinder provided with a pedal hydraulic piston touching the pedal braking plate; the front hydraulic oil pipe is provided with a tee hydraulic valve; a piston is arranged on the tee hydraulic valve, and one division of the tee hydraulic valve is connected with the pedal hydraulic cylinder by the bake hydraulic oil pipe. The utility model is able to brake the front wheel just with the baking rod controlled by the right hand or to brake the front wheel while the pedal plate brakes the back wheel, making the riding more secure and the whole braking process quicker and more convenient. The utility model has the advantages of simple structure, high safety and application, good braking effect, convenience to operate and low cost.
Description
Technical field the utility model relates to a kind of brake equipment of motor bike, relate to a kind of front-wheel of motor bike that makes specifically at glancing impact, can carry out independent brake by holding lever connection, can form the motor cycle front-wheel hydraulic brake system of forward and backward wheel synchronous braking brake by the control of pedal brake plate again.
Background technology is very many in the owning amount of China's motor bike, no matter be in the metropolis, it still is in small and medium-sized cities and the rural area, motor bike is very general as the vehicle, because motor bike is fast as vehicle speed, volume is little, and is with low cost, it is little to take up room, so the owning amount of China's motor bike is very high.But the accident rate of motor bike is very high, one of them reason is exactly that the braking of motor bike exists certain problem, present known motorcycle brake device all is the brake mode of forward and backward wheel split braking, that is: front-wheel is by holding lever connection control, and trailing wheel is by foot feed.This brake mode tends to occur following phenomenon in actual braking procedure: at first, be throttle gate because of right hand major control, holding lever connection generally speaking is not in and waits to hold under the state, when running into extraordinary circumstances and need emergency braking, because the high concentration or the driving habit of navigating mate spirit, often only use the stretcher braking and ignored manual control braking front-wheel.Like this with regard to produced have only trailing wheel to be braked and front-wheel do not have the braking phenomenon, wheel is relative with ground-surface friction drag to be reduced, and has increased the braking inertia distance of car body, and the safety factor of driving is obviously reduced.Secondly, since the braking of front and back wheel be by two fully independently system control respectively, to vehicle body braking the time, be difficult to reach synchronous relatively and stress equalization, particularly when the speed of a motor vehicle is higher relatively, when front-wheel braking, occurs turning over phenomenon before the car body during greater than the braking force of rear wheel early than trailing wheel braking or front vehicle wheel braking force easily.
It is a kind of simple in structure that the summary of the invention the purpose of this utility model is to provide, safe and practical, good braking effect, easy to use, motor cycle front-wheel hydraulic brake system with low cost, it not only can utilize lever connection that front-wheel is carried out independent brake with the right hand, also can utilize stretcher when rear wheel is braked, front-wheel to be carried out the one braking, to improve the braking effect in the driving process, make the car load brake operating simplify more and effectively control before braking the improper car body that causes and turn over.
The purpose of this utility model is to realize by following technical scheme:
A kind of motor cycle front-wheel hydraulic brake system, comprise petrol storage tank, in this petrol storage tank hydraulic ram is set, install and hold the contacted manual hydraulic piston of lever connection in this hydraulic ram, said petrol storage tank connects the front-wheel hydraulic brake by preceding hydraulic oil pipe, the pedal brake plate connects foot-operated hydraulic ram, should in the foot-operated hydraulic ram the foot-operated hydraulic piston that contacts with the pedal brake plate be installed, its structural feature is: a hydraulic three-way valve is installed in the middle of the hydraulic oil pipe before said, piston is installed in this hydraulic three-way valve, and another of said hydraulic three-way valve branch road connects foot-operated hydraulic ram by the back hydraulic oil pipe.Foot-operated hydraulic piston is fixed in pedal brake plate below, when holding lever connection manual hydraulic piston applied application force, manual hydraulic piston reach, hydraulic oil in the hydraulic ram is compressed, the pressure that produces passes to piston in the hydraulic three-way valve by preceding hydraulic oil pipe, and promotion piston reach, when closing hydraulic three-way valve branch road opening to hydraulic ram in hydraulic oil compress, the pressure that produces is delivered to the front-wheel hydraulic brake that is connected with front-wheel by preceding hydraulic oil pipe, front vehicle wheel is braked, reached the purpose of manual independent brake front vehicle wheel; Unclamp and hold lever connection, each one is returned to the home position under the effect of hydraulic brake tension force, and the branch road opening of hydraulic three-way valve is opened again; When rear wheel being braked with the pedal brake plate, the foot-operated hydraulic piston that is fixed in pedal brake plate below is subjected to application force equally and moves forward, hydraulic oil in the foot-operated hydraulic ram is compressed, the pressure that produces is directly delivered on the front-wheel hydraulic brake of front vehicle wheel by back hydraulic oil pipe, the anterior fluid cylinder of hydraulic three-way valve, front vehicle wheel is produced braking, thereby only reach the purpose that just can brake simultaneously front and back wheel with the pedal brake plate, make whole brake operating program easier, quick.
Be connected oil circuit communicating pipe between said foot-operated hydraulic ram and the said petrol storage tank.Be provided with oil circuit communicating pipe between oil tank and the foot-operated hydraulic piston cylinder body, to guarantee conveying and hydraulic return oil in foot-operated piston.
Connecting an adjustable bolt in said foot-operated hydraulic piston outer end, is said pedal brake plate above the adjustable bolt.By reconcile adjustable bolt make the braking starting time of front-wheel slightly be later than rear wheel the braking starting time, make the size of the suffered braking force of two-wheeled reach balanced, with overcome car body because of brake improper occur before turn over.
Advantage of the present utility model is: the utility model not only can utilize lever connection that front-wheel is carried out independent brake with the right hand, also can utilize stretcher when rear wheel is braked, front-wheel to be carried out the one braking, thereby effectively improve the braking effect in the driving process, the car load brake operating is simplified more, and effectively control is turned over before braking the improper car body that causes, improved braking effect, make driving more safe and reliable, only reach the purpose that just can brake simultaneously front and back wheel with the pedal brake plate, make whole brake operating program easier, fast.The utility model is simple in structure, and is safe and practical, and good braking effect is easy to use, and is with low cost.
