Abstract
The invention provides an intelligent safety system capable of controlling a throttle and a brake of an automobile synchronously and relates to the technical field of synchronous control over the throttle and the brake of the automobile. The intelligent safety system comprises a wire pull disc, a throttle foot bar, a throttle buffer device, a clutch device and a touch control switch. The wire pull disc is connected with the throttle foot bar through a rotating shaft. The rotating shaft is sleeved with a reset torsional spring and connected with the throttle foot bar. The front end of the throttle foot bar is connected with a throttle footstep. The throttle buffer device comprises a damping hydraulic main pump, a first hydraulic sub pump and a second hydraulic sub pump. The damping hydraulic main pump is connected with the hydraulic sub pumps through hydraulic pipes. According to the intelligent safety system, the throttle and the brake of the automobile can be controlled synchronously; when the automobile is controlled normally, the opening and closing range of the throttle can be controlled by treading the throttle; under the emergency condition, when the throttle is used as the brake by mistake, the system can start the throttle buffer device so that the wire pull disc can be separated from the clutch device, oil supply is stopped, automatic brake is achieved, and thus serious consequences brought by error operation are eliminated.
Description
Technical field
The present invention relates to gas brake synchronous control technique field, particularly relate to a kind of gas, brake synchro control intelligent safety system.
Background technology
New hand driver is new hand's female driver especially, and the tragedy by mistake stepped on by phenomenon of taking throttle as brake, its miserable degree makes each driver's palpitaition.Can why throttle again and again be treated as brake and step on? this is relevant with the structure of automobile.How to avoid the mistake that phenomenon of taking throttle as brake seems rudimentary like this, conscientiously need the problem solved really at present.
Summary of the invention
The object of the present invention is to provide a kind of gas, brake synchro control intelligent safety system, to solve the problems of the technologies described above.

In emergency circumstances, when throttle uses when use brake by chaufeur, driver generally can accelerator pedal too hard, at this moment the pressure that flow regulating valve is subject to meets or exceeds locking force value, flow regulating valve cuts out, Das Gaspedal is felt to step on motionless (resistance is larger), now, hydraulic separate supplementary biography is delivered to the first hydraulic shunt pump and the second hydraulic shunt pump by hydraulic pipe by the pressure of Das Gaspedal, the wheelcylinder piston bar that hydraulic oil promotes the first hydraulic shunt pump is protruding, prize clutch arm, one end of clutch arm is inwardly pressed by the wheelcylinder piston bar of the first hydraulic shunt pump, then the other end of clutch arm tilts, clutch is exited from clutch hole.Throttle patching panel gets back to initial condition, not fuel feeding.One end that the arm of clutch is simultaneously pressed inwardly touches touch switch, and touch switch starts alarm; The wheelcylinder piston bar that hydraulic oil promotes the second hydraulic shunt pump is protruding, prizes one end of laborsaving lever, and pressure is passed to the push rod of braking mechanism vacuum booster pump by laborsaving lever, and braking mechanism vacuum booster pump obtains the braking force of brake.
The invention has the beneficial effects as follows:
The present invention can realize synchro control to the throttle of automobile and brake, during normal manipulation automobile, trample throttle and can control throttle size, in case of emergency, miss by throttle when using with brake, system will start throttle shock absorber, and cable quadrant is separated with clutch, stop control lever also realizes self-actuating brake, thus the serious consequence that elimination maloperation brings.
