Description
Technical field
What the present invention relates to is a kind of acceleration pedal, the specifically acceleration pedal of automobile.
Background technology
Along with science and technology and the improving constantly of people's living standard, automobile and battery-driven car more and more universal.Acceleration pedal is as the vitals that can not lack, and its performance plays vital effect to the safety of car load and efficiency.Traditional acceleration pedal does not nearly all accelerate curvature restriction, makes chaufeur when maloperation, easily causes the accident.In addition, rational acceleration chart can reduce driving engine energy consumption and exhaust pollutant discharge greatly.Application number is the patent " car ACCEL Anti-mis-stepping method " of 201110263172.4, this patent just invent to prevent from stepping on by mistake in conjunction with the acceleration pedal of simple function of electronics with machinery, complicated and be difficult to promote.Application number is the patent " for selecting control setup and the method for acceleration pedal drag characteristics curve " of 201010299345.3, and this patent is the method for the adaptive damping acceleration pedal of pure electronics, complex structure, and must combine with automobile ECU, is difficult to promote.
Summary of the invention
The object of the present invention is to provide a kind of mechanical variable damping acceleration pedal adopting mechanical method to solve error stepping on accelerator pedal and mutative damp acceleration chart function.
The object of the present invention is achieved like this:
A kind of mechanical variable damping of the present invention acceleration pedal, it is characterized in that: comprise stretcher, plunger, plunger sleeve, fluid reservoir, plunger is arranged in plunger sleeve and also can moves along plunger sleeve, working medium is equipped with in space between plunger and plunger sleeve, plunger at one end is connected with stretcher by kinge-joint knot, between stretcher and plunger sleeve, retracing spring is installed, 3 pipe interfaces are set bottom plunger sleeve, first pipe interface is communicated with fluid reservoir by check valve, second pipe interface is communicated with fluid reservoir by brake activation valve with adjustable opening valve, 3rd pipe interface connects brake activation valve by adjustable safe valve.
The present invention can also comprise:
1, plunger sleeve is provided with the support kinge-joint knot of the bearing surface for joint pin plug sleeve and pillar stiffener plug sleeve, makes plunger and plunger sleeve trampling and follow rotation with stretcher, after the length of plunger sleeve ensures that stretcher is stepped on to die, plunger can not touch plunger sleeve.
2, described working medium comprises hydraulic oil, machine oil, air.
Advantage of the present invention is: the present invention adopts mechanical method to solve the function of error stepping on accelerator pedal and mutative damp acceleration chart, and structure is simple, practical, economical and practical, has good market outlook.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Composition graphs 1, the present invention by the following technical solutions: mechanical variable damping acceleration pedal is mainly made up of stretcher 1, kinge-joint knot 2, retracing spring 3, plunger sleeve 4, plunger 5, check valve 6, adjustable safe valve 13, brake activation valve 12, pipeline 7, working medium 9, fluid reservoir 10, adjustable opening valve 11.Hinged with kinge-joint knot 2 between stretcher 1 and plunger 5, plunger 5 and plunger sleeve 4 are a set of precision pairs, retracing spring 3 is housed between plunger sleeve 4 and stretcher 1, the length of plunger sleeve 4 should ensure that stretcher 1 is stepped on back-plunger 5 to die and also do not touched bottom plunger sleeve 4, also be hinged with kinge-joint knot 8 with bearing surface bottom plunger sleeve 4, make plunger 5 and plunger sleeve 4 can trampling and follow rotation with stretcher 1.Have 3 pipe interfaces bottom plunger sleeve 4, one connects a check valve 6, then utilizes pipeline 7 to be connected to fluid reservoir 10, and such working medium 9 just can only unidirectionally be passed through.One connects adjustable safe valve 13, and safety valve 13 other end is connected with brake activation valve 12 control end, and brake activation valve 12 is often opened.Another connect an adjustable opening valve 11 and one often open brake activation valve 12, same recycling pipeline is connected to fluid reservoir 10, and the aperture changing valve just can change the damping force characteristics of stretcher, realizes the damping change of acceleration pedal.The working medium 9 of fluid reservoir 10 can use hydraulic oil, machine oil, air etc., specifically selects according to collective's application requirements reasonable selection.
Under normal circumstances, chaufeur should when using this acceleration pedal 1 first, just regulate applicable oneself adjustable opening valve 11 and adjustable safe valve 13, can according to the best acceleration chart of driving engine, optimum discharge performance and when stepping on by mistake safety-valve open the factors such as pressure and regulate.When chaufeur normally steps on acceleration stretcher 1, the arched arm of stretcher 1 promotes plunger 4 by kinge-joint knot 2 and moves down, extruding working medium 9, certain pressure is formed in plunger sleeve 4, check valve 6 ends, and working medium 9 can only by often opening brake activation valve 12 and variable degree valve 11 7 flows to fluid reservoir 10 by the road, and the aperture of valve 11 just determines the flow of working medium 9, so the descending process of plunger 5 is just restricted, thus limit the movement rate of stretcher 1.Change the damping coefficient that valve 11 aperture also just changes stretcher 1.If chaufeur has in case of emergency stepped on stretcher 1 by mistake, so piston bush 4 internal pressure increases severely, adjustable safe valve 13 will be opened, hydraulic oil opens brake activation valve 12 by safety valve 13, brake activation valve 11 is closed, 5, piston can not continue descending, and at this moment chaufeur just can be appreciated that and oneself stepped on pedal 1 wrong, thus can reduce the probability of occurrence of accident.When chaufeur decontrols stretcher 1, retracing spring 3 just pushes stretcher 1 and gets back to initial position, in reseting procedure, plunger 5 moves up, thus make to form negative pressure in plunger sleeve 4, check valve 6 is opened, and working medium 9 can enter rapidly plunger sleeve 4, stretcher 1 is resetted with the fastest speed, realizes trampling continuously of stretcher 1.
