Description

Automobile pedal buffer

Technical field

This utility model belongs to vehicle mechanical and controls class field, specifically, is automobile pedal buffer.

Technical background

Vehicle is with a varied topography, especially many at some hills, area landforms, the injury of vehicle and personnel all can be caused owing to bringing to a halt or suddenly stepping on the gas, it is susceptible to vehicle accident, which results in vehicle be in operation needs continuous down hill braking, the super casualty caused because of brake system failure is continuously increased.And in Traffic Systems, due to vehicle launch, braking frequently, brake often, causes the aging quickening of public transit vehicle brakes, the braking of public transit vehicle and drive system expend serious.

At present, automobile buffer mainly has hydraulic buffer and current vortex buffer etc. several, hydraulic buffer has forced heat radiation function, it is applicable to travel in non-plains region, need the vehicle of long-time braking, but it is expensive, it is currently used primarily in the domestic high gear passenger vehicle of assembling and import parts assembles passenger vehicle.Current vortex buffer does not possess forced heat radiation function, can burn even initiation vehicle spontaneous combustion fire accident when caloric value exceedes its thermal capacity maximum, thus be only applicable to the vehicle travelled in plains region, the short time brakes.There is a kind of independent role capsule buffer in gas pedal at present, but throttle can only be had certain effect by it, it is impossible to solve clutch pedal, brake pedal and the cushioning effect of gas pedal.

It was verified that buffer is the preferred plan solving vehicle the problems referred to above.In city vehicle, buffer can extend the life-span of brakes 4-8 times, effectively reduces vehicle maintenance, cost of business operation.In coach, for steep slope topography, buffer can effectively alleviate the heat fading of the hot generation of hub for vehicle wheel causes braking ability to decline, and tire is easily layered the disadvantage causing Earlier cracking, makes vehicle travel safer, reduces the generation of vehicle accident.

Utility model content

In order to solve in prior art, be difficult to reset when wherein one or two pedal damages, step on wrong pedal because of error and cause the problem of accident, this utility model provides automobile pedal buffer.

Automobile pedal buffer, includes in the mutual fluid-through chamber that " king " font is connected,

The top of three sap cavities is equipped with retainer ring, and retainer ring is connected to clutch, brake and throttle, and retainer ring is connected to upper rubber piston by push rod；The lower section of three sap cavities is equipped with the fixed screw of band, and pedal is fixed on automobile chassis through fixed screw, and fixed screw is connected to lower rubber piston by spring；Cavity between upper rubber piston and lower rubber piston is hydraulic fluid chamber, is full of hydraulic oil in hydraulic fluid chamber.

Further, retainer ring is that the work being articulated and connected is connected with the connected mode of clutch, brake and throttle.

Further, fixed screw is that the work being articulated and connected is connected with the connected mode of pedal.

Further, spring is cylindrical compression spring.

Further, pedal, push rod, the material of retainer ring are rustless steel.

Compared with prior art, the utility model has the advantages that:

1. this utility model uses the interaction that the resiliency of spring and hydraulic pressure are interconnected, and better controls over clutch pedal, brake pedal and gas pedal so that the pedal of automobile can rise smoothly or land, and is beneficial to the safety of driving；And the vehicle accident that can effectively prevent in these three pedal any one damage and produce, makes vehicle smooth ride, the frequency that reduction accident occurs；

2. this utility model simple in construction, practical, weight alleviates further, volume reduces further, low cost, and application prospect is extensive, it is simple to existing vehicle refitting is promoted.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

In figure, 1, the fixed screw of band, 2, pedal, 3, spring, 4, lower rubber piston, 5, hard tube, 6, hydraulic fluid chamber, 7, upper rubber piston, 8, push rod, 9, retainer ring.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments herein is described in detail, but the multitude of different ways that the application can be defined by the claims and cover is implemented.The accompanying drawing of the part constituting the application is used for providing further understanding of the present application, and the schematic description and description of the application is used for explaining the application, is not intended that the improper restriction to the application.

Automobile pedal buffer, includes in the mutual fluid-through chamber that " king " font is connected.

The top of three sap cavities is equipped with retainer ring 9, and the top of retainer ring 9 is connected to clutch, brake and throttle, and retainer ring 9 is that the work being articulated and connected is connected with the connected mode of clutch, brake and throttle.The lower section of retainer ring 9 is connected to rubber piston 7 by push rod 8 respectively, and upper rubber piston 7 has good sealing.

The lower section of three sap cavities is equipped with the fixed screw 1 of band, and pedal 2 is fixed on automobile chassis through fixed screw 1.Fixed screw 1 is that the work being articulated and connected is connected with the connected mode of pedal 2.Fixed screw 1 is connected to lower rubber piston 4 by spring 3, and lower rubber piston 4 has good sealing.

Cavity between upper rubber piston 7 and lower rubber piston 4 is hydraulic fluid chamber 6, in hydraulic fluid chamber 6 be full of hydraulic oil, upper rubber piston 7 and lower rubber piston 4 by hydraulic oil seal in hydraulic fluid chamber 6.
