Description

The shock-damping structure of motor vehicle pedal

Technical field

The present invention relates to the shock-damping structure of a kind of pedal, particularly a kind of motor vehicle pedal.

Background technology

The step of traditional motor bike back occupant generally is by the outwardly directed pipe fitting in vehicle body both sides; Overlap rubber sleeve on the pipe fitting; Rubber coating plays the effect that increases step area and vibration damping, but the not enough 40mm of the external diameter of rubber coating is very little with the area of contact of pin; Can only play a supporting role to the pin of back occupant, the comfort of back occupant pin is low.

In order to improve this situation, released a kind of big shelf of motor bike on the market, the left and right side lower end of big shelf is connected with the big pedal that back occupant uses, and big pedal has the pedal skeleton and the pedal of tubulose, and pedal can be shelved whole pin, and traveling comfort is high.This back step skeleton is the annular frame structure, and the loop of back step skeleton is welded by hollow tubular, and when motorcycle driving, the back step vibration is bigger, and the oscillation frequency of back step and vehicle frame is approaching, and causing easily resonance influences traveling comfort.Need be connected with big shelf to big pedal, material requested is many, and productive costs is high; And influence the appearance and modeling of motor bike and the problem of design diversity, and the applicant has designed a kind of back step of motor bike, and back step connects to ground through the inboard journal stirrup of pedal skeleton loop; It is high to have solved the big pedal productive costs of back shelf, influences the appearance and modeling of motor bike and the problem of design diversity, but because pedal is a cantilever design; Make the bigger problem of original big pedal vibration further worsen; Thereby, need a kind of shock-damping structure that is applicable to two kinds of big pedals of design, improve the traveling comfort of leg rest.

Summary of the invention

In order to overcome the deficiency of prior art, the purpose of this invention is to provide a kind of shock-damping structure of motor vehicle pedal, the vibrations of back step when the reduction self-propelled vehicle starts, the traveling comfort of raising back occupant leg rest.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of shock-damping structure of motor vehicle pedal comprises the pedal skeleton, and said pedal skeleton is the framed structure with two long limits and two minor faces, long limit wherein and long limit, and minor face and minor face are relative in twos, and a long limit is provided with counterweight therein.

As the further improvement of technique scheme, the said first long limit is the hollow tubular near frame sides, and the said first long limit is provided with said counterweight on the relative second long limit, and counterweight is arranged on the second long limit in the outer part of pedal skeleton, effectively damping.

Further, said counterweight is arranged on middle part, the second long limit; Said counterweight can be divided into two sections, is separately positioned on the both sides, middle part on the second long limit, and perhaps counterweight can also be divided into more than two sections, evenly is arranged on the second long limit; Said counterweight also is arranged on the second long both ends, limit and extends to the end of said two minor faces.

The invention has the beneficial effects as follows: the shock-damping structure of the design's motor vehicle pedal increases counterweight on the pedal skeleton; Change the natural frequency of pedal skeleton; Make the natural frequency of pedal skeleton different with the vehicle frame excitation frequency; Can not form resonance, effectively reduce pedal skeleton excitation amplitude from vehicle frame when motor-driven vehicle going, improve foot-operated traveling comfort.

As the further improvement of technique scheme, the part on the said second long limit except counterweight is the arc semicanal of hollow tubular or lower opening.

As the further improvement of technique scheme, said minor face is the arc semicanal of hollow tubular or lower opening.

As the further improvement of technique scheme, the solid rate of said counterweight is 70%-100%.Preferably, counterweight is that solid rate is 100% metal shaft part.

Further improvement as technique scheme; The said first long limit is provided with the connection journal stirrup that is used to connect vehicle frame; On vehicle frame, wherein the first long limit is in the inboard near vehicle frame to bolt through connecting journal stirrup with the pedal skeletal fixation, and the second relative long limit is in the outside.
