Abstract

The utility model discloses a U-shape beam-type damping bicycle frame, wherein, the main beam rod is a U-shape beam rod which is integrally connected with a front fork frame shaft sleeve, a keyboard shaft sleeve, a back flat fork frame and a back upper inclined fork frame forming the integrated structure frame; a spring base, which is integrally connected with the beam rod, is arranged at the middle beam section for the U-shaped main beam rod with the integrated structure frame; a saddle support beam which is formed by the plate-shaped spring is fixed on the spring base at one end; the saddle riser with a connection plate and a saddle mounting and locking hoop is fixed on the saddle support beam. The utility model has the advantages that the integrated structure frame for the assembling wheels and the sprocket drive structure and the saddle elastic support beam which is formed by a spring plate between the saddle effectively buffers and damps the bumping and the shock produced during running process, greatly decreasing bumping from the bicycle body upon human body.

Description

U type beam type damping bicycle stand

Technical field

The utility model relates to a kind of bicycle rack.

Background technology

The vehicle frame of the bicycle of existing the most widely used various structural shapes is rigid the connection with saddle, during driving the damping of human body is only depended on that saddle spring cushions, damping.Because saddle spring is harder, can not damping makes the rider feel very uncomfortable to human body effectively when car body jolts vibrations.The vibrations of jolting that car body produces when driving a vehicle in order to cushion effectively reduce the chatter effect of car body vibrations to human body, and people have carried out all improvement to cycle frame.These improve all at vehicle frame self damping and carry out, and saddle still is traditional rigid connection with vehicle frame.Because damping effect is not obvious, in addition or the manufacture craft trouble, make the accuracy requirement height, or the vehicle frame profile is attractive in appearance and be not widely adopted.

The utility model content

The purpose of this utility model provides a kind of can effectively cushion and the car body of the decaying vibrations of jolting produce the U type beam type damping bicycle stand of chatter effect to human body.

The purpose of this utility model realizes by following design.

The girder bar of U type beam type damping bicycle stand is a U type beam column.Chain drum axle sleeve, the end that front forked frame axle sleeve, the integral body that U type girder bar, integral body are connected U type girder bar front end is connected U type girder bar bottom is welded on that oblique crotch constitutes the integral structure frame on the other end is mutually permanently connected on the U type girder bar back chain stay frame, the back, the U type girder bar middle beam section of integral structure frame has the spring perch that has supporting leg with the whole bonded assembly of beam column, and an end of the Saddel receiver beam of being made by plate-shaped springs is connected and fixed on spring perch.The connecting panel other end that one end integral body is connected with band Saddel receiver beam hugging has saddle and the Saddel receiver standpipe of locking strap is installed is connected and fixed at the other end of Saddel receiver beam by connecting panel.

Between the assembling wheels of the U type beam type damping bicycle stand that the utility model provides, the integral structure frame of sprocket drive and saddle the elasticity Saddel receiver beam that spring plate is made is set, the vibrations of jolting to car body in the driving process can cushion and damping effectively, thereby have reduced the chatter effect that the car body vibrations produce human body greatly.

The specific embodiment

The girder bar (6) of U type beam type damping bicycle stand is a U type beam column.By U type girder bar, be welded on the welding front end front forked frame axle sleeve (7), be welded on chain drum axle sleeve (11), an end on U type girder bar bottom connecting panel (10), (16) and be welded on oblique crotch (13) formation integral structure frame on the other end is welded to each other on the U type girder bar back chain stay frame (12), the back.The U type girder bar middle beam section of integral structure frame has the spring perch that has supporting (9) (4) with the beam column welding, and an end that is pasted the folded Saddel receiver beam of making (15) by plate-shaped springs is locked on spring perch by fastener (5), (8).The cross section that one end is welded with band Saddel receiver beam hugging is

The Saddel receiver standpipe (2) that the connecting panel of type (3) other end has saddle installation locking strap (1) is locked at the other end of Saddel receiver beam by fastener (14) by connecting panel.

Claims

1, a kind of U type beam type damping bicycle stand, it is characterized in that the girder bar is a U type beam column, U type girder bar, integral body is connected the front forked frame axle sleeve of U type girder bar front end, integral body is connected the chain drum axle sleeve of U type girder bar bottom, one end is welded on the back chain stay frame that the other end is mutually permanently connected on the U type girder bar, oblique crotch constitutes the integral structure frame on the back, the U type girder bar middle beam section of integral structure frame has the spring perch that has supporting leg with the whole bonded assembly of beam column, one end of the Saddel receiver beam of being made by plate-shaped springs is connected and fixed on spring perch, and the connecting panel other end that an end integral body is connected with band Saddel receiver beam hugging has saddle and the Saddel receiver standpipe of locking strap is installed is connected and fixed at the other end of Saddel receiver beam by connecting panel.
