Abstract

一种转轴式避震自行车车把,在不改变车把的原型情况下,增加了转轴避震功能。自行车轮经把立管传来的振动经转轴套10传递弹性支架上的弹性垫7再经把斜管5传递于把横管上,起到了避震缓冲作用,本实用新型成本低,抗颠簸性能好,抗冲击能力强。

Description

一种转轴式避震车把
本实用新型涉及的是一种弹力避震车把,具体地讲是自行车车把缓冲器。
目前,已出现了各种避震车把,如液压避震车把等,但由于结构复杂,成本高等问题,在商品转化中难以普及推广。本实用新型在满足一般避震要求的情况,设计了最简单的转轴式避震车把,为本人申报的ZL92219172.7一种弹力减振车架配套之用。
为了达到上述目的,本实用新型是这样实现的:它是由把横管1,把横接头2,把横螺丝3,把横螺母4,把斜管5,把立管6,弹性垫7,弹性支架8,固定轴套9,活动轴套10,活动轴11,轴螺母12等组成。
附图说明:
图1为车把结构示意图;
图2A-A为车把俯视剖视图。
附图图面说明:
把横管1,把横接头2,把横螺丝3,把横螺母4,把斜管5,把立管6,弹性垫7,弹性支架8,固定轴套9,活动轴套10,活动轴11,轴螺母12。
下面以附图为实施例进一步说明如下:
取标准把立管6一只,在上端距25mm处用Φ15铣刀铣出半圆孔,将已做好的固定轴套用氩弧焊焊牢,然后焊上弹性支架8,弹性支架有δ=2.5mm的铁板折弯而成,也可以用铁专门锻造而成。把斜管5采用直径Φ28mm铁管,壁厚2.2铁管经模具冲压加工而成。将把横接头2,把斜管5焊接在一起。单件做好后进行组装。将硫化成型的橡胶弹性垫7(弹性垫也可以用聚氨酯等弹性材料制造)插在弹性支架8上,再将活动轴套10套入固定轴套9内,活动轴套10与固定轴套精度要高,以木锤敲入为宜。活动轴套10长度尺寸比固定轴套9略长0.05-1.5mm,以保证把斜管5的活动间隙。将把斜管5套入弹性垫7与活动套10孔对齐,将活动轴11穿入活动轴套内,两面将轴螺母12拧紧。将把横管1穿入把横接头2,将把螺丝3穿入把横接头2,拧紧把横螺母4。一只转轴式避震车把制作完毕。
