Abstract

本实用新型是一种轮胎与车辆轮毂轴头紧固连接用的钩头型轮胎螺栓。它包含有带有花键的螺栓体和与螺栓体成一体的螺栓头,螺栓头内底面上有一个与轮毂轴头上的环形槽相匹配的倒钩。使用时螺栓头的倒钩嵌入轮毂轴头上的环形槽,从而大大增加其定位强度,使用过程中不会损坏轮毂轴头的花键,甚至已损坏花键的轮毂轴头仍能继续使用,提高轮毂轴头使用寿命。

Description

钩头型轮胎螺栓
本实用新型涉及一种轮胎与车辆轮毂轴头紧固连接用的轮胎螺栓,特别是一种钩头型轮胎螺栓。
众所周知,大型轮胎与轮毂轴头紧固连接均采用带花键的轮胎螺栓,螺栓穿过轮毂轴头后由螺母拧紧,而螺栓后段上的花键与轮毂轴头的花键孔匹配,这样在拧紧螺母时螺栓不会跟转,从而达到一定拧紧力。这种轮胎螺栓仅靠花键与轮毂轴头定位,其定位强度不足,在使用过程中多次装拆,常出现轮毂轴头花键孔的花键强度硬度比螺栓花键强度硬度差而损坏,而不能继续使用。
本实用新型的目的在于提供一种钩头型轮胎螺栓,能与轮毂轴头有较大的定位强度,使用过程中不会损坏轮毂轴头的花键,甚至已损坏花键的轮毂轴头仍能继续使用。
为达到上述目的,本实用新型采用下述技术方案:本实用新型与现有技术一样包含有带有花键的螺栓体和与螺栓体成一体的螺栓头。其特点是螺栓头内底面上有一个与轮毂轴头上的环形槽相匹配的倒钩。在使用过程中,螺栓头的倒钩正好嵌入轮毂轴头上原有的环形槽内,从而大大增加轮胎螺栓与轮毂轴头的定位强度。
本实用新型与现有技术相比较,具有如下显而易见的优点:由于本实用新型采用的轮胎螺栓,保留原有的花键,而将螺栓头设计成有倒钩的螺栓头,螺栓头的倒钩正好嵌入轮毂轴头上原有的环形槽内,从而大大加强轮胎螺栓与轮毂轴头的定位强度,不会损坏轮毂轴头的花键,甚至已损坏花键的轮毂轴头仍能继续使用,延长轮毂轴头使用寿命。
附图的图面说明如下:
图1是本实用新型一个实施例的结构示意图。
图2是图1中A向局部视图。
图3是图1示例钩头型轮胎螺栓与轮毂轴头待安装状态的立体示意图。
本实用新型的一个最佳实施方案是:参见图1和图3,本钩头型轮胎螺栓包含有带有花键2的螺栓体1和与螺栓体1成一体的螺栓头3,螺栓头3内底面上有一个与轮毂轴头5上的环形槽7相匹配的倒钩4。参见图1、图2和图3,螺栓头3为方形,其内底面上的倒钩4为长条形凸块。使用时,钩头型轮胎螺栓插入轮毂轴头5的花键孔6内,并使螺栓头3内底面上的倒钩4嵌入轮毂轴头5的环形槽7内,然后在伸出花键孔6的螺栓上拧上螺母。
