Abstract

本发明属汽车零部件，具体涉及一种汽车后桥限位拉杆。其特征是吊耳侧孔内设有螺套，穿钉拉杆一端设钉帽位于吊耳侧孔内，另一端由螺套中孔穿出与吊耳螺纹连接，在穿钉拉杆上设有与其螺纹连接的弹簧调整螺帽，弹簧调整螺帽与螺套之间的穿钉拉杆上设有弹簧。具有不易产生定性形性弯曲，在正常行驶时保证桥与桥之间的平行和各桥轮胎行一线，能提高轮胎使用寿命的优点。

Description

汽车后桥限位拉杆
技术领域：本发明属汽车零部件，具体涉及一种汽车后桥限位拉杆。 
背景技术：现有多桥汽车后桥限位拉杆是由拉杆两端上设有左右吊耳构成，左右吊耳之间设有连接机构，此连接机构是由弹簧套和穿钉拉杆组成，弹簧位于弹簧套内，其缺点是，弹簧的直径受弹簧套尺寸的限制，弹性不好，易产生定形性弯曲，不能保证在正常行驶时桥与桥之间的平行和各桥轮胎行一线，增加了行车阻力，加重对轮胎的磨损。 
发明内容：本发明的目的是提供一种结构简单、不易产生定形性弯曲，在正常行驶时保证桥与桥之间的平行和各桥轮胎行一线的汽车后桥限位垃杆。 
本发明的技术方案是：一种汽车后桥限位拉杆，在左右吊耳内设衬套，在左右吊耳之间设连接机构，连接机构是由弹簧和穿钉拉杆组成，其特征是在吊耳侧孔内设有螺套，穿钉拉杆一端设钉帽位于左吊耳侧孔内，另一端由螺套中孔穿出与右吊耳螺纹连接，在穿钉拉杆上设有与其螺纹连接的弹簧调整螺帽，弹簧调整螺帽与螺套之间的穿钉拉杆上设有弹簧。 
为了阻止灰尘进入左吊耳侧孔内，在穿钉垃杆和螺套之间设密封圈。 
为了提高穿钉拉杆使用寿命，增强穿钉拉杆和螺套之间的润滑，在螺套和左吊耳对应位置上设黄油嘴。 
由于采用上述技术方案，弹簧是套装在穿钉拉杆外圆上的，在汽车转弯时，不能产生定形性弯曲，能保证桥与桥之间的标准位置，因而具有不易产生定形性弯曲，在正常行驶时保证桥与桥之间的平行和各桥轮胎行一线，能提高轮胎使用寿命的优点。 
附图说明：以下结合附图和具体实施例来对本发明的技术方案做详细说明。附图是本发明的结构示意图。 
具体实施方式：参考附图，一种汽车后桥限位拉杆，在左右吊耳内设衬套2，在左右吊耳1、8之间设连接机构，连接机构是由弹簧5和穿钉拉杆6组成，左吊耳1侧孔内设有螺套3，穿钉拉杆6一端设钉帽位于左吊耳1侧孔内，另一端由螺套3中孔穿出与右吊耳8螺纹连接，在穿钉拉杆6上设有与其螺纹连接的弹簧调整螺帽7，弹簧调整螺帽7与螺套3之间的穿钉拉杆6上设有弹簧5。为了阻止灰尘进入左吊耳侧孔内，在穿钉拉杆6和螺套3之间设密封圈4。为提高穿钉拉杆使用寿命，增强穿钉拉杆和螺套之间的润滑，在螺套3和左吊耳1对应位置上设黄油嘴9。
