Description

一种V型汽车推力杆
技术领域
本实用新型涉及一种汽车悬挂架部件,特别是一种V型汽车推力杆。
背景技术
V型汽车推力杆主要用在重型卡车的平衡悬挂装置中,用来连接后桥和车架并起减震作用。目前国外的V型汽车推力杆,其V型杆头内主要为带座销与关节轴承的配合,由于V型杆头、带座销、关节轴承都是金属材料,造成V型汽车推力杆弹性不够,缓解冲击载荷能力较差;带座销与关节轴承的配合要求尺寸精度较高,增加了加工和采购成本,其在国内的售价高达1800元人民币;此外还存在装配困难,关节轴承损坏后整个V型汽车推力杆就报废等问题。中国专利200720182176.9所述V型汽车推力杆,其V型杆头内采用自润滑向心关节轴承,轴承内圈采用金属材料,外圈采用具有自润滑性能的高强度工程塑料,该V型汽车推力杆较目前国外的V型汽车推力杆有技术进步,但仍然部分存在目前国外V型汽车推力杆的不足之处。
发明内容
本实用新型的目的在于:提供一种V型汽车推力杆,它可以克服现有技术的不足,使产品弹性好,装配简单,满足使用条件且售价低。
本实用新型的目的是通过以下途径来实现的:一种V型汽车推力杆,包括推力杆胶芯、杆身、推力杆头、V型杆头、外油封圈、油封、垫圈、卡环、上端盖、螺栓、压盖、轴承内圈、轴承外圈、内油封圈、带座销,其结构特点为:V型杆头内安装了自润滑关节轴承,轴承外圈和轴承内圈均采用具有自润滑性能的高强度尼龙,轴承内圈与带座销配合。
与现有技术相比,本实用新型的一种V型汽车推力杆,V型杆头内采用材料为高强度尼龙的自润滑关节轴承,轴承内圈与带座销配合,装配简单,成本低,每只售价仅800元;高强度尼龙轴承弹性好,缓解冲击载荷能力较强;高强度尼龙轴承具有自润滑功能,工作时无需添加润滑油、润滑脂,具有较长的使用寿命;高强度尼龙轴承重量轻,使汽车更节能;此外高强度尼龙轴承损坏后可以随时更换,节约了V型汽车推力杆的使用成本。
附图说明
图1是本实用新型的结构示意图;
图2是图1的A向结构示意图;
图3是图2的B-B剖面示意图。
