The present invention discloses a front bridge main pin structure system, including: the front bridge body and the main pin are interference fit, the seal pad is set at the upper end of the steering knuckle, the seal ring is set between the front bridge body and the steering joint for sealing the gap between the front bridge body and the steering knuckle, the lower end cover is set at the lower end of the steering knuckle, and the adjustment cushion is set at the end. The lower end cover and the main pin are used to adjust the gap between the end cover and the main pin. The sealing pad is used to seal the gap between the front axle and the lower part of the steering knuckle. The seal ring is used to seal the gap between the end cover and the steering knuckle; the pin is articulated with the steering knuckle, and the main pin is located on the top side, the main pin is located at the upper end, and the main pin is located on the upper side of the upper end. The wide part is located at the lower end cover side, the main pin's step position is located at the connection between the main pin and the front axle; the weight of the vehicle is on the front bridge body by suspension. The front bridge body transfers the force to the main pin through the steps on the main pin. The lower end contact with the end cover and transfer the gravity to the lower end cover, and the lower end cover is connected with the steering knuckle. Connect with the bolt.

一种前桥主销结构系统
本专利技术涉及重卡前桥技术,特别涉及一种前桥主销结构系统。
技术介绍
图1所示为现有前桥主销结构系统示意图,如图1所示,在前桥转向节与主销配合过程中,目前市场上主流的匹配方式是,前桥体通过主销与转向节相连和推力轴承相连,整车载荷通过悬架作用在前桥体上,前桥体分别作用在两端推力轴承上,推力轴承作用在转向节上,并通过转向节传递到车轮上。目前这种推力轴承的主销结构由于整车前桥重量全部作用于推力轴承上,且重型自卸车的工况较复杂,这样就会导致推力轴承损坏。由于目前多数主销和前桥体配合是过盈配合,这样会给更换轴承带来麻烦,维修性较差。
技术实现思路
本专利技术的目的在于提供一种前桥主销结构系统,用于解决上述现有技术的问题。本专利技术一种前桥主销结构系统,其中,包括:密封环、前桥体、转向节、主销、上端盖、下端盖、调整垫片、密封圈以及密封垫;前桥体和主销是过盈配合,密封垫设置在转向节上端,密封环设置在前桥体和转向节之间,用于密封前桥体和转向节之间的缝隙,下端盖设置在转向节下端,调整垫片设置在下端盖与主销之间,用于调整端盖与主销之间的间隙,密封垫用于密封前桥体与转向节下部的间隙,密封圈用于密封端盖与转向节的缝隙;销与转向节铰接,通过轴承相对转动,主销成台阶结构,主销窄部位于上端盖侧,主销的宽部位于下端盖侧,主销的台阶位置位于,主销与前桥体的连接处;整车重量通过悬挂作用在前桥体上,前桥体通过主销上的台阶将作用力传递到主销上,主销下端与端盖接触并将重力传递到下端盖上,而下端盖与转向节通过螺栓进行连接,并将重力作用到转向节上。根据本专利技术的前桥主销结构系统的一 ...
