The invention discloses a front axle master pin oil injection structure and a front axle assembly. The front axle master pin oil injection structure comprises a front axle, a steering knuckle and a master pin; the end of the main pin penetrates out of the front axle and forms a protruding part, and a shaft hole is formed in the steering knuckle; an assembly gap is formed between the shaft hole and the main pin, a drain valve and an oil cup are arranged on the steering knuckle, the drain valve comprises a pipe body, a plugging piece and an elastic piece, a first opening and a second opening are formed in the pipe body, and the plugging piece is arranged in the pipe body; the plugging piece can move between the first position located between the first opening and the second opening so that the first opening and the second opening can be disconnected and the second position located on the side, away from the first opening, of the second opening so that the first opening and the second opening can be communicated, and the elastic piece is used for pushing the plugging piece towards the first opening. When grease is injected into the assembly gap through an oil cup, a discharge valve is opened to discharge air and old grease in the assembly gap, and oil injection operation is facilitated.

    本发明公开了一种前桥主销注油结构及前桥总成,前桥主销注油结构包括前轴、转向节、主销;主销的端部由前轴穿出并形成一凸出部,转向节上设置有轴孔;轴孔与主销之间形成一装配间隙,转向节上设置排放阀、油杯,排放阀包括管体、封堵件、弹性件,管体上设置有第一开口、第二开口,封堵件置于管体内部,且该封堵件能够在位于第一开口和第二开口之间以使第一开口和第二开口断开的第一位置和位于第二开口远离第一开口一侧以使第一开口和第二开口导通的第二位置之间运动,弹性件用于将封堵件朝向第一开口顶推。本发明在在通过油杯向装配间隙内注入油脂时,使排放阀打开排出装配间隙内的空气以及旧的油脂,方便注油操作。
