The tie rod assembly is a key component in the automobile steering system and an important component to ensure the safe driving of the automobile.

The tie rod assembly is a key component in the automobile steering system and an important component to ensure the safe driving of the automobile. For example, a horizontal tie rod left and right joint body assembly is disclosed, which includes a ball pin, a joint body and a rod body integrally formed with the joint body. The ball pin includes a ball head and a club integrally formed with the ball head. The center of the joint body is provided with a central opening. The upper side of the central opening is necks and the top is chamfered, the ball seat is an annular ball seat with upper and lower symmetrical inner spherical surfaces on the inner ring, and the top and bottom end faces of the elastic rubber ball seat are horizontal; the cover is clamped at the bottom of the central opening, the elastic rubber ball seat is embedded in the central opening above the cover, and the horizontal end face at the bottom is fitted with the cover; the upper and lower symmetrical inner spherical surfaces of the elastic rubber ball seat are adapted to the radian of the spherical surface of the ball head; the ball head is arranged in the spherical cavity formed by the elastic rubber ball seat and the joint body, and the bottom of the ball head is cut to form a horizontal end face and has a certain gap with the cover. It uses an elastic rubber ball seat in the joint body as a ball seat used in conjunction with the ball head, so that it can effectively support and buffer, thereby reducing the contact area between the ball seat and the ball head and reducing wear.

Further, in order to prevent dust from entering between the ball head and the joint body and affecting the movement of the ball head, the horizontal pull rod left and right joint body assembly is also provided with a dust cover between the joint body and the club of the ball pin to prevent dust. One end of the dust cover is fixed on the joint body, but the other end of the dust cover is sleeved outside the club of the ball pin and is held outside the club only by its own elastic force. When the ball pin swings, the dust cover will be stretched and deformed, which will easily cause the dust cover to shift on the club and create a gap between the two, resulting in poor dust-proof effect.
