The invention discloses a wear resistant mining truck rear suspension. The wear resistant mining truck rear suspension mainly consists of a piston rod, an oil seal frame, an outer cylinder barrel and a piston ring, wherein a bearing mounting hole A is formed in the head of the piston rod; the tail of the piston rod extends into the outer cylinder barrel, and is fixedly connected with the piston ring; a lubricant injecting port A communicated with the bearing mounting hole A is formed in the side surface of the head of the piston rod; an oil inlet hole A and an oil outlet hole A are formed in the head of the piston rod; an oil inlet hole B and an oil outlet hole B are formed in a rod body of the piston rod; a boss is arranged at the head of the outer cylinder barrel, and is provided with a lubricant injecting port B; and the lubricant injecting port B is communicated with a bearing mounting hole B in the head of the outer cylinder barrel. The wear resistant mining truck rear suspension is characterized in that a mounting groove is formed in the outer side wall of the piston ring; a wear resistant ring is mounted in the mounting groove; and the height H of the wear resistant ring is 181.5 mm. As the wear resistant ring is mounted on the side wall of the piston ring, the abrasion of the piston ring can be reduced, the damage of the piston ring due to abrasion is prevented, and the stability of the rear suspension is improved; and the wear resistant mining truck rear suspension is mainly used as a rear suspension of a mining truck.
Description
technical field [0001] The invention relates to the technical field of mining vehicles, in particular to a wear-resistant rear suspension of mining vehicles. Background technique [0002] The suspension of a mining vehicle is one of the important assemblies on a mining vehicle. The suspension is the connecting part between the frame and the axle or the wheel, and transmits the force between the ground and the car body, and the purpose is to slow down the impact load caused by the uneven road surface. [0003] The rear suspension of traditional mining vehicles is mainly composed of piston rod, oil seal frame, outer cylinder and piston ring. The head of the piston rod has a bearing installation hole A, and the tail extends into the outer cylinder and is fixedly connected with the piston ring. The side of the head of the piston rod has a lubricating oil injection port A connected to the bearing installation hole A, the head of the piston rod has an oil inlet hole A and an oil ...
