Description

Technical Field

[0001] The utility model relates to the technical field of thrust rods, in particular to a wear-resistant buffer type thrust rod assembly. Background Art

[0002] The thrust rod is mainly used in heavy-duty vehicles with single-axle or double-axle bridges of trucks or passenger cars, connecting the frame and the axle. Its main purpose is to overcome the problem that the steel plate and the first spring can only transmit vertical force and lateral force but cannot transmit traction, braking force and its corresponding reaction torque;

[0003] After searching, the applicant found that a Chinese patent disclosed "a rear thrust rod pin assembly", and its publication (announcement) number is "CN218266685U". This patent mainly adopts an integrated setting of the thrust rod pin and the fixing plate, which can facilitate the rapid assembly of the thrust rod. The threaded hole at the bottom of the thrust rod pin facilitates the screwing of the oil filling pipe thread and the injection of lubricating oil between the thrust rod and the thrust rod pin, thereby improving the lubrication effect and reducing wear. However, the device is not convenient for buffering when in use, which makes it easy to be damaged or broken when subjected to impact force. For this reason, we propose a wear-resistant buffering thrust rod assembly. Utility Model Content
