Problems solved by technology
The thrust rod of this kind of polyurethane sleeve cannot move freely during the car movement. It depends on the elasticity of polyurethane to adjust the direction of movement and force. The force between the two bridges is uneven and depends on polyurethane. The bearing strength is low and it is easy to wear , the joint is easily damaged, and the life of the thrust rod is short
and high manufacturing cost

The invention relates to a thrust bar joint, in particular to a thrust bar joint for heavy-duty vehicles. The thrust bar joint comprises a joint body (4) and a connection shaft (1) arranged in the joint body (4). The thrust bar joint is characterized in that a flexible body (7) is arranged in the space between the connection shaft (1) and the joint body (4). The characteristics of the flexible body can enable the connection shaft to be adjusted by corresponding angles no matter two bridges sway in horizontal direction or in vertical direction, thus alleviating the counter force of the vehicleto the thrust bar, preventing the connection from being damaged and protecting the connection shaft. The thrust bar joint has high bearing strength, abrasion resistance, and low manufacture and use cost.
Description
A thrust rod joint Technical field: The invention relates to a thrust rod joint, in particular to a thrust rod joint for a heavy-duty vehicle. Background technique: The thrust rods of commercial trucks such as Dongfeng and Jiefang in the prior art have two joint bodies, and connecting pieces are connected between the two joint bodies. The thrust rod of this kind of polyurethane sleeve cannot move freely during the car movement. It depends on the elasticity of polyurethane to adjust the direction of movement and force. The force between the two bridges is uneven and depends on polyurethane. The bearing strength is low and it is easy to wear , the joint is easily damaged, and the life of the thrust rod is short. And the manufacturing cost is high. This is the weak point that existing technology exists. Invention content: The purpose of the present invention is to provide a thrust rod joint with high bearing strength, wear resistance and low manufacturing cost in view o...
