Problems solved by technology

[0003] The inventor finds through long-term observation and research that the V-type automobile thrust rod often adopts threaded connection, arc welding, and hot riveting to connect the thrust rod and the automobile frame. Poor, serious waste of energy
② Only the local strength of the V-shaped thrust rod is increased. The connection methods at both ends of the V-shaped thrust rod are inconsistent, and the inconsistent strength is prone to damage
③The threaded connection method needs to add buckles, and the threads are affected by the machining accuracy and the clamping torque of the buckles, so the thread slippage and loosening failure are prone to occur
④The arc welding connection is limited by the material and welding process level, the product quality is unstable, and the welding is not firm
⑤Hot riveting connection with low assembly precision and poor product quality

Abstract

The invention relates to an automobile thrust rod, which comprises a V-shaped thrust rod formed by a rod body. The V-shaped thrust rod is provided with a connection end and a free end, and the connection end and the free end of the thrust rod are provided with frame connection pins perpendicular to the axial direction of the rod body. According to the invention, the product quality is improved, the production cost is lowered, and the phase precision of the thrust rod and an axle and the phase precision of the thrust rod and a frame are improved.

Description

technical field [0001] The invention relates to a component of an automobile suspension system, in particular to an automobile thrust rod. Background technique [0002] The V-type thrust rod of the rear suspension of heavy-duty vehicles is a connecting device, an important stressed part that connects the axle and the frame to transmit load and moment. The V-shaped automotive thrust rod connects the axle and the frame, and is widely used in air suspension, rubber suspension, suspension when disconnected. Therefore, it is necessary to provide an improved automobile thrust rod to reduce the weight of the vehicle, reduce the manufacturing cost, improve the reliability and the torsion and tensile resistance of the thrust rod. [0003] The inventor finds through long-term observation and research that the V-type automobile thrust rod often adopts threaded connection, arc welding, and hot riveting to connect the thrust rod and the automobile frame. Poor, energy waste is serious. ...
