Integrated triangular thrust rod assembly

Abstract

The invention discloses an integrated triangular thrust rod assembly. The thrust rod assembly comprises a triangular thrust rod, a spacing bush, a rubber sealing ring I, a rubber vulcanized joint bearing assembly, an elastic check ring, a thrust rod support, a rubber sealing ring II, a metal joint bearing assembly, a pressing plate, a nut II, a sealing cover and a grease nozzle. A triangular thrust rod is a flat triangular structure formed through integral forging, a middle portion of the triangular thrust rod is a triangular hollow structure, a rod body portion of the triangular thrust rodis an ''I''-shaped structure, and cylindrical cavities are arranged in three end portions of the triangular thrust rod. The thrust rod support, the rubber sealing ring II, the metal joint bearing assembly, the pressing plate, the nut II, the sealing cover and the grease nozzle are arranged in a cavity in a top end. Inner structures of two side end cavities are the same, and each side end cavity comprises the rubber vulcanization joint bearing assembly, the rubber sealing ring I, the spacing bush and the elastic check ring. The assembly is simple and reliable in structure, extremely high in safety coefficient and convenient to mount and dismount.

Description

technical field [0001] The invention relates to an integral triangular thrust rod assembly for a balanced suspension system, which belongs to the field of heavy-duty commercial vehicle suspension. Background technique [0002] The rear suspension system of heavy-duty commercial vehicles generally adopts a balanced suspension. The balanced suspension system is very important for the vehicle. It connects the axle assembly and the frame. It plays the role of starting force, braking force and lateral force transmission, while the transmission of longitudinal and lateral force depends on the thrust rod assembly arranged between the frame and the axle. According to the force requirements, the balanced suspension system generally arranges six thrust rod assemblies, including two on the upper side and four on the lower side. [0003] In the traditional integral balanced suspension, the upper two thrust rods are straight rods, and the lower four straight rods only play the role of l...

Problems solved by technology

However, for super-heavy vehicles, when driving for a long time under harsh road conditions, the traditional V-shaped thrust rod is not suitable for the transmission of longitudinal force and the lateral positioning of the axle, and the ball head often falls out, the V-push rod breaks, and the V-push connecting bolt often occurs. A series of failures such as looseness greatly increase the failure rate of the vehicle, reduce the utilization rate of the vehicle, and cause a lot of trouble to the user
