A thrust rod testing machine

Abstract

The invention discloses a thrust rod testing machine, which comprises a machine body. A boom 1 and a boom 2 are arranged at two ends of the body respectively. The thrust rod is clamped between the first boom and the second boom. A vertical push cylinder is installed, and the lower end of the vertical push cylinder is hinged with clamping claws, and the clamping claws are provided with a clamping gap matched with the thrust rod. The thrust rod is clamped between the first boom and the second boom, and the thrust rod is clamped on the jaws and located in the clamping gap. The first and second booms are flipped and swayed to simulate the force applied to the thrust rod, and the vertical push cylinder The output shaft expands and contracts, and the up and down push and pull force is applied to the thrust rod to simulate the vibration force generated during the driving process of the vehicle, which is consistent with the actual operating conditions and reduces the error of the experimental simulation results.

Description

technical field [0001] The invention relates to thrust rod testing equipment, in particular to a thrust rod testing machine. Background technique [0002] Thrust rods are important components for heavy trucks and buses to connect the frame and axles and transmit longitudinal and lateral loads. The thrust rod is mainly composed of a head, a shaft and an elastic ball pin, and the two ends are connected together by a steel pipe through hot riveting, and have sufficient connection strength. In order to detect the service life and usage status of the thrust rod, an experimental device is usually required to conduct a simulation experiment on the thrust rod to detect the force and service life of the thrust rod. [0003] The Chinese patent whose notification number is CN2773652Y discloses a kind of vehicle thrust rod simulation experiment device, comprises frame body, has hydraulic drive device and control device on the frame body, and it has a power swing arm and a passive swing...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned simulation experiment device only simulates and detects the two torsion directions of the thrust rod, and the vehicle will vibrate up and down during actual driving, which will affect the use of the thrust rod. Therefore, the error of the experimental results of the above-mentioned simulation experiment device is relatively large
