Vehicle Suspension System Performance Testing Platform

Abstract

The invention discloses an automobile suspension system performance testing platform, which comprises: a foundation pit, which is rectangular and has an area larger than the projected area of ​​a vehicle to be inspected on a horizontal plane; a sinking groove is opened in the middle of the foundation pit; In the groove, the output shaft of each motor is connected with the input shaft of a bevel gearbox, the output shaft of each bevel gearbox is connected with the input end of an electromagnetic clutch, and the output end of the electromagnetic clutch is connected with a reciprocating screw rod, each The reciprocating screw is provided with a sliding block that matches the reciprocating screw; four oscillating shafts are hinged on the bottom of the foundation pit, each oscillating shaft is located on the axis of a reciprocating screw, and each oscillating shaft is connected to the sliding block on the corresponding reciprocating screw. Connecting rods are arranged between the blocks to form a rocker slider mechanism, and an upward swinging rod is hinged at the joint between each swinging shaft and the connecting rod through a pin, and the end of the swinging rod is connected with a pressure sensor and a bearing plate. The invention overcomes the problem that the multi-axis articulated suspension detection table in the prior art cannot be driven.

Description

technical field [0001] The invention relates to the field of automobile performance testing equipment. More specifically, the present invention relates to a performance testing platform of an automobile suspension system. Background technique [0002] Car suspension is one of the important assemblies of a car, which elastically connects the frame (or body) with the axle (or wheel). Its main task is to transmit all the forces and moments acting between the wheels and the frame (or body); ease the impact load transmitted to the frame (or body) from the road, attenuate the vibration of the bearing system caused by it, and ensure the safety of the car. Ride comfort: to ensure that the wheels have ideal movement characteristics when the road is uneven and the load changes, to ensure the stability of the car's operation, and to enable the car to obtain high-speed driving capabilities. Therefore, the technical condition and working performance of the suspension have an important ...

Problems solved by technology

[0003] Existing automobile suspension testers generally include motors, energy storage flywheels, eccentric wheels, springs, and detection plates. The natural frequency of the suspension device resonates, but this structure has relatively large noise and serious wear of the eccentric wheel. Therefore, part of the testing platform adopts a multi-axis articulated suspension testing platform. However, there is a problem in the technical solution in this patent: that is, the actual motion track of the hinged end of the swing shaft 4 and the swing rod 6 is arc-shaped, and the highest point and the lowest point of the motion track are in the vertical direction. The height difference, and the movement of the hinged end of the swing shaft 4 and the swing rod 6 is the double-piston cylinder 9 that reciprocates in the horizontal direction. Therefore, in actual use, it is completely impossible for the double-piston cylinder 9 to drive the swing rod 6. Motion, in order to solve this problem, it is necessary to propose a new technical scheme of multi-axis articulated suspension test bench
