Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] The present invention adopts frequency conversion speed regulation, drives the crank connecting rod mechanism through the clutch to generate mechanical excitation, and forces the shock absorber to reciprocate and stretch to do work to realize the testing purpose. The upper end of the shock absorber is connected to a tension and pressure sensor, and the damping force value of the shock absorber is detected through the measurement and control system to judge whether the shock absorber is qualified.

[0012] Such as figure 1 As shown, the present invention is a double-station dynamometer, two detection stations are installed on one test bench, and two shock absorbers can be detected simultaneously. At the same time, because the working principle of each detection station is the same and works independently, this dynamometer can also be simplified...

Abstract

The invention relates to a double-station and multispeed indicator of a vehicle damper. The double-station and multispeed indicator of the vehicle damper is characterized in that two stations are disposed side by side on the same test bed, wherein each station comprises a variable frequency motor; the output end of the variable frequency motor is connected to a crank connecting rod mechanism by a variable-speed motor and a clutch; the upper end of the crank connecting rod mechanism is connected to a clamp seat; the clamp seat comprises two slide bars and a pressing cover clamping frame and a damper clamping frame supported between the two slide bars; the bottom end of the clamp seat is provided with a pushing oil cylinder for pushing the damper; the rod part of the damper is connected to a tension-compression sensor which is disposed on a lifting cross beam in a hanging manner; the lifting cross beam is controlled by a lifting oil cylinder. A crank sensor is connected to the crank connecting rod mechanism. The indicator can vary a plurality of excitation velocities by a measurement and control system, and can be provided with a pressing cover, so that the damper rod is not pulled away when the damper is in an experiment, thereby precisely detecting the damping property of the damper in front of a close cover.

Description

technical field [0001] The invention relates to a tension-compression test equipment, in particular to a multi-speed tension-compression dynamometer for automobile shock absorbers with two stations. Background technique [0002] The dynamometer is one of the important equipment for testing the performance of the automobile shock absorber during the production process. Especially before the shock absorber is sealed or welded, only by testing whether its performance meets the indicators required by the technical specifications can the quality and reliable performance of the sealed or welded shock absorber be guaranteed. Most of the dynamometers used in the early stage were single-station dynamometers, and they were still spring torsion bar detection and manual locking. The detection error rate was high, the production efficiency was low, and the manual operation was intensive. It could only be detected at one speed point and could not fully reflect question.
