Abstract

The invention discloses a suspension coupling test testing stand, comprising an under carriage, a portal frame body, an upper support, a straight line guidance light pillar, a counterweight shoe plate, a straight line bearing, a shaking table, various U-shaped clamps, a force transducer, a displacement sensor, a speed transmitter, an accelerometer, a data acquisition system, a radial translating roller push rod disc cam mechanism, a belt drive secondary deceleration power transmission mechanism, a frequency converter, etc. The frequency converter adjusts the rotational speed of a motor; the secondary deceleration power transmission mechanism drives a cam to rotate; the roller push rod disc cam mechanism is guided by a trapezoid mounting rack to push the shaking table. The suspension coupling test testing stand has the characteristics of simple structure, convenient maintenance, large test scope, numerous objects and high innovation practical value, employs a novel cam mechanism for driving, provides large load excitation, replaces cams of different line types to realize sine excitations and random excitations of different amplitudes and frequencies, and can perform coupling tests between a steel plate spring, a helical spring, an air spring and a damper.

Description

technical field

[0001] The invention relates to a test bench for performance matching of an automobile elastic element and a shock absorber, which is suitable for a leaf spring suspension, a coil spring suspension and an air spring suspension. More specifically, it relates to an automobile quarter suspension matching test bench. Background technique

[0002] Suspension is one of the important assemblies of modern automobiles, it can transmit all forces and moments acting between the wheel and the frame or body; ease the impact of the road surface, attenuate the vibration, and ensure the ride comfort; It has ideal motion characteristics, ensures handling stability, etc. At present, the performance matching of automobile suspension mainly includes bench test and road real vehicle test. As for the bench test, for now, the quarter suspension matching test bench is mainly aimed at the trolley, or the performance test of a single elastic element or the performance test of the sh...
