Embodiment Construction

[0030] The car 1 / 4 suspension test bench, (such as figure 1 Shown) is composed of three parts: simulated vehicle body, guiding device (1) and vibrating table.

[0031] Simulated body (such as Figure 5 Shown) is made up of upper bracket (201), lower bracket (2) and counterweight (203). The upper support (201) is n-shaped, and an axle is arranged in the middle position above. The lower support (2) is n-shaped, and there is a hole in the middle position above, and the counterweight (204) is fixed symmetrically on both sides, and the upper support (201) is fixed above, and the shaft on the upper support (201) and the lower support (2 ) above the hole is coaxial, and the center of gravity of the simulated vehicle body is on the lower axis of the hole on the lower support (2).

[0032] The guiding device (1) is made up of four columns and two groups of bar systems that limit the forward and backward motion and left and right motion of the simulated vehicle body. Four uprights a...

Abstract

The invention discloses a 1 / 4 suspension laboratory table for an automobile. The 1 / 4 suspension laboratory table consists of three parts including a simulated car body, a guiding device (1) and a vibration table, wherein the simulated car body consists of an upper support (201), a lower support (2) and a counter weight (203); and the guiding device (1) consists of four upright posts and two groupsof rod systems which can define front-back motion and left-right motion of the simulated car body; vibrating excitation of wheels through road surfaces is simulated by the vibration table, and the simulation is carried out in a way of dividing into two layers, and the two layers are mutually overlapped.

Description

technical field [0001] The invention relates to an automobile 1 / 4 suspension test bench, which belongs to the subject field of vehicle engineering. Background technique [0002] Automobile suspension is a component that connects the wheel and the vehicle body, and plays the role of bearing the weight of the vehicle body and isolating road vibrations. Its performance affects the passability, comfort and handling stability of the vehicle. Suspension test bench is an indispensable experimental equipment for the design, production and manufacture of automobile suspension system. The automobile suspension test bench represented by "four uprights" sold on the market is expensive, and it is difficult for general enterprises and institutions to bear. Therefore, the market needs a low-cost test bench that can meet the requirements of suspension experiments. The present invention meets this requirement. Contents of the invention [0003] The car 1 / 4 suspension test bench, (such a...
