Drum device of indoor tyre testing machine

Abstract

The invention discloses a drum device of an indoor type testing machine. The drum device is characterized by comprising a smooth steel base drum, a plurality of modularized road simulation units and a plurality of dynamic balance compensation units, wherein a spindle mounting hole is arranged in the centre of the smooth steel base drum axially; the modularized road simulation units are respectively detachably arranged on outer surface of the circumferential surface of the smooth steel base drum, and the modularized road simulation units are arranged in an end-to-end connecting manner; and the dynamic balance compensation units are respectively detachably arranged on the inner surface of the circumferential surface of the smooth steel base drum, and the dynamic balance compensation units are in dynamic balance compensation matching with the modularized road simulating units. Therefore, the drum device integrates road spectrum and road simulation in a proving ground of the modularized road simulation units and dynamic balance compensation of the dynamic balance compensation units, thereby simulating a tyre test in the proving ground.

Description

technical field [0001] The present invention relates to a component of an indoor tire testing machine, more specifically, to a drum device of the indoor tire testing machine. Background technique [0002] For a long time, there has been a lack of effective and efficient testing methods for the impact of road obstacles on tire performance. This is a difficult problem that has plagued my country's automobile and tire industries. [0003] At present, the common practice is to lay test roads of different materials and road spectrums on large-scale proving grounds, such as cement roads, asphalt roads, pit roads, stone roads, pebble roads, washboard roads, Belgian roads, pothole roads, Wave Road etc. [0004] The road test of a large proving ground certainly has its advantages, but its disadvantages are also obvious: [0005] 1. The investment and maintenance costs are astonishingly high; [0006] 2. The test environment (such as temperature, humidity, cloudy, rainy, snowy, etc...

AI Technical Summary

Problems solved by technology

[0005] 1. The investment and maintenance costs are astonishingly high;

[0006] 2. The test environment (such as temperature, humidity, cloudy, rainy, snowy, etc.) is difficult to control;

[0007] 3. Different driving habits of drivers will bring about differences in test results;

[0008] 4. Tires and vehicles, especially vehicle suspensions, are difficult to separate for independent performance evaluation;

[0009] 5. The test period is long, and it is easily affected by thunderstorm weather;

[0010] 6. Some road surfaces (such as pitted roads and wavy roads) are dangerous to the driver and the tested vehicle

[0012] So far, indoor tire testing machines only have a smooth steel base drum, or apply friction paper on the side of the smooth steel base drum, or add strip-shaped protrusions on the side of the smooth steel base drum, However, none of these design schemes can simulate the road map and road surface in the proving ground, so the tire test in the proving ground cannot be simulated.
