Problems solved by technology

However, the impact force provided by the traditional impact test has the problem of a single direction, and the road conditions when the car is actually driving are usually more complicated, resulting in inaccurate test results for the wheel cover, so the tires are prone to damage when the car is running

Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1-5 As shown, the embodiment of the present invention provides an impact test device for a wheel cover. The impact test device is placed on the test platform as a whole, and it includes a bracket, a swing arm mechanism with a tire mounting part, and a flexible traction device connected to the swing arm mechanism. Pull piece 11. The bracket is placed on the test platform, which has at least two installation holes, and the distance between each installation hole and the test platform is not equal to each other. The distance refers to the vertical distance between the center of the installation hole and the upper surface of the test platform. direction distance. The side of the swing arm mechanism opposite to the tire mounti...

Abstract

The invention discloses an impact test device for a wheel casing. The impact test device comprises a support, a swing arm mechanism with a tyre installation portion and a flexible drawing member connected with the swing arm mechanism, the support is arranged on a test platform and includes at least two installation holes, the distances from different installation holes to the test platform are different from one another, the side, opposite to the tyre installation portion, of the swing arm mechanism is mounted in one installation hole detachably, a middle segment of the flexible drawing member is connected to the support, the swing arm mechanism includes a swinging stroke relative to the support under the effect of the flexible drawing member, and the stroke further comprises an impact swing stroke gradually close to and contact with the test platform and an elevated swing stroke gradually far from the test platform. The impact test device can simulate the condition of an automobile during driving more effectively, and enables an impact test result of the wheel casing to be more accurate.

Description

technical field [0001] The invention relates to the technical field of reliability verification of wheel covers, in particular to an impact test device for wheel covers. Background technique [0002] The wheel cover of the tire is directly connected to the rim, and the connection strength between the two directly determines the reliability of the wheel cover, and the method of verifying the reliability of the wheel cover is generally road verification, combined with some bench tests, mainly to verify the reliable assembly of the wheel cover Sex and its own impact resistance, aging resistance, etc. [0003] The impact test is the most important verification method and judgment standard. It mainly verifies whether the wheel cover is qualified through the impact force applied to the wheel cover. However, the impact force provided by the traditional impact test has the problem of a single direction, and the road conditions when the car is actually running are usually more compl...
