Embodiment

[0036] Example: such as figure 1 , image 3 , Figure 4 and Figure 7 As shown, a tire impact resistance detection drum includes a drum body 2 that is pressed against a tire 1 and a first mounting portion 3 that can be installed with a first wedge 4 that simulates an obstacle, wherein the drum body 2 is parallel to the axis of the tire 1, the first installation part 3 is arranged on the side of the drum body 2 and corresponds to the area of ​​the shoulder of the tire 1; the first installation part 3 includes a rotating part 5 pivotally connected with the first wedge , and the limit part 6 that can adjust and limit the rotational position of the first wedge 4 . When the tire shoulder impact resistance is tested, for the setting of the first installation part 3, the length and installation angle of the first wedge 4 can be selected according to the needs, that is, the first wedge 4 can simulate the tire rolling over different raised obstacles on the road surface , so as to c...

Abstract

The invention provides a tyre impact-resistant detection drum, which comprises a drum body crimped onto a tyre and rolling oppositely relative to the tyre, and a first installation part of the drum body, wherein a simulated obstacle can be installed on the first installation part. The axis of the drum body is parallel to the axis of the tyre. The first installation part is arranged on the side surface of the drum body and is positioned corresponding to the tyre shoulder of the above tyre. The first installation part is composed of a rotation part pivoted to the drum body, and a limiting part capable of being adjusted to limit the rotation position of the drum body. By means of the tyre impact-resistant detection drum, the flexing resistance of the sidewall of the tyre can be accurately detected.

Description

technical field [0001] The invention belongs to the field of test and detection devices, in particular to a tire impact resistance detection drum. Background technique [0002] With the improvement of people's requirements for vehicle driving safety performance, the impact of tire impact resistance on vehicle driving safety has been highly concerned. The tire crown is the main part of the tire running in contact with the ground, so it should have good impact resistance. The sidewall of the tire plays the role of protecting the carcass cord from damage, so it should have good flex resistance. Therefore, testing the impact resistance of the tire crown and the flex resistance of the sidewall after the shoulder is impacted is useful for predicting early damage during use (such as "pattern drop", "shoulder void" and cord delamination, etc.) ), improving the ride comfort of the tire and prolonging the overall service performance of the tire have high practical value.
