Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The purpose of the present invention is to provide a wheel tread damage testing device, to solve the problems of the above-mentioned prior art, so that the device can simulate the rolling contact wear and tear of the wheel tread when the train wheel pair bears the axle load and wind load at the same time under the state of high-speed rotation. Fatigue damage, followed by detection of tread damage.

[0031] In order to make the above objects, features an...

Abstract

The invention discloses a wheel tread damage testing device. The wheel tread damage testing device comprises a simulation mechanism, a driving mechanism and a braking mechanism; a wheel sample is abutted with a steel rail wheel; the rolling contact between a wheel set and an iron rail can be simulated; the wheel sample is mounted on a wheel axle in a sleeving mode and is in key connection with thewheel axle; a loading seat is arranged on the wheel axle; and a conical roller bearing and a thrust ball bearing are arranged between the loading seat and the wheel axle. A loading plate arranged onthe loading seat can be used for simultaneously loading a transverse wind load and axle weight for the wheel sample, so that the rolling contact abrasion and the fatigue damage of wheel treads when the train wheel set bears the axle weight and the wind load at the same time in a high-speed rotating state are simulated; and then the tread damage is detected, so that effective prevention measures can be made subsequently.

Description

technical field [0001] The invention relates to the technical field of train wheel set service performance testing, in particular to a wheel tread damage testing device. Background technique [0002] The wheel set is the part of the rolling stock that is in contact with the rail, and consists of two left and right wheels that are firmly pressed on the same axle. The role of the wheel set is to ensure the running and turning of the rolling stock on the rails, bear all the static and dynamic loads from the rolling stock, transmit it to the rail, and transfer the load caused by the uneven track to the parts of the rolling stock. In addition, the driving and braking of the rolling stock also work through the wheelset. [0003] The wheel set is an important part of the running part of the locomotive. Frequent braking and turning will cause side wear, scratches and peeling of the tread surface, which has a very important impact on the safe operation of the train and the service l...
