Embodiment Construction

[0021] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

[0022] In the tire uniformity testing machine, the test tire is driven to rotate by the load wheel. In the high-speed test state, the test tire and the testing equipment itself produce a certain vibration, and the resonance interference between the test tire and the load wheel cannot be ignored. This application proposes A tire high-speed test resonance interference processing device, which is mainly used on the load wheel. Through the transformation of the load wheel, the resonance interference between the load wheel and the test tire is reduced, thereby solving the problem of resonance interference in the existing high-speed tire uniformity test. Obvious technical issues.

[0023] Such as figure 1 and figure 2 As shown, bar-shaped grooves 2 are processed on the surface of the load wheel 1, and several bosses 3 are...

Abstract

The invention discloses a tire high speed test resonance interference processing device. A strip-shaped groove is machined in the surface of a load wheel; a plurality of bosses are arranged in the strip-shaped groove at intervals; the tops of the bosses are lower than the surface of the load wheel; the bosses do not contact with the side wall of the groove, so that a plurality of airflow passagesare formed between the bosses and the inner wall of the strip-shaped groove as well as between the bosses and the top of the groove; when the load wheel and a detection tire rotate, the detection tirecontacts the load wheel, air in front of the detection tire is squeezed into the strip-shaped groove, the strip-shaped groove is squeezed and deformed, and as a result, the air is squeezed to flow inthe airflow passages; the flow direction of the airflow is disturbed, so that the resonance frequency of the load wheel and the detection tire is broken, and therefore, the strip-shaped groove formsa silencing chamber, and detection resonance interference can be reduced, and the technical problem of obvious interference or resonance in an existing tire high-speed uniformity test can be solved.

Description

technical field [0001] The invention belongs to the technical field of tire detection, and in particular relates to a high-speed tire test resonance interference processing device. Background technique [0002] Tires are the main action-executing components of motor vehicles. The stability of tire performance and compliance with safety standards will directly determine the safety of personnel using motor vehicles. A tire is a circular rotatable body with a tubular cross section, which is formed by laminating, forming and shaping multiple layers of rubber prefabricated materials with steel cords and composite rubber prefabricated materials. The tires with the above-mentioned structure inevitably have problems such as uneven density and deformation in the constituent materials, which are often referred to as uneven tires. [0003] Tires with a certain degree of unevenness will cause car vibration or noise during rotation, which will affect the speed, comfort or stability of t...
