A sandwich two-way shock-absorbing wheel

Abstract

The invention discloses a sandwich two-way shock-absorbing wheel, which adopts a PP+TPR+PP structure, and PP and TPR are on the same wheel arc surface to ensure the shock-absorbing effect and mute effect while strengthening the support to meet the demand of heavy load. The invention provides a sandwich two-way damping wheel, comprising: a wheel core (1), a wheel inner bag (2) and a wheel outer bag (3); the wheel core (1) includes a support part (11) and a reinforcement part (12); The supporting part (11) is an annular column structure; the inner wheel bag (2) is matched and embedded in the supporting part (11), the outer wheel bag (3) is located between the supporting part (11) and the reinforcing part (12), and the reinforcing part ( 12) Match and embed the outer side of the wheel outer bag (3); the wheel core (1) is made of TRP material; the wheel inner bag (2) and the wheel outer bag (3) are made of PP material.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a sandwich two-way damping wheel. Background technique [0002] Tires are widely used in various car bodies, which are convenient for transportation and travel. [0003] The sandwich wheel is a wheel in which two materials are alternately and superimposed. [0004] At present, the common sandwich wheels are: nylon + rubber + nylon structure and PP + TPR + PP structure, among them, the sandwich wheel of nylon + rubber + nylon structure has a heavy load and high cost; the sandwich wheel of PP + TPR + PP structure has a heavy load Light and low cost. [0005] The tire is composed of the wheel core and the wheel outsourcing. Generally, the side of the tire is straight. When carrying heavy goods, the steering resistance is large, and the side is prone to protruding rubber, which leads to a short service life of the wheel. Contents of the invention [0006] The invention provides a sandwich...
