Sandwich bidirectional damping wheel

Abstract

The invention discloses a sandwich bidirectional damping wheel. The sandwich bidirectional damping wheel comprises a wheel core (1), an inner wheel wrapping part (2) and an outer wheel wrapping part (3), wherein the wheel core (1) comprises a support part (11) and a reinforcing part (12), and the support part (11) is of an annular cylinder structure; the inner wheel wrapping part (2) is embedded into the support part (11) in a matched manner, the outer wheel wrapping part (3) is located between the support part (11) and the reinforcing part (12), and the reinforcing part (12) is embedded intothe outer side of the outer wheel wrapping part (3) in a matched manner; the wheel core (1) is made of TRP, and the inner wheel wrapping part (2) and the outer wheel wrapping part (3) are made of PP.The sandwich bidirectional damping wheel has the advantages that the PP+TRP+PP structure is used, the PP and the TPR are located on the same wheel cambered surface, a damping effect and a silencing effect are guaranteed, support is enhanced, and heavy load requirements are satisfied.

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...
