Title:
SANDWICH BIDIRECTIONAL VIBRATION-DAMPING WHEEL
Document Type and Number:
WIPO Patent Application WO/2019/114283
Kind Code:
A1
Abstract:
Provided is a sandwich bidirectional vibration-damping wheel, comprising a wheel core (1), an inner wheel wrapping part (2) and an outer wheel wrapping part (3), wherein the wheel core (1) comprises a supporting part (11) and a reinforcing part (12); the supporting part (11) is of an annular cylinder structure; the inner wheel wrapping part (2) is embedded into the supporting part (11) in a matched manner, the outer wheel wrapping part (3) is located between the supporting part (11) and the reinforcing part (12), and the reinforcing part (12) is embedded into the outer side of the outer wheel wrapping part (3) in a matched manner; the wheel core (1) is made of a TPR material; and the inner wheel wrapping part (2) and the outer wheel wrapping part (3) are made of a PP material. The vibration-damping wheel is of a PP+TPR+PP structure, and the PP and the TPR are located on the same wheel cambered surface, so that a vibration-damping effect and a silencing effect are guaranteed, and at the same time, support is enhanced and heavy load requirements are satisfied.
