Internal and external double-vibration-reduction type bogie wheel for tracked vehicle

Abstract

The invention provides an internal and external double-vibration-reduction type bogie wheel for a tracked vehicle. The internal and external double-vibration-reduction type bogie wheel comprises a wheel disc, a protection plate, an external vibration reduction rubber ring, an internal vibration reduction rubber ring and a hub. The external vibration reduction rubber ring is fixed to the rim of thewheel disc, the internal vibration reduction rubber ring is fixed to the outer end face of the wheel disc and the inner end face of the protection plate, and after the internal vibration reduction rubber ring and the external vibration reduction rubber ring are fixed to the wheel disc, the protection plate and the hub are connected in a fastened mode through bolts. The internal and external double-vibration-reduction type bogie wheel can solve the problems that a single internal vibration reduction type bogie wheel is poor in vibration reduction effect and difficult to dissipate heat, and theservice life of the bogie wheel is short due to the fact that an external vibration reduction piece of a single external vibration reduction type bogie wheel is prone to abrasion and failure. The bogie wheel is excellent in vibration reduction performance, long in service life, high in reliability and capable of meeting the requirements for high-speed and stable running of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of tracked vehicle road wheels, and in particular relates to a tracked vehicle with inner and outer double damping type road wheels. Background technique [0002] Tracked vehicle road wheels are wheels used by tracked vehicles to support the car body and keep the car body rolling on the track ground section. At present, the road wheels are divided into various forms without vibration damping parts (all metal), internal vibration damping and external vibration damping. A road wheel with an all-metal rigid rim has the least rolling resistance, but it has the characteristics of transmitting dynamic loads to bearings, track shoes and track pins, especially when the vehicle is running at high speed, it has a great influence on the stability of the vehicle . The advantage of the road wheel with internal vibration reduction is that the dynamic load can be reduced by 33% to 50%. Load and noise reductions are smal...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes an inner and outer double damping road wheel for crawler vehicles to solve the technical problems of low service life of a single outer damping road wheel and poor vibration damping effect of a single inner damping road wheel and difficulty in heat dissipation, so as to further improve The damping effect of the road wheel improves the service life of the road wheel and the stability of the vehicle
