AI Technical Summary

Technical Problem

The heat dissipation effect of existing locomotive spoke wheel hubs is poor, resulting in the attenuation of the friction coefficient of the brake shoe in the brake, poor braking effect and failure, increasing the risk of safety accidents.

Method used

A locomotive spoke hub heat dissipation structure is designed. By distributing multiple spoke mounts and heat sinks on the hub body, a cluster of heat sinks that intersect horizontally and longitudinally is formed, increasing the heat dissipation surface area and improving the overall torsion resistance of the hub.

Benefits of technology

It effectively meets the high-temperature heat dissipation problems of spoke wheel hubs and brake systems during continuous long downhill braking, solves the safety problems of poor braking effect and failure, reduces the weight of the vehicle, and improves the safety factor.

Abstract

The utility model discloses a locomotive spoke hub heat dissipation structure which is characterized in that the locomotive spoke hub heat dissipation structure comprises a hub body, a plurality of left spoke installation seats are evenly distributed on the periphery of the left side end of the hub body, a plurality of right spoke installation seats are evenly distributed on the periphery of the right side end of the hub body, and spoke installation holes are formed in the left spoke installation seats and the right spoke installation seats. Cooling fins are arranged on the periphery of the middle of the hub body and comprise cooling ridges extending in the circumferential direction of the hub body and transverse cooling fins extending in the radial direction of the hub body. The spoke hub has the advantages that the braking heat dissipation surface area is increased, the strength of the spoke hub is improved, and the weight is reduced. The problem of continuous high-temperature heat dissipation of the spoke hub and a braking system during continuous long downhill braking is effectively solved, torsional fatigue and radial load fatigue are reduced through connection of the straight pulling spokes and the hub heat dissipation structure, the service life of the spokes for durability and looseness prevention is prolonged, the weight of the whole vehicle is reduced, and the safety coefficient is improved.
