Abstract

The invention discloses an integral wheel for a locomotive, comprising a hub, a spoke plate and a rim. The spoke plate is a curved structure, one end of the spoke plate is connected with the wheel hub, the other end of the spoke plate is connected with the rim, and the end of the rim is far away from the spoke plate. With rim and tread. The wheel of the present invention can be applied to railway locomotives, is suitable for tread braking or axle disc braking, and is easy to mass produce. The spoke includes a hub-spoke transition area, a spoke main body and a rim-spoke transition area, the hub-spoke transition area is located between the hub and the spoke main body, and the rim-spoke transition area is located between the rim and the spoke main body . Both the hub-spoke transition area and the rim-spoke transition area are circular arc structures. The circular arc direction of the hub-spoke transition area is opposite to the circular arc direction of the rim-spoke transition area. The two ends of the web body are respectively tangent to the hub-web transition area and the rim-web transition area. The invention also discloses a design method for the integral wheel of the locomotive.

Description

technical field [0001] The invention belongs to the technical field of locomotive wheels, and particularly relates to an integral locomotive wheel and a design method thereof. Background technique [0002] The weight of the rail vehicle body directly affects the energy consumption. The optimal design of the structure and the use of new materials can effectively reduce the weight of the vehicle components, thereby reducing energy consumption. [0003] Rail wheels are mainly composed of hubs, spokes, and rims. The wheel structure mainly refers to the spoke structure. The web structure is mainly divided into 5 types: S-shaped webs (divided into forward S-shaped webs and reverse S-shaped webs), bell-shaped webs (also known as double S-shaped webs), basin-shaped webs, Straight spokes, inclined spokes. S-shaped webs, bell-shaped webs (also known as double S-shaped webs), and basin-shaped webs can be classified as curved webs. [0004] When designing tread brake rail wheels, bot...
