Problems solved by technology

In production, it was found that some rail wheels have excellent mechanical properties, but forging is more difficult, and the pass rate of forging is low, resulting in higher costs and delayed delivery
However, the rail wheels in the prior art cannot meet the requirements of light weight, and the manufacturing process is complicated, which cannot meet the needs of mass production.

Abstract

The invention provides a bent spoke rail wheel applied to the technical field of railway vehicle parts. Each wheel spoke (2) of the bent spoke rail wheel is arranged of a curved surface structure, oneend of each spoke (2) is connected with a hub (1), the other end of each spoke (2) is connected with a rim (3), each wheel spoke (2) comprises a spoke side face I (4) and a spoke side face II (5), multiple side face I curved surfaces (6) are arranged on each spoke side face I (4) from the end connected with the hub (1) to the end connected with the rim (3), and multiple side face II curved surfaces (7) are arranged on each spoke side face II (5) from the end connected with the hub (1) to the end connected with the rim (3). By the adoption of the bent spoke rail wheel, the good braking performance and easy volume production are guaranteed, meanwhile, the wheel is small in weight, the reasonable strength, rigidity and braking thermodynamic performance of the wheel are guaranteed, and competitiveness is improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle components, and more specifically relates to a curved web rail wheel. Background technique [0002] The weight of the rail vehicle body directly affects energy consumption. The optimal design of the vehicle components and the use of new materials can effectively reduce the weight, thereby reducing energy consumption. The rail wheel is mainly composed of three parts: the hub, the spoke plate and the rim. The wheel structure mainly refers to the spoke plate structure. The radial plate structure is mainly divided into five types: S-shaped spoke plate, bell-shaped spoke plate (also known as double S-shaped spoke plate), basin-shaped spoke plate, straight spoke plate, and oblique spoke plate. S-shaped spokes, bell-shaped spokes (also known as double S-shaped spokes), and pot-shaped spokes can be classified as curved spokes. To design a tread-braked rail wheel, both stress and deformation must be...
