Embodiment Construction

[0012] Embodiments of the present invention provide a train wheel, such as figure 1 As shown (the left side of the wheel shown in the figure is the outer side when the wheel is actually used, and the right side is the inner side when the wheel is actually used), the train wheel includes a hub 1 and a rim 2, and the hub 1 and the rim 2 are connected by a web 3 ; Among them, the spoke plate 3 gradually thickens from the junction with the rim 2 to the junction with the hub 1 .

[0013] In this embodiment, the wheel is rolled as a whole, and then machined to meet the specified size and tolerance requirements. First, it is necessary to determine the rolling circle diameter of the wheel and the width of the wheel hub and rim. The rolling circle diameter of the wheel is a technology in the art. The nominal diameter of the wheel known to personnel, the width of the hub is the distance between the inner side and the outer side of the hub, the width of the rim is the distance between th...

Abstract

The invention provides a train wheel and a train. The train wheel comprises a hub and a rim, wherein the hub is connected with the rim through wheel disks, the thickness of the rim is 6%-7% of the diameter of a rolling circle of the wheel, and the thickness of the hub is 5%-6% of the diameter of the rolling circle of the wheel; the thickness of each wheel disk close to the rim is 2%-3% of the diameter of the rolling circle of the wheel; the thickness of each wheel disk close to the hub is 4%-5% of the diameter of the rolling circle of the wheel. According to the train wheel and the train, sizes of various parts of the wheel are optimized, stress distribution of the various parts can be even under the circumstance that the wheel is subjected to alternating stress, and the probability of the phenomena of cracking and damage to the wheel due to deformation and uneven stress is reduced.

Description

technical field [0001] The invention relates to wheel design technology, in particular to a train wheel and a train. Background technique [0002] At present, my country's rail trains are developing towards high-speed and heavy-duty directions. With the increase of train speed and axle load, wheels, as important bearing parts of rail trains, affect the safety and stability of trains. Therefore, their production requirements are becoming more and more stringent. [0003] However, in the prior art, since the wheels are affected by alternating loads during running and the stress distribution on the wheels is uneven, deformation and cracks of the wheels occur from time to time, seriously affecting the safety of the train. Contents of the invention [0004] The invention provides a train wheel and a train, which are used to solve the problems in the prior art that the wheels have uneven stress distribution and the wheels are prone to deformation and cracks. [0005] The presen...
