Embodiment Construction
[0030] The core of the invention is that the wheel and the guide rail are in pure rolling contact, thereby reducing the running noise of the vehicle and reducing the wear of the wheel and the guide rail.
[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] see figure 2 , shows the pure rolling contact structure (hereinafter referred to as the wheel-rail contact structure) of the low-noise, less-wearing rail transit wheel and guide rail of the present invention. The contact guide between them is changed from sliding contact to pure rolling contact, thereby reducing noise and reducing wear. In fact, the left and right wheels and the guide rail are symmetrical structures, without loss of generality, the following will further describe the wheel and guide rail on one...
