Problems solved by technology

When such a self-guided rail vehicle travels straight, the guide wheels will turn due to the unevenness of the guide surface, which in turn will cause the rail vehicle to turn, thereby affecting the running stability and ride comfort of the rail vehicle.

Embodiment Construction

[0047] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] Such as Figure 1 to Figure 14 As shown, the embodiment of the present invention provides a bogie for a rail vehicle, including a traveling wheel 10, a guide frame 40, a multi-link mechanism 30, a slewing bearing 80 and a first elastic member 100, a multi-link mechanism and a traveling wheel 10 connections. The slewing support 80 includes a fixed part and a rotating part, the fixed part is connected with the vehicle body, the steering part can rotate relative to the fixed part, the rotating part includes a driving part 8022 and a driven part 8023, the driving part 8022 is connected with t...

Abstract

The invention belongs to the technical field of railway vehicles, and particularly relates to a bogie and a railway vehicle, the bogie and a driven part have a first working state and a second working state, when the railway vehicle runs along a straight line, if a guide surface is uneven, steering of a guide wheel is transmitted to a guide frame, and a driving part connected with the guide frame rotates; however, as the first elastic piece is arranged between the driving piece and the driven piece, the driving piece can compress the first elastic piece, and at the moment, the driven piece is still kept still, so that the multi-connecting-rod mechanism connected with the driven piece cannot rotate, the walking wheels connected with the multi-connecting-rod mechanism cannot steer, and therefore steering of the railway vehicle is avoided; and the running stability and the riding comfort of the railway vehicle are improved. When the railway vehicle steers, the driving part rotates firstly, when the first elastic part is in the maximum deformation state, the driven part is in the second working state, the driven part and the driving part rotate together, and then the multi-connecting-rod mechanism is driven to rotate, and the walking wheels are driven to steer.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a bogie and a rail vehicle. Background technique [0002] In the existing self-guided rail vehicles, when turning, the guide wheels will drive the guide frame to rotate, and the guide frame is connected with the running wheels, thereby driving the steering of the running wheels and the rail vehicle. When such a self-guided rail vehicle travels straight, the unevenness of the guide surface will cause the guide wheels to turn, which in turn will cause the rail vehicle to turn, thereby affecting the running stability and ride comfort of the rail vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is: when the existing self-guided rail vehicle travels straight, the rail vehicle will turn due to the unevenness of the guide surface, thereby affecting the running stability and riding comfort of the rail vehicle. ...
