Problems solved by technology

That is, when the actuator 64 carries out the same control under the situation of any turn left and right, the steering angle of the road wheel 57 positioned at the inside of the curve portion and the steering angle of the road wheel 57 positioned at the outside become different when turning right and turning left. The same, as a result, the tires of the road wheels 57, etc., may be partially worn

Abstract

A bogie (2) for a track-guided vehicle (1) traveling on a predetermined track (3). The bogie (2) is provided with an axle (5) to which steerable travel wheels (6) are mounted, a guide frame (10) provided below the axle (5), a first pair of guide wheels (14) rotatably mounted to a vehicle end section-side end portion (10a) of the guide frame (10), a second pair of guide wheels (16) rotatably mounted to a vehicle center-side portion (10b) of the guide frame (10), a pair of tie rod arms (18) mounted to the axle (5) and formed so as to extend from the axle (5) toward the vehicle center side, and a pair of tie rods (19), each tie rod (19) interconnecting the guide frame (10) and each of the pair of tie rod arms (18).

Description

technical field [0001] The present invention relates to a track-based vehicle that runs on a predetermined track, and specifically relates to a track-based vehicle bogie that is guided and manipulated by guide rails provided on the track. Background technique [0002] Conventionally (for example, Patent Document 1 and Patent Document 2), there have been proposed bogies for track-based vehicles that run along guide rails provided on a track by providing a steering mechanism using guide wheels. [0003] Figure 10 An example of a conventional rail-based vehicle bogie is shown, and a plan view of a front-side bogie in the vehicle front-rear direction of the rail-based vehicle is shown. [0004] Such as Figure 10 As shown, a bogie 52 of a rail-based vehicle 51 travels along guide rails 53 provided on a rail, and is provided with a guide frame 54 formed in a rectangular shape in plan view. A pair of guide wheels 55 are rotatably attached to the vehicle end side portion 54a of t...
