Abstract

A traveling bogie includes a steerable wheel, a bogie main body configured to support the steerable wheel, a guide apparatus pivotally supported by the bogie main body and turned by receiving a reaction force from a guide rail, a steering mechanism configured to apply a steering force to the steerable wheel using the reaction force received by the guide apparatus, and an assist mechanism configured to apply an auxiliary steering force for assisting with the steering force from the steering mechanism to the steerable wheel.

First claim

The invention claimed is:

1. A traveling bogie that is guided by a guide rail installed along a track to travel, the traveling bogie comprising:
a steerable wheel;
a bogie main body configured to support the steerable wheel;
a guide apparatus that is pivotally supported by the bogie main body and turned by receiving a reaction force from the guide rail;
a steering mechanism configured to apply a steering force to the steerable wheel using the reaction force received by the guide apparatus; and
an assist mechanism configured to apply an auxiliary steering force for assisting with the steering force from the steering mechanism to the steerable wheel,
wherein the assist mechanism comprises:
an actuator configured to generate the auxiliary steering force;
a detection unit configured to detect a turning angle of the guide apparatus; and
a control unit configured to control an operation of the actuator based on the turning angle of the guide apparatus detected by the detection unit.

2. The traveling bogie according to claim 1 , wherein the actuator is attached to the bogie main body.

3. The traveling bogie according to claim 2 , wherein a pair of steerable wheels are provided separated by an interval in a vehicle width direction, and
a pair of actuators are individually provided with respect to the pair of steerable wheels.

4. A track-type vehicle comprising:
the traveling bogie according to claim 3 ; and
a vehicle body supported by the traveling bogie.

5. A track-type vehicle comprising:
the traveling bogie according to claim 2 ; and
a vehicle body supported by the traveling bogie.

6. The traveling bogie according to claim 1 , wherein a pair of steerable wheels are provided separated by an interval in a vehicle width direction, and
a pair of actuators are individually provided with respect to the pair of steerable wheels.

7. A track-type vehicle comprising:
the traveling bogie according to claim 6 ; and
a vehicle body supported by the traveling bogie.

8. A track-type vehicle comprising:
the traveling bogie according to claim 1 ; and
a vehicle body supported by the traveling bogie.
