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.
Abstract:
A steering bogie provided with a pair of tires (13) positioned on both sides in the vehicle-widthwise direction, a primary suspension mechanism (51) for supporting the pair of tires (13) independent from a subframe (11), and a steering guide device (14) which is guided along guide rails (6) extending along a track (5), wherein the steering guide device (14) is equipped with: a guide frame (31); guide wheels (33) which roll as a result of contact with the guide rails (6), and are rotatably supported by the guide frame (31); and a guide frame support mechanism (32) for supporting the guide frame (31) by hanging from the primary suspension mechanism (51).
Abstract:
A snow removal device includes: a snow plow part that is mounted on a vehicle body traveling along a track in front of running wheels in which the vehicle body travels such that a lower end is separated from each of runways of the track with which the running wheels contact and that displaces forward snow of the running direction in a vehicle width direction as the vehicle body moves forward in the running direction; and a snow removal brush part mounted on the vehicle body in a rear of the snow plow part in the running direction and in front of the running wheels in the running direction so as to be disposed at a position at which a lower end thereof contacts the runway and at a position at which at least a portion thereof overlaps the snow plow part when viewed from the front.
Abstract:
A guide wheel (33) for guiding a vehicle along a track is equipped with an annular tread section (61) that comes into contact with a guide rail extending along the track and a pair of sidewall sections (62) that are formed continuing from both edges of the tread section (61) in the axial direction and extend inward in the radial direction, said guide wheel (33) being characterized in that protrusions (63a, 63b) are formed over the entire circumference of each of the sidewall sections (62).
Abstract:
This traveling bogie is provided with: steered wheels; a main body for supporting the steered wheels; a guide device turning when subjected to a reaction force from a guide rail; a steering mechanism for applying a steering force to the steered wheels utilizing the reaction force applied to the guide device; and an assist mechanism for applying an assist steering force to the steered wheels, the assist steering force assisting the steering force applied by the steering mechanism. The assist mechanism is provided with: a first operation arm pivoting together with the steered wheels in the direction in which the steered wheels are steered; a second operation arm rotating about a rotation axis relative to the main body in response to the turning of the guide device; and an elastically deformable section connected to the first operation arm and the second operation arm and elastically deformable.
Abstract:
A cooling device provided with cooling fins which: is provided in a wheel of a running wheel which integrally rotates with a axle shaft and has a brake device positioned in the interior thereof; and produces, by rotating in both the forward and reverse directions of the wheel, airflow which flows through the brake device via ventilation holes passing from the inside to the outside of the wheel. Therein, the cooling fins produce an airflow which flows through a plurality of decorative holes serving as the ventilation holes and formed in the wheel along the circumference centered around the rotational axis of the axle shaft.
Abstract:
This invention is equipped with: a steering shaft provided to an underframe of a carbody of a vehicle travelling on a traveling road surface of tracks; king pins provided as a pair to end sections of the steering shaft at both sides in the width direction; axle hubs swingably provided to the steering shaft via the king pins; tires mounted plurally to each of the axle hubs; guide wheels, which roll over guide rails provided to the tracks in the direction of extension of the tracks, and which are guided from the width direction of the tracks; a guide device part for supporting the guide wheels and the steering shaft; and a steering mechanism for causing the axle hubs to turn about the king pins in accordance with the displacement of the guide device part.
Abstract:
A vehicular suspension device has: a pair of primary support parts for respectively and elastically supporting elastic tires on a sub frame, the tires being located on both vehicle-widthwise sides; and a secondary support part for integrally and elastically supporting the pair of primary support parts and a car body via the sub frame, the secondary support part being located between the sub frame and the car body.
Abstract:
A snow removal device includes: a brush rotary shaft that is mounted on a vehicle body traveling along a track and in front of a running wheel of the vehicle body and that is rotated in a direction opposite to the rotation direction of the running wheel; a travel brush part that protrudes radially outward from an outer circumferential surface of the brush rotary shaft and comes into contact with a runway of the track with which the running wheel is in contact; and a brush pressing part that presses the travel brush part toward the runway. The travel brush part is provided in a spiral region formed on the outer circumferential surface of the brush rotary shaft in a spiral manner extending toward an axis direction in which the axis extends as going toward a circumferential direction of the brush rotary shaft.
Abstract:
A snow removal brush includes a brush rotary shaft that is disposed on each of opposite lateral surfaces of a vehicle body traveling along a track and in a vehicle width direction of the vehicle body and is supported by the vehicle body to be rotatable about an axis extending in a direction intersecting a track surface of the track, and a brush part that protrudes from an outer circumferential surface of the brush rotary shaft to a radial outer side. The brush part is formed to come into contact with trolley wires provided for the track and supplying electricity to the vehicle body.
