This railway vehicle is provided with: a bracket including a contact surface which is in contact with a second surface of a second plate member, and also including a recess which is provided in a portion facing an uneven surface; and a dynamic vibration absorber including a damper section which is located on the side opposite the contact surface and which is affixed to the bracket, and also including a weight section which is disposed on the side opposite the side to which the bracket is provided and which is disposed on the damper section. The bracket is separated from the uneven surface.

Railway vehicle

A bogie for a vehicle guided by guide wheels rotating while contacting a guide rail arranged along a guideway of the vehicle has a steering mechanism which operates in conjunction with the guide wheels to steer running wheels; a guide frame including a pair of traverse beams each of which is equipped with the guide wheels rotatably on both ends thereof and connecting members connecting the pair of the traverse beams with each other, the traverse beams being respectively arranged on a front side and a rear side of the bogie; a connection rod connecting the steering mechanism to the guide frame to move the steering mechanism in conjunction with the guide frame and steer the running wheels; and a turning bearing having a circular or an arc shape to rotatably support the guide frame on an axle of the bogie or a supporting member of the axle.

Bogie for guide rail type vehicle

A bogie for a vehicle which is guided by guide wheels that rotate while keeping contact with a guide rail arranged along a guideway of the vehicle. The bogie comprises a guide frame which includes a pair of transverse beams and a connecting member arranged between the pair of the transverse beams and each of the traverse beams being equipped with the guide wheels rotatably on both ends thereof, an axle supported on a non-turning part of the bogie such that the axle is capable of turning and running wheels which are attached to both ends of the axle. The running wheels are rigidly fixed to the axle and the guide frame is fixed to the axle so as to steer the guide frame, the axle and the running wheels integrally.

A vehicle includes a vehicle body, a bolster spring, a bogie supporting the vehicle body via the bolster spring and a vehicle height adjusting mechanism. The vehicle height adjustment mechanism includes an integrating device, a measuring device and an elastic force adjusting device. The integrating device integrates a first relative displacement amount at a first position between the vehicle body and the bogie and a second relative displacement amount at a second position between the vehicle body and the bogie. The measuring device measures an integrated value of the first relative displacement amount and the second relative displacement amount. The elastic force adjusting device adjusts elastic force of the bolster spring based on the integrated value so as to adjust a relative displacement amount between the vehicle body and the bogie.

Guideway type vehicle

An obstacle-removing device having brushes that can be retracted when the device is at the rear side in the traveling direction of the vehicle. The device includes a vertical frame positioned to the leading end in the traveling direction of the vehicle, and a lifting/lowering device attached to the vertical frame to lift and lower a brush holder having brushes and attached to a vertically movable member which can be lifted and lowered by the lifting/lowering device. The brush holder is pivotally attached to the vertically movable member such that the brush holder is tilting forward when the brushes held by the brush holder contact the running surface to perform an obstacle-removing operation.

Device attached to guided vehicle to remove obstacles on guideway

In a front gable portion ( ) of a rubber-tired new traffic vehicle ( ), an outer bumper ( ) is fixed to the exterior of an inner bumper ( ) constituting an underframe ( ), front beams ( ) and side beams ( ) are constructed between a roof frame ( ) and the outer bumper ( ), the front beams ( ) are inclined and curved in harmony with the streamlined design of the vehicle ( ), and straight portions ( ) of predetermined lengths are formed in lower end portions of the front beams ( ) along a vertical direction.
