A truck for a railway vehicle has a truck frame with four individual wheels, which are mounted so that they can rotate around horizontal axles, and whereby one wheel pair is driven. To be able to negotiate tight curves with minimal wear, maximum safety and low construction costs, and to be able to achieve higher speeds on straight segments of track, the driven wheel pair can be steered radially with respect to the curve around a common vertical axis as a function of a setpoint determined by a sensor system, while the non-driven individual wheels are combined into a self-steering individual wheel module so that they can each pivot around their own vertical axes, and can be coupled together so that they are synchronized by means of a steering device.

Secondary suspension for rail vehicles

A bogie for rail vehicles, in particular a driven bogie, with a bogie frame, includes two or more wheelset units each of which comprises at least one drive unit and/or brake unit. The wheeset units are connected with the bogie frame via a primary suspension. A secondary suspension connects a vehicle body with the bogie frame. A rigid connecting link extends from at least one of the wheelset units for connecting the bogie to the vehicle body. The rigid connecting link is coupled to the wheelset unit at its virtual center of rotation. Where practical, the center of rotation and the center of mass are coincident to minimize the moment of inertia of the wheelset units.

Bogies for rail vehicles

Rail vehicle with at least two car bodies wherein at or near their connecting point a truck is provided which carries both car bodies, wherein furthermore an intermediate link is arranged between the car bodies, and one car body is rotatably mounted at the intermediate link about a lateral axis, and the other car body is rotatably mounted at the intermediate link about a vertical axis.

In a bogie for rail vehicles, in particular a driven bogie, with a bogie frame, two or more wheelset units which may comprise at least one drive unit and/or brake unit, connected with the bogie frame via a primary suspension, and a secondary suspension for connecting a vehicle body with the bogie frame, a rigid connecting link extends from at least one of the wheelset units for connecting the bogie to the vehicle body. The rigid connecting link is coupled to the wheelset unit at its inertial pole or center of mass.

A bogie for rail vehicles, particularly commuter or short-haul vehicles, has two wheel sets spaced apart in the direction of travel. One wheel set is mounted upon a wheel mounting frame which is coupled to a tranverse member of the bogie frame by way of an intermediate beam member. The arrangement is such that a lateral force applied to one wheel of the set by a curved rail will be translated into a rotational force to rotate the wheel mounting frame and therewith the wheel set, to negate the aforesaid lateral force. Such an arrangement reduces wheel flange wear and the risk of derailment.

A wheel set guidance for trucks of rail vehicles, especially commuter traffic vehicles. To have a continuously extending floor on as low a level as possible, a truck with free wheels is proposed where the free wheels are mounted in pedestal bearings that are connected with a frame structure that is connected to the truck frame in such a way as to be pivotable in a vertical direction. One of the wheel sets can be driven, with the free wheels thereof being connected in a twist-resistant manner via gear arrangement, so that from a motion standpoint the same effect is achieved as if the driven wheel set were connected with a rigid wheel set shaft, but without this shaft being in the way of the floor, so that a vehicle equipped with this truck can have a continuously extending floor on a low level.
