The invention relates to a method for contactlessly and dynamically detecting the profile of a solid body. At least one light beam is generated by a laser device and expanded to form a linear light band projected onto the moving surface of the solid body. Light reflected from the surface of the solid body is focused in an imaging device whose optical axis is at a fixed triangulation angle to the direction of projection of the laser device and which is arranged at a fixed based distance from the laser device. The reflected light is detected by a planar light receiving element at a frequency that is high by comparison with a speed of movement (v) of the solid body after which the measured values of the profile are obtained as a function of the triangulation angle and the base distance.

Method for contactlessly and dynamically detecting the profile of a solid body

An idler wheel axle for single-axle or double-axle chassis of rail vehicles having individually mounted wheels and U-shaped, dropped-framed vehicles with lateral carrying legs, wherein each wheel is rotatably mounted on the inside of the associated carrying leg, and on an axle stub of the carrying leg via a wheel mounting, and wherein each wheel is torsionally connected on an inside thereof to a shaft that extends outward through orifices within the wheel and the carrying leg.

Idler wheel axle for rail vehicles

A vehicle wheel includes a wheel hub rotatably mounted on a stationary axle and a running tread, tire or the like connected with the wheel hub. A device for connecting structural components such as, for instance, a transmission part or a brake disk, for the purpose of transmitting a torque between the wheel hub and the structural component to be connected is provided on the external end face of the wheel hub. In order to provide a modularly designed vehicle wheel easy to mount and dismount, the device for connecting structural components is applicable facultatively and a fastening device spacially separated from the device for facultatively connecting structural components is provided on the external end face of the wheel hub. The vehicle wheel may be designed as a driven wheel or a loose wheel with or without brake. By separating torque transmission and power transmission, mounting and dismounting of the vehicle wheel is substantially facilitated.

Vehicle wheel, in particular for a low-platform vehicle

The present invention pertains to a driven loose wheel axle with individually mounted wheels for single-axle or double-axle chassis for rail-borne vehicles, especially for chassis or bogies on low-platform vehicles, wherein a drive is fastened to the chassis frame on the outside on each longitudinal side of the chassis and the drive is connected to the corresponding loose wheel via a cardanic double coupling. According to the present invention, a wheel-carrying frame (1) with contact surfaces (14) for the primary spring system surrounds the two wheels (2) from the outside; the driven interface (3) of the cardanic double coupling is arranged on the inner side of the wheel and the drive interface of the cardanic double coupling is arranged outside the wheel-carrying frame. The cardan shaft (5) provides a connection between the drive interface and the driven interface (3) and is led through a central opening of the wheel (2) and of the wheel-carrying frame (1).

Driven loose wheel axle

A brake for rail cars comprises a floating caliper disc brake attached to a cylindrical housing element of a drive housing. The drive housing may be the motor housing, the transmission housing or a common housing for the drive motor and the transmission. The cylindrical housing element has an opening in its peripheral wall in which the floating caliper is mounted. The actuator is mounted in an entry in the peripheral wall of the drive housing. This mounting arrangement allows easier accessiblity to the brake during servicing operations and provides for ventilation of the brake disc.
