Abstract: The invention relates to a contact assembly for electrical HV connections, having a housing with touch protection which has a through-opening extending from a first housing end of the housing to a second housing end of the housing which is spaced apart from the first housing end along an axial direction, wherein the housing has at least one radially inwardly protruding touch protection element at the second housing end and, has in the through opening, at least one latching surface extending in a circumferential direction around the axial direction which has a surface normal directed towards the second housing end, having a contact element which can be inserted from the first housing end into the through-opening towards the second housing end in any desired angular position around the axial direction, wherein at least one latching protrusion of the contact element latches with the at least one latching surface in each of the desired angular positions when the contact element is inserted into the through-openin

Abstract: A device for machining wheel running surfaces of a wheel for a rail vehicle includes a wheel machining machine having a machining tool for performing a re-profiling process on the wheel and a rolling tool for performing a rolling process on the wheel and applying a rolling force to the wheel. A clamping unit is alternatively used as a receptacle for the machining tool or for the rolling tool. A first drive motor drives a first feed axle to translate the clamping unit along a first axis. A second drive motor drives a second feed axle to translate the clamping unit along a second axis perpendicular to the first axis. A control module adjusts the rolling force by controlling torques of the first and second drive motors.

Abstract: A connector includes a housing defining a first receiving space and a second receiving space, a conductive electrical connecting element arranged in the second receiving space, a retaining element engaging around at least portions of the electrical connecting element and a contact-securing insert arranged in the first receiving space. The conductive electrical connecting element includes a contact sleeve adapted to connect to a contact pin, and an electrical contact adapted to connect to an electrical conductor. The contact-securing insert fixing the electrical connecting element and the retaining element within the housing in an axial direction of the electrical connecting element.

Abstract: A method for machining the wheel running surfaces of wheels for rail vehicles using a wheel machining machine is described herein. The method includes performing a rolling process on the wheels with a rolling tool that applies a rolling force to the wheels, and adjusting the rolling force by controlling the torques of drive motors of feed axles of the rolling tool.

Abstract: The invention concerns a rolling unit for machining the wheel running surfaces of wheelsets for rail vehicles, with the rolling unit featuring at least one work roller by means of which the wheel running surface to be machined is subjected to a deep rolling process following manufacture of the wheelset in new condition or, at a later date, after reprofiling to increase the service life of the wheel running surfaces. The task is solved to create a relevant rolling unit by means of which the wheel running surfaces can be deep-rolled in the forward feed process using work rollers. This task is solved by the rolling unit featuring a base body on which a support arm is located in a vertical position to the base area, on which a receptacle is supported that is unilaterally fixed in position via a thread in the support arm and on which an angular contact ball bearing is located; this supports at least one work roller featuring at least two different rolling radii.
