Abstract: A motor vehicle drive shaft has a receptacle tube component with a receptacle internal diameter and a push-fit component with a push-fit external diameter. The push-fit external diameter is smaller than or equal to the receptacle internal diameter. The receptacle tube component and the push-fit component can be rotated about a common drive shaft rotational axis and extend along the latter in a longitudinal direction. The receptacle tube component and the push-fit component are connected to one another for the transmission of torque. A connecting component is provided, wherein the connecting component is connected in a torque-conducting manner to the receptacle tube component by way of a receptacle connection. The connecting component is connected to the push-fit component by way of a push-fit connection. At least one of the two connections is configured as a combined frictionally locking and positively locking shaft/hub connection.

Abstract: A method for producing a shaft-hub connection in which a shaft component and a hub component are placed into a joined state in the form of a frictional shaft-hub connection. The shaft component has a toothed region having teeth with a height H, and the hub component has a mating toothed region having a mating region internal diameter d. The hub component is pushed onto the shaft component in a longitudinal direction to produce the frictional shaft-hub connection and in the process geometrically reproduces the toothed region in the mating toothed region. The mating toothed region passes over a cylindrical centering region with an outer diameter D before coming into contact with the toothed region. The outer diameter D is at most 0.2 mm and at least 0.005 mm smaller than the mating region inner diameter d. The centering region has a length L greater than 1 mm.

Abstract: The subject matter of the present invention relates to a metal foil with an embossed structure for use in the purification of exhaust gas as well as to a tool and a method for its production. In the direction of the main flow, the metal foil has alternating peaks with ascending flanks and descending flanks and valleys, with the peaks and valleys being divided into rows parallel to the direction of the main flow and with the peaks and valleys of adjacent rows being staggered in the direction of the main flow in such a way that the ascending flanks and the descending flanks of the staggered peaks form a trough which connects the staggered valleys.

Abstract: The invention relates to a holding device for a fixing an electronic component in a wheel. The holding device comprises at least one device carrier (5) for receiving and holding electronic components (6) and also comprises at least one at least partially elastic damper foot (7) which is permanently flexibly connected to the tire covering (1). The damper foot (7) has a dampening effect and is configured in such a way that it is elastic and tapered along the longitudinal axis thereof. The damper foot (7) can be fixed to the device carrier (5) and the tire covering (1) by adhesion or vulcanization, for example. In other embodiments, the damper foot (7) is also produced with the device carrier and the tire covering in a single piece made of tire material. Preferably, the damper foot can conduct heat and energy and contains a capacitive or inductive coupling for connecting two electronic components (6) or an antenna.

The troughs located in the region of the ascending flanks and descending flanks form irregular zones of disturbance and warps which render the exhaust gas turbulent and make it come into contact with the surface.
