A vehicle is provided which is operable to motor power and/or pedal power, in particular an electric bicycle, which includes a crankshaft drive having a bottom bracket spindle, a chain ring, which outputs a drive torque for the vehicle to a chain, an electric drive, and a cone ring transmission for the continuous variation of a gear step ratio, the cone ring transmission and the electric drive being situated at the crankshaft drive, and the cone ring transmission being connected to the crankshaft drive and set up in such a way that a torque generated by the rider is transmitted to the chain ring.

Vehicle operable by motor and by muscular energy

The invention relates to a starter device () for cranking an internal combustion machine in a vehicle, having a pinion shaft () comprising a cranking pinion () at the front end and a pinion shaft () at the opposite end, slidingly guided and supported on a drive shaft () of the starter device () and received in a bearing by a bearing shell () of the starter device (), characterized in that the cranking pinion () has a solid lubricant coating () at least in the area of the circumferential toothing ().

Noise-optimized starter device

A valve for controlling a fluid, in particular for controlling a gas. The valve includes a valve housing which accommodates an electromagnetic actuating unit for a solenoid armature which is guided axially displaceably in the valve housing and which cooperates with a valve seat via a valve-closing member, so that a fluid stream from an inflow side to an outflow side of the valve is controllable. At least one lubricant chamber adjacent to the guide gap between the valve housing and the solenoid armature is provided.

Valve for controlling a fluid

A sintered plain bearing for motors and gear drives, having a running surface formed by a bearing bore and capable of having lubricant applied to it from lubricant reservoirs in the bearing, in which the bearing bore has, alternatingly distributed over the circumference, high-compaction small-pore running surfaces and axially extending low-compaction open-pore lubricant reservoirs. Lubrication is improved, especially in the initial phases of operation, by the fact that the lubricant reservoirs are constituted by channel structures having at least two longitudinal channels, and that at least in some of the channel structures, some of the channel crests remaining between adjacent longitudinal channels are in contact with the shaft received by the bearing bore in order to transfer lubricant.
