A vehicle having an internal combustion engine mounted in the vehicle such that a crankshaft of the internal combustion engine runs in a longitudinal direction of the vehicle is provided with a flexible drive is provided that comprises a wheel, in particular a pulley, which is arranged such as to rotate about a longitudinal axis of the vehicle and which is arranged in front of the internal combustion engine when viewed in the direction of travel of the vehicle. The wheel has at least one weakened section which allows or facilitates a compression of the wheel in the longitudinal direction of the vehicle upon a head-on collision. In addition, the wheel may be arranged to cooperate with a recess in the front of the engine to permit further displacement of the wheel toward the engine during a collision.

A variable pitch pulley includes a rotary shaft, a fixed sheave fixed to the rotary shaft, and a moving sheave forming a belt groove with the fixed sheave. The moving sheave includes an inner sheave and an outer sheave radially stacked on the inner sheave. The pitch pulley further includes a moving sheave-positing unit determining relative positions of the inner and outer sheaves. The inner and outer sheaves are simultaneously moved in an axial direction of the rotary shaft in a first moving mode, and only the outer sheave is moved in the axial direction in a second moving mode.

A drive train for a motor vehicle comprises an internal combustion engine which has a crankshaft and is designed to provide drive power for the motor vehicle. A clutch arrangement has an input member and at least one output member, the input member being connected to the crankshaft. A transmission arrangement implements a plurality of gear stages, the transmission arrangement having a transmission housing, at least one input shaft, and at least one output shaft. The output shaft is connectable to driven wheels of the motor vehicle. An electric machine is designed to provide drive power for the motor vehicle and is connected to a transmission shaft of the transmission arrangement. The transmission shaft has a shaft section which extends from the transmission housing and is connected to the electric machine via a traction drive mechanism.

A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element configured to receive a screw, a rotating outer element that is mounted to rotate coaxially about the fixed inner element and is intended to cooperate with the transmission element, and an annular protective flange bearing against a lateral surface of the fixed inner element. The fixed inner element provides a sleeve axially protruding from the lateral surface. The flange provides an inner axial portion mounted securely on an outer surface of the sleeve.

A transmission for a motor vehicle includes an electric motor and a flexible traction drive mechanism which includes a first traction mechanism wheel, such as, a gear or pulley, which is rotationally fixed to a rotor shaft of the electric motor, a second traction mechanism wheel which can be rotationally fixed to a transmission component and which is drivingly connected to the first traction mechanism wheel by a traction mechanism, such as, a belt or chain, and a bearing journal for supporting the first traction mechanism wheel. An oil line extends through the bearing journal, and oil can be fed to the electric motor via the oil line.
