A drive assemblage is described for a vehicle drivable by muscle energy and/or&#x2014;in particular additionally&#x2014;by motor energy, to an electric bicycle, e-bike, or pedelec, having: a crank spindle rotatable around a rotation axis for receiving a first torque that is generated in particular by muscle energy; and a transfer device that is embodied to transfer the first torque from the crank spindle to an output drive element couplable to a drive wheel of the vehicle, and is embodied, by way of an&#x2014;in particular automatically&#x2014;shiftable spur gear transmission, for a variable conversion ratio, in which: the spur gear transmission has a first shiftable spur gear transmission and a second shiftable spur gear transmission separate therefrom; the first shiftable spur gear transmission and the second shiftable spur gear transmission have a common transmission output to the couplable output drive element; and the first shiftable spur gear transmission and the second shiftable spur gear transmission are couplable alternatingly and alternatively into the power and torque flow of the transfer device.

Drive assembly and vehicle

A bicycle includes an electrical auxiliary drive, including an electric motor, a battery for storing electrical energy, which battery is connected to the electric motor, a crank mechanism having pedal cranks, which are mounted on a pedal crankshaft disposed about a crank axis, so as to be able to rotate, and a planetary gear for driving the bicycle both by the electric motor and by the muscle power of a driver, the planetary gear and the electric motor being disposed about the pedal crankshaft of the crank mechanism.

Hybrid drive for an electric bicycle

A drive system for a pedal-operable vehicle, including a drive motor, pedals on pedal arms, a bottom bracket spindle on which the pedal arms are mounted, and a drive mechanism for transferring drive energy. A clearance is present in a transfer path between a pedal arm and a drive wheel, rotating with the bottom bracket spindle, of the drive mechanism. The system includes a return device with which the clearance-affected parts are transferable, at or below an idle pedal force within their clearance with respect to one another, into an idle position in which the clearance-affected parts assume a predefined relative position; the clearance-affected parts being removable, within the clearance, from the idle position by way of pedal force above the idle pedal force against the action of the return device; and information as to whether the clearance-affected parts are in an idle position being furnishable as electrical signals.

Drive system for a pedal-operable vehicle and method for sensing the state of a pedal drive

A vehicle drivable by motor power and/or pedal power, in particular to an electric bicycle, including: a crank mechanism having a crank spindle; an output drive element that delivers a drive torque for the vehicle, in particular to a chain or the like; an electric drive system having a reduction linkage; and a steplessly adjustable planetary linkage, an output element of the steplessly adjustable planetary linkage transferring the drive torque to the output drive element.

Vehicle with electric auxiliary drive and continuously variable planetary gear unit

A vehicle which is operable by a motor and/or muscular energy, in particular an electric bicycle, which includes an electric motor, a crankshaft drive having a first crank, a second crank, and a crankshaft, a torque sensor for detecting a torque applied by a rider at the crankshaft drive, and a control unit, which is set up to actuate the electric motor based on at least the values acquired by the torque sensor to drive the vehicle, the torque sensor being situated at the crankshaft drive and the torque sensor including at least one surface acoustic wave sensor.

Vehicle which is operable by a motor and by muscular energy and has an improved torque sensor

A method for automatically controlling the gear of a gearshift of an electric bicycle. At least one actual operating parameter of a drive component of the electric bicycle is recorded by recording an operating variable of the drive component. The at least one actual operating parameter is compared to a setpoint default, which reflects an operating point of the electric drive, which is linked to a higher efficiency, a greater reliability or a greater durability of components of the electric drive or of the drive component than in response to an operation according to the at least one actual operating parameter. The at least one actual operating parameter is approximated to the setpoint default by changing the gear. A corresponding device for automatically controlling the gear is also described.

Method and device for automatically controlling the gear of an electric bicycle transmission

An electric motor has a stator and a coil which is arranged within the stator housing and whose winding can be energized via a connection line system. A cooling plate is arranged outside the interior of the stator, and on the outer side of said cooling plate a carrier plate for motor electronics is arranged, to which carrier plate the connection line system is connected. The connection line system is led from the inside to the outside through a recess in the cooling plate and is electrically connected to the carrier plate.

The present invention relates to a heat sink () with a main body () for accommodating at least one electronic structural element (), and with a spring element () for pressing the structural element () against the main body (), whereby the spring element () is held on the main body () by a connecting means. It is provided that the connecting means are configured as a push-on connection () and have a projection () on the main body () and a mounting opening () in the spring element () for the projection (), whereby the opening edge () of the mounting opening () bears, at least in sections, against the lateral surface of the projection () under preload resulting from the intrinsic elasticity of the spring element () and/or the projection ().
