Abstract: A control device for a scooter and a scooter for transporting individuals are provided. The scooter is operable using physical strength in a first mode of operation while being operable using physical strength and/or electric power in a second mode of operation. The scooter has an operating device for a control unit, and an electric motor which allows the scooter to be powered. A propulsive force is created on the scooter by actuating the operating device.

Abstract: A single-track scooter for transporting people is provided. The scooter includes a front wheel and a rear wheel (arranged one behind the other in the longitudinal direction of the scooter, a fork for holding and guiding the front wheel, a rear wheel mount and a frame formed in three parts. The frame includes a fork mount, a middle part and a rear wheel mount. The fork mount can rotate relative to the middle part about a first axis of rotation and the rear wheel mount can rotate relative to the middle part about a second axis of rotation, with the axes of rotation being arranged at an acute angle to the longitudinal axis of the scooter.

Abstract: A frame assembly is provided for a two-wheeled vehicle, in particular for a bicycle, including: a main frame, which has a head tube for connecting to a front wheel mount and a saddle connection for connecting to a saddle; and a drive-train swing arm pivotably connected to the main frame. The drive-train swing arm includes a wheel suspension for a rear wheel to be driven and a pedal-crank drive having a pedal crank for driving the rear wheel by muscle force of a rider. The pedal-crank drive is associated with the drive-train swing arm. The drive-train swing arm is pivotably connected to the main frame by a multijoint assembly.

Abstract: A mounting device is provided for oscillatingly mounting a range extender, which consists of an internal combustion engine and a generator, on a body and/or a chassis of a motor vehicle by way of vibration-damping elements. At least two of the vibration-damping elements are integrated in load-carrying bearings and one additional one is integrated in a supporting bearing for supporting moments. The mounting device is characterized in that the vibration-damping elements of the mounting device at least for the load-carrying bearings are secured to the range extender, i.e. a first vibration-damping element is secured to the internal combustion engine and a second vibration-damping element is secured to the generator.

Abstract: In a method for the damping force adjustment of motor vehicles in dependence of output signals of a transmitter arranged at the vehicle body which are processed and are compared with a predetermined threshold value and which produce a signal for changing the damping force when exceeding/dropping below this threshold value, the changes of these output signals are added at equal intervals with respect to time and determined over a measuring period which is considerably larger than the natural period (reciprocal resonance frequency) of the vehicle wheels and are compared with a threshold value which is dependent on the load of the vehicle. A drift-free indication about the damping force adjustment to be selected becomes possible therewith without frequency analysis.
