A pedal force simulator for a hydraulic brake system of a vehicle has a simulator chamber and a simulator piston that can be moved along a working path within the simulator chamber. The pedal force simulator has a line arrangement by which the simulator chamber can be brought into fluid communication with a pressure chamber of a brake cylinder of the hydraulic brake system. The line arrangement has a valve arrangement, the throttling effect of which depends on the position of the simulator piston along the working path.

Pedal force simulator and brake system

A vehicle has at least one electric machine that can be operated as a generator, an electrical energy accumulator and a control unit for controlling the at least one electric machine and the electrical energy accumulator. The control unit operates so that in a recovery phase the vehicle can be decelerated by the generator load of the electric machine operated as a generator () and the resulting electrical energy (:E) can be stored in the electrical energy accumulator. The control unit is configured so that the at least one electric machine operated as a generator in a recovery phase is operated by said control unit in a chronologically unlimited fashion with a predefinable overload ().

A chassis is provided for a track-guided toy vehicle which is supported on a front axle and a rear axle and has a guide wedge that is movable about a first vertical pivot axle and cooperates with a groove in the raceway. The rear axle is driven by an electric motor, with the rear axle and the electric motor together forming an assembly. Steering capability of the vehicle, is optimized by arranging the assembly to be movable about a second vertical pivot axle. The assembly is operatively connected via a control unit to the chassis-mounted guide wedge.

Chassis for a track-guided toy vehicle

A guide mechanism for a track-guided toy vehicle which is equipped with an electric motor and can be operated on a road surface with a guide groove, engaging with a guide plate in the guide groove via a vertical axis of rotation on a chassis of the toy vehicle by means of a guide mechanism mounted on a chassis of the toy vehicle and being equipped with current collector elements for the electric motor, said collector elements cooperate with current rails in the road surface. A swing arm that is pivotable about a horizontal axis is arranged on the chassis of the toy vehicle which is placed upright on the road surface with the front wheels and rear wheels. The swing arm comprises the guide mechanism with the rotation axis, the guide plate and the current collector elements.

A toy vehicle with an electric drive is provided that is suitable for operation on a racetrack, and has a chassis with a rear-axle unit, including an electric motor, and a front-axle unit. In order to optimize the toy vehicle with respect to the type of construction and driving characteristics, the chassis has a center frame device extending between the rear-axle unit carrying the electric motor and the front-axle unit, on which center frame part, the rear-axle unit and the front-axle unit constructed in the manner of modules are held in position.

Toy vehicle having an electric drive

A toy vehicle is operated as a track-guided vehicle and cooperates with a metallic current rail device of the track via one or more current consumers. A magnet is installed in the toy vehicle which is moved by an electric motor to optimize the traction between the track and the toy vehicle. This magnet is directed at the current rail device of the track. The magnet's magnetic force can be influenced as a function of driving operation states of the toy vehicle driven by the electric motor.

Track-guided toy vehicle

A current collecting device for a toy vehicle for use on an electrified track. The toy vehicle is for operation on a road surface, and is driven by an electric motor installed in a chassis and having a chassis frame that carries the electric motor, whereby the current collecting device has strip-like contact elements which cooperate with current rails of the road surface. The contact elements which are in contact with the current rails of the road surface are carried by a replaceable unit which is connected to the current collecting device.
