Non-trackbound vehicle with an electrodynamic converter and a throttle

A motor vehicle including a unit (2) consisting of an internal combustion engine, a generator supplying current to electric motors (12, 16) coupled with driving wheels (14, 18) over an energy distributor/power electronics system (8) and a battery which is supplied with energy by the internal combustion engine/generator unit via the energy distributor (2). An electronic control system (20) controls the energy distributor (8) as a function of a driving signal according to boundary conditions, for example, according to the least possible specific fuel consumption. A temporary increase in the power required to drive the motors can be supplied by the battery (22). In the event that the increase in power lasts for longer periods, the internal combustion engine, which as far as possible operates in a state that ensures low fuel consumption, is accelerated in order to cover the demand for high power. At the maximum output of the internal combustion engine, the energy stored in the battery (22) supplies the power for the additional thrust.

Drive system for a motor vehicle

A method for operating a motor vehicle driven by an internal combustion engine, and having a drive train for receiving mechanical power of the engine and imparting motion to the motor vehicle via at least one set of wheels of the motor vehicle, can include a system for engaging and disengaging at least a part of the drive train. This system for engaging and disengaging can be utilized for preventing the motor vehicle from being driven under its own power.

Drive and braking arrangement for a motor vehicle

An apparatus for determining a critical driving torque and information representing the coefficient of friction at the wheel grip limit for a vehicle having a plurality of driven wheels. It is suggested that torque control devices be assigned to at least two of the driven wheels so that the ratio of the driving torques of the two driven wheels can be varied, wherein torque sensing device generate a torque signal corresponding to the magnitude of at least the greater of the driving torques of the driven wheels. A wheel slip sensing device is associated with the driven wheels and detects an increase in the slip of the wheel with the greater driving torque beyond a predetermined limit. The information on the coefficient of friction is generated depending on the magnitude of the detected driving torque of the wheel whose slip exceeds the limit. To determine the information concerning the coefficient of friction, the distribution of driving torque between the front axle and rear axle is periodically increased in an alternating manner.

For controlling a central locking installation and/or theft alarm of a motor vehicle a switch lock installation is provided which comprises at least one lock with mechanical tumblers for the mechanical locking and unlocking of a door or a bonnet of the motor vehicle. The tumblers form a first key secret. The key which blocks the tumblers carries an electrically, magnetically or optically readable information carrier for a second, operationally variable key secret. A reading device detects the information of the second key secret in a position in which the mechanical tumblers of the lock are released. If the key is moved in the opening direction of the lock, a control circuit compares the information read by the reading device with an ideal information stored in a memory circuit and controls the central locking installation and/or theft alarm accordingly. If the key is moved in the closure direction of the lock, then the information of the second key secret read by the reading device is taken as new ideal information into the memory circuit.

The friction disc clutch for a motor vehicle driven by an internal combustion engine comprises a flywheel which is driven through a rotationally elastic element by the crankshaft of the internal combustion engine. The mass-spring system of the drive path of the clutch is so dimensioned that natural vibrations occur in or below the idling rotation rate range of the internal combustion engine. The rotationally elastic element can be bridged over for rotation rates in the range of and below the idling rotation rate in order to prevent resonance effects in idling and in the starting of the internal combustion engine. The bridge-over clutch can be formed by a pinion of the starter motor. Alternatively, centrifugal clutches can be used.

A rotary clutch assembly is provided with a clutch release group. The clutch release group comprises a stator surrounding a torque transmission shaft in driving connection with one of the rotors of the rotary clutch assembly. A first bearing ring surrounds the torque transmission shaft. A toroidal membrane member is fixed with respect to the stator and acts onto the first bearing ring so as to axially displace the first bearing ring in response to pressure variation within the membrane. A second bearing ring is mounted for common axial movement with the first bearing ring and rotatable with respect thereto. The second bearing ring acts onto a clutch disengagement member rotating around the torque transmission shaft.
