Definitions
- the invention relates to a wheel-near drive device for a single wheel of a motor vehicle, comprising an electric drive means with at least one drive shaft for the wheel and a transmission, which with the at least one drive shaft for transmitting torque for driving the wheel
- the invention also relates to a vehicle axle for two wheels of a motor vehicle and a
- the term "close to the wheel” in connection with the drive device preferably comprises neither a wheel hub drive nor a central drive, which drives a plurality of wheels via a transmission.
- a parking brake which secures the vehicle in the stand against rolling away.
- the parking brake In vehicles with manual transmission, it is known to form the parking brake as a so-called handbrake, which is activated by a manually operated parking lever.
- the parking lever is usually provided with a releasable blocking device for fixing the parking lever in at least one parking position, usually in the form of a ratchet-like
- a button is provided at the end of the parking lever.
- a parking brake is provided which can be inserted by means of the gear selector lever in the state of the vehicle and the vehicle in addition to the parking brake against Rolling away secures.
- the parking brake is arranged in the central drive train of the motor vehicle between the engine and axles.
- Locking the wheel is arranged, which is designed to block the transmission and / or the drive shaft.
- the object is also achieved by a vehicle axle having the features of claim 12, by use of a drive device according to claim 14 and by use of a vehicle axle according to claim 15.
- a radnahe drive device for a single wheel of a motor vehicle comprising an electric drive means with at least one drive shaft for the wheel, and a transmission, which with the at least one
- Drive shaft for transmitting torque to drive the wheel cooperates, and which is connectable to the single wheel and the radnahe drive device is characterized in that a locking device for blocking the wheel is arranged, which is designed to block the transmission and / or the drive shaft ,
- a vehicle axle, in particular torsion beam axle, defined for two wheels of a motor vehicle, comprising a torsion, two Trailing arms, which are arranged on different sides of the Torsionsprofils and which are each connected to a wheel for each of the wheels of the motor vehicle and the vehicle axle is characterized in that in each case a drive device is arranged for the wheels, which is designed to drive a single wheel and that the drive device, in particular a gear of the drive device, is designed as a trailing arm.
- vehicle axle according to at least one of claims 12 to 13 can be used in a motor vehicle, in particular in an electric vehicle.
- the wheel near drive device has the advantage that, for example, a setting or freezing of brake shoes of the service brake for each wheel, as occurs in cold weather conditions and older vehicles with internal combustion engine in the parking brake, can be reduced, because part of the holding force is provided by the parking lock.
- Holding force acts only on a wheel of a vehicle axle. This is reliably avoided by the drive device with the features of claim 1, since each one of the wheels is blocked by the locking device as opposed to
- the locking device comprises a pawl and a
- Gearing which can be brought into engagement for blocking.
- the advantage of this is that thus in a simple and reliable way blocking the transmission and / or the drive shaft is made possible.
- the toothing can for this purpose arranged directly or indirectly on the drive shaft or in the transmission itself.
- Another advantage is that the locking device can be produced inexpensively.
- the locking device is electrically actuated.
- an electromechanical, electropneumatic, or other type of actuation of the locking device is at least partially covered by electrical means.
- the operation of the locking device in the passenger compartment of the motor vehicle can be done by means of a simple switch, so that mechanical levers, as common in motor vehicles with automatic transmission for a parking brake, can be omitted.
- This can also be saved building space in the center tunnel of the passenger compartment. This can then be used for operation of navigation systems, multi-media systems, etc.
- a, in particular electrical and / or mechanical, energy storage is arranged, which cooperates with the locking device for their actuation.
- the reliability of the locking device is further increased because, for example, in the event of a power failure in an on-board electronics of the motor vehicle, an operation of the locking device is still possible.
- the locking device is arranged on the drive shaft of the electric drive means.
- the load acting on the locking device vehicle load is reduced by the wheel to the disposed between the locking device and wheel gear, so that the locking device has a lower holding force must be provided as would be required in a direct loading of the locking device on the wheel. If the locking device is actuated, all gears, bearings, etc. of the transmission are loaded and ultimately reduce the by the
- Locking device to be applied holding force for the wheel.
- the transmission comprises at least one translation device.
- the transmission comprises at least one translation device.
- the advantage thus achieved is that thus the locking device is insensitive to external environmental influences and so the life of the locking device can be increased.
- the locking device can be integrated into a lubrication circuit of the transmission in a simple manner, without a large number of additional channels, etc. must be arranged for the lubrication of the locking device.
- the locking device is arranged on the side facing away from the translation device of the drive shaft.
- the locking device disposed at the end of the drive shaft of the electric drive means, the locking device is easily accessible from the outside and can therefore be easily maintained. Moreover, this can be done in a simple way already existing
- the locking device is arranged on the at least one translation device.
- the respective toothings and / or gears, etc. of the translation device can be used to form the locking device at least partially.
- no additional component is required to block the drive shaft. This reduces overall the manufacturing cost of the drive device. So it is possible, for example, the corresponding teeth for a locking device in a translation device in the form of a planetary gear through a web of the planetary gear
- the locking device is arranged on an output shaft of the at least one translation device.
- the other transmission components between the transmission device in the transmission for example, when the output shaft is mounted directly on the wheel bearing and the locking device is arranged on this output shaft, the other transmission components between
- Locking device and drive shaft load-free which significantly increases the life of these transmission components. If the locking device is arranged on the transmission device, which is connected directly on one side to the drive shaft of the electric drive means, a low holding force is required to lock a wheel through the locking device, since further transmission components between the locking device and the wheel are arranged and this for the Blocking and / or holding a wheel of the motor vehicle reduce necessary holding power.
- the at least one translation device is a
- Planetary gear and / or designed as a pinion-Stirnrad- arrangement In this way, extremely reliable translation devices can be provided depending on the application requirements for the drive device.
- the drive device of the vehicle axle according to claim 12 according to at least one of claims 1 - 1 1 is formed.
- Vehicle axle with drive and locking device for a near-wheel drive of a motor vehicle in particular an electric vehicle, can be provided without further components for a locking device in the form of gear, tunnels or the like must be provided. This allows a cost-effective production of a vehicle axle with drive device and
