20110233888 | TRANSVERSE LINK FOR A WHEEL SUSPENSION - A transverse link for a wheel suspension, which can be connected to a suspension point of a car body or of a chassis and a holding point of a wheel mount. The transverse link has a connecting rod on the wheel mount side and a connecting rod on the vehicle side, which are connected to one another in a rotating manner. The connecting rod on the vehicle side can be fastened on the suspension point of the auto body or of the chassis and the connecting rod on the wheel mount side can be fastened to the holding point of the wheel mount. Such a transverse link can be used both on the front and rear axles. The plurality of variable parameters permits fine coordination with regard to kinematic travel properties. Also, a low number of additional components are required. | 09-29-2011 |
20110290554 | APPARATUS FOR ADJUSTING ENVIRONMENTAL CONDITIONS FOR AN ELECTRICAL COMPONENT - An apparatus for adjusting substantially constant environmental conditions for an electrical component, which conducts and/or stores current. The electrical component is surrounded by a housing, which has an opening to obtain a connection to the external environment of the housing. The housing has means, which protect the electrical component substantially from dirt, dust and/or moisture from the external environment. | 12-01-2011 |
20120242137 | ELECTRICAL DRIVE UNIT FOR A MOTOR VEHICLE - An electrical drive unit for a motor vehicle, with the drive unit including a wheel hub drive that drives a vehicle wheel. The wheel hub drive has a sealing element which is affected by friction and by means of which the interior of the wheel hub drive is sealed off from the surroundings in an airtight manner. A ventilation device is provided by which a pressure difference between the prevailing air pressure in the interior of the wheel hub drive and the prevailing air pressure of the surrounding air can be compensated by displacing volumes of air. | 09-27-2012 |
20120242197 | ELECTRICAL DRIVE UNIT FOR A MOTOR VEHICLE - An electrical drive unit for a motor vehicle, with the drive unit including a wheel-hub drive that drives a vehicle wheel and that is arranged on the vehicle wheel by a wheel bearing, the wheel-hub drive having a rotor and a stator. According to the invention, a sealing device is provided between the rotor and the stator, and/or between the rotor and a component adjacent to the rotor, and/or between the stator and a component adjacent to the stator. A sealing surface of the sealing device is arranged on a radius with the center point around a virtual tilt axis of the wheel bearing, or substantially along a tangent to the radius. | 09-27-2012 |
20120248849 | WHEEL HUB DRIVE UNIT - A wheel hub drive unit for driving a motor vehicle wheel, with the unit including a wheel hub drive that has a bearing element ( | 10-04-2012 |
20130037331 | MOVABLE SYSTEM - A displaceable system including at least one set of at least two wheels arranged in pairs for movement in a plane, said set being disposed on at least one wheel axle parallel to the plane. A single electric drive motor, a differential having variable torque distribution, and an electric servomotor are provided on the wheel axle for both wheels of a set. The electrical servomotor acts on the differential such that the torque generated by the single electric drive motor is distributed within the wheel axle individually to the wheels. | 02-14-2013 |
20130060437 | SAFETY CLUTCH FOR AN ELECTRIC DRIVE AND USE OF THE SAFETY CLUTCH IN A WHEELED VEHICLE - A safety clutch for an electric drive which includes an electric motor and a shaft which is driven thereby. A transmission of torque between the electric motor and the shaft can be brought about by at least one connecting element. A controllable locking device via which an interruption in the transmission of torque between the electric motor and the shaft can be brought about, is assigned to the connecting element. The use of the safety clutch in an electric drive for a wheeled vehicle is disclosed, a controller evaluating the transmission of torque between the electric motor and the shaft using a vehicle state, and when a fault state is detected the controller transmitting a control signal to the controllable locking device, as a result of which an interruption is brought about in the transmission of torque between the electric motor and the shaft. | 03-07-2013 |

20140077634 | COOLING JACKET AND DEFLECTION UNIT FOR COOLING JACKETS - A cooling jacket ( | 03-20-2014 |
20140103783 | DRIVE SYSTEM HAVING A BEARING TILT DETECTION SYSTEM, AND ELECTRIC OR HYBRID VEHICLE HAVING THE SAME - A drive system, in particular for an electric and/or hybrid vehicle, including a static part (S) and a rotatably mounted part (D) and also an electric motor with a stator ( | 04-17-2014 |
20140117744 | STATOR HOLDING PLATE WITH INVERTER FASTENING FUNCTION - A stator holding plate ( | 05-01-2014 |
20140151002 | SHIELDING PLATE HAVING A COOLANT LINE - An electromotive drive system, especially an electric wheel hub drive, for example, for an electric and/or hybrid vehicle. In order to protect heat-sensitive components of the electric motor against heat input stemming from a friction brake, the drive system includes a shielding device ( | 06-05-2014 |
20140152076 | WHEEL HUB DRIVE SYSTEM - A wheel hub drive system with an electric motor that can be arranged inside a wheel rim, whereby the electric motor is formed by rotor that is at least indirectly joined to a wheel hub and by means of a stationary stator that can be supplied with alternating current. With an eye towards obtaining more space for the vehicle occupants, it is proposed to arrange the converter with its entire power electronics unit on the stator so that the wheel hub drive system can be operated with direct current from the battery of the vehicle, or else no alternating current lines have to be laid in the vehicle. Consequently, the alternating current is generated by the converter that is arranged in a converter housing attached axially next to the stator. | 06-05-2014 |
20140374185 | ELECTRIC POWER TRAIN FOR THE STEERABLE AXLE OF A MOTOR VEHICLE - A power-train is provided for a driven, steerable axle of a motor vehicle. To reduce the size of the turning radius of the vehicle, the power train includes a left drive shaft that is fixedly connected in terms of drive to a left steerable wheel; a right drive shaft that is fixedly connected in terms of drive to a right steerable wheel; and a drive unit configured between the drive shafts for driving the drive shaft; the drive shafts being configured as articulated shafts, each having a wheel-proximal articulated joint and a wheel-distal articulated joint; and said articulated joints each having at least one axis of rotation with the same orientation for all articulated joints. The drive unit is designed for transmitting an electromotively generated torque to the drive shafts, and having a body suspension that allows the drive unit to rotate relative to the body about a swivel axis that extends in parallel to the axes of rotation having the same orientation. | 12-25-2014 |
