摘要： The disclosure relates to a transmission comprising an input shaft, a first output shaft, a second output shaft, a first planetary gear set, and a second planetary gear set which is connected to the first planetary gear set. Each of the planetary gear sets comprises multiple elements. The input shaft, the two output shafts, the planetary gear sets, as well as the elements thereof are arranged and designed such that—a torque introduced via the input shaft is converted and is distributed to the two output shafts in a defined ratio, and the development of a sum torque is prevented. At least one element of the first planetary gear set is rotationally fixed to another element of the second planetary gear set. Another element of the second planetary gear set is secured to a rotationally fixed component.

摘要： A drive apparatus for an electric-motor four-wheel drive vehicle includes first and second motors, first and second differential mechanisms, and a propeller shaft. The vehicle includes a first wheel pair including first left and right wheels and a second wheel pair including second left and right wheels and positioned on opposite side to the first wheel pair in a front-rear direction. The first and second motors are configured to output first output torque and second output torque, respectively. The first differential mechanism is configured to distribute the first output torque to a first torque-transmitting member coupled to the first left wheel and a third torque-transmitting member coupled to the propeller shaft. The second differential mechanism is configured to distribute the second output torque to the third torque-transmitting member and a second torque-transmitting member coupled to the first right wheel.

摘要： A differential drive system includes an electric motor for generating an electric motor torque and an input planetary gear-set operatively connected to the electric motor to receive the electric motor torque. The input planetary gear-set has first, second, and third members. The first member receives the electric motor torque, the second member provides a first input torque in a first rotational direction in response to the electric motor torque, and the third member provides a second input torque in a second rotational direction, opposite the first direction, in response to the electric motor torque. The system also includes a first output gear-set operatively connected to the input planetary gear-set, and providing a first output torque in response to the first input torque. The system additionally includes a second output gear-set operatively connected to the input planetary gear-set and providing a second output torque in response to the second input torque.

摘要： A differential includes a housing, an internal gear pair having an oscillating gear A and an output gear A, an internal gear pair consisting of an oscillating gear B and an output gear B, at least two A-type intermediate gears, and at least two B-type intermediate gears. Each A-type intermediate gear is radially fixed to the housing, and an axis of rotation of each A-type intermediate gear is parallel to an axis of rotation of the housing. Each A-type intermediate gear is meshed with at least one B-type intermediate gear, and the gear ratio of each gear pair consisting of an A-type intermediate gear and a B-type intermediate gear is the same. Each A-type intermediate gear includes an eccentric shaft having an axis parallel to its axis of rotation, and the eccentric shaft on each A-type intermediate gear has the same distance from the axis of rotation of the gear.

摘要： An integrated planetary gearing system includes a reduction gear and a spur gear differential. First planets are arranged in a first planet plane. Second planets are arranged in a second planet plane. A planetary carrier includes a first carrier wall section, a second carrier wall section, and a third carrier wall section. The first and the second carrier wall section are spaced apart from one another axially and are formed by a base part. The third carrier wall section is formed by a cover element which is attached to the base part. The second carrier wall section carries a plurality of pockets, each receiving a planet of the second toothing plane. The cover element is attached to cover seat faces of the pocket bottoms, which cover seat faces in each case face away from the pocket interior.
