摘要： A drivetrain 2 for a vehicle with an electric propulsion motor 4 having a hollow rotor shaft 9 comprises a transmission 100 with at least a hollow first shaft 24 and a bifid second shaft 28 being a countershaft. The drivetrain 2 comprises a parking lock 70 and a differential 76 connected with two output shafts 84, 90. Rotational speed of the first shaft 24 is reduced by a transmission stage 14, 16, 17 formed by at least two gearwheels 50, 52, a first gearwheel 50 fixed to the first shaft 24 and a second gearwheel 52 fixed to the second shaft 28, and a planetary transmission 17. The first gearwheel 50 is a sun gear of a planetary transmission 17. A disconnect 60 is part of the bifid second shaft 28, which is arranged to be switched into a disconnected state while a prevailing torque is introduced from a secondary side. The first shaft 24 and the rotor shaft 9 are connected with each other and supported in a coaxial shaft arrangement by a common bearing arrangement 98.

摘要： The disclosure relates to a differential gear assembly (20) comprising a ring-shaped gear (26) being rotatable around an axis (A) and a bevel gear unit (44) with four bevel gears (48a, 48b, 48c, 48d) being supported on a bevel gear carrier (46). Two bevel gears (48a, 48b, 48c, 48d) are additionally supported on a cross shaft (60). The ring-shaped gear (26) comprises at least two primary contact surfaces (38a, 38b) having a spherical shape and the bevel gear carrier (46) comprises at least two secondary contact surfaces (56a, 56b) having a spherical shape. Each of the secondary contact surfaces (56a, 56b) contacts an associated primary contact surface (38a, 38b). Moreover, two reception slots (40a, 40b) are arranged on the ring-shaped gear (26) and an end (62a, 62b) of the cross shaft (60) is received in each of the two reception slots (40a, 40b) such that the ends (62a, 62b) and the reception slots (40a, 40b) form a positive locking being effective in a circumferential direction of the ring-shaped gear (26). Additionally, a drivetrain for a vehicle comprising such a differential gear assembly (20), a method for assembling a differential gear assembly (20), and a method for disassembling a differential gear assembly (20) are explained.

摘要： The present disclosure provides a differential gear to be mounted on a vehicle, including a pair of side gears, at least two pinion gears meshed with the side gears, and a differential case that houses the side gears and the at least two pinion gears. Lubricating oil is supplied to and discharged from the inside of the differential case via an opening portion. The differential case includes at least two seat surfaces formed on the inner peripheral surface of the differential case so as to support the pinion gears, weir portions provided between the adjacent seat surfaces and extending in a direction along the rotational direction of the differential case to connect between the adjacent seat surfaces, and an oil reservoir portion formed on the inner peripheral surface by the weir portions so as to be positioned on the opposite side, in the axial direction of the side gears, of the opening portion from the weir portions. Consequently, it is possible to render the differential gear compact by suppressing a shortage of lubricating oil for a sliding portion well.
