A drive module assembly for use in a vehicle includes a housing defining a housing interior and an electric machine. The electric machine includes a rotor and a stator. The drive module assembly includes a first input shaft, a second input shaft, a first output shaft, a second output shaft, and a differential disposed downstream of at least the rotor. The drive module assembly also includes a gearset, a clutch, and a park lock. The gearset, the clutch, and the park lock are disposed downstream of the differential such that the gearset and the clutch are configured receive rotational torque from the differential through the first and second output shafts.

A vehicle differential includes: a pair of side gears arranged in a differential case; a plurality of friction plates arranged on an axially outer side of respective one of the side gears; and a pressing member that holds the plurality of friction plates together with respective one of the side gears. Each of the side gears has: a gear section that meshes with a pinion gear; and a cylindrical section s that extends from a radially inner portion of the gear section toward an axially side. outer An outer circumferential portion of the cylindrical section meshes with an inner circumferential portion of the pressing member via a helical spline.

A front differential includes an outer ring spline mounted on an inner housing for rotation with the ring gear joinder, an inner ring spline mounted on one of the semi-axle gears, and a plurality of friction members disposed between the inner ring and the outer ring. The friction members are interleaved plates which can create a partial friction state and a fully locked state of the front differential through application of axial pressure force. The spline mounting of the inner and outer rings allows axial movement so the axial pressure force application is more accurate despite manufacturing tolerances. A ball bearing is arranged between the differential housing and the ring gear joinder. The ball bearing is connected to the differential housing by a clearance fit which allows the ball bearing to move axially relative to the differential housing.

A driving apparatus for an electric vehicle includes a first motor transmits driving torque to the wheels on both sides, and including a first motor shaft of a hollow shaft, a second motor disposed parallel to the first motor, an output shaft coaxially disposed with a second motor shaft of the second motor, a first reduction mechanism including a first planetary gear set disposed on one driveshaft, including first, second, and third rotation elements, a second reduction mechanism including a second planetary gear set disposed between the second motor shaft and the output shaft, which includes fourth, fifth and sixth rotation elements, and reduces speed of torque input from the second motor and outputs to the output shaft, and a third reduction mechanism including an output gear fixed to one side of the output shaft and the differential ring gear engaged with the output gear.

A vehicle controller for reducing noise of a differential gear of a vehicle, the vehicle including: a ring gear teeth-engaged with a motor reducer, a differential case connected to the ring gear, a differential assembly including a differential gear provided inside the differential case, and a disconnector device connected to at least one gear among the differential gears, the vehicle controller including: an RPM measuring unit for measuring a speed of one vehicle wheel when the vehicle is driven by two wheels; a speed calculation unit for calculating a speed of the ring gear in consideration of the speed of the one vehicle wheel; and a driving unit for driving the ring gear by controlling the motor reducer based on the speed of the ring gear.
