Abstract: 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.

Abstract: An electric all-terrain vehicle includes a set of wheels, a drive system, a battery pack, and an MCU. A projection of the MCU, a projection of the battery pack, and a projection of the electric motor all on a horizontal plane cooperatively define a Tri-core system projection area with a Tri-core longitudinal length. A ratio of the wheelbase distance to the Tri-core longitudinal length is in the range from 0.7 to 2.5. The positions of the Tri-core system are reasonably arranged and the relevant components are highly integrated, the center of gravity of the entire vehicle are reasonably allocated, thereby making the overall performance of the vehicle more superior and achieving better driving performance.

Abstract: Aspects of the disclosure provide a terminal device that includes an interface circuitry and a processing circuitry. The interface circuitry is configured to interface the terminal device to a network, and transmit and receive signals to/from a server and other terminal devices via the network. The server provides service functionality to users who are registered with the server in a service network. The terminal device is utilized by a first user who is registered in the service network, and is associated with one or more friend users in the service network. The processing circuitry is configured to cause the interface circuitry to send a first application request to a second terminal device that is utilized by a friend user, receive a first response that is generated based on a first input on the second terminal device in response to the first application request, and receive a processing result of the first application request that is determined by the server based on the first response.
