    Abstract: This application provides a powertrain and an electric vehicle, relating to the field of motor technologies. In the powertrain, two driving motors are disposed in parallel. To prevent occupying space of a passenger compartment, a battery pack, a trunk, and the like, reserved space for disposing the powertrain on an existing mainstream vehicle is more on one side relative to a wheel shaft. Therefore, in the powertrain designed in this application, when two reducers respectively mesh with the two driving motors, neither output shafts of the two reducers are on a plane that is perpendicular to a connection line of centers of the two driving motors and at a contact position between the two driving motors. In other words, the two output shafts are disposed on one side of the entire powertrain, so that the powertrain can be disposed on a mainstream vehicle, and adaptability of the powertrain is improved.

    Abstract: Embodiments of the present disclosure provide an autonomous mobile robot and a walking method thereof. The autonomous mobile robot includes a machine body, a driving wheel assembly and an obstacle crossing assembly. The driving wheel assembly is rotatably arranged on the machine body through a first rotating shaft. The driving wheel assembly includes a driving wheel. When the driving wheel moves from a first position to a second position relative to the machine body, the obstacle crossing assembly applies a force to the driving wheel assembly to make a change amplitude of positive pressure between the driving wheel and a traveling surface less than or equal to a set threshold value.

    Abstract: A driving system includes an electric motor, a transmission apparatus, a differential apparatus and a brake. The differential apparatus includes an input portion coupled to an output portion of the transmission apparatus, a pair of output portions, and a differential device that allows differential rotation of the pair of output portions. A brake is provided in a drive path from an output portion of the electric motor to the input portion of the differential apparatus. The differential apparatus includes a clutch member movable between a first position in which a differential rotation of the differential device is allowed and a second position in which the differential rotation of the differential device is stopped, a clutch actuator that moves the clutch member to the first position, and a holding portion that holds the clutch member to the second position when the clutch actuator is in a non-operating state.

    Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support frame to influence motion of the patient transport apparatus over a floor surface. The auxiliary wheel is movable to a deployed position with the auxiliary wheel engaging the floor surface and a stowed position with the auxiliary wheel spaced a distance from the floor surface. An actuator assembly including a lift actuator a biasing device, and a biasing load adjustment assembly. The lift actuator is operable to move the auxiliary wheel to the deployed position and to the stowed position. The biasing device configured to bias the auxiliary wheel towards the deployed position. The biasing load adjustment assembly configured to adjust a biasing force being applied by the biasing device to the auxiliary wheel.

    Abstract: An in-wheel motor drive device includes an electric motor section, a speed reducer section, a wheel bearing section, and a casing. The speed reducer section includes a speed-reduction structure using a parallel shaft gear. The parallel shaft gear includes an input shaft, which is coupled to the electric motor section, an input gear, at least one intermediate shaft including input-side and output-side intermediate gears, an output shaft, which is coupled to the wheel bearing section, and a final output gear. The input, intermediate, and output shafts are supported by rolling bearings to be rotatable. At least two rolling bearings configured to support the intermediate and output shafts on an out-board side and two rolling bearings configured to support the intermediate and output shafts on an in-board side are arranged at positions at which respective bearing widths are prevented from being superimposed with each other in an axial direction.
