A mobile vehicle is disclosed herein. It comprises a car body having four wheels and a chassis bracket at a bottom thereof, and at least one drive motor disposed on a front side or a rear side or both of the chassis bracket and each of which has a motor body and a rotational shaft passing through a center of the motor body for driving the four wheels to rotate through a driver assembly.

An electric vehicle comprises a vehicle chassis extending along a longitudinal axis and a rotatable vehicle drive axle disposed along a transverse axis and having opposed ends that are configured for attachment of a pair of opposed drive wheels. The electric vehicle also comprises a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis, the electric propulsion motor configured to be mounted within the vehicle chassis and operatively coupled to the rotatable vehicle drive axle and opposed drive wheels, the motor axis configured to be oriented in a substantially vertical direction.

An electric or hybrid electric vehicle comprises a vehicle chassis extending along a longitudinal axis and a rotatable vehicle drive axle disposed along a transverse axis and having opposed ends that are configured for attachment of a pair of opposed drive wheels. The electric vehicle also comprises a selectively movable electric propulsion motor comprising a rotatable motor shaft rotatable about a motor axis, the electric propulsion motor configured to be mounted within the vehicle chassis and operatively coupled to the rotatable vehicle drive axle and opposed drive wheels, the motor axis configured to be oriented in a substantially vertical direction, a selectively movable differential disposed on the drive axle and configured to operatively couple motive power of the electric propulsion motor that is transmitted to the rotatable motor shaft to the drive axle, and a motor actuator operatively coupled to the electric propulsion motor and the vehicle chassis.

An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.

The inventive subject matter provides apparatus, systems and methods in which a suspension strut is integrated with a motor. The suspension strut preferably includes a damper having a tube and a piston, which damper can be partially disposed below the motor, or within the motor. Wires providing electrical power to the motor are preferably positioned such that the wires do not contact the coil spring. It is also contemplated that the suspension strut can comprise a multi-stage reduction gear, and independently, can include an oil reservoir, oil circulation pump, and oil distribution pathway configure to cool the motor.

An autonomous mobile vehicle includes an automatic guided vehicle (AGV), a platform assembly coupled to the AGV, and a collaborative manipulator mounted to a support plate of the platform assembly. A safety sensor is coupled to the collaborative manipulator and includes a first proximity sensor fixed relative to the support plate and a second proximity sensor coupled to the collaborative manipulator proximate to a gripper of the collaborative manipulator and movable with an arm of the collaborative manipulator. The safety sensor determines when the gripper is located at a home position proximate to the support plate by detecting the second proximity sensor in proximity to the first proximity sensor.

A power transmission device for a commercial vehicle having an electric axle, may include a first differential ring gear fixedly mounted on a first rear-wheel driveshaft; a second differential ring gear mounted on a second rear-wheel driveshaft; a propeller shaft, with a first differential drive gear engaged with the first differential ring gear being connected to a front-end portion of the propeller shaft and a second differential drive gear engaged with the second differential ring gear being connected to a rear end portion thereof; a reducer connected to the first differential ring gear or the propeller shaft; and a motor, an output shaft of the motor being connected to an input gear of the reducer.

A low-profile vehicle chassis comprising at least one chassis section comprising an upper side, a lower side spaced from the upper side and a cavity defined between the upper and lower sides of the chassis. At least one drivetrain and/or power component of the vehicle is contained within the cavity. Also, a vehicle comprising such a chassis. Also provided is a drivetrain module for an electric vehicle, the drivetrain module comprising a housing, at least one electric motor within the housing, a gearbox within the housing and having an input connected to the at least one electric motor to receive drive from the at least one electric motor, and at least one drive shaft connected to an output of the gearbox to transmit mechanical drive from the gearbox.

A leg structure of a quadruped robot includes a body and four separate leg modules. Each leg module includes a thigh motor assembly, a calf motor assembly, a hip joint motor assembly and an associated linkage and fixing base of the hip joint motor assembly. The hip joint motor drives the thigh and calf assembly through a parallelogram mechanism, the thigh motor assembly directly drives the thigh rod assembly, and the calf motor assembly drives the calf assembly through an anti-parallelogram mechanism. The joint motor assemblies are independent of each other and all the motor assemblies are modularized; the thigh and calf motor assemblies have a good ability to prevent external impact, and the joints on the robot body, formed by using the motor assemblies, have a large working space, thus ensuring the movement flexibility of the robot.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.
