An electrically motorized driving wheel for vehicles such as bicycles is provided. The electrically motorized wheel can include a wheel rim, a housing disposed inside and connected to the wheel rim, wherein the housing defines an installation space inside the housing, a driving force generating mechanism disposed in the installation space, and a driving force transfer mechanism connected to the driving force generating mechanism and configured to transfer a driving force generated from the driving force generating mechanism to the housing.

A drive unit for a vehicle includes a drive unit spindle. The drive unit spindle extends along an axis for connecting the drive unit to the vehicle. The drive unit further includes one or more wheel assemblies. Each of the wheel assemblies has a hub that is removably supported by the spindle along the axis. At least one of the wheel assemblies includes a wheel which rotates about the hub and a motor connected to the wheel to rotate the wheel about the hub.

A method of thermal management for an electrically motorized wheel, the method can include defining a thermally conductive path from at least one component, the at least one component becoming heated during operation of the electrically motorized wheel, providing the path with a thermally conductive material and further defining the path such that the path contacts the at least one component, further defining the path such that the path contacts a hub shell assembly of the electrically motorized wheel thereby conducting heat from the at least one component to the hub shell assembly.

A powered unicycle device has a hub motor and a tyre around the motor. A motor casing around the motor defines side walls (300,305) and an outer annular rim (301,306), and the tyre is mounted around the outer annular rim (301,306). The motor casing is formed of only two side walls (300,305) each having a rim portion (301,305), and the rim portions (301,305) connect to each other, together defining the outer annular rim (301,305).

A refuse vehicle including a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, and an electric energy system, the electric energy system including one or more battery cells and control hardware, the electric energy system detachably coupled to the body and configured to be accessed by a door in the body, and wherein the one or more battery cells of the electric energy system are replaceable.

A wearable motorized device comprising a shoe bracket, which can be fastened to a shoe; wheels that are installed on the left and right sides of the shoe bracket in parallel to support the wearer's lateral skating and longitudinal walking; a driving motor for rotationally driving the wheels; and a battery pack for powering the driving motor. The wheels are not coaxially installed on the two sides of the shoe bracket to drive the wearer's longitudinal skating, but instead are installed on the two sides of the shoe bracket in parallel to drive the wearer's lateral skating; the wearer can position his/her legs apart during skating, so the skating stability is improved. Its general contour does not significantly exceed the contour of the shoe in the longitudinal direction, thus and it will not strain the wearer when ascending or descending stairs.

The invention relates to a vehicle including a chassis and a pair of wheels supported in spaced apart relationship by the chassis for rotation about a common axis. A pair of drive modules is associated with the respective wheels. The drive modules and the chassis are connected for rotation as a sub-assembly relative to the wheels about the common axis with the centre of mass of the sub-assembly below the common axis in a static equilibrium position. Each of the drive modules is housed substantially within the respective wheel.

A refuse vehicle includes a chassis, a body assembly, and battery cells. The body assembly is coupled to the chassis and defines a refuse compartment. The battery cells are positioned between the body assembly and the chassis.

A refuse vehicle including a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, and an electric energy system, the electric energy system including one or more battery cells and control hardware, the electric energy system detachably coupled to the body and configured to be accessed by a door in the body, and wherein the one or more battery cells of the electric energy system are replaceable.

A structure for mounting a battery and a spare tire may include a battery bracket fixing the battery to an accommodating compartment recessed in a rear floor of a vehicle, and a tire mounting bracket fastened to the spare tire, disposed at an upper side of the battery, through a tire bolt, and fixing the spare tire to the rear floor, in which the battery bracket and the tire mounting bracket are separated so that a load applied to the spare tire is not transmitted to the battery.
