Abstract

Electric in-wheel motors to date are made by installing a typical electric motor on a wheel. The said motor includes the stator, rotor and tire rim connected together by a sealed bearing.
In this invention the motor bearing is eliminated and the stator and rotor are attached to separate rims: the rotor rim is sandwiched between the tire rim and the brake, and the stator rim is sandwiched between the suspension frame and the brake. In this way the installation and construction of the motor is simplified by using the existing bearing of the wheel. The stator, being the fixed part of the motor containing the coils is sealed separately from the rotor containing the magnets.
The motor is designed on an open and simple architecture that eliminates bearings, bearing seals, cooling liquid access thru the bearing core, and allows for a simple method of heat dissipation.

Description

Disclosure This invention relates to the electrical propulsion of a vehicle wheel.

Electric in-wheel motors typically includes the stator, rotor and tire rim connected together by a sealed bearing that keeps the dirt and water out and keeps the cooling liquid in.

In this invention the motor bearing is eliminated and the stator and rotor are attached to separate rims that get sandwiched between the tire rim and the brake for the rotor, and the suspension frame and the brake for the stator, so the installation and construction of the motor is simplified by using the existing bearing of a wheel. Air, dirt and water are allowed to flow around the stator and rotor being both surrounded by a jacket of metal or polymer. The cooling of the coils happens in the jacket surrounding them in the fixed part of the motor and tubes of coolant medium are attached to the said jacket.

The said invention proposes to simplify the conversion to electric propulsion of a gas driven car, or the adaptation of electric propulsion of new vehicle, and provide the advantages of parallel hybrid and plug-in hybrid and pure electric propulsion to that vehicle, including the use of economical and efficient electrical driven power, zero emission and regenerative braking.

Figure 1 of the drawings show the cross section of the embodiment while figure is a detailed partial cross section. Figure 3 and 4 shows alternate arrangements of the in-wheel motor. Figure 5 is an isometric exploded view of the said motor and figure 6 is an isometric partial section of the in-wheel motor assembly with the stator jacket and brake not shown for clarity.

As shown in figure 1 and 2, the said in-wheel motor comprises of a stator (6) containing coils and a cooling jacket (7), which is attached to an interior, fixed rim (stator mount 8) bolted-on between the suspension frame (wheel mount 9) &
the fixed drum brake (5). The rotor (2) containing magnets are attached to a rim (rotor mount 4) bolted-on between the wheel rim (1) & the drum brake (5).

The magnets (rotor 2) are arranged in a circular flat ring concentric and peripheral to the drum brake (5) and are attached to a circular mount plate (rotor mount 4), sandwiched between the rim (1) and the drum rotating brake housing (5).

The stator (6) is a sealed brush-less array of coils and steel, concentric and peripheral to the rotor magnets (2), arranged in a thin ring with a cooling jacket (7) surrounding the outer layer, attached to a circular plate with spokes that attaches the stator (stator mount 8) between the wheel suspension arm bearing mount (wheel mount 9) and the drum brake fixed housing (5).

The rotor magnets (2) are sealed from the elements with a metal or polymer jacket (3) independently form the fixed stator (6), which in turn is sealed with a metal or polymer jacket (7) that contains the cooling liquid or fan forced air, which is flowing between the sealed coils. An edge on the periphery of the rotor restricts the entry of particles between the rotor and stator.

The cooling liquid or fan forced air is channeled to a close circuit conduit (10) attached to the outer perimeter of the stator (6) and linked to a typical fan-cooled radiator or a fan for air cooling. The said cooling jacket (12) is situated in the hottest point of the motor, while the magnets (rotor 2) and mechanical brake (5) are cooled by the surrounding air. The liquid or air in the fixed cooling jacket is easily conducted with tubes (10) to a cooling unit (not shown) without having to pass thru rotating seals. Similarly the electric wires (11) off the coil extremities arranged a ring are easily connected to a control box (not shown).

In figure 3, the said in-wheel motor is arranged in the same manner as previously described except that the rotor (2) is peripheral to the stator (6).

In figure 4, the said in-wheel motor is arranged in the same manner as in figure 3 except that the rotor (2) is attached to a ring (4) concentric and peripheral to stator (6) that is attached to the tire rim (1) or is part of the said rim.

The proposed wheel-motor simplifies the manufacturing, mass-production, and installation of electric wheel propulsion, eliminating some major motor components and maintenance while using the existing rolling elements of the wheel.
