Abstract
Disclosed is an electric power steering system for a vehicle, the power steering system including: an electric motor configured to provide mechanical power to a steering mechanism of the vehicle for steering the vehicle; a housing in which the electric motor is disposed, wherein the housing comprises an inner housing in which the electric motor is disposed, and an outer housing disposed around the inner housing, and wherein an air flow path is defined within the housing, the air flow path being defined at least in part by a gap between the inner housing and the outer housing; and an air flow source arranged to generate an air flow along the air flow path to cool the electric motor, wherein the air flow source is independent from the electric motor.
Claims19
An electric power steering system for a vehicle, the electric power steering system comprising:
- an electric motor configured to provide mechanical power to a steering mechanism of the vehicle, the steering mechanism adapted to steer the vehicle;
- a housing comprising an inner housing and an outer housing, the inner housing having said electric motor disposed therein, said outer housing being disposed around the inner housing, wherein a gap between the inner housing and the outer housing defines an air flow path;
- and
- an air flow source arranged to generate an air flow along the second fixed part so as to cool said electric motor, said air flow source being independent from said electric motor, wherein said electric motor has a first electric motor and a second electric motor, wherein both of the first electric motor and the second electric motor are disposed in said housing and configured to respectively apply a torque to a common shaft used to steer the vehicle, said air flow source being configured to cool the first electric motor and the second electric motor.
