  • Electrical auxiliary module for a vehicle steering system
    Patent number: 8833508
    Abstract: An auxiliary module has a gearbox, a motor, a torque detector and a controller. The gearbox has a casing, a sun gear, a planet gear assembly, a driven gear and a driving axle. The planet gear assembly engages the sun gear and has a driving gear, multiple planet gears and an annular gear. The planet gears are mounted rotatably on the driving gear and engage the sun gear. The annular gear is mounted around and engages the planet gears. The driven gear engages the driving gear. The driving axle is mounted co-axially on the driving gear. The motor is connected co-axially to the sun gear. The torque detector is mounted on the casing of the gearbox with fasteners to detect torque applied on the driving axle. The controller is connected electrically to the motor and the torque detector to adjust torque output from the motor.
