摘要： A rack-and-pinion steering apparatus in which a steering gear box for transmitting an operation of a steering wheel to road wheels includes a pinion operatively connected to the steering wheel, a rack bar which has a rack meshing with the pinion, and which is operatively connected to the road wheels, a housing slidably supporting the rack bar, a cylindrical rack guide slidably fitted into a guide hole formed in the housing, and a spring member causing the rack guide to abut on a rear part of the rack bar opposite to the rack by biasing the rack guide. A reaction force, which the rack guide receives from the rack bar, acts on the rack guide in such a way as to cause a rotational moment of the rack guide about an axis different from an axis of the rack guide.

摘要： Worm gear mechanism is provided which includes a worm, a torque-transmitting worm wheel and an auxiliary worm wheel. In order to secure a sufficient face width of the torque-transmitting worm wheel, a pitch diameter of the auxiliary worm wheel is set to be greater than a pitch diameter of the torque-transmitting worm wheel. Thus, undesired backlash can be eliminated by the auxiliary worm wheel meshing with the worm with a different meshing phase from the torque-transmitting worm wheel.

摘要： A magnetostrictive torque sensor includes first and second magnetostrictive films which are provided at a shaft and have different magnetic anisotropies; a first measurement coil and a second measurement coil which face the first magnetostrictive film; and a third measurement coil and a fourth measurement coil which face the second magnetostrictive film. A torque applied to the shaft is measured based on a variation in magnetic characteristics of the first and the second magnetostrictive films; and a failure of the magnetostrictive torque sensor is detected based on a first difference between output values from the first and the second measurement coils and a second difference between output values from the third and the fourth measurement coils. An electric steering system includes the magnetostrictive torque sensor for measuring a steering torque of the system; and an electric motor driven based on the measured magnetostrictive torque for steering the vehicle.
