Abstract
The steering power transmitting equipment of the present invention comprises a steering gear mechanism having a steering wheel, an upper steering shaft, lower steering shaft and steering gear box, the steering gear mechanism having a torque sensor fixed on the upper steering shaft, a bracket disconnectably fixed to the steering gear box, an electric motor supported on the bracket, a driven gear which is driven by the electric motor and fixed coaxially to the lower steering shaft and an electric controller. The electric controller controls the rotating speed and rotating direction of the electric motor corresponding to the torque and the torque direction inputted by the torque sensor. The power steering gear mechanism is easily mounted on or demounted from standard manual steering equipment without requiring any large scale remodelling of the steering equipment.
