Abstract

Disclosed is a motor-driven steering system capable of easily adjusting tension. The motor-driven steering system comprises a driven pulley connected to a driving pulley of the motor through a belt, a gear housing for surrounding the driven pulley, a motor housing rotatably connected to the gear housing by means of a hinge shaft, and a guide formed at one side portion of the gear housing. The distance between the driving pulley and the driven pulley is adjusted by rotating the motor housing relative to the gear housing, thereby providing the motor-driven steering system having a simple construction and capable of easily adjusting the tension of the belt.

Description

technical field [0001] The present invention relates to an electric power steering device capable of easily adjusting tension, and more particularly, to an electric power steering device capable of easily adjusting belt tension by adjusting a distance between a driving pulley and a driven pulley. Background technique [0002] As generally known in the art, a steering device of a vehicle enables a driver to freely control the running direction of the vehicle by turning a steering wheel. That is, by changing the direction of the front wheels, the steering allows the vehicle to be steered in whichever direction the driver desires. [0003] In order to turn the wheels in a state where the vehicle has stopped, power is required that is greater than the frictional force between the vehicle and the road surface, and in particular, the frictional force increases when the weight of the vehicle increases and / or when the width of the wheel becomes wider. In order to enable the driver ...
