A design of power-assisted device on steering wheel

In motor tricycle,this operation that turning the steering wheel by the steering body is usually very laborious for the driver.There are many existing power steering device for motor vehicles,including electronic,hydraulic power unit.but the price are high and not suitable to used in motor tricycle.This paper mainly studies on the issue of the power assisting device on steering wheel.After analyzing the existing power assisting device on steering wheel,we design a new one in order to make the motor vehicle steering more easily than before.The key to the point is that the device can strength the power exerted in the steering shaft of front wheel through the meshing of two gears,which can make steering more effective.The power in the front wheel steering shaft is magnified about 14 times.The manufacturing cost of this device is lower and it can be used in other occasions to enlarge the power.
