Steering device for buses

Claim 1

An improved steering mechanism for buses, comprising: front running wheels; steering pivot pins mounted on the front wheel axle of the vehicle; a vehicle steering wheel and steering movement transmission means arranged to effect turning of said running wheels jointly about their respective pivot pin; a vehicle chassis frame; a second frame supporting said wheel axle and being located below the vehicle chassis frame and attached thereto, at its front end, through a moment-free connection and at its rear end through a spring-suspended connection positioned behind said front running wheels; an essentially vertical steering link shaft arranged for turning upon rotation of the vehicle steering wheel and positioned close to the vehicle longitudinal axis, said vertical steering link shaft being mounted on and within said second frame at a point between said moment-free and spring-suspended connections so as to partake in the wheel axle movements; said steering movement transmission means being mounted on said vehicle chassis frame and being positioned approximately in the same vertical plane extending at right angles to the vehicle longitudinal axis as said moment-free connection of said second frame to said vehicle frame; steering movement coupling means coupling said steering movement transmission means to said vertical steering link shaft; and linkage means including obliquely outwardly directed steering links coupling said vertical steering link shaft to said front running wheels, whereby upon steering movements of said steering wheel said front running wheels may be deflected through a wide angle.
