Claim 1
Independent Claim
219 words
In a road vehicle, provided with a running gear in the form of a wheel suspension system with one of the wheels being a steering wheel mounted for horizontal turning about a turning axis by a pitman arm connected thereto, and having a steering system which includes a rod assembly connected for moving the pitman arm, the improvement comprising: a steering gear stabilizer apparatus for resisting turning movement of the steering wheel about the turning axis; said stabilizer apparatus comprising a single fixed mounting bracket, a shaft having opposed ends, compression springs, a universal joint, spring retainers, and a movable mounting bracket; means by which said shaft is reciprocatingly received in supported relationship respective to said fixed mounting bracket; said springs being spaced from one another by said fixed mounting bracket; said spring retainers being affixed to opposed ends of said shaft in a position to bias each of said springs towards said fixed mounting bracket; said universal joint connecting one end of said shaft to said movable bracket; means by which said movable mounting bracket is affixed to said steering system; means by which said fixed mounting bracket is connected in fixed relationship with respect to said movable bracket; so that turning movement of the wheel about the turning axis is resisted by one of said compression springs.
