The invention relates to an automatic clearance adjusting device of an automobile steering device. The automatic clearance adjusting device comprises a shell and a rack of which the back surface is a cylindrical surface, wherein the cylindrical surface is matched with a supporting yoke; an adjusting block is arranged on the rear side of the supporting yoke; the supporting yoke is connected with the adjusting block in a rotational mode; a threaded guide groove is formed inside the shell and is matched with a threaded guide block arranged at the periphery of the adjusting block; an adjusting nut is arranged on the rear end part of the shell; and a pre-compression spring is arranged between the adjusting nut and the adjusting block. The automatic clearance adjusting device has the characteristics of capability of adjusting the clearance between a gear and the rack in time, low noise, uniform acting force between the adjusted gear and rack and capability of well ensuring the service life of the gear and the rack.
Description
technical field [0001] The invention relates to an automobile steering gear, in particular to a gap adjustment device for an automobile steering gear. Background technique [0002] Steering gear can be divided into various types according to the structure. There have been many forms of steering gears in history. At present, the more commonly used ones are rack and pinion type, worm crank finger type, recirculating ball-rack and pinion fan type, recirculating ball crank finger type, worm roller type and so on. The rack and pinion type is the most common steering gear. Its basic structure is a pair of intermeshing pinion and rack. When the steering shaft drives the pinion to rotate, the rack will move in a straight line. Sometimes, the steering wheel can be turned by directly driving the tie rod by the rack. Therefore, this is the simplest steering gear. It has the advantages of simple structure, low cost, sensitive steering, small size, and can directly drive the tie rod...
