Dental rack and steering gear of the rack/rack type having the rack rack for a vehicle

摘要

Gear racks (200), comprising:a torso (210),which is shaped like a hollow tube, from which an outer peripheral area is combined with an inner side of a rack (137) and an inner peripheral area is combined with a rack (140), the torso (210) being at least one graduated section (135),through which the outer peripheral area of the impactor (210) has several external diameters, which are smaller from one end of the page to the other end of the impactor (210). the toothpick staff (140) and the toothpick housing (137) are supported and the stiffness is maintained, at least one first slot (219),which is formed by cutting one side end in an axial direction and includes at least one second slit (221), which is formed by cutting the other side end in the axial direction and is supported by the first slit (219), where at least one first slot (219) and at least one second slot (221) are placed together; andan elastic element (230) having a ring-shaped shape and in close contact with the outer peripheral area of the body of the bucket (210);where the graduated section (135) of the body of the bucket (210) includes:a section (213) with a large diameter joined to and supported by the rack housing (137), a section (215) with a medium diameter, and a section (217) with a small diameter with a small outer peripheral area, which is combined with the elastic element (230); andwhere the impactor (210) has a section (243) with an enlarged diameter in an inner peripheral area of the impactor (210),where an internal diameter of the section (243) with the enlarged diameter from the section (215) with the mean diameter to the section (213) with the large diameter becomes larger in such a way, that the torso (210) is compatible with the toothpick (140) and an increase in the sliding resistance of the toothpick. (140) and the toothbrush (200) is prevented even when bendingis produced as a result of the production or an increase in the service life of the toothpick (140),characterized by:the section (215) has graduated external diameters with the average diameter, which are smaller from the section (213) with the large diameter, and the section (217) has graduated external diameters with the small diameter, which are smaller from the medium diameter.
