摘要： A die for forming a Y-form rack portion of a steering rack bar from a blank by forging in which the die has at least three forming elements (44, 47, 48) relatively movable on application of forging pressure to the die to converge on a blank therein, a first of the forming elements (44) having in its cavities the shape of which corresponds to the shapes of the teeth to be formed, second and third forming elements (47, 48) having forming faces to form longitudinal guide faces (4, 5) on the Y-form rack portion on the side thereof opposite the teeth (8). The three forming elements (44, 47, 48) are shaped and arranged to move together to converge on the blank to transform it into the final form in such a manner as to inhibit escape of the material of the blank between the first and second or first and third forming elements up to substantially the last instant of closure of the die. It is preferred to provide a fourth forming element (30) between the second and third forming elements which serves to guide their movement and to control the shape of a surface of the rack portion (14) lying between the longitudinal guide faces (4, 5) and it is further preferred to impart to the second (47) and third (48) forming elements a rolling motion as they converge on the blank. The die is preferably constructed to be used in a single direction impact press. A method of making a steering rack bar having a Y-form rack portion and a cylindrical portion from a blank by forging is provided in which an accurately shaped and substantially cylindrical blank is first produced and the cylindrical portion of the blank is held while the Y-form rack portion is formed in a die of the configuration described above.

摘要： A rack and pinion steering gear of the kind in which a helical pinion engages a rack mounted in bearings, the rack being supported opposite the pinion by a spring loaded half round support journal, the spring acting to hold the pinion in contact with the teeth of the rack which are formed in such a manner as to provide in about the center of the rack a "ramp" in which there are tooth gaps of varying height providing a variation of slack free mesh center distance between the pinion and the rack, the maximum mesh center distance occurring in the mid travel portion of the rack and lesser mesh center distances occurring in positions of travel of the rack either side of the travel position of the present invention being characterized by the fact that the tooth gaps concerned are formed in such a manner as to form a ramp extending across the rack at an angle substantially the same as the angle made by the pinion axis with the rack axis whereby the possibility of an uneven distribution of the load between the teeth of the pinion and the teeth of the rack is reduced.

摘要： A mechanical function generating mechanism for a front and rear wheel steered vehicle is operable to generate a rear steer angle output as a function of front steer angle and vehicle speed inputs. The mechanism has a three dimensional cam with a cam surface and a contacting follower. The cam surface is traversed relative to the follower in a first direction in accordance with the front steer angle input and is traversed relative to the follower in a second direction substantially at right angles to the first direction according to the vehicle speed input. The follower is constrained to move in a third direction, determined by the shape of the cam surface, substantially normal to the first and second directions to generate the rear steer angle output.
