    摘要: An apparatus for measuring and recording the angular position of the edges of axially extending grooves disposed on an inside cylindrical bore surface or outside cylindrical surface of a workpiece is characterized in that the apparatus includes a shoe, pressed into intimate contact with the surface over a zone of the shoe. The zone incorporates an orifice, extending away from the zone of intimate contact to a plenum chamber, to which fluid is supplied. Relative rotation between the workpiece and the shoe is produced. A measuring device measures the degree of restriction to flow of fluid from the orifice as the edges traverse the orifice during relative rotation. An angular positional measurement device measures relative rotation, such that relative angular positions of the workpiece are recorded at each relative rotational position corresponding to a predetermined degree of restriction of the orifice as successive edges of the grooves traverse the orifice.

    摘要: A machine for grinding the metering edge contours on edges of axially extending grooves of a power steering valve input-shaft by means of a cylindrical grinding wheel, the machine being constructed to hold and rotate the input-shaft and to increase and decrease cyclically the distance between the axis of the input-shaft and the grinding wheel several times during the revolution of the input-shaft to grind metering edge contours to produce symmetrical sets of clockwise and anticlockwise metering edge contours. The input-shaft is centrelessly supported by means of surfaces tangentially contacting the outside diameter of the input-shaft. Two such surfaces are axially displaced on either side of the ends of the grooves in the input-shaft and are arranged one on each side of the grinding wheel on that side of the input shaft adjacent the grinding wheel. Other of the support surfaces are arranged substantially at right angles to the first two support surfaces to constrain the input-shaft against motion in a direction parallel to the first two support surfaces. A pair of pressing members contacts the outside diameter of the input-shaft one each displayed axially on either side of the ends of the grooves and loaded so as to press the input-shaft in a direction generally towards the first two support surfaces.

    摘要: A hydraulic power steering rotary valve of generally conventional construction characterized in that the on-center characteristics of the valve are governed by an arrangement of rolling elements and pairs of notched elements arranged to produce a detent action between the input shaft and the sleeve or driven member. One notched element of each pair is fixed to a carrier which is connected to the sleeve or driven member by a securing device. During assembly, the carrier is free to move under the influence of springs acting on the notched elements and thereby take up a position such that after completion of assembly the notched elements and rolling elements are precisely in the correct position to provide the required detent action.

    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.
