Abstract: 797,668. Vehicle power steering. DOWTY EQUIPMENT, Ltd. Nov. 1, 1955 [Nov. 3, 1954], No. 31827/54. Class 79(5) [Also in Group XXXIII] In a servo-operated steering mechanism for an aircraft undercarriage of the kind wherein angular correspondence of the steered part with respect to a pilot member is maintained by power control means responsive to the phase difference between the pilot member and a follow-up member, the undercarriage comprises a cylindrical housing A having a retraction pivot B and a rotatable leg member C, supported by bearings D and E, which carries an arm F for a levered wheel suspension H connected to the lower end of a shock absorber I carried by member C. The steering mechanism comprises a crank pin L secured to member C on an axis offset from the axis of housing A, the crank pin being connected to the piston rod O of an hydraulic steering jack M mounted in trunnions N on the housing A and connected by pipes P and Q to a control valve R. The follow-up and control mechanism, shown at S in Fig. 1, is connected to a steering shaft V mounted rotatably and concentrically within housing A and formed with a slotted head W adapted to engage and disengage the steering means in the aircraft upon lowering and raising of the undercarriage. The mechanism S also carries a follow-up shaft Y connected by an arm U to the crank pin L and reciprocating plungers 26 which operate rockers 27 to actuate valve R. As shown in Figs. 1 (Prov.) and 2, the upper end of the shaft Y carries a disc 1 formed with a pivot pin 4 for a pair of substantially semi-circular cam members 2, 3 shaped on their inner edges as shown by dotted lines in Fig. 1 (Prov.) and formed with peripheral upstanding flanges having outer faces 5, 6 and inner cam faces 7, 8 terminating in bevelled face portions 9, 10. A disc 13 formed on the lower end of a shaft 14, connected to shaft V is formed with a nose 15 which, when shafts V and Y are in phase, rests between the faces 9 and 10. Steering movement of shafts V and 14 will rock one or the other of members 2 or 3 about pivot 4, so that the appropriate face 5 or 6 will cause a rocker 19 or 20 to pivot about a pivot 18 to operate a plunger 21 or 22 forming part of the plungers 26 shown in Fig. 1. The valve R will thereby be operated to energize motor M to steer the member C. Such steering will rotate arm U, shaft Y and disc 1 so that cam members 2 and 3 will be brought to the position in which both faces 9 and 10 cooperate with the nose 15 and the valve R is moved to a neutral position with the undercarriage steered to its selected position. To enable the undercarriage to castor freely the hydraulic steering circuit is placed open to low pressure.
