Title: Improvements in or relating to steerable undercarriage legs for aircraft
IPC: B64C25/50
Filed: 1945-02-12
Abstract: 588,339. Aircraft undercarriages. GENERAL AIRCRAFT, Ltd., and WELS, O. Feb. 12, 1945, No. 3488. [Class 4] Steering mechanism for an undercarriage wheel, particularly the nose wheel of a tricycle undercarriage, comprises a piston and cylinder connecting the wheel leg with a pilot-actuated rudder-bar or pedal, and a second piston and cylinder connecting the leg with a fixed part of the air frame, each cylinder containing fluid on either side of its piston and being-associated with a valve controlling flow of fluid between its ends, and the valves being simultaneously operable in opposite senses under the pilot's control. In one form, shown diagrammatically in Fig. 1, the leg 3 carries arms 2 and 10 connected respectively to a piston 1, contained in a cylinder 4, connected to a rudder-bar 6, and a piston 11 contained in a cylinder 12, connected to the airframe, piston 11 being urged to a dead centre position by a spring 20. Passages 8 and 13 connecting the ends of the cylinders 4 and 12 are controlled respectively by a rotary valve 9 and a spring-loaded valve 14. The valves are operated by levers 15 and 16, connected by a link 17 and bell-crank lever 18 to a pilot's control 19, the arrangement being such that opening of valve 9 causes closure of valve 14 and vice versa. In operation, with valve 9 open and valve 14 closed, movement of the rudder bar 6 will not affect the wheel, which is held in a central position by the piston 11 and cylinder 12, the latter also serving to damp oscillatory movements of the wheel during landing or take-off. If the wheel was not in a central position when the valve 14 was closed by the control 19, the valve 14 may open under the action of fluid pressure on its underside to allow the piston 12 to return to the deadcentre position and centralize the wheel. For this purpose the operating mechanism of valve 14 may include a cam or similar member. If the control 19 is operated to open valve 14 and close valve 9, movement of the rudder bar 6 will cause movement of piston 1 to steer the wheel, which is now free to move. -In a modification, Fig. 2, cylinders 4 arid 12 are carried by the leg 3, and pistons 1 and 11 are connected respectively to the rudder bar 6 and a fixed part of the air frame. Both valves 9 and 14 are of the rotary type and may be formed integrally and provided with seatings in a casting carried by the leg, Fig. 3 (not shown).

At a limiting speed, the friction blocks leave the boss c centrifugally so that the drive is not transmitted from the pulley to the armature. The pulley flange is preferably extended and flanged over, as shown, to support a casing k around the clutch parts. According to the Provisional Specification, the yoke may be made of two similar pressings each with a central half circular part and a straight arm terminating in a double cranked part, the two being bolted together so as to clamp the shaft. Also, the friction boss may have an internal annular recess closed by a leather or like washer to form an oil chamber.
