Title: Telescopic, shock,absorbing aircraft undercarriage strut - has hinge pins of steering linkage non-perpendicular to strut axis of movement to cause toe-in of wheels
Inventor: ARENDTS FRANZ-JOSEPH DIPL ING
IPC: B64C25/02
Filed: 1978-04-08
Abstract: The telescopic, shock-absorbing aircraft undercarriage strut comprises the usual piston (12) and cylinder (11) assembly with an external steering and damping scissors-linkage (14). The three linkage hinge pins (15a, 15b, 15c) instead of being truly perpendicular to the axis of movement of the strut (17) are at an angle (alpha) to the Y-axes of the hinges, which are congruent with that axis. The pins are carried in self-aligning roller bearings. Toe-in is thus kinematically linked with struct compression, the pin angle being chosen to give nil toe-in on starting.
