Abstract

572,966. Wheel mountings for motorcycles &c. BALLAMY, L. M., and SHEEPSHANKS, R. H. July 30, 1943, No. 12429. [Class 136 (iii)] Relates to a wheel mounting for motor-cycles and like vehicles of the kind in which the wheel axle 11 is mounted between a pair of substantially horizontal arms 12, 13 urged downwards relatively to the fork blades 16, 17 by resilient load-supporting means 21, 22 disposed adjacent the upper part of the fork blades and connected with the arms by links 26. According to the invention, the fork blades 16, 17 are constituted by a pair of tubes, the resilient means being disposed within the upper ends of the tubes and the links extending downwards within the tubes. Each resilient means, which may be adjustable by the rider while the vehicle is running, is of the pneumatic or oleopneumatic telescopic type comprising a cylinder 23 attached to the fork structure and a plunger 25 therein urged downwards by compressed gas. According to the Provisional Specification (a) the lower ends of the tubular fork blades have bulb-shaped hollow enlargements formed by separate casings and the horizontal arms extend through slots in the casings covered by dirt-excluding rubber &c. seals ; (b) all the pivotal joints of the horizontal and vertical' members are of the rubber bush torsion type ; and (c) the resilient units may consist of cylinder and plunger tubes containing one or more coiled compression springs and liquid damping may be provided.
