Abstract

717,259. Spring forks for motor-cycles. NORTON MOTORS, Ltd. May 21, 1953 [Feb. 22, 1952; June 3, 1952] Nos. 4690/52 and 13922/52. Class 136(3) [Also in Group XXXII] A forked wheel-suspension system for motorcycles comprises spaced fork tubes 5 to the lower end of each of which a substantially horizontal wheel supporting arm 7 is pivotally connected, each fork tube housing a load bearing spring 48 and a slidably mounted cylinder 13 for fluid abutting the spring and connected to the wheel arm to be reciprocated upon up-and-down movement of the wheel, and a piston 19 fixed with respect to the fork tubes working in the cylinder to damp this wheel movement. The piston 19 is fixed with respect to the fork tube by a hollow piston rod 18 which forms a reservoir 28 for replenishing the cylinder 13 with damping fluid. The piston 19 has valve controlled passages 22 connecting spaces 25, 23 which are respectively above and below the piston. A valve disc 27 controls an opening between the reservoir in the tube 18 and the space 23. Upon reciprocation of the cylinder 13 liquid is circulated from one side of the piston to the other and thence to the reservoir 28. A circumferential groove 29 in the piston rod tube 18 has a control opening 30 into the reservoir. Towards the end of the downward stroke of the cylinder 13 the groove 29 enters a gland bearing 20 which masks the opening 30 and restricts the flow to that permitted by a sloping flat 31. The wheel arm 7 is pivotally connected to a bracket 6 on the fork tube 5 and to the cylinder 13 by a link 10. A brake mounting plate 45 is pivotally mounted in the wheel axle 41 and is pivotally connected to a split clamp 47 around the fork tube 5 by a link 46.
