Abstract

677,058. Spring forks for motor-cycles. KRONPRINZ AKT.-GES. FUR METALLINDUSTRIE. Feb. 20, 1951 [Feb. 21, 1950], No. 4119/51. Class 136(iii) [Also in Group XXXII] In a vehicle suspension having a column of rubber or similar elastically deformable material disposed in a tube between an abutment and a slidable piston, a compression spring 14, adapted to absorb lighter shocks jointly with the - rubber column 5, is arranged between the piston 10 and the column and in series with the column. and an extension 15 formed on the piston 10 engages the rubber column after the piston has performed part of its stroke, to transmit heavy shocks direct to the rubber column. As shown, a motor-cycle front wheel fork comprises two handle carrying tubes 1 telescopically mounted on lower tubes 2 which carry the wheel axle. A transverse wall 4 near the bottom of each tube 2 acts as an abutment for the rubber column 5 which is guided in the tube 2 by metal rings 6 bedded in the column. The piston 10 is carried by a rod 11 fastened at its upper end to the tube 1. A recoil spring 16 is mounted above the piston 10 and bears against an abutment 17 at the top of the tube 2. The spring 16 also serves to prestress the rubber column 5 and the spring 14.
