Abstract: 1,053,446. Speedometer transmission mechanism. FORD MOTOR CO. Ltd. May 15, 1965, No. 20626/65. Headings G1K and G1N. A "fifth wheel" towed by a vehicle incorporates a tachogenerator whose output frequency is determined by the speed of the vehicle. The invention is concerned with the mechanical means for reducing the bounce of the wheel over a rough surface. The wheel, carried by a first arm 9 attached by a coupling 12 to the rear of the vehicle, comprises a tyre 4 on a rim 1 bolted to a web 2 and hub 5 mounted by bearings 8 on an axle 7 attached to the arm 9. A second arm 17 is attached to the first arm 9 through a rubber bushing acting as a spring connection between the two arms. The free end of arm 17 carries a weight 21 with an oval hole 22 allowing limited movement between the two arms, further limited by stops 23 on the weight 21, and buffers 24 on the arm 9. The tachogenerator comprises a toothed wheel 24 attached to the web 2, the teeth passing close to a transducer 28 producing pulses whose frequency is measured, to determine the speed, and integrated, to determine the distance travelled.
