-rwo new products to be exhibited by A Laycock Engineering, Ltd., at the Commercial Motor Show will be a clutch and a rubber-insulated propeller-shaft coupling..
The new clutch is known as the Laycock-Haussermann unit, and its principal feature is a diaphragm spring to replace the coil springs of a conventional clutch. The main advantages of the circular diaphragm are that only a light pedal pressure is required to release and hold out the clutch and the spring characteristics remain constant during the normal life of the driven plate.
There is a minimum number of working parts, and correct balance is maintained under all running conditions.
At present the clutch is being made in sizes suitable for cars and light commercial vehicles, but larger sizes may be produced in future.
Elimination or reduction of "body boom" is the purpose of the new Laycock T.R. transmission coupling. The inclusion of this coupling in a transmission line eradicates the high-frequency vibrations which cause body boom, whilst other vibrations are also damped and a cushioning effect is given throughout the transmission.
The new coupling consists of two cupshaped members between which there is a compressed rubber ring. This is located approximately centrally over the universal-joint pivot axis sb that it transmits torque only.
The coupling can be used at either end of the propeller shaft, although it has been found more effective when fitted at the axle end.
The cup members carry studs which coincide with the standard drillings of Hardy Spicer universal-joint flanges to simplify incorporation of the new coupling in existing transmission lines.
