A New Six-wheeler Conversion ACCOMPANYING illustrations reveal an ingenious suspension arrangement which has been incorporated by Messrs. Masons' Morlode Products, 71, Lewisham High Road, London, S.E.14, in their latest form of six-wheeler conversion of Bedford 2tonners. In slightly modified forms it is suitable for the Fordson and other
well-known makes of 2-ton chassis.
Two inverted semi-elliptic springs are employed on each side, the upper spring being bolted down to an anchorage member which, with a bush of ample dimensions, pivots about a crossshaft ; the extremities of the spring are connected to the upper extensions of the axle brackets.
The extremities of the lower semielliptic spring are correspondingly connected to downward extensions of the axle brackets, but the centre of this spring isnot rigidly fixed to the pivoting anchorage member. Instead, it is arranged to roll slightly fore and aft, bearing against a bushed roller carried on the lower part of the anchorage member.
In the case of the Bedford, radius rods, attached by means of Silentbloc bushes to frame brackets in front of the driving axle, have their rearward extremities attached (also with Silentbloc bushes) to the axle hangers at the level of the lower spring eyes.
The object of this arrangement is that, whilst the deflection of the upper spring on each side controls the arc through which the upper mounting of the axle bracket must move, tbe radius rod controls the are through which the lower mounting must move, the roller device allowing for the slight relative movement in so far as it affects the longitudinal positiOn of the lower
sprit will I ill be recalled that the Bedford
2-tonner has its propeller shaft within a torque tube, which, however, does not take the thrust.
It is pointed out that, by the use of cable-operated brakes and the normal Bedford 16-in, brake drums, a. braking layout is obtained which gives effective action, as well as simplicity of design and a minimum of wearing parts and of weight.
