| VIII CRANKSHAFT DAMPERS. As far as I know 90% of the American Cars are using Rubber Crankshaft dampers. There was no trace of the half speed period on the Terraplane 6. Its damper differs from some of the others in that the Rubber is not vulcanised, it is merely squashed into the flywheel under pressure. They say it quickly vulcanises itself. Both Ricards & Essex are emphatic that they were always in trouble with the Lanchester damper and are nearly free from it with the Rubber type. HUDSON TYPE INDEPENDANT SUSPENSION. SPLIT AXLE TYPE There has been no attempt to use very soft front springs with this axle, in fact the ride was not much better than with the conventional type (which as we know from experience is bad). On the other hand, comparing the two cars, the split-axle definately seemed to hold the road far better than the conventional type and killed the axle dither on wavy roads. | ||
