| HS{Lord Ernest Hives - Chair}/RM.{William Robotham - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} E1/M24.10.28. ORIGINAL CHRYSLER SPRING DRIVE. 4012. Thank you for your memo. HS{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}8/LG171028. I return herewith description of the above, as requested. We always think that the torque reactions come from the inertia of the flywheel, but this still leaves us with no explanation as to why there is no pronounced torque reaction on the Chrysler. We do know that they have some sort of rubber mounting between the engine and the chassis frame. In our own case however the rubber mounting has not been a cure for this fault. Years ago we fitted a damped spring coupling between the engine and the gearbox for the purpose, I believe, at the time of eliminating a periodic vibration between the countershaft brake drum and engine flywheel. Possibly somebody still at the Works might remember if this had any effect on torque vibrations. E.{Mr Elliott - Chief Engineer} | ||
