The squidgy things at the dase of the shafts allows the shafts to move forwards and backwards as the pony turns, this allows for maximum bend and minimum restriction on a bend/turn (I beleive) Sue Denny has this arrangement. The delayed steering brake does indeed stop the carriage from snaking in slippery conditions i.e coming down a steep wet hill. When the brake is on, the swing of the front running gear becomes 'stiffer'. It will also help when exiting hazards at speed. Hope this helps. | ||

Hi Mike Thanks for that clarification! This Kuehnle carriage appears to have big rubber things at the base of each shaft http://www.kuehnle.de/files/Neukutschen/N09115-Marathon-Conty-1.jpg I assumed they were some sort of damping mechanism for delayed steering. Perhaps they are neither? | ||

To answer your question martin i would imagine you need delayed steering for all three phases and a turntable break would be most useful in the marathon. I would think Boyd asked his groom to make sure the turntable break was on as he knew he would be going fast and the back of the carriage would slide a lot on a surface. So not to risk the back of the carriage swinging out and hitting a cone costing penalties, if the turntable break was on the risk of this happening would be reduced. This may not be correct but its just how i imagine it works. | ||

I understood it that delayed steering is designed so that the back wheels follow the line of the front wheels therefore not cutting corners, which means your back wheels will not cut in and possible hit a cone or post. Also think turntable breaks are designed to stop the back of the carriage from snaking when coming out of a turn quickly. You should only put it on when you are in slippery conditions or if you are coming out of a fast turn and the carriage is sliding and snaking, once you are straight you turn it off otherwise it will make the carriage heavier for the horses to pull. It is probably used more with multiples than with singles. I could be wrong about all the above so if anyone can put me right please do!! | ||

Chris, the delayed steering mechanisms I've seen are rigid with a lever so that the wheels don't turn as far as the pole or shafts, so that the vehicle doesn't 'cut the corner'. So, like you say, but a geometric 'delay' rather than a timing delay. Like these:   | ||

Very roughly, as far as I understand/can guess: Delayed steering turntables use a damper (a soft squishy thing that slows something down, such as those things you get at the top of doors) or similar mechanism so that the pole or shafts can turn without turning the front axle instantly - giving a slight delay and thereby avoiding your wheel hitting a post as the horse swings around a tight turn. A turntable brake uses friction (like any other brake) to take the energy out of the movement. So, for example, you can prevent the carriage from snaking if you hit anything or turn sharply. Is that right? Anyone acutally have a definative answer on this? | ||

Wish someone would answer your question, Martyn, it's something I've wondered about too. Any takers??? | ||

At the carriage fair Boyd asked his groom to ensure the turntable brake was applied before his demonstration run in the team challenge. Ignoring the turntable lock which I can understand for reinbacks in dressage what benefit does the turntable brake give if any over delayed seering? and is there any advantages of having either and in what phase? |
