design draisine

[cesare_]

Hi, I should design a draisine (hand trolleys by rail), I need a party, I have to go on the road. my main problem is that I do not know the mechanism that turns into rotary motion to convey to the wheels the alternating movement of the rod (biella manovella...no siò). by chance someone knows where I can find some constructive design of this gadget I know how to tell me quite in depth how it works. I should find a fairly simple and economical way, which can be achieved with a drill, a mill and a lathe. I have to start from scratch, and sincerely I still have no great ideas. I would be happy if someone with a little trick could advise me how to build it (base, axes, wheels...). Thank you.

ciao cesare,
proof of guarare qua http://www.interlok.info/draisinene.htmseems a biella crank on an auxiliary wheel called flywheel to which a pinion is mounted. chain connection on the other toothed wheel connected to one of the two shaft axles.http://www.interlok.info/draischem2.jpgHowever, you also need a welding machine, a flexible machine, a carpenter tool. in itself as a railway vehicle is nothing special.

♪ Axes are two trees mounted on bearings. more on one there is mounted a chain gear
# welded iron frame and covered the wooden boards
# Turned iron flywheel with hole for control rod fixing
# pump arm in welded carpentry
# pump arm rod mounted on bearings
# the brake system on the lever or on the fly or directly on a couple of wheels
# wheels recovered somewhere or those of caries

thank you very much for the advice

Please :finger: I haven't found any other material on my books, but now that you have the principle of operation you can enjoy making measurements and a nice model in solidworks. What do you mean? good work and good party:biggrin:
