Abstract
The invention relates to a transmission device for the motorization of a rolling-chair for example. Said transmission device comprises a hollow shaft 7 provided at each of its ends with a rolling train 8-13 idly pivoted on the hollow shaft 7 and comprising a toothed crowns 21. It comprises two control shafts 14 slidingly mounted within the hollow shaft 7 merging each out of one end of it. Each control shaft 14 is connected to a pinion intended to cooperate with the corresponding toothed crown 21. It comprises a control device 23 of the axial position of said control shaft 14 with respect to the hollow shaft 7.
Claims13
Transmission device for the motorization of transport means, characterized by the fact that it comprises a hollow driving shaft provided at each of its ends with a rolling train idly pivoted on said hollow shaft and comprising a toothed crown;
- by the fact that it comprises two control shafts slidingly mounted into the hollow shaft merging each out of one end of it;
- by the fact that each control shaft is connected to a pinion intended to cooperate with the corresponding toothed crown of a rolling train;
- and by the fact that it comprises a control device of the axial position of said control shaft with respect to the hollow shaft.
Braking device for transport and handling means comprising at least two rolling trains mounted each at the end of a hollow shaft, characterized by the fact that it comprises control rods slidingly mounted into the hollow shaft merging out of it at each of its ends;
- by the fact that the outside ends of these rods are connected each to a braking pad intended to cooperate with one member of the corresponding rolling train;
- by the fact that the ends of the control rods which are near one another comprise each a member crossing the hollow shaft through a corresponding slot;
- by the fact resilient actions tend to displace the control rods the one towards the other;
- and by the fact that a control member rests on the said members to cause the spreading of said control rods and thus the braking.
