20120144941 | SEQUENTIAL GEARBOX - Embodiments of the invention provide a gearbox including a housing, first and second shafts projecting from the housing, and at least one lay shaft contained within the housing. The first and the second shafts may be connected together by means of gearwheels and the at least one lay shaft in a plurality of transmission configurations. The gearbox also includes a control device movable among multiple consecutive working positions that define different transmission configurations. The control device includes a control shaft able to assume multiple successive angular positions. In some cases the control shaft includes multiple radial recesses spaced circumferentially from each other. At least one poppet ball is pushed radially against the control shaft to engage the radial recesses. Co-operation of the poppet ball with each of the recesses defines a stable equilibrium position for the control shaft. | 06-14-2012 |
20120090429 | MECHANICAL TRANSMISSION DEVICE BETWEEN A DRIVE SHAFT AND TWO DRIVEN SHAFTS - A transmission device includes a drive shaft and two driven shafts. The drive shaft is connected to a wheel and first engagement rotors are arranged therebeside so that the wheel is located therebetween and can rotate together with them. The first engagement rotors having an axial hole in which a driven shaft is rotatably arranged, the first engagement rotors are coupled or uncoupled with second engagement rotors coaxially arranged therebeside, by extracting or retracting, respectively, at least one mobile tooth rotatable in a seat of the first engagement rotors, each driven shaft being keyed to a second engagement rotor. Driving rotors are arranged around the driven shafts between the wheel and the first engagement rotors and are provided with a brake, so that relative rotation of the driving rotors with respect to the first engagement rotors causes extension or retraction of the mobile tooth according to the relative rotation direction. | 04-19-2012 |
