摘要:
A drive transfer device comprising: a first rotating element (6) having a plurality of apertures (38) therein; a second rotating element (4) adjacent the first rotating element (6); a plurality of transfer elements (10); and a control element (12) mounted for rotation with the first element (6) and moveable with respect to the first element (6) between a first position in which the control element (12) holds the transfer elements in an engaged position where the transfer elements (10) extend through the apertures of the first rotating element to engage with the second rotating element (4) to urge them to rotate together, and a second position where the transfer elements are moved and held out of engagement with the second rotating element.
摘要:
It comprises a mechanical power input (1, 55) receiving the power preferably from an electric motor and a mechanical power output (3, 67), as well as transfer means (2, 2', 2'', 2''', 4, 64) for transferring this power from the input to the output, and control means (2, 5, 6, 7, 59, 60, 61) for controlling the transfer means (2, 4, 64) to make sure that the power transferred at the output does not exceed a predetermined level. There are provided means to break down the power received at the input into a power applied at the output (3, 67) and excess power which is used to produce the cut-off of power supplied by the motor. This excess power is controlled by the pressure of element (6, 7, 61) whose tension is adjustable which actuates against a movable surface which defines a cam profile, thereby increasing the force or torque during the angular or linear motion of the cam (2, 2', 2'', 2'''). The transfer mechanism includes a basic group with four different output alternatives (C1, C2, C3 and C4).
摘要:
A device for the shaft-hub coupling, in particular for the automotive sector. The peculiarity of this device is that it comprises a box-like body (4) arranged to be inserted inside a shaft (2), to be coupled with a hub (3). The body (4) further has removable means (5, 5', 5"), operable by means of a lock (6), for engagement with the hub (3).
