Drive device for control and / or in addition to aggregates transmission drives a piston internal combustion engine and piston internal combustion engine with such a drive device

摘要

The drive device is provided with a drive wheel (16) and a in operative connection with a control assembly and / or in addition to units, which can drive the piston internal combustion engine driven gear (24). Furthermore, the drive device is provided with a round the drive wheel (16) and the drive wheel (24) is guided in a circulating traction means (18), which is a load end (78) and a return strand (54) forms. The drive device has a on the return strand (54) of the traction means (18) which is applied to the tensioning means (44) on. The drive device is provided with a motion conversion unit (46) for converting a displacement of the drive wheel (16) relative to the driven gear (24) into a movement of the additional biasing means (44) in the direction of the traction means (18) or away from the same. The clamping means (44) has a sliding shoe (48) having a lower surface (52) with a sliding surface for bearing on the traction means (18) as well as with an upper side (56) and a pressing element (58) for the pressing force acting on the slide shoe (48), wherein the sliding shoe (48) on its upper side (56), both an articulation point (70) for the articulated connection with the movement of the reaction of a unit (46) as well as a press-on zone (62) for by the pressure element (58) of pressure occurring force action on the slide shoe (48) comprises.
