Abstract:
1. A torque transmission control mechanism for an engine starter inertia drive, the inertia drive including a head, a screw shaft having a pinion thereon, a meshing spring to supply a first spring force to absorb axial shock loads, comprising: a clutch plate stack accommodated on the head and contained within a clutch body such that the first spring force of the meshing spring acts on the clutch plate in a first direction, the clutch body drivably coupled to the screw shaft; and a pressure spring accommodated on the head and providing a second spring force on the clutch plate stack to control a value of torque that may be transmitted through the clutch plate stack without slippage thereof, the second spring force being directed in a second direction in opposition to the first spring force supplied by the meshing spring on the clutch plate stack.
