Definitions
- the starter disconnects and requires a delayed restart of the engine.
- a pinion of the starter is shifted so that it engages in the teeth of the flywheel.
- the pinion is disengaged and returns to its original position.
- the permanently starter is permanently engaged.
- the sprocket is constantly connected to the starter sprocket allowing faster and smoother engine restart.
- FIG. 7 shows a detail view according to FIG. 6,
- FIG. 9 shows a plan view of a securing ring
- an inventive freewheel system is shown in partial section.
- an inner ring 1 is driven by a crankshaft 1 a only indicated here, while a starter, not shown, for example, via a pinion with a starter ring gear 2 is in communication.
- the starter ring gear 2 is mounted on a roller bearing 4 via a disc-shaped carrier 3 and is thus connected to a motor flange 5 of an internal combustion engine, not shown here in combination.
- the carrier 3 has radially outward an axial projection 3.1 for receiving the starter ring gear 2 and radially inside an axial projection 3.2 for receiving on the rolling bearing 4. Radially inside is arranged on the outer axial projection 3.1 of the carrier 3, a standing with the starter ring gear 2 outer ring 6.
- the mounting plate 7 is shown in a three-dimensional view and in Figure 5 in a detailed view, in which case also engageable with the groove 4.2 of the roller bearing inner ring 4i shoulders 7.2 and provided for receiving the feet 12.1 of the retaining ring 12 Recesses 7.5 of the storage plate 7 are shown.
- FIG. 9 shows the securing ring 12 with the feet 12.1 in a plan view and in FIG. 10 the friction ring 11 with the radial shoulder 11.1 in a three-dimensional representation.
- the wrap spring 10 is mounted on the axial leg 7.1 of the storage plate 7 and radially biased.
- one end of the wrap 10 is provided with teeth 10.1, which are mounted in the grooves 13.2 of the cage 13. This means that the cage 13 can rotate in one direction against the bearing plate 7 with a frictional torque, but in the other direction the cage 13 and the bearing plate 7 are locked.
- This effect can be explained with the Euler-Eytelwein formula, also called the rope friction formula.
- FIG. 11 shows a three-dimensional partial view of a structural unit consisting of rolling bearing 4, carrier 3 and freewheel.
- the position of the freewheel is shown before starting.
- the freewheel in an open state.
- a gap is present, so that no torque between the inner ring 1 and outer ring 6 is transmitted via the clamping body 14.
- the wrap 10 is shown in Figure 12 in a prestressed state.
