Definitions
- the invention relates to a starting device for internal combustion engines of the type defined in the preamble of claim 1.
- the sleeve integral with the ring gear has a steep thread on which a driver is arranged so as to be screwable.
- the driver is connected via a freewheel to the starter pinion, which is rotatably and displaceably seated on the gear shaft.
- the driver is axially displaceable by an engagement relay, as a result of which the starter pinion can engage in the toothed ring of the internal combustion engine which projects into its displacement path. If the starter pinion is engaged, the drive motor is switched on. This turns over the transmission, the Driver and the freewheel the pinion.
- the starting device according to the invention with the characterizing features of claim 1 has the advantage that the tips of the shocks caused by the internal combustion engine to be broken down are reduced by the elastic connecting element acting as damping, so that the risk of breakage in the parts transmitting the torque of the drive motor is reduced becomes.
- the damping element itself forms part of the torque transmission train.
- the connecting element is designed as a ring which lies in the ring gear and surrounds the gear shaft and which is positively connected in the direction of rotation on the one hand to the ring gear and on the other hand to the gear shaft, the elastic connection of the ring gear and gear shaft can be realized in a simple manner . It is not necessary to extend the starting device compared to a starting device without such a damping element, because the axial tooth length is due to the shock absorption of the elastic ring internal and external gearing between the ring gear and the drive shaft can be made smaller, thereby creating space for the ring width.
- Fig. 2 shows a section along the line II-II in
- the gear starter shown in detail and in longitudinal section in FIG. 1 as an example of a starter device for internal combustion engines has an electric drive motor 10, a countershaft 11 and a starter pinion 12, which can be engaged by means of an engagement relay (not shown here) in a toothed ring 13 of the internal combustion engine, indicated in detail .
- an electric drive motor 10 known from the housing 14
- the rotor 15 and the drive shaft 16 fixedly connected to the rotor 15 can be seen, which is mounted in a bearing 17 in the housing cover 18 and protrudes from the end of the bearing 17.
- the end section of the drive shaft 16 carries an external toothing 19 which meshes with an internal toothing 20 inside a ring gear 21 of the countershaft 11.
- the ring gear 21 is seated on a gear shaft 24 of the countershaft 11 by means of a sleeve 23 which is integrally formed on a radial flange 22.
- the gear shaft 24 is eccentric to the drive shaft 16 arranged and aligned parallel to this and mounted via bearings 25 and 26 in a gear housing 27 flanged to the housing cover 18.
- the starter pinion 12, which is rotatably and longitudinally movable on the gear shaft 24, is geared to a freewheel gear 28.
- the freewheel gear 28 is connected in a rotationally fixed manner to the gear shaft 24 via a spur toothing 29 and can be longitudinally displaced on the gear shaft 24 via a lever 30, which is actuated by the engagement relay, the starter pinion 12 engaging in the ring gear 13 of the internal combustion engine.
- the gear shaft 24 projects with an end-side cone 31 into the interior of the ring gear 21, the radial flange 22 of the ring gear 21 abutting an annular shoulder 32 which is provided on the end face of the cone 31 having the smaller diameter.
- the outer surface of the frustoconical cone 31 is covered with axial teeth 33.
- the largest diameter of the cone 31 is significantly smaller than the inside diameter of the ring gear 21.
- the axial length of the cone 31 is less than half the depth of the ring gear 21.
- the axial length of the end section of the drive shaft 16, which with its external toothing 19 in the internal toothing 20 which extends over the entire depth of the ring gear 21 meshes, approximately only half as large as the depth of the ring gear 21 t so that the
- Drive shaft 16 ends at a short distance in front of the free end face of cone 31 of gear shaft 24.
- an elastic damping ring 34 for example made of rubber, which couples the ring gear 21 to the gear shaft 24 in a rotationally fixed manner.
- the damping ring 34 engages with an external toothing 35 in a positive manner in the internal toothing 20 of the ring gear 21.
- the inner lateral surface of the damping ring 34 corresponds to the cone 31 frustoconical and carries an internal toothing 36 which form-fitting between the axial teeth 33 on the lateral surface of the .
- Cone 31 of the gear shaft 24 protrudes (Fig. 2).
- damping ring 34 Due to the bevel gear-like course of the interlocking teeth of cone 31 and damping ring 34, which abuts the radial flange 22 with one end face and is held by means of a retaining ring 37, the damping ring 34 is secured against axial displacement, so that the rotationally fixed connection between ring gear 21 and gear shaft 24 is reliably maintained.
- the damping ring 34 reduces the peaks of the shocks caused by the internal combustion engine to be turned on, so that a risk of breakage in the drive train 10 transmitting the torque from the drive motor 10 to the starting pinion 12 is largely avoided.
- damping ring 34 can also be injected as an elastic plastic ring.
