  • Cox Att0rneyYount, Flynn & Tarolli ABSTRACT A vehicle engine starting system providing solenoid-operated positive engagement of the starting pinion with the ring gear on the engine flywheel before the starting motor is energized and inertia-operated disengagement of the pinion when the engine begins to overrun the starting motor.
  • the system has an electrical lockout which positively prevents reengagement of the pinion as long as the engine ignition switch remains closed.
  • a principal object of the present invention is to provide a novel and improved engine starting system which avoids these disadvantages by combining electrically operated positive engagement of the pinion before the starting motor is energized, inertia-operated disengagement of the pinion once the vehicle engine begins to overrun the starting motor, and positive lockout of the pinion after it has been disengaged.
  • Another object of this invention is to provide such an engine starting system in which the inertia-operated disengagement of the starting motor-driven pinion causes the starting motor and the solenoid to be deenergized automatically.
  • Another object of this invention is to provide an engine starting system having an electrical control circuit with a novel and improved lockout for positively preventing reengagement of the pinion as long as the ignition switch for the vehicle engine remains closed.
  • FIG. 1 illustrates schematically in longitudinal section the mechanical portion of the present starting system
  • FIG. 2 is a schematic electrical circuit diagram of the control circuit in the present engine starting system.
  • the present engine starter comprises a rotary, longitudinally splined, axially-fixed shaft which is driven by the starting motor M in FIG. 2, and a drive pinion 11 which is adapted to be driven from shaft 10 as explained hereinafter.
  • the drive pinion 11 is shiftable axiallyof the shaft 10 into and out of meshing engagement with the usual ring gear 12 on the flywheel of the vehicle engine.
  • the drive pinion 11 is splined to the outside of an annular pinion-carrier 13 which surrounds the starting motor-driven shaft 10.
  • the splined connection of the pinion 11 to the pinion carrier has a slight spiral twist or pitch which causes the pinion to turn on the pinion carrier when one moves axially with respect to the other, in order to facilitate the meshing engagement of the pinion with the ring gear 12.
  • the pinion carrier has a reduced diameter portion 13a on which are mounted an annular thrust plate 14 and a flanged sleeve 15.
  • the sleeve 15 is held in place on the reduced end portion 13a of the pinion carrier by a snap ring 16.
  • the thrust plate 14 is engaged snugly between the inner end of sleeve 15 and an annular, radially disposed shoulder 13b on the pinion carrier.
  • a coil spring 17 is engaged under compression between the thrust plate 14 and the drive pinion l1, urging the pinion to the right along the pinion carrier 13 for engagement with a snap ring 18 carried by the pinion carrier.
  • This spring yields if the pinion is initially brought into abutting engagement with the ring gear 12 and then, after the pinion has turned on the pinion carrier enough to clear this abutting engagement, the spring forces the pinion into meshing engagement with the ring gear.
  • the sleeve 15 is connected through a suitable linkage, designated schematically by the dashed line 19, to the reciprocating armature 20 of a solenoid 21- provided with a conventional return spring (not shown) which normally maintains the armature 21 in an extended position (to the right in FIG. 1).
  • the arrangement is such that, when the solenoid 21 is deenergized and its armature 20 is in its extended position, the unitary assembly of sleeve 15, plate 14, pinion carrier 13 and pinion 11 is retracted to the left along shaft 10 from the position shown in FIG. 1 to a position in which the flanged left end of sleeve 15 abuts against a brake washer 29 located in front of a wall portion 28a of the stationary housing for this mechanism.
  • a drive sleeve 22 is engaged between the shaft 10 and the pinion carrier 13.
  • This drive sleeve is splined to the shaft 10 for movement axially along the shaft and is in screw-threaded engagement with the pinion carrier by virtue of external Acme threads 23 on the drive sleeve engaging complementary internal screw threads 24 on the pinion carrier.
  • the pinion carrier presents a radially disposed, annular internal shoulder 25 which limits the movement of the drive sleeve 22 to the left. with respect to the pinion carrier.
  • This disengagement sleeve has its right end abutting against a flanged bushing 27 mounted in another wall portion 28b of the housing.
  • the electrical control circuit in the present-starting system includes a normally open ignition switch30 connected in series with the vehicle load and engine ignition circuit 31 across a direct current power source, such as the vehicle battery 32.
  • the starting motor M is connected in series with a set of normally open solenoid contacts 33 across the power source 32. Contacts 33 are closed when the armature is pulled in by the solenoid 21, when the solenoid is energized and at a time when the meshing engagement of the pinion 11 with the ring gear 12 is assured.
  • a first coil 37 for opening the contacts 36, 35 is connected in series with a semiconductor rectifier 38 between the ignition switch and the solenoid contacts 33. When energized, coil 37 moves the mobile contact 36 away from the fixed contact 35 and into engagement with a fixed contact 39 connected to the juncture 40 between coil 37 and the anode of rectifier 38.
  • a second coil 41 is connected in parallel with the starting motor M and when energized it closes a set of normally open contacts 42, 43.
  • the fixed contact 43of this set is connected to the starting switch 34, and the mobile contact 42 is conthe same time, as described with reference to FIG. 1, the energization of solenoid 21 causes the pinion 11 to be moved into meshing engagement with the ring gear 12.
  • the closing of the solenoid contacts 33 completes the energization circuit for coil 41, which closes its contacts 42, 43 to provide a holding circuit for maintaining solenoid 21 energized independent of contacts 35 and 36.
  • the continued energization of the solenoid depends upon the drivers holding the starting switch 34 closed.
  • the opening of the solenoid contacts .33 breaks the energization circuit for the starting motor M and coil 41.
  • coil 41 When coil 41 is deenergized, its contacts 42, 43 reopen, breaking the holding circuit for solenoid 21,.so that solenoid 21 now is deenergized and cannot be reenergized while coil 37 remains energized, which'condition prevails as long as the ignition switch 30 for the vehicle engine remains closed. Consequently, the driver cannot restart the starting motor M as long as the vehicle engine remains running.
  • the disclosed embodiment of the present engine starting system provides solenoid-operated positive engagement of the starting motor-driven pinion with the ring gear connected to the engine, inertia-operated disengagement of the pinions from the ring gear once the engine begins to overrun the starting motor, and a novel control arrangement which insures that once the pinion is disengaged it cannot be reengaged as long as the engine ignition switch remains closed.
