Definitions

  • the present invention relates to starters and, more particularly, to a starter having a main electromagnetic switch, operative to open or close a main contact of a motor circuit, and an auxiliary electromagnetic switch short circuiting energization limiting means provided in a motor circuit.
  • the starter device has an auxiliary electromagnetic switch, operative to supply or shut off electric current being supplied to the main electromagnetic switch, which is mounted on at least one of a plurality of mounting seats provided on a housing.
  • the housing has a flange member through which the starter is mounted on an engine.
  • the flange member is formed with a plurality of engine mounting bores to allow the starter to be mounted on the engine and a plurality of housing mounting bores to be mounted on the housing.
  • the housing has a plurality of flange mounting bores for mounting the flange member. This allows the flange mounting bores and the housing mounting bores to be selected in combination to enable the housing to be mounted on the flange member at a variable mounting angle.
  • auxiliary electromagnetic switch With such a structure, of the plural switching mounting seats provided on the housing, selecting either one of the mounting seats enables the auxiliary electromagnetic switch to be mounted on a common housing at variable mounting positions. This makes it possible to avoid the auxiliary electromagnetic switch from interfering with an engine block and equipment installed on the engine at a periphery thereof.
  • selecting the mounting angle of the housing with respect to the flange member enables the mounting angle of an entire structure with respect to the engine to be altered. Therefore, altering the combination between the mounting angle of the housing and the mounting angle of the auxiliary electromagnetic switch results in a further increase in a freedom of mounting the auxiliary electromagnetic switch.
  • the housing has the plurality of switch mounting seats, which are substantially limited to three areas covering an upper area and left and right side areas of the housing with a less effect of avoiding the interference with the engine block and equipment installed on the engine at the periphery thereof.
  • Patent Publication 1 describes that it is possible to adjust the mounting angle even if the housing and the flange member and the switch mounting seats are altered in combination with the adjustment of the mounting angle enables the auxiliary electromagnetic switch to be mounted with increased freedom.
  • the related art takes the form of a structure in which the housing and the flange member are separate from each other with an increased limitation in available physical space.
  • the related art can be implemented in a large-sized starter but a difficulty is encountered for the related art to be implemented in a small-sized starter.
  • the starter has an extremely limited installation space.
  • the switch mounting seat except for the switch mounting seat on which the auxiliary electromagnetic switch is actually mounted, protrudes in a direction different from an orientation in which the auxiliary electromagnetic switch is mounted. This results in a difficulty of avoiding the interference with the engine block and equipment installed on the engine at the periphery thereof.
  • a switch current has an extremely large value of 100A or more.
  • the auxiliary electromagnetic switch is provided in general to protect a starter relay which has a small contact capacity
  • the auxiliary electromagnetic switches have increasing applications even to the small-sized starters with a purpose different from that of the large-sized starter because of a reason described below.
  • a method has been conceived in which a parallel circuit composed of a resistor element and an auxiliary electromagnetic switch, connected in parallel to each other, is connected to the motor circuit of the starter to allow the resistor element to supply limited current to a starter motor for energization thereof during the startup of the starter after which the auxiliary electromagnetic switch is closed in operation to apply the starter motor with the full voltage of the battery.
  • a parallel circuit composed of a resistor element and an auxiliary electromagnetic switch, connected in parallel to each other, is connected to the motor circuit of the starter to allow the resistor element to supply limited current to a starter motor for energization thereof during the startup of the starter after which the auxiliary electromagnetic switch is closed in operation to apply the starter motor with the full voltage of the battery.
  • JP 07-109967 has been interpreted by the European Patent Office as disclosing a starter for starting up an engine having a ring gear, the starter having a housing adapted to be mounted on the engine, a motor fixedly mounted on the housing to generate a rotational force, a pinion gear operative to transfer the rotational force from the motor to the ring gear, a motor circuit having a main contact to apply electric power from a battery to the motor, a main electromagnetic switch operative to open or close the main contact and operative to actuate the pinion gear toward the ring gear, energizing current limiting means connected to the motor circuit at a high voltage potential side for limiting an electric current flowing through the motor, and an auxiliary electromagnetic switch having an auxiliary switch composed of a pair of stationary contacts, connected between low and high voltage potential sides of the energizing current limiting means, and a movable contact operative to connect or disconnect the pair of stationary contacts to short circuit the energizing current limiting means when the pair of stationary contacts are conducted with the
  • the present invention has been completed with a view to addressing the above issues and has an object to provide a starter that can be easily manufactured on a mass production basis with a technology of permitting an auxiliary electromagnetic switch to be mounted at finely variable mounting angles.
  • the present invention provides a starter in accordance with independent claim 1. Preferred embodiments of the invention are reflected in the dependent claims.
  • the present disclosure provides a starter for starting up an engine having a ring gear, the starter having a housing adapted to be mounted on the engine, a motor fixedly mounted on the housing to generate a rotational force, a pinion gear operative to transfer the rotational force from the motor to the ring gear, a motor circuit having a main contact to apply electric power from a battery to the motor, a main electromagnetic switch operative to open or close the main contact and operative to actuate the pinion gear toward the ring gear, energizing current limiting means connected to the motor circuit at a high voltage potential side for limiting an electric current flowing through the motor, and an auxiliary electromagnetic switch having an auxiliary switch composed of a pair of stationary contacts, connected between low and high voltage potential sides of the energizing current limiting means, and a movable contact operative to connect or disconnect the pair of stationary contacts to short circuit the energizing current limiting means when the pair of stationary contacts are in contact with the movable contact.
  • the main electromagnetic switch is turned on, the main contact is closed to cause the energizing current limiting means to limit the electric current flowing through the motor after which the auxiliary electromagnetic switch is energized at a given timing to short circuit the energizing current limiting means to allow a full voltage to be applied from the battery to the motor.
  • the main electromagnetic switch is fixedly mounted on the housing by means of a plurality of bolts in a first area close proximity to an outer circumferential periphery of the motor.
  • the auxiliary electromagnetic switch is fixedly mounted on at least one of the housing or an end frame of the motor via a mounting member in a second area in close proximity to the outer circumferential periphery of the motor.
  • the mounting member may preferably include a bracket with which the auxiliary electromagnetic switch is fixedly mounted on the housing.
  • the bracket includes a first terminal member, to which the auxiliary electromagnetic switch is fixedly secured, and a second terminal member, interleaved between the housing and the main electromagnetic switch, which is fixedly attached to the housing by means of at least the plurality of bolts for fixing the main electromagnetic switch, wherein the second terminal member has bores through which the bolts are inserted and whose positions are altered to enable a circumferential angular mounting position of the auxiliary electromagnetic switch to be altered with respect to an axis of the main electromagnetic switch.
  • the bracket can be formed with bores at varying positions. This allows the auxiliary electromagnetic switch to be mounted at mounting positional angles that can be finely altered with respect to an axis of the main electromagnetic switch. Further, no need arises to provide the plurality of switch mounting seats as required in the related art (Patent Publication 1).
  • the starter has no protruding portion protruding from a contour of the starter in an area except for an orientation in which the auxiliary electromagnetic switch is mounted. As a result, this prevents the auxiliary electromagnetic switch from conflicting with the engine block and equipment installed on the engine at the periphery thereof, thereby providing increased mounting capability.
  • auxiliary electromagnetic switch is fixedly secured to the housing via the bracket, the teaching of the present disclosure can be applied not only to the large-sized starter but also to the small-sized starter.
  • the starter can have increased vibration resistance without increasing coupling torques of the bolts to a degree more than necessary.
  • the auxiliary electromagnetic switch may be preferably fixedly mounted on the end frame of the motor via the mounting member such that at least a part of the auxiliary electromagnetic switch axially falls in an area to which the main electromagnetic switch is projected in an axial direction.
  • the starter can have a further minimized projection area in the axial direction than that achieved in a case where both of the main electromagnetic switch and the auxiliary electromagnetic switch are arranged in parallel to each other.
  • no remarkable increase occurs in an installation space of the engine as compared to a starter in which no auxiliary electromagnetic switch is provided. This enables the engine to have an installation space without causing the auxiliary electromagnetic switch from conflicting the engine block and equipment installed on the engine at the periphery thereof.
  • the auxiliary electromagnetic switch may preferably include the energizing current limiting means.
  • the main electromagnetic switch may preferably have one axial end fixedly secured to the housing and the other axial end carrying thereon two terminal bolts through which the main electromagnetic switch is electrically connected to the motor circuit.
  • the auxiliary electromagnetic switch has one axial end fixed to the bracket and the other axial end carrying thereon two terminal bolts through which the auxiliary electromagnetic switch is electrically connected to the motor circuit.
  • a conductive metallic plate member provides an electrical and mechanical connection between a terminal bolt, forming one of the two bolts of the main electromagnetic switch and placed at a high voltage potential side, and a terminal bolt forming one of the two bolts of the auxiliary electromagnetic switch and placed at a low voltage potential side.
  • the auxiliary electromagnetic switch can be supported with the bracket and the metallic plate-like member on a center impeller. This allows the auxiliary electromagnetic switch to have remarkably increased vibration proof qualities, while enabling a reduction in wall thickness of the bracket and minimizing an increase in weight of the starter.
  • the bracket may preferably have a first terminal member, on which the auxiliary electromagnetic switch is fixedly secured, a second terminal member, dislocated from the one end portion in an axial direction, which is interleaved between the housing and the main electromagnetic switch, and a connecting portion, interconnecting the first and second terminal members to each other along the axial direction, which is curved in a circular arc configuration along an outer circumferential periphery of the main electromagnetic switch.
  • the connecting portion of the bracket has further increased rigidity than that of a bracket having a connecting portion formed in a flat shape, enabling an increase in vibration resistance.
  • the auxiliary electromagnetic switch may be preferably placed in the area to which a whole of the main electromagnetic switch is projected in an axial direction.
  • the main electromagnetic switch and the auxiliary electromagnetic switch may preferably have axes placed in a coaxial relationship.
  • At least a part of or a whole of the auxiliary electromagnetic switch can be structured to fall in the area to which the main electromagnetic switch is projected.
  • the main electromagnetic switch and the auxiliary electromagnetic switch may preferably have axes that intersect at a right angle.
  • the main electromagnetic switch has not only a function to open or close the main contact of the motor circuit but also a function to drive a shift lever to push the pinion gear toward the ring gear of the engine.
  • the auxiliary electromagnetic switch has only a switching function to short circuit the current limiting means connected to the motor circuit. This enables the auxiliary electromagnetic switch to have a shorter overall length (axial length) than that of the main electromagnetic switch. Therefore, even if the auxiliary electromagnetic switch and the main electromagnetic switch are placed in an arrangement to have axes intersecting with each other at a right angle, no risk occurs for the auxiliary electromagnetic switch to remarkably protrude from the area to which the main electromagnetic switch is projected in the axial direction.
  • the main electromagnetic switch may preferably have a terminal kept at a high voltage potential to which a terminal of the auxiliary electromagnetic switch remaining at a low voltage potential is electrically and mechanically connected via a metallic connecting member.
  • connection terminals of the main electromagnetic switch and the auxiliary electromagnetic switch have connection terminals connected to each other via, for instance, a wire
  • connection terminals of the main electromagnetic switch and the auxiliary electromagnetic switch are connected to each other by means of the metallic connecting plate, thereby providing an increase in vibration proof.

  • the auxiliary electromagnetic switch is inserted to an inner periphery of the band portion with the leg portion, formed on the both ends of the band portion being fixedly secured to the end frame with the screws, the auxiliary electromagnetic switch can be fixed to the end frame.
  • the auxiliary electromagnetic switch can be easily fixed to the end frame via the mounting member without causing a need to have a flange portion through which screws or bolts are inserted.
  • the mounting member is made of metallic plate material that is folded.
  • the metallic plate material is bent in an annular configuration to allow the band portion to have the both ends formed with the leg portions, thereby providing an ease of fabricating the mounting member.
  • the metallic plate material takes the form of a simple configuration (such as, for instance, a band-like rectangle shape), thereby enabling an increase in yield when manufacturing a mounting member from a metallic raw material with a resultant reduction in production cost.

  • the starter 1 can have additional specified coupling means (such as, for instance, bolts) for fixing the bracket 24 and the bracket 24 can be prevented from being rotated.
  • the starter 1 can have increased vibration resistance and reliability
  • the connecting portion 24d with which the first and second terminal members 24a and 24c are connected to each other, is curved in the circular arc configuration along the outer circumferential wall of the main electromagnetic switch 8. Therefore, the bracket 24 has the connecting portion 24d with further increased bending rigidity than that of the connecting portion formed in a tabular configuration, enabling an increase in vibration resistance.
  • the terminal bolt 29 is electrically and mechanically connected to the B-terminal bolt 15 of the main electromagnetic switch 8 via the metallic plate-like connecting member 31 such that the auxiliary electromagnetic switch 10 is supported on a center impeller with the bracket 24 and the plate-like connecting member 31.
  • the starter 1 can have further remarkably increased vibration resistance than that achieved with a starter in which the auxiliary electromagnetic switch 10 is supported on a cantilever support using only the bracket 24. This also results in a reduction in a plate thickness of the bracket 24, thereby enabling the suppression of an increase in weight of the starter 1.
  • the resistor element 9, connected to the motor circuit is incorporated inside the auxiliary electromagnetic switch 10 and no need arises to prepare a specified member to protect the resistor element 9 from an external environment. In this case, no physical increase occurs, thereby contributing to on-board mounting capability of the starter 1 with respect to the engine.

  • the switch coil 12 is de-energized with the attraction force being distinguished, the plunger 13 is pushed back to its original position by a reactive force of a return spring (not shown) to thereby open the main contact MC.

  • the screws S 1 are screwed into threaded bores (not shown) formed in the mounting seats 40a of the end frame 40 to be tightened to tightly fix the band portion 50a in place.
  • the auxiliary electromagnetic switch 10 is fixedly mounted on the end frame 40 as shown in FIGS. 6 and 7 .
  • the auxiliary electromagnetic switch 10 is fixedly mounted on the end frame 40 by means of the mounting member 30. With such a mounting state, the auxiliary electromagnetic switch 10 is placed such that the movable core 27 axially moves in the same direction (as viewed in a lateral direction in FIG. 6 ) as that in which the plunger 13 of the main electromagnetic switch 8 axially moves and a whole of the auxiliary electromagnetic switch 10 falls in an area to which the main electromagnetic switch 8 is projected in an axial direction. That is, the electromagnetic switches 8 and 10 have axes placed on a coaxial relationship with respect to each other with the auxiliary electromagnetic switch 10 having a diameter determined to be slightly less than that of the main electromagnetic switch 8.
  • the auxiliary electromagnetic switch 10 has two terminal bolts 29 and 30 connected to the stationary contacts 25 and 26 of the auxiliary contact AC.
  • the two terminal bolts 29 and 30 are placed in areas axially close to the two terminal bolts (B-terminal bolt 15 and M-terminal bolt 16) extending through the main electromagnetic switch 8.
  • the two terminal bolts 29 and 30 include the first terminal bolt 29, connected to the positive-electrode side terminal of the battery 11 via the battery cable, and the second terminal bolt 30 electrically and mechanically connected to the B-terminal bolt 15 of the main electromagnetic switch 8 via a metallic connecting plate 34A.

  • the starter relay 22 is turned on such that the switch coil 12 is energized.
  • the plunger 13, shown in FIG. 9 is attracted to move leftward in the drawing figure. This allows the shift lever 7 to be actuated to push the pinion gear 6 toward the ring gear 5 (rightward in the drawing figure).
  • the main contact MC is closed to cause the battery 11 to apply electric power to the resistor element 9 through which the limited electric current is supplied to the motor 4 to rotate the same at a low speed.
  • the pinion gear 6 is brought into meshing engagement with the ring gear 5 and, thereafter, the ECU 23 energizes the excitation coil 32 of the auxiliary electromagnetic switch 10 at a given timing.
  • the movable core 27 is attracted to close the stationary contacts 25 and 26, thereby forming a short-circuited passage to short-circuit the resistor element 9.
  • a full voltage is applied from the battery 11 to the motor 4 to allow a high electric current to flow through the motor 4.
  • the motor 4 rotates at a high speed with a high-speed rotation of the motor 4 being transferred from the pinion gear 6 to the ring gear 5, thereby cranking the engine.
  • the motor 4 is energized with the electric current limited with the resistor element 9 at an early stage (during a period from a timing at which the main contact MC is closed to another timing at which the auxiliary contact AC is closed) of the operation of the motor 4, thereby alleviating a shock occurring during meshing engagement between the pinion gear 6 and the ring gear 5.
  • the starter 1A takes the form of a structure in which the housing and the flange member, shown in the related art (Patent Publication 1), are not separate from each other and the auxiliary electromagnetic switch 10 is fixedly mounted on the end frame 40 of the motor 4 via the mounting member 50.
  • the starter 1A of the present embodiment has a less limitation in available physical space than that of the related art starter. Therefore, the teachings of the present disclosure can be applied not only to a starter of a large size but also to a starter of a small size, while making it possible to easily manufacture the starter on a mass production basis.
  • the auxiliary electromagnetic switch 10 can be placed in a position such that a whole of the auxiliary electromagnetic switch 10 falls in the area to which the main electromagnetic switch 8 is projected in the axial direction.
  • the main electromagnetic switch 8 and the auxiliary electromagnetic switch 10 can have a smaller projected area on a plane perpendicular to an axis of the motor 4 than that of the main electromagnetic switch 8 and the auxiliary electromagnetic switch 10 that are placed in parallel to each other in areas above the motor 4 at circumferentially spaced positions thereof.
  • no likelihood occurs for the starter 1A to have a remarkably larger installation space than that achieved with a starter having no auxiliary electromagnetic switch 10. This prevents the starter 1A from interfering with an engine block and equipment installed on the engine at an outer circumferential periphery thereof, thereby ensuring an adequate installation space for the starter 1A with respect to the engine.
  • the B-terminal bolt 15 of the electromagnetic switch 8 and the second terminal bolt 30 of the electromagnetic switch 10 are electrically and mechanically connected to one another via the metallic connecting member 34A.
  • the starter 1A of the present embodiment has a further increased vibration proof than that achieved in a case where wires connect both of the bolts 15 and 30 to each other.
  • the auxiliary electromagnetic switch 10 is fixedly mounted on the end frame 40 of the motor 4 via the mounting member 50.
  • the auxiliary electromagnetic switch 10 can be easily fixed to the end frame 40 via the mounting member 50 with no need required for the auxiliary electromagnetic switch 10 to have, for instance, a flange portion or the like to pass screws or bolts.
  • the mounting member 50 is comprised of the band portion 50a, made of a metallic plate material bent in a annular configuration, and the leg portions 50b formed at the both terminal ends of the band portion 50a and, hence it is easy to manufacture the mounting member 50.
  • the mounting member 50 is made of the metallic plate material formed in a simple configuration (such as, for instance, a band-like rectangle shape). This enables the mounting member 50 to be made of metallic raw material with a resultant increase in yield, enabling a reduction in production cost.
  • a starter 1B of a modified form of the second embodiment will be described below with reference to FIG. 10 .
  • the starter 1B of the present modification differs from the starter 1A of the second embodiment in that the starter 1B of the present embodiment includes an auxiliary electromagnetic switch 10B having an axis placed in a position perpendicular to the axis of the main electromagnetic switch 8.
  • the starter 1B can be structured with the main electromagnetic switch 8 having not only a function to open or close the main contact provided in the motor circuit but also a function to drive the shift lever 7 to push the pinion gear 6 to the ring gear 5 and the auxiliary electromagnetic switch 10B merely having a function to short circuit the resistor element 9 of the motor circuit.
  • the auxiliary electromagnetic switch 10B can have an overall length (a length in an axial direction) that is less than that of the main electromagnetic switch 8. As shown in FIG.
  • the auxiliary electromagnetic switch 10B does not protrude in a large extent from an area to which the main electromagnetic switch 8 is projected in an axial direction. This prevents the auxiliary electromagnetic switch 10B from interfering with an engine block or equipment disposed on the engine around a circumferential periphery thereof.
  • FIG. 11 shows a front view of a mounting member of a modified form of the mounting member shown in FIG. 10 .
  • the mounting member 50B includes a annular band portion 50Ba, with which the auxiliary electromagnetic switch 10B is fixedly secured to the end frame 40 of the motor 4, and leg portions 50Bb formed at both ends of the band portion 50Ba.
  • the band portion 50Ba has an inner circumferential periphery formed with circumferentially spaced protrusions 50Bd.
  • the protrusions 50Bd With the band portion 50Ba having the inner circumferential periphery formed with the circumferentially spaced protrusions 50Bd, the protrusions 50Bd are brought into abutting engagement with an outer circumferential periphery of the auxiliary electromagnetic switch 10B. This enables the protrusions 50Bd to be held in pressured contact with the outer circumferential periphery of the auxiliary electromagnetic switch 10B with increased surface pressures. This prevents the auxiliary electromagnetic switch 10B from slipping (in rotation) at the inner periphery of the band portion 50Ba, enabling the auxiliary electromagnetic switch 10B to be reliably fixed in place.
