Definitions
- the invention relates to the arrangement of the movable core of the electromagnet of the switch of the starter for internal combustion engines with connection of the terminal board and electric motor contacts
- the starters for internal combustion engines are designed so that the electromagnet for disengaging the pinion in the ring gear of the flywheel of the internal combustion engine with the switching contacts of the main current of the starter is arranged parallel to the main axis of the electric motor of the starter, the cover of the electromagnet with contacts being the terminal board of the Starter forms.
- the pinion is then disengaged by the action of the core of the electromagnet on the pinion by means of a most commonly two-armed lever.
- a solution is also known where the release electromagnet is arranged in the axis of the starter pinion and the contacts of the switch are connected to the terminals which are insulated on the rear cover of the starter, these terminals not being arranged in an assembly group.
- the contact of the electric motor is insulated on the wall of the rear cover and the contact of the terminal board is fixed to the body of the rear cover by means of a screw.
- the disadvantage of the device for disengaging the pinion with the lever mechanism is its complexity and the occurrence of frictional resistance in the lever mechanism, which consequently have increased energy demands for the generation of a sufficient disengaging force.
- Disadvantage of the arrangement of the release electromagnet in the axis is the ease of assembly and the securing of the core bolt by riveting the core end.
- Defects of the known solutions eliminated the arrangement of the movable core of the electromagnet of the starter switch for internal combustion engines with connection of the clipboard and electric motor contacts according to the invention, where the electromagnetic switch is mounted in the cavity of the rear cover and in the axis of the starter the movable core is included a bolt mounted, which is guided in the cavity of the movable core through the first chuck and the second chuck.
- the essence of the invention is that the pressure plate is inserted into the second chuck with securing lugs cut transversely in the axial axis.
- the bolt of the movable core is guided through the opening of the pressure plate, with which the pressure plate is locked against being pushed out of the second chuck.
- the contact bridge with the insulating washer is drawn on the outside diameter of the second chuck and a contact spring is put on the outside diameter of the pressure plate.
- the track spring is mounted in the first chuck, the second end of which is pressed against the rear end face of the bolt of the movable core.
- the front end face of the bolt is prepared for guiding the tie rod.
- the return spring of the movable core is supported at one end on the support plate of the electromagnetic switch and at the second end the movable core is pressed into the rest position.
- the bolt of the movable core is secured in the assembled position with a self-locking circlip with a washer, which is arranged in the cavity of the pressure plate, which is supported with its outer conical surface on the inner conical surface of the rear cover and holds the assembled movable core in the rest position.
- the contact bridge switches through the contact of the terminal board with the contact of the electric motor.
- the contact of the terminal board is injected into the plastic of the terminal board body together with the output screw, which is recessed with the head in the cavity formed at the second contact end and is technologically ensured by means of an incision on the exited outer end face of the cavity.
- the outer end face of the cavity extends over the surface of the connection surface of the terminal board and the connection cable lug of the power supply line with the nut lies directly on this end surface.
- the contact for the connection of the electric motor is injected or inserted into the insulating liner by means of a through-pressing formed on the lower part of the insulating liner.
- the pressure jumps into the recess on the contact surface of the insulating liner, the insulating liner also being plugged into the contact by means of incisions on the lower side of the insulating liner on the emerged end region of the jacket of the electromagnetic switch.
- connection of the terminal board contact is the technological advantage of the connection without the need for galvanic connection of the output screw to the contact body, because the current is led directly from the connection shoe to the conductive surface of the contact and the screw connection is only used to generate the necessary pressure.
- connection of the contact of the electric motor is the attachment of the contact to the body of the electromagnetic switch without the need to use further connecting parts such as rivets or screws.
- the contact is only fixed by simply attaching a molded part made of insulating material.
- FIG. 1 shows the section through the rear cover of the
- Fig. 1a shows an axonometric view of the pressure plate with locking lugs
- Fig. 2 shows an axonometric view of the contact of the electric motor with the insulating lining, pushed onto the end face of the jacket of the electromagnetic switch
- Fig. 3 shows an axonometric view of the individual insulating lining
- Fig. 3a shows an axonometric view of the contact for the connection of the electric motor.
- Fig. 4 is the overall view on the terminal board of the starter and in Fig. 5 is an axonometric view of the contact of the terminal board with a recessed output screw.
- the movable core 10 acts with axial force by means of a bolt 15 which is guided in the cavity 10.1 of the core 10 through the first chuck 24 and through the second chuck 22, which e.g. are made of molding compound.
- the pressure plate 14 is inserted into the second chuck 22 with securing lugs 211 cut transversely in the axial axis (FIG. 1 a).
- the bolt 1_5 of the movable core 10 is passed through the opening of the pressure plate 14.
- the bolt 15 of the movable core 10 locks the locking lugs 21.1 after insertion into the pressure plate 14 and thus secures the pressure plate 14 against being pushed out of the second chuck 22.
- On the outer diameter of the second chuck 22 is the contact bridge 12 with an insulating washer H and on the Outside diameter of the pressure plate 14, the contact spring 13 is arranged.
- In the first chuck 24 there is mounted the engagement spring 16, which presses with the second end onto the rear end face of the bolt 15 of the movable core 1_0.
- the front end face of the bolt 1J5 is prepared for the guidance of the tie rod 1_9.
- the return spring 18 of the movable core 1_0 is supported with one end on the support plate 25 of the electromagnetic switch 2 and with the second end presses the movable core 1Q_ into the rest position.
- the bolt 1_5 of the movable core 1_0 is secured in the assembled position with a self-locking locking ring 20 with a washer 21, which is arranged in the cavity of the pressure plate 14.
- the pressure plate 14 is supported with its outer conical surface 14.3 (FIG. 1 a) on the inner conical surface of the cover 23 and holds the assembled movable core 10 in the rest position.
- the contact bridge 12 switches through the contact 6 of the terminal board 5 to the contact 3 of the electric motor (FIGS. 4 and 5).
- the contact 6 of the terminal board 5 is injected into the plastic mass of the body of the terminal board 5 together with the output screw 7.
- the output screw 7 is let in at the second end 6 4 of the contact 6 with the head 7 'in the cavity 6 formed and is technologically ensured with an incision 6 5 formed on the outer emerged end face 6 5.
- the outer end face 6.5 passes over the surface 6.3 of the connection surface of the Terminal boards 5 above and to this emerged end face 6J5, the connection shoe 8 of the power supply line with the nut 9 (FIG. 1) lies directly on.
- the contact 3 for the connection of the electric motor is injected or is inserted into the insulating chuck 4 and by means of the press-through 3 ⁇ 4 formed on its lower part 3 5, the jumps into the recess 3 5 on the contact surface 32 of the insulating chuck 4.
- the insulating lining 4 is also connected to the contact 3 by means of cuts 3J formed on the lower side of the insulating lining 4 . on the leaked front part 2 of the jacket 2J . of the electromagnetic switch 2 postponed.
- the movable core 1_0 of the electromagnetic switch 2 After switching the electromagnetic switch 2, if the pinion of the starter, not shown, is engaged in the engagement with the ring gear, the movable core 1_0 of the electromagnetic switch 2 is in the engaged state and the return spring 18 is pressed. The current from the cable lug 8 is fed directly via the end face 6 5 to the contact 6 of the terminal board 5 via the switched contact bridge 12 to the contact 3 of the electric motor and the starter is operated at full power.
- the electric motor of the starter rotates with a reduced torque from permanent magnets with high remanence, the rotational movement is transmitted to the pinion of the starter.
- the release rod 19 acts against the movement of the bolt 15 .
- the engagement spring 1_8 is pressed until the rear end face 15.1 of the bolt 1_5 of the movable core 10 rests against the shoulder 24.1 of the first chuck 24 and the connection of the contacts 6 of the terminal board 5 and the contact 3 for connecting the electric motor is not permitted.
- the engagement spring 16 is released and the contact bridge 12 switches the contacts 6 and 3 through and the starter is put into operation at full power.
- the return spring 18 is arranged, which resets the movable core 10 in the rest position.
- the movable core 1_0 moves back, the outer conical surface of the pressure plate 14 comes into contact with the inner conical surface of the cover 23, the movable core continues the movement the contact spring 13 is pressed until the end of the bolt 15 covers the distance from the surface of the cover 23 and rests against it.
