Embodiment Construction

[0015] figure 1 An exemplary embodiment of an internal combustion engine is shown. Internal combustion engine 12 includes a starter motor 14 and a ring gear 16 having a plurality of ring gear teeth 18 . The vehicle starter includes a starter motor 14 comprising an electric motor that engages and rotates a ring gear 16 to initiate operation of the internal combustion engine 12 . The starter motor 14 includes a motor housing 15 and a handpiece or pinion housing 17 . Solenoid 20 is operatively coupled to starter motor 14 . Starter motor 14 includes an output shaft (not shown) that supports a one-way clutch and a pinion gear (also not shown) that selectively engages ring gear 16 .

[0016] Such as figure 2 with 3 As shown, the solenoid 20 includes a housing 23 surrounding a first coil 40 , a second coil 42 and a plunger assembly 44 . The first coil 40 is held on a first bobbin 80 and the second coil 42 is held on a second bobbin 82 . The first bobbin 80 includes: a substan...

Abstract

A solenoid for a motor vehicle starter motor (14) includes at least one coil (42) wound on at least one spool (82), the at least one coil (42) defines a toroidal space (98) encircling the at least onecoil. A stop member (70) is positioned adjacent to the at least one spool. A diode holder (110) is positioned in the toroidal space defined by the at least one coil, and a diode (140) is positioned in the diode holder. The diode includes a cylindrical body (144), a first lead (146) extending from a first end of the cylindrical body, and a second lead (148) extending from a second end of the cylindrical body. The cylindrical body of the diode is retained by the diode holder within the toroidal space, and the first lead of the diode extends out of the toroidal space and is electrically connected to the stop member.

Description

technical field [0001] This application relates to the field of vehicle starters, and more particularly to solenoids for starter motor assemblies. Background technique [0002] Starter motor assemblies are well known which assist in starting an engine, such as an engine in a vehicle. A traditional starter motor assembly includes a solenoid, an electric motor and a transmission mechanism. The solenoid consists of a coil that is energized by the battery when the ignition switch is closed. When the solenoid coil is energized, the plunger moves in a linear direction, causing the shift lever to pivot and force the pinion into engagement with the ring gear of the vehicle's engine. When the plunger reaches the plunger stop, the electrical contacts close, connecting the motor to the battery. The energized electric motor in turn rotates and provides output torque to the drive mechanism. The drive mechanism transmits the torque of the electric motor through various drive members t...
