Embodiment Construction

[0032] Overall starter arrangement

[0033] refer to figure 1 , in at least one embodiment, a vehicle starter 100 includes an electric motor 102 and a solenoid 110 . Although not in figure 1 shown in, with reference to the above Figure 15 Similar to the conventional starter assembly 200 described, the starter 100 also includes a drive mechanism and a pinion. exist figure 1 The electric motor 102 in the embodiment of the present invention is positioned in a motor circuit 104 configured to connect the electric motor to a vehicle battery (not shown) via a B+ terminal. A solenoid 110 is positioned in the motor circuit 104 to facilitate connecting the motor to the vehicle battery. The solenoid includes a pull coil 112 , a hold coil 114 , a push rod 116 and an ignition switch 118 .

[0034] figure 1 The motor circuit 104 includes a first current path 106 and a second current path 108 configured to provide electrical energy to the motor 102 . The first current path 106 ...

Abstract

A solenoid for a vehicle starter comprises a spool including a first coil bay, a second coil bay, and an interior passage defining an axial direction. A first coil is positioned in the first coil bay of the spool, and a second coil positioned in the second coil bay of the spool. A plunger is positioned within the interior passage of the spool and configured to move in the axial direction when the first coil is energized. The first coil bay is positioned adjacent to the second coil bay in the axial direction. The spool further includes two end flanges and a middle flange. The middle flange separates the first coil bay from the second coil bay.

Description

technical field [0001] The present invention relates to the field of vehicle starters, and more particularly, to solenoids for starter motor assemblies. Background technique [0002] Starter motor assemblies that assist in starting an engine, such as an engine in a vehicle, are known. Traditional starter motor components such as Figure 15 shown. Figure 15 The starter motor assembly 200 includes a solenoid 210 , an electric motor 202 and a drive mechanism 204 . The solenoid 210 includes a coil 212 that is energized by the battery when the ignition switch is closed. When solenoid coil 212 is energized, push rod 216 moves in a linear direction, causing shift lever 205 to pivot and forcing pinion 206 into mesh with a ring gear (not shown) of the vehicle engine. When the push rod 216 reaches the push rod stop, the electrical contacts close, connecting the motor 202 to the battery. The energized motor 202 then rotates and provides output torque to the drive mechanism 204 . T...
