[0056] Referring to Figures 1 and 2, there is shown a starter 1 according to an embodiment of the present invention. The starter 1 includes: a motor 2 for generating output torque, and an electromagnetic switch 3 arranged in an excitation circuit (also called a motor circuit) EC of the motor 2 for closing or opening a main contact MC (described below ); connected with the motor 2 to reduce the speed reduction gear set 4; the output shaft 5, the output torque of the motor 2 is transmitted to the output shaft through the reduction gear set 4; Gear 6; the electromagnetic clutch 7 that can establish or interrupt the torque transmission between the motor 2 and the output shaft 5; and the delay circuit 8 (see Fig. 2 ) that is arranged in the excitation circuit EC, can make the electromagnetic switch 3 after the electromagnetic clutch is energized power on for a predetermined delay time. The starter 1 can be applied to the automatic stop and restart system of the engine (also called...

[0092] In the starter 1 of the second embodiment, the structure of the electromagnetic clutch 7 is designed such that the clutch plate 37 can move a given axial stroke (equal to the distance between the end surface of the clutch housing 36 and the clutch plate) in the axial direction when attracted by the electromagnet. The clutch disc 37 between 37 is used as the axial gap for axial displacement), or the clutch coil 35 is designed such that its attractive force makes the clutch disc 37 attracted by the electromagnet to enter the engaged state before the armature 11 starts to rotate.

[0093] That is to say, the electromagnetic switch 3 that can close or open the main contact MC is designed so that the main contact MC is not closed when the electromagnetic coil 13 is energized, but when the movable core 15 moves a given axis due to the attractive force of the electromagnet. It closes only after the stroke. Therefore, there is a time delay between the energization of the electr...

Abstract

The present invention discloses a starter motor 1 comprising a motor 2 equipped with an armature 11, an electromagnetism switch 3, a main contact (MC) capable of closing or cutting an electric circuit (EC) of motors, an electromagnetic clutch 7 used to linking or cutting the torque transfer path of said starter motor 1. The starter motor 1 further comprises a time delay mechanism 7, 8, which allows the foundation of said torque transfer path between the motor 2 and engine ring gears 30 while clutch slice 37 is activated into linkage state before the armature 11 runs.

Description

technical field [0001] The present invention relates to a starter for an engine, and in particular, to a constant mesh type starter having a pinion gear which is constantly meshed with a ring gear of the engine. Background technique [0002] In recent years, more and more automobiles have tended to adopt engine control systems (also called idle stop systems, eco-run systems, etc.) that automatically control engine stop and restart. The structure of this engine control system is designed to automatically stop the engine and then automatically restart the engine when the car stops at an intersection or due to traffic jams. It has advantages for improving automobile fuel consumption and exhaust emissions. [0003] Among the starters used in such an engine control system, a belt drive type starter has been known so far, which can be used to start such an engine. This starter arrangement consists of a starter pulley which is kept connected by a belt to the crankshaft pulley of ...
