Abstract
The invention discloses a shifting fork assembly for an engine starter of an automobile. The shifting fork assembly comprises a shifting fork and a shifting block, wherein the shifting fork is an integral part; the upper part of the shifting fork is a straight plate part and the lower part of the shifting fork is a bilaterally symmetrical semicircular fork part; the middle of the straight plate part is provided with a positioning pin assembled with the starter; the upper end of the straight plate part is sleeved in a rectangular hole on an electromagnetic switch pull rod of the starter and moves along with the movement of the electromagnetic switch pull rod; and a left shifting block and a right shifting block which are opposite to each other are integrally molded on the inner sides of left and right sides of the lower end of the semicircular fork part and matched with a one-way clutch groove of the starter. The left and right shifting forks of the starter are integrated with a semi-annual shifting block by changing the structure of an internal shifting fork of the starter and a pin shaft is eliminated, so that wear of the shifting fork is restrained. The shifting fork assembly has the advantages of simple and compact structure and high durability.
Description
Technical field
The present invention relates to the automobile engine starting system, be specifically related to engine starter.
Background technique
The Weak hybrid power passenger car is motor to be extinguished fully do not work when meeting traffic light or idling, completely abolishes engine idling condition.When car load needs startup to advance again, Weak hybrid power passenger car idling start-stop electric system responds the quick ato unit of driver's startup command rapidly, the car load normal driving advances, adopting the result of Weak hybrid power idling start-stop function is exactly the Fraquent start of motor, particularly in the many city operating modes of traffic light, the idling of motor is more, the start-stop of motor is more frequent, 5 times of starting reliability that are conventional engines are had a surplus, therefore and the starting reliability of traditional starter motor is 50,000 times, requires Weak hybrid power to reach starting endurance quality more than 250,000 times with starter motor.
Given this, the fork of tradition starter motor is referring to Fig. 1, it is left fork 1 by bearing pin 3, right fork 2 links together with semi-circular pulling block 4 and constitutes, the bearing pin 3 of tradition starter motor fork, left side fork 1, right fork 2 and semi-circular pulling block 4 are separating components, owing to may have foozle during fabrication, when assembling, can there be assembly error again, therefore be assemblied in and be prone to bearing pin 3 when using on traditional starter motor, left side fork 1, right fork 2, and the mutual wearing and tearing between the pulling block 4 four, require starting to reach more than 250,000 times for Weak hybrid power with starter motor, such shift fork structure just can not guarantee the wear-resisting reliability of starter motor fork, cause defective starter easily, thus the fail to start motor.
Summary of the invention
The object of the present invention is to provide the shifting fork assembly of the long motor car engine of a kind of simple in structure, compact, durability with starter motor.
In order to achieve the above object, automotive engine starter shifting fork assembly of the present invention mainly is by changing the structure of the inner fork of starter motor, and with the left and right sides fork and the semi-circular pulling block integrator of starter motor, the cancellation bearing pin suppresses the wearing and tearing of fork.
Technological scheme of the present invention is as follows:
A kind of shifting fork assembly of automotive engine starter, it comprises shift fork and shifting block, it is characterized in that: described shift fork is a single piece, and top is straight plate part, the bottom is symmetrical semicircle fork; There is the locating stud with the starter motor assembling at the middle part of described straight plate part, and the upper end of straight plate part is enclosed within the rectangular opening of starter relay pull bar, and moving with the magnetic switch pull bar;
In the inboard of the lower end of described semicircle fork the right and left, one-body molded have relative left pulling block and right pulling block, an overrunning clutch groove fit of left pulling block and right pulling block and starter motor.
Described left pulling block and right pulling block are the diamond block with thickness, and its thickness face by the rhombus limit carries out face with the overrunning clutch groove of starter motor and cooperates.
By said structure as seen, this fork assembly is with original left fork and right fork integrator, the cancellation bearing pin, original semi-circular pulling block is resolved into left pulling block and right pulling block, and with left pulling block and right pulling block and fork integrator, so just can eliminate the bearing pin of traditional starter motor fork, left fork, right fork and semi-circular pulling block and have foozle during fabrication, when assembling, there is assembly error, avoid wearing and tearing each other, guarantee the reliability of starter motor fork.Further the left and right sides pulling block with the starter motor fork is designed to rhombus, and making itself and overrunning clutch groove is plane contact, thereby reaches the purpose of the durability that improves starter motor.
Description of drawings
Fig. 1 is the structural representation of traditional starter motor fork assembly;
Fig. 2 is the structural representation of the starter motor shifting fork assembly after improving;
Fig. 3 is the sectional view of the starter motor fork after improving;
Fig. 4 is that the starter motor fork assembly after improving is assembled to the schematic representation on the starter motor;
Among the figure: 1, left fork 2, right fork 3, bearing pin 4, semi-circular pulling block 5, fork 6, left pulling block 7, right pulling block 8, magnetic switch 9, locating stud 10, fork assembly 11, overrunning clutch groove
Embodiment:
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Referring to Fig. 2 and Fig. 3, starter motor shifting fork assembly of the present invention mainly is to be fork 5 with the left fork of traditional starter motor fork, right fork integrator, with semi-circular pulling block resolve into left pulling block 6 and right pulling block 7 and with fork 5 integrators, and the left pulling block 6 and the right pulling block 7 of starter motor fork be designed to rhombus.
Its concrete shift fork 5 is single piece, top is straight plate part 51, the bottom is symmetrical semicircle fork 52, there is the locating stud 9 with the starter motor assembling at the middle part of its straight plate part 51, the upper end of straight plate part 51 cooperates with starter relay, be enclosed within the rectangular opening of starter relay pull bar, and moving with the magnetic switch pull bar.In the inboard of the lower end of semicircle fork 52 the right and left, one-body molded have relative left pulling block 6 and a right pulling block 7, and left pulling block 6 and right pulling block 7 are for having the diamond block of thickness, and its thickness face by the rhombus limit carries out face with the overrunning clutch groove of starter motor and cooperates.
Referring to Fig. 4, in the course of the work, when starter relay 8 adhesives, when magnetic switch 8 drive fork assemblies 10 are the center rotation with locating stud 9, fork left side pulling block 6 and the A plane of right pulling block 7 and the groove side plane contact of overrunning clutch 11 in overrunning clutch 11 grooves, promoting overrunning clutch 11 moves, and the rotating force that starter armature produces is delivered to flywheel and pilots engine, along with moving of overrunning clutch 11, the left pulling block 6 of rhombus and A plane that shifting block 7 arranged all the time with the groove side plane contact of overrunning clutch 11.
