Embodiment
Describe the location shift fork of a kind of specific embodiment disclosed in this invention in detail below in conjunction with accompanying drawing.Yet, the present invention should be understood as and be not limited to this mode of execution described below, and the other technologies combination that technical concept of the present invention can be identical with those known technologies with other known technologies or function is implemented.
In the following description, for clear structure of the present invention and the working method of showing, to be described by all multidirectional words, but should be, and not should be understood to word of limitation with Word Understandings such as " preceding ", " back ", " left side ", " right side ", " outward ", " interior ", " outwards ", " inwardly ", " axially ", " radially " for making things convenient for term.In addition, the front portion of close in the axial direction motor in part position, the main finger of employed in the following description " preceding " speech or motor ring gear.Similarly, " back " speech mainly refers to these parts near the back cover portion of starter motor, i.e. another zone opposite with motor on the direction.
As shown in Figure 2, Fig. 2 is the structural representation of starter motor involved in the present invention.The difference of disclosed starter motor has been to install one and has had the magnetic switch 22 of water-proof function in this starter motor and the prior art.This magnetic switch 22 comprises coil, moving core, Returnning spring, shift fork 25 and location shifting fork device 21.This magnetic switch 22 is positioned over the top of starter motor, is sealed by casing 23.Because starter motor used in the prior art, when it started, engine flywheel was meshed with starter pinion, and wherein position engaged is between Front Cover Bearing and planet wheel seat axle bush, therefore protecgulum 24 of the prior art must have opening, reserves certain space and gives engine flywheel.Simultaneously because protecgulum 24 contacts with the external world, so starter motor has water droplet fog etc. inevitably and enter starter motor inside in the real-world operation process, cause the magnetic switch 22 can't normal operation easily.
Design of the present invention is to provide a kind of magnetic switch 22 with water-proof function, and this magnetic switch 22 is installed a location shifting fork device 21, and an end of this location shifting fork device 21 contacts with shift fork 25, and the other end is used to prevent that water droplet fog from entering magnetic switch.One end of this shift fork 25 is connected with moving core, and the other end is used to promote clutch and travels forward.An end that is connected with moving core when this shift fork 25 is driven when mobile backward by moving core, and shifting fork device 21 is spacing because the intermediate portion of this shift fork 25 is positioned, and therefore forms a leverage.Preferably, in the present embodiment, the intermediate portion of shift fork 25 is designed to a fulcrum 204 that protrudes, can contacts better in order to make shift fork 25 and shift fork locate 21.Similarly, this shift fork fulcrum 204 also can be designed as the fulcrum of a depression or other modes and shift fork and locatees 21 and contact.
The detailed structure schematic representation of shift fork location 21 sees also accompanying drawing 3.As shown in Figure 3, this shift fork location 21 is made up of two-part, comprises shift fork sealing block 201 and shift fork piece 202.Shift fork sealing block 201 comprises a waterproof boss 203.This shift fork sealing block 201 is made by sealing material, preferably the rubber-like elastomeric material.Elite in the present embodiment with nitrile butadiene rubber as schematically illustrating.This shift fork sealing block 201 is assemblied in the protecgulum, and the shape of its each face and size can be carried out adaptability design according to the different model of starter motor, only need satisfy this shift fork sealing block 201 and fit tightly with magnetic switch and casing 23 and get final product.One end of waterproof boss 203 is connected with shift fork sealing block 201, and the other end comprises at least one mounting hole 205.This mounting hole 205 can be one or more.Preferably, the design of this mounting hole 205 is two apertures that are positioned on the waterproof boss 203 as shown in Figure 3.Mounting hole 205 is used for placed shifting fork piece 202.The design of shift fork piece 202 is spacing for shift fork 205 is carried out, so shift fork piece 202 adopted the rigid material different with shift fork sealing block 201, as unit of plastic etc.In the present embodiment, comprise at least one connecting pin 206 on the shift fork piece 202.Connecting pin 206 is to be used to be positioned in the mounting hole 205, and therefore, the quantity of connecting pin 206 and shape size are corresponding with mounting hole 205.
A kind of shift fork piece 202 disclosed in this invention comprises two connecting pins 206 as shown in Figure 3 on this shift fork piece 202, the shape of the disconnected tangent plane of connecting pin 206 is rounded, and convenient in order to make when inserting mounting hole 205.It is conical that this connecting pin 206 slightly is.Comprise also on the shift fork piece 202 that 207, two connecting pins 206 of a plate all are connected with this connecting plate 207, its effect is keep connecting pin 206 fixing.
What be somebody's turn to do in this specification is preferred embodiment of the present invention, and above embodiment is only in order to illustrate technological scheme of the present invention but not limitation of the present invention.All those skilled in the art all should be within the scope of the present invention under this invention's idea by the available technological scheme of logical analysis, reasoning, or a limited experiment.
