Description
Technical field
The utility model is related to starter designs and the technical field of manufacture more particularly to a kind of starter to be dialled with the long-life
Fork.
Background technology
In the prior art, an important composition component of the shift fork as starter, is mainly responsible for isolator（Drive gear）
Dial-out and retract, i.e., when electromagnetic switch is powered, switch lever assembly pushes shift fork, to transfering to isolator, complete
Motivation is engaged with engine flywheel ring gear；After successful engine startup, electromagnetic switch power-off, switch lever assembly, which drives, to be dialled
Fork retracts to isolator return.For usual starter when surmounting, the shift fork ring abrasion of shift fork is more serious, has seriously affected starter
Service life.
With the extension of vehicle three guarantees phase, the special vehicles such as bus, Coal Transport repeatedly start particular/special requirement, existing
The starter of shifting fork structure is difficult to meet requirement.
Invention content
The goal of the invention of the utility model is to overcome the above-mentioned insufficient of existing engine shift fork and provide a kind of starter
With long-life shift fork, the service life of starter is effectively raised.
It includes shift fork bar body and shift fork ring that the utility model, which solves technical solution used by its technical problem, described
Shift fork bar body is in upper and lower jag shape structure by the symmetrical connection of left yoke bar, right yoke bar, slit port under shift fork bar body
It is provided at both ends with the pin for installing shift fork ring；The shift fork ring is one compatible with slit port under shift fork bar body
Semi-circular structure is provided with cylindrical hole compatible with the pin of shift fork bar body at shift fork ring two-port.
The shift fork pin hole for assembling shifting fork pin is additionally provided in shift fork bar body described in the utility model.
The center of cylindrical hole at shift fork ring two-port described in the utility model and shift fork ring center are misaligned, eccentricity
Δ is 0.5-1.5mm.
Plane is to transfer to end face on shift fork ring described in the utility model, and the shift fork ring lower plane is to surmount end face, described
The center of the cylindrical hole of shift fork ring to dial-out end face is apart from the center less than cylindrical hole to the distance for surmounting end face.
The utility model has the beneficial effects that：
（1）The utility model is applied to various starter assembly, can greatly prolong the service life of starter；
（2）The utility model novel design, simple for process, the service life of starter greatly prolongs, and using effect is good；
（3）The utility model is applied to planet deceleration starter assembly, will be carried out using the starter of the long-life shift fork
Engine pedestal endurance test makes the service life of starter be promoted to 70000 times by 35000 times, meets car, coal fortune significantly
The requirement of the special operation conditions such as defeated vehicle.

Face, 8, surmount end face, 9, cylindrical hole, 10, rod assembly, 11, shifting fork pin, 12, isolator.
Specific implementation mode
Presently in connection with attached drawing, the technical scheme in the utility model embodiment is clearly and completely described, this attached drawing
For simplified schematic diagram, only illustrate the basic structure of the utility model in a schematic way.
According to Fig. 1, the shift fork ontology 1 of the utility model is equipped with left yoke bar 2, right yoke bar 3, equipped with for stirring
The shift fork ring 4 of isolator is equipped with for by slip ring 4 and left yoke bar 2, the pin 5 that right yoke bar 3 links together to be equipped with and uses
In the pin hole 6 of assembly shifting fork pin.
According to fig. 2, shown in Fig. 3, the shift fork ring 4 of the utility model, which is equipped with, transfers to end face 7, equipped with end face 8 is surmounted, is equipped with two
A cylindrical hole 9, two axis pins 5 for assembling shift fork ring 4, the center of cylindrical hole 9 do not overlap with the center of shift fork ring 4, partially
The heart is away from for Δ, Δ 1.2mm.Dial-out end face 7 when i.e. the shift fork ring 4 is transferred to is small relative to the distance at 4 center of shift fork ring
Surmount distance of the end face 8 for shift fork ring 4 when surmounting.
According to Fig.4, the top of the shift fork ontology 1 of the utility model is matched with electromagnetic switch rod assembly 10, is dialled
Bolt 11 passes through the pin hole 6 of shift fork ontology 1, and is fixed shift fork ontology 1 by axial limiting, slip ring 4 and the list of shift fork ontology 1
Coordinate to the slip ring of device 12.
When electromagnetic switch is powered, rod assembly 10 moves right, and under the leverage of shift fork ontology 1, drives unidirectional
Device 12 moves downward, and completion starter is engaged with engine flywheel ring gear；When starter successfully by engine start after, electromagnetism
Switch circuit breaking, rod assembly 10 retract under the action of spring force to the left inside it, and shift fork ontology 1 is driven to move right, until
Play 12 return of isolator.
