Description
Technical field
The present invention relates to starter fields, and specifically a kind of starter, which is used, drives cap assembly.
Background technique
Starter is to drive the rotation of internal combustion engine flywheel ring gear, realizes the direct current generator of vehicle.Current domestic commercial vehicle
The mill teeth failure of upper starter more takes place frequently, and phenomenon of the failure is the driving gear and engine of starter when starting engine
Flywheel ring gear static state when there is tooth top tooth, cannot normally engage, starter high speed rotation, driving gear and flywheel ring gear end face
Friction, issues strong cacophony, engine can not normally start；Driving gear is equivalent to milling cutter in milling flywheel teeth at this time
Circle, because this fault mode is known as mill teeth in the industry.Its consequence is that flywheel ring gear is bad by milling, sometimes starter driving gear
Also it scraps simultaneously, replacement flywheel ring gear is time-consuming and laborious, influences automobile normal operation.
Due to not studying very well this problem, its Producing reason is also not it is clear that repair mill teeth failure general
It is all direct change flywheel ring gear, the flywheel ring gear newly changed can damage again after a period of use, so that mill teeth is at industry
Problem does not solve fundamentally in the prior art, especially positively engaging starter.
For positively engaging starter, engagement process are as follows: after ignition switch closure, starter relay is obtained
The dynamic iron core of electricity, electromagnetic switch pushes shift fork one end, pushes free-wheeling assembly along in drive shaft by the fulcrum other end
Helical spline it is mobile.Free-wheeling assembly is one-way clutch and the combination for driving gear, in the Turbo Flora of drive shaft
Under the action of key helix, free-wheeling assembly does axial movement and radial rotating；In this section of stroke, compression electromagnetism is opened
The return spring in the Central Shanxi Plain, promotion free-wheeling assembly is to flywheel movement, and based on design in this way, there are two types of meetings is happened, and one
Kind is that driving gear is just directly entered flywheel to upper flywheel ring gear tooth socket, starts engine.Another kind occurs as soon as above-mentioned tooth
Apical tooth phenomenon, this when, shift fork can push down engagement spring, guarantee that dynamic iron core continues to move to, then in this case, sliding tooth
The tooth of wheel does not enter in flywheel ring gear still, and when the main contacts of electromagnetic switch is connected, motor rotates, and the rotation speed of motor depends on
Apical tooth pressure between driving gear and flywheel ring gear.It drives gear under the collective effect of engagement spring and helical spline, drives
Moving gear will slide into flywheel ring gear, start engine.
Based on problem above, how using simpler, low cost method or structure to solve the problems, such as mill teeth, be present life
Required for production.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of drive shaft that can effectively solve the problem that mill teeth is total
At.
To achieve the goals above, the technical solution adopted by the present invention is
