Slot, slide block slot is interior to be equipped with sliding block, and above-mentioned automobile synchronizer has the following disadvantages：1, the tooth of tooth hub external splines is just as size
, and the spacing of tooth adjacent after inside and outside spline fitted is very small, although improving shift flexibility in this way, tooth hub
The phenomenon that it is easy to appear latches with tooth set；2, steel ball and main body are separate structure, and steel ball is put into main body when general assembly
Circular hole in, tooth set is withstood at steel ball end, and lower section is withstood the both ends of steel ball and tooth hub by spring, and when installation will due to spring
Steel ball pops up, and is not easy to assemble, while steel ball is easy to skid off from guide block, and production efficiency is very low；3, slide block structure is simple, intensity
It is not good enough yielding, and sliding block and slide block slot contact surface are too small, are not sufficiently stable, are easy to fall off；4, the lubricant effect of sliding block is poor, warp
It often needs plus lubricating oil, refueling process is very cumbersome.
Invention content
In view of the deficiency of background technology, technical problem to be solved by the invention is to provide one kind preventing latch, prevents steel
Ball falls off, slide block structure is more stable and firm and the better automobile synchronizer of lubricant effect.
For this purpose, the present invention is adopted the following technical scheme that realize：
A kind of automobile synchronizer, including tooth hub and the tooth set being set in outside tooth hub, tooth hub outer ring is equipped with external splines, the tooth
Set inner ring is equipped with the internal spline coordinated with external splines, and tooth hub outer ring is additionally provided with the slide block slot of three circumference equal dividings, the cunning
Sliding block is equipped in block slot, it is characterized in that：There is the external splines multigroup wide tooth, multigroup wide tooth circumference equal dividing to be set to outside tooth hub
It encloses, there is the narrow tooth coordinated with wide tooth on the internal spline, three arc oil guide grooves are equipped on the tooth hub front-back.
The sliding block includes main body, holder and steel ball, and the steel ball is riveted in main body, is set between the main body and steel ball
There is spring, the branch is set up in main body both sides, and holder lower part has the bending part to bend inwards.
The arc groove communicated with arc oil guide groove, the arc on the same face are equipped on the main body front-back
Oil guide groove and arc groove form circular passage, and the arc groove is equipped with the through-hole of connection body interior.
The slide block slot is oval, and it is oval that the main body is placed in the part in slide block slot.
The bottom part body is equipped with oil filler point.
Spacing between the adjacent wide tooth and narrow tooth is 0.5-2mm.
Every group of wide tooth includes 2-4 wide teeth.
After adopting the above technical scheme, there is external splines wide tooth, internal spline to have the narrow tooth coordinated with wide tooth, inside and outside flower
The spacing of adjacent tooth is 0.5-2mm after key cooperation, ensures also to effectively prevent latch while flexibility；Steel ball is riveted on
In main body, spring is set between steel ball and main body, so that synchronizer key is an integral structure, is facilitated installation, reduces steel ball damage
It loses, the holder of main body both sides keeps slide block structure more secured, sliding block is effectively prevent to deform, and slide block slot is oval, and main body is placed in
Part in slide block slot is oval, increases the contact area of sliding block and slide block slot, and structure is more stablized, and anti-limited slip block is de-
It falls；In addition, the arc oil guide groove and arc groove on the same face form circular passage, arc groove is equipped with connection body interior
Through-hole so that lubricating oil can flow into sliding block, and steel ball is made to be chronically at lubricating status, and lubricant effect is more preferable, bottom part body
Equipped with oil filler point, primary oil i.e. available a very long time need to be only noted when mounted, avoids cumbersome sliding block refueling process.
Description of the drawings
