Abstract
The utility model discloses a synchronous ware of a second gear, establish the clutch collar outside the tooth hub including tooth hub and cover, tooth hub outer lane is equipped with a plurality of external spliness and three evenly distributed's axial groove, the clutch collar inner circle be equipped with with external splines complex internal spline, characterized by: axial tank bottom portion width is greater than its top width, the axial inslot is equipped with the slider, the slider includes steel ball and guide block, the guide block comprises with extending to put up the main part, the steel ball riveting is in the main part, be equipped with the spring between steel ball and the main part. The utility model discloses because axial tank bottom portion width is greater than its top width, has effectively prevented droing of slider, in addition, increased sharp transition district between back taper tooth and the internal spline denticle, the back taper tine length has prolonged to the elimination is shifted the in -process and is interfered, improves the smooth and easy nature of shifting.
Description
Technical field
This utility model relates to a kind of one or two grades of lock units.
Background technology
At present, lock unit has been widely used in the automotive transmission of mechanical gear transmission.Use due to it so that the performance of mechanical type manual speed-changer is substantially improved, not only makes gear shift light, it is to avoid impact, makes the average life of variator and whole power train also be improved simultaneously, is also beneficial to improve dynamic property and the fuel economy of automobile.Existing lock unit is in assembling and gearshift procedure, slide block easily comes off, so that lock unit breaks down, additionally, steel ball and guide block split, putting in circular hole by steel ball general assembly when, steel ball end withstands tooth set, and the two ends of steel ball and tooth hub are withstood by spring in lower section, during installation, steel ball is ejected by the reason due to spring, being not easy to assembling, steel ball easily skids off from guide block simultaneously, and production efficiency is the lowest.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model be to provide a kind of anti-limited slip block come off, easy for installation and be prevented from guide block deformation one or two grades of lock units.
To this end, this utility model uses following scheme to realize:
One or two grades of lock units, including tooth hub and the clutch collar being set in outside tooth hub, described tooth hub outer ring is provided with some external splines and three evenly distributed axial grooves, described clutch collar inner ring is provided with the internal spline coordinated with external splines, it is characterized in that: described axial groove bottom width is more than its top width, is provided with slide block in described axial groove, described slide block includes steel ball and guide block, described guide block is made up of main body and expansion rack, and described steel ball is riveted in main body, is provided with spring between described steel ball and main body.
Described expansion rack is located at main body both sides, and expansion rack bottom has the kink bent inwards.
After using technique scheme, owing to axial groove bottom width is more than its top width, effectively prevent coming off of slide block, steel ball is riveted in the main body of guide block, spring is located between steel ball and main body, making synchronizer key is integral type structure, convenient installation, decreases steel ball loss, improve general assembly efficiency and productivity effect, it addition, the expansion rack of main body both sides makes guide block structure more firm, effectively prevent guide block from deforming.
Accompanying drawing explanation
This utility model has a drawings described below:
Fig. 1 is construction profile figure of the present utility model；
Fig. 2 be in this utility model slide block partly cut open structural representation.
Detailed description of the invention
As depicted in figs. 1 and 2, one or two grades of lock units that this utility model provides include tooth hub 1 and the clutch collar 2 being set in outside tooth hub 1, tooth hub 1 outer ring is provided with some external splines 3 and three evenly distributed axial grooves 4, clutch collar 2 inner ring is provided with the internal spline 5 coordinated with external splines 3, axial groove 4 bottom width is more than its top width, it is provided with slide block in axial groove 4, slide block includes steel ball 6 and guide block, guide block is made up of main body 7 and expansion rack 8, steel ball 6 is riveted in main body 7, spring 9 it is provided with between steel ball 6 and main body 7, expansion rack 8 is located at main body 7 both sides, and expansion rack 8 bottom has the kink 10 bent inwards.
In the present embodiment, owing to axial groove 4 bottom width is more than its top width, effectively prevent coming off of slide block, steel ball 6 is riveted in the main body 7 of guide block, spring 9 is located between steel ball 6 and main body 7, making synchronizer key is integral type structure, convenient installation, decreases steel ball 6 and loses, improve general assembly efficiency and productivity effect, it addition, the expansion rack 8 of main body 7 both sides makes guide block structure more firm, effectively prevent guide block from deforming.
Claims (2)
1. one or two grades of lock units, including tooth hub and the clutch collar being set in outside tooth hub, described tooth hub outer ring is provided with some external splines and three evenly distributed axial grooves, described clutch collar inner ring is provided with the internal spline coordinated with external splines, it is characterized in that: described axial groove bottom width is more than its top width, is provided with slide block in described axial groove, described slide block includes steel ball and guide block, described guide block is made up of main body and expansion rack, and described steel ball is riveted in main body, is provided with spring between described steel ball and main body.
One or two grades of lock units the most according to claim 1, is characterized in that: described expansion rack is located at main body both sides, and expansion rack bottom has the kink bent inwards.
