Abstract
The utility model discloses a kind of synchronizer of automobile gearbox, comprise engaging gear, clutch collar, gear hub and synchronizing ring, described clutch collar and gear hub are intermeshing by interior external splines, it is characterized in that: described gear hub outer peripheral surface is provided with erection column, described erection column is provided with elastic clip, described elastic clip is bent to form by elastic metallic, it has two side and a circular arc top is installed, described installation side is clipped on erection column both sides, described clutch collar inner peripheral surface is provided with the arc groove mating with circular arc top, described synchronizing ring outer peripheral surface extends to form gear ring diametrically, the height of described gear ring is higher than clutch collar.This synchronizer work is more stable and more durable.
Description
Technical field
The utility model relates to the synchronizer on a kind of automobile gearbox.
Background technique
Synchronizer is the vitals in automobile gearbox, and it makes the gearshift of gearbox in automobile traveling process that the impact of between cog not occur, and reaches smooth and easy shift process stably, to extend gear life and to reduce noise.Synchronizer is mainly made up of clutch collar, gear hub, synchronizing ring and shifting component, and wherein shifting component comprises locating stud, spring and slide block, and locating stud is by spacing slide block on gear hub, and spring coordinates clutch collar is applied to latch functions with slide block.But this shifting component structure is comparatively complicated, and the cooperation between locating stud, spring and slide block easily goes wrong, and easily damages, and can affect the working stability of synchronizer.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of work synchronizer of stable and more durable automobile gearbox more.
For this reason, the utility model is realized in the following way: a kind of synchronizer of automobile gearbox, comprise engaging gear, clutch collar, gear hub and synchronizing ring, described clutch collar and gear hub are intermeshing by interior external splines, it is characterized in that: described gear hub outer peripheral surface is provided with erection column, described erection column is provided with elastic clip, described elastic clip is bent to form by elastic metallic, it has two side and a circular arc top is installed, described installation side is clipped on erection column both sides, described clutch collar inner peripheral surface is provided with the arc groove mating with circular arc top, described synchronizing ring outer peripheral surface extends to form gear ring diametrically, the height of described gear ring is higher than clutch collar.
Described installation side is provided with fixed hole, and described erection column both sides are provided with the fixed projection corresponding with fixed hole, and described fixed projection is through fixed hole.
In the utility model, elastic clip is with the function of background technique medi-spring and slide block, because elastic clip is bent to form by elastic metallic, there is very high integrity, therefore it has very high intensity, and can improve the spring force larger than spring, makes synchronizer more durable and more stable, and the gear ring in synchronizing ring can prevent that clutch collar from sliding axially in process and come off from gear hub, further improve the stability of synchronizer work.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model Elastic folder.
Embodiment
With reference to accompanying drawing, the synchronizer of this automobile gearbox, comprise engaging gear 1, clutch collar 6, gear hub 3 and synchronizing ring 8, described clutch collar 6 is intermeshing by interior external splines with gear hub 2, described gear hub 2 outer peripheral surfaces are provided with erection column 3, described erection column 3 is provided with elastic clip 5, described elastic clip 5 is bent to form by elastic metallic, it has two side 11 and a circular arc top 10 is installed, described installation side 11 is clipped on erection column 3 both sides, described clutch collar 6 inner peripheral surfaces are provided with the arc groove 7 mating with circular arc top, described synchronizing ring 8 outer peripheral surfaces extend to form gear ring 9 diametrically, the height of described gear ring 9 is higher than clutch collar 6, described installation side 11 is provided with fixed hole 12, described erection column 3 both sides are provided with the fixed projection corresponding with fixed hole 12 4, described fixed projection 4 is through fixed hole 12, fixed projection 4 can make elastic clip 5 more solid and reliable with being connected of erection column 3 with the cooperation of fixed hole 12.Under neutral position state, the circular arc top 10 of elastic clip 5 withstands in the arc groove 7 of clutch collar 6, for clutch collar 6 provides locking effect; Under gearshift state, selector fork moves axially with clutch collar 6,6 of clutch collars drive elastic clip 5 upper ends to swing in the same way, thereby promote synchronizing ring 8, make the conical ring close contact of synchronizing ring 8 and engaging gear 1, and rely on frictional force synchronously to rotate, make clutch collar 6 smooth and easyly realize gearshift with engaging gear 1 socket.
Claims (2)
1. the synchronizer of an automobile gearbox, comprise engaging gear, clutch collar, gear hub and synchronizing ring, described clutch collar and gear hub are intermeshing by interior external splines, it is characterized in that: described gear hub outer peripheral surface is provided with erection column, described erection column is provided with elastic clip, described elastic clip is bent to form by elastic metallic, it has two side and a circular arc top is installed, described installation side is clipped on erection column both sides, described clutch collar inner peripheral surface is provided with the arc groove mating with circular arc top, described synchronizing ring outer peripheral surface extends to form gear ring diametrically, the height of described gear ring is higher than clutch collar.
2. the synchronizer of automobile gearbox according to claim 1, is characterized in that: described installation side is provided with fixed hole, and described erection column both sides are provided with the fixed projection corresponding with fixed hole, and described fixed projection is through fixed hole.
