Description
Technical field
The present utility model application belongs to vehicle transmission equipment technical field, specifically discloses a kind of tooth set.
Background technique
It is consistent that synchronizer can make the meshing part of different stalls reach speed before engagement, to reduce generation when gear shift
Between cog impact and noise, at present in the automotive industry using more and more extensive.
The inner ring of synchronizer is tooth set, and tooth set is externally provided with sliding sleeve (tooth puts on the external splines for being equipped with and engaging with sliding sleeve),
The inner surface of tooth set is equipped with the tooth engaged with output shaft, to guarantee that output shaft can take tooth set rotation to, is set to tooth to reduce
The impact force between the tooth and output shaft of inner surface is covered, odontotripsis is reduced, extends the service life of synchronizer, tooth set and output shaft
Between gap answer as small as possible, but too small gap is unfavorable for tooth set and the installation of output shaft again.
Utility model content
The purpose of this utility model is to provide being easily installed, and a kind of longer tooth set of service life.
In order to achieve the above object, the base case of the utility model are as follows:
A kind of tooth set, including ontology, body internal surface are evenly equipped with multiple raised with the circumferentially matched clamping of output shaft；Ontology
It is interior to be equipped with multiple the first connectivity slots being open towards body central, a radial hold-fast body, diameter are equipped in each first connectivity slot
To hold-fast body include with output shaft circumferentially it is matched hold tightly block and can drive hold tightly block to body central move actuator,
Hold the opening that block is slidably connected at the first connectivity slot tightly, when output shaft is inserted into ontology, actuator, which drives, holds block holding output tightly
Axis.
The working principle and beneficial effect of this base case are:
The setting of clamping protrusion facilitates output shaft and drives ontology rotation；Block and actuator are held in setting tightly, when installation, driving
Part, which drives, holds block holding output shaft rotation tightly, not only helps the stable operation of output shaft and ontology, additionally it is possible to card be effectively relieved
The abrasion (with the extension of use time, clamping protrusion can be gradually worn out under the impact of output shaft) for connecing protrusion, extends ontology
Service life.
Further, each clamping high spot is equipped with first connectivity slot, and actuator includes drive rod and transferring member, ontology
Inner sidewall be provided with the second intercommunicating pore being connected to the first connectivity slot, drive rod is slidably connected on the second intercommunicating pore, drive rod
One end connect with the first connectivity slot by pressure spring, the one end for holding block tightly is connect with the first connectivity slot by tension spring, output shaft insert
When entering ontology, drive rod is driven by the transferring member holds block tightly to body central movement.The setting energy of drive rod and transferring member
Enough relatively simple realizations, when installation, actuator, which drives, to be held block tightly and holds output shaft tightly.
Further, it is wedge shaped linkage portion that the holding block, which is in one end in the first connectivity slot,；The transferring member packet
The transmission lever for including limit base and being slidably connected on limit base, one end of transmission lever offset with the drive rod, transmission lever it is another
One end offsets with linkage portion, and drive rod is equipped with driving protrusion, and when output shaft is inserted into ontology, driving, which projects through transmission lever, to be driven
Block is held tightly to body central movement, when the realization that the setting of transferring member can be relatively simple is installed, actuator, which drives, holds block armful tightly
Tight output shaft.
Further, the quantity of the radial hold-fast body is even number, every two radial direction hold-fast body along ontology diametrically
Arrangement, it is preferable to the holding effect of output shaft.
Further, the center of two sides towards the clamping protrusion of the clamping protrusion tilts, and can effectively slow down clamping protrusion
Abrasion extends the service life of clamping protrusion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the partial enlarged view in Fig. 1 at A.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description includes: ontology 1, external splines 11, is clamped raised 12, first connectivity slot 21, embraces
Tight block 22, limit base 24, tension spring 25, pressure spring 26, linkage portion 27, drives raised 28, transmission lever 29 at drive rod 23.
As depicted in figs. 1 and 2: the outer surface of a kind of tooth set, the ontology 1 including annular, ontology 1 is equipped with external splines 11, this
1 inner surface of body is uniformly distributed, and there are six circumferentially (i.e. output shaft is circumferentially with and clamping protrusion for matched clamping protrusion 12 with output shaft
12 matched clamping groove), the center of two sides towards the clamping protrusion 12 of clamping protrusion 12 tilts.Clamping protrusion 12 is along 1 axis of ontology
To length=ontology 1 center shaft length.
First connectivity slot 21 (quantity of the first connectivity slot 21 is six) is equipped at each clamping protrusion 12, first connects
For through slot 21 towards 1 central opening of ontology, each first connectivity slot 21 is interior to be equipped with a radial hold-fast body.Radial hold-fast body includes
It holds block 22 tightly and can drive and hold the actuator mobile to 1 center of ontology of block 22 tightly, hold inner surface and the output shaft week of block 22 tightly
To matching, the opening that block 22 is slidably connected at the first connectivity slot 21 is held tightly.Hold block 22 is in the first connectivity slot 21 one tightly
End is wedge shaped linkage portion 27.Actuator includes drive rod 23, limit base 24 and the transmitting being slidably connected on limit base 24
Bar 29 (limit base 24 and transmission lever 29 be transferring member), the inner sidewall of ontology 1 are provided with the second company be connected to the first connectivity slot 21
Through-hole, drive rod 23 are slidably connected on the second intercommunicating pore, and one end of drive rod 23 is connected with the first connectivity slot 21 by pressure spring 26
It connects, the one end for holding block 22 tightly is connect with the first connectivity slot 21 by tension spring 25.One end of transmission lever 29 offsets with drive rod 23, passes
The other end and linkage portion 27 for passing bar 29 offset, and drive rod 23 is equipped with driving protrusion 28.
When installation, when output shaft is inserted into ontology 1, drive rod 23 is slided into the first connectivity slot 21, the drive on drive rod 23
It is mobile to block 22 is held tightly that dynamic protrusion 28 drives transmission lever 29, thus realize transmission lever 29 driven by linkage portion 27 hold tightly block 22 to
1 center of ontology is mobile, holds block 22 tightly and holds output shaft tightly.
Above-described is only the embodiments of the present invention, and the common sense such as well known specific structure and characteristic are herein in scheme
It does not describe excessively.It should be pointed out that for those skilled in the art, in the premise for not departing from the utility model structure
Under, several modifications and improvements can also be made, these also should be considered as the protection scope of the utility model, these all will not influence
The effect and patent practicability that the utility model is implemented.
