Description

A kind of separating mechanism with retaining ring

Technical field

The utility model belongs to automobile clutch field, especially a kind of separating mechanism with retaining ring.

Background technique

5J100T speed changer is mainly used for bus, and clutch use is more frequent, and separating mechanism is close to engine, herein Operating temperature is higher.Needle bearing has magnitude of interference with clutch housing diametrical direction in assembly, but due to expanding with heat and contract with cold, Magnitude of interference reduces when work, or even generates gap, and needle bearing is caused to fall off from clutch housing, causes to separate clamping stagnation or have Step sense, operation is not smooth, and failure rate is high.Existing separating mechanism increases circlip in needle bearing two sides, to prevent from rolling Needle bearing falls off.But circlip needs operative employee to continue to exert oneself with Circlip tongs, breaks circlip into two with one's hands, pass through from shaft end in assembly, on one side Assembling jump ring will also fill disengaging yoke axis on one side, and assembly efficiency is low.

Utility model content

The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of separating mechanism with retaining ring.

In order to achieve the above objectives, the utility model is achieved using following technical scheme:

A kind of separating mechanism with retaining ring, including clutch housing, bell housing body is interior to be equipped with needle bearing, needle bearing Disengaging yoke axis, the fluting for being circumferentially with construction opening retaining ring of disengaging yoke axis are equipped in hole, the fluting is located at separation and dials The side of fork shaft.

Further, the most inner side extended distance of the split washer is less than the groover rot diameter of disengaging yoke axis fluting.

Further, there are two split washers for installation in the slot.

Further, the opening of described two split washers is symmetrical about the center of circle of the vertical cross-section of place axis.

Further, the split washer is c-type.

Further, needle bearing has magnitude of interference in the diametrical direction with clutch housing.

Compared with prior art, the utility model has the following beneficial effects:

Due to the presence of split washer, it can prevent needle bearing from falling off out of bell housing body；On the other hand, opening In the presence of retaining ring can be directly loadable into from the side of axis, it is not necessary to pass through axis, promote assembly efficiency；The separating mechanism energy with retaining ring Enough overcome falling off for needle bearing to cause to separate clamping stagnation or have step sense, operates not smooth, the high defect of failure rate, and It is easy for installation.

Detailed description of the invention

Fig. 1 is the installation diagram of the separating mechanism with retaining ring of the utility model；

Fig. 2 is the structure chart of the separating mechanism guide ring with retaining ring of the utility model.

Wherein: 1- clutch housing；2- needle bearing；3- disengaging yoke axis；4- split washer.

Specific embodiment

In order to make those skilled in the art better understand the scheme of the utility model, below in conjunction with the utility model reality The attached drawing in example is applied, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only the embodiment of the utility model a part, instead of all the embodiments.Based on the reality in the utility model Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts is all answered When the range for belonging to the utility model protection.

It should be noted that the specification and claims of the utility model and term " first " in above-mentioned attached drawing, " second " etc. is to be used to distinguish similar objects, without being used to describe a particular order or precedence order.It should be understood that in this way The data used are interchangeable under appropriate circumstances, so that the embodiments of the present invention described herein can be in addition at this In illustrate or description those of other than sequence implement.In addition, term " includes " and " having " and their any deformation, meaning Figure be to cover it is non-exclusive include, for example, containing the process, method, system, product or equipment of a series of steps or units Those of be not necessarily limited to be clearly listed step or unit, but may include be not clearly listed or for these processes, The intrinsic other step or units of method, product or equipment.

The utility model is described in further detail with reference to the accompanying drawing:

Referring to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 is respectively the installation diagram and this reality of the separating mechanism with retaining ring of the utility model With the structure chart of the novel separating mechanism guide ring with retaining ring；As can be seen that needle bearing 2 in clutch housing 1, divides From the bearing hole that shift fork axle 3 passes through needle bearing 2, retaining ring 4 is located in the slot of disengaging yoke axis 3, and the slot position is in needle bearing 2 Side, for preventing falling off for needle bearing 2.

For the ease of the installation of retaining ring, retaining ring 4 is set as split washer, the most inner side extended distance of split washer, which is less than, to be divided Groover rot diameter from shift fork axle fluting, retaining ring 4 can be directly directly loadable into from the side of disengaging yoke axis 3, it is not necessary to pass through axis Assembly, and be unlikely to circlip looseness and fall off, improve assembly efficiency.

It, in this way can be to greatest extent when the opening of two split washers is symmetrical about the center of circle of the vertical cross-section of place axis Prevent the opening of split washer to be overlapped in the axial direction of disengaging yoke axis, cause 2 side of needle bearing to be in contact with opening, The phenomenon that stopping needle bearing 2 to fall off is not had.

The utility model provides a kind of specific split washer, is c-type.

A kind of mounting means of the separating mechanism with retaining ring, comprising the following steps:

It 1) will be in 2 clutches shell 1 of two pieces needle bearing；

2) disengaging yoke axis 3 is installed, disengaging yoke axis 3 is made to pass through the bearing hole of needle bearing 2

3) two pieces split washer 4 is attached in the slot of disengaging yoke axis 3, and the slot position of disengaging yoke axis 3 is in the side of needle bearing 2 Face.

It by the opening of split washer 4, can be directly directly loadable into from the side of disengaging yoke axis 3, it is not necessary to pass through axis and fill Match, to prevent needle bearing 2 from falling off, improves assembly efficiency.

The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality Within protection scope with novel claims.
