Description

Clutch pull ring

Technical Field

The utility model relates to a clutch technical field, in particular to clutch pull ring.

Background

The clutch tab is an important component in the clutch. During actual assembly, the clutch pull ring is located at the center of the diaphragm spring, and the end, inserted inwards, of the diaphragm spring is inserted between the flange of the clutch pull ring and the corresponding fixing ring. The working or separating state of the clutch is changed by changing different directions to apply force to the diaphragm spring. However, a plurality of draw hooks are arranged on the clutch pull ring in the prior art, and the lower surface of the upper section of the draw hook is communicated with a plane, so that the fixing ring is easy to slip from the draw hook in practical application. Therefore, a new clutch pull ring is needed, and through the improvement of the structure, the fixing ring is not easy to slip from the drag hook in actual use, so that the normal operation of the clutch is ensured.

It is seen that improvements and enhancements to the prior art are needed.

SUMMERY OF THE UTILITY MODEL

In view of the foregoing disadvantages of the prior art, an object of the present invention is to provide a clutch pull ring, which aims to solve the technical problem of unreasonable structure of the clutch pull ring in the prior art.

In order to achieve the purpose, the utility model adopts the following technical proposal:

a clutch pull ring comprises an annular body, wherein an annular flange is arranged at the bottom of the annular body, a plurality of notches are equidistantly formed in the annular flange along the circumferential direction, and a pull hook is arranged at each notch; each drag hook comprises a vertical section, an inclined section and barbs, the higher end of each inclined section points to the annular body, and the lower surface of each barb is provided with an arc-shaped groove; the middle part of the annular flange is upwards provided with a bulge; a plurality of fixed ring holes are formed in the annular body.

Furthermore, in the clutch pull ring, the cross section of each arc-shaped groove is semicircular.

Further, in the clutch pull ring, in a projection parallel to the plane of the annular flange, each arc-shaped groove is respectively aligned with the protrusion on the annular flange.

Further, in the clutch ring, the annular flange is provided with six notches at equal intervals along the circumferential direction.

Furthermore, in the clutch pull ring, the width of each pull hook is 5-6 mm.

Further, in the clutch pull ring, the annular body, the annular flange and each pull hook are integrally formed.

Has the advantages that: the utility model provides a clutch pull ring, including annular body, annular flange and a plurality of drag hook, compare prior art, the utility model discloses well every drag hook includes vertical section, slope section and overhead kick respectively, and the lower surface of every overhead kick is provided with the arc recess respectively for solid fixed ring can be spacing and difficult for droing in the drag hook, guarantees clutch normal operating.

Detailed Description

The utility model provides a clutch pull ring, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following combination embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 4, the present invention provides a clutch pull ring. The terms "upper", "lower", and the like are used herein based on the perspective of fig. 1 for convenience of illustration and are not intended to limit the present invention.

The clutch pull ring comprises an annular body 1, an annular flange 2 is arranged at the bottom of the annular body, a plurality of notches 200 are equidistantly arranged on the annular flange along the circumferential direction, and a drag hook 3 is arranged at each notch; each drag hook 3 comprises a vertical section 31, an inclined section 32 and barbs 33, the higher end of each inclined section 32 points to the annular body, and the lower surface of each barb 33 is provided with an arc-shaped groove 330; the middle part of the annular flange is upwards provided with a bulge; a plurality of fixed ring holes are formed in the annular body. In practice, the projection on the annular flange, i.e. the working face of the annular flange, is intended to come into contact with a diaphragm spring (not shown in the figures); the fixing rings are arranged in the pull hooks, and when the fixing rings apply force to the pull hooks, the fixing rings are in contact with the house-shaped grooves.

Preferably, the cross section of each arc-shaped groove is respectively semicircular (as shown in fig. 4), so that the limiting effect of the arc-shaped grooves on the fixing ring is further improved.

As shown in fig. 2 and 4, preferably, in a projection parallel to the plane of the annular flange (from a top view), each arc-shaped groove 330 is aligned with the protrusion 201 on the annular flange, that is, the clutch is in an operating state or a disengaged state, and the stress positions on both sides of the diaphragm spring correspond to the protrusion and the arc-shaped groove, respectively, so as to ensure that the overall stress of the diaphragm spring is balanced during the actual operation of the clutch, and avoid the inward end of the diaphragm spring from tilting.

Preferably, the annular flange is provided with six notches 200 at equal intervals along the circumferential direction, and correspondingly, six draw hooks 3 are arranged, so that even if the annular flange is processed, the fixed ring can be ensured to be uniformly contacted with the draw hooks, and the annular flange is not easy to slip off in use.

Preferably, the width of each draw hook 3 is 5-6 mm, and the draw hook is ensured to have enough mechanical strength.

Preferably, the annular body, the annular flange, and each of the draw hooks are integrally formed.

According to the above analysis, the utility model provides a clutch pull ring includes annular body, annular flange and a plurality of drag hook, compares prior art, the utility model discloses well every drag hook includes vertical section, slope section and overhead kick respectively, and the lower surface of every overhead kick is provided with the arc recess respectively for solid fixed ring can be spacing and difficult for droing in the drag hook, guarantees clutch normal operating.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
