The risk for being bent and being generated burr during assembling clutch release system is also eliminated at the first clamping piece 711.
As shown in figure 3, the present invention also provides the clutch release systems of the retaining ring 7 including Fig. 2.The clutch separation
System further includes leaf spring 6 and clutch release bearing, and the inner ring radial component 22 of leaf spring 6 and clutch release bearing is in axial A
On be connected in the first elastic card socket part first clamping piece 711 and interconnecting piece 73 between.
As shown in figure 3, clutch release bearing include outer ring 1, inner ring 2, ball 3, the retainer 4 for keeping ball 3 and
Sealing element for the gap between sealed outer ring 1 and inner ring 2.Outer ring 1 has the outer ring axial part that A extends generally along an axial
Points 11 and extend from axial one end (left-hand end in Fig. 3) of outer ring axial component 11 along radial R towards radially inner side
Outer ring radial component 12；Inner ring 2 has the inner ring axial component 21 that A extends generally along an axial and from inner ring axial component 21
The inner ring radial component 22 that extends along radial R towards radially inner side of axial one end (left-hand end in Fig. 3).Wherein, outer ring
Axial component 11 is oppositely arranged on radial R at interval with inner ring axial component 21, and outer ring radial component 12 and inner ring are radial
Part 22 is oppositely arranged at interval on axial A, and the radially inner side end of inner ring radial component 22 is than outer ring radial component
Radially inner side is more leaned at 12 radially inner side end.The rolling that ball 3 is formed between outer ring axial component 11 and inner ring axial component 21
In road, ball 3 is held in the raceway by retainer 4.
In addition, retaining ring 7 is integrally located at the radially inner side of clutch release bearing and retaining ring 7 passes through multiple first bullets
Property clamping portion first clamping piece 711 and interconnecting piece 73 on axial A to the inner ring radial part of leaf spring 6 and clutch release bearing
22 are divided to be limited.More specifically, the free end of the first clamping piece 711 of retaining ring 7 is connected to the radially inner side end of leaf spring 6
Portion, the radial outside end abutment of leaf spring 6 is in inner ring radial component 22, and inner ring radial component 22 is resisted against interconnecting piece 73, in this way
It is achieved that the first clamping piece 711 and interconnecting piece 73 that leaf spring 6 and inner ring radial component 22 are held on to the first elastic card socket part
Between.In addition, preloading ring 5, from the right side in Fig. 3 to be installed on the radially inner side of inner ring axial component 21 pre- to apply to inner ring 2
On-load pressure.In the state of being completed shown in fig. 3, the first cylindrical portion 71 of inner ring radial component 22 and retaining ring 7
Peripheral wall there is scheduled interval radially, this ensure that clutch release bearing can play the role of Self-aligning.
Illustrate leaf spring 6 and the clutch separation in clutch release system according to the present invention below according to Fig. 4 a to Fig. 4 c
The step of inner ring radial component 22 of bearing is installed on retaining ring 7 shown in Fig. 2.Firstly, as shown in fig. 4 a, by clutch separation
Bearing (inner ring radial component 22) is set in the radial outside of the first cylindrical portion 71 of retaining ring 7 and is resisted against interconnecting piece 73, will
Leaf spring 6 is placed in the position with the opposite side (left side in Fig. 4 a) of 72 place side of the second cylindrical portion of the first cylindrical portion 71；Then,
As shown in Figure 4 b, so that leaf spring 6 is set in the radial outside of the first cylindrical portion 71 and move closer to clutch release shaft on axial A
The inner ring radial component 22 held, in this process, when first clamping piece 711 of the leaf spring 6 by the first clamping portion, the first card
Contact pin 711 generates the flexible deformation towards radially inner side on radial R and enables leaf spring 6 on axial A successfully by the
One clamping piece 711；Finally, as illustrated in fig. 4 c, leaf spring 6 successfully crosses the first clamping piece 711 on axial A, thus leaf spring 6
Radial outside end (part at the close radial outside end of leaf spring 6) is connected to inner ring radial component 22, and the first clamping piece 711 exists
The radially inner side end (part at the close radially inner side end of leaf spring 6) of leaf spring 6 is restored to the original state and is connected on radial R, this makes
It obtains and compresses on 6 axial direction A of leaf spring to generate the spring force on axial A.Finally, each component is in end-state shown in Fig. 3.
It, can be easily by the inner ring of leaf spring 6 and clutch release bearing radial direction by using above-mentioned installation steps
Part 22 is installed on retaining ring 7.
Although having carried out detailed elaboration to a specific embodiment of the invention above, also need to carry out following say
It is bright：
Although 1, illustrating that the quantity of the first clamping portion is 6 in above specific embodiment, the present invention is not
It is limited to this, can be set according to actual needs any number of first clamping portion.
2, the structure of the first clamping portion be also not necessarily limited to more than specific embodiment in the structure that illustrates, as long as can be realized
Leaf spring 6 and inner ring radial component 22 are limited with the cooperation of interconnecting piece 73 on axial A.
Although 3, not clearly stated in above specific embodiment it should be appreciated that holding according to the present invention
Ring is preferably made of metal material.
By using above-mentioned technical proposal, in advance the peripheral wall of retaining ring formed multiple first elastic card socket parts so as to
So that leaf spring is in scheduled position and provides scheduled spring force, and then it ensure that the Self-aligning function of clutch release bearing
Energy；In addition, eliminating in the prior art due to being pre-formed multiple first elastic card socket parts in an assembling process to holding
Ring is bent and is generated the risk of burr；Also to include this further, since being pre-formed multiple first elastic card socket parts
The assembling process of the clutch release system of the retaining ring of invention simplifies.
In addition, protection scope of the present invention is not limited to the specific embodiment of above-mentioned specific embodiment, as long as but can
The combination for meeting the technical characteristic of claim of the invention is just fallen within protection scope of the present invention.
