Description
Technical field
The utility model relates to a kind of light-duty pull type clutch release bearing, belongs to the clutch release bearing technical field.
Background technique
Clutch is between motor and gearbox, clutch is when transferring power and cut-out power, its operating mechanism is stirred release sleeve by disengaging yoke, release sleeve promotion declutch shaft is made to be moved axially, the push-press separation lever is around its spot wobble, thereby drive separation pull bar makes platen engage with driven disc or separates.The error of the pipe spreader and the clutch gyration center of gearbox be can compensate when working simultaneously automatically, wearing and tearing and noise between part effectively reduced.For medium-sized or heavy Motor Vehicle, because the driving torque of power is bigger, and the pull type clutch release bearing is because fulcrum is outer, have in the light characteristics of same Separating force lower-pilot, so for the more and more pull type clutch release bearings that adopt of the clutch of medium-sized and heavy vehicle.But present disclosed pull type clutch release bearing, as shown in Figure 1, constitute by bearing inner race 1, bearing outer ring 2, retainer 5, rolling element 3, seal ring 6 and release sleeve 7 and outer cover 4, but bearing outer ring is connected by outer cover with release sleeve, therefore the connecting end of release sleeve must be positioned at the periphery of bearing outer ring, because processing accessories is more, installation procedure is many on the one hand, also make the volume of clutch release bearing bigger, the deadweight of release bearing is heavier; On the other hand because the shift fork seat is arranged on the side of release sleeve away from release bearing, the axial dimension of whole clutch release bearing is longer, disengaging yoke drives release bearing and moves axially by stirring shift fork seat on the release sleeve, and the working stability of clutch release bearing is not high.
Summary of the invention
It is little that the purpose of this utility model provides a kind of volume, in light weight, the light-duty pull type clutch release bearing assembly of good operating stability.
The utility model is that the technological scheme that achieves the above object is: a kind of light-duty pull type clutch release bearing, comprise bearing inner race, bearing outer ring, retainer and rolling element and release sleeve, rolling element is installed in the pocket hole of retainer and is connected with bearing outer ring with bearing inner race respectively, between the outside of bearing outer ring and the bearing inner race seal ring is installed, it is characterized in that: described bearing inner race one end extends bearing outer ring, the other end of bearing inner race is positioned at bearing outer ring, T-shaped release sleeve is arranged in the bearing inner race, and the interior edge face of the T shape head of release sleeve is pressed in the end face of bearing outer ring, the exterior edge face of the T shape head of release sleeve is connected with bearing outer ring by back-up ring, and bearing outer ring is provided with the shift fork seat.
Wherein: the outer end of described bearing inner race is provided with annular lock groove.
Described bearing outer ring is provided with symmetry and protruding shift fork seat more than two.
A T shape exterior edge face of described release sleeve is positioned within the end face of bearing outer ring or with the bearing outer ring end face and maintains an equal level.
The utility model is connected by back-up ring release sleeve with bearing outer ring, release sleeve is arranged in bearing inner race and the bearing outer ring, dwindled the axial dimension of clutch release bearing significantly, because the shift fork seat is to be provided with on the bearing outer ring, directly stir release bearing by disengaging yoke, so improved the working stability of clutch release bearing.The utility model is arranged on release sleeve on bearing inner race and the bearing outer ring, therefore makes bearing outer ring also be available as bearing support and uses, and can improve the wear resistance and the impact resistance of release bearing.The utility model has been owing to improved the structure of release bearing, not only reduces number of spare parts use manufacturing procedure, and reduced the size and the volume of release sleeve, conducts oneself with dignity and volume so can alleviate release bearing.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the structural representation of former pull type clutch release bearing.
Fig. 2 is the structural representation of the light-duty pull type clutch release bearing of the utility model.
Wherein: 1-bearing inner race, 11-annular lock groove, 2-bearing outer ring, 21-shift fork seat, 22-bulge loop, 3-rolling element, 4-outer cover, 5-retainer, 6-seal ring, 7-release sleeve, 8-back-up ring.
Embodiment
See shown in Figure 2, light-duty pull type clutch release bearing of the present utility model, comprise bearing inner race 1, bearing outer ring 2, retainer 5 and rolling element 3 and release sleeve 7, rolling element 3 is installed in the pocket hole of retainer 5, rolling element 3 is connected with bearing outer ring 2 with bearing inner race 1 respectively, rolling element 3 can be rotated in the raceway of bearing inner race 1 and bearing outer ring 2, between the outside of bearing outer ring 2 and the bearing inner race 1 seal ring 6 is installed, and to satisfy the sealability of release bearing, see shown in Figure 2, bearing inner race 1-end of the present utility model extends bearing outer ring 2, the outer end of bearing inner race 1 is provided with annular lock groove, as the unidirectional latch hook that separates draw ring is installed, the extension of bearing inner race 1 is for being multidiameter shaft, the other end of bearing inner race 1 is positioned at bearing outer ring 2, T-shaped release sleeve 7 is arranged in the bearing inner race 1, the interior edge face of the T shape head of release sleeve 7 is pressed in the end face of bearing outer ring 2, the exterior edge face of the T shape head of release sleeve 7 is connected with bearing outer ring 2 by back-up ring 8, release sleeve 7 is connected with release bearing, the utility model is convenient to install, the T shape interior edge face that release sleeve 7 contacts with bearing outer ring 2 is a bulge loop face 22, and the exterior edge face of release sleeve 7T shape head is positioned at the end face inboard of bearing outer ring 2 or maintains an equal level with bearing outer ring 2 end faces, and bearing outer ring 2 is provided with shift fork seat 21, be preferably in bearing outer ring 2 and be provided with symmetry and protruding shift fork seat 21 more than two, disengaging yoke is directly stirred release bearing, and improves the working stability of release bearing.The utility model bearing outer ring 2 can be used as bearing support, after bearing outer ring 2 is heat-treated with special material, makes release bearing have wear-resisting property preferably.
When the clutch proper functioning, under the elastic force effect of diaphragm spring, the master of clutch, passive wearing piece are engaged; When disengaging yoke during, directly drive release bearing and outwards move, and the separation draw ring that is connected on the bearing inner race 1 also moves laterally along main shaft to clutch outside shifting shaft bearing outer-ring 2, then diaphragm spring also moves thereupon, at this moment, the master of clutch, passive wearing piece separate, and cut off power output.
