Description
Technical field
The invention belongs to automobile clutch technical field of sealing technology, and in particular to a kind of self-aligning separable bearing of clutch is total
Into.
Background technology
Clutch is that a kind of conventional control engine power system of existing manual-gear vehicle is switched on or switched off with speed changer
A kind of important component.The output shaft of clutch is exactly the input shaft of gearbox.In vehicle traveling process, driver can basis
Need to tip into or out clutch pedal, actuator drives clutch shifter, by clutch release bearing to clutch pressure
Disk applies external force, so that the friction plate of clutch is separated from each other or combined, because clutch is rotation status at work,
And clutch shifter is not rotation status, so, clutch release bearing total performance is by non-rotary pressure, is applied to rotation
Clutch compressing disc on a transition apparatus, if damage, the failure of clutch will be caused, to vehicle traveling cause danger.
Current clutch release bearing assembly includes housing, bearing inner race, rolling element, bearing outer ring, is arranged on mostly
Bearing both ends closure and case, in order to ensure that release bearing pivot overlaps with the pivot of clutch shaft, present axle
The internal diameter for holding inner ring uses the diameter for the axle journal being more than on housing, in favor of the automatic aligning of bearing, such bearing inner race and shell
Certain gap is left between body axle journal, and this gap is open type in the course of the work, it is easy into dust, enter
Dust in bearing, the normal work of bearing can be influenceed, increase the abrasion of bearing, meanwhile, dust and the lubrication for being injected into bearing
Fat combines, and forms block, when bearing rotates at a high speed, is easy to damage the closure of bearing end so that bearing makes
With the lost of life, the failure of clutch is in turn resulted in.
In order to solve the above technical problems, technical staff set between the bearing inner race and housing axle journal of release bearing it is dust-proof
Sealing device, it is such a dust-proof such as the Chinese invention patent application that this Shen people's identified patent applications number are 201310525562.3
Sealing device is compressed between bearing inner race and housing axle journal, while be must also be ensured that the rotation of bearing and ensured separation shaft
The automatic aligning held, ensure the gap between bearing inner race and housing axle journal, and the gap is not stop to change, this structure is more
During secondary use, proved through test of many times, if contact band of the sealing lip of dust-proof sealing device with bearing inner race is big,
Dust seal abrasion is very fast in release bearing rotary course, and service life is short, and contacts with small, does not reach dust seal
Purpose.Moreover, the shaft shoulder end face of housing directly contacts with release bearing end face, there is no sealing device between both ends of the surface, dust and
Impurity can enter the gap between bearing inner race and housing axle journal along the gap between both ends of the surface, influence the normal work of bearing,
Influence the service life of release bearing.
The content of the invention
In summary, in order to overcome the shortcomings of prior art problem, the invention provides a kind of separation of self-aligning separable
Bearing assembly, it is to set sealing device in the side of the close housing shaft shoulder of the bearing inner race of release bearing, while in housing
Ring shaped contact band is set on the end face of the shaft shoulder, and the ring shaped contact band is ring-shaped groove, the sealing lip insertion ring shape of sealing device
In groove, form ditch and return sealing structure, so as to prevent dust and impurity between housing shaft shoulder end face and release bearing end face
Gap enters, meanwhile, open-work is set in ring-shaped groove, in release bearing rotation process, dust and impurity exclude from open-work,
Prevent the accumulation of dust and impurity.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of self-aligning separable bearing of clutch assembly, including housing, bearing inner race, rolling element, bearing outer ring, bearing are close
Capping and case, the axle journal of housing are inserted into bearing inner race, bearing inner race, bearing outer ring, rolling element and bearing seal cover group
Into rolling bearing structure, case is covered on outside bearing outer ring, wherein：The side of the close housing shaft shoulder of described bearing inner race is set
There is sealing ring, the sealing ring includes ring skeleton and sealing lip, ring skeleton are fixedly connected with bearing inner race, and sealing lip is consolidated
It is scheduled on ring skeleton, is provided with ring shaped contact band on the end face of the close bearing inner race of the shaft shoulder of described housing, the annular
Contact band is the ring-shaped groove that sets on the end face of the shaft shoulder of housing, in the sealing lip insertion ring shape groove of sealing ring.
Further, the width of described ring shaped contact band is 1.5 ~ 3.5mm.
Further, the ring skeleton of described sealing ring is welded and fixed or vulcanized and is fixed on bearing inner race.
Further, at least one open-work is provided with the inner bottom surface of described ring shaped contact band, the open-work penetrates housing
The shaft shoulder, and open-work is located at the inner side of the sealing lip of sealing ring.
Beneficial effects of the present invention are：
1st, the present invention is that sealing device is set in the side of the close housing shaft shoulder of the bearing inner race of release bearing, while
Ring shaped contact band is set on housing shaft shoulder end face, and the ring shaped contact band is ring-shaped groove, the sealing lip insertion ring of sealing device
In shape groove, form ditch and return sealing structure, ditch returns the sealing effectiveness of sealing structure apparently higher than the sealing of common crush seal circle
Effect, so as to effectively by the end face seal of the end face of release bearing and the shaft shoulder of housing, effectively prevent dust and miscellaneous
Gap between bearing inner race and housing axle journal that matter enters release bearing from the gap between both ends of the surface, so as to ensure bearing
Service life, ensure the safe and stable operation of automobile clutch.
2nd, the present invention sets in ring-shaped groove and penetrates the open-work of the housing shaft shoulder, into the end face of release bearing and housing
Dust and impurity between the end face of the shaft shoulder, after the stop by sealing ring, it can accumulate in sealed groove, in release bearing
In rotation process, sealing ring rotates with release bearing, so that the dust and impurity that accumulate in sealed groove rotate, by saturating
Kong Shi, dust and impurity can be discharged in time from open-work, and so as to effectively prevent the deposition of dust and impurity, open-work plays dust discharge passage
Effect.
3rd, the width of ring shaped contact band of the invention is 1.5 ~ 3.5mm, and the ring shaped contact band is the end face of the shaft shoulder of housing
The ring-shaped groove of upper setting, the ring-shaped groove can be formed by grinding, and its depth can be with smaller, as long as itself and housing
Size difference be present in shaft shoulder end face.While sealing effectiveness is ensured, additionally it is possible to the effective setting for avoiding sealed groove
Destruction to the shaft shoulder intensity of housing, ensure the safe and stable operation of clutch.
