Description
Technical field
The invention belongs to auto parts machinery, the aligning-type Hydraulic Pressure Declutched Bearing Assembly that a kind of inner ring rotates.
Background technology
Existing Hydraulic Pressure Declutched Bearing Assembly is as it is shown in figure 1, be that the outer ring of release bearing rotates with clutch compressing disc.On the premise of other factors inconvenience, identical clutch compressing disc rotating speed, the contact cycle-index many about 30% of rolling element when the contact cycle ratio bearing inner race of rolling element rotates when bearing outer ring rotates, say, that short about the 20-30% of theoretical life-span of the bearing that the bearing that outer ring rotates rotates than inner ring.
It addition, clutch compressing disc contacts with the outer face of bearing outer ring, easily rubbish is pushed in the gap between inner ring and outer ring, bring in bearing element raceway groove by the centrifugal force of outer ring, serious infringement bearing element performance.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome that the existing Hydraulic Pressure Declutched Bearing Assembly life-span is short, roll in raceway groove the defect easily entering dust, it is provided that a kind of can effectively extend bearing life, reduce dust and enter and roll the aligning-type Hydraulic Pressure Declutched Bearing Assembly that the inner ring of raceway groove rotates.
For reaching above-mentioned purpose, the aligning-type Hydraulic Pressure Declutched Bearing Assembly that the inner ring of the present invention rotates, including hydraulic jack and release bearing, described hydraulic jack includes outer casing wall, interior casing wall, plunger, described release bearing includes outer ring, inner ring, rolling element, retainer, sealing ring, it is characterized in that: on described plunger, assemble a sleeve body, described release bearing can radially being assemblied on described sleeve body of aligning, the outer face of described inner ring is set to the rubbing surface for contacting with clutch compressing disc spring leaf.
As optimization technique means: set the first loading end on described plunger, a first annular resilient part being supported on described plunger borrows the elastic force of self by described sleeve body pressure holding on the first described loading end.
As optimization technique means: maintain radial clearance between described sleeve body and plunger.
As optimization technique means: the contact site of described sleeve body and the first loading end passes through mating spherical surfaces.
As optimization technique means: the axis of described sleeve body borrows described sphere to have the swing angle of 0.5 °-10 ° relative to the axis of described plunger.
As optimization technique means: the inner of described outer ring is extended with end wall, maintains radial clearance between described end wall and sleeve body.
As optimization technique means: the radial clearance between described end wall and sleeve body is 0.2-2.5mm.
