Description

Seal Spring Plate for Coupling Disassembly Bearing {SEALING SPRING PLATE FOR COUPLING SEPARATING BEARING}

The dismantling bearing is used in the dismantling device of the vehicle to operate the contact separation coupling disposed between the internal combustion engine and the gearwheel transmission. The configuration of the dismantling bearing, which is typically composed of inclined shoulder bearings, includes a rotatably disposed bearing ring and a rotatable peripheral bearing ring, wherein the roller body is guided between the two bearing rings. The rotatably disposed bearing ring is provided with a radially aligned arm or flange, which arm or flange is rotatably coupled with an axially movable part of the dismantling device with the dismounting bearing mounted. Non-positively positionally supporting the arm is achieved by a spring member inserted between the axially movable part of the dismantling device and the arm of the bearing ring. The bearing for disassembly is also provided with a sealing member that effectively prevents all kinds of impurities from flowing into the roller bearing.

The bearing for disassembly of known construction is fixed to the part of the dismantling device by means of a leaf spring. In particular, a separate sealing plate which is fixed non-positively to the bearing ring is used to seal the roller bearing inner space.

US 4,637,506 shows a bearing for dismantling in this manner in a different embodiment. Common to all embodiments is an externally rotatable outer bearing ring in which the radially inwardly facing arm of the bearing is supported by a flange of an axially movable part of the dismantling device. At one end on the roller body side at the arm of the outer bearing ring is supported an L-shaped spring member, the other end of which is locked to an axially movable attachment of the dismantling device. A sealing member is fixed in the region of the arm among the inner surfaces of the rotatable outer bearing rings, the free end of which is guided to the rotatable inner bearing ring. Known configurations of dismantling bearings require a number of assembly steps for the leaf springs and sealing members. In addition to the risk of error assembly of the parts, the dismantling bearings of this type have a large part perimeter which acts as a disadvantage.

It is an object of the present invention, starting from the deficiencies of known solutions, to provide a dismantling bearing that is optimal for parts while reducing costs.

The above object is achieved by a bearing for disassembly having a sealing spring plate according to the invention. According to the above solution, the sealing plate is combined with a leaf spring which together forms one part. The inner region of the sealing spring plate according to the invention forms a leaf spring which is radially aligned with the outer surface and which is connected with a section formed as a sealing member. The inner region of the sealing spring plate according to the invention, also referred to as the spring member, is locked at the free end in the axially movable part of the dismantling device. The sealing spring plate is supported non-positively on the arm of the bearing ring which is axially displaced relative to the part and is arranged in a rotatable manner. The radially outer region of the sealing spring plate forms a sealing member, in which case the free end is guided to the inner contour of the peripheral bearing ring of the bearing for dismantling while maintaining the ring-shaped gap.

The sealing spring plate according to the invention reduces the assembly cost and the circumference of the part due to the integral structure, which leads to significant cost savings. In addition, the shape according to the invention of the sealing spring plate facilitates the automatic assembly of the bearing for dismantling.

Further preferred embodiments described below are the subject of the dependent claims 2 to 9.

One preferred embodiment of the present invention includes a support member, by which the bearing for dismantling is fixed to an axially movable component of the dismantling device. The support member, also referred to as the intermediate member, is preferably formed such that the support member surrounds, for example, at the end face a ring piston movable in the axial direction of the dismantling device, and is positively fixed to the ring piston. A section of the radially displaced u-shaped support member is used for receiving the arm of the bearing ring which is not rotatably disposed and for supporting the inner section of the sealing spring plate according to the invention.

It is proposed that the shape of the sealing spring plate extends from the support surface in the bearing ring in which the plate is rotatably arranged to the free end. That is, it is preferable that it is formed in the form of protrusions. At the outer surface the sealing spring plate forms an axially displaced and radially aligned section with respect to the support surface. In the state where the sealing spring plate according to the invention is fitted, the radially running section is guided to the inner contour of the peripheral bearing ring while maintaining the ring gap.

The inner surface of the sealing spring plate may also be provided with a bent, cylindrically aligned accessory. An accessory of this type is suitable for centrally placing the sealing spring plate on the support member and for positioning it in the board of the U-shaped receptacle of the support member.

The invention also includes a sealing spring plate in which the radially running outer section is edged to form an arm at a right angle at the end face, preferably in the direction of the roller body. By means of this measure, preferably, an extended sealing gap can be realized, and on the one hand, the risk of lubricating material from the dismantling bearing can be prevented by the extended sealing gap, and on the other hand, impurities can be removed. It can effectively prevent the inflow inside.

The preferred formation of the sealing spring plate suggests that the inner regions formed as spring members are provided with slots arranged radially and arranged around each other. In this case, the slots can be formed in different structural shapes. The slot can affect the modulus of elasticity and the rigidity of the spring member.

The size of the ring-shaped gap set between the outer contour of the plate and the inner wall of the circumferential bearing ring with the sealing spring plate fitted is preferably ≥ 0.1 mm. The ring-shaped gap then depends in particular on the movement path of the dismantling bearing during self-centering.

Spring steel is particularly suitable for the sealing spring plate according to the invention. The sealing spring plate formed in the non-cutting manner has a thickness of> 0.2 mm.
