Description

The automobile hydraulic clutch release bearing

Technical field:

This use is novel to be the hydraulic coupling release bearing that belongs on the automobile clutch.

Background technique:

The clutch release bearing that uses on the existing big discharge capacity lorry is generally pull-type clutch release bearing, because the mechanical efficiency of the piece-rate system that it is formed wants high, transmission power is also big.But pull type clutch also exists some shortcomings: at first the operation comfortable feel of pull type clutch is not enough, and it is big that the power of stepping on clutch pedal will compare comparatively speaking, and weight ratio weight, has increased the weight of car load, repairs also cumbersome.The luxury car of big discharge capacity such as the SUV of the top grade of Sheng Chaning, pick up at home and abroad, requirement to clutch not only requires high mechanical efficiency with transmission power, but also will be particular about the operation comfortable feel of car and reduce the weight of clutch release bearing as far as possible, reduce the overall own wt of vehicle body with this.Also to consider its usability so should consider its mechanical property when selecting clutch release bearing.

The model utility content:

In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of automobile hydraulic clutch release bearing.

To achieve these goals, the utility model relates to and adopts following technological scheme:

A kind of automobile hydraulic clutch release bearing, it comprises plastic shaft bearing, oil inlet pipe, one-way valve, outlet pipe, sheath, spring, spring seat, T type sliding sleeve, Sealing, bellows, back-up ring, snap ring and release bearing part.The release bearing part is made up of outer ring, inner ring, seal ring, retainer, steel ball, self-aligning ring.Sealing is installed in the oil pocket of plastic shaft bearing.The seal ring of band skeleton is housed respectively between inner ring and the both sides, outer ring, and steel ball is fixed in the space between bearing inner race and the bearing outer ring by the seal ring of retainer and band skeleton, and self-aligning ring is installed between T type sliding sleeve and the inner ring.Oil inlet pipe is installed in filler opening on the plastic seat respectively with two jointings of relief opening with outlet pipe, and is fixedly connected with cotter pin.In order to strengthen the sealing between the assembly parts, at the assembling jointing of two pipes one O type rubber seal is housed respectively, can make the fitting tight between the product better like this, prevent that leakage of oil or oil impregnate phenomenon from appearring in product pressurized in work.Sheath is installed in two of bearing support and installs and fixes in the bolt hole, prevents that the plastic shaft bearing from twisting bolt hole brokenly when installing and fixing, and influence is installed.Spring and bellows are installed in spring seat and the outer ring recess of sliding sleeve, and dustproof effect has effectively been played in the use of dust-proof cover, avoids entering in the oil pocket impurity.Release bearing partly is installed in the place, outer ring of sliding sleeve projection.Back-up ring is installed in the inner ring of sliding sleeve projection, plays dustproof and correcting effect.The axial motion stroke of whole bearing limits by the snap ring that is installed in the bearing support inner ring top end groove.

The sealing of automobile hydraulic clutch release bearing, working life are the parts of whole bearing unit most critical, also are the technological difficulties of whole bearing unit.The utility model just solves these technological difficulties: 1. this product is mounted on the big car of discharge capacity, clutch is in motion, relative bigger of the suffered oil pressure of bearing support oil pocket, so just oil pocket is designed to one with bearing support in the design oil pocket, has so just avoided: leakage of oil or oil impregnate phenomenon appear in the oil pocket of forming because of multi-part when being subjected to big oil pressure.The incorporate design of this oil pocket is the technical characterstic and the difficult point of whole release bearing maximum, and it just has higher requirement to the selection of material and the design of processing technology.2. Sealing is to be arranged separately in the oil pocket, is two separating components with sliding sleeve, and Sealing will stick together with sliding sleeve after oil-feed in the oil pocket, and sliding sleeve drives Sealing axial motion together again, and the maximum outside diameter of Sealing is one group of interference assembling with oil pocket.Such design is in order to prevent out of plumb when motion in sliding over oil pocket, and sliding sleeve drives Sealing and produces big friction with the oil pocket wall, destroys Sealing with the sealing between the oil pocket.The installation that has also made things convenient for the simultaneously Sealing 3. movement locus of Sealing in oil pocket is to be axially reciprocating, so require the wear strength of oil sealing to reach that to-and-fro motion still keeps good sealing property later on 400,000 times in oil pocket.

Characteristics such as structure of the present utility model has mechanical efficiency to want high, and transmission power is also big, and good airproof performance is in light weight, and the operation comfortable feel is good are purchased automobile-used family good quality production are provided for vast.
