Abstract
The utility model discloses a hydraulic operating cylinder of a automobile clutch, which comprises a spring, a piston, a leather cup, a push rod and a dust shield which are sequentially positioned in a cylinder body along the axial direction, wherein, an oil entrance is arranged on one side of the cylinder body. The utility model is characterized in that a lining made of aluminum alloy material is positioned between the piston and the cylinder body; the lining is fixed on the inner wall of the cylinder body through a clasp, and sealed with the cylinder body through two O-shaped rings on the two ends thereof; the latter half part of the piston is tightly contacted with the inner wall of the lining in a sliding way. The oil entrance is changed to adopt a quick joint; the joint section is sequentially provided with a seal ring and a guard ring from inside to outside. The utility model solves the seal problem in the hydraulic operating cylinder of the automobile clutch, and has the advantages of convenient installation and use, good sealing, long service life, etc.
Description
Technical field
The utility model relates to a kind of hydraulic work cylinder of automobile clutch.
Background technique
At present, the structure of known automobile clutch hydraulic work cylinder is generally: at the cylinder body interior edge face, and axial successively mounting spring, piston, push rod and dust-proof cover; The head of piston inserts among the spring, and its latter half part slides with inboard wall of cylinder block and closely contacts, and the centre of its contact segment is provided with a groove, and the inside is equipped with leather cup, is further sealed; Push rod exposes cylinder part and seals with dust-proof cover, enters cylinder body to prevent dust.One side of cylinder body is provided with an oil inlet hole, all adopts inipple usually.Above-mentioned piston, leather cup, cylinder body are formed a sealed space, and the inside is full of brake oil, and the change of oil pressure causes the change of this spatial volume, move thereby promote piston, promote clutch separation by push rod again.
Because the housing of clutch release slave cylinder is the plastics manufacturing, its internal surface can't reach the bright and clean level of gold machining part, and in use because the to-and-fro motion of piston, easy deformation and cause the sealability variation, make and the thrust deficiency of push rod cause the automobile clutch job insecurity.Simultaneously, adopt inipple to be connected between the filler opening of prior art clutch release slave cylinder and the oil pipe, when housing was plastics, this structure was used, makes inconvenient, and sealing is also poor, easy leakage of oil.
Summary of the invention
Poor as the automobile clutch hydraulic work cylinder sealing of housing in order to solve above-mentioned prior art with plastics, job insecurity, and deficiencies such as the filler opening sealing is poor, installation inconvenience, the purpose of this utility model is to provide a kind of automobile clutch hydraulic work cylinder.Utilize the utility model, not only reach the requirement of high sealing, stable operation, and prolonged the working life of product.
In order to reach the foregoing invention purpose, the utility model is that the technological scheme that its technical problem of solution is adopted provides a kind of automobile clutch hydraulic work cylinder, and this device comprises: spring, piston, leather cup, push rod, the dust-proof cover axially installed successively in cylinder body the inner; One side of cylinder body is provided with oil inlet hole.According to the utility model, this device also comprises: described inboard wall of cylinder block is with also being provided with a lining between the piston latter half part, this lining adopts the manufacturing of aluminum alloy material, and its length equals the stroke that the piston latter half part slides.Described lining is fixed in the inwall of cylinder body by snap ring, and two O type circles by two are with the cylinder body static seal.The latter half part of piston is with the closely contact of inwall slip of lining.Described oil inlet hole is rapid pipe joint, and joint area is disposed with seal ring and protective ring from inside to outside.
A kind of automobile clutch hydraulic work of the utility model cylinder is owing to take above-mentioned technological scheme, parts such as lining and seal ring have been increased, motive sealing between leather cup and the plastic cylinder is changed into more the static seal between the lining and cylinder body reliably, between further play seal action by two O type circles.Simultaneously, oil inlet hole changes rapid pipe joint into by original inipple, therefore, has solved the sealing problem of prior art plastics as the automobile clutch hydraulic work cylinder of housing, has obtained beneficial effects such as easy to install, good airproof performance, long service life.
Description of drawings
Fig. 1 is a plan view, the structure of a kind of automobile clutch hydraulic work of expression the utility model cylinder;
Fig. 2 is the left view of a kind of automobile clutch hydraulic work of the utility model cylinder.
Embodiment
Below in conjunction with description of drawings preferred embodiment of the present utility model.
Fig. 1 is a plan view, and Fig. 2 is a left view, the structure of a kind of automobile clutch hydraulic work of expression the utility model cylinder; Shown in the embodiment of Fig. 1 and Fig. 2, this device comprises: push rod 1, dust-proof cover 2, snap ring 3, cylinder body 4, lining 5, piston 6, leather cup 7, O type circle 8, spring 9, seal ring 10, protective ring 11, technology plug 12.Its configuration annexation is as follows:
In sum, the utility model is with the difference of prior art plastics as the automobile clutch hydraulic work cylinder of housing: cylinder body 4 inwalls are with having increased a lining 5 between the piston 6 sliding strokes part, lining 5 is fixed in the inwall of cylinder body 4 by snap ring 3, and two O type circles 8 by two are with the cylinder body static seal.The latter half part of piston 6 is not that the inwall with cylinder body 4 directly contacts, but with the tight sliding contact of inwall of lining 5, has therefore improved the airtight precision of surface of contact.Lining 5 adopts aluminum alloy material or other metallic material to make, and any surface finish is durable.Above-mentioned oil inlet hole changes rapid pipe joint into by original inipple, and joint area is equipped with seal ring 10, protective ring 11 and technology plug 12 from inside to outside successively.
Further working principle of the present utility model is described below.
Above-mentioned piston 6, leather cup 7, cylinder body 4, lining 5, O type circle 8 are formed a sealed space, and the inside is full of brake oil, and the change of oil pressure causes the change of this spatial volume, move thereby promote piston 6, promote clutch separation by push rod 1 again.Dust-proof cover 2 prevents entering of impurity; Snap ring 3 plays positioning action, the position of stationary bushing 5 and cylinder body 4; Spring 9 helps piston 6 returns, plays certain power-assisted effect.Oil inlet hole adopts rapid pipe joint, and is easy installation and reliable.
Therefore, a kind of automobile clutch hydraulic work of the utility model cylinder, with respect to present existing plastics cylinder structure, its contribution is to have increased by two O type circles and lining, makes cylinder body with the light convenience of plastic cylinder and reliable two advantages of metal cylinder body.The scheme of above-mentioned increase lining is actually the motive sealing between leather cup 7 and the plastic cylinder 4 is changed into more the static seal between the lining 5 and cylinder body 4 reliably, between pass through two O type circles 8, further play seal action.
Simultaneously, the oil inlet hole place of master cylinder, prior art adopts worm structure, because injection moulding distortion, thread seal on the plastics cylinder is very undesirable of effect when temperature variation, so the utility model adopts rapid pipe joint, seals between seal ring of doing by rubber 10 and the oil pipe, reached easy for installation, the service-strong beneficial effect.
