This design provides the possibility of mounting the thin-walled cylinder and the weight of the whole site. 1 C.p. f-crystals, 2 Il. The invention relates to the field of transport engineering, namely, devices mounting cylinder clutch vehicles.A device mounting cylinder of the clutch, comprising a thick-walled molded case cylinder mounted in the bore tide clutch housing (see the book "Car "Moskvich-2140", edited by I. K. of Chernikova, M.: engineering, 1982, page 108, 110, Fig. 68, 69).Closest to the claimed of the known technical solutions is a device for fastening the clutch, comprising a housing cylinder with its fastening elements made on the body in the form of bosses (tides), through which the casing by means of bolts fixed to the clutch housing (see the book: L. P. Shuvalov "Car "Lada", M: DOSAAF, 1972, page 132, Fig. 4-7).The disadvantage of this device is the complexity of the design and manufacture of the cylinder by increasing the mass of the node.Currently in wide use are thin-walled, Stampa-welded cylinders, which have a much smaller mass than the thick-walled cast. However, to fix them as described above, it is impossible, as they are unable to perceive the external radial load on his thin body.Object of the invention is the provision of opportunities for fixing the thin-walled cylinder of the clutch, which causes the reduction of weight of the whole site (the cylinder with its fastening elements).To solve the problem in the device mounting cylinder of the clutch, comprising a housing cylinder, the elements of its fastening through Kotor is received in the form of covering the body of the cylinder curly brackets, on the surface of which, facing the enclosure ditch, covering the collar is made on the housing, and between the clutch housing and the cylinder body is installed curly spring, the middle part clamped to the curly bracket.It is advisable on the shoulder of the cylinder barrel to perform the chamfer is in contact with the surface of the bolt to ensure the orientation of the cylinder in space.A comparison of the proposed technical solutions with the level of technology on scientific, technical and patent documentation on the priority date shows that the set of essential features of the proposed solution was not previously known, hence it corresponds to a condition of patentability "novelty."Analysis of the known technical solutions in the field of technology have shown that the proposed device has the features which are absent in the known technical solutions, and their use in the inventive combination of features gives the opportunity to learn new technical effect. Therefore, the proposed solution involves an inventive step compared to the current level of technology.The proposed solution Promyslov, hence corresponds to a condition of patentability "industrial applicability".The invention is illustrated in the drawings, where Fig. 1 shows the cylinder of the clutch device with its mounting; Fig. 2 - section a-a in Fig. 1.The device includes a housing 1 cylinder, which is covered by the curly bracket 2 made of light alloy. On the surface of the bracket facing the cylinder, the groove 3, in which is placed a collar 4, is made on the body, perceiving the axial forces which occur during operation of the cylinder. To ensure installation of the housing 1 inside the bracket 2 between the housing and the crankcase 5 clutch is curly spring 6, which is the middle part 7 draws in the housing 1 of the cylinder to the curly bracket 2 secured by bolts 8 to the sump 5 clutch. Moreover, the flange 4 of the casing may be placed in the area of the bolt 8 and has a chamfer 9 in contact with the surface of the bolt. This determines the orientation of the cylinder in the space to ensure pumping of the hydraulic drive (remove the air), for which the fitting 10 pumping must be directed upwards.The above-described device is used as follows. Curly bracket 2 podsobirajte 3 bracket, what is provided under the condition of the location of the flats 9 flange above the surface of the bolt 8. Then on the threaded portion of the bolt is installed curly spring 6, facing the middle part 7 to the body 1 of the cylinder. Then the device together with the cylinder by means of bolts 8 is fixed to the crankcase 5 clutch.Thus, the use of the above described device provides the possibility of securing a thin-walled cylinder with no application to his case invalid axial loads. 1. The device mounting cylinder clutch of a vehicle, comprising a housing cylinder, the fastening elements through which the casing by means of bolts fixed to the clutch housing, characterized in that the fastening elements made in the form of covering the body of the cylinder curly brackets, which on the surface facing the frame groove, covering the flange on the housing, and between the clutch housing and the housing is installed curly spring, the middle part clamped to the curly bracket.2. The device under item 1, characterized in that the flange of the case is made flats in contact with the surface of the bolt.
