Abstract

The clutch casing, made in the form of a plate, on which there are pads with holes for bolts attaching the casing to the flywheel, a pressure disk with a pressure spring is installed inside the casing, characterized in that the mounting holes are additionally made on its platforms, along the axes of which on the side surface of the casing cutouts are made to accommodate the heads of the bolts for the possibility of attaching the casing to the flywheel with the existing mounting holes for the clutch of a smaller size.

The utility model relates to mechanical engineering and can be used in vehicle transmissions.

Known clutch containing a casing, mounted with bolts on the flywheel, a pressure disk mounted in the casing. The pressure disk contacts the cups in which the pressure springs are placed. On the pressure plate mounted stops, adjustable in height with a slot and locknuts. On the casing there are locking bolts located in the grooves of the pressure plate. This constructive solution allows you to adjust the clutch safety factor while maintaining constant effort on the controls by the required value of the frictional moment of the clutch during rotation of the pressure plate and the corresponding change in the force of the pressure springs (see, AS.SSSR N 1451372, Cl. F16 D13 / 42 , 1987).

The closest technical solution to the claimed one is the clutch cover described in the Volga Gorky Automobile Plant Parts Catalog, Moscow, Engineering, 1991, pp. 49-50 or in the book of V.I. Anokhin Domestic Cars, pp. 315- 322, fig. 220 and 225, Moscow, Mechanical Engineering, 1977.

The clutch casing is made in the form of a plate on which there are platforms with holes for bolts securing the casing to the flywheel. The casing has ventilation windows, and a pressure disk with a pressure spring is installed inside the casing.

On the sites of the well-known casing, there are mounting holes of only nominal size. This design solution of the casing is used to connect the coupling and the flywheel of one size, and when connecting this casing to the flywheel of a different, smaller size, it is necessary to open additional mounting holes on the flywheel, because the coordinates of the mounting holes of the clutch of different sizes do not match.

The proposed clutch casing is made in the form of a plate with ventilation windows and has platforms with holes for bolts securing the casing to the flywheel, a pressure disk with a pressure spring is installed inside the casing. A distinctive feature in the claimed casing is the presence of additional mounting holes on the platforms with cuts made along the axes of these holes on the side surface of the casing to accommodate the bolt heads, which makes it possible to fasten the casing to the flywheel with the existing mounting holes for the smaller clutch.

This design provides the ability to connect the casing with a flywheel of a smaller size without opening on the flywheel additional mounting holes for a clutch of a larger size.

This technical solution was proposed in connection with the need to transfer more torque due to the increased power of existing engines and to achieve the greatest unification of clutch couplings.

The proposed clutch cover is shown in the drawings

Fig, 1 - view of the clutch, top view;

FIG. 2 is a view B of a cutout in a side surface of the casing of FIG. 1;

- 2 figures, 4 - section along BB, fixing the cat to the flywheel of nominal size.

The casing 1 of the clutch is made in the form of a plate with ventilation windows (not shown in the drawing). On the casing 1 there are platforms 2 (marked with a dotted line) with holes 3 on the nominal diameter D for bolts 4 securing the cat to the flywheel 5, On the sites 2 there are additional mounting holes 7 on the smaller diameter d and with an angular displacement e, along the axes 1 of which are on the side cutouts 8 are made for the surface of the casing 1 to accommodate the heads of the bolts 9 for the possibility of attaching the casing 1 to another flywheel 6 with the existing mounting holes for the clutch of a smaller size. Inside the casing 1, a pressure disk 10 with friction linings 11 and a pressure spring 12 are installed,

The use of the proposed casing is as follows. The clutch of a larger size with the claimed casing 1 through additional mounting holes 7 made on a smaller diameter bis angular offset "from the holes 3 to prevent overlapping holes 3 and 7 on each other and cutouts 8 on the side surface of the casing 1 under the head of the bolts 3 is installed on the flywheel with existing mounting holes for a smaller clutch. For example, the clutch with the proposed casing can be installed on both the ZMZ-406 engine and the ZMZ-402 engine,
