This publication applies, in particular, to a method of Assembly of the disk t is Rosa, in particular, Assembly converts the movement of the cartridge, which converts the rotational movement of the brake lever in the forward movement of the brake piston to turn off or deactivate the Parking brake.

In the known construction the rear part of the cartridge contains a pin mounted in the slot in the bottom of the slot, intended for installation of the cartridge in the cylinder bracket brake. This design is relatively complicated to manufacture and installation, and the pin when the Parking brake is exposed to significant torque forces.

The objective of the invention

The task underlying the present invention is to simplify the manufacture of the bracket brakes, reducing the number of parts in the composition converts the movement of the cartridge, and to eliminate the risk of deformation (buckling) of the elements of the bracket in its manufacture.

Disclosure of the invention and its advantages

To this end offered a disc brake of the type specified above, characterized in that:

A) transforming the movement of the cartridge (transducer motion) is:

- back, resting in the bottom slot of the cylinder and includes:

* support in the form of a sleeve with a flange resting in the bottom of the socket around is made in the bottom of the through-hole through which partially passes sleeve, and

* shaft control the Oia, connected to the Parking brake lever and provided with a first disk; and

- the front part, rests on the brake piston is installed with the possibility of translational movement relative to the cylinder, but are fixed against turning with respect to it, and includes:

* pusher, comes with a second disk that interacts with the first drive shaft control by moving balls located between the sloping surfaces of the two disks, for converting the relative rotational motion between the two disks in the forward movement of the pusher,

* ring (casing) that is holding the plunger in the cylinder by a spring clip,

* return spring located between the yoke and the plunger for resisting forward movement created by the disks and balls;

B) the cylinder at the level of its rear end forming a socket for transforming the movement of the cartridge has at least one longitudinal groove and the plunger has on its periphery at least one longitudinal protrusion, the cross section of which corresponds to the cross section of the longitudinal groove to communicate with the groove and fixing the front part of the Chuck from turning with the freedom of translational movement of the pusher;

In) protivodetonatsionnuyu eliminate the STV, located between the projections of the pusher, on the one hand, and the slots of the slot of the bracket, on the other hand, and containing ring with lugs, distributed around the circumference of the ring, respectively, the location of the longitudinal projections of the pusher and having a cylindrical lugs, curved essentially in the cross-sectional shape of the longitudinal protrusions in order to close the latter in the longitudinal grooves of the socket cylinder.

Thus, the fixation of the follower, i.e., the movable threaded sleeve of the Chuck from turning implemented directly on the bracket; the plunger is prevented from turning longitudinal (s), protrusion (s) located on the front of the cartridge and the like (s) in the form of longitudinal (s), groove (s) provided in the slot of the cartridge, made in the bracket, and between the protrusion (s) and groove (s) is protivodetonatsionnuyu device.

Thus, a significant advantage of the invention is the exception to the design of the rear casing of the cartridge, and a pin mounted in a hole in the bottom bracket of the rear holder from turning. In accordance with the invention, the yoke rear part of the famous cartridge replaced with a simple back support with L-shaped profile in longitudinal section. The exception cage rear improves the draining of the brake circuits, i.e., blugaria is there a drain brake fluid, as proposed in the invention converts the movement of the cartridge does not contain any components with closed cavities. This simplifies the manufacture of the shroud and reduces the length of the cylinder, or the notches in the bracket in which is located the bullet.

The invention also simplifies the Assembly of the cartridge, which is conducted in the framework of the technological process of Assembly of the brake, eliminating the use of special equipment to receive the cartridge Assembly. The clip is not already latched on the back of the Chuck body, which eliminates the risk of the formation of burrs.

Finally, the invention can be implemented in relation to the pistons or plungers of a smaller diameter than the pistons or plungers, currently in use, at a constant generated by their efforts.

In a preferred embodiment of the invention the slot of the cartridge in the clip has three longitudinal groove, and a plunger provided with three longitudinal ribs, wherein the longitudinal grooves are evenly distributed around the circumference of the socket, i.e., are arranged at equal angular distances from each other, and the protrusions are respectively the location of the slots.

These three longitudinal groove in cooperation with three longitudinal protrusions provided on the pusher, well keep the plunger from turning, while allowing you to avoid the problems associated with the considerable torque, which can be attached to the plunger by means made in the form of a ball transfer connection between the disks. This excellent fixation from turning also favors the reverse movement of the pusher when you turn off the Parking brake.

In yet another preferred embodiment of the invention at least one longitudinal groove of the socket has the contour of the cross section in the shape of an arc of a circle, in particular in the form of a semicircle, and a longitudinal protrusion on the plunger has a similar cross-section, i.e. the cross-section in the shape of an arc of a circle, homothetic arc of a circle cross-section of the groove, taking into account the thickness protivodiareynogo device. Groove and projection of this form is very simple to manufacture.

In another preferred variant of the invention, the longitudinal protrusion is made in the form of a rod, passing backward from the second disk and covering the rear part of the transformative movement of the cartridge at least part of its axial length.

The length of the longitudinal protrusion, which is, therefore, oblong execution is the rod (crest), in particular when there are multiple longitudinal protrusions formed on the plunger, which is preferably equal to three, perfectly provides the direction of movement of the plunger, i.e., PLA is of the forward movement in the slots as guides, and fixation (from turning) of the pusher in the bracket without any risk of deformation. Rods, bent back, allow to reduce the axial length of transforming the movement of the cartridge, and not to the detriment of the quality of the direction of movement of the pusher, especially because the rods are supported in surround them free space as a back support, and a disk on the shaft of the control cartridge. In these conditions, even the impact on the rods significant efforts cannot squeeze the rods from their grooves, because the rods are held in the slots and to some extent locked in there with the rear part of the cartridge protivodiareynogo device.

In yet another preferred embodiment of the invention the nest cartridge has a shelf made to stop him contour of the shroud, and a circumferential groove, made under the spring holder.

In yet another preferred embodiment of the invention the clip is a product made of elastic steel, made in a generally conical shape and having a base in the shape of the crown, from which emerge the petals are connected to the rim and located between the intermediate petals of the adjacent their free ends with spring holder.

Such holder and its interaction, first, with the ledge, and secondly, with OK uznam groove, in which is located a spring holder, guarantee excellent stopping converts the movement of the cartridge in its slot by a geometric circuit. This stopper can not open spontaneously. To open it you will need a special tool, such as a sleeve acting on the ferrule conical shape for the gradual release of petals clip that allows you to display split the rim and release it from the groove. Installation is carried out in the same conditions by performing actions in reverse order.

In General, disc brake equipped with such a transformative movement of the cartridge with protivodetonatsionnuyu device is easy to manufacture and assemble due to the reduced number of parts. The invention provides an excellent functioning brakes and ensures its reliability.
