The invention relates to the field of engineering, in particular to the automotive industry, and can be used, for example, as a brake device for assembling and post processing of vehicle parts.

Known disk brake (JP 2869016, IPC 6 F 16 D 55/224)containing a pair of levers, friction discs, the drive and parallel disks. Levers pivotally supported in the center by means of holders. Friction drives can be connected and disconnected through the pads, hinged to one end of the levers. Drive the tilt lever provides a mechanical clamping surfaces of the rotating disc of the friction disks. Parallel discs connected pads and holders and support friction discs parallel to the end surfaces of the rotating disk.

This disc brake has the following disadvantages: significant size and complexity of the design.

Also known disc brake with opposite pistons (JP 2861217, IPC 6 F 16 D 55/22), which contains two clamping disc brake pads, independently pressed against opposite them dished pistons. Inside the open front of the cavity formed in each of the pistons, is the liner having a plot of torque transmission with almost the same diameter as the internal diameter of this cavity.

And the known device is difficult to manufacture due to the need to provide increased accuracy of the mating parts.

The closest in technical essence to the proposed technical solution is disc brake (DE 19735127 C1 IPC 6 F 16 D 55/224)containing two levers, bearing two opposite brake pads. One end of the levers fixed hinge, and the other is connected through a driving shaft. Driving shaft one end of which is pivotally connected with the first lever and the other with a bow, with which the second lever pivotally connected at a point on the distance from the point swivel with clip driving shaft. The stirrup under the action of the actuator can be rotated for frictional circuit and open circuit brakes. To increase the braking force point swivel driving shaft with the stirrup is located on the outer side of the hinge axis between the stirrup and the first lever.

However, this disk brake has a limited scope, as it cannot be used for braking vehicle parts as brake design complicates the approach to the brake pads.

This invention is aimed at expanding the scope, functionality and usability. For this purpose, the brake mechanism comprising two pivotally interconnected lever and two opposite brake pads, mounted on the levers with the possibility of periodical in which aimogasta with a rotating disk, equipped with a pneumatic cylinder. Pneumatic cylinder mounted on one end of the levers in such a way that its body is mounted on one lever, and the rod on the other. Brake pads installed on the second end of the levers, swivel are placed between the brake pads and cylinders. One of the brake pads made in the form of conductive bus, spring relative to the lever and capable of connecting to a voltage source. Levers made spring-loaded relative to each other by means of tension springs installed between the swivel levers and pneumatic cylinder. The rotating disk is made of two parts rigidly interconnected at their bases, one of them installed with the possibility of contact with the conductive line made of conductive material and provided with an element to relieve her tension.

Figure 1 presents a General view of the brake mechanism, figure 2 - callout a in figure 1.

The brake mechanism includes two levers 1 and 2. Opposite the brake pads 3 and 4 mounted on one end of the levers 1 and 2 and interact with the rotating disk 5. Brake pad 4 made in the form of conductive bus, and is spring-loaded relative to the lever 1, the plate spring 6 (see figure 2), and is connected to a voltage source (not shown). Rotate the different disk 5 is made of two parts 7 and 8, rigidly interconnected bases. One of the parts 8 are installed with the possibility of contact with the conductive bus 4, is made of conductive material and is equipped with element 9 to relieve her tension. Pneumatic cylinder 10 is mounted on the second end of the levers 1, 2 and is connected to a supply of compressed air (not shown). The housing of the pneumatic cylinder 10 is fixed to the lever 1, and the rod on the lever 2. The levers 1, 2 are interconnected by a swivel 11 placed between the brake pads 3, 4 and cylinder 10. The levers 1, 2 are biased relative to each other by means of tension springs 12, 13, are installed between the swivel 11 and cylinder 10.

The device operates as follows.

In the initial position, compressed air from the device for the supply of compressed air is not available and the piston rod of the pneumatic cylinder 10 is retracted, the levers 1, 2 divorced, brake pad 3 and the current-carrying bus bar 4 is not in contact with the rotating disk 5, that is, it is in motion. When applying compressed air to the pneumatic cylinder 10, the piston rod extends. The levers 1 and 2 are rotated around the axis of the swivel 11 and press the brake pad 3 and the current-carrying bus 4 to the rotating disk 5 (det. POS. 7 and 8, respectively). Is the braking of the rotating disk 5, and then to the conductive bus 4 carts is camping voltage, which is transmitted to the conductive part 8 of the rotating disk 5, whence it is removed by means of element 9 and is used, for example, welding, power tools or any other consumers, certain process. The plate spring 6 tightly presses the current-carrying bus 4 to the conductive part 8 of the rotating disk 5, thereby ensuring a reliable contact for transmission of tension between them. When the supply of compressed air to the pneumatic cylinder 10, the levers 1 and 2 under the action of the tension springs 12, 13 are returned to their initial position. Brake pad 3 and the current-carrying bus 4 free rotating disk 5. Then the cycle repeats. Thus, due to the application of the brake pads in the form of a spring-loaded conductive bus, a rotating disk, which consists of two parts supplied element to relieve tension, the brake mechanism acts as a brake and energy supply, that is, expanding the scope, functionality and ease of use.

Brake mechanism comprising two pivotally interconnected lever and two opposite brake pads, mounted on levers with periodic interaction with a rotating disk, characterized in that it is provided with a pneumatic cylinder mounted on one of the samples of the levers so his body is fixed on one arm, and a rod on the other, with brake pads installed on the second end of the levers, swivel are placed between the brake pads and cylinder, one of the brake pads made in the form of conductive bus, spring relative to the lever and capable of connecting to the voltage source, and levers made spring-loaded relative to each other by means of tension springs installed between the swivel arm and the cylinder, the rotary disk is made of two parts rigidly interconnected at their bases, one of them installed with the possibility of contact with conductive line made of conductive material and provided with an element to relieve her tension.
