Usage: used in the field of transport, mainly in brake mechanisms of the vehicle. The inventive brake mechanism includes a rotating brake drum 1, the non-rotating brake pads 2, Rethimno fist 8, additional brake pad 4 and the drive cylinder 5. Brake cylinder 5 additional presses the pad 4 to the drum 1, while Rethimno fist 8 is translated into position and presses the brake pads 2 to the drum 1, stermaria it. 1 Il.

The invention relates to the field of transport, mainly to the brake mechanisms (TM) vehicles.

The most common are the friction, the principle of which is based on the friction of the rotating parts of the non-rotating. In the form of rotating parts TM are divided into drum and disc. Non-rotating parts drum TM can be pads or tape, disc pads only. Tape drum TM consists of rotating and non-rotating drum of the tape (see the Car. Based design. M. engineering, 1986, S. 226). Disk TM consists of a rotating disk and newradius. ibid S. 227), TM have Rethimno a device that provides a contact of the working parts when braking. Expanding devices are wedge and in the form of a camshaft fist working when turning. Work expanding device using the drive mechanism, which may be in the form of a lever, hydraulic and pneumatic cylinder or air chamber. Also known drive mechanism in the form of a brake cylinder, a weight-bearing function of the camshaft.

The disadvantage of the listed TM is a direct dependence of the efficiency on the magnitude of the effort on the drive and the inability to use the kinetic energy of the rotating parts to brake.

The closest to the proposed device is a drum drum TM from the expansion device in the form of a fist (see the book of the Braking device. Guide, p/p Alexeev M. P. M. engineering, 1985, S. 81-82, Fig. 2.32), containing a rotating brake drum, a non-rotating brake pads, Rethimno device in the form of a fist, working in turn, connected through a lever mechanism of the camshaft drive device in the form of an air chamber, which is provided by compressed air from the brake system. Nedostatki energy. At the same time rotating parts TM have kinetic energy, which is desirable to use camshaft device.

This is achieved by the fact that in TM with equal displacements pads containing a rotating brake drum, a non-rotating brake pads, Rethimno device in the form of a fist, working when turning, the drive mechanism in the form of a cylinder provided with an additional brake pad, which may be against the rotating brake drum. Brake cylinder mounted on Rethimnon Cam, translates it into its working position, in which brake pads are pressed against the brake drum. The braking torque depends on the degree of entrainment of additional drum pads, and the degree of entrainment depends on the strength of cuddling additional pads to the drum. Thus the work of the camshaft device is provided by the kinetic energy of a rotating brake drum, then there is a process requireany energy.

The supply of the drive mechanism of the additional brake pad that is pressed against the rotating parts, translates Rethimno device in working position, allows independent is to be the work of the camshaft device due to the kinetic energy of the rotating parts.

This invention is illustrated in the drawing, which shows the recovery of TM in the cut. The mechanism consists of the drum 1, block 2, mounted on the axles 3, additional pad 4 attached to the piston of the brake cylinder 6, the return spring of the piston 7, a brake cylinder mounted on Rethimnon Cam 8, is made to rotate on the supporting sleeve 9. The supporting sleeve 9 is fixed on the supporting disk 10. The fist is equipped with a return spring 11 and is mounted on the trunnion 12. Pads 13 provided with a compression spring.

Works TM as follows. The piston 5, the brake cylinder 6 additional presses the pad 4 to the rotating drum 1. Captured by the additional drum pad rotates Rethimno fist 8, which presses the pads 3 to the drum 1. Is braking.

The brake mechanism containing a rotating brake drum, a non-rotating brake pads, Rethimno fist for brake pads, brake cylinder to drive the camshaft fist into the operating position, characterized in that Rethimno fist equipped with an additional Shoe made with the possibility of its drive through the brake cylinder to bring in additional interaction is
