The braking force create impact on the pinion gear of the transmission, which is a brake Shoe acting on the friction surface of the gears and the fluid between the teeth. Gear is converted to hydraulic machines. The control device includes a transmission gear and the brake is made with nuts. The hydraulic machines can make and brake, and the driving effort. 2 S. and 2 C.p. f-crystals, 7 Il. The invention relates to a method and controls tractors, cars, Agronomico and other mobile machines.There is a method of machine control, which form the leading efforts with the transmission gear and braking effort. The method is implemented by the transmission gear and brake with friction surfaces and damping of kinetic energy.The prior art is characterized by the fact that separation and contraction f is of the metal, the cost and danger.This objective is achieved in that the braking force create impact on the pinion gear of the transmission, brake Shoe affect surface friction gears and the fluid between the teeth with the possibility of conversion gear in hydraulic machines. The brake is made with nuts, which is installed with the possibility of contact with the driven gear gear transmission. The brake is made in the form of hydraulic machines with the ability to create the driving effort. Gear block is converted into hydraulic machines. The function of the gear pump and brakes combine and combine. To control the use of the advantages of mechanical and hydraulic transmission and conversion gear in hydraulic machines when forming the driving and braking forces. In the main gear bevel gear press Shoe during braking and held in a predetermined position of the pad during movement. The symmetry of the shape of cylindrical gears for use management and resource conservation by turning after wear one side. Gear used as multifunctional hydraulic machines. The axial travel of the wheel COI is achi press to leading during braking with greater force and as a source of strength using a brake pad.Gears are made symmetrically and installed can be rotated after the limit of wear on one side of the teeth. Friction surfaces of the brakes is made on the gear and pads installed with the possibility of education of the pump. The wheels are positioned on the rim of the brake drum. The friction surface has a taper and is made with the possibility of braking in the event of axial movement of the wheel.In Fig. 1 shows a diagram of a gear-brake with friction surfaces on the pinion gear of Fig. 2 diagram of the gear blocks, side view; Fig. scheme 3 gears brakes-hydraulic-brake; Fig. 4 scheme of the place of contact of the gear with the plates and pads hydraulic and mechanical braking; Fig. 5 the flow of symmetric gears plugs; Fig. 6 scheme brakes main gear and wheel rim; Fig. 7 diagram of the brake of the wheel rim, side view.The control method implemented by the device containing the transmission gear 1 (Fig. 1 3) on-Board gear, which the STB 2 is transformed into hydraulic machines, suction line which is composed of 3 radial plate and side blocks 4 cylinder 5 brake, output shaft 7, associated with the wheels of the Board pads 4 and 14 (Fig. 4) when braking. Fork gears 17 and 18 on the spline shaft 19 can move the gear 20 on the gear 20 of the driven shaft 21 of the transmission.The brake pedal 22 (Fig. 6) is connected with the pads 23 and hydrocortison 24 main gear 25 and the thrust 26 block 27 emergency braking rim 28 of the wheel 29 of the lever 30.Gears 1 with the set-top box 2, plate 3 and the pads 4 are hydraulic machines (pump, motor) driven cylinders 5 and 13, and a mechanical brake on the surfaces of the gears. The cylinders 8 and 10 with the rail 9 and the lever 11 can rotate the gear 12 for zero turning radius and to block the transmission gear in the Parking lot. The plug 17 can move symmetric gear, and the symmetry allows the rotation of the gears after wear the one hand to continue the other party.When implementing the method, the device operates as follows. Gears 1 with the device 2 when the pressing plate pads 3 and 4 operate as a pump: suck oil and served in the pressure line and the cavity of the hydraulic cylinders 5 and 13. When the fluid pressure in the pressure line turns the pump in the brake hydraulic brake and pads with the friction surfaces of the gears provide magadalene pump hydraulic system creeper gearbox. The cylinders 8 and 10 with the rail operate the motor and turn the gears and the car, and when the fluid flow only into the cylinder 10 hold the gear 12 and the car in the Parking lot. Therefore, the side gear works hydraulic and mechanical brake and the motor depending on the position of the pads and commands of the driver. During retraction of the pads from the gears function of pump brake stop. The ability to rotate the gears and work the back side of the teeth doubles the resource.When exposed to the pedal 22 block 23 and hydrotherms 24 main gear 25 through the rod 26, block 27 with the rim 28 inhibits the wheel 30. Block 23 presses the gear 25 and the main transmission eliminates damage to their teeth and provides braking. Axial movement of the wheel without effects pedal provides braking by tapered friction surfaces. When using gear as a brake means of the hydraulic and mechanical braking, combined member functions brakes operate faster, are light weight, low cost. 1.
