Hydrocodoneapapsolution vehicle

 

(57) Abstract:

Usage: the Invention relates to the transport industry, in particular to hydrocodonealprazolam devices to change and stepless speed tractors and similar machines. The inventive block pumps hydrocodoneapapwhatis made in the form of one gear hydraulic machine with a sections of gears-off valves arranged in pairs-symmetrically around a Central gear-rotor. Section gears-off valves serially connected with the motor-wheel or disable. 2 Il.

The invention relates to the transport industry, in particular to hydrocodonealprazolam devices to change and stepless speed tractors and similar machines.

Known hydraulic woodworking machine with automatic reversal of the hydraulic motor while simultaneously stepless change speed (ed. St. USSR N 389924, B 27 B 5/00, 1973). However, it is difficult due to the mechanical connection of the control.

Closest to the invention is hydrocodoneapapsolution vehicle containing block pumps, kinematically tie the N 1243972, B 60 K 17/10, 1983).

The disadvantage of hydrocodoneapapwhatis is used in the hydraulic system, multiple pumps, which complicates the kinematic relationship and increases the cost.

The basis of the invention is a technical challenge to create hydrocodoneapapsolution, which would at the simplicity of the design ensured the functionality of the hydraulic system of the object, simplifying the design and reducing the cost.

The problem is solved in that in hydrocodoneapapwhatis vehicle containing block pumps, kinematically connected to the motor, and powered through the control valve motor-pump connected with the propeller according to the invention the block pumps made in the form of one gear hydraulic machine with a sections of gears-off valves arranged in pairs-symmetrically around a Central gear-rotor and having the possibility of serial connection-disconnection from the motor-pump.

Equipment hydrocodoneapapwhatis multiple gear with hydraulic machines provides multithreading working environment and allows you to adjust the speed of the motor-pump through a serial connection to it sections gears-OYA scheme hydrocodoneapapwhatis; in Fig. 2 - a-a in Fig.1.

Hydrocodoneapapsolution vehicle contains multiple gear hydraulic machines 1 with a Central gear-rotor 2 and placed around it and held in engagement gear cut off 3. The hydraulic machines kinematically connected with the motor 4. In the discharge lines of the sections gears-off valves 3 is a valve 5, which provides consistent connection / disconnection with the motor-pump 6, which is connected with the propeller 7.

Hydrocodoneapapsolution works as follows.

The motor 4 rotates the Central gear-rotor 2 and are with her in the meshed gears-off valves 3, creating pressure working environment. The valve 5 provides a serial connection with the motor-wheel (motor pump) 6, which, in turn, is connected with the propeller, providing the necessary speed of the vehicle.

Thus, the supply of hydrocodoneapapwhatis vehicle multiple gear with hydraulic machines provides the necessary regulatory regime, simplifying the design and reducing the cost.

Design hydrocodoneomatropine the tailor tools, containing block pumps, kinematically connected to the motor, and powered through the control valve motor-pump connected with the mover, characterized in that the heat pump is designed as a gear hydraulic machine with a sections of gears-off valves arranged in pairs-symmetrically around a Central gear-rotor and having the possibility of serial connection-disconnection from the motor-wheel, with the valve installed in the discharge lines of the sections gears-off valves.
