Description

(54) MULTI-POWER VEHICLE

I

This invention relates to vehicles, in particular to their transmissions.

A multi-axle vehicle is known, containing the main and additional extra drive axles and a control system for the latter, consisting of a sensor and load loaded in the form of a cam coupling, one coupling half of which is fixed on the main drive axle drive shaft, and a friend with axially displaced and spring loaded relative to the post, switch on with actuating cylinders located in the drive of additional driving axles, and the controlled distributor, is spring loaded dQ spool which is bonded via dvuhppechego rpaga the movable coupling half, schzhchem input distributor associated with the pressure istoch11kom 1.

The disadvantage of this vehicle is the complexity of the transmissions, which consist in the presence in the drive of each additional load and distributor bridge, which also reduces its durability.

The purpose of the invention is to increase the permeability while increasing durability.

The goal is achieved by the fact that the distributor is made multi-conscious, the output of each position of which is associated with the controlled cavity of the corresponding actuating cylinder, with the number of positions of said distributor being equal to the number of axles of the vehicle.

15, the additional driver axles 2 and 3 contain a sensor 4 and a load, made in the form of a cam coupling, transfer case 5, pressure source 6, distributor 7, the input of which is connected to the pressure source. The movable coupling half 8 dacha 4 load is spring-loaded relative to the drive shaft of the main driving bridge. The kinematic coupling of the movable coupling half 8 with the spool of the distributor 7 is made in the form of a double-arm lever 9. The fixed coupling half 10 of the loading sensor 4 sits on the drive shaft of the main driving axle connected to the engine shaft 11. The drain line 12, the lines 13 and 14 for switching on the actuating cylinders 15 and 16 constitute the communication loop of the individual elements of the said system for switching on additional driving axles. The main 1 and additional 2 drive axles are connected to the transfer box with 5 shafts 17 and 18, and the additional drive axle 3 is connected to the shaft 19. The distributor 7 is equipped with the return valve 20 return distributor 20 and the pedal 21 forcing the bridges. The distributor has three positions 22-24. Transmission works as follows. With increasing loading of the shaft 17 of the main drive axle 1 driven from the shaft 11 through the transfer box 5, the movable cam coupling half 8 moves and through the lever 9 acts on the valve 7. The valve 7 moves to position 23 and informs the pressure source 6 with the line 13, which is communicated with an actuating cylinder 15. The actuating cylinder 15 closes and activates an additional drive axle 2. If the loading continues to grow, the moving coupling half 8 moves further in the axial direction and The lever 9 sets the distributor to the position 24. The pressure source 6 through the lines 13 and 14 communicates with the actuating cylinders 15 and 16, which include additional driving axles 2 and 3. When the load decreases, the driving half coupling B moves in the opposite direction and alternately turns off additional bridges 3 and 2. The distributor 7 is then returned to the position 22 by the action of the spring 20 and reports the pressure source 6 to the drain line 12. The pressure in the working cavities of the actuating cylinders. 4 15 and 16 falls, and the additional bridges are turned off. To force additional drive axles, it is necessary to act on the distributor 7 by pressing the pedal 21. At the same time, the distributor moves and turns on additional drive bridges, regardless of the position of the moving half of the hull. improves vehicle throughput and durability. Claims of the invention A multi-axle vehicle containing the main and included additional drive axles and the latter control system, consisting of a load sensor, made in the form of a cam clutch, one coupling half of which is fixed to the drive shaft of the main driving axle and is spring-loaded with respect to the latter, the clutches with actuating cylinders, located in the drive of additional driving axles, and the controlled one will distribute He has a spring-loaded spool which is connected by means of a double-arm lever with a movable coupling half, the inlet of the distributor being connected to a pressure source, characterized in that, in order to increase the maneuverability while simultaneously increasing the durability the cavity of the corresponding actuating cylinder, wherein the number of positions of said distributor is equal to the number of axles of the vehicle.
