Abstract

This invention relates to transport media. The purpose of the invention is to simplify the design. The transmission includes the output shaft 1 of gearbox 2, gears 3 and 4, hydraulic pump 6 with shaft 5, non-rare bridge 7, rear axle 8, propeller shaft 9, gears 10 and 11 with gear coupling 12, rotating two-way connection 13, pipelines 14 and 15 n control device 16, made in the vnde check valve. When Ko.iec slips in the rear axle 8, which exceeds the allowable size, the speed of turning of the shaft 5 will exceed the speed of rotation of the pump 6, the valve 16 will close, as a result of which the shaft 5 will stall against the pump 6, ensuring the automatic activation of the front axle 7. 3 Il.

Description

The invention relates to vehicles and can be used to improve the traction properties of any wheeled vehicles of high traffic.

The purpose of the invention is simplification.

Figure 1 shows the kinematic scheme of a vehicle's transmission; Fig. 2 shows a first embodiment of a hydraulic circuit for connecting a check valve with a hydraulic pump; on fig.Z - the same, the second option.

The transmission consists of a secondary shaft 1, a gearbox 2, gears 3 and 4 connected respectively to the secondary shaft 1 and the shaft 5 of the hydraulic pump 6, which is connected to the i-axle differential, which makes the shaft turn relative to the hydraulic pump and, as a result, pumping the working fluid along the pipeline contour hour hand. Pipeline fluid in this case

5 is pumped freely, the braking torque generated by the hydraulic pump 6 is very small. The hydraulic pump shaft 5 rotates freely without transmitting torque to the front axle of the vehicle. This bridge works as a slave.

If the slip of the wheels of the rear axle exceeds the difference between the theoretical peripheral speeds of the wheels of the rear and front axles, then the actual speed of the vehicle will be less than theoretical. axle 7. Rear drive axle 8 sv - 5 tichesky speed of the front wheels, is engaged with the shaft 1 by means of a cardan shaft. As a result, the hydraulic pump 6 under the action of la 9. associated wheels of the front axle

tends to rotate somewhat slower.

There are gears 10 and 11, fixed respectively on the pump b and shaft 5, and a gear coupling 12, installed at the edge — to pump the liquid through pipelines at least in one of these six-way clockwise, which is not possible with axial movement.

The hydraulic pump 6 is hydraulically connected with a check valve 16 (Figures 1 and 2) through a rotating two-line connection 13 and pipelines 14 and 15. There are 25 as one. As a result, the front axle is also a makeup system, which includes a rigidly connected to the rear axle. A tank 17, a make-up pump 18, a filter 19 and a valve 20. Another option is also possible (FIG. 3). In this case, the hydraulic pump 6 is connected to the check valve 16 through pipelines 14 and 15 and the tank 17.30

Transmission works as follows.

The working fluid in pipes 14 and 15 can be moved through the check valve 16 only in one

Direction: from the pipeline 15 to the front axle 35. In this case, the trawl 14. Therefore, the working fluid MOBILE gear coupling 12 (Fig. 1) moves the path along the contour of the pipelines so that it is located in (Fig. 2) only counter-clockwise. Corresponding x 10 and 11 simultaneously. The shaft 5 is appropriate, rotation of the shaft of the hydraulic pump 6 is rigidly connected with the hydraulic pump 6 relative to its body is possible only in Q, as a result of which, regardless of one side, the hydraulic pump 6 controls movement and the hydraulic shaft 5 is in good condition. In this case, the pump must

because the valve 16 will block the passage from the pipeline 14 to the pipeline 15, and the pump will be blocked. From this moment, the shaft 5 and the hydraulic pump 6 rotate

The middle bridge goes into the drive mode.

The operation of the transmission is the same both when the vehicle is moving in a straight line and when cornering.

When the car is moving backward, the front axle drive cannot work automatically. For this purpose, the transmission provides for a forced switch on the working fluid along the pipeline contour. In the opposite direction, the damage of the shaft of the hydraulic pump 6 is impossible, since the working fluid will be locked in the pipeline 14 and stop the shaft 45 of the hydraulic pump relative to the housing.

When the machine is moving, shaft 1 (Fig. 1) transmits rotation through the drive shaft 9 to the rear axle 8, and through gears 3 and 4, shaft 5 and hydraulic pump 6 to the inter-hydraulic system, torque is transmitted to the front axle.

Claims (1)

Invention Formula A vehicle transmission containing two axles, one of which is kinematically connected to the engine, a hydraulic pump, one element of which is kinematically connected to the drive of one axle. the wheel differential of the front driving axle 50 and the other — another driving axle; axle 7.a of the suction and injection cavities; the hydraulic coefficient of the kinematic nonconversion pump is interconnected through devices of peripheral speeds of the driving wheels in control, which, in order to simplify , the control device is a forward stroke valve, and the drive axles are made with a coefficient of kinematic mismatch of the peripheral speeds of the wheels other than one. bridges in the transmission is not equal to one. It is chosen so that when the vehicle is moving without traction, the driving element (shaft 5) of the hydraulic pump 6 rotates slower than the hydraulic pump 6 itself. It turns the shaft around the hydraulic pump and, as a result, pumping the working fluid through the pipeline contour counterclockwise. Pipeline fluid in this case pumped freely, the braking torque generated by the hydraulic pump 6 is very small. The hydraulic pump shaft 5 rotates freely without transmitting torque to the front axle of the vehicle. This bridge works as a slave. If the slip of the rear axle wheels exceeds the difference between the theoretical circumferential speeds of the rear and front axle wheels, then the actual vehicle speed will become less than the theoretical circumferential speed of the front wheels. As a result, the hydraulic pump 6 under the action of the front axle wheels associated with it  pump the fluid through the pipelines in a clockwise direction, and this cannot than shaft 5. In this case, the pump must pump the fluid through the pipelines in a clockwise direction, and this cannot  as one. As a result, the front axle is rigidly connected to the rear axle. Pe- because the valve 16 will block the passage from the pipeline 14 to the pipeline 15, and the pump will be blocked. From this moment, the shaft 5 and the hydraulic pump 6 rotate as one. As a result, the front axle is rigidly connected to the rear axle. Pe- front axle suspension. In this case, the gear clutch 12 (Fig. 1) is required to be persdvi- way so that it is located on gear 10 and 11 simultaneously. The shaft 5 in this case is rigidly connected with the hydraulic pump 6, as a result of which, regardless of the direction of movement and the health of the hydraulic bridge, it passes into the mode of operation of the drive axle. The operation of the transmission is the same both when the vehicle is moving in a straight line and when cornering. When the car is moving backward, the front axle drive cannot work automatically. For this purpose, a forced torque system is provided in the transmission system and transmitted to the front axle. Invention Formula 55 Fig.2 f6 P 77 Editor N. Margolin Order 734/19 Compiled by S.
