    In a steering control valve device of the kind utilizing a metering pump and a torsional stress means for returning the flow control valve sleeve to a neutral position, there is provided a coupling sleeve between the manually operable steering spindle and the valve sleeve. Such coupling sleeve is for the purpose of providing an intermediate actuating member between the steering spindle and the valve sleeve to overcome errors in alignment and other disadvantages which can occur in conventional constructions where the steering spindle directly actuates the valve sleeve wherein rotation of the steering spindle effects axial shift of the valve sleeve for flow control purposes. The invention is particularly advantageous where the means of translating rotary motion of the steering spindle to axial movement of the valve sleeve is effected by threaded coaction.

    one .
    The invention relates to the field of transport engineering, and more specifically to vehicle steering control systems.
    A hydrostatic steering of a vehicle is known, which contains a manual gear pump having a gear ring fixedly fixed to the body with internal teeth and a gear with external teeth located inside the gear ring, the number of gear teeth is one less than the number of teeth of the gear ring, propeller shaft drive shaft with gear and installed with the possibility of rotation and axial movement relative to the housing, and spring elements, moreover predelitelny spool is hydraulically connected to the hydraulic pump, hydraulic reservoir and through the manual gear pump - hydraulic cylinder lj.
    However, the known steering has the disadvantage that, due to the misalignment between the drive shaft and the rotary distributor spool, for example, due to increased friction, the rotary distributor spool is seized in the housing.
    The aim of the invention is to increase the reliability of operation.
    This goal is achieved by the fact that the hydrostatic steering system is equipped with a connecting cardan compensating coupling installed inside the distribution spool, the hinge of which is made with a cross spline connected to the drive shaft, cardan shaft, and through a threaded guide rib and helical threading - with the distribution spool moreover, the spring elements are connected on the one hand with the connecting leg, and on the other hand, with the propeller shaft and fixed against their mutual rotation.
    Screw threading is made in a three-way way; in addition, the device is equipped with a finger, and on the coupling sleeve there are two opposing f ac-positioned slots, bounded by their respective sides, and the coupling sleeve is set to 909802
    Lena with the ability to interact with the finger, which is fixed in the driveshaft without a gap.
    1 shows a hydrostatic steering {in FIG. 2 a transverse section A-A in FIG. 1; on fig.Z - cross-section bb in figure 1} in figure 4 - transverse section bb In figure 1.,
    10 A toothed ring 1 with internal teeth is installed (Figures 1-3) between the cover 2 and the intermediate intermediate ring of the housing 3 and is connected to it and to another insulating cap.
    5 4 by means of screws 5. A gear 6 with external teeth, having one tooth less than a gear ring 1, forms with a gear ring 1 between the teeth of both parts and the adjacent
    0 to gear 6 with face surfaces of Krish 2 and housing 3 displacement cells 7.
    The gear 6 through the drive shaft 8 and the driver 9 is connected to the side clearance with the coupling sleeve 10, which, in turn, through the hinge 11 is connected to the cross recess with the drive shaft 12 ..- In the internal bore 13 of the housing 3 a rotary distribution valve 14 is mounted coaxially with a coupling 10, which is installed using the direction of the 5th rib 15. A three-way thread 16 and 17 is provided in the coupling 10, as well as in the rotary valve. This coupling 10 is installed in the rotary slide 14.
    The rotary slide valve 14 through a three-way thread 16 and 17 has the possibility of axial displacement relative to the coupling 10 and limited rotation to the stops 18. Between the coupling 10 and the drive shaft 8 a pair of flat springs 19 and 20 is installed. Two leashes 9 and 21 serve for a comprehensive hinge
    0 connection without the possibility of rotation between the gear 6 by the driveshaft 8 and the rotary slide 14.
    Thus, the relative rotation between the coupling 10 and
    5 with the drive shaft 8 is possible up to the stops 18, which limit the two opposite spline 22 in the coupling 10, which are opposite each other. The leash 9 (fig. 3) is connected to these radial splines 22, which can be rotated without the possibility of turning. 9 is installed radially without a gap in the inner hole of the coupling 10. To install the coupling 10 without the possibility of axial displacement, it is on the one hand,. rests on the thrust surface 23 of the drive shaft 12 and, on the other hand, resists the thrust disk 25 on the thrust surface 24, and the thrust disk 25 in turn rests on the propeller shaft 8. For adjusting the pressure and distribution of the working fluid, the body 3 and the spool 14 are made in the following way: the central inlet groove 26 is connected to the hydraulic pump 27 and connected to the internal part of the rotary slide 14 through the inlet channel 28. Two co-connectors with the inlet groove 26 and the outlet of the groove 29 and 30 communicate with hydraulic tank 31. each And from the cylindrical grooves 32 or 33 located near the exhaust grooves 29 and 30 are connected with one of the three chambers 34 or 35 of the hydraulic cylinder 36. On the outer side surface of the rotary slide 14, annular grooves are installed in a known manner, which in the neutral position of the rotary slide 14 enable circulating the working fluid with almost no loss of pressure from the hydraulic pump 27 to the hydraulic tank 31 of the working fluid, and in the axially displaced position of the rotary slide 14, they block the free flow and connect one of the two on either end of the rotary slide valve, two systems 37 and 38 are installed evenly distributed around the perimeter of distribution grooves 39 or 40. The distribution longitudinal grooves 39 and 40 of both systems 37 and 3 are offset relate one. the other half of the gear teeth division. In addition, the necessary end-to-end longitudinal grooves 41 and 42 and the end-to-end internal pro with grooves 43 are provided for supplying the working fluid from the supply channel 28 to one of the systems 38 of the distribution longitudinal grooves 40. The distribution longitudinal grooves 39 and 40 are closed in the neutral position of the rotary slide 14. In the rotational positions of the rotary slide 14, the distribution longitudinal grooves 39 of one of the systems 37, depending on the steering direction, are connected to the inlet channel 28 or the cylindrical groove 32, and the distribution longitudinal grooves 40 of the other system 38 - to the cylindrical groove 33 or to the inlet channel 28. i The connection of the pressure cells 7 with the distribution longitudinal grooves 39 and 40 occurs through the guide channels 44, the axial channels 45 and two systems of distribution holes 46 and 47. The execution of the guide channels als axial channels 44 and 45 is known. The number of axial channels 45 corresponds to the number of valleys between gear teeth 1.. The distribution holes 46 and 47 are made as drilled holes that start from the axial channels 45 and are drawn in the internal hole 13 of the housing 3. In this case, two distribution holes 46 and 47 start from the axial hole 45, for example, from the axial channel 48 - hole 49 and 50. One hole 49 leads to one of the systems 3-7 and the distribution longitudinal grooves 39, another hole 50 leads to another system 38 of the distribution longitudinal grooves 40. When the steering wheel is rotated, the leading shaft 12 and, through a cross-hinge joint 11, coupling sleeve 10 against the forces of both flat springs 19 and 20. Both flat springs are mounted with a bulge in the axial longitudinal direction and their bulge rests centrally on each other. curved on both sides, ends 51 and 52, they rest on coaxially interconnected bearing surfaces 53 and 54 of the coupling and spring support 55, which is connected without possibility of rotation with the cardan shaft 8. Figure 2 shows a transverse section of the hydrostatic power steering in neutral
    position with coaxial bearing surfaces 53 and 54, as a result. The compression elements act only in the circumferential direction.
    The rotation of the drive shaft 15 causes the slide 14 to move to its operating position. If the force acting on the drive shaft 12 is directed against the action of the springs, the latter are removed, and the potential energy that is stored in the flat springs 19 and 20 is sufficiently large.
     to move the rotary slide 14 through the three-way thread 16 and 17 again to its neutral position.
    5 Due to the fact that the coupling sleeve Yu is trimmed from the drive shaft 12 and installed in the rotary slide valve only by means of the guide rib 15 and the three-way thread, 10 radial components of the forces that could lead to the jamming of the slide valve 14 in the inner bore, so excluded ..
