    The invention relates to controls for changing the direction and speed of movement in a hydraulic gearbox having several forward and reverse speeds, namely to lever shifting mechanisms for effecting the switching of direction and speed in said gearboxes.
    The purpose of the invention is to simplify the design.
    Fig. 1 shows a lever mechanism with parts of a directional selector valve, side view; Fig, 2 7 the same rear view.
    The lever mechanism 1 for switching the gearbox 2 has an input element 3 having the first 4 and second 5 arms, respectively, positioned relative to each other at an angle of 90 °. The link 3 is pivotally fixed on the bracket 6 rotatably around a horizontal transverse axis as the hinge pin 7, which passes through link 3 at the junction of the shoulders 4 and 5. When the link 3 is in the central neutral position, the first shoulder 4 is horizontal, and the second shoulder 5 is vertical.
    The upper end of the first output link 9 is pivotally attached to the shoulder 4 along the third finger 8, the upper horse of which is pivotally connected to the upper end of the spool 10 of the direction selector valve 11 by means of the finger 12. The spool 10 is depicted in the neutral position N, from which it can be moved up to position F for forward gear, or down to R for reverse gear.
    The first output link 9 has the ability to increase or decrease its length from the normal state in response to the predetermined resistance to movement along the length that occurs. The link 9 has an upper first section including a solid part 14, made in the form of a rod placed with the possibility of reciprocating motion in part 13 and held in a normal position in place with respect to the last with the help of a spring-loaded stop ball 15 placed in the upper tubular part 13 and entering into the annular groove 16, which is provided in the lower part 14. The direction selector valve 11 has a spring-loaded stopper ball 17, mounted with the possibility of pliable placement in the upper 18, between full-time 19 and lower 20 grooves formed on the circumference on the body of the spool 10 for a corresponding retention of the spool 10 in its positions when performing the rear, neutral and front gears. Above the upper groove 18 is an upper flange or flange serving as the upper stop 21, and below the lower groove 20 an annular flange or flange serving as the lower stop 22 is located. The spring-loaded stop ball 17 is intended for a flexible release of the spool 10 when the latter acts the force of a given value from the first output link 9, and the specified force of a given value is less than
    a predetermined resistance for achieving elongation or contraction of link 9, with the result that link 9 always triggers to move the spool 10 in position to get the front, neutral and reverse gears and lengthens or decreases only when the stopper ball 1 7 engages with one of the stops 21 and 22. For example, it was found that link 9 is working properly if locking ball 15 is released from groove 16 under a load of 35 pounds (15.88 kg) to lengthen or shorten link 9, and stop ball 1 7 is released from any of the grooves 18.19 and 20 of the spool 10 under a load of 25 pounds (11.34 kg).
    To the lower end of the link arm 5 is pivotally connected by means of a connector 23 with a ball and a socket below it, the lower end of the second output link 24 having a bent upper end 25 that is pivotally fixed at the upper end of the spool valve body of the speed selector valve 26. the first speed, from which he has the possibility of shifting upwards to the position of the second and third speeds). It should be noted that when the input link 3 is in the neutral position, the line drawn by the opposite ends of the link 24 crosses the axis of rotation of the input link. Thus, when the input link moves in opposite directions from the neutral position, the second output link 24 and, therefore, the speed selector valve 26 are moved.
    At point 27 on bracket 6, a push-pull cable 28 is fastened with a movement back and forth, and a pin 29 is passed through an earring attached to the rear end of the cable, which connects the earring to the 5-link arm below the hinge pin 7. Front end cable 28 is connected in a similar way with the lower end of the speed selector lever 30 fixed by the middle part by means of a finger 31 with the possibility of swinging both ways from the neutral position N into a series of three forward speed positions
    F, F and FJ and the three rear speed positions R, R and RJ.
    The device works as follows.
    Suppose the lever mechanism 1 is in the position depicted in the drawings. In this case, the speed selector 30 is in the neutral position, and the input link 3, in the corresponding neutral position, holds the spool 10 of the direction control valve in its neutral position, therefore. and the gearbox 2 is in the neutral position.
    If the transmission needs to be set to the first-speed switch-on state, it is enough for the operator to move the shift lever 30 forward to the F position. The cable 28 transmits this movement to the input link 3, which moves to the desired position corresponding to F. During this movement, the input link 3, the first output link 9 moves the slide valve 10 of the directional selector valve to the up and down position F of the forward gear. Moving the input link 3 causes only the minimum displacement of the second output link 24, and due to gaps in the junctions of the link 24, the selector valve of speed 26 does not shift.
    The gearbox 2 is shifted to the second forward speed by moving the shift lever 30 further forward to the FJ position. The cable 28 transmits this movement to the input link 3, as a result of which the latter moves to the position corresponding to F-. The initial movement of the link 3 encounters resistance due to the fact that the locking ball 17 rests on the lower stop 21. However, after the resistance of the movement leads to the appearance of a force sufficient to overcome the force holding the locking ball 15 in place, the link 9 is lowered. After the link 9 falls, the movement of the input link 3 continues and causes the second output link 24 to move the selector valve spool to the F position corresponding to the second speed.

    The gearbox of the second gear is shifted to the third speed, as is the switch to the second gear. 5, however, in this case, the first output link is already omitted, with the result that the ball does not provide initial resistance to the movement of the input link 3.
