    1531770 Positive clutches IFA GETRIEBEWERKE BRANDENBURG VEB 16 Dec 1976 [23 Dec 1975] 52501/76 Heading F2C In a friction synchronized positive double clutch for a change speed gear wherein initial axial movement of an internally toothed clutch sleeve 3 engageable with teeth 19, 20 on clutch elements 6, 7 acts through a detent 14 and a hub 2 to move synchronizing rings 4, 5 into engagement with friction surfaces on the clutch elements 6, 7, the detent 14 and a detent 10 which centres the hub 2 between the clutch elements 6, 7 comprise spring-pressed balls 14, 10 in stepped radial bores 12 in the hub 2. The spring 13 acting on the ball 14 is stronger than the spring 9 acting on the ball 10 to ensure that the hub 2 moves relative to a shaft 1 to initiate synchronism prior to movement of the sleeve 3 relative to the hub 2 for clutch engagement.

    one
    FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular, to the construction of stop-synchronizing devices for reversible gear mechanisms.
    The closest in technical essence to the present invention is a stop-synchronizing device for reversible gear mechanisms, comprising a carriage mounted on a shaft with radial holes, a coupling sleeve placed in each hole of the carriage two balls acting on the spring balls and the spring separating element G1
    However, when the carriage is axially moved, its external or internal ball or both can be squeezed out first from its locking position, either, which does not guarantee the required precise sequential control of the device and decreases its reliability.
     The purpose of the invention is to increase the reliability of the locking synchronization device.
    The goal is achieved due to the fact that the radial holes of the carriage are made stepped, the step of larger diameter is facing the coupling, the balls have
    2
    different diameter, according to the steps of the holes, springs; made of different stiffness, the spring of greater stiffness is placed in a step of larger diameter, which is equal to the diameter of the spring separating element.
    The drawing shows a diagram of the proposed device.
    The device comprises a carriage 2 mounted on the shaft 1 with radial holes having two stages of a larger diameter 3 and a smaller diameter 4 and a coupling 5 with a hole 6. The carriage 2 is equipped with
    5 conical sleeves 7 and 8, which are rigidly connected with it, and which have the ability to interact with rotating cones 9 and 10, are fixed on the gear wheels to be coupled. Holes in the carriage 2
    0 are stepped, the larger-diameter stage 3 faces the coupling 5, and the smaller-diameter stage 4 to the shaft 1. In each section of the cage, there are two balls 11 and 12, springs 13 and 14 and a spring-separating element-washer 15. Balls 11 and 12 have a different diameter, respectively, the steps of the holes, and the springs 13 and 14 are made of different stiffness.
