    The invention provides a modification to a wheel hub of the kind comprising a hollow body housing a wheel speed reducer having a pinion carrier which is locked for rotation with the hollow body. According to the invention, splined mounting means is provided between the pinion carrier and the hollow body for locking the pinion carrier in rotation with the hollow body. Mounting means of this kind require only a small radial space, and the radial bulk of the assembly can therefore be reduced with this arrangement. The invention is particularly applicable to the hubs of driving wheels for industrial vehicles, agricultural machines, public works machines and load-handling machines.

    专利说明:

    The invention relates to wheel hubs with an integrated gearbox, used, for example, for equipping trucks, agricultural machines, public works machines or for cargo mechanisms such as cranes and cranes.
    The purpose of the invention is to reduce the size.
    FIG. 1 shows the wheel hub axial section; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a view B in FIG. 1 with a half axial section B-B in FIG. one.
    Wheel hub 1 (Fig. 1) is the hub of the motor wheel and is designed to be mounted on a fixed hub 2 (trunnion), which in turn is attached to the end of the place in which the corresponding shaft (not shown) of the wheel is rotatably mounted.
    The wheel hub 1 contains a generally tubular hollow body 3, which is rotatably mounted on a trunnion with a gasket of two PEDYTIPNIKS 4, and is closed in the transverse direction by a removable kryppka 5 on the opposite side of the indicated stud (} s.
    On the outer side, the hollow body 3 has a photo-dance 6 on which a corresponding wheel can be put on, through the rim shell, and on this flange there are holes for mounting the wheel studs on this flange.
    The hollow body 3 is corrugated in a circle on the side of the flange opposite to the cover 5, i.e. on the side of this flange located on the side of the trunnion and thus radially forms the cells 8.
    In the hollow case 3, a gearbox 9 ko, scaffolding is installed on the side of the cover 5. I
    In addition, a brake 10 is installed on the side of the trunnion.
    The wheel reducer 9 contains a plurality of intermediate gears evenly distributed around the axis of the mechanism 11, each of which is mounted separately with the possibility of rotation around the bearing shafts 12 mounted on the holder 13 intermediate gears, which is on the hollow housing 3.

    contains two disks 14 and 15, the first to close proximity to the cap 5, and the second one at a distance from the latter, between which the bearing shafts 12 intermediate gears 11 are located and which are connected to each other in the axial direction by means of levers 16 alternating in a circle with specified carrier shafts 12.
    Known intermediate jaws 11 are installed between the planetary shaft 17, designed to join, when rotated, to the wheel shaft, and the ring gear 18, which, when rotated, rotates with the carrying transverse disk 19 (ring gear carrier, which in turn is fastened to the trunnion).
    The planetary shaft 17 is fixed axially to the transverse disk 14 of the holder of intermediate gears 1 1 by means of friction washers 20, and the planetary shaft 17 for this purpose passes through the transverse disk 14 by means of an axial nozzle 21, which has an axial retention spring 27 at its end mechanism.
    In addition, in this embodiment, the crown gear 18 in the axial direction consists of two respectively connected, for example, welding parts, and between its holder 19 5 and the trunnion are mounted on the end of the trunnion, working around the circumference of the cam connection 23 for the desired installation, and 24, operating in the axial direction.

    The same applies to the performance of the brake 10 and its controls.
    The brake 10 contains a plurality of brake discs 25, which are connected when rotated with the bearing hub 26, and which, alternating with the intermediate disks 27, which are connected while rotating with the ring gear holder 19, can be axially subjected to the action of the control box 28. compression between the ring 29 is forced, the support ring 30, which in turn rests axially against the cover 5 by means of pins 31 passing axially through the supporting shafts 12 intermediate gears 11 and levers
    16 holders 13 intermediate gears.
    In the shown embodiment, the control unit 28 comprises a working piston 32, the cylinder of which 33 can be connected to a source of fluid under pressure, and a spare piston 34 which, having discs of the disc spring 35, can act on the working piston 32 and the cylinder of which 36 is typically connected to a source of fluid under pressure, other than the previous source, to provide backwater.
    In the illustrated embodiment, the planetary shaft 17 can be connected when the wheel is rotated to the wheel shaft by means of the carrier disc 26 of the brake discs, the carrier hub 26 having inside the grooves for engaging both this planetary shaft and the wheel shaft.
    For connection when rotating the intermediate gear holder 13 with the hollow body 3, it is provided to install a flute circuit 37 between this holder 13 intermediate gear and the said hollow body 3.
    In the illustrated embodiment, this cannelure circuit 37 is installed between the peripheral portion of the transverse disk 14 of the holder 13 intermediate gears and the inner wall of the hollow body 3, with this peripheral portion having for this purpose radially protruding teeth 38 that engage with the teeth 39, which also for this purpose, they are radially formed on said inner wall.
    In addition, since the intermediate gear holder 13 is a part separated from the key 5 and the latter rests in the axial direction, as described below, on the hollow body 3, said intermediate gear holder 13 is fixed by axial thrust rods 40 to the specified crest 1 - ke 5, and in the direction of the latter it rests in the axial direction on the removable means 41 of the stop, which in turn is fixed in the axial direction on the hollow body 3,
    In the illustrated embodiment
    axial rods 40 are made in the form of screws, which are evenly distributed in a circle and pass tightly through the cover 5, the entrance to the bore holes 42 in the transverse disk 14 of the holder 13 intermediate gears, the stop means 41 are made in the form of a spring-ring split entering the groove 43 This hollow body 3 has a step 44 on the inner edge of its corresponding section for the axial stop closing its crutch 5, which is made in the hollow body 3, and the said lid 5 has a radial flange 45, which is additionally indicated Nomu ledge 44 hollow body 3 can serve as a stop.
    The lid 5 has in the direction of the spring-ring split, which acts as the stop means 41, an axial nozzle 46, which reaches directly to the latter.
    However, taking into account the inevitable tolerances in the manufacture, there remains a minimum gap 1, between the end of the axial nozzle 46 of the roof 5 and the spring-loaded split ring, forming the stop means 41.
    The same applies to the gap Ij, which is present in the groove 42 of the hollow body 3, with the split spring acting as a stop means 41.
    During the screwing up of the screws constituting the thrusts 40, the lid 5 by means of its flange 45 abuts axially into the hollow body 3 and at the same time the holder 13 of the intermediate gears by means of its transverse disk 14 abuts axially into the spring-split ring the stop and axially abutting against the sides of the groove 43 of the hollow body 3, which it extends, the groove is closest to the said cover 5.
    Thus, the intermediate gear holder itself provides axial retention of the cover 5, as well as
    own axial retention. I
    At the same time, taking into account the inevitable tolerances during assembly, p is the opposite of the gaps 1, 1 and also taking into account the flexibility of the spring split ring forming the stop means 41, the installation of the holder 13 intermediate gears relative to the crown gear 18 is performed in a floating mode within certain limits
    regardless of its blocking with the latter during rotation.
    In addition, there is an advantage in the rigid connection of the ring gear 18 with its holder 19.
    Koronna gear 18 is practically complete together with its holder 19.
    Since the spring-loaded split ring in the form of an emphasis 41 means

    but removable, if desired, you can easily have access to the internal volume of the hollow body 3.
    Indeed, it is sufficient to ensure consistently, after removing the screws, which act as tg 40, to remove the cap 5, the spring ring in the form of the stop means 41 and the holder 13 intermediate gears.
