(57) Abstract:Usage: the invention relates to articulated vehicles, in particular trucks. The inventive upper swivel semiframes allows relative movement semiframes. The lower swivel such a move does not allow. It is equipped with two bearings, made in the form of axial bearings 16 and 17, mounted on a vertical finger 10, the connecting lugs 6 and 8 semiframes. The bearing 16 is installed between the pressure sleeve 18 and the cover 11 of the roller bearing, and the bearing 17 is between the lower ring 6 and the cover 12. 4 C.p. f-crystals, 4 Il. The invention relates to the transport industry, in particular to articulated vehicles, and can be used to swivel semiframes, such as forklifts.Known coupling semiframes articulated vehicle containing located on the vertical axis of the upper and lower swivel made in the form of vertical fingers connecting the contacting lugs semiframes, fitted tapered roller bearings is and the expense of the clamping bushing, acting on the inner race of tapered roller bearings. On each finger mounted on two bearings in one housing (1). During operation of the vehicle tapered roller bearings are exposed to both axial and radial loads. The axial force from one of the semiframes through the sleeve is transmitted to the inner race of the bearing and then through the rollers on the outer casing and the lugs of the second semi-frames. When this tapered roller bearings are the most loaded element coupling semiframes articulated vehicle.Known coupling semiframes articulated vehicle containing are located on the same vertical axis of the upper and lower swivel made in the form of vertical fingers connecting the contacting lugs semiframes, fitted tapered roller bearings, closed lids. At least one of the hinge joints, mainly the bottom, not allowing relative vertical movement of semiframes, has a set of clamping sleeves, acting on the inner race of tapered bearings mounted in pairs in one case the taper bearings are the most loaded element swivel.This disadvantage is eliminated by the fact that in the known coupling device semiframes articulated vehicle containing located on the vertical axis of the upper and lower swivel made in the form of vertical fingers connecting the contacting lugs semiframes, mounted with roller bearings, closed lids, at least one of the hinge joints, mainly the bottom, not allowing relative vertical movement of semiframes has a clamping sleeve. This swivel is equipped with two bearings mounted on a vertical finger, the first of which is located between one cover roller bearing and clamping sleeve, acting through the thrust bearing on this cover, and the second between the ring frame and the other lid. Bearings, in particular, can be made in the form of axial bearings of the polymer composite. Clamping sleeve provided with a flange that interacts with the eyelet semi-frames through the shims and roller bearings upper and lower hinge joints made double row angular contact spherical.SOP the bearings, installed on a vertical finger, the first of which is located between one cover roller bearing and clamping sleeve, acting through the thrust bearing on this cover, and the second between the ring frame and the other lid. Bearings made in the form of an axial slide bearings made of composite material, the clamping sleeve is made with a flange engaging the eyelet semi-frames through the shims and roller bearings made double row angular contact spherical.The influence of axial forces from the clamping sleeve and the lugs semi-frames via axial bearings on the cover tapered roller bearings allows to unload cartridge bearings, to increase the reliability of hinge joints, to create a compact design of the drawbar semiframes by reducing the dimensions of the hinge joints. Implementation of sliding bearings made of composite material to ensure their durability, which increases the reliability of the coupling. The presence of shims under the flange of the retainer sleeve provides backlash-free connection between the sliding surfaces of the bearing and cover.In Fig. 1 shows a truck with articulated frame; Fig. 2 hitch semiframes; Fig. 3 an enlarged image of the upper swivel of Fig. 4 an enlarged image of the lower swivel.Truck 1 has a semi-frames 2 and 3 interconnected by a coupling device 4. The section 2 is provided with a lug 5 and a pair of lugs 6, and section 3 by a pair of lugs 7 and 8 eyelet. Lugs 5 and 7 of the upper swivel bound by the finger 9 and the lugs 6 and 8 of the lower swivel
finger 10. The fingers 9 and 10 into the holes of the lugs 5 and 8 installed double-row radial spherical roller bearings, caps 11 and 12 are attached to the lugs by means of bolts 13. Roller bearings have inner 14 and outer 15 clip.The lower swivel is supplied to the bearings 16 and 17 made of composite material mounted on the finger 10 and in contact with lids 11 and 12 of the roller bearing. Clamping sleeve 18 has a flange 19 and through the shims 20 are connected with the upper lugs 6 by means of bolts 21. The finger 10 is fixed in the lugs 6 g is omnitele secured against falling out by bolts 27.The top swivel is designed in a way that allows relative vertical movement of semiframes 2 and 3. The lower swivel prevents such movement.When working or just the movement of the vehicle when turning semiframes relative to one another effort from one of the semiframes transferred to another via a swivel. When radial forces are perceived roller bearings and vertical fingers 9 and 10. Axial force from one of the semiframes, for example 2, through the lugs 6, the sleeve 18, the bearings 16 and 17 is transmitted to the lid 11 and 12 radial spherical roller bearing, which is pressed against the lug 8 semi-frames 3. Therefore, when the transfer of force from one semi-frames to the other of the shroud 14 and 15 of the roller bearing is unloaded from axial forces. When turning semiframes 2 and 3 relative to each other is sliding bearings 16 and 17 on the covers 11 and 12 radial lower bearing swivel. 1.
