Abstract

The invention relates to a test apparatus. The purpose of the invention is to accelerate the 19.5-17 Sch tests by doubling the number of simultaneously tested objects. The stand contains a drum 1 formed by a cylindrical shell 5, two outer 6, 7 and 8 middle discs. The middle disk 8 is connected through bearings 3, 4 to axis 2, outer disks 6, 7 have central holes closed by covers 10. Links 17 and 18 test tracks interacting with test subjects are laid on inner raceways of drum 1 on treadmills 15 and 16. support rollers 21 and 22. Sand, snow, gravel and other ingredients can be introduced into the cavities through the funnels 12. 18 I - 7 cl with Yu VJ ov

Description

The links 17, 18 for unloading the middle disk 8 and its bearings 3, 4 can be spring-loaded by springs 20, simulating axial load on the links and rollers, in opposite directions. After re-assembly, elements of wheeled transport vehicles can be installed in the internal cavities. The outer treadmill 14 drum 1 is in frictional engagement with the outer test wheel 24 by a rotating drive 29 It is possible to test simultaneously the douh variants of the elements of the tracked (or wheeled) vehicle chassis systems in the inner, drums and one more variant of the running wheel system of the outer the treadmill of the drum while reducing the loading of the stand 1 z p p, ly, 2 Il.

The invention relates to the wcnbnaren technique, which is mainly used for testing the undercarriage systems of transport vehicles, and is an improvement of the device according to aut. No. 1458753.

The purpose of the invention is to accelerate testing by doubling the number of objects simultaneously tested.

The stand for testing the elements of the conveyor systems of the transport machines contains a drum 1 rotating about axis 2 on bearings 3 and 4. The drum is formed by a cylindrical shell 5, left b, right 7 and middle 8 face discs. The middle disk 8 is a cheoez bearing 3 and 4 connected to an axis 2 fixed on the stand 9 of the stand, on the extreme disks 6 and 7 the central apertures covered with lids 10 are blotted out. The covers 10 have hatches And for installation in the inner cavities of the drum 1 of the tested running gear systems transport vehicles

The introduction of gravel, sand and other environmental ingredients into the internal cavities of the bore- wind (or B one of them), in which the drive system can actually work, of the transport vehicle, the covers 10 are fitted with funnels 12. The hatches 11 of the covers 0 are sealed with membranes 13 of - pevlagonepronitszemy fabric.

Drum 1 has an outer 14 and inner left 15 and right 16 runners. On the inside of the racetracks 15 and 16, tracks of links 17 and 18 are laid (for example, a left track of links 17 of a single design, a right track of links of another construction 18) fingers 19 Link 17 and 18 (go one any of them) can be spring-loaded along the track fingers 19 with springs 20. Moreover, springs 20 of one treadmill at diametrically opposite points of drum 1 are installed from different gtoro i links. Links 17 and 18. lying approximately on the same generator of the drum, in order to reduce the drag force on the drum 1 and its bearings 3 and J PSDpr / inen in opposite directions. Through the hatches 11 of the grooves 10 in the inner parts of the drum 1, the support rollers 21 and 22 are installed (the pinto 21 is all-metal, the right 22 are rubberized). The track rollers 21 and 22 are pressed against the links 17 and 18 by means of loading devices 23 through the tested suspension elements of the transport vehicle.

Instead of pj3i variants, both elements of the same construction can be installed in both oi.yrnamental cavities (for speeding up a set of statistical data) or cavities (for obtaining comparative data) can be filled with different 1 / i

environmental ingredients

When testing the components of the undercarriage system of a wheeled vehicle, for example, 4, a tractor, a car, instead of the track wheels of a tracked vehicle, wheels can be placed in the inner parts of the drum, mounted on the front or -. in the afternoon of the bridge of this machine. In this case, the caterpillar from the internal cavities of the drum can be mounted through the hatches of the covers.

Underneath the support rollers, the driving roller or test wheel 2 is pressed against the outer surface of the drum 1, which is installed in the support 25 fixed on the platform 26, rocking relative to the axis 27, parallel to the axis of the drum 1. The wheel 24 is pressed against the drum 1

Claims (2)

The leading roller, getting rotation from the drive 29, drives the drum 1 with the links and 17 and 18 tracks laid on its internal treadmills. At zeny 17 and 18, the support rollers 21 1 22 Hack as links are laid on the treadmills a snake, then, rollers with their flanging collars assist with ridges of links, imitating the operation of the suspension system on a slope, while turning. At the same time, the links of self-alignment in the direction of the track finger along the supporting rollers of the links 17 and 18 in opposing directions are axial force eq is weighed (fully or partially; 1 on the middle face disk 8 and bearings 3 and 4 is not transmitted the Formula from Capture 1. Stand for testing of our own, our first transport 0 five fsk 1458753, differing in heme, that, with the whole acceleration of testing due to doubling the number of simultaneously tested objects, the drum is doubled and symmetrical with respect to the vertical perpendicular to the axis of rotation of the plane and has two isolated from each other internal treadmills formed by three end disks bearing and connected to the axis of rotation of the drum 2. The stand according to claim 1, characterized in that in order to reduce the axial load on the paraban and its bearing assembly, the track links of the treadmills on the same forming drum are spring-loaded in opposite directions 25 Fig 2
