Abstract

Изобретение относитс к транспортному машиностроению и может быть использовано при ресурсных испытани х тракторов. Цель изобретени - повышение надежности. На основании 1 шарнирно установлены ведущие 8 и нат жные 9 колеса, охваченные бесконечными гусеничными обводами 4, башмаки которых контактируют с тормозными плитами 3, создава при движении сопротивление вращению. К башмакам прикреплены упругие ленты, на концах которых закреплены П-образные кронштейны , внутри которых размещены отрезки тросов с ограничительными упорами. При набегании беговой дорожки 10 на ведущие 8 и нат жные 9 колеса линейный зазор между внутренними торцами П-образных кронштейнов увеличиваетс без раст жени лент, что повышает надежность стенда. 4 ил.The invention relates to a transport engineering and can be used for life tests of tractors. The purpose of the invention is to increase reliability. On the base 1, the leading 8 and tension 9 wheels, which are enclosed by infinite caterpillar contours 4, are pivotally mounted, the shoes of which are in contact with the brake plates 3, creating resistance to rotation when driving. Elastic tapes are attached to the shoes, at the ends of which U-shaped brackets are fastened, inside which are placed segments of cables with restrictive stops. When running treadmill 10 on the leading 8 and tension 9 wheels, the linear gap between the inner ends of the U-shaped brackets increases without stretching the tapes, which increases the reliability of the stand. 4 il.

Claims

Claim

A vehicle test bench comprising a base, drive wheels and idler wheels pivotally mounted on the base and covered by endless caterpillar tracks with a treadmill, and brake plates mounted on the base with the possibility of contacting with caterpillar tracks, characterized in that, with In order to increase reliability, treadmills are formed by ribbons made of elastic material and connected in series by means of flexible elements provided with limit stops at the ends and placed axial displacements in the U-shaped brackets, while the U-shaped brackets are attached to the ends of the tapes, and the tapes are fixed on the endless caterpillar contours with a step selected from the condition t = L <2S, where t is the step of fixing the tapes on the endless caterpillars contours;

L is the length of the tape;

S is the length of the plot of the endless caterpillar contour between the support point of the mover of the test vehicle and the inflection point of the endless caterpillar contour on the drive or idler wheels.
