Abstract

Изобретение относитс к автомобилестроению. Цель изобретени - повышение долговечности. Опорно-поворотный круг прицепа содержит верхнее и нижнее поворотные кольца, выполненные с беговыми дорожками. Кажда из беговых дорожек выполнена с двойным контактом с телами качени . Дорожки имеют кольцевые проточки, расположенные в месте сопр жени поверхностей, образующих беговую дорожку. Поверхности образованы дугами окружностей, центры которых смещены относительно центра тела качени . 2 ил.This invention relates to the automotive industry. The purpose of the invention is to increase durability. The slewing ring of the trailer contains upper and lower slewing rings made with treadmills. Each of the treadmills is made in double contact with the rolling elements. The tracks have annular grooves located at the junction of the surfaces forming the treadmill. The surfaces are formed by circular arcs whose centers are displaced relative to the center of the rolling body. 2 Il.

Claims

The invention The slewing turntable of the trailer, the invention relates to the automotive industry, in particular to the slewing turntables of the trailers.

The aim of the invention is to increase durability.

FIG. 1 shows a turning circle, a cut; in fig. 2 - the same, on an enlarged scale.

The turntable contains the top 1 and bottom 2 slewing rings.

Ring 1 has a treadmill 3, biting upper and lower swivel rings, and ring 2 has a treadmill 4 with a ring-made with treadmills, on forged grooves ni, n of radius g. Rolling bodies are located, different tracks 3 and 4 form a channel. In that, in order to increase the size of the body, 5 rolling bodies from the upper edge are each spaced out, each of the treadmills with a height of 6 points of contact. The conjugated tracks are filled with double contact with the bodies of the surface of the treadmills in contact with the rolling and with ring grooves, the surface of the rolling body 5, and the surfaces 6 of the rolling body 5 of the protrusions forming the treadmill, comes along two pads A, B of ring 1 than the surfaces of the treadmills in cross section and C, D of ring 2 at an angle and a cross section formed by arcs of circles,

The force P from the load is transferred from the top-20, the centers of which are displaced relative to the center of the ring 1 to the lower ring 2 when

ra body rolling.

the help of treadmills 3 and 4 and the rolling bodies 5 through the contacting contact surfaces A, B and C, D and surfaces 6.

Such a combination of surfaces increases the contact area by 2 times.

The invention The slewing circle of the trailer, containing the upper and lower slewing rings, made with treadmills, on the bark of the rolling body.
