TRUCK-MOUNTED CONCRETE MIXER AND ITS CONNECTING STRUCTURE Russian patent published in 2015 - IPC B60P3/16 

FIELD: machine building.

SUBSTANCE: invention relates to construction equipment. The truck-mounted concrete mixer has chassis, subframe and drum installed on the supports on the subframe. The subframe contains side elements. At least rear support of the drum is secured to the side elements of the subframe via the resilient elements with shapes coordination. At least one connection for the drum rear support securing to the side element of the subframe of the truck-mounted concrete mixer has a connection structure located inside the section width of the side element. The connection structure has at least one supporting structure located on the top side of the side element section. The drum support located on the side element of the supporting surface of the of the supporting structure located within the profile width of the side element. The connecting structure essentially is located in area of the supporting surface. The connection element is essentially connected to the side element with shapes coordination in the vertical direction, and/or in the longitudinal direction, and/or in the transverse direction, and/or in relation to the rotating movement around the vertical axis of rotation. The supporting structure has the receiver for the connecting element.

EFFECT: design improvement of the resilient connection of the drum rear support.
