Abstract

Improvements in the construction of oscillating front support for self-transported concrete mixer, which are characterized in that the reducer housing, previously installed on the concrete mixer shaft, is laterally provided with two opposite symmetrical appendages, configured below in the form of a spherical cap for each of them, articulated to a corresponding spherical cavity practiced in an arcuate groove for slidably engaging a corresponding arcuate raised guide arranged on a support base fixed to the frame of the vehicle, said guide being arched internally provided with a slot equally arched, provided that the two said appendices are vertically perforated for the passage of the shank of a screw whose head is hingedly coupled to the mouth of the hole of the corresponding appendix, while the end is provided with a nut that, through a spring, elastically squeezes the aforementioned appendage against said underlying annular element and the assembly against said supporting base, thus also passing said shank to said arcuate groove, finally providing that the middle lines of said arched guides and of the corresponding arched grooves are disposed on a same circumference whose center is preferably at the point of intersection between the horizontal radii, coplanar and symmetrically inclined at 45º with respect to the projection of the axis of the concrete mixer on its plane and said projection.
