Patent ID: 8651398

Claim:
A central bar for spraying and/or distributing products in powder, liquid and granulate formulations, the central bar being located between a front wheel and a rear wheel of a vehicle to reduce oscillation caused by the vehicle driving over irregular terrain, by a tandem effect caused by the location of the central bar, said central bar comprising: a central frame set including two top subsets, two bottom subsets, a horizontal pantograph subset, two vertical pantograph subsets and damping bearings; wherein top side arms are hinged by balls and cross pieces, causing three-dimensional movements of two side bars; wherein the horizontal pantograph subset connects the two side bars; wherein the two vertical pantograph subsets work together in solidarity through an alternator axis; wherein the top subsets each include a bearing bracket, internal brace with ball and pin, attachment brace with said ball and cross piece, cross piece bracket and first hydraulic actuator; wherein the bottom subsets each include a bar terminal, an attachment brace with ball and cross piece, and second hydraulic actuator; wherein the horizontal pantograph subset includes bottom side arms, stabilizing bar and brackets, which are fixed to form a single rigid component; wherein the horizontal pantograph subset connects both of said two side bars by means of said stabilizing bar; wherein the vertical pantograph subsets are driven by said second hydraulic actuators and include said brackets, said bottom side arms, braces and said top side arm, which make up a rigid set with the alternator axis; and wherein the damping bearings are supported by internal walls of the bearing brackets against the internal braces.
