Vehicle With Bearing-Mounted Pantograph Support Structure

A vehicle comprising:

• a chassis;
• an electric motor;
• a pantograph support structure mounted to the chassis;
• and
• a pantograph mounted on the pantograph support structure and in electrical communication with the electric motor, wherein the pantograph is movable relative to the pantograph support structure between a stowed position in which the pantograph is spaced apart from overhead electrical wires and a deployed position in which the pantograph is in contact with the overhead electrical wires, and wherein the pantograph is movable between the stowed and deployed positions without corresponding movement of the pantograph support structure;
• wherein the pantograph support structure includes:
• a first leg frame having a lower end attached to the chassis;
• a second leg frame having a lower end attached to the chassis;
• a first bearing mount assembly attached to the lower end of the first leg frame and connecting the first leg frame to the chassis, wherein the first bearing mount assembly includes a first bearing assembly;
• and
• a second bearing mount assembly attached to the lower end of the second leg frame and connecting the second leg frame to the chassis, wherein the second bearing mount assembly includes a second bearing assembly.
