Driving Arrangement For Construction Machine

Abstract

The present disclosure relates to a driving arrangement for a construction machine, such as an excavator, comprising a hydraulic pump for powering a working equipment and/or locomotion of the construction machine through a hydraulic circuit, an electric motor for driving the hydraulic pump, wherein power of the electric motor is transferable to the hydraulic pump via a connection means, a supporting device for mounting the driving arrangement to the construction machine, the supporting device supporting the hydraulic pump and the electric motor, and an adjustment mechanism for adjusting the positional relationship between the electric motor and the hydraulic pump to align both component with respect to each other.

1 . A driving arrangement for a construction machine, comprising:
 a hydraulic pump for powering a working equipment and/or locomotion of the construction machine through a hydraulic circuit;   an electric motor for driving the hydraulic pump, wherein power of the electric motor is transferable to the hydraulic pump via a connection means;   a supporting device for mounting the driving arrangement to the construction machine, the supporting device supporting the hydraulic pump and the electric motor; and   an adjustment mechanism for adjusting the positional relationship between the electric motor and the hydraulic pump to align the electric motor and the hydraulic pump with respect to each other.   
     
     
         2 . The driving arrangement according to  claim 1 , wherein the connection means is configured as an elastic coupling. 
     
     
         3 . The driving arrangement according to  claim 1 , wherein the adjustment mechanism allows for an adjustment of the positional relationship in two different directions, and wherein the two different directions are orthogonal to each other and/or correspond to the vertical and depth directions of the driving arrangement. 
     
     
         4 . The driving arrangement according to  claim 1 , wherein the supporting device comprises a base portion for mounting the driving arrangement to the construction machine, and wherein one of the hydraulic pump and the electric motor is displaceable with respect to the base portion via the adjustment mechanism and the other is stationary with respect to the base portion. 
     
     
         5 . The driving arrangement according to  claim 4 , wherein the supporting device comprises a mounting portion to which the displaceable one of the hydraulic pump and the electric motor is mounted, the mounting portion being connected to the base portion via an adjustment screw for adjusting the positional relationship between the mounting portion and the base portion. 
     
     
         6 . The driving arrangement according to  claim 3 , wherein the mounting portion is connected to the base portion via a vertical adjustment screw for adjusting the vertical positions and a horizontal adjustment screw for adjusting the horizontal positions of the hydraulic pump and the electric motor with respect to each other. 
     
     
         7 . The driving arrangement according to  claim 5 , wherein the supporting device comprises two of the mounting portions, and wherein the two mounting portions are provided on opposite sides of the displaceable one of the hydraulic pump and the electric motor. 
     
     
         8 . The driving arrangement according to  claim 4 , wherein the supporting device comprises a pump mounting portion at one of the ends of the base portion, wherein the electric motor is displaceable above the base portion, and wherein the hydraulic pump is mounted to the pump mounting portion to extend away from the base portion. 
     
     
         9 . The driving arrangement according to  claim 1 , further comprising a damping device provided at the supporting device for mounting the driving arrangement to the construction machine via the damping device. 
     
     
         10 . A construction machine, comprising a driving arrangement according to  claim 1 . 
     
     
         11 . The driving arrangement according to  claim 1 , wherein the construction machine is an excavator. 
     
     
         12 . The construction machine according to  claim 10 , wherein the construction machine is an excavator.
