Hydraulic system of an active chassis of a motor vehicle

A hydraulic system for an active chassis of a motor vehicle

• having a plurality of hydraulic actuators, said hydraulic system comprising:
• a plurality of hydraulic lines,
• a hydraulic accumulator having an accumulator body that extends along a longitudinal axis,
• an electro-hydraulic motor pump unit that is configured to convey a hydraulic fluid through the hydraulic lines during operation of the hydraulic system,
• a plurality of valves associated with the hydraulic actuators, and
• a cooling apparatus having:
• (a) a cooling body that (i) extends along the longitudinal axis, (ii) includes a first side that is attached to a lower surface of the hydraulic accumulator such that the cooling body extends to an elevation beneath the accumulator body of the hydraulic accumulator, (iii) includes a second side that is opposite the first side, and (iv) includes heat exchange fins extending transversely from the longitudinal axis, and
• (b) a cooler extension extending from the cooling body for connection to a body of the motor vehicle,
• wherein the hydraulic system is configured to electronically control a selective filling of the hydraulic actuators with the hydraulic fluid.
