Abstract
A vehicle subassembly includes first and second hydraulic cylinders each having an upper chamber and a lower chamber. A fluid circuit is hydraulically connected to the first and second hydraulic cylinders and includes a valve movable between a first position where the upper chamber of the first hydraulic cylinder and the lower chamber of the second hydraulic cylinder are hydraulically connected and the lower chamber of the first hydraulic cylinder and the upper chamber of the second cylinder are hydraulically connected, and a second position where the upper chamber and the lower chamber of the first hydraulic cylinder are hydraulically connected and the upper chamber and lower chamber of the second hydraulic cylinder are hydraulically connected. A control unit is operable to position the valve in at least one of the first position and the second position based on an operating variable of the vehicle.

7. A subassembly for a vehicle, the subassembly comprising:
-
a first hydraulic cylinder having an upper chamber and a lower chamber; a second hydraulic cylinder having an upper chamber and a lower chamber; a fluid circuit hydraulically coupled to the first hydraulic cylinder and the second hydraulic cylinder and including a flow control device movable between a first position and a second position, wherein when the flow control device is in the first position the upper chamber of the first hydraulic cylinder is hydraulically coupled to the lower chamber of the second hydraulic cylinder and the lower chamber of the first hydraulic cylinder is hydraulically coupled to the upper chamber of the second cylinder, and wherein when the flow control device is in the second position the upper chamber of the first hydraulic cylinder is hydraulically coupled to the lower chamber of the first hydraulic cylinder and the upper chamber of the second hydraulic cylinder is hydraulically coupled to the lower chamber of the second hydraulic cylinder; a control unit operable to position the flow control device in at least one of the first position and the second position in response to an operating variable of the vehicle. - View Dependent Claims (8, 9, 10, 11, 12, 13)
