Vehicle Height Adjustment with Single-Handle Hydraulic Balancing

The patent merges multiple operating portions into a single operating portion that controls multiple pistons simultaneously. The operating portion is configured to move along the cylindrical body's axis, and through mechanical coupling (such as a rod connecting both pistons), it ensures that both pistons move by the same amount, thereby achieving uniform oil flow to both damper devices with a single operation.

The single operating portion serves multiple functions: it controls both pistons, ensures equal movement of both pistons, and thereby regulates oil flow to both damper devices uniformly. This multi-functional design eliminates the need for separate operating portions for each damper device while maintaining adjustment uniformity.

By combining the control of multiple pistons into a single operating portion, the patent enables simultaneous adjustment of both damper devices. When the operating portion moves along the cylindrical body, it drives both pistons at the same time, ensuring consistent oil flow and height adjustment across both sides, thereby reducing the total adjustment time while maintaining consistency.

The single operating portion enables continuous and simultaneous action on both pistons during the adjustment process. As the operator moves the operating portion along the cylindrical body, both pistons are driven continuously and uniformly, ensuring that oil flows uniformly to both damper devices in a single continuous operation, thus reducing adjustment time while maintaining consistency.

The patent employs asymmetric mechanical coupling between the operating portion and the pistons. The operating portion is positioned asymmetrically relative to the pistons, and the coupling mechanism (such as a connecting rod) is designed to transmit motion asymmetrically, ensuring that both pistons receive equal movement forces simultaneously. This asymmetric design allows the single operating portion to maintain precise control over both pistons, ensuring uniform movement while improving productivity.

The patent introduces an intermediary mechanical coupling mechanism (such as a rod or connecting structure) between the single operating portion and the multiple pistons. This intermediary ensures that the motion from the single operating portion is evenly distributed to both pistons, maintaining uniform piston movement while enabling simultaneous control, thus achieving both high productivity and precision.

The patent segments the cylindrical body into multiple oil chambers, with each chamber housing a piston. This segmentation allows independent control of oil flow to each damper device while maintaining uniform distribution. The partitioning creates distinct spaces for oil circulation, enabling precise control over oil flow to each side of the vehicle, thereby improving uniformity of oil distribution despite the increased structural complexity.

The patent employs a nested structure where pistons are positioned inside the partitioned oil chambers within the cylindrical body. Each piston is nested within its respective oil chamber, and the entire assembly is integrated into the cylindrical body. This nested design allows for compact arrangement of multiple components, managing structural complexity while enabling uniform oil distribution through the partitioned chambers.
