Vehicle Suspension Height Adjustment via Dual Tank Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspension systems for vehicles take a long time to adjust vehicle height when lowering, as they alternately lower the height on the front and rear wheel sides simultaneously.
Innovation Solution
The system includes a front wheel-side and rear wheel-side suspension with separate hydraulic fluid tanks, where one side discharges fluid to a low-pressure tank and the other side to a high-pressure tank, allowing simultaneous and rapid height adjustment by controlling the fluid flow through a pressurization device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the suspension system uses a single tank and alternately lowers the vehicle height on front and rear wheel sides, then the system structure is simple, but the vehicle height adjustment time is long
Solution Approach 1:
The single tank is segmented into two separate tanks (first tank and second tank). The front wheel-side suspension discharges hydraulic fluid to the first tank, while the rear wheel-side suspension discharges hydraulic fluid to the second tank. This segmentation allows both sides to operate simultaneously without interfering with each other, resolving the time loss caused by alternating operation while maintaining manageable system complexity through modular tank design.
2Productivity
If the suspension system uses two tanks to simultaneously lower the vehicle height on front and rear wheel sides, then the vehicle height adjustment speed is fast, but the system complexity increases
Solution Approach 1:
The system is segmented into two independent discharge paths: front wheel-side suspension to first tank, and rear wheel-side suspension to second tank. Each path operates independently with its own tank, allowing simultaneous operation that doubles the productivity of vehicle height adjustment. The segmentation maintains simplicity by creating two identical, manageable subsystems rather than one complex integrated system.
Solution Approach 2:
The first tank and second tank act as intermediaries that receive hydraulic fluid from the front and rear wheel-side suspensions respectively. These intermediary tanks buffer the hydraulic fluid discharge, allowing both suspensions to lower the vehicle height simultaneously without direct interference. The intermediary tanks simplify the overall system by providing dedicated reception points for each suspension's discharged fluid.
3Device complexity
If the front and rear wheel sides share the same hydraulic fluid discharge path, then the system structure is simple, but the vehicle height adjustment time increases due to interference
Solution Approach 1:
The shared hydraulic fluid discharge path is segmented into two separate discharge paths. The front wheel-side suspension has its own discharge path to the first tank, and the rear wheel-side suspension has its own discharge path to the second tank. This segmentation eliminates interference between front and rear operations, allowing simultaneous vehicle height adjustment without the time loss that occurs when sharing a common discharge path.
Solution Approach 2:
The first tank and second tank serve as intermediary receptacles that receive hydraulic fluid from the front and rear wheel-side suspensions through separate discharge paths. These intermediary tanks prevent interference by providing dedicated reception points, allowing both suspensions to discharge hydraulic fluid simultaneously without conflict. The intermediary tanks maintain system simplicity by creating independent, non-interfering discharge routes.

AI summary
The present invention provides a suspension system capable of adjusting a vehicle height in a short time. The suspension system includes a front wheel-side suspension and a rear wheel-side suspension each provided between a vehicle body and an axle and configured to adjust a vehicle height according to supply and discharge of hydraulic fluid, a pressurization device configured to pressurize the hydraulic fluid, and a first tank and a second tank configured to store therein the hydraulic fluid pressurized by the pressurization device. When the suspension system lowers the vehicle height by each of the front wheel-side suspension and the rear wheel-side suspension, any one of the front wheel-side suspension and the rear wheel-side suspension discharges the hydraulic fluid to the first tank, and the other of the front wheel-side suspension and the rear wheel-side suspension discharges the hydraulic fluid into the second tank by the pressurization device.
