Axle Suspension Transverse Link Lever Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional axle suspensions for agricultural and industrial vehicles with pendulum-mounted, rigid axle bodies often require multiple components and space, increasing installation complexity and costs, while failing to efficiently distribute suspension effects across the vehicle.
Innovation Solution
A suspension device with a transverse link and flexible coupling sites, including damper or spring elements, is placed between the axle body and the vehicle's support structure, allowing for efficient vertical suspension with reduced components and space usage, utilizing a transverse link that acts as a two-armed lever to distribute suspension effects and enable oscillation, potentially omitting hydraulic cylinders on one side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional axle suspension with multiple components (including hydraulic cylinders on both sides) is used, then reliable vertical suspension is achieved, but the number of components increases and space requirements increase
Solution Approach 1:
The patent combines the suspension functions for both sides of the axle into a single suspension device located on one side. The transverse link acts as a two-armed lever that transmits the suspension effect from the single side to both left and right sides of the axle, thereby merging multiple suspension functions into one component and eliminating the need for separate hydraulic cylinders on each side.
Solution Approach 2:
The transverse link serves multiple functions: it provides lateral support for the axle body, enables pendulum oscillation, transmits suspension effects bidirectionally through its two-armed lever action, and connects the single-sided suspension device to both sides of the axle. This multi-functionality replaces what would traditionally require multiple separate components.
2Reliability
If conventional axle suspension components are used, then sufficient suspension coverage is achieved, but space requirements increase and installation flexibility decreases
Solution Approach 1:
The patent transitions from a symmetric bilateral suspension arrangement to an asymmetric single-sided arrangement. By positioning the suspension device on only one side and using the transverse link's lever action to distribute forces, the design exploits the transverse dimension differently, achieving full suspension coverage with reduced spatial footprint and improved installation flexibility.
3Ease of operation
If multiple hydraulic cylinders are used on both sides, then comprehensive suspension control is achieved, but installation costs and complexity increase
Solution Approach 1:
The patent extracts and eliminates the redundant hydraulic cylinder from one side of the suspension system. By retaining only the necessary suspension components on one side and using the mechanical lever action of the transverse link to provide suspension control on both sides, the design reduces component count, lowers manufacturing costs, and simplifies installation while maintaining comprehensive suspension control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the number of necessary components, minimizes space requirements, lowers installation costs, and enhances space flexibility for other components, while providing effective vertical suspension and oscillation support with a low-cost, space-saving design.
Implementation Method 1
This suspension device contains, for example, a damper element or a spring element for the damping of vertical forces acting on the vehicle
Implementation Method 2
This suspension device contains, for example, a damper element or a spring element for the damping of vertical forces acting on the vehicle
Implementation Method 3
Thus, the transverse link acts as a two-armed lever with respect to the pendulum support or the second link area. In this way, an effect of the suspension device (for example, a spring or damping effect height) can be introduced both on the third link area as well as on the first link area of the transverse link
Implementation Method 4
The transverse link is linked to the axle body with a second link area via a pendulum support. In this way, the transverse link provides a lateral support for the axle body and allows the axle body to swing or oscillate with respect to the pendulum support

AI summary
A vehicle includes a support structure and a suspension for an oscillatingly supported, rigid axle body. The suspension has a suspension device which is located between the axle body and the support structure and acts in a height direction of the vehicle. The vehicle further includes a plurality of coupling sites and a transverse link extending in a transverse direction of the vehicle. The transverse link is coupled to the support structure via a first link area and via a second link area and a pendulum support to the axle body. The transverse link includes a third link area which, with reference to the pendulum support in the transverse direction of the vehicle, is located opposite the first link area and is flexibly connected with a coupling site of the suspension device.
