Universal Wishbone Trailing Arm for Off-Road Suspension Challenges
Here’s PatSnap Eureka !
Summary
Problems
Off-road vehicle suspension systems face challenges in mechanical strength and complexity, particularly when navigating rough terrain, as existing systems struggle to maintain wheel tracking and protect critical components from damage.
Innovation solutions
A universal wishbone trailing arm design featuring a wheel hub with roller bearings, swing arms, and articulated mounts that allow for camber angle adjustment and protection of constant velocity joints, while enabling vertical motion absorption and symmetry for interchangeability between sides.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a traditional trailing arm suspension is used, then the structure is simple, but the mechanical strength is insufficient and wheel tracking cannot be maintained over rough terrain
Why choose this principle:
The patent combines multiple functions into a single integrated wishbone trailing arm assembly that includes both swing arms, axle support, and mounting brackets as one unified structure. This merging provides enhanced mechanical strength while maintaining reasonable complexity by consolidating components that work together as a system.
Principle concept:
If a traditional trailing arm suspension is used, then the structure is simple, but the mechanical strength is insufficient and wheel tracking cannot be maintained over rough terrain
Why choose this principle:
The trailing arm is constructed from high-strength steel materials that provide superior mechanical strength and durability. The use of composite or multi-material construction in critical areas allows the structure to withstand rough terrain forces while managing overall system complexity.

Abstract
A universal wishbone trailing arm and methods are provided for coupling a wheel to a vehicle chassis. The universal wishbone trailing arm comprises a wheel hub that fastenably receives the wheel. A cylindrical axle support supports one or more roller bearings whereby the wheel hub is rotatable. A first swing arm and a second swing arm extend forwardly from a joined swing arm. The cylindrical axle support is coupled to a rear of the joined swing arm. A first chassis mount hingedly couples the first swing arm to the vehicle chassis. A second chassis mount hingedly couples the second swing arm to an articulated mount which is configured to couple the second swing arm to the vehicle chassis. The articulated mount cooperates with the first second swing arms to change camber of the wheel, such that a tracking of the wheels remains substantially unchanged during traveling over rough terrain.
