Coaxial Motor Arrangement for Vehicle Roll Stabilization and Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll stabilization and steering systems for double-track motor vehicles lack a compact and efficient arrangement that optimizes space usage and provides adequate support during vehicle assembly and potential crashes.
Innovation Solution
A roll stabilization system with a split lateral stabilizer and a steering system where the gear is arranged coaxially between the stabilizer halves, with motors positioned to introduce stabilization and steering torques, allowing for a compact configuration and shared motor design, and integrated into the axle carrier for enhanced support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the roll stabilization motor and steering motor are arranged separately in the vehicle, then each system can be independently maintained and adjusted, but the available space is wasted and the overall structure lacks compactness
Solution Approach 1:
The patent combines the roll stabilization motor and steering motor into a single common mounting location on the axle carrier. Both motors share the same mounting structure and spatial arrangement, allowing them to be integrated into the vehicle's front axle assembly without interfering with each other's function or maintenance requirements.
Solution Approach 2:
The axle carrier is designed with a universal mounting structure that can accommodate both the roll stabilization motor and steering motor. This multi-functional mounting arrangement allows the same structural elements to support multiple systems, optimizing space utilization while maintaining independent functionality of each system.
2Strength
If the axle carrier is designed to provide structural reinforcement, then crash resistance is improved, but the weight of the vehicle increases
Solution Approach 1:
The patent integrates the structural reinforcement function into the existing axle carrier structure by adding mounting elements for the motors. Rather than adding separate reinforcement structures, the axle carrier itself is designed to provide both motor mounting and structural support during crashes, combining multiple functions into a single component.
Solution Approach 2:
The axle carrier serves multiple functions: it supports the wheel assembly, provides mounting locations for both motors, and acts as a structural reinforcement element during crashes. This multi-functional design provides crash resistance without requiring additional dedicated reinforcement components that would increase weight.
3Ease of manufacture
If identical motors are used for both roll stabilization and steering systems, then manufacturing costs and maintenance complexity are reduced, but the torque requirements and performance specifications become more difficult to meet
Solution Approach 1:
The patent specifies that identical electric motors with essentially coinciding axes of rotation are used for both the roll stabilization system and steering system. These universal motors are mounted on the axle carrier and can perform either function depending on system requirements, simplifying manufacturing and maintenance while meeting performance demands through proper motor selection.

AI summary
An arrangement of a roll stabilization system equipped with a split lateral stabilizer and an arrangement of a steering system on a double track motor vehicle is provided. A gear of the roll stabilization system is arranged essentially coaxially between two halves of the lateral stabilizer rotatable with respect to one another, and a motor for introducing a stabilization torque is arranged at the side of this gear and the lateral stabilizer. The steering system has, in addition to a steering gear, with which steering arms can be moved essentially in the transverse direction of the vehicle, a motor, which is arranged at the side of the steering gear and a movement axis defined by the movable steering arms. The motor of the roll stabilization system and the motor of the steering system lie in essence one behind the other, as viewed in the transverse direction of the vehicle, and may preferably be electric motors with essentially coinciding axes of rotation that run in the transverse direction of the vehicle and are arranged inside an axle carrier so as to lie essentially in the plane thereof.
