Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vehicles require complex differential mechanisms to manage speed differences between internal and external wheels during steering, leading to complicated mechanical structures and manufacturing challenges.
Innovation Solution
A synchronous steering vehicle body design that synchronizes the rotation of wheels and the cab without a differential mechanism, using a steering mechanism comprising a driving device, rotary execution mechanisms, and a transfer device to ensure consistent rotational directions and speeds, maintaining rectilinear motion during steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a differential mechanism is used to regulate the revolution speed difference of internal and external wheels during steering, then the vehicle can maintain balance during steering, but the mechanical structure becomes complicated with many parts
Solution Approach 1:
The patent extracts and removes the differential mechanism from the vehicle steering system, replacing it with a synchronous steering mechanism where the cab itself rotates to achieve steering. This eliminates the complex differential mechanism while maintaining steering functionality through a different approach - the entire cab body rotates about a vertical axis rather than relying on differential wheel rotation.
Solution Approach 2:
Instead of allowing the wheels to rotate at different speeds (traditional differential steering), the patent inverts the approach by rotating the entire cab body synchronously. The steering is achieved by rotating the cab about a vertical axis, which causes all wheels to rotate synchronously in the same direction, eliminating the need for speed differential regulation.
2Reliability
If a differential mechanism is used to manage speed differences between internal and external wheels, then steering balance is maintained, but manufacturing becomes more challenging
Solution Approach 1:
The patent removes the differential mechanism entirely from the vehicle design, replacing it with a synchronous steering system where the cab body itself rotates. This simplification directly improves ease of manufacture by eliminating complex differential components that are difficult and costly to manufacture and assemble.
Solution Approach 2:
The patent merges the steering function with the cab body structure itself. The cab body serves dual purposes: as the passenger compartment and as the rotating steering mechanism. This integration eliminates the need for separate differential mechanisms and simplifies the overall manufacturing process.
3Ease of operation
If traditional steering mechanism is used, then wheels can turn, but the vehicle body undergoes circular motion which affects stability
Solution Approach 1:
Instead of allowing the vehicle body to undergo circular motion during steering (traditional method), the patent inverts the approach by rotating the entire cab body synchronously about a vertical axis. This inversion maintains the vehicle body's orientation relative to the ground while achieving steering through cab rotation, thereby maintaining stability during steering operations.
Solution Approach 2:
The patent applies preliminary action by rotating the cab body in advance before the wheels need to turn. The synchronous rotation of the cab body prepares the vehicle for directional change, allowing the wheels to follow the predetermined rotation path without causing circular motion of the vehicle body, thus maintaining stability.

AI summary
A synchronous steering vehicle body includes wheels, a cab and a steering mechanism for driving the wheels and the cab to synchronously steer, steering center axes of the wheels are vertical to rotation center axes of the wheels, and the wheels are vertical to the center of the horizontal ground to be concentric to the steering center axes of the wheels, and the steering motions of the wheels and the cab are kept synchronous. The disclosure provides a synchronous steering vehicle body capable of directly achieving the synchronous steering of the wheels and the cab.
