Wheel Hub Adaptor With Bayonet Mounting for Off-Road Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles, especially four-wheel drive vehicles, face traction issues on soft surfaces like sand and deeply rutted tracks, leading to loss of traction and potential stranding, as existing recovery methods focus on external sources or limited improvements to tire grip.
Innovation Solution
A wheel hub adaptor that attaches to vehicle wheels, allowing for the secure fitting of various accessories such as paddles, winches, or additional wheels, which increase traction by rotating with the wheel, using a bayonet-style mounting system to ensure secure attachment and alignment with the wheel's stud pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional external recovery methods (towing, winching) are used, then vehicles can be recovered from stranded positions, but the process requires external equipment and sources, increasing device complexity and time loss
Solution Approach 1:
The invention extracts the recovery function from external sources and integrates it directly into the wheel hub system. The hub adaptor incorporates a built-in winch mechanism and anchor point system, eliminating the need for separate external recovery equipment. This allows the vehicle to perform self-recovery operations using its own wheel rotation power.
Solution Approach 2:
The hub adaptor enables the vehicle to recover itself from stranded positions using its own mechanical power. The system uses the wheel's rotational force to wind the winch cable and pull the vehicle free, eliminating dependency on external recovery vehicles or equipment.
2Reliability
If hub adaptors are designed for secure attachment, then reliability of accessory mounting is improved, but the mounting mechanism complexity increases
Solution Approach 1:
The mounting system is divided into distinct functional elements: the hub adaptor body, the accessory interface, and the locking mechanism. This segmentation allows each component to be optimized independently while maintaining overall simplicity. The bayonet-style mounting separates the attachment function from the securing function, making the system both reliable and simple.
Solution Approach 2:
Instead of using complex multi-step locking mechanisms, the invention employs a bayonet-style mounting where the accessory is inserted and then rotated to lock into place. This reverses the traditional approach of screwing or clamping, providing secure attachment through a simple rotational motion that engages protrusions with corresponding recesses.

AI summary
Wheel hub adaptor (11) attachable to vehicle wheel to attach vehicle accessory for rotation with vehicle wheel, has an inner mounting plate (15) with recesses or apertures (17) to match a vehicle wheel stud pattern, a body (19) extending from the plate (15) to an outer mounting plate (27) having a mount to which the vehicle accessory attaches. The mount has apertures (65) which align with studs (75) on a mating mount of the vehicle accessory. The inner mounting plate and the outer mounting plate mount to the vehicle wheel and vehicle accessory respectively, by rotating apertures (17 65) to stop portions (35 71), and is secured by a bolt passing through one of two circular apertures (43 45) or (67 69). Vehicle accessories can be provided like a paddle to self-propel the vehicle in sand, and a wheel to widen the vehicle track.
