Modular Attachment Frame with Independent Bearing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment frames for commercial vehicles are complex and require specific adjustment or movement mechanisms, limiting their versatility and efficiency in supporting multiple working devices without additional relief or ground adaptation issues.
Innovation Solution
A modular attachment frame with a rigidly coupled frame base and adjustable bearing means allows for independent positioning of working devices relative to each other and the frame base, enabling efficient operation on various vehicles without additional movement controls, and incorporating energy-saving and cost-effective adjustment drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame base is firmly coupled to the commercial vehicle, then the attachment frame can be used on vehicles without adjustment mechanisms, but the working devices cannot be adjusted relative to the vehicle
Solution Approach 1:
The system segments the adjustment function from the frame base to individual bearing means. Each bearing means can be adjusted independently via adjusting means (hydraulic cylinders), allowing implement positioning without moving the entire frame base. This enables firm vehicle coupling while maintaining operational flexibility.
Solution Approach 2:
The bearing means are designed with adjustable pivot positions relative to the frame base. The adjusting means enable dynamic repositioning of bearing means during operation, allowing the implements to be adapted to different working conditions while the frame base remains firmly coupled to the vehicle.
2Ease of operation
If adjustment mechanisms are added to the vehicle, then working devices can be positioned, but the device complexity increases
Solution Approach 1:
The adjustment mechanisms are extracted from the vehicle and integrated into the attachment frame itself. The adjusting means are mounted on the frame base and act on the bearing means, transferring the complexity from the vehicle side to the attachment frame side, thereby simplifying the vehicle design.
Solution Approach 2:
The adjusting means serve multiple functions: they adjust the pivot position of bearing means, control implement positioning, and enable adaptation to different working conditions. This multi-functionality reduces the need for separate adjustment mechanisms on the vehicle.
3Strength
If the attachment frame supports working devices, then the devices can be mounted, but the weight affects ground adaptation
Solution Approach 1:
The frame base and vehicle structure support the weight of the attachment frame and implements. The bearing means are designed to bear the loads while maintaining proper ground contact. The system distributes weights appropriately to ensure the implements can adapt to the ground without being impaired by excessive weight.

AI summary
The invention relates to a mounting frame (4) for coupling to a commercial vehicle (1). The mounting frame (4) has a frame base (8). Bearing means (13, 14, 26) are pivotably arranged on the frame base (8) for supporting at least two work tools (9, 10, 11). Adjustment means (29) are provided for adjusting a pivot position of the bearing means (13, 14, 26) such that the pivot positions of the bearing means (13, 14, 26), which are assigned to different work tools (9, 10, 11), are adjustable relative to each other and independently relative to the frame base (8).
