Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skid steer loaders face challenges with difficult disassembly and maintenance due to their compact structure and integrated components, which limits their working efficiency and loading capabilities.
Innovation Solution
The design includes a chassis frame with a telescopic cab support, a four-bar linkage mechanism for the main beam and bucket, and detachable fuel and hydraulic oil tanks, allowing for improved inspection and maintenance access and enhanced lifting capabilities through a vertical lifting path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cab, power system, walking system, and electro-hydraulic control system are all integrated and assembled to the chassis frame, then the structure becomes very compact, but disassembly and maintenance become difficult
Solution Approach 1:
The chassis frame is divided into multiple sections with detachable connections. The power system can be separated from the chassis frame through detachable connections, allowing maintenance personnel to access and service components without disassembling the entire integrated structure. This segmentation maintains compactness during operation while enabling easy maintenance when needed.
2Volume of moving object
If the components are assembled inside the loader in a compact arrangement, then the structure becomes very compact, but the fields of view of the components are limited
Solution Approach 1:
The chassis frame incorporates detachable connections that allow dynamic reconfiguration. During normal operation, the structure remains compact with all components integrated. During maintenance, the power system and other components can be detached and repositioned to provide adequate inspection space and access, transforming the static compact structure into a dynamic configuration that adapts to maintenance needs.
3Area of stationary object
If the telescopic support rod is extended to make the cab overturn forward, then the inspection space between the cab and power system is expanded, but the cab structure becomes more complex
Solution Approach 1:
The telescopic support rod provides just enough extension to enable the cab to overturn forward and create inspection space. The rod is designed with a specific stroke that is sufficient for maintenance access but not excessive, balancing the need for inspection space with the desire to keep the cab structure relatively simple. The support rod retracts when not in use, minimizing its impact on the overall cab structure.

Function Achieved in This Case
This design enhances maintenance convenience, increases loading and unloading efficiency, and provides a more compact structure with improved lifting dynamics and safety features, such as the main beam safety rod and cab safety rod, while reducing the size of hydraulic cylinders required.
Implementation Method 1
the other side of the bottom of the cab is supported and connected to the chassis frame 1 at a position other than the hinged position by a telescopic support rod 26
Implementation Method 2
a tail end of the main beam 3 is movably hinged to the tail portion of the chassis frame 1 by a four-bar linkage mechanism 31
Implementation Method 3
a lifting oil cylinder 52 for driving the main beam to swing up and down to lift and lower the bucket is assembled between the main beam 3 and the chassis frame 1

AI summary
A skid steer loader includes a chassis frame, a cab, a main beam, and a bucket. The chassis frame is assembled with a walking system to form a movable chassis of the skid steer loader, and a power system of the skid steer loader is assembled to a tail portion of the chassis frame. The cab is arranged on a front portion of the chassis frame in an. overturning manner, and the cab is horizontally placed on the chassis frame when a telescopic support rod is in a retracted state and overturns forward when the telescopic support rod is in an extended state. A tail end of the main beam is movably hinged to the tail portion of the chassis frame by a four-bar linkage mechanism, the bucket is assembled to a front end of the main beam.
