Riding Mower Drive Assembly Layout for Strength and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riding mowers face challenges in providing a simple structure with high structural strength and stability, especially in complex working environments.
Innovation Solution
The riding mower design includes a traveling assembly with symmetrically disposed drive assemblies connected by a connection plate, a power supply apparatus with a detachable battery compartment, and a parking system with a rotation stop mechanism, enhancing structural strength and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the riding mower uses a conventional drive assembly structure, then the device complexity is reduced, but the structural strength and stability deteriorate under complex working terrain
Solution Approach 1:
The drive assembly is divided into first and second drive assemblies disposed symmetrically on either side of the main frame. Each drive assembly is independently connected to the main frame via connectors, allowing separate installation and maintenance while collectively providing enhanced structural strength and stability.
Solution Approach 2:
The first and second drive assemblies are connected to each other through a connection plate, merging them into an integrated unit. This combination strengthens the overall structure by distributing mechanical loads across multiple connection points between the drive assemblies and the main frame.
2Stability of the object's composition
If the riding mower uses a symmetric drive assembly structure connected by a connection plate, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
While the overall structure maintains symmetry for balance, the drive assemblies and their connections are designed to accommodate asymmetric working conditions. The symmetric arrangement provides stability during operation on uneven terrain while allowing independent adjustment of each side if needed.
Solution Approach 2:
The connection plate serves multiple functions: it connects the first and second drive assemblies together, provides mounting points for both assemblies, and reinforces the structural stability of the entire drive system. This multi-functionality reduces the need for additional separate components.
3Ease of repair
If the drive assemblies are independently connected to the main frame, then the ease of repair is improved, but the structural strength deteriorates
Solution Approach 1:
The drive system is segmented into independently connectable first and second drive assemblies, each with its own connection to the main frame. This segmentation allows one assembly to be removed or repaired without affecting the other, facilitating easier maintenance while maintaining structural integrity through the connection plate.

AI summary
A riding mower includes a seat for a user to sit on, a main frame configured to support the seat, a power output assembly configured to mow vegetation, a traveling assembly configured to enable the riding mower to travel, an operating assembly configured to be operated by the user, a control module configured to control the riding mower, and a power supply apparatus configured to supply power to the riding mower. At least a portion of the control module is disposed on the lower side of the seat, and the control module comprises a drive control board for controlling the power output assembly and the traveling assembly, a fuse, and a power supply management module.
