Work Vehicle Stabilizer Placement and Transmission Case Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle configurations face challenges in efficiently positioning a stabilizer and protecting the transmission case when it is arranged at the rear end of the vehicle body frame, leading to increased assembly time and potential interference with other components.
Innovation Solution
A configuration where a guard member is placed rearward of the transmission case and the stabilizer is positioned forward of the guard member, allowing for easy placement and protection of the transmission case, with the stabilizer supported by suspension arms and holders that enable rotational stability and elastic deformation to manage rear wheel movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the transmission case is arranged at a rear position of the vehicle body frame, then the driving force transmission to rear wheels is improved, but the stabilizer placement becomes difficult and assembly time increases
Solution Approach 1:
The patent resolves the spatial conflict by utilizing the vertical dimension - placing the stabilizer above the transmission case rather than in the horizontal space behind it. The stabilizer is positioned in the upper rear portion of the vehicle body, while the transmission case occupies the lower rear portion, thereby eliminating interference and simplifying assembly.
2Length of moving object
If the vehicle body frame length is shortened to reduce weight and size, then the vehicle compactness is improved, but the transmission case protrudes backward requiring additional protection
Solution Approach 1:
The guard member serves multiple functions: it protects the protruding transmission case from damage, provides a mounting structure for the stabilizer, and maintains the aesthetic appearance of the vehicle rear. This multi-functional design eliminates the need for separate protective components.
3Ease of operation
If the stabilizer is inserted through a space in the rear portion of the vehicle body, then the stabilizer can be positioned, but the assembly process requires more time and effort
Solution Approach 1:
The patent applies preliminary action by pre-positioning the stabilizer on the upper surface of the vehicle body frame before final assembly. The stabilizer is mounted on a support structure that is already in place, eliminating the need for complex insertion operations and reducing assembly time.

AI summary
A work or utility vehicle utilizing a drive source, a vehicle body frame, left and right front wheels supported on the vehicle body frame and left and right rear wheels supported on the vehicle body frame. A transmission case is supported on the vehicle body frame and transmits a driving force from the drive source to at least the left and right rear wheels. A guard member protects the transmission case. A stabilizer is supported at two ends by suspension arms of the left and right rear wheels. The guard member is arranged on a rear side of the transmission case and the stabilizer is arranged forwardly of the guard member.
