Work Vehicle Front Axle Protruding Part Obstacle Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In work vehicles, the connection member of the power steering cylinder can contact obstacles due to its arrangement below the front axle casing, especially when the support stay is at the same height as the front axle bracket, leading to potential contact with ground obstacles during travel.
Innovation Solution
A protruding part is formed at the lower end of the front axle casing, extending below the support part and positioned to cover the connection member, ensuring it is protected from obstacles by being arranged lower and more forward than the connection member, with a curved or bent shape to effectively prevent contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support stay is arranged at the same height as the front axle bracket to accommodate engine layout, then the power steering cylinder can be installed, but the connection member projects below the front axle casing and may contact ground obstacles during travel
Solution Approach 1:
The invention introduces a new spatial dimension by forming a protruding part that extends in the longitudinal direction (front-rear axis) from the support part. This longitudinal extension creates a protective coverage zone that shields the connection member from obstacles without requiring vertical height adjustment, thus resolving the contradiction between layout adaptability and obstacle contact risk.
Solution Approach 2:
The protruding part acts as an intermediary protective structure between the connection member and ground obstacles. It physically intercepts obstacles before they can contact the connection member, while being integrated into the support part structure. This mediator approach allows the connection member to remain in its original position for layout flexibility while preventing harmful obstacle contact.
2Length of stationary object
If the connection member is arranged below the front axle casing to reduce overall height, then the vehicle profile is lowered, but the connection member becomes vulnerable to ground obstacles
Solution Approach 1:
The protruding part is nested within the support part structure, forming an integrated protective enclosure. The connection member is positioned within the coverage zone created by the protruding part's longitudinal extension. This nested configuration protects the connection member from obstacles while maintaining the compact vertical profile, as the protection is achieved through longitudinal rather than vertical extension.
3Ease of manufacture
If the support part is formed at the lower end of the front axle casing to accommodate connection member positioning, then the connection member can be secured, but it projects below the support part and may contact obstacles
Solution Approach 1:
The protruding part is formed in advance as an integral part of the support part structure, creating a pre-established protective coverage zone. This preliminary action ensures that the connection member, when installed in the support part, is automatically shielded from obstacles without requiring additional protective components or complex assembly steps, thus maintaining ease of manufacture while preventing obstacle contact.

AI summary
Provided is a work vehicle in which a connection member can be prevented from coming into contact with an obstacle while the work vehicle is traveling, without restricting the layout of the work vehicle. A work vehicle 1 in which a power steering cylinder 50 is mounted to a front axle case 30, wherein in the front axle case 30, a support part 30a to which the power steering cylinder 50 is mounted by a connection member 51, and a protruding part 30b that protrudes from the support part 30a so as to conceal the connection member 51 when viewed from the front side of the work vehicle 1 are formed.
