Track Loader Suspension Bracket Layout to Prevent Track Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional track loaders face issues where the suspension pressing the upper surface of the side frame interferes with the yoke's movement, leading to incomplete prevention of track sagging.
Innovation Solution
The track loader incorporates a bracket system that mounts the suspension's axle on the undercarriage, ensuring the side frame upper plate is not pressed by the axle, thus preventing interference with the yoke's movement and allowing effective track tension control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the suspension is directly mounted on the side frame, then the structure is simple, but the axle presses the side frame upper plate which interferes with yoke movement and cannot effectively prevent track sagging
Solution Approach 1:
The mounting structure is divided into two separate components: the side frame and the bracket. The bracket is attached to the side frame side plate and extends to support the suspension axle, separating the mounting function from the side frame structure itself. This segmentation allows the yoke to move freely in the side frame upper plate while the bracket handles the suspension mounting, resolving the interference problem and ensuring reliable track sagging prevention.
2Ease of manufacture
If the axle is directly mounted on the side frame upper plate, then the mounting is straightforward, but it presses the yoke and interferes with its reciprocating movement
Solution Approach 1:
Instead of mounting the axle directly on the side frame upper plate (horizontal mounting), the bracket extends in a different dimension (vertically downward from the side frame side plate) to support the axle. This dimensional change relocates the axle mounting position away from the yoke's reciprocating path, eliminating interference while maintaining straightforward mounting through the bracket's attachment to the side frame side plate.
3Stability of the object's composition
If the suspension presses the side frame, then the suspension is stable, but it causes the side frame to deform and interferes with yoke movement
Solution Approach 1:
The bracket acts as an intermediary component between the suspension axle and the side frame. Instead of the axle directly pressing the side frame upper plate, the bracket mediates this interaction by providing a dedicated mounting point on the side frame side plate. This intermediary structure distributes the suspension loads separately from the side frame's primary structural components, maintaining suspension stability while preventing side frame deformation and yoke movement interference.

AI summary
The present disclosure relates to a track loader and may include a carriage on which a driving source and a lift arm that moves a bucket by receiving power from the driving source, an undercarriage for transporting the carriage, a suspension for buffering between the carriage and the undercarriage, and a bracket for mounting the suspension on the undercarriage, wherein the suspension includes a tube fixed to the carriage, a bar inserted into the tube, an elastic member interposed between the tube and the bar, a torsion arm connected to the bar, and an axle connected to the torsion arm, and since the axle is mounted on the bracket, it is possible to reduce an impact transferred from the undercarriage to the carriage while preventing sagging of a track.
