Clutch Release Greasing Pipe Positioning Without Housing Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing greasing maintenance for clutch release mechanisms requires detaching and reattaching the clutch housing, which is inefficient and prone to damage from foreign objects like sand and muddy water, reducing work efficiency.
Innovation Solution
A greasing device with a greasing pipe and positioning part that extends through a through-hole in the clutch housing to feed grease to the contact portion between the clutch release fork and release bearing, allowing for greasing without removing the clutch housing, using a first and second jig to position the pipe accurately and avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clutch housing is detached and reattached for greasing maintenance, then the contact portion can be accessed for grease application, but the work efficiency decreases and the risk of damage from foreign objects increases
Solution Approach 1:
The greasing device is divided into separate components: a positioning part that attaches to the clutch housing, and a greasing pipe that can be inserted through the through-hole. This segmentation allows the positioning part to remain attached while the greasing pipe is temporarily inserted and removed, enabling maintenance without full disassembly.
Solution Approach 2:
The greasing pipe acts as an intermediary tool that passes through the through-hole in the clutch housing to deliver grease to the contact portion. This intermediary approach allows grease application without requiring removal of the clutch housing, thus maintaining work efficiency while achieving the greasing objective.
2Ease of operation
If the clutch housing is removed for greasing maintenance, then the contact portion becomes accessible, but the time required for maintenance increases
Solution Approach 1:
The positioning part is pre-equipped with positioning holes and the greasing pipe has corresponding positioning protrusions that align with these holes. This preliminary positioning arrangement ensures that when the greasing pipe is inserted, it automatically reaches the correct position at the contact portion, eliminating the need for time-consuming manual positioning and trial-and-error adjustments.
3Device complexity
If a simple greasing pipe is used without positioning features, then the device complexity is reduced, but the greasing precision and ability to avoid obstacles deteriorates
Solution Approach 1:
The positioning part features asymmetric positioning holes at specific locations, and the greasing pipe has corresponding asymmetric positioning protrusions. This asymmetric design ensures that the greasing pipe can only be inserted in the correct orientation and position, guaranteeing precise grease delivery to the contact portion while avoiding obstacles like the release bearing. The asymmetry prevents incorrect insertion and ensures manufacturing precision without requiring complex adjustment mechanisms.

AI summary
A greasing device for feeding grease to a greasing requiring part accommodated inside a housing, the greasing device including: a first jig; a second jig; and a greasing portion, wherein the first jig has a base portion that abuts on the housing, and an insertion hole that penetrates the base portion, the second jig has an insertion portion that is inserted into the insertion hole of the first jig, and a stopper portion that comes into abutment on the base portion of the first jig when the insertion portion is inserted into the insertion hole, and the greasing portion feeds grease to the greasing requiring part while being positioned by the first jig and the second jig.
