Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic servos for gear changes are complex and costly to produce due to the need for numerous holes and ball plugs for fluid-tight sealing, making them difficult to dismantle, clean, and replace.
Innovation Solution
A compact hydraulic servo design featuring a supporting body that houses solenoid valves with simplified internal hydraulic circuits, using a limited number of holes and ball plugs, and incorporating a recovery channel to prevent fluid leakage, allowing for easy disassembly and production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a supporting body with numerous holes and ball plugs is used to house solenoid valves and hydraulic circuits, then fluid-tight sealing is achieved, but manufacturing complexity and production cost increase significantly
Solution Approach 1:
The supporting body is divided into multiple segments or sections, each with its own sealing system. This segmentation allows for simpler individual sealing structures that can be manufactured more easily while collectively providing comprehensive fluid-tight sealing for all hydraulic circuits and solenoid valves.
Solution Approach 2:
Instead of relying solely on multiple ball plugs inserted through holes in the supporting body, the invention introduces a sealing arrangement that extends in a different dimension or orientation. This could involve sealing elements positioned in grooves, channels, or surfaces that provide fluid-tight sealing without requiring numerous through-holes and ball plugs.

AI summary
Described herein is a hydraulic servo for a gear change provided with a control shaft; the servo has: a frame; a first hydraulic actuator, which is carried by the frame and has two first chambers, which are alternatively filled with a pressurized fluid for displacing the control shaft axially in the two directions; two first solenoid valves, which control filling of the two first chambers; a second hydraulic actuator, which is carried by the frame and has at least one second chamber that is filled with a pressurized fluid for rotating the control shaft about its central axis; a second solenoid valve, which controls filling of the second chamber; and a supporting body, which is fixed to the frame, houses the solenoid valves, and has inside it a series of hydraulic circuits, which connect the solenoid valves themselves both to the chambers of the actuators and to a supply of the pressurized fluid.
