Motorcycle Clutch Hydraulic Layout for Faster Shift Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing semi-automatic transmission systems in saddle-riding type vehicles face challenges in achieving responsive oil pressure control for the clutch, leading to delayed transmission operations and inefficient energy management.
Innovation Solution
The configuration of the saddle-riding type vehicle includes an oil pressure actuator and oil pressure valve unit arranged on opposite sides of the vehicle width direction, with the slave cylinder and oil pressure valve unit on one side and the oil pressure actuator on another, allowing for closer proximity and quicker oil pressure transmission, enhancing responsiveness and maintaining weight balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the oil pressure actuator and oil pressure valve unit are arranged close to each other, then the oil pressure control responsiveness is improved, but the weight balance of the vehicle deteriorates
Solution Approach 1:
The patent divides the oil pressure control system into two separate functional units: the oil pressure actuator (master cylinder) and the oil pressure valve unit. These units are positioned at different locations - the actuator on one side of the vehicle and the valve unit on the other side - allowing the system to achieve both rapid oil pressure control through direct connection and proper weight distribution across the vehicle chassis.
2Speed
If the connection pipe length is shortened, then the oil pressure transmission speed is improved, but the device complexity increases
Solution Approach 1:
The patent resolves the connection pipe length issue by utilizing the vehicle width dimension. Instead of positioning components along the longitudinal axis, the oil pressure actuator and valve unit are arranged on opposite sides of the vehicle, allowing for a direct, short connection path that minimizes oil pressure transmission delay while avoiding complex routing through the vehicle's longitudinal space.
3Stability of the object's composition
If the oil pressure actuator is positioned on one side and the valve unit on the other, then the weight balance is improved, but the oil pressure control responsiveness deteriorates
Solution Approach 1:

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration shortens the connection pipe length, enhances oil pressure control responsiveness, and maintains weight balance by distributing the oil pressure actuator and valve unit across the vehicle width, preventing transmission projection and protecting components from external disturbances.
Implementation Method 1
an oil pressure generator that generates an oil pressure (hydraulic pressure) on an operation oil
