AI Technical Summary
The existing hydraulic mechanical transmissions have limited space for the shift clutches and insufficient spring separation capacity, which cannot meet the requirements for increasing the power density of the transmission.
A rectangular cross-section cylindrical helical compression spring and a limiting mechanism are adopted, combined with multiple high-strength springs and a stop half-ring, to optimize the structure of the clutch cylinder liner and friction plate and enhance the separation capability.
It improves the disengagement capability of the shift clutch within a limited space, avoids the burning problem, and is suitable for the shift clutch of a compact hydraulic mechanical transmission.
