Content
With advantages of high efficiency and low cost, AMT (Automated Manual Transmission) has a very potential for auto-transmission, especially for heavy commercial vehicle, which has special requirements on low cost and easier operating. Recent years, some developments on multi-speed and electronic control, give us more confidence to consider AMT for heavy commercial vehicles, which offers a convenient and low cost way to multi-speed, and existed abundant gas resource for providing driven power.
On the other hand, some technique issues challenge AMT in the application widely. For example, It is difficult to realize servo control for compressibility of gas. It therefore needs to find a way to realize the accurate control on auto-clutch operation system based on high quality system response. Accordingly, this work presents a system to realize hydraulic control powered with pneumatic power resource. The designed system fulfills high-precision control with fast response advantage of the hydraulic system, as well low-cost and convenient resources from the pneumatic system.
