A Study On The Main Parameter Derivation For Influences On Foot Effort Characteristics In Commercial Vehicles

상용차량 클러치 페달 답력 특성에 영향을 미치는 주요 인자 도출에 관한 연구

For commercial vehicles with a manual transmission, the pneumatic and fluid pressure servo-device is widely used for transmitting large torque. However, the pneumatic and fluid pressure servo-device usually results in non-linear variation of foot-efforts, also such characteristics tend to increase physical fatigue of drivers who drive commercial vehicles for a long time. Thus, vehicle manufacturers consider the hysteresis loops in the Clutch Actuation System (CAS) design when a new vehicle model is being developed. In this study, we numerically simulate the hysteresis loops for predictable CAS design, and the experimental results confirm the simulation results.
