Abstract
For the throttle bodies for sport motorcycles, there is a need for a design giving importance to drivability and precise control. At the same time, various devices such as idle control and duct control are necessary in order to conform to recent environmental regulations.
However, these added functions lead to an increase in the number of components, thus leading to disadvantages in both cost and weight. Therefore we have developed a throttle body where DBW (Drive By Wire) has been used to consolidate such parts, and functions. For the drive actuator, a modified actuator device from a passenger car DBW system was incorporated into a multi-cylinder link structure. In addition, specifications such as the gear ratios and the operation torque were optimized in order to satisfy the operability required for motorcycles.
In this way, we have consolidated all functions that were conducted by separate devices into the throttle valve control system without limiting drivability or control functions.
