CruiseActuator

Project: Custom Inline Motorized Cruise Control Actuator Assembly for Motorcycle Throttle General Specifications: Assembly Type: Multi-part mechanical assembly inside a weather-sealed enclosure. Overall Enclosure Dimensions: Rectangular box, approximately 110\text{ mm} length \times 50\text{ mm} width \times 40\text{ mm} height. Material: 7075 Anodized Aluminum for the housing and internal structural brackets. Component Breakdown & Layout: 1. Housing (Enclosure): Two-part clamshell design (Upper and Lower housing halves) secured with corner hex bolts. Machined entry and exit ports on opposite ends equipped with threaded fittings for Bowden cable sheaths. 2. Internal Drive Train & Motor: Geared DC Servo Motor: Cylindrical motor body with an integrated planetary gearbox (approx. 36\text{ mm} diameter \times 65\text{ mm} length) mounted securely in the lower housing. Electromagnetic Clutch: A miniature 12V electromagnetic dog/friction clutch aligned inline between the motor output shaft and the cable spool. 3. Cable Spool Assembly: A precision-machined cylindrical cable spool (approx. 40\text{ mm} diameter) mounted on a steel shaft supported by miniature ball bearings (SKF 6000 series). Features a dedicated circumferential groove (3\text{ mm} width) to wind and anchor the output Bowden cable leading to the throttle body. 4. Safety Override Mechanism (Slotted Slack-Link): Located on the input side (from the handlebar twist grip). Includes a sliding mechanical flat-bar link featuring a precision slot (approx. 15\text{ mm} length) to provide physical mechanical slack. A miniature override microswitch mounted adjacent to the sliding link to trigger a digital interrupt when pulled past the threshold. Assembly Constraints & Interfaces: Align the motor output through the electromagnetic clutch directly to the cable spool shaft. Route the input cable through the slotted slack-link mechanism to the spool, and route the output cable from the spool directly out the opposite end of the housing toward a Delphi throttle body cam interface.
