Title:
平行二軸駆動装置
Document Type and Number:
Japanese Patent JP4669110
Kind Code:
B2
Abstract:
A drive arrangement clamps an output disc (90) such as a tire with two driving rollers (91, 92) so as to drive the output disc. The drive arrangement is compact, light-weight, low-noise and inexpensive, and can be used for a bicycle equipped with an electrical assist drive or various kinds of welfare-specific vehicles. The drive apparatus includes an input shaft (2) and two output shafts (3, 4) extending in a single plane in parallel to each other. The input shaft has an input roller (21), and each of the output shafts has an output roller (31, 41). A loading roller (51) is located between the input roller and one of the output rollers, and an axis of the loading roller is slightly spaced from the plane of the two output shafts. An outer peripheral surface of each roller is a substantially cylindrical rolling surface. The loading roller is preloaded by a preload spring (53) such that it squeezes between the input roller and one of the output rollers. A friction force generated on the rolling surface by a torque exerted on the input roller pushes in the loading roller between the rolling surfaces of the input roller and one of the output rollers so that a large normal force is produced between the rolling surfaces. A friction force at the rolling surface transmits the torque of the input shaft to the two output shafts.
