变速器输出结构和内变速器

Abstract

本实用新型公开了一种变速器输出结构，并公开了具有变速器输出结构的内变速器，变速器输出结构包括多个棘爪槽、多个棘爪和多个弹性件，多个棘爪槽紧密环形分布于花鼓的内壁；多个棘爪环形分布于行星架的外侧；弹性件用于驱使棘爪卡在棘爪槽内，以使行星架能够单向驱动花鼓转动。在溜车状态下，棘爪可以滑过所有的棘爪槽，棘爪不会阻碍花鼓和车轮的转动，而在骑行者重新踩踏脚踏的时候，棘爪卡在棘爪槽内并通过棘爪槽驱动花鼓和车轮转动。由于花鼓的内径较换档杆的外径大得多，所以花鼓内壁上可设置的棘爪槽的数量较换档杆上的棘爪槽的数量大得多，使得花鼓上相邻两个棘爪槽所对应的圆心角较小，可以明显的减小踏空感，提高骑行体验。

Claims

1. A transmission output structure, characterized by, include: Multiple ratchet grooves (100) are closely arranged in a ring on the inner wall of the hub (10); Multiple pawls (200) are arranged in a ring on the outer side of the planet carrier (20); Multiple elastic elements (300) are provided to drive the pawl (200) to engage in the pawl groove (100) so that the planetary carrier (20) can drive the hub (10) to rotate in one direction.

2. The transmission output structure of claim 1, wherein, It also includes multiple adapter blocks (400), each of which is connected to the planetary carrier (20). Each adapter block (400) has an arc surface, and multiple storage slots (410) are provided on the arc surface. One end of the pawl (200) and the elastic element (300) are both located in the storage slot (410). The elastic element (300) drives the other end of the pawl (200) to extend outside the storage slot (410), so that the other end of the pawl (200) is locked on one side of the pawl groove (100).

3. The transmission output structure of claim 2, wherein, Limiting grooves (420) are provided on both sides of the storage groove (410). One end of the pawl (200) and one end of the elastic member (300) are respectively located in the two limiting grooves (420) to limit one end of the pawl (200) and one end of the elastic member (300).

4. The transmission output structure of claim 3, wherein, The inner walls of both limiting grooves (420) are arc surfaces. One end of the pawl (200) is rotatably disposed in one of the limiting grooves (420), and one end of the elastic member (300) is disposed in the other limiting groove (420). The other end of the elastic member (300) abuts against the side of the pawl (200) facing the adapter block (400).

5. The transmission output structure of claim 4, wherein, One end of the elastic element (300) is arc-shaped, and the other end of the elastic element (300) is plate-shaped.

6. The transmission output structure of claim 4, wherein, The receiving groove (410) and the limiting groove (420) both penetrate the side of the adapter block (400) so that the pawl (200) and the elastic member (300) can both enter the receiving groove (410) and the limiting groove (420) from the side of the adapter block (400).

7. The transmission output structure according to any one of claims 2 to 6, characterized in that, The adapter block (400) is provided with a connection hole (430).

8. The transmission output structure of claim 2, wherein, The number of the adapter blocks (400) is three, and the number of the storage slots (410) on each adapter block (400) is two.

9. The transmission output structure of claim 1, wherein, The number of ratchet grooves (100) is forty.

10. A powershift transmission characterized by Includes the transmission output structure and the internal transmission body according to any one of claims 1 to 9.
