請參閱第1圖，圖中揭示一花轂本體10、一棘輪筒20與一心軸30的組合。該心軸30穿過該花轂本體10及該棘輪筒20的軸向，如此該心軸30可以穿過安裝在該花轂本體10與該棘輪筒20內部的各構件。此外該心軸30用以安裝在一自行車的車架(未顯示)。 Referring to Figure 1, a hub body 10, a ratchet barrel 20 and a mandrel 30 are disclosed. The mandrel 30 passes through the hub body 10 and the axial direction of the ratchet barrel 20 such that the mandrel 30 can pass through various members mounted to the hub body 10 and the inside of the ratchet barrel 20. In addition, the mandrel 30 is for mounting on a bicycle frame (not shown).
請參閱第2圖，該花轂本體10的軸向為中空構造的一通道12。一傳動空間14形成在該通道12的一端。該棘輪筒20的一端具有一傳動塊22，且該傳動塊22用以穿入該傳動空間14。一花轂軸承40安裝在該花轂本體10的該通道12內。特別是，該花轂軸承40相鄰該傳動空間14。 Referring to FIG. 2, the hub body 10 has a channel 12 in a hollow configuration in the axial direction. A transmission space 14 is formed at one end of the passage 12. One end of the ratchet cylinder 20 has a transmission block 22, and the transmission block 22 is used to penetrate the transmission space 14. A hub bearing 40 is mounted within the passage 12 of the hub body 10. In particular, the hub bearing 40 is adjacent to the transmission space 14.
進一步，該傳動塊22的外表面具有複數棘輪塊用以嚙合該傳動空間14內壁面的棘齒部，使該棘輪筒20可以帶動該花轂本體10產生轉 動。另外也可以在該傳動空間14內安裝一個具有棘齒部的傳動環，再使該傳動塊22外表面的棘輪塊嚙合該傳動空環的該棘齒部，如此同樣可以達到該棘輪筒20帶動該花轂本體10產生轉動的效果。上述的該棘輪筒20與該花轂本體10的傳動機構為已知的結構形式。 Further, the outer surface of the transmission block 22 has a plurality of ratchet blocks for engaging the ratchet portions of the inner wall surface of the transmission space 14, so that the ratchet cylinder 20 can drive the hub body 10 to rotate. move. In addition, a transmission ring having a ratchet portion can be mounted in the transmission space 14, and the ratchet block on the outer surface of the transmission block 22 can be engaged with the ratchet portion of the transmission air ring, so that the ratchet cylinder 20 can also be driven. The hub body 10 produces a rotating effect. The above-described transmission mechanism of the ratchet cylinder 20 and the hub body 10 is of a known construction.
請參閱第2、3圖，一間隙50形成在該花轂軸承40與該傳動塊22的端面之間。 Referring to FIGS. 2 and 3, a gap 50 is formed between the hub bearing 40 and the end face of the transmission block 22.
該棘輪筒20與該花轂本體10為獨立構件，且該棘輪筒20既可以帶動該花轂本體10轉動，又可以相對該花轂本體10形成空轉，例如該棘輪筒20反向轉動時，花轂本體10不產生反向轉動；或自行車行進時，該棘輪筒20不轉動，該花轂本體10仍持續轉動；所以該棘輪筒20的該傳動塊22除了利用棘齒塊嚙合該花轂本體10的該棘齒部外，該花轂軸承40與該傳動塊22的端面之間的該間隙50可使該花轂本體10與該棘輪筒20能夠順利的產生相對轉動。 The ratchet cylinder 20 and the hub body 10 are separate members, and the ratchet cylinder 20 can drive the hub body 10 to rotate, and can form an idle motion relative to the hub body 10, for example, when the ratchet cylinder 20 rotates in the reverse direction. The hub body 10 does not produce reverse rotation; or the ratchet cylinder 20 does not rotate when the bicycle travels, the hub body 10 continues to rotate; therefore, the transmission block 22 of the ratchet cylinder 20 engages the hub with the use of a ratchet block Outside the ratchet portion of the body 10, the gap 50 between the hub bearing 40 and the end face of the drive block 22 allows the hub body 10 and the ratchet barrel 20 to smoothly rotate relative to each other.
然而，該花轂本體10與該棘輪筒20為獨立構件，且該棘輪筒20用以傳遞扭力及帶動該花轂本體10轉動，所以即便該花轂本體10可以搭配該花轂軸承40與該心軸30結合，該棘輪筒20可以配合適當的軸承與該心軸30結合，但該間隙50的存在仍會導致該棘輪筒20與該花轂本體10轉動時產生不穩定的狀態。 However, the hub body 10 and the ratchet cylinder 20 are separate members, and the ratchet cylinder 20 is configured to transmit torque and drive the hub body 10 to rotate, so that the hub body 10 can be matched with the hub bearing 40 and the The mandrel 30 is coupled, and the ratchet barrel 20 can be coupled to the mandrel 30 in conjunction with a suitable bearing, but the presence of the gap 50 can still result in an unstable state when the ratchet barrel 20 and the hub body 10 are rotated.
請參閱第2、3圖，為了解決前述的問題，本發明包含一間隙補償組件(a gap filling member)60。該間隙補償組件60配置在該花轂軸承40及該棘輪筒20的該傳動塊22之間。特別是，該間隙補償組件60的一端用以接觸該花轂軸承40，該間隙補償組件60的另一端通過該間隙50接觸該傳動 塊22。進一步，該間隙補償組件60的一端可以安裝在該傳動塊22內部，且該間隙補償組件60的另一端通過該間隙50靠抵該花轂軸承40的一端面。此外該心軸30也穿過該間隙補償組件60。 Referring to Figures 2 and 3, in order to solve the aforementioned problems, the present invention includes a gap filling member 60. The gap compensation assembly 60 is disposed between the hub bearing 40 and the transmission block 22 of the ratchet barrel 20. In particular, one end of the gap compensation assembly 60 is for contacting the hub bearing 40, and the other end of the gap compensation assembly 60 contacts the transmission through the gap 50. Block 22. Further, one end of the gap compensation component 60 can be mounted inside the transmission block 22, and the other end of the gap compensation component 60 abuts against an end surface of the hub bearing 40 through the gap 50. In addition, the mandrel 30 also passes through the gap compensation assembly 60.
由於該傳動塊22與該間隙補償組件60形成結合狀，該間隙補償組件60的一端通過該間隙50接觸(靠抵)該花轂軸承40的一端面，所以可以有效的降低該棘輪筒20與該花轂本體10轉動時產生相對歪斜的情形，以及有效降低該棘輪筒20與該花轂本體10產生相對轉動不穩定的情形。 Since the transmission block 22 is combined with the gap compensation component 60, one end of the gap compensation component 60 contacts (again) an end surface of the hub bearing 40 through the gap 50, so that the ratchet cylinder 20 can be effectively reduced. The hub body 10 is relatively skewed when rotated, and effectively reduces the relative rotational instability of the ratchet cylinder 20 and the hub body 10.
請再參閱第3圖，該間隙補償組件60包含一第一軸承62及一第二軸承64。該第一軸承62與該第二軸承64係採取並置的形式安裝在該傳動塊22內部。該第二軸承64的一部分更凸出該傳動塊22的端面且延伸通過該間隙50用以靠抵該花轂軸承40的端面。 Referring to FIG. 3 again, the gap compensation assembly 60 includes a first bearing 62 and a second bearing 64. The first bearing 62 and the second bearing 64 are mounted in a juxtaposed manner inside the transmission block 22. A portion of the second bearing 64 projects further from the end face of the transmission block 22 and extends through the gap 50 for abutting against the end face of the hub bearing 40.
請參閱第4圖，該間隙補償組件60為一單件雙並式軸承66。該單件雙併式軸承66具有二個滾珠部68。且二該滾珠部68皆位在該單件雙並式軸承66的軸向。該單件雙並式軸承66的一部分凸出該傳動塊22且延伸通過該間隙50靠抵該花轂軸承40的端面。 Referring to FIG. 4, the gap compensation assembly 60 is a one-piece, double-sided bearing 66. The one-piece double-sided bearing 66 has two ball portions 68. And the ball portion 68 is located in the axial direction of the single-piece double-sided bearing 66. A portion of the one-piece, double-sided bearing 66 projects out of the drive block 22 and extends through the gap 50 against the end face of the hub bearing 40.
請參閱第5、6圖，該間隙補償組件60為一第一軸套70及一第二軸套72的組合。其中該第一軸套70的軸向長度大於該第二軸套72的軸向長度，且該第一軸套70穿過該第二軸套72的軸向內部。該心軸30穿過該第一軸套70的軸向內部及該花轂軸承40的軸向內部。該第一軸套70的一端靠抵該花轂軸承40的一端面。又該第二軸套72為一種自潤乾式軸承。 Referring to FIGS. 5 and 6, the gap compensation assembly 60 is a combination of a first sleeve 70 and a second sleeve 72. The axial length of the first sleeve 70 is greater than the axial length of the second sleeve 72, and the first sleeve 70 passes through the axial inner portion of the second sleeve 72. The mandrel 30 passes through the axially inner portion of the first bushing 70 and the axially inner portion of the hub bearing 40. One end of the first sleeve 70 abuts against an end surface of the hub bearing 40. Further, the second sleeve 72 is a self-drying type bearing.
請參閱第7、8圖，該第一軸套70與該第二軸套72的組合安裝在該傳動塊22的內部。該第一軸套70的一部分凸出該傳動塊22且延伸通過 該間隙50靠抵該花轂軸承40的端面。 Referring to FIGS. 7 and 8, the combination of the first sleeve 70 and the second sleeve 72 is mounted inside the transmission block 22. A portion of the first sleeve 70 projects out of the transmission block 22 and extends through This gap 50 abuts against the end face of the hub bearing 40.
以上實施例所揭示的該間隙補償組件60藉其一端延伸通過傳動塊22與該花轂軸承40間的該間隙50，且使該間隙補償組件60的一端接觸靠抵該花轂軸承40，達到使該傳動塊22與該花轂軸承40形成連結用以配置該心軸30的軸向，進而使該棘輪筒20與該花轂本體10的轉動更為穩定。 The gap compensation assembly 60 disclosed in the above embodiment extends through the gap 50 between the transmission block 22 and the hub bearing 40 by one end thereof, and the one end of the gap compensation assembly 60 is brought into contact with the hub bearing 40 to reach The transmission block 22 is coupled to the hub bearing 40 for arranging the axial direction of the spindle 30, thereby further stabilizing the rotation of the ratchet barrel 20 and the hub body 10.
