The shock absorber 8 can be provided with a longer stroke, thereby further improving the shock absorption effect of the shock absorber 8. At the same time, the shock absorber 8 can be locked to the side frame 21 substantially parallel to the cylinder axis F, and the shock absorber 8 can be prevented from interfering with other components.
如圖三、五、六所示，當該機車1的後輪6欲作維修或更換時，只需先將該排氣裝置33、煞車組件9及土除10卸下，再卸除該後叉單元5第一後叉51的前第二後叉鎖付孔5111及後第二後叉鎖付孔5112，與該第二後叉52的前第一後叉鎖固孔525及後第一後叉鎖固孔526之鎖固元件S，來使該第一後叉51的上臂部511與該第二後叉52解除鎖固，同時卸除該第一後叉51的引擎本體鎖付孔5121之鎖固元件S，即可使該第一後叉51的下臂部512與該引擎本體31解除鎖固，藉此來使該後叉單元5的第一後叉51與該第二後叉52與該引擎本體31分離，再將該第一後叉51向下轉動一角度後，並將該後輪6朝該避震器8方向橫移，即可將第一後叉51連同後輪6一起卸下，來對該後輪6進行維修，因此可在無須卸下該避震器8的狀態下，即可對該後輪6進行維修動作，進而可便利該後輪6的維修性。 As shown in Figures 3, 5 and 6, when the rear wheel 6 of the locomotive 1 is to be repaired or replaced, the exhaust device 33, the brake assembly 9 and the soil removal 10 are first removed, and then removed. The front second rear fork locking hole 5111 and the rear second rear fork locking hole 5112 of the first rear fork 51 of the fork unit 5, and the front first rear fork locking hole 525 of the second rear fork 52 and the first The locking member S of the rear fork locking hole 526 is used to unlock the upper arm portion 511 of the first rear fork 51 and the second rear fork 52, and the engine body locking hole of the first rear fork 51 is removed. The locking member S of the 5121 can unlock the lower arm portion 512 of the first rear fork 51 and the engine body 31, thereby making the first rear fork 51 of the rear fork unit 5 and the second rear portion The fork 52 is separated from the engine body 31, and after the first rear fork 51 is rotated downward by an angle, and the rear wheel 6 is traversed toward the shock absorber 8, the first rear fork 51 can be combined with the rear fork 51. The wheel 6 is unloaded together to repair the rear wheel 6, so that the rear wheel 6 can be repaired without removing the shock absorber 8, and the rear wheel 6 can be easily repaired. Sex.
本發明之主要功效在於：藉由該避震器8的後端82鎖固用的該後叉單元5的避震器鎖付部522，係位於該後輪6的徑向範圍內，亦即由側視觀視，該避震器8的後端82係與該後輪6重疊，藉此可令該側車架21的連結部211與該後叉單元5的避震器鎖付部522之間可保持有較大的間距，進而可使該避震器8可具備有較長的行程，從而可提升該避震器8吸震效果，藉此來提升該機車的使用功效。 The main function of the present invention is that the shock absorber locking portion 522 of the rear fork unit 5 for locking by the rear end 82 of the shock absorber 8 is located in the radial range of the rear wheel 6, that is, The rear end 82 of the shock absorber 8 is overlapped with the rear wheel 6 by a side view, whereby the joint portion 211 of the side frame 21 and the shock absorber lock portion 522 of the rear fork unit 5 can be made. A large spacing can be maintained between the two, so that the shock absorber 8 can be provided with a long stroke, so that the shock absorbing effect of the shock absorber 8 can be improved, thereby improving the use efficiency of the locomotive.
本發明之機車後叉結構藉由上述之構造，確能達到訴求之目的，應已符合發明專利之新穎性、進步性及產業利用性之要件，爰依法提出發明專利之申請，祈請 貴審查委員之詳鑑，並賜核准發明專利之審定，至感德便。 The locomotive rear fork structure of the present invention can achieve the purpose of appeal by the above-mentioned structure, and should meet the requirements of the novelty, advancement and industrial utilization of the invention patent, and submit an application for the invention patent according to law, and pray for your review. The detailed examination of the members, and the approval of the approval of the invention patent, to the sense of virtue.
