The second roller unit 45 includes a second shaft tube 450 inserted into the second shaft hole 432 of the second rocker arm 43 and protruded from one end of the second shaft tube 450 and clamped to the second a second flange 451 on the seat portion 433 and a second roller 452 pivotally mounted on the second shaft tube 450 and in rolling contact with the cam shaft 51. The first shaft tube 440 and the second shaft tube 450 are clamped to the first flange 442 and the second flange 451. The rocker arm 42 and the second rocker arm 43 do not need to be press-fitted, so it is not necessary to close one end of the first rocker arm 42 and the second rocker arm 43 away from each other.
該第二軸管450圍繞界定一對應該液壓槽441的接合槽453，該接合槽453是如圖5所示地具有一遠離該第二法蘭邊451的小孔徑端454、一相反於該小孔徑454端的大孔徑端455，及一形成於該小孔徑端454及大孔徑端455之間的頸部456。該大孔徑端455的孔徑大小與該液壓槽445之開放端447相同，並大於該小孔徑端454。該磁吸件46是設置於該液壓槽445的封閉端446，且呈圈環狀並圍繞出一與該液壓槽445相連通的孔隙461。 The second shaft tube 450 surrounds an engagement groove 453 defining a pair of hydraulic grooves 441. The engagement groove 453 has a small aperture end 454 away from the second flange edge 451 as shown in FIG. The large aperture end 455 of the small aperture 454 end and a neck 456 formed between the small aperture end 454 and the large aperture end 455. The large aperture end 455 has the same aperture size as the open end 447 of the hydraulic slot 445 and is larger than the small aperture end 454. The magnetic member 46 is disposed at the closed end 446 of the hydraulic groove 445 and has a ring shape and surrounds an aperture 461 communicating with the hydraulic groove 445.
該結合銷47可相對於該磁吸件46在一非結合位置及一結合位置間移動。在低轉速時，該結合銷47是被該磁吸件46吸附固定，而位於該非結合位置。此時，該第一搖臂42及該第二搖臂43並無連動，當該凸輪軸51之大凸塊512壓抵該第一滾輪443時，會使該第一搖臂42以該轉軸41為軸心作動旋轉，進而使該第一搖臂42之第一桿體部421壓縮該引擎裝置5之彈性件53，當該大凸塊512不壓抵該第一滾輪443時，該彈性件53之彈性偏移力使該第一搖臂42復位。當該凸輪軸51之小凸塊513壓抵該第二滾輪452時，會使該第二搖臂43以該轉軸為軸心作動旋轉，進而使該第二搖臂43之第二桿體部431壓抵該引擎裝置5之該等氣門閥52，使該等氣門閥52產生一較小的揚程，以減少進氣量。 The coupling pin 47 is movable relative to the magnetic member 46 between an unbonded position and a combined position. At a low rotational speed, the coupling pin 47 is adsorbed and fixed by the magnetic member 46 and is located at the unbonded position. At this time, the first rocker arm 42 and the second rocker arm 43 are not interlocked. When the large protrusion 512 of the camshaft 51 is pressed against the first roller 443, the first rocker arm 42 is caused by the rotating shaft. The first shaft portion 421 of the first rocker arm 42 compresses the elastic member 53 of the engine device 5, and the elastic member 53 is not pressed against the first roller 443. The resilient biasing force of member 53 resets the first rocker arm 42. When the small protrusion 513 of the cam shaft 51 is pressed against the second roller 452, the second rocker arm 43 is rotated about the rotation axis, and the second body portion of the second rocker arm 43 is further The valve valves 52, which are pressed against the engine unit 5, cause the valve valves 52 to generate a small lift to reduce the amount of intake air.
參閱圖4及圖6，在高轉速時，液壓油會由該第 一搖臂42的供油道423注入該環凹槽444內，並依序通過該第一滾輪單元44的注油孔441及該磁吸件46之孔隙461後流入該液壓槽445內，接著液壓油推動該結合銷47向該第二滾輪單元45的接合槽453凸入，使該結合銷47如圖6所示地部分伸置於該第二滾輪單元45的接合槽453內，並頂抵該接合槽453之頸部456而位於該結合位置。由於該環凹槽444是環繞開設，因此即使該第一滾輪單元44因故旋轉而使該注油孔441未對正該供油道423，液壓油也可順著該環凹槽444流入該注油孔441內。此時該第一搖臂42及該第二搖臂43是由該轉軸41及該結合銷47連接而形成一可連動之狀態。當該凸輪軸51之大凸塊512壓抵該第一滾輪443時，該第一搖臂42會連動該第二搖臂43旋轉，使該第二搖臂43以較大的旋轉幅度作動，進而驅動該等氣門閥52產生一較大的揚程，以增加進氣量。 Referring to Figures 4 and 6, at high speeds, hydraulic oil will be The oil supply passage 423 of the rocker arm 42 is injected into the ring groove 444, and sequentially passes through the oil injection hole 441 of the first roller unit 44 and the hole 461 of the magnetic member 46, and then flows into the hydraulic pressure groove 445, followed by hydraulic pressure. The oil pushes the engaging pin 47 into the engaging groove 453 of the second roller unit 45, so that the engaging pin 47 partially protrudes into the engaging groove 453 of the second roller unit 45 as shown in FIG. The neck 456 of the engagement groove 453 is located at the bonding position. Since the ring groove 444 is circumferentially opened, even if the first roller unit 44 rotates for the reason that the oil hole 441 is not aligned with the oil supply passage 423, the hydraulic oil can flow into the oil groove along the ring groove 444. Inside the hole 441. At this time, the first rocker arm 42 and the second rocker arm 43 are connected by the rotating shaft 41 and the coupling pin 47 to form a connectable state. When the large protrusion 512 of the camshaft 51 is pressed against the first roller 443, the first rocker arm 42 rotates the second rocker arm 43 to move the second rocker arm 43 with a large rotation amplitude. The valve valves 52 are then driven to generate a large head to increase the amount of intake air.
