[0001] 相关申请的交叉引用 CROSS [0001] REFERENCE TO RELATED APPLICATIONS

[0002] 此申请基于2006年3月28日提交的2006-088977号日本专利申请和2006年3 月28日提交的2006-088978号日本专利申请,并要求其优先权,其全部内容通过引用被结合在本文中。 [0002] This application is based on Patent Application No. 2006-088978 Japanese Patent Application No. 2006-088977 Japan March 28, 2006 and filed on March 28, 2006 filed, and claims priority to, in its entirety by reference incorporated herein.

技术领域 FIELD

[0003] 本发明涉及用于内燃发动机的可调节阀门装置,其通过带有油控阀门的可调节阀门机构,所述可调节阀门装置可以在至少2种模式之间切换。 [0003] The present invention relates to an adjustable valve arrangement for an internal combustion engine, which can be adjusted by the oil control valve having a valve mechanism, the adjustable valve means can be switched between at least two modes.

背景技术 Background technique

[0004] 带有多个汽缸的安装在汽车上的往复式发动机(内燃发动机)的实例包括使用可调节阀门装置来切换到运行模式的发动机,在上述模式中,汽缸被部分地暂停,也就是,当发动机处于不需要大排放量的稳定运行状态时,用来平衡排放特性的改进和油料消耗的改进的汽缸暂停模式。 [0004] mounted with a plurality of cylinders in the example of a reciprocating engine (internal combustion engine) of the vehicle using the engine comprises an adjustable valve means to switch to the operating mode, when the mode, the cylinder is partially suspended, i.e. , when the engine is not required a large amount of a steady operating state emissions, fuel consumption and to improve the balance of improved emission characteristics of the cylinder of the pause mode. 例如,日本专利申请KOKAI公开号2005-90408披露了这类的发动机。 For example, Japanese Patent Application KOKAI Publication No. 2005-90408 discloses such an engine.

[0005] 通常,将液压型可调节阀门机构和用于汽缸暂停模式的油控阀门配备在汽缸盖内的结构被用于运行切换。 [0005] Generally, the hydraulic pressure type valve mechanism for an adjustable pause mode cylinder oil control valve provided in a cylinder head structure is used for the switching operation. 在该结构中,液压可调节阀门机构可以切换到使汽缸部分地暂停的汽缸暂停模式,并且用于汽缸暂停模式的油控阀门将可调节阀门机构切换到汽缸暂停模式。 In this configuration, the adjustable hydraulic valve mechanism can be switched to the cylinder partially suspended cylinder pause mode and pause mode for the cylinder oil control valve to the adjustable valve mechanism is switched to the pause mode of the cylinder.

[0006] 当发动机进入预定的汽缸暂停运行范围时,用于汽缸暂停模式的油控阀门在结构中被操作。 [0006] When the engine enters a predetermined range pauses cylinder, the cylinder for oil control valve is operated in the pause mode configuration. 发动机油从安装在发动机机身上的润滑油泵经过控制阀门被提供到可调节阀门机构。 Engine oil from the lubricating oil pump is installed in an engine body through a control valve is provided to an adjustable valve mechanism. 然后,可调节阀门机构被发动机油的油压驱动,进气阀门的升高(打开和闭合)和汽缸的排气阀门被暂停(汽缸暂停模式)。 Then, the adjustable valve means is a hydraulic motor driven oil, increased intake valve (opening and closing) of the cylinder and the exhaust valve is suspended (cylinder pause mode).

[0007] 因为安装在发动机机身上的润滑油泵通常由曲轴驱动,从润滑油泵放出的发动机油的油压取决于发动机的转速。 [0007] Since the lubricating oil pump is mounted in the engine body is usually driven by the crankshaft, lubricating oil discharged from the oil pump of the engine depends on engine speed. 当发动机转速下降,润滑油泵产生的油压就低,当发动机转速上升,油压就高。 When the engine speed drops, the oil pressure generated by the lubricating oil pump is low, when the engine speed increases, the oil pressure is high.

[0008] 当发动机切换到汽缸暂停模式,可调节阀门机构的零件要承受从外部施加的力, 所以,必须要有用于驱动的油压。 [0008] cylinders when the engine is switched to the pause mode, the adjustable part of the valve mechanism to bear the force applied from the outside, so there must be a hydraulic driving.

[0009] 因此,在润滑油泵中,用于切换可调节阀门机构所必须的油压在低发动机转速范围内不能被充分地保证。 [0009] Thus, the lubricating oil pump, the adjustable valve mechanism for switching the necessary hydraulic pressure can not be sufficiently guaranteed in the low engine speed range. 由于这个原因,在低发动机转速范围内汽缸暂停模式下的运行很难进行,因此,在汽缸暂停模式下进行运行的汽缸暂停运行范围被很大地限制。 For this reason, running in a low engine speed range within a cylinder pause mode difficult, therefore, for a cylinder running in a cylinder pause mode pauses range is greatly limited.

[0010] 有些发动机包括汽缸盖,可调节阀门机构,用于汽缸暂停模式的油控阀门和用于独立于润滑油泵地切换到汽缸暂停模式的凸轮轴驱动的油泵。 [0010] Some engine comprising a cylinder head, an adjustable valve means, the cylinder for oil control valve pause mode for a camshaft driving an oil pump independent handover to a cylinder pause mode in the lubricant pump. 结果,即使在低发动机转速范围内也可以保证切换可调节阀门机构所必须的油压。 As a result, even in a low engine speed range can be adjusted to ensure the switching valve mechanism necessary hydraulic pressure.

[0011] 在带有用于切换到汽缸暂停模式的油泵的可调节阀门装置中,切换到汽缸暂停模式的频率比使用已经安装在发动机内的润滑油泵有所增加。 Lubricant pump [0011] In an oil pump with an adjustable valve means for switching to the pause mode of the cylinder, the cylinder is switched to the pause mode frequencies than has been installed in the engine has increased. 特别是,当使用专门的油泵,在汽缸暂停模式下进行运行的机会增加了,因为在低发动机转速范围内运行的汽缸暂停模式可以连同在汽缸暂停模式下空转被进行。 In particular, when using a special oil pump, the opportunity to run in the cylinder suspended mode increases, since running in the low speed range of the engine cylinder pause mode may be performed in conjunction with the idle cylinder pause mode.

[0012] 因此,当用于汽缸暂停模式的油控阀门传统地具有低维护频率时,用于汽缸暂停模式的油泵的使用增加了进行对带有用于汽缸暂停模式的油泵的用于汽缸暂停模式的油控阀门的维护的机会。 [0012] Thus, when the oil control valve for cylinders pause mode conventionally having a low frequency of maintenance, an oil pump for cylinder pause mode to be increased with a pump for cylinder pause mode for a cylinder pause mode maintenance chance of oil control valve. 因此,用于汽缸暂停模式的油控阀门的维护的重要性增加了。 Therefore, the importance of oil control valve cylinder pause mode for maintenance increases.

[0013] 然而,在用于汽缸暂停模式的油控阀门和用于汽缸暂停模式的油泵被容纳在汽缸盖中的结构中,用于汽缸暂停模式的油控阀门不能被进行维护,除非阻挡住汽缸盖上部的摇杆罩被拆卸掉。 [0013] However, in the oil control valve for an oil pump and a cylinder suspended mode, a pause mode for a cylinder accommodated in the cylinder head structure in the oil control valve for cylinders pause mode can not be maintained unless stop the rocker cover portion is split cylinder head removed. 这导致用于汽缸暂停的油控阀门的维护工作产生麻烦,其中增加了维护频率。 This results in a maintenance cylinder suspended oil control valve produces trouble, which increases the maintenance frequency.

[0062] 在轮毂36的外圆周表面上,制轮器41从轮毂36面向未升高凸轮31的区域向未升高凸轮31的外圆周表面突出,如图14到16所示。 The [0062] hub in the outer circumferential surface 36, 41 is made from a hub wheel 36 for the cam 31 is not elevated to the region of the outer circumferential surface of the projecting cam 31 is not raised, as shown in FIG. 14-16.

[0063] 制轮器41的突出长度被设定为这样的尺寸,当进气阀门13a和13b关闭时,允许制轮器41的前端部紧靠未升高凸轮31的外圆周表面。 Protruding length [0063] Wheel 41 is set to such a size, when the intake valves 13a and 13b are closed, the distal end portion 41 allows the wheel braking against an outer circumferential surface of the cam 31 does not rise. 当进气阀门13a和13b被关闭,通过进气阀门13a和13b的阀门弹簧的反应力令制轮器41紧靠未升高凸轮31,防止整个阀门驱动摇杆35的意外动作。 When the intake valves 13a and 13b are closed, the inlet valve by the reaction force of the valve springs 13a and 13b so that the wheel 41 is made against the cam 31 does not rise, the entire valve to prevent accidental operation of the drive rocker 35.

[0064] 活塞型的一个被采用作为被排布在轮毂36的两端的切换操作部件40a和40b。 [0064] a piston-type is adopted as the ends are arranged in the hub 36 of the switching operation member 40a and 40b. 排布在进气凸轮33 (用于低速)的侧的切换操作部件40a将在下面被说明。 Arranged in the intake side cam 33 of the switching operation member (for low speed) of 40a will be explained below. 在图11、15和16 中,参考标号43是汽缸,它形成在摇杆臂37的基础部件进气凸轮33的一侧,将作为例子。 In FIGS. 11, 15 and 16, reference numeral 43 is a cylinder, which is formed in the side of the base member 37 of the rocker arm of the intake cam 33, as an example. 汽缸43是纵向的一个,沿摇杆轴26的径向延伸。 43 is a vertical cylinder, a rocker shaft 26 extending in radial direction. 窗口44形成在汽缸43的较低部的前表面上(凸轮轴25的侧的表面)。 Window 44 is formed on the front surface of the lower portion of the cylinder 43 (the side surface of the camshaft 25).

[0065] 从汽缸43的底面到位于汽缸43直接下方的轮毂36的内表面36a (轴承面)形成具有比汽缸43小的直径的通孔45(只显示在图11中)。 [0065] 36a (bearing surface) formed in the through hole 45 has a smaller diameter than the cylinder 43 of the cylinder 43 from the bottom surface to the inner surface 36 of the hub 43 is located directly below the cylinder (only shown in FIG. 11). 活塞46作为承受部件与使活塞46偏离汽缸43的底部的压缩弹簧47(只显示在图11中)一起位于汽缸43中。 As the piston 46 and the piston receiving member 46 offset from the bottom of the cylinder 43 the compression spring 47 (only shown in FIG. 11) located in the cylinder 43 together.

[0066] 以此结构,通常汽缸43的窗口44被活塞46的较低外圆周表面关闭。 [0066] In this structure, the window 43 of the cylinder 44 is usually closed by the lower outer circumferential surface of the piston 46. 当活塞46 升高,活塞46从窗口44被缩回以打开窗口44。 When the rise of the piston 46, the piston 46 is retracted from the window 44 to open the window 44. 如图11所示,销子48可滑动地容纳于通孔45中。 Illustrated, pin 48 slidably received in the through hole 45 in FIG. 11. 位于通孔45下端的开口与从油路26a分出的支路通路49相连通。 Located at the lower end of the through hole 45 from the oil passage 26a and opening the bypass channel 49 separated communicated. 结果,当通过油路26a对销子48施加油压,堵住窗口44的活塞46通过销子48的升高运动被驱动向活塞46从窗口44缩回的方向,如图11中的1长2短虚线所示。 As a result, hydraulic pressure is applied to the pin when the piston 48 through the oil passage 26a, the window 44 of the block 46 is driven by the rising motion of the pin 48 in the direction of the piston 44 is retracted from the window 46, as shown by a long 11 two short dashed line in FIG. 也就是,窗口44被打开。 That is, the window 44 is opened.

[0067] 和切换操作部件40a —起,汽缸51形成在摇杆臂37基础部件中这样的结构被使用在位于进气凸轮30 (用于高速)一侧的切换操作部件40b中,如图12、15和16所示。 [0067] and the switch operation member 40a - from, the cylinder 51 is formed in such a configuration the base part of the rocker arm 37 are located in the intake cam 30 (for high speed) side of the switch operation member 40b in FIG. 12 15 and 16. 汽缸51延伸向轮毂36的内表面36a从而获得冲量。 A hub cylinder 51 extending to the inner surface 36 of the wheel 36a to thereby obtain impulse.

[0068] 因此,与汽缸51连续地连通的通孔52被制造在位于汽缸51紧接下方的摇杆轴26 中。 [0068] Thus, the through-hole 52 communicating with the cylinder 51 are continuously manufactured in the rocker shaft 26 immediately below the cylinder 51 is located. 通孔52的直径小于汽缸51的直径。 Diameter of the through hole 52 is smaller than the diameter of the cylinder (51). 不同于切换操作部件40a,如图12所示,窗口50 形成在汽缸51的上前表面上,并且活塞53与使活塞53偏离汽缸51底部的压缩弹簧54 — 起被容纳于汽缸51中。 Unlike switching operation member 40a, as shown in FIG 12 windows 50 are formed on the front surface of the cylinder 51 and the piston 53 and the bottom portion 53 of the piston cylinder (51) departing from the compression spring 54 - from the cylinder 51 is housed.

[0069] 低轮廓活塞被用作活塞53以使得活塞53能够被容置在汽缸部中,在从窗口50的下侧。 [0069] is used as the low profile of the piston 53 to the piston such that the piston 53 can be accommodated in the cylinder portion, the window 50 from the side. 与切换操作部件40a相反,通常汽缸51的窗口50的开口是打开的,并且当活塞53 升高,开口被活塞53的外圆周表面关闭。 Instead the switching operation member 40a, the cylinder 51 is usually open window 50 is open, and when the piston 53 rises, the opening is closed outer circumferential surface of the piston 53.

[0070] 如图12所示,销子55可滑动地容置于通孔52中,通孔52的低端部与油路26b的一部分相连通而与油路26b相交叉。 [0070] As shown, a pin 55 slidably received 12 disposed through hole 52, a portion of the lower end portion of the through hole 52 and the oil passage 26b is connected with the oil passage 26b through crossing. 当通过油路26b向销子55施加油压,从而,活塞53通过销子55的升高运动被驱动向活塞53阻断窗口50的方向,如图12中1长2短虚线所示。 When the hydraulic pressure is applied to the pin 55 through the oil passage 26b, so that the piston 53 is driven by the rising motion of the pin 55 in the direction of the window 50 to block the piston 53, 12 in a length of 2 short dash line shown in FIG. 也就是,窗口50被关闭。 That is, the window 50 is closed.

[0071] 如图16所示,凹口57形成在轮毂36的两端部的开口边缘上。 [0071] As shown in FIG. 16, the notches 57 are formed on both end portions of the opening edge 36 of the hub. 凹口57是以这样的方式形成的,在形成轮毂端的圆周壁上,排列在从汽缸43和51的直接下方的部件到穿过轮毂前部的摇杆臂37的基础部件(在与摇杆臂37相反的侧)的圆周部件被连续切掉。 Recess 57 is formed in such a manner, the peripheral wall of the hub wheel side is formed, arranged in the base member directly below the cylinder member 43 and through the rocker arm 51 to the front portion of the hub 37 (the rocker opposite side arms 37) a continuous circumferential member is cut away.

[0072] 如图4到6、12、15和16所示,高速侧凸轮跟随摇杆70被排布靠近轮毂36 (阀门驱动摇杆)的进气凸轮30 (用于高速)的侧的端部。 [0072] FIGS. 4 to 6,12,15 and 16, the high-speed rocker cam followers 70 are arranged close to the hub 36 (the valve drive rocker) of the intake cam 30 (for high speed) side of the end unit. 凸轮跟随摇杆70包括圆柱摇杆轴支撑轮毂71,一对滚筒支撑片(滚筒套)72,滚筒(转动接触)73,和结合器79。 The cam follower rocker rocker shaft support 70 includes a cylindrical hub 71, a pair of roller support plate (roller cover) 72, the drum (rotational contact) 73, and a combiner 79. 定位在靠近轮毂36端的摇杆轴26可转动地安装于轮毂71。 The hub 36 is positioned close to the end of the rocker shaft 26 is rotatably mounted to the hub 71. 滚筒支撑片72直线地从轮毂71的两端部向进气凸轮30 (用于高速)的上方突出。 Cylinder support plate 72 projecting upward linearly from both ends of the hub 71 to the intake cam 30 (for high speed) is. 滚筒73被可转动地支撑在滚筒支撑片72的前端部之间。 Roller 73 is rotatably supported between the front end portion of the cylinder support plate 72. 结合器79形成在轮毂71的圆周壁中。 79 in conjunction with the hub 71 is formed in the circumferential wall.

[0073] 因此,凸轮跟随摇杆70有这样的构成,滚筒73位于凸轮跟随摇杆70的一端,结合器位于凸轮跟随摇杆70的另一端。 [0073] Thus, the cam follower rocker 70 has such a configuration, the roller 73 of the cam follower rocker end, in conjunction with the cam follower 70 and the other end 70 of the rocker. 当接触进气凸轮30的凸轮表面,滚筒73被转动。 When the cam surface in contact with the air intake cam 30, the drum 73 is rotated. 当凸轮轴25被转动,凸轮跟随摇杆70关于轮毂71转动,也就是,凸轮跟随摇杆70跟随进气凸轮30的位移而摇摆。 When the camshaft 25 is rotated, the cam follower 70 on the rocker wheel 71 rotates, i.e., the rocker cam follower 70 follows the displacement of the air intake cam 30 and swing.

[0074] 如图16所示,凹口76形成在靠近轮毂36 (阀门驱动摇杆)的轮毂71的端部上。 As shown in [0074] 16, a notch 76 is formed on the end portion 36 near the hub (the valve drive rocker) 71 of the hub. 凹口76是通过切掉与轮毂36(阀门驱动摇杆)相反的侧的圆周壁部件来形成的。 Notch 76 is cut through the hub 36 (the valve drive rocker) opposite to the side of the circumferential wall member to form.

[0075] 例如,从轮毂71的上侧到轮毂71的前方(与滚筒73相反一侧)的圆周部件被连续切掉。 Forward [0075] For example, the hub 71 from the upper side to the wheel hub 71 (opposite to the drum 73) a continuous circumferential member is cut away. 在轮毂71端的凹口76和在轮毂36端的凹口57以补充的方式分别被装配至遗留在轮毂36的开口端的边缘部件36b和遗留在轮毂71的开口端的边缘部件71b。 In the hub 71 end of the recess 76 and the hub 36 end of the recess 57 in a complementary manner are fitted to the open end is left in the hub 36 of the edge member 36b and the edge member open end of the left hub 71 71b.

[0076] 上述部件的装配允许所要求的凸轮跟随摇杆70的运动。 Assembly [0076] The cam member is allowed to follow the movement required of the rocker 70. 通过装配,在轮毂36端的边缘部件36b和在轮毂71端的边缘部件71b在摇杆轴26的外圆周表面中围绕摇杆轴26 的轴线方向重叠。 By fitting, the end edges 36 of the hub member 36b and the end edge 71 of the hub member 71b overlaps the axial direction of the rocker shaft 26 about the outer circumferential surface of the rocker shaft 26. 结合器79被排布在边缘部件71b中,并且窗口50、汽缸51、活塞53和压缩弹簧54被排布在边缘部件36b中。 Combiner 79 is arranged in the edge member 71b, and the window 50, the cylinder 51, the piston 53 and the compression spring 54 is arranged in the edge of the member 36b.

[0077] 结合器79和活塞53被定位以当边缘部件36b和边缘部件71b重叠时互相面对。 [0077] The coupler 79 and the piston 53 is positioned when the member 36b and the edge 71b overlaps edge member face each other. 因此,如图15和16所示,轮毂71的结合器79和位于轮毂36中的窗口50通过利用边缘部件71b和36b的摇杆轴26在圆周方向上的并排排列而互相面对。 Therefore, as shown in FIG. 15 and 16, in conjunction with the hub 71 of the hub 79 and 36 by using window 50 arranged side by side edge 71b and the rocker member 26 of the shaft 36b in the circumferential direction, and face each other.

[0078] 靠近轮毂36 (内侧)排列的滚筒支撑片72的支撑片被排列成在结合器79前方完全笔直。 [0078] near the hub cylinder support plate 36 (inner side) arranged in the support plate 72 is aligned perfectly straight in front of the combiner 79. 另一侧的滚筒支撑片72和结合器79被排列成相对窗口50成一直线。 The other side of the cylinder support plate 72 and the combiner 50 in line 79 is arranged opposite the window.

[0079] 如图15和16所示,轮毂71的外圆周表面有配备于从结合器79到内侧滚筒支撑片72 (靠近轮毂36)的范围内的翼部件74。 As shown in [0079] 15 and 16, an outer circumferential surface of the hub 71 it is provided to the combiner 79 from the inside of the drum to the support plate 72 within the flap member (36 near the hub) 74 range. 翼部件74由连续并直线连接结合器79的肋78和滚筒支撑片72形成。 And the wing member 74 by a continuous line connecting the coupling rib 79 support sheet 78 and the drum 72 is formed.

[0080] 结合器79被形成为这样的形状,其允许肋78的前端部的水平壁进入和离开窗口50。 [0080] The combiner 79 is formed into a shape, which allows the distal portion 78 of the horizontal wall rib entering and exiting the window 50. 以这个形状,通常,结合器79通过窗口50进入和离开汽缸51。 In this form, usually, 79 through the window into the combiner 50 and out of the cylinder 51. 当窗口50被活塞53阻塞,结合器79紧贴在从窗口50暴露的活塞53上。 79 when the window 50 is exposed from the close contact with the window 50 of the piston 53 of the piston 53 blocked combiner.

[0081] 也就是,高速进气凸轮30从凸轮跟随摇杆70起的位移是否被传递到阀门驱动摇杆35的切换到是基于结合器79是冲击空气还是抵靠在活塞53上而被进行的。 [0081] That is, the high-speed intake cam 30 drives the cam follower 70 from the displacement is transmitted to the rocker whether the valve from the rocker switch 35 to 79 is based on a combination of air or the impact against the piston 53 and is subjected to of. 结合器79 和活塞53构成切换机构79a。 Combiner 79 and the piston 53 constitute the switching mechanism 79a.

[0082] 支座75形成在外侧滚筒支撑片72的前端侧上以接受来自被装配到摇杆轴盖130 中的推动器70a的偏离力(使滚筒73挤压进气凸轮30的力)。 [0082] The seat 75 is formed on the front end side of the outer cylinder support plate 72 is fitted to receive from the inflection force (force of the drum 73 pressed into the intake cam 30) of the rocker shaft cover 130 of the pusher 70a.

[0083] 如图4到6、11、15和16所示,低速侧凸轮跟随摇杆60被排布成靠近轮毂36的进气凸轮33 (用于高速)的侧的端部。 [0083] FIGS. 4 to 6,11,15 and 16, the low-speed cam follower rocker 60 is arranged close to the inlet end of the hub 36 of the cam 33 side (for high speed) is. 凸轮跟随摇杆60具有和高速侧凸轮跟随摇杆70对称的结构。 The cam follower and a rocker 60 having a high-speed cam follower rocker 70 symmetrical structure. 因为凸轮跟随摇杆60具有和凸轮跟随摇杆70相同的结构,用标号61到69代替表示凸轮跟随摇杆70的部件的标号71到79表示凸轮跟随摇杆60的相同部件,并且说明 Since the cam follower and a cam follower rocker 60 having the same structure as the rocker 70, indicated by reference numerals 61 to 69 instead of the cam follower member 70 of the rocker reference numerals 71 to 79 represent the same cam follower rocker member 60, and the description

被省略。 It is omitted.

[0084] 显然,结合器69被形成这样的形状,允许结合器69进入和离开窗口44。 [0084] Obviously, the combiner 69 is formed in such a shape that allows the coupler 69 to enter and leave the window 44. 同样地对于凸轮跟随摇杆60,通常,结合器69紧贴在活塞46上,阻塞窗口44,如图11所示。 Similarly to the cam follower rocker 60, Typically, combiner 69 close contact with the piston 46, blocking the window 44, as shown in FIG. 当窗口44被活塞46打开,结合器69通过窗口44进入和离开汽缸43。 When the window 46 is opened by the piston 44, combiner 69 through the window 44 into and out of the cylinder 43. 也就是,低速进气凸轮33 从凸轮跟随摇杆60起的位移是否被输入到阀门驱动摇杆35的切换是基于结合器69冲击空气还是抵靠在活塞46上而被进行的。 That is, the low-speed intake cam 33 from the cam followers 60 from the displacement of the joystick is inputted to whether the switching valve drive rocker 35 is based on the combiner 69 or the impingement air against the piston 46 to be carried out. 结合器69和活塞46构成切换机构69a。 Combiner 69 and piston 46 constitute the switching mechanism 69a.

[0085] 如图4到6、13、17和18所示,具有跟随排气凸轮32的凸轮跟随摇杆80和驱动排气阀门15a和15b的阀门驱动摇杆90的液压摇杆臂被用于排气摇杆臂模块19。 [0085] FIGS. 4 to 6,13,17 and 18, an exhaust cam follower having a cam follower 32 and rocker 80 driving the exhaust valves 15a and 15b of the valve driving rocker arm 90 is a hydraulic rocker with an exhaust rocker arm module 19.

[0087] 当与排气凸轮32的凸轮表面相接触时,滚筒83被转动。 [0087] When in contact with the cam surface of the exhaust cam 32, the drum 83 is rotated. 当凸轮轴25被转动,凸轮跟随摇杆80被关于轮毂81转动,也就是,凸轮跟随摇杆80当跟随排气凸轮32的位移时被摇摆。 When the camshaft 25 is rotated, the cam follower rocker 80 is rotated about the hub 81, i.e., when the cam follower 80 follows the displacement of the exhaust rocker cam 32 when the swing. 支座85形成在凸轮跟随摇杆80的前端部上从而接受来自装配在摇杆轴盖130内的推动器80a的偏离力(使滚筒83挤压排气凸轮32的力)。 Seat 85 is formed in the front end portion of the rocker cam follower 80 to thereby departing from receiving a force from the rocker shaft mounted in the pusher head 130 80a (the pressing force of the drum 83 of the exhaust cam 32).

[0088] 翼部件84是通过肋86沿轮毂81的外表面的宽度方向向中心突出形成的。 [0088] The wing member 84 is formed projecting toward the center of the outer surface of the hub 81 in the width direction by the ribs 86 along the wheel. 肋86 沿轮毂81的圆周方向从滚轮支撑件82的后端部向轮毂81的上部延伸。 Ribs 86 along the circumferential direction of the wheel hub 81 from the rear end portion of the roller support member 82 to the upper portion of the wheel 81 extends. 向前突出而形成的结合器89位于肋86的前端部。 Projecting forwardly is formed in conjunction with the ribs 89 of the distal portion 86.

[0089] 如图4到6、13、17和18所示,阀门驱动摇杆90包括排列在轮毂81 (凸轮跟随摇杆80)两侧的摇杆臂91和模式切换操作部件98。 [0089] FIGS. 4 to 6,13,17 and 18, the valve 90 comprises a rocker arranged in the drive hub 81 (the cam follower rocker 80) on both sides of the rocker arm 91 and the mode switching operation member 98.

[0090] 一对圆柱摇杆轴支撑轮毂92被配备于摇杆臂91的一个端部件中。 [0090] The rocker shaft supporting a pair of cylindrical hub 92 is provided at one end of the rocker arm member 91. 摇杆轴27被可转动地装配在轮毂92两侧,轮毂81 (凸轮跟随摇杆80)被定位于轮毂92之间。 The rocker shaft 27 is rotatably fitted on both sides of the wheel hub 92, the hub 81 (the cam follower rocker 80) is positioned between the hub 92. 臂93被配备于摇杆臂91的另一端部件中,臂93被直线地从轮毂92分别向排气阀门15a和15b延伸。 Arm 93 is provided at the other end of the rocker arm member 91, the arm 93 is linearly extended from the hub 92 toward the exhaust valves 15a and 15b, respectively.

[0091] 调节螺丝94被配备于臂93的前端部件中。 [0091] The adjustment screw 94 is provided at a front end 93 of the arm member. 调节螺丝94被分别排列在排气阀门15a和15b的上端(阀杆端)。 Adjusting screw 94 are respectively arranged in the exhaust valve 15a and the upper end (stem side) of 15b.

[0092] 臂93和93的前端部件通过,例如,盘形连接臂95被连接。 [0092] The arm 93 and the distal end member 93 by, for example, a disc-shaped connecting arm 95 is connected. 因此,阀门驱动摇杆90 具有门形。 Thus, the valve drive rocker 90 has a gate shape. 当阀门驱动摇杆90被关于摇杆轴27摇摆,多个排气阀门15a和15b被驱动。 When the valve drive rocker 90 swinging on the rocker shaft 27, a plurality of exhaust valves 15a and 15b are driven.

[0093] 如图14、17和18所示,制轮器96被配备以从排列在未升高凸轮31上方的轮毂92 的外圆周表面向未升高凸轮31的外圆周表面突出。 [0093] and shown in FIG. 14, 17, 18 Wheel 96 is provided with an outer circumferential surface of the cam arrangement 31 is not raised above the hub 92 protrudes toward the outer circumferential surface of the cam 31 is not increased.

[0094] 制轮器96的突出长度被设定了这样的尺寸,当排气阀门15a和15b被关闭,允许制轮器96的前端部件靠近未升高凸轮31的外圆周表面。 Protruding length [0094] Wheel 96 is set to such a size, when the exhaust valves 15a and 15b are closed, allowing the wheel braking member 96 adjacent the front end of the outer circumferential surface of the cam 31 does not rise. 当排气阀门15a和15b被关闭, 制轮器96通过排气阀门15a和15b的阀门弹簧的反应力紧贴在未升高凸轮31上,防止整个摇杆臂91的意外动作。 When the exhaust valves 15a and 15b are closed, the wheel 96 is made by the reaction force of the valve spring and the exhaust valve 15a and 15b is not raised against the cam 31, the rocker arm 91 to prevent accidental entire operation.

[0095] 如图13、17和18所示,切换操作部件98被设置在连接臂95上。 [0095] As shown in FIG. 13, 17 and 18, a switching operation member 98 is disposed on the connecting arm 95. 活塞类型1被用作切换操作部件98,如图13所示。 1 is used as a piston type switching member 98, as shown in Fig.

[0096] 下面说明切换操作部件98。 [0096] Next, a switching operation member 98. 在图13中,参考标号99是垂直汽缸。 In Figure 13, reference numeral 99 is a vertical cylinder. 汽缸99被形成为从连接臂95中心向上突出。 Cylinder 99 is formed to protrude upwardly from the central arm 95 is connected. 汽缸99向汽缸99从摇杆轴27分离的方向倾斜。 Cylinder 99 99 inclined in the direction of the rocker shaft 27 to separate the cylinder. 窗口100 形成在汽缸99的低部件的前表面(凸轮轴25的侧上的表面)。 Window 100 is formed in the front lower surface of the cylinder member 99 (the surface on the side of the camshaft 25). 具有比汽缸99小的直径的通孔101被制造在从汽缸99的底到位于汽缸99直接下方的臂的内侧。 It is made having a cylinder 99 than the through-hole of a small diameter cylinder 101 in the inner side from the bottom 99 of the arm 99 directly to the bottom of the cylinder.

[0097] 作为承受部件的活塞102与使活塞102偏离汽缸底的压缩弹簧103 —起容纳于汽缸99中。 [0097] As the piston receiving member and the compression spring 102 the piston 102 is offset from the cylinder bottom 103-- from 99 housed in the cylinder. 也就是,通常,汽缸99的窗口100被活塞102的外圆周表面关闭,当活塞102升高,活塞102从窗口100被抽回以打开窗口100。 That is, generally, the cylinder 99 is an outer circumferential surface of the window 100 of the piston 102 is closed, when the rise of the piston 102, the piston 102 is withdrawn from the window 100 to open the window 100.

[0098] 销子104被可滑动地容纳于通孔101中。 [0098] pin 104 is slidably received in the through hole 101. 如图6和13所示,位于通孔101低端的开口与形成在连接臂95中的延迟通路105相连通。 6 and, connected at the lower end of an opening 95 formed in the connecting arm 101 of the through hole 13 through the delay path 105 shown in FIG. 延迟通路105通过形成在臂93中的延迟通路106向轮毂92的内表面打开。 Delay passage 105 formed on the arm 93 delay passage of the hub 106 is open to the inner surface 92 of the wheel.

[0099] 延迟通路106与从油路27a分支出的支路通路107 (只显示在图13中)相连通。 [0099] Delay path 106 and the oil passage 27a branching from the bypass passage 107 (only shown in FIG. 13) in communication. 当油压通过油路27a施加到销子104上,阻塞窗口100的活塞102被朝活塞102通过销子104的升高运动与窗口100相分离的方向驱动,如图13中的1长2短虚线所示。 When the hydraulic pressure is applied to the pin 27a through the oil passage 104, piston 102 blocking window 104 is increased by movement of the drive pin 100 in a direction toward the piston 102 separate window 100, as shown in the short length 131 shown in phantom. 也就是,窗口100被打开。 That is, the window 100 is opened.

[0100] 凸轮跟随摇杆80的结合器89位于窗口100前方。 [0100] The cam follower 80 of the rocker 89 in conjunction with the front window 100 is located. 如图17和18所示,结合器89 被形成为这样的形状,允许结合器89进入和离开窗口100。 17 and FIG, 18, 89 is formed in conjunction with such a shape as to allow coupler 89 to enter and leave the window 100. 以此结构,通常,结合器89紧贴在阻塞窗口100的活塞102上。 In this structure, generally, in the combiner 89 against a congestion window 100 of the piston 102. 当窗口100被打开,结合器89通过窗口100进入和离开汽缸99。 When the window 100 is opened, the combiner 100 through the window 89 into and out of the cylinder 99. 换句话说,排气凸轮32从凸轮跟随摇杆80起的位移是否被传递到阀门驱动摇杆90的切换是基于结合器89冲击空气还是抵靠在活塞102上而被进行的。 In other words, the exhaust cam follower 32 is displaced from the rocker cam 80 from whether the handover is transmitted to the valve drive rocker 90 is based on the combiner 89 or the air impact against the piston 102 is performed. 结合器89和活塞102构成切换机构97。 Combiner 102 and the piston 89 constitute the switching mechanism 97. 此结构也在左组7a的每个汽缸3中被采用。 This structure is also left for each cylinder group 3, 7a are employed.

[0101] 右组7b中的可调节阀门系统17b的每个摇杆臂模块20有这样的结构,其中不驱动阀门的机构和部分被从左组7a中的进气摇杆臂模块18上移除。 [0101] 7b, right panel adjustable valve system 17b of each rocker arm module 20 has a structure in which the shift mechanism is not driven and the valve portion 7a in the left group intake rocker arm module 18 except. 虽然没有显示细节,在所述结构中,低速侧切换结构(主要是切换操作部件40a和凸轮跟随摇杆60)被省略,并且阀门驱动摇杆35总是被低速进气凸轮33直接驱动。 Although details are not shown, in the structure, the low-side switching structure (mainly switching operation member 40a and a cam follower rocker 60) is omitted, and the valve drive rocker 35 is always low speed intake cam 33 driven directly. 因此,当只有高速侧切换结构被留下时,两级切换能在低速模式(正常)和高速模式之间被进行。 Thus, when only the left-speed switching structure, two switching can be performed between the low-speed mode (Normal) and a high speed mode.

[0102] 排气侧有这样的结构,其中不驱动阀门的机构和部分被从左组7a中的排气摇杆臂模块19上移除,也就是,其中只有阀门驱动摇杆90总是被排气凸轮直接驱动。 [0102] the exhaust side has a structure which is not removed on the drive mechanism and the valve 19 in the left portion 7a exhaust rocker arm module groups, i.e., wherein only the valve drive rocker 90 is always direct drive exhaust cam.

[0103] 右组7b也有这样的结构,其中当只有油路26b被留下,用于汽缸暂停模式的油路26a和27a被省略。 [0103] right panel 7b has a structure in which when only the oil passage 26b is left, are omitted for the oil passage 26a and the cylinder pause mode 27a. 换句话说,在右组7b的结构中,带有高速进气凸轮的阀门驱动和带有低速进气凸轮的阀门驱动的两级切换可以在进气系统中被进行,并且只有带有排气凸轮的阀门驱动(正常模式)能够在排气系统中被进行。 In other words, in the right panel 7b of the structure, with the high-speed intake cam and the valve drive with two switching the low speed intake cam driven valve in the intake system can be performed, and only with the exhaust gas valve drive cam (normal mode) can be performed in the exhaust system.

[0104] 另一方面,如图1到3所示,用于汽缸暂停模式,作为模式切换油控阀门的油控阀门120 (以下被称为OCV 120)被设置在左组7a的前端,当发动机被安装在发动机舱中,左组7a是前侧(对应于汽车车身端侧)。 [0104] On the other hand, as shown in FIG. 1 to 3, a cylinder pause mode, the mode switching as an oil control valve of the oil control valve 120 (hereinafter referred to as the OCV 120) is provided at the front end 7a of the left group, when the engine is mounted in the engine compartment, 7a is a front left-side group (corresponding to the vehicle body side end). OCV 120在本发明中被定义为第二油控阀门。 OCV 120 is defined as the second oil control valve in the present invention.

[0105] 用于高速模式的油控阀门121(以下被称为OCV 121)被设置在右组7a的后端,右组7a是后侧的。 [0105] high-speed mode for oil control valve 121 (hereinafter referred to as the OCV 121) is provided at the right rear end 7a of the group, group 7a is the right rear side. OCV 120和121所附接的组端是这样的区域,其面向由左右组7a和7b之间的偏移产生的前侧偏移空间Ll和后侧组偏移空间L2,因此OCV 120和121被容纳于组偏移空间Ll和L2中。 120 and 121 attached OCV end group is a region, which faces the group offset between right and left 7a and 7b generate offset front and rear space group offset space Ll L2, so OCV 120 and 121 is accommodated in the space group offset Ll and L2. OCV 121在本发明中被定义为第一油控阀门。 OCV 121 is defined as the first oil control valve in the present invention.

[0106] OCV 120和121中,用于汽缸暂停模式的附接在左组7a上的OCV 120包括,例如如图3、9和10所示,基础部件160,推进支撑部件161,和控制阀门162。 [0106] OCV 120 and 121, attached to the cylinder connected to the pause mode of the left group 7a OCV 120 comprises, for example, as shown in FIG. 3, 9 and 10, base member 160, to promote the support member 161, and a control valve 162. 基础部件160附接在左组7a的端面。 Base member 160 is attached to the left end surface 7a of the group. 推进支撑部件161从推进方向支撑形成在基础部件160中并从组端突出的凸轮轴端。 Advancing the support member 161 from the advancing direction of the support member 160 is formed in the base and projecting from the end of the camshaft end of the group. 控制阀门162被组装入基础部件160。 Control valve 162 is assembled into the base member 160.

[0107] 电磁伺服阀门被用作控制阀门162。 [0107] The servo solenoid valve 162 is used as a control valve. 所述伺服阀门被这样配置,例如,外壳163(显示在图3和10中)整体地形成在基础部件160上面,线轴164(显示在图10中)容纳于壳体163中。 Said servo valve is configured such that, for example, the housing 163 (shown in FIGS. 3 and 10) integrally formed in the top 160, the bobbin base member 164 (shown in FIG. 10) accommodated in the housing 163. 也就是,控制阀门162有这样的结构,其中打开和关闭操作通过线轴164的位移被进行。 That is, the control valve 162 has a structure in which the opening and closing operations are performed by the displacement of the spool 164.

[0108] 然而,从外壳163向上突出的部件是驱动线轴164的螺线管164a。 [0108] However, projecting upwardly from the housing member 163 is a solenoid driven spool 164a 164 a. 基础部件160 的每一部件以例如螺栓165的固定构件被固定至在左组7a前端的每一部件,螺栓165将整个OCV 120附接在作为汽缸暂停组的左组7a的外壁表面。 Each member of each base member 160 in a fixed member such as a bolt member 165 is fixed to the front end 7a of the left group, the bolts 165 the whole OCV 120 is attached to the outer wall surface of the left suspension cylinders 7a group of the group.

[0109] 如图9和10的详细图示,用于汽缸暂停模式的作为模式切换油泵的油泵170被整体地配备于OCV 120中。 [0109] shown in detail in FIG. 9 and 10, an oil pump for cylinder pause mode as a mode switch pump 170 is integrally provided in OCV 120. 凸轮轴驱动的泵,例如柱塞泵,被用作油泵170。 A camshaft driven pump, a plunger pump, for example, are used as pump 170.

[0110] 柱塞泵包括,例如,泵驱动凸轮171 (在此情况下,三个凸轮被等间隔排列)和柱塞172。 [0110] piston comprises, e.g., a pump drive cam 171 (in this case, three cam is arranged at equal intervals) and a plunger 172. 凸轮171形成在从组端部突出的凸轮轴25的端部的外圆周表面上。 The cam 171 is formed on the outer circumferential surface of the end portion projecting from the end portion of the group 25 of the camshaft. 柱塞172被配备于外壳163中(定义OCV 120的轮廓)。 The plunger 172 is provided in the housing 163 (the contour definition OCV 120).

[0111] 特别是,在柱塞172中,汽缸部件173被配备在位于凸轮轴周围的外壳部件(放置泵驱动凸轮25的区域)到外壳上部件的范围内。 [0111] In particular, the plunger 172, the cylinder member 173 is provided in the housing member positioned around a cam shaft (cam 25 is placed in the pump drive region) in the range of the upper housing member. 柱塞174、弹簧构件200和蓄能器172a被并入汽缸部件173。 The plunger 174, the spring member 172a and the accumulator 200 are incorporated in the cylinder member 173. 弹簧构件200使柱塞174挤压泵驱动凸轮171。 The spring member 200 of the plunger 174 pressing the pump drive cam 171. 单向阀门175与排放通路174a和柱塞174的吸入通路174b相连接以分别构成排放部件和吸入部件。 Check valve inlet passage and the discharge passage 174a 174b 175 and the plunger 174 is connected to the suction and discharge element constituting each member.

[0112] 以此结构,油泵170被排列在最靠近控制阀门162的点上,油压可以最少损失地被引到控制阀门162上。 [0112] In this structure, the oil pump 170 is arranged at a point closest to the control valve 162, the hydraulic pressure can be minimal loss introduced to the control valve 162. 显然,在油泵170中,每次柱塞174越过凸轮轴25的泵驱动凸轮171 时将进行抽吸操作。 Obviously, the pump 170, the plunger 174 each time the camshaft 25 over the pump sucking operation will be the driving cam 171. 以油泵170的安装结构,油泵170和OCV 120被配备于左组7a的前端。 In the mounting structure of the pump 170, the pump 170 and the OCV 120 is provided at a front end 7a of the left group.

12[0113] 因此,作为OCV 120主要部分的控制阀门162被暴露至发动机机身1的外面。 12 [0113] Thus, the engine 162 is exposed to the outside of the body 1 as a main part of a control valve 120 OCV. 此外,控制阀门162与油泵170 —起暴露在发动机舱R的尾部,也就是,在前部,当发动机间隔R打开时,控制阀门162所处的明显和靠近的位置。 Further, the control valve 162 and pump 170-- exposed from the tail engine compartment R, i.e., the front portion, when the distance R from the engine to open, close and clear the control position of the valve 162 is located.

[0115] 控制阀门162和油泵170径向地(相对凸轮轴25)向汽缸盖6的上面突出从而方便了维护。 [0115] Control valves 162 and pump 170 are radially (relative to the camshaft 25) projecting above the cylinder head 6 to thereby facilitate the maintenance.

[0116] 类似左组7a,例如,OCV 121包括基础部件180、推动支撑部件(未显示)、和例如电磁伺服阀门的控制阀门182。 [0116] Similarly left panel 7a, e.g., OCV 121 includes a base member 180, pushing the support member (not shown), such as control valves and the servo solenoid valve 182. 基础部件180附接在右组7b的端表面上。 Connected to base member 180 attached on the end surface 7b of the right group. 推动支撑部件从推动方向支撑形成在基础部件180上而从组端突出的凸轮轴端。 Pushing direction from the pushing support member is supported on the base member 180 is formed from the projecting end of the camshaft end group. 控制阀门182被并入推动支撑部件和基础部件180。 Control valve 182 is incorporated into the base member and pushes the supporting member 180.

[0117] 类似OCV 120,OCV 121用螺栓固定。 [0117] Similarly OCV 120, OCV 121 is fixed with bolts. 除了控制阀门182之外,OCV 121包括储蓄来自将发动机油从油盘抽起的润滑油泵(未显示)的油压的蓄能器183,和蓄能器183中储蓄的油通过其被引到控制阀门182的入口(未显示)的通路(未显示)。 In addition to the control valve 182 outside, OCV 121 from a lubricating oil pump including savings taken out of the engine oil from the oil pan (not shown) of the hydraulic accumulator 183 and the accumulator 183 through which savings is introduced to the oil a control valve inlet passage 182 (not shown) (not shown).

[0118] 切换到高速模式所需要的油压可以通过蓄能器183中的油或来自根据发动机转速被驱动的润滑油泵的油来保证。 [0118] high-speed mode is switched to the oil pressure required for the engine speed may be driven to ensure the lubricant pump oil from the accumulator 183 through the oil or. (在高发动机转速范围内,进行切换到高速模式) (In the high engine speed range to a high speed switching mode)

[0119] 如图2和7所示,OCV 120的控制阀门162的出口(未显示)通过形成在汽缸盖6(左组7a)中的通路153与摇杆轴27 (排气侧)的油路27a相连通从而将油压以最短的路径施加到可调节阀门系统17a。 [0119] As shown in FIGS. 2 and 7, OCV control valve 120 of the outlet 162 (not shown) 6 (left panel 7a) 27 (exhaust side) of the rocker shaft passage 153 is formed by a cylinder cover oil communicating passage 27a so that the hydraulic pressure is applied to the shortest path to the adjustable valve system 17a. 摇杆轴26的油路26a与形成在汽缸盖6中的返回通路153a(只显示在图7中)相连通。 An oil passage 26a of the rocker shaft 26 is formed in the cylinder head and the return path 153a 6 (only shown in FIG. 7) in communication.

[0120] 如图2所示,OCV 121的控制阀门182的出口通过形成在右组71b的汽缸盖6中的通路6b与进气侧摇杆轴26的油路26b (右组7b)相连通。 [0120] 2, the outlet control valve OCV 121 is formed in the oil passage 182 through the right panel 71b of the cylinder head 6, the intake passage 6b and the rocker shaft 26 side 26b (right panel 7b) communicating . 通路6b在本发明中被定义为油路。 It is defined as the oil passage 6b in the present invention. 如图2所示,OCV 121的控制阀门182的排放部件经过与左右组7a和7b相连接的延迟管部件155与左组7a的摇杆轴26 (进气侧)的油路26b相连通,入口156a位于汽缸盖6 (左组7a)的端,通路156与入口156a相连通。 2, the passage control valve OCV delay tube member 121 through the discharge member 182 and the left and right groups 7a and 7b are connected with the left group 155 of the rocker shaft 7a 26 (intake side) 26b of communicating, the inlet end 156a of the cylinder head 6 (left panel 7a), the passage 156 communicating with the inlet 156a.

[0121] 以该结构,当控制阀门182(油控阀门121)被操作,油压从蓄能器183被施加到左右组7a和7b的可调节阀门系统17a和17b,将组7a和7b的运转从正常模式切换到高速模式。 [0121] In this structure, when the control valve 182 (oil control valve 121) is operated, the hydraulic accumulator 183 is applied to the left and right groups 7a and 7b adjustable valve systems 17a and 17b from the group 7a and 7b operation switching from the normal mode to the high speed mode. 当控制阀门162(0CV 120)被操作,油压从凸轮轴从动油泵170被施加到可调节阀门系统17a,左组7a的运转将切换到左组7a停止的汽缸暂停模式。 When the control valve 162 (0CV 120) is operated, hydraulic 17a, the operation of the left group of switches 7a camshaft driven oil pump 170 is applied to the valve system can be adjusted to the left from the group of the cylinders 7a stop pause mode.

[0122] OCV 120和121的控制阀门162和182与控制单元122 (由,例如,微计算机形成) 相连接。 [0122] OCV control valves 120 and 162 and 182 and 121 of the control unit 122 (made, e.g., a microcomputer formed) is connected. 例如,控制单元122有根据取决于汽车运行状态预先设置的图表的功能。 For example, the control unit 122 has a function chart according to the operation of the vehicle depending on preset state. 在所述功能中,OCV 120和121的控制阀门162和182被关闭直至在发动机正常运转的预定发动机转速范围(正常驱动状态),只有OCV 121的控制阀门182从超过预设转速范围的高发动机转速范围被打开,并且只有OCV 120的控制阀门162在稳定运行条件无大输出地被满足的汽缸暂停范围中被打开。 In the function, the control valve 120 and the OCV 121 162 and 182 are closed until the engine in the normal operation of the predetermined engine speed range (normal driving state), only the control valve 182 of the OCV 121 from exceeding a predetermined high engine speed range speed range is opened and the valve 120 controls only the OCV 162 is opened in the cylinder suspended without large range of steady state operating conditions to be satisfied in the output.

[0123] 以此结构,进气侧切换机构69a和79a以及排气侧切换机构97可以通过可调节阀门装置根据汽车(交通工具)的运行状态在运行模式之间做切换。 [0123] In this structure, the intake-side switching mechanisms 69a and 79a and the exhaust-side switching mechanism 97 via an adjustable valve means to do switching between operating modes in accordance with automobiles (vehicle) operating state. [0124] 在此实施例中,发动机机身1,可调节阀门系统17a,可调节阀门系统17b,0CV120, 和OCV 121组成在本发明中被定义为第一交叉部的可调节阀门装置300。 [0124] In this embodiment, the engine body 1, the adjustable valve system 17a, the adjustable valve system 17b, 0CV120, composition and OCV 121 is defined as a first intersecting portion in the present invention, the adjustable valve means 300.

[0125] 参考图11和14说明可调节阀门系统17的行为。 [0125] with reference to FIGS. 11 and 14 illustrate the behavior of the adjustable valve system 17. 当根据汽车的运行状态,用于进行低速模式的命令被提供至控制单元122时,控制单元122使OCV 120和121的控制阀门162和182保持关闭。 When the operating state of the vehicle, for the low speed mode command is supplied to the control unit 122, the control unit 122 so that the control valve OCV 120 and 121 162 and 182 remain closed.

[0126] 也就是,油压没有在油路26a,26b和27a中行动。 [0126] That is, there is no action in the hydraulic oil 26a, 26b and 27a. 如图11中的实线所示,左组7a 的切换操作部件40a (进气)的窗口44被活塞46 (通过压缩弹簧47的弹力)阻塞。 The window 11 shown by the solid line, the left group 7a switching operation member 40a (inlet) 44 of the piston 46 is blocked (by the compression spring 47). 切换操作部件40b (进气)的窗口50被打开(通过压缩弹簧54的弹力),如图12的实线所示。 Window switching operation member 40b (inlet) 50 is opened (by the compression spring 54) is a solid line 12 shown in FIG.

[0127] 如图13所示,左组7a的切换操作部件98 (排气)的窗口100被活塞102 (通过压缩弹簧103的弹力)阻塞。 [0127] As shown, the left group 7a switching operation member 98 (the exhaust gas) 13 by the piston 102 of the window 100 is blocked (by compression spring 103). 然后,在左组7a中,进气侧凸轮跟随摇杆60(低速)和排气侧凸轮跟随摇杆80靠近活塞46和102地摇摆。 Then, in the left panel 7a, the intake-side rocker cam follower 60 (low) and the exhaust-side rocker cam follower 80 and piston 46 close to 102 sway.

[0128] 因此,在左组7a中,进气凸轮33 (用于低速)的位移从阀门驱动摇杆35通过摇杆臂37被传送到进气阀门13a和13b的杆端,从而驱动进气阀门13a和13b。 [0128] Accordingly, in the left panel 7a, the displacement of the intake cam 33 (for low speed) from the valve drive rocker and the rod end 35 13a is transmitted to the inlet valve by a rocker arm 37 13b so as to drive the intake valves 13a and 13b. 排气凸轮32的位移也从阀门驱动摇杆90的连接臂95通过臂93被传送到排气阀门15a和15b的杆端,从而驱动排气阀门15a和15b。 Displacement of the exhaust cam 32 also drives the rocker arms 95 is connected from the valve 90 is communicated to the exhaust valve through an arm 15a and an end 15b of the rod 93, thereby driving the exhaust valves 15a and 15b.

[0129] 在右组7b的进气侧,类似左组7a,只有被传送到阀门驱动摇杆35的低速进气凸轮(未显示)的位移被传送到进气阀门(未显示),从而驱动进气阀门。 [0129] the right side of the intake 7b of the group, the group is similar to left 7a, is transferred to the valve drive is transmitted only low-speed intake rocker cam (not shown) is supplied to the displacement of the intake valve 35 (not shown), thereby driving inlet valve. 在排气侧,排气凸轮(未显示)的位移通过阀门驱动摇杆90被直接传递到排气阀门,从而驱动排气阀门。 On the exhaust side, the displacement of the exhaust cam (not shown) through the valve drive rocker 90 is directly transmitted to the exhaust valve, thereby driving the exhaust valve.

[0130] 因此,左右组7a和7b在图19的低速凸轮和排气凸轮的组合带来的低速模式下被操作(直到预定发动机转速范围:正常运转)。 [0130] Thus, the left and right groups 7a and 7b are operated at a low speed of the combination of FIG. 19 and exhaust cams to bring the low-speed mode (engine speed up to a predetermined range: the normal operation).

[0131] 当发动机由于例如要求高输出的加速的运行而变为超过预定转速范围的高转速范围时,控制单元122仅打开用于高速模式的OCV 121的控制阀门182。 [0131] When the engine acceleration operation due, for example, requires a high output speed range becomes the high speed exceeding the predetermined range, the control unit controls the valve 122 is opened only for the OCV 121 of 182 high-speed mode. 这使储蓄在蓄能器183中的高油压或来自由曲柄输出以高转速驱动的润滑油泵的高油压能通过管构件155和通路156被引到左组7a的油路26b和右组7b的油路26b (进气侧摇杆轴)。 This allows savings in the high oil pressure or the accumulator 183 to output a crank consisting of a lubricant pump driven at a high speed by the high oil pressure tube member 155 and passage 156 is led to the oil passage 26b of the left group and right 7a groups 7b oil passage 26b (intake side rocker shaft).

[0132] 因此,切换所需要的油压被施加到左组7a或右组7b的(进气侧)切换操作部件40b的销子55上。 [0132] Thus, the hydraulic pressure required to switch is applied to (the intake side) of the left group or right group 7a and 7b of the switching operation member 40b on the pin 55. 这样,被销子55向上驱动的活塞53阻塞了窗口50,如图12的1长2短线所示。 Thus, the drive pin 55 upwardly of the piston 53 blocking the window 50, as shown in FIG short length of 2 to 12. 然后,如图12的1长2短线所示,左右组7a和7b的进气侧凸轮跟随摇杆70当紧贴在活塞53上时被摇摆。 Then, as a short length 12 shown in FIG. 2, left and right groups 7a and 7b on the intake side rocker cam follower 70 when the piston 53 is in close contact when swinging.

[0133] 因为高速进气凸轮30的外形被设定得比低速进气凸轮33的大,只有来自凸轮跟随摇杆70的进气凸轮30 (用于高速)的位移从阀门驱动摇杆35被传送到进气阀门13a和13b。 [0133] Since the high-speed intake cam 30 is set to be larger than the outer shape of the intake low cam 33 is large, only the displacement of the rocker from the cam follower 70, the intake cam 30 (for high speed) from the valve driving rocker 35 is transmitted to inlet valve 13a and 13b. 也就是,左右组7a和7b的进气阀门13a和13b只被高速进气凸轮30驱动。 That is, the left and right groups 7a and 7b of the intake valves 13a and 13b are driven only high-speed intake cam 30.

[0134] 排气凸轮32的位移从凸轮跟随摇杆80被传送到阀门驱动摇杆90的连接臂95,从而持续驱动左组7a的排气阀门15a和15b。 [0134] displacement of the exhaust cam follower 32 from the rocker cam 80 is transmitted to the valve driving rocker arms 95 is connected 90 to continuously drive the exhaust valve 7a, left panel 15a and 15b. 右组7b的排气阀门保持以相同动作运行。 Right panel 7b of the exhaust valve is kept running in the same operation. 因此,左右组7a和7b切换到由图19的高速凸轮和排气凸轮的组合带来的高速模式。 Thus, the left and right groups 7a and 7b are caused by a combination of switching to the high speed cam and an exhaust cam 19 of the high-speed mode of FIG.

[0135] 当汽车进入燃料消耗减少的运行状态,例如,低速和中速运行或空档,控制单元122进行汽缸暂停模式(用于减少燃料消耗的模式)。 [0135] When the car enters the operating state of the fuel consumption reduction, e.g., low and medium speed running or neutral, the control unit 122 performs the cylinder pause mode (mode for reducing fuel consumption). 也就是,控制单元122进行打开用于汽缸暂停模式的OCV 120的控制阀门162的控制。 That is, the control unit 122 for opening the OCV for cylinder control valve 120 a pause mode control 162.

[0136] 在这一点,因为用于汽缸暂停模式的附接至OCV 120上的油泵170通过凸轮轴25 的转动(双曲柄轴)被驱动,即使在低发动机转速状态下(甚至空档),换句话,即使在蓄能器172a中不保证油压,足以驱动可调节阀门系统17a的切换的油压也被保证。 [0136] At this point, since the pause mode for attachment of the cylinder is coupled to the oil pump 120 OCV 170 is driven by the rotation (double crankshaft) 25 of the cam, even at low engine speed state (even neutral), in other words, even in the accumulator 172a is not guaranteed hydraulic pressure sufficient to drive the adjustable hydraulic switching valve system 17a is also guaranteed.

[0137] 如图2所示,油泵170的油压通过控制阀门162的开-闭端口被提供到通路153, 这将油压引到摇杆轴27 (排气侧)的油路27a。 [0137] As shown, the hydraulic pump 170 through a valve 162 controlling the second opening - closing port is provided to passage 153, which will lead to the oil passage 27a rocker shaft 27 (exhaust side). 然后,油路27a的油压被引到左组7a中的摇杆轴26 (进气侧)的油路26a,这使每个切换操作部件40a的活塞46升高。 Then, the hydraulic pressure of the oil passage 27a is introduced to 26 (intake side) of the oil passage 26a of the rocker shaft 7a of the left group, each of which makes the switching operation member 40a of the piston 46 increases.

[0138] 因此,进气侧切换操作部件40a的窗口44被打开。 [0138] Thus, the switching operation of the intake-side member 40a of the window 44 is opened. 因为油压不在切换操作部件40b上行动,窗口50被打开(参看图12)。 Since the oil pressure switching operation member 40b is not in operation, window 50 is opened (see FIG. 12).

[0139] 因此,在左组7a中,凸轮跟随摇杆60 (进气:低速)和凸轮跟随摇杆80 (排气)在冲击空气时被摇摆。 [0139] Accordingly, in the left panel 7a, the cam follower rocker 60 (intake: low) and a cam follower rocker 80 (exhaust gas) is air swing upon impact. 这中断了用于驱动阀门的驱动力向阀门驱动摇杆35和90(进气和排气)的传递。 This interrupts the transmission of driving force for driving the valve drive rocker 35 and the valve 90 (intake and exhaust) of.

[0140] 在这一点,在右组7b的进气可调节阀门装置20和排气可调节阀门装置21中,进气凸轮的位移持续地被传送到进气阀门而排气凸轮的位移被持续地传送到排气阀门。 [0140] is sustained at this point, the right set of intake valve 7b of the adjustable means 20 and the exhaust valve means 21 can be adjusted, the intake cam is continuously sent displacement of the inlet valve and the exhaust cam displacement transmitted to the exhaust valve. 因为这个原因,发动机切换到左组7a被暂停的汽缸暂停模式。 For this reason, the engine is switched to the left suspension cylinder group 7a pause mode.

[0141] 因为在汽缸暂停模式的运行中,汽缸暂停模式的范围被凸轮轴从动油泵170加宽了,汽缸暂停模式的频率被增加。 [0141] Since the operating cylinders in the pause mode, a pause mode range of cylinder oil pump driven by the camshaft 170 is widened, the frequency is increased cylinder pause mode. 因此,进行包括油泵170的OCV 120的维护的机会被增加。 Therefore, opportunities include maintenance OCV oil pump 170 120 is increased.

[0142] 下面说明维护。 [0142] The following describes maintenance. 假设OCV 120和油泵170的维护被进行。 Suppose OCV 120 and maintain the oil pump 170 is performed. OCV 120和油泵170都被附接至发动机机身1的外表面。 OCV 120 and pump 170 are attached to the outer surface of the body 1 of the engine.

[0143] 因为这个原因,当发动机舱R—旦被打开,包括油泵170的整个OCV 120呈现在发动机舱R中。 [0143] For this reason, when the nacelle is opened R- denier, the oil pump 170 includes the entire OCV 120 R is present in the engine compartment. 这满足了在发动机机身外侧对呈现出的的OCV 120和油泵170进行维护。 This satisfies the maintenance of showing the OCV 120 and 170 in the pump body outside of the engine.

[0144] 因此,可以对控制阀门162和油泵170进行维护而不需要麻烦的拆卸发动机机身1的零件的工作。 [0144] Thus, the control can maintain the valve 162 and pump 170 without requiring disassembly of the engine body work parts 1 troublesome.

[0145] 另外,OCV 120和油泵170附接至排布在作为明显和近手位置的汽缸盖端(排列在发动机舱R上部中的发动机机身部件),因此,可以在OCV 120和油泵170中容易地进行维护。 [0145] Furthermore, OCV 120 and 170 attached to the pump arrangement can thus be in the OCV 120 and pump 170 as visible and the near end of the hand position of the cylinder head (arranged at the upper portion of the engine nacelle body element R), in easy maintenance.

[0146] 特别是,油泵170被配备于OCV 120的外壳163内,这使油泵170最接近控制阀门162(切换部件)。 [0146] In particular, the oil pump 170 is provided within the housing 163 OCV 120, oil pump 170 which is closest to the control valve 162 (switching means). 因此,油压可以有效地被给至可调节阀门系统17a而减少损失。 Accordingly, the hydraulic pressure can be effectively given to the adjustable valve system 17a and reduce losses. 此外,油泵170构成了OCV 120的一部分,因此,油泵170的简化被实现。 In addition, the oil pump 170 constitutes a part of the OCV 120, therefore, the oil pump 170 is a simplified implementation.

[0147] 在V型发动机中,当OCV 120和油泵170被设置在进行汽缸暂停模式的组7a的汽缸盖端处的外壁表面中时,通过利用V型发动机的特点,OCV 120和油泵170被排布在近手的位置。 [0147] In the V-type engine, when the OCV 120 and the oil pump 170 is provided during the pause mode group 7a cylinders of the cylinder head at the end of the outer wall surface, by utilizing the characteristics of the V-type engine, the oil pump 170 and the OCV 120 is arranged in a position close to hand. 这实现了OCV 120和油泵170的方便维护。 This enables convenient OCV 120 and 170 of the oil pump maintenance.

[0148] 特别是,当附接了OCV 120的左组7a横向地安装在发动机舱内,左组7a被排列在汽车车身端侧(实施例的前侧)。 [0148] In particular, when the attachment of the OCV 120 of the left group 7a is mounted transversely in the engine compartment, the left group 7a are arranged at the vehicle body end side (front side embodiment). 结果,OCV 120和油泵170在维护时可以被马上清楚地识别出来。 Results, OCV 120 and pump 170 can now be clearly identified during maintenance. OCV 120和油泵170也被排列在最近手的位置。 OCV 120 and pump 170 are also arranged in the last position of the hand. 这给了OCV 120和油泵170高维护属性。 This gives the OCV 120 and pump 170 high-maintenance properties.

[0149] 类似地,当OCV 120和油泵170在纵向安装发动机中被排列在汽车车身端侧,维护的方便性也可以被改进。 [0149] Similarly, it is also convenience can be improved when the oil pump 170 and the OCV 120 is mounted in the longitudinal direction are arranged in the engine side of the vehicle body side, maintenance. 当OCV 120和油泵170被排列在汽车车身前侧,维护的方便性被 When convenience OCV 120 and pump 170 are arranged on the front side of the vehicle body, to be maintained

进一步改进。 Further improvements.

[0150] 只有通过在左右组7a和7b中普遍使用的OCV 121才能进行切换到高速模式,这使高速模式和汽缸暂停模式之间的切换只能通过最少数的0CV,即,分别排列在组7a和7b 中的OCV 120和121来进行。 [0150] Only the high-speed mode is switched to the OCV 121 can be commonly used in the left and right groups 7a and 7b, which makes switching between the high speed mode and a pause mode of the cylinder only through a few of the most non-zero CV, i.e., they are arranged in groups 7a and 121 7b in OCV 120 and to perform. [0151] 因此,昂贵的OCV的数量可以被减少,因此,发动机成本和发动机重量可以被减少。 [0151] Thus, the number of expensive OCV can be reduced, and therefore, the cost of the engine and the engine weight can be reduced.

[0152] 因为OCV 120和121被排列在变为V型发动机内盖空间的组偏移空间Ll和L2内, OCV 120和121可以被紧凑地组装至发动机。 [0152] Because the OCV 120 and the cover 121 are arranged in the space becomes a V-type engine and a set of offsets within the space Ll L2, OCV 120 and 121 may be assembled to a compact engine. 因此,可以抑制发动机的尺寸增加。 Thus, increasing the size of the engine can be suppressed.

[0153] 另外,用于汽缸暂停模式的OCV 120未被排列在组内而被排列在组端的外表面中,因此,容易进行对OCV 120的维护(因为不需要拆卸不同的部分来将OCV 120暴露到组的外表面)。 [0153] Further, the OCV pause mode for the cylinders 120 are not arranged in a group are arranged on the outer surface of the end groups, and therefore, easy maintenance of the OCV 120 (due to different portions of the need to disassemble the OCV 120 exposed to the outer surface of the group).

[0154] 特别是,与OCV 121相比,用于汽缸暂停模式的OCV 120被排列在汽车车身端侧(实施例中的汽车车身前侧),与发动机安装在发动机舱内的姿态无关(横向或纵向安装的发动机)。 [0154] In particular, compared to the OCV 121, OCV pause mode for the cylinder 120 is arranged at the vehicle body end side (vehicle body front side of the embodiment in the embodiment), the posture of the engine mounted in the engine compartment of independent (lateral or longitudinally mounted engine). 因此,在维护中,用于汽缸暂停模式的比OCV 121有更高维护频率的OCV 120位于明显和近手的位置,维护属性高。 Thus, during maintenance, than the OCV 121 to the cylinder to maintain the pause mode has a higher apparent and located near the position of the hand 120 of the OCV frequency, high maintenance property. 根据本实施例,用于汽缸暂停模式的OCV 120排列于汽车车身前侧,这进一步提高了维护的方便性。 OCV embodiment according to the present embodiment, the pause mode for the cylinders 120 are arranged to the front side of the vehicle body, which further improves the ease of maintenance.

[0155] 本发明不只限于所述实施例,多种变更和修改可以被产生而不超出本发明的范围。 [0155] The present invention is not limited to the embodiments, various changes and modifications may be produced without departing from the scope of the present invention.

[0156] 虽然实施例中可调节阀门机构使用活塞结构切换到汽缸暂停模式,作为例子,另外的切换到汽缸暂停模式的可调节阀门机构可能被使用。 [0156] While the embodiments using the adjustable valve mechanism is switched to the cylinder piston arrangement pause mode, by way of example, additional switching to the pause mode the adjustable cylinder valve mechanism may be used.

[0157] 本领域技术人员将容易想到附加的优势和修改。 [0157] Those skilled in the art will readily envision additional advantages and modifications. 因此,在广泛的方面中的本发明不只限于这里所显示和描述的精确的细节和相应的实施例。 Thus, in broad aspect of the present invention is not limited to the shown and described herein precise details and the corresponding embodiments. 因此,多种修改可能被作出而不超出附加权利要求及其同等物所定义的本发明总体概念的精神和范围。 Accordingly, various modifications may be made without departing from the spirit and scope of the general concept of the present invention, the appended claims and equivalents as defined above.
