具体实施方式detailed description
本发明所述往复活塞内置链式连杆无死点发动机活塞连杆组,如图1所示,包括连杆4和活塞2,活塞2底部中空。活塞2底部的内腔11内设置活动套3,活动套3能沿内腔11内壁轴向运动。活塞2为活动套3提供导向使活动套3能沿内腔11的轴线往复移动。活动套3内设置第一固定轴5,第一固定轴5上铰接连杆4的小头。连杆4的小头的一侧设置拨块10。拨块10上开设凹槽或销孔6,凹槽或销孔6位于第一固定轴5一侧,凹槽或销孔6内配合设置推杆7的一端,推杆7的另一端铰接第二固定轴8,第二固定轴8安装在活塞2内。若拨块10上开设的为凹槽,则凹槽直接与推杆7配合,若开设的为销孔则通过一根销轴与推杆7铰接。The reciprocating piston of the present invention has a chain connecting rod without dead point engine piston connecting rod set. As shown in FIG. 1 , the connecting rod 4 and the piston 2 are included, and the bottom of the piston 2 is hollow. A movable sleeve 3 is disposed in the inner cavity 11 at the bottom of the piston 2, and the movable sleeve 3 can move axially along the inner wall of the inner chamber 11. The piston 2 provides guidance to the movable sleeve 3 so that the movable sleeve 3 can reciprocate along the axis of the inner chamber 11. The first fixed shaft 5 is disposed in the movable sleeve 3, and the small head of the hinge link 4 is fixed on the first fixed shaft 5. A dial 10 is provided on one side of the small head of the connecting rod 4. A groove or a pin hole 6 is defined in the dial block 10, and a groove or pin hole 6 is located on one side of the first fixed shaft 5, and one end of the push rod 7 is fitted in the groove or the pin hole 6, and the other end of the push rod 7 is hinged. The second fixed shaft 8 is mounted in the piston 2. If the groove is formed in the dial block 10, the groove directly engages with the push rod 7. If the pin hole is opened, the pin 7 is hinged to the push rod 7.
作功行程之初,高温燃气对活塞2端面作功,活塞2通过推杆7对连杆4一侧施力,由于活动套3为连杆4的小头部提供摆动的支点,因此,活塞作功时能强制连杆4摆动以越过死点位置,即消除死点。因连杆4的小头部摆动而造成的第一固定轴5和第二固定轴8之间的距离变化,由活动套3相对活塞2上下移动而弥补。At the beginning of the power stroke, the high temperature gas works on the end face of the piston 2, and the piston 2 applies a force to the side of the link 4 through the push rod 7, since the movable sleeve 3 provides a pivot point for the small head of the connecting rod 4, therefore, the piston When working, the link 4 can be forced to swing to cross the dead point position, that is, to eliminate the dead point. The change in the distance between the first fixed shaft 5 and the second fixed shaft 8 due to the swing of the small head of the link 4 is compensated by the movable sleeve 3 moving up and down with respect to the piston 2.
活塞2通过活动套3内的第一固定轴5与连杆4连接,第一固定轴5磨损后,可以通过更换活动套3解决,避免造成浪费。而且,由于活塞2采用分体式结构,其强度更高,散热效果更好。活塞2、推杆7、活动套3和连杆4依次连接构成链式结构。The piston 2 is connected to the connecting rod 4 through the first fixed shaft 5 in the movable sleeve 3. After the first fixed shaft 5 is worn, it can be solved by replacing the movable sleeve 3 to avoid waste. Moreover, since the piston 2 adopts a split structure, its strength is higher and the heat dissipation effect is better. The piston 2, the push rod 7, the movable sleeve 3 and the connecting rod 4 are connected in sequence to form a chain structure.
使用时,活塞2装于气缸1内。气缸1和活塞2之间设置密封圈,密封圈安装在活塞2上部外壁内。所述密封圈为气环和油环。In use, the piston 2 is housed in the cylinder 1. A sealing ring is arranged between the cylinder 1 and the piston 2, and the sealing ring is installed in the upper outer wall of the piston 2. The seal ring is a gas ring and an oil ring.
为进一步避免死点的出现,还可采用以下技术方案:所述第二固定轴8的轴线过活塞2的中轴线,即,第二固定轴8的轴线与活塞2的中心线位于同一个竖直面上,第一固定轴5和拨块10分别位于曲柄的中心线所在的竖直面两侧,从而,可确保第二 固定轴8与推杆7下端中点的连线相对中心线有一定初始角度。当活塞2受力作功向下移动时,推杆7会产生推动连杆4摆动的分力,使连杆4沿第一固定轴5转动,避免连杆4位于上下止点时,连杆4出现死点。In order to further avoid the occurrence of a dead point, the following technical solution can also be adopted: the axis of the second fixed shaft 8 passes the central axis of the piston 2, that is, the axis of the second fixed shaft 8 is in the same vertical direction as the center line of the piston 2. On the straight surface, the first fixed shaft 5 and the dial block 10 are respectively located on both sides of the vertical plane where the center line of the crank is located, thereby ensuring the second The line connecting the fixed shaft 8 and the midpoint of the lower end of the push rod 7 has a certain initial angle with respect to the center line. When the piston 2 is forced to move downward, the push rod 7 generates a component force that pushes the swing of the connecting rod 4, so that the connecting rod 4 rotates along the first fixed shaft 5, and avoids the connecting rod 4 when the connecting rod 4 is at the top and bottom dead center. 4 appeared dead.
为使高温燃气对活塞端部施力更加集中有效,如图1所示,所述活塞2的顶端设有气槽12。In order to make the high temperature gas force more concentrated and effective on the end of the piston, as shown in FIG. 1, the top end of the piston 2 is provided with a gas groove 12.
本发明的技术方案并不限制于本发明所述的实施例的范围内。本发明未详尽描述的技术内容均为公知技术。 The technical solution of the present invention is not limited to the scope of the embodiments described in the present invention. The technical contents not described in detail in the present invention are all well-known techniques.
