Description

一种新型发动机 技术领域
本发明涉及发动机技术领域，更具体地说，特别涉及一种新型发动机。
背景技术
发动机(Engine)是一种能够把其它形式的能转化为机械能的机器，最早诞生在英国，其既适用于动力发生装置，也可指包括动力装置的整个机器(如：汽油发动机、航空发动机)。其种类包括如内燃机(汽油发动机等)、外燃机(斯特林发动机、蒸汽机等)等。
其中内燃机应用较为普遍，内燃机按气缸排列方式不同可以分为单列式和双列式。单列式发动机的各个气缸排成一列，一般是垂直布置的，但为了降低高度，有时也把气缸布置成倾斜的甚至水平的；双列式发动机把气缸排成两列，两列之间的夹角小于180°称为V型发动机，若两列之间的夹角等于180°称为对置式发动机。对置发动机国外研究的较多，有对置活塞发动机和水平对置发动机，其活塞大多为上下运动的方式或者水平运动的方式。而活塞采用上下运动的方式会导致发动机上半部分润滑问题难解决，并且使发动机重心高。活塞采用水平运动的方式会导致活塞的上表面接触不到润滑油，造成活塞在缸体内润滑不均匀的情况发生，影响到活塞的使用寿命。为此，我们提出一种新型发动机来解决上述问题。
发明内容
本发明的目的是提出一种新型发动机，以解决现有技术中存在的问题。
为了实现上述目的，本发明采用了如下技术方案：
一种新型发动机，包括缸体，所述缸体的底部固定连接有固定板，所述固定板通过转轴连接有输出齿轮和传动齿轮，所述输出齿轮的两侧均与两个传动齿轮啮合连接，所述固定板上转动连接有曲轴，所述曲轴的外侧壁上分别固定套接有飞轮和驱动齿轮，所述驱动齿轮与传动齿轮啮合；所述曲轴通过联动机构连接有活塞，所述缸体上设置有与活塞对应的气缸，两个对应的所述气缸相通，对应的两个所述气缸呈倒V型设置，所述缸 体的顶部设置有火花塞、进气门和排气门。
优选地，所述联动机构包括连杆，所述活塞靠近曲轴的一侧设置有凹槽，所述凹槽的内侧壁转动连接有活塞销，所述活塞销和曲轴均通过转动套与连杆连接。
优选地，所述传动齿轮是输出齿轮数量的两倍。
优选地，两个所述曲轴的转动方向相同。
优选地，所述飞轮和驱动齿轮分别位于固定板的两侧。
本发明提供的技术方案可以包括以下有益效果：
1、本发明中，发动机的活塞运动轨迹为倾斜上下往复运动，重心低，能量转化率高；
2、本发明中，发动机具有水平对置发动机低振动的优点；
3、本发明中，发动机的活塞倾斜上下往复运动，解决了水平对置发动机润滑不良的问题；
4、本发明中，发动机气缸呈倒V型设置，解决了对置活塞发动机气缸上下设置时发动机上半部分润滑困难的问题；
5、本发明中，两个活塞设置在一个腔体内比单活塞的发动机降低了缸内爆压。
附图说明

图2为本发明提出的一种新型发动机的内部结构示意图；
图3为本发明提出的一种新型发动机中飞轮、曲轴、连杆、固定板、驱动齿轮和转动套的连接结构示意图。
图中：1、缸体；2、固定板；3、转轴；4、飞轮；5、传动齿轮；6、输出齿轮；7、火花塞；8、进气门；9、排气门；10、活塞；11、活塞销；12、转动套；13、连杆；14、驱动齿轮；15、曲轴；16、气缸。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
参照图1-图3，一种新型发动机，包括缸体1，缸体1的底部固定连 接有固定板2，固定板2通过转轴3连接有输出齿轮6和传动齿轮5，输出齿轮6的两侧均与两个传动齿轮5啮合连接，固定板2上转动连接有曲轴15，曲轴15的外侧壁上分别固定套接有飞轮4和驱动齿轮14，驱动齿轮14与传动齿轮5啮合；曲轴15通过联动机构连接有活塞10，缸体1上设置有与活塞10对应的气缸16，两个对应的气缸16相通，对应的两个气缸16呈倒V型设置，缸体1的顶部设置有火花塞7、进气门8和排气门9。火花塞7、进气门8和排气门9均固定在缸体1的顶部，且与气缸16相通。其中，联动机构安装在曲轴15上，使得活塞10可以在气缸16内往复运动，从而带动输出齿轮6转动。
进一步地，联动机构包括连杆13，活塞10靠近曲轴15的一侧设置有凹槽，凹槽的内侧壁转动连接有活塞销11，活塞销11和曲轴15均通过转动套12与连杆13连接。
进一步地，传动齿轮5是输出齿轮6数量的两倍。
进一步地，两个曲轴15的转动方向相同。
进一步地，飞轮4和驱动齿轮14分别位于固定板2的两侧。
进一步地，该发动机的活塞10数量为偶数，且不局限为两个。
进一步地，进气门8的数量和排气门9的数量也不局限为两个。
本实施例中，当发动机运行时，活塞10在缸体1的内部往复运动，活塞10往复运动带动曲轴15转动，由于曲轴15上的驱动齿轮14与传动齿轮5啮合，因此，传动齿轮5转动，又因为传动齿轮5与输出齿轮6啮合，所以，活塞10往复运动带动输出齿轮6快速转动。该发动机的活塞10运动轨迹为倾斜上下往复运动，重心低，能量转化率高，该发动机具有水平对置发动机低振动的优点，同时该发动机的活塞10倾斜上下往复运动，解决了水平对置发动机润滑不良的问题。
本实施例中，发动机气缸16呈倒V型设置，解决了对置活塞发动机气缸16上下设置时发动机上半部分润滑困难的问题。
本实施例中，两个活塞10设置在一个腔体内比单活塞的发动机降低了缸内爆压。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围 内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
