Abstract

本发明公开了一种扇形齿轮齿条活塞发动机，包括齿条、主动齿轮组、从动齿轮组以及输出齿轮，齿条的上端与发动机的活塞连接，主动齿轮组包括扇形主动齿轮、输出主动齿轮以及主动齿轮轴。本发明与现有技术相比的优点在于：本方案利用齿轮与齿条的组合实现发动机功率输出，采用两个半圆扇形齿轮与齿条的组合配合活塞的往复行程进行输出，解决了传统发动机曲轴传动过程中的功率损失，实现了发动机的油耗热效的最大利用，因为该齿轮与齿条的输出力矩始终在作动过程中保持最大，而曲轴传动会随曲轴的转动改变输出力臂造成功率损失，所以会实现功率最大输出，并且由于采用了全线性圆轴传动，会大大改善发动机震动问题。

Description

一种扇形齿轮齿条活塞发动机 技术领域
本发明涉及发动机技术领域，具体为一种扇形齿轮齿条活塞发动机。
背景技术
发动机是汽车动力的源泉。迄今为止，除了为数不多的电动汽车之外，汽车发动机都是热能动力装置，简称热机。在热机中借助工质的状态变化，将燃料燃烧产生的热能转变成机械能。这种发动机通过曲柄连杆机构将活塞的往返直线运动转变成曲柄的旋转运动，进而将功率输出。在做功冲程中，发动机将燃料燃烧产生的热能转变成为推动活塞作往复式运动的机械能，再通过连杆带动曲轴作旋转运动；在其他冲程中，又由曲柄来驱动活塞作往复运动，从而实现换气和压縮的过程。
目前的发动机在通过曲轴传动时，传动力矩变化大，径向推力大，有死点，还存在很大的滑动摩擦损耗，使大量的能源被消耗浪费。
因此上述反映的技术问题是本领域技术人员亟待解决的问题。
发明内容
本发明的目的是提供一种扇形齿轮齿条活塞发动机。
为实现上述目的，采用如下技术方案：一种扇形齿轮齿条活塞发动机，包括齿条、主动齿轮组、从动齿轮组以及输出齿轮，所述齿条的上端与发动机的活塞连接，所述主动齿轮组包括扇形主动齿轮、输出主动齿轮以及主动齿轮轴，所述扇形主动齿轮与输出主动齿轮通过主动齿轮轴构成传动机构，所述从动齿轮组包括扇形从动齿轮、输出从动齿轮以及从动齿轮轴，所述扇形从动齿轮与输出从动齿轮通过从动齿轮轴构成传动机构，所述齿条的下端两侧分别于扇形从动齿轮以及扇形从动齿轮啮合，所述输出主动齿轮与输出齿轮啮合，所述输出从动齿轮与输出齿轮啮合。
本发明与现有技术相比的优点在于：本方案利用齿轮与齿条的组合实现发动机功率输出，采用两个半圆扇形齿轮与齿条的组合配合活塞的往复行程进行输出，解决了传统发动机曲轴传动过程中的功率损失，实现了发动机的油耗热效的最大利用，因为该齿轮与齿条的输出力矩始终在作动过程中保持最大，而曲轴传动会随曲轴的转动改变输出力臂造成功率损失，所以会实现功率最大输出，并且由于采用了全线性圆轴传动，会大大改善发动机震动问题。
附图说明
图1是本发明一种扇形齿轮齿条活塞发动机的结构示意图一。
图2是本发明一种扇形齿轮齿条活塞发动机的结构示意图二。
如图所示：1、齿条，2、输出齿轮，3、活塞，4、扇形主动齿轮，5、输出主动齿轮，6、主动齿轮轴，7、扇形从动齿轮，8、输出从动齿轮，9、从动齿轮轴。
具体实施方式
下面详细描述本发明的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。在本发明的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“内”、“外”、“竖向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
结合附图1-2，一种扇形齿轮齿条活塞发动机，包括齿条1、主动齿轮组、从动齿轮组以及输出齿轮2，所述齿条1的上端与发动机的活塞3连接，所述主动齿轮组包括扇形主动齿轮4、输出主动齿轮5以及主动齿轮轴6，所述扇形主动齿轮4与输出主动齿轮5通过主动齿轮轴6构成传动机构，所述从动齿轮组包括扇形从动齿轮7、输出从动齿轮8以及从动齿轮轴9，所述扇形从动齿轮7与输出从动齿轮8通过从动齿轮轴9构成传动机构，所述齿条1的下端两侧分别于扇形从动齿轮7以及扇形从动齿轮7啮合，所述输出主动齿轮5与输出齿轮2啮合，所述输出从动齿轮8与输出齿轮2啮合。
本发明在具体实施时，活塞3向下运动进行吸气，扇形从动齿轮7咬合齿条1，由飞轮带动活塞3吸气，扇形主动齿轮4无齿不进行工作。当活塞3到达下低点时，扇形主动齿轮4咬合，飞轮带动活塞3向上运动，进行气体压缩。当活塞3到达上顶点，燃油燃烧进行做功向下推动齿条1，带动扇形主动齿轮4输出，当活塞3到达下低点，扇形主动齿轮4与齿条1脱合，扇形从动齿轮7咬合，带动活塞3向上运动进行排气。当活塞3到达上顶点时，排气完毕，进行下一个往复行程。
扇形主动齿轮4与输出主动齿轮5同轴，通过主动齿轮轴6在扇形主动齿轮4输出时带动输出主动齿轮5旋转，从而带动输出齿轮2做功。而扇形从动齿轮7与输出从动齿轮8同轴，通过从动齿轮轴9在扇形从动齿轮7输出时带动输出从动齿轮8旋转，从而带动输出齿轮2做功。
由于所有齿轮同参数，所以活塞3行程不会错位，实现力矩的最大输出。
以上对本发明及其实施方式进行了描述，这种描述没有限制性，附图中所示的也只是本发明的实施方式之一，实际的结构并不局限于此。总而言之如果本领域的普通技术人员受其启示，在不脱离本发明创造宗旨的情况下，不经创造性的设计出与该技术方案相似的结构方式及实施例，均应属于本发明的保护范围。
