Abstract

本实用新型涉及的新型摩托车活塞包括头部、裙部3、裙部的销孔4;其特征在于:头部具有凹弧形顶端1。本实用新型虽然减小缸体内的压缩比,但由于增大了燃烧室的空间而能使燃烧完全充分,并能使活塞裙部和缸套的内导向好、配合更恰当;由于轴向上减小了活塞裙部的长度,使活塞的重量减轻、在缸体内的阻力减小;活塞裙部上增设的小孔能够使冷却和润滑效果更佳,并且对增加整个汽油机的功率提高有辅助的作用。

Description

新型摩托车活塞
本实用新型涉及涉及对摩托车汽油机部件的改进，特别是一种新型摩托车活塞。
现有技术中的摩托车汽油机活塞由头部、环(槽)、销孔及裙部组成。由于活塞的前端为凸起的球形头部，裙部的轴向长度较长，使其在工作中容易出现以下的现象：
1、由于球形头部的存在，造成燃烧室的燃烧空间减小，使燃油在燃烧室内燃烧不充分；
2、由于活塞的裙部与缸体套内表面配合不当，造成活塞的启动和工作阻力增加，容易使发动机的缸头部分产生发热，冷却效果差。
本实用新型的目的是提供一种能够增大汽油机燃烧室燃烧空间，而使燃烧更加充分，并且能减小或消除启动和工作阻力的新型摩托车活塞。
本实用新型的上述目的是通过这样的技术方案实现的，即一种新型摩托车活塞，包括头部、裙部、裙部的销孔；其特征在于：头部具有凹弧形顶端，在裙部销孔的下方分别各具有小槽。
本实用新型的上述结构由附图进一步说明。
附图为本实用新型的结构剖面示意图。
参见附图，图中的新型摩托车活塞包括头部、裙部3、裙部的销孔4；其特征在于：头部具有凹弧形顶端1，在裙部销孔4的下方分别各具有小槽2。
在上述结构中，活塞在轴向上的长度为42mm±0.5mm。
本实用新型虽然减小缸体内的压缩比，但由于增大了燃烧室的空间而能使燃烧完全充分，并能使活塞裙部和缸套的内导向好、配合更恰当；由于轴向上减小了活塞的长度，使原来的44mm±0.5mm变为42mm±0.5mm，使活塞的重量减轻、在缸体内的阻力减小；活塞裙部上增设的小孔能够使冷却和润滑效果更佳，并且对增加整个汽油机的功率提高有辅助的作用。

Claims (2)

1、一种新型摩托车活塞，包括头部、裙部(3)、裙部的销孔(4)；其特征在于：头部具有凹弧形顶端(1)，在裙部销孔(4)的下方分别各具有小槽(2)。
2、根据权利要求1所述的新型摩托车活塞，其特征在于：活塞在轴向上的长度为42mm±0.5mm。
