一种电控硅油风扇离合器
本技术涉及汽车发动机冷却系统领域,具体涉及一种电控硅油风扇离合器。
技术介绍
随着国家经济的发展,对汽车节能,环境保护的要求越来越高,汽车工作的大部分时间都不需要风扇冷却,所以汽车的风扇自动离合技术是汽车节能的关键性技术。电控硅油风扇离合器作为汽车发动机冷却系统核心部件,其实现的功效对发动机的性能有着重要的影响。现有的部份电控硅油风扇离合器,其壳体与前盖之间为压接成形一体式结构,此结构对于总成装配及后期维护不利,一旦电控硅油风扇离合器内部出现问题只能以报废换新的形式来解决问题,是极大的浪费。市场现有电控硅油风扇离合器的原材料均由纯铁材料制作加工,从长期使用过程的角度看,纯铁材料的主动轴含碳量过低会导致了主动轴硬度与耐磨性上都有所欠缺。现有电控硅油风扇离合器内部的进油通路只有一条,容易造成硅油进入工作腔时流量不足,导致离合器的响应速度慢,转速滑差大。现有电控硅油风扇离合器的计数环都是由单独零件与壳体组装而成,其二者之间的间隙会引发离合器的渗油,降低电控硅油离合器的整体使用效果与使用寿命;现有电控硅油风扇离合器的散热是通过散热片将热能传递到大气当中。散热片的结构、数量、厚度等均影响电控硅油离合器的散热能力,散热片均采用以圆心向外按直线渐开线的形态均匀分布在离合器盖体表面,这种结构并没有完全利用电控硅油风扇离合器表面的空间,散热面积还有可提升的空间,同时其表面空气流通性存在着不足。
