1、 1 膜片式离合器的设计膜片式离合器的设计 摘要摘要:离合器装在发动机与变速器之间,汽车从启动到行驶的整个过程中,经 常需要使用离合器。它的作用是使发动机与变速器之间能逐渐接合,从而保证汽 车平稳起步;暂时切断发动机与变速器之间的联系,以便于换档和减少换档时的 冲击;当汽车紧急制动时能起分离作用,防止变速器等传动系统过载,起到一定 的保护作用。离合器类似开关,接合或断离动力传递作用,因此,任何形式的汽 车都有离合装置,只是形式不同而已。现在,电子技术也进入了离合器系统。一 种由控制单元(ECU)控制的离合器已经应用在多款的轿跑车上。 关键词关键词:从动盘总成 传动系 膜片弹簧 非线性弹性特性
2、Diaphragm type couplings design Abstract: The coupling installs between the engine and the transmission gearbox, the automobile from the start to the travel entire process, needs to use the coupling frequently. Its function is causes between the engine and the transmission gearbox can join gradually
3、, thus guaranteed that the automobile starts steadily; Shuts off between the engine and transmission gearboxs relation temporarily, is advantageous shifts gears and reduces shifts gears the time impact; When automobile emergency brake can play the separation role, prevents transmission systems and s
4、o on transmission gearbox to overload, plays certain protective function. The coupling similar switch, the joint or breaks to the power transmission function, therefore, any forms automobile has the engaging and disengaging gear, is only the form is different. Now, the electronic technology also ent
5、ered the coupling system. One kind the coupling which (ECU) controlled by the control unit already applied on many patterns sedan race car.
