丰田卡罗拉离合器的总体设计
摘要
汽车与人们的生活息息相关,它是人们现实生活中必不可少的出行工具。在汽车传动过程中,离合器性能的好坏直接影响着汽车的使用性能。离合器的主要功用是切断和实现对发动机的动力传动,保证汽车起步时将发动机与传动系平顺结合,确保汽车平稳起步。
汽车离合器有摩擦式、液力式和电磁式三种类型,摩擦式离合器的使用最为广泛。本论文根据离合器的设计原理和车辆的使用条件以及车辆参数,按照离合器系统的设计步骤和弹簧要求,主要进行了以下工作:选择相关设计参数,离合器容量参数,离合器后备系数β的确定,单位压力p的确定,摩擦片外径D确定。并进行了总成设计,主要为减振从动盘设计,压盘设计,离合器盖的设计和圆柱螺旋弹黄的设计。

Abstract
The car is closely linked with people's life, it is essential to people in real life, travel tools. In the car in the process of transmission, clutch performance directly affects the performance of the vehicle. The main function of the clutch is cut off and the realization of power transmission to the engine, to ensure the car started the engine and transmission system with the smooth, ensure a smooth start car.
Friction type, hydraulic and ic three types of automobile clutch, the use of the friction clutch is most widely. In this paper, according to the design principle and a clutch of a vehicle using conditions and vehicle parameters, in accordance with the design steps and spring clutch system requirements, mainly for the following work: select the relevant design parameters, clutch size parameters, determine the clutch reserve coefficient, determines the unit pressure of P D determine the diameter, friction plate. And the assembly design, the main design for reducing vibration, driven pressure plate, clutch cover design and cylindrical spiral shells Huang design.
Key words:Clutch;Cylindrical Spiral Spring;Friction;Thedriven plate; Pressure plate
