轻型货车离合器设计
摘要:
本设计的任务是对载重2吨的轻型货车离合器进行设计。考虑到膜片弹簧离合器是近年来在轿车和轻型货车上广泛应用的一种离合器,并且从提高离合器工作性能的角度出发,传统的推式膜片弹簧离合器结构正在逐步地向拉式膜片弹簧离合器结构发展,本设计主要针对拉式膜片弹簧离合器进行设计。
根据车辆使用条件和车辆参数,并且按照离合器系统的设计步骤和要求,本设计主要进行了以下工作:(1)离合器结构方案的确定,包括对从动盘数、压紧弹簧型式、扭转减震器、操纵机构等的选择;(2)离合器相关设计参数的确定及优化,包括后备系数、摩擦片尺寸、单位压力等;(3)膜片弹簧基本参数的确定及强度校核;(4)离合器主要零部件的结构设计,包括从动盘总成、离合器盖总成、分离装置等;(5)离合器踏板行程及踏板力的计算。本设计的创新点是在从动盘总成两侧增加了挡油板。挡油板可以有效防止润滑油溅入摩擦面之间,从而保证了转矩传递的可靠性和摩擦片的使用寿命。

Title The clutch design of light truck
Abstract
The task of this design is about the clutch design of light truck to load 2 tons. Taking into account that the diaphragm spring clutch is widely used in cars and light trucks in recent years, and from the perspective of improving performance of clutch work, the clutch structure is gradually developing from the traditional push-type diaphragm spring to the pull-type diaphragm spring, this design is mainly for pull-type diaphragm spring clutch.
According to the using conditions and vehicle parameters, plying with the procedures and requirements of clutch system design, the design is mainly for the following work: (1) Determine the program of the clutch structure, including the number of the driven plate、 type pression springs、 torsion dampers 、control mechanism, etc.; (2) Clutch relevant design parameters, including the reserve coefficientβ, size of friction plate, unit pressure p0; (3) Determine the basic parameters of diaphragm spring and check its strength; (4) The structural design of main parts of the clutch, including the driven disc assembly, clutch cover assembly, separation devices, etc.; (5) Pedal travel and pedal force calculations. The innovation of this design is the increase of the oil block board in the driven disc assembly on both sides. It can effectively prevent the spilled oil from e
