汽车变速器换档自锁装置的
设计与分析研究

摘要 ：本课题的研究，主要是分析单轨式和多轨式变速器操纵机构，对比两种不同结构的操纵机构分析其各自的结构特点，锁止装置的不同，适用场合也不径相同，最后通过对比分析提出自己的优化设想。
从分析单轨式和多轨式变速器操纵机构的机构特点着手，先对两种不同操纵机构所应用的变速器进行对比，分析两种变速器各自的优缺点及其使用场合。再对两种操纵机构进行分析，对比结构上有的不同之处。由于多轨式操纵机构有多根拨叉轴组成，单轨式操纵机构只有一根拨叉轴，那么这两种操纵机构的拨叉轴放置方式就存在差异。多轨式操纵机构每根拨叉轴上都装一个拨叉，而单轨式操纵机构所有的拨叉都是装在同一根拨叉轴上，单轨式操纵机构相对于多轨式操纵机构减少了拨叉轴的数量，改变了操纵机构的整体结构，使变速器操纵机构的结构更加紧凑，对拨叉的布置方式也作了极大的改变，那么对拨叉的结构设计也会造成一定的影响。
汽车在行驶中由于道路条件不好或是承载量过大等一些因素的影响，容易造成变速器的自行脱档。所以保证变速器在任何情况下都能准确、安全、可靠的工作是变速器设计的关键，那么对于操纵机构就得提出一定的要求，必须保证变速器不自行挂档和脱档，不能同时挂上两个档位，还有不能误挂倒档。所以就要求变速器操纵机构必须具有可靠的锁止装置。
无论多轨式还是单轨式的变速器操纵机构，它都有自锁装置、互锁装置和倒档锁装置。基于两种变速器操纵机构结构上的差异，其各大锁止装置的结构也是不尽相同的。但总的来说，变速器操纵机构锁止装置的作用就是为了使拨叉有个准确的定位，从而使变速器只能挂上一个档位和所挂档位不自行改变，保证了行车的安全性。

Abstract : The research of this topic, mainly is to analyze the single-selector rod type and multiple-selector rod type shifting device in transmission. contrast two kinds of dissimilarities structure and characteristics of each equipment. Analyze the difference of two kings of locking device. And they have different applied situation. Finally, we can put forward our improvements.
When analyze the characteristic of the selector mechanism of single-selector rod and multiple-selector rod transmission. Firstly, we can contrast two kinds of different transmission, analyze their merit and applied situation. And secondary analyze the structure of two different selector mechanism. The multiple-selector rod selector mechanism has multiple selector rods, but the single-selector rod type has only one. So there are much difference on structure.Each selector rod of multiple-selector rod transmission mounted a selector fork, but on the single-selector rod transmission, there has only one selector rod for many selector forks. Comparing with the multiple-selector rod transmission, the single-selector rod transmission decreasing the sum of selector rods, changing the structure of transmission and make it closely. The single-selector rod transmission changing the arrangement of the selector rod tremendously, so it can also affect the structure of selector fork.
Because of the rough road condition or the heavy load affecting, it easily drop out from the normal driving situation for the selector mechanism in transmission. Above all, it is the most important to assure transmission run accurately, safely and dependable under all circumstances on the design of transmission. So we have to put forward some request for the selector mechanism. We must assure that the selector mechanism doesn’t shift by no shift power (holding the gear in position).and prevent two gears being obtained at the same time, and the reverse gear being obtained at driving forward. So we require the selector mechanism with dependable lock equipment.
Both of the selector mechanism in multiple-selector rod transmission and single-selector rod transmission, they are all having self-locked, interlock and reverse-locked device. Because of tw..
