Cable Shift System for Manual Transmissions 拉索式手动换档操纵系统一般性要求1 Introduction 1 介绍1.1 Scope. This specification outlines the technical specifications required for the cable shift system of manual transmissions. This specification applies to the assembly, specially to the shift lever knobs, to the mechanism, to the shift and select cables and to the shift lever boot (where applicable). 1.1范围本技术规范概要性的描述了拉索式手动换档操纵系统的要求包括操纵系统总成，尤其是换档手柄，操纵机构，换档换位拉索以及防尘罩（如果使用）Stipulation of the functional and durability require-ments placed on gearshift mechanisms is necessary in order to ensure the quality and service lifetime of the parts supplied. The requirements contained in this specification reflect those minimum values which are necessary in order to be able to carry out regular evaluation of conformity with design engineering targets. These requirements are to be looked upon as being an addition to validation tests, dimensional inspectionand ，and in process quality checks.为了确保质量和寿命，规定的功能和耐久性的要求是必要的。

为了达到工程设计目标，以便定期检查各项产品设计的要求，设置各项最小值是必要的这些要求作为除了验证测试，空间尺寸检查外，还应当进行过程质量控制 In the context of technological progress changes to the cable shift system design are both inevitable and desirable, this document is not intended to limit the supplier’s creativity. 操纵系统是不断完善的过程，本规范不应限制供应商的在零部件方面的创新1.2 Mission / Theme. The cable shift system is the driver interface to the manual transmission and pro-vides the ability to select the desired gear position. The cable shift system is controlled by the driver mov-ing the shift lever knob to the desired gear. 1.2主题换档操纵系统是驾驶员的一个重要人际界面，为驾驶员提高选择到正确到位的装置，通过驾驶员运动手柄球头来达到控制档位的目的。

The supplier of the cable shift system shall be a full service supplier with development, design and test capabilities. The supplier shall have testing facilities capable of performing and docu-menting all tests and validation requirements defined in this specification. The supplier shall validate the cable shift system according to section 5, and provide engineering support for the development, integration and application. The supplier shall have facilities to design, perform engineering analysis and maintain a drawing database. The drawings of the cable shift system shall be documented using the Unigraphics format. 3.1对供应商的基本要求供应商应具有开发、设计、试验一体的能力，具有能够测试本规范要求的一切要求的能力。

具有能够满足本要求第5 章的要求，能够为公司开发、集成、应用提供支撑应具有设计、工程分析、基本的制图设备制图要求用CATIA软件3.2 Interfaces. 3.2接口a Part interfaces between shifter, cables (including grommet to vehicle), cable abutments and cable end fittings shall be designed to fit together per design specification. a 换档机构、拉索（包括与车身之间的连接）、拉索之间的接口、拉索接头的接口设计都应该在满足每一个技术要求的前提下进行一体化设计bPart interfaces between shift lever knob, shift lever boot/cover, and gear lever itself shall be of appro-priate design. B 换档手柄、防尘罩（防尘盖）和换档机构本身之间的接口应该适当考虑c Shifter shall meet to floor pan specification shown in Appendix 1 and 2.C 换档机构应该满足地板安装的要求（按照附录 1 和 2）d Interfaces between shift lever boot/cover, shifter and centre console shall be tailored to fit together per design specification. d 换档防尘罩（防尘盖）、换档机构与换档控制箱之间的接口配合应该严格考虑3.3 Installation Space. The installation space is de-fined in Appendix 2. The shifter shall be fully con-tained within this envelope with exception to the shift shaft which will extend upward out of the space.3.3 安装空间要求安装空间按照附录 2 的要求。

换档机构应该进行包络检查，手柄球的运动范围很有可能会超出安装底座的范围3.4 Weight. 3.4重量1 Shifter assembly: 85 % (routing 90� with radius of 150 mm at room temperature with a force of 300 N). 拉索的效率应> 85 %（室温下， 300N的拉力，用150mm的曲率半径弯成90 度进行测量）The free play in the cable shall be 80 % b select plane > 70 % 5.2.4 Friction. Mount the shifter complete with ca-bles in a test bench in the reference installation posi-tion. The load required to operate in the shift plane and the select plane is to be measured with loose ca-bles at the LAP. (Before measurement 10 movements in all shift and select planes are to be performed.) Requirement: aShift 80％b 选择面> 70％5.2.4 摩擦。
