VDA 260 3 General Requirements 3一般要求3.1 Requirements to the Supplier of the Cable Shift System. The supplier of the cable shift system shall be a full service supplier with development, design and

2、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, in

3、tegration 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、

4、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。

5、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,

6、 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 wil

7、l 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 0.6 mm

8、（routing 90 with radius of 150 mm at room temperature with a force of 10 N）. 拉索的无效行程应该小于 0.6 mm（室温下， 10 N的拉力，用150mm的曲率半径弯成90度进行测量） The cable cores shall be protected against environ-mental effects at transmission side. 变速器端的拉索接头应该具有防污染保护装置。 The cable radius shall be 150 mm minimum. 拉索布置应该不小于150mm的曲率

9、半径 The cables shall be adjustable at the shifter side （range of adjustment: 6 mm） and the adjuster shall be activated from the top through the console opening. 拉索的调节机构应该位于换档操纵机构一端（调节行程： 6 mm），同时在将防尘罩打开的情况就能调节。 The Pull-off load of select cable end fittings on transmission side shall be 1000 N minimu

10、m. The force is applied perpendicular to pin ball. 在变速器端的换位拉索接头与销子的拔出力最小为1000N。拔出力方向为拉索销的竖直方向。 The Pull-off load of shift cable end fittings on trans-mission side shall be 1800 N minimum. The force is applied perpendicular to pin ball. 在变速器端的换档拉索接头与销子的拔出力最小为1800N，拔出力方向为拉索销的竖直方向。 The abutments of the

11、 cables shall have a top load snap-in design at transmission and shift lever side, on the transmission side they shall have additional rotary symmetry. The Snap-in insertion of the abutment of the cables shall be 50 N maximum. The pull-off load shall be at shifter side 150 N minimum and on transmiss

12、ion side 400 N minimum. Easy removal with out tool shall be possible on shifter and transmission side.所有的拉索套管帽装配力最大为50N，换档器端拔出力最小为150N，变速器端最小为400N。同时在不使用工具的情况下能够轻松从支架上拆除。The cable end fittings shall be attach to ball pins on transmission side. The ball pins shall have a diameterof 10 mm h9拉索接头能很好装配到变速器的销子上，销子的直径应该为10 mm h9。The “snap-in” insertion of the cable end fittings to transmission pin ball shall be （75 20） N. The removalshall be 500 N minimum axial
