Секвентальная коробка передач Tractive RD90 RWD
Секвентальная коробка передач для заднеприводных автомобилей Tractive RD90 это:
Применение
Секвентальная коробка передач RD90 используется в заднеприводных автомобилях. Различные версии коробок передач RD90 подходят к очень разным автомобили, от MKII Escort с крутящим моментом 220 нМ до автомобилей с двигателями V8 с крутящим моментом 900 нМ. Сейчас и в большинство переднеприводных автомобилей, выигрывающих в локальных чемпионатах, проводимых в Швеции, устанавливают коробку передач RD90.

| Вес: | 30 кг | 35 кг |
| Конструкция корпуса: | Симметричный дизайн обеспечивает температурную стабильность и равномерное отклонение корпуса во время высоких нагрузок. Естественный и благоприятный путь нагрузки предназначен в whole layout. Все детали изготовлены из пресованного алюминия авиационного качества, отливки не используются. |
|
| Вал сцепления: | A separate clutch shaft drives the input shaft via a splined coupling. Different lengths and spline configurations are possible. The standard Ford 1”-23 spline is preferred for a shorter lead time, while we certainly can make any type of spline to any type of clutch. | |
| Clutch release mechanism: | Not integrated with the gearbox. Usually fitted in the standard bellhousing. | |
| Clutch rings (dogrings): | Tractive standard with 90 mm O.D. with radiused corners for long lifge and good durability. | |
| Gear selection mechanism: | Sequential shift mechanism extensivley developed by Tractive from Honda MX-bike origins. | |
| Cockpit Gear Lever: | Tractive sequential shift gear lever with return springs. | |
| Connection between gear Lever and gearbox: | Through 8 mm stanless steel rods, either direct or over a bell crank on the prop-shaft tunnel. | |
| Reverse gear engagement: | With clutch ring shared with 1:st gear. Note! No sliding gears, no chips or swarf in the gearbox. | |
| Reverse gear release mechanism: | A separate lever on the gear lever must be operated to release engagement of reverse gear. | |
| Gear wheel width: | 17 mm for all gears. | |
| Ratios: | See Ratio charts | |
| Drop Gears: | The RD905 and RD906 gearbox have a drop gear arrangement to compensate for various rear axle ratios, or to fine tune the top speed and acceleration characteristics. Two gear situated behind a cover at the rear of the gearbox are easily replaced to alter the overall ratio of the gearbox. 13 different drop gears are currently in production. | |
| Gear selection mechanism: | Sequential shift mechanism extensivley developed by Tractive from Honda MX-bike origins. | |
| Bearings: | Standard type SKF cylindrical roller bearings for input and output shafts. Ball bearings for selector drums. | |
| Bearings in clutch gears: | INA cage type needle roller bearings. | |
| Lubrication | Wet sump. A GL5 spec. transmission oil is recommended. | |
| Seals: | Nitril as standard or Vition alternatively PTFE-lipped low friction seals on request. | |
| Shot peening: | All gears and dogrings are shot peened unless otherwise specified by the customer. The cost for shotpeening is included in the quoted price. | |
| Surface treatment of casing: | All parts making up the casing are anodized in black colour. | |
“I had a Motorsport business and ran Opels Fords and Toyotas, but the Tractive Transmission is the most impressive piece of engineering I have encountered”.
