Antriebsstrang mit Vorrichtung gegen Klappergeräusche

摘要

An improved vehicle transmission (10) which substantially reduces the noisy rattle normally produced by interengagement of the input shaft (12) and the input drive gear (14) of the transmission when the engine of the vehicle is operating at idle speed and the transmission is in neutral. The input shaft (12) and the input drive gear (14) are in constant driven relationship. In the inventive structure, the interengageable spline teeth (70 and 71) of the input shaft (12) and the input drive gear (14) of the transmission (10) are provided with a greater backlash (75) than is normally used. The intermittent firings of the engine (E) normally cause non-synchronous rotation of the input shaft (12) relative to the input drive gear (14) with attendant engagement of their respective spline teeth (70 and 71). The increased backlash (75) provides greater spacing between the interengaging teeth which substantially eliminates the engagement of the spline teeth and attendant rattle noise.
