Abstract
A gear system having a plurality of discrete gear ratios includes a retarder connected to a gear component intermediate between an input shaft and an output shaft. The gear component connected to the retarder is coupled to the output shaft with the same relative gear ratio greater than 1 in at least two adjacent ones of the discrete gear ratios of the gear system. The use of a relative gear ratio greater than 1 permits the use of a physically smaller retarder. The use of the same relative gear ratio between the retarder and the output shaft in at least two adjacent gear ratios of the gear system avoid jolts during shifting with the retarder engaged.
