  • Patent number: 5495775
    Abstract: A stepped motor vehicle transmission comprises an input shaft, a first and a second intermediate shaft and an output shaft. The shafts are arranged parallel to each other, but only two each are arranged in a common plane. Toothed wheels are provided on the shafts meshing in pairs with each other. Gearshift sleeves are provided for drivingly connect one each loose toothed wheel of the pairs with the respective shaft on which they are journaled. The respective other toothed wheels of the pairs are designed as fixed wheels. The input shaft, the first intermediate shaft and the second intermediate shaft are each provided with a gearshift sleeve being displaceable in two gearshift directions each for engaging a total of five forward gears and one reverse gear. One supplemental fixed toothed wheel on the first intermediate shaft meshes with a loose toothed wheel on the input shaft. Further, one supplemental fixed toothed wheel on the second intermediate shaft meshes with a toothed wheel on the output shaft.

  • Patent number: 4817773
    Abstract: In synchronizing mechanisms for clutches having arranged between the clutch body (10) and the axially displaceable gear shift sleeve, each of which are provided with a toothing, a synchronizing ring (14) with teeth (33) having inclined check faces (35, 36) provided on their ends facing the gear shift sleeve, which check faces (35, 36) coact with matching check faces (37, 38) on the ends of the teeth (34) of the gear shift sleeve, it is provided for the purpose of reducing cold scratch that the check faces on the ends of the teeth (34) of the gear shift sleeve are designed asymmetrically in such a manner that the check faces (37) leading in the sense of rotation (28) have a greater axial extension than the check faces (38) trailing in the sense of rotation.
