Abstract
In a shift mechanism of a gearbox, wobbling movements of an idle wheel rotatably mounted on a transmission shaft are suppressed by there being provided in an axial coupling toothing involved in the coupling of the idle wheel to the transmission shaft a tooth pair which comprises two diametrically opposite coupling teeth with respectively leading pitch deviation.
Claims14
Shift mechanism of a gearbox, comprising:
- an idle wheel mounted rotatably and axially immovable on a transmission shaft, having a coupling ring with an outer axial coupling toothing arranged coaxially and immovably,
- a shift sleeve carrier arranged immovably on the transmission shaft and having on the outer circumference an outer axial coupling toothing, and
- an annular shift sliding sleeve, having on the inner circumference an inner axial coupling toothing corresponding to said outer coupling toothings, wherein at least one of either the outer coupling toothings has a tooth pair corresponding to two diametrically opposite coupling teeth having a pitch which deviates substantially from the pitch of other teeth.
