Patent ID: 7946190

Claim:
A shift rocker arrangement ( 2 ), for a shift transmission, comprising a shift rocker ( 4 ) having a bracket with two-arms ( 14 , 16 ) that extend around a transmission element to be shifted, the bracket being pivotally supported within a transmission housing ( 42 ) by pivot bearings to pivot about a pivot axis ( 6 ) which is located essentially in a first plane of the bracket that is defined by the bracket arms ( 14 , 16 ) of the bracket, the pivot bearings comprise bracket bearing elements ( 24 ), that are formed on the bracket arms ( 14 , 16 ), and complementary bearing elements, that are supported on inner walls of the transmission housing, each of the bracket bearing elements ( 24 ) includes pivot-pin bearing surfaces ( 26 , 28 ) that contact bearing shells ( 38 , 40 ) that form the complementary bearing elements that are supported on the inner walls of the transmission housing ( 42 ), in a second plane defined by the bracket arms that is perpendicular to the pivot axis, the bracket bearing elements ( 24 ) have two circular-section wider areas ( 30 , 32 ) that comprise the bearing surfaces ( 26 , 28 ), and the bearing shells ( 38 , 40 ) are complementary to and partially surround and encompass the bearing surfaces ( 26 , 28 ); and the bracket bearing elements ( 24 ) are formed on the two arms ( 14 , 16 ) such that the two arms ( 14 , 16 ) pass between the bearing shells ( 38 , 40 ), the bearing shells are respectively formed on a bearing bar ( 36 , 37 ), one end of the bearing bar is mounted in a main housing portion ( 46 ) and an opposite end of the bearing bar is mounted in a housing cover ( 48 ), the two arms ( 14 , 16 ) are fixed to each other such that the shift rocker ( 4 ) has a U-shape, and the bearing bars ( 36 , 37 ) extend from the main housing portion ( 46 ) to the housing cover ( 48 ) on an inside of the U-shaped shift rocker ( 4 ) between the two arms ( 14 , 16 ).
