Abstract

A change gear transmission of the group design, especially for vehicles for agriculture and construction with a group transmission following a velocity control transmission the output shaft of which is arranged parallel to a main shaft. This main shaft is provided with gears connected to the main shaft for rotation therewith. The main shaft is driven through the intervention of a counter shaft of the velocity control transmission, which counter shaft is parallel to the main shaft. The counter shaft is through an input transmission continuously frictionally connected to the input shaft which latter is adapted by a clutch element in a direct velocity stage to be coupled to said main shaft. All gears of the main shaft mesh directly or indirectly with gears freely rotatable on said counter shaft and output shaft respectively. Each pair of these freely rotatable gears have associated therewith a common double control member which is axially displaceable on and connected to the output shaft and counter shaft respectively. One of the gears connected to the main shaft for rotation therewith meshes with a reversing transmission which latter includes a gear that meshes with one of the gears …
