Abstract

A gear mechanism for a full-track vehicle has a carrier-like housing (1) in which and on which are only fastened and positionally fixed in respect to each other prefabricated and examined subassemblies (2 to 11), while the functional--operative fluid and electric--connections between the subassemblies (2 to 11) result via flexible connections which compensate for deformations caused by heat and load and deviations caused by tolerance. The fastening of the subassemblies (3, 4, 5, 8) by bearing, centering and fastening elements (12) makes possible, if there is a good positional fixing, a great simplification. The functional connection of the subassemblies (2 to 11) also leads directly, together with the reduction of the coupling points, to a simplification of the gear housing (1) and to a reduction in the cost of machining and control.
