Problems solved by technology

[0006] Obviously, a considerable disadvantage of this approach is the fact that even in the event of a failure of a single component, the entire transmission still needs to be removed
[0013] Furthermore, removing the entire transmission requires suitable support equipment, which is difficult to transport

Abstract

Transmission group (10) for vehicles (11) comprising an engine (12) provided with at least one engaging device (17), arranged between transmission gears (15, 16) and mobile between a first rest position, wherein the transmission gears (15, 16) are mutually integral and both in mesh with a transmission shaft (14), and a second working position wherein the first gear (15) is in mesh with the transmission shaft (14) and the second gear (16) is unconstrained both with respect to the transmission shaft (14) and with respect to the gear (15), provided for being means for actuating of the engaging device (17), wherein the engine (12), an output gear (18) and an output shaft (13) are integrated in a first module fixed to the vehicle (11) and that the transmission shaft (14), the transmission gears (15, 16), the engaging device (17); and the actuating means thereof are integrated in a second module (31) independent and demountable with respect to the first module (30).

Description

technical field [0001] The present invention relates to an improved transmission group for a vehicle and to a vehicle equipped with such a transmission group. Background technique [0002] Vehicle transmissions of the type currently known comprise an engine for generating motion and an output shaft for transmitting the motion to a unit, for example to a wheel. [0003] In general, known transmission groups further comprise a propeller shaft meshing with the engine, a transfer gear associated with the propeller shaft, and an output gear associated with the output shaft, said output gear meshing with at least one transfer gear. [0004] In the case of several gears in the transmission gear, or in the case of several direct drive torque motors in the vehicle, the transmission gears are further respectively equipped with synchronizers and / or clutches arranged on the transmission gear and the corresponding actuator. [0005] Usually, all the above-mentioned elements are assembl...
