A drive arrangement of a working machine to be driven at a variably adjustable speed includes a differential gear, a first drive unit coupled to a first element of the differential gear, a working machine coupled to a second element of the differential gear, and a second drive unit coupled to a third element of the differential gear. The speed of the second drive unit can be superimposed on a speed dependent on the speed of the first drive unit, whereby the first or second drive unit can be driven at a variably adjustable speed. The drive arrangement includes an auxiliary gear stage and a switching element interacting with the auxiliary gear stage, wherein, when the switching element is closed, the auxiliary gear stage is load-transmitting and the speeds of the first and second drive units are coupled as a function of at least one transmission ratio of the auxiliary gear stage, and when the switching element is open, the auxiliary gear stage is load-free and the speeds of the first and second drive units are decoupled.

[Technical problem] To provide a power transmission mechanism for a four-wheel drive vehicle in which a prime mover is disposed at a low position to lower the center of gravity of the vehicle while a driving path from a transmission to a front wheel differential mechanism is also shortened. [Solutions] In a power transmission mechanism for a four-wheel drive vehicle, the power of a prime mover is transmitted to a front wheel differential mechanism which is disposed in front of the prime mover, and to a rear wheel differential mechanism which is disposed behind a transmission, through the transmission which is disposed behind the prime mover. The transmission comprises a front and rear wheel drive shaft that extends along the longitudinal direction of the vehicle body. The transmission is arranged separately from the prime mover and a rear axle drive device. The rear end portion of the front and rear wheel drive shaft is connected to an input shaft of the rear wheel differential mechanism. The front end portion of the front and rear wheel drive shaft is connected to an input shaft of the front wheel differential mechanism via a front wheel power transmission shaft that extends along the longitudinal direction of the vehicle body and passes through the space beneath the prime mover. The front wheel differential mechanism, the prime mover, the transmission, and the rear wheel differential mechanism are arranged along the longitudinal direction of the vehicle body at the center of the vehicle width of the vehicle.

There is provided a gearbox apparatus in which the number of gears selectable by a user to drive a drive shaft is greater than the number of gears physically connected to the drive shaft of the gearbox. This apparatus can be controlled remotely by a wireless signal emitting or receiving electronic device, which includes a smart phone, desktop computer, a signal tower, and the like
