摘要:
A method for arranging an accumulating device in proximity of a floor of a vehicle forming a bottom wall of a passenger compartment of the vehicle itself; the accumulating device has a heating base wall which is free from heat insulation, and a non-heating base wall which is parallel and opposite to the heating base wall and is provided with a heat-insulating material layer; and the method provides for the steps of arranging the accumulating device in a seating obtained in proximity of the floor; and implementing the accumulating device with a symmetry allowing the reversal of the accumulating device itself within the seating obtained in proximity of the floor in such a way that the heating base wall may be equally either facing upwards and then towards the passenger compartment or facing downwards and then towards the external environment.

A connectable four-wheel drive vehicle includes an engine having a gear shaft; two main drive wheels connected permanently to the drive shaft by interposition of a gearbox having a first clutch; and two secondary drive wheels selectively connectable to the drive shaft by a connectable drive system. The connectable drive system includes a second clutch which, on one side, is connected with a fixed velocity ratio to the drive shaft upstream from the gearbox, and on another side, is connected with a fixed velocity ratio to the secondary drive wheels.

摘要:
A motor vehicle with insertable four-wheel drive, including an engine having a crankshaft, a pair of main driving wheels constantly connected to the crankshaft by interposition of a gearbox provided with a first clutch, and a pair of secondary driving wheels, which may be connected to the crankshaft by an insertable transmission system. The insertable transmission system presents a second clutch, which is connected on one end with a fixed transmission ratio to the crankshaft upstream of the gearbox and on the other end with a fixed transmission ratio to the secondary driving wheels. A percentage of motive torque to be transmitted to the secondary driving wheels by the second clutch is determined according to dynamic parameters of the motor vehicle detected by respective sensors.
