Abstract:
The invention is a transmission unit with orthogonal axes for vehicles, comprising: a drive shaft (1) connected to a gearmotor unit with differential, comprising: a crown gear (2) that meshes with the drive shaft (1), said crown gear housing, in two diametrically opposed cavities (22, 23), one pair of planetary gear wheels (41, 42) having their axis lying on an ideal plane containing said crown gear; two sun gear wheels (35, 55) meshing with said planetary gear wheels (41, 42), each connected to an axle shaft (3, 5) belonging to a driven wheel. The crown gear is housed, rotatingly free, in one axle shaft (3) only.
Abstract:
Connection coupling (1 ) for the shaft (A) of a motor (M) and the input shaft (I) of a reduction gear (R). It is constituted by a single shaped body (2) suited to be housed in a seat (5) made in the shaft (A) of the motor (M) and in which it is possible to identify a shaped hole (3) suited to house a tang (4) belonging to the input shaft (I) of the reduction gear (R). The shaped body (2) inside the seat (5) and the tang (4) inside the shaped hole (3) mutually cooperate through one or more counteracting surfaces (8, 9, 10, 11 ) for the transmission of the torque from the motor (M) to the reduction gear (R).
Abstract:
Cleaning machine (1) of the type comprising: a chassis (2) complete with wheels (3, 4, 5); driving means (6) including a geared motor (21) associated with one of the wheels (3, 4, 5); steering means (7) comprising a geared motor (30) for steering one of the wheels (3, 4, 5) and a central processing unit (9) governing the steering action; means (18) for monitoring the angular position of the wheel (5) associated with the steering motor (30); means (17) for monitoring the travel speed of the machine (1); control means (8) governing the driving means (6) and the steering means (7). The central processing unit (9) consists of a microcontroller (10) with a programmable memory element (11) containing one or more programmed functions suitable for correlating the electrical values coming from the control means (8) and from the means (17) and (18) for monitoring the speed of the machine and the angular position of the wheel, in order to adjust the power supply to the steering geared motor (30).
