A vehicle comprises a chassis, a pair of driving wheels, a pair of idle wheels, at least one steering group, and a differential. The steering group is capable of positioning one of the pairs of wheels in a steering geometry where an axis of each of the wheels of the pair of wheels capable of being positioned by the steering group intersects with the remaining axis within a ground-support quadrilateral formed by the pairs of wheels. The differential comprises an outer case, an inner case, a selective engagement, a selective blocking means, and a selective direct gearing means. When the inner case is coupled to the outer case a first half-shaft and a second half-shaft are driven similarly and when the inner case is coupled to the chassis and one of the half-shafts is drivingly engaged with a crown gear the first half-shaft and the second half-shaft are driven opposingly.

Vehicle

A transmission has a directional mechanism, a planetary gear mechanism, a stepped transmission and a continuously variable ratio device. The directional mechanism has at least one direction clutch. The planetary gear mechanism is connected to the direction mechanism and has at first planetary gear set and a second planetary gear set. The stepped transmission is connected to the planetary gear mechanism and has at least one speed clutch. The planetary gear mechanism is connected to a hydrostatic motor of the continuously variable ratio device. The motor is connected to a variable displacement pump of the continuously variable ratio device.

Power split transmission

An engine half-trolley ( ) of simplified structure for industrial vehicles set at the side of a vehicle chassis and comprising a casing ( ) from which there comes out at least one wheel hub ( ) for a respective wheel ( ), an input shaft ( ) to said half-trolley ( ) being connected to a differential ( ) of the vehicle, in the said half-trolley, between the input shaft ( ) and the wheel hub ( ), there being provided, in succession, two bevel-gear pairs ( ) housed in an arm ( ) forming part of the casing ( ), in which at least one bottom area of the arm ( ), for attachment to the wheel hub ( ), has ample bevels ( ).

Engine half-trolley for industrial vehicles

A device for measurement and control of the conditions of stability of a vehicle, in particular an industrial vehicle, comprising at least one load cell ( ), which is integrated inside the lower pin of each articulated joint or steering &ldquo;pivot&rdquo; ( ) of each steering axle ( ) of the vehicle, at the level of the wheel hubs ( ), so that a structural component of the front and rear steering axle of a four wheel vehicle is a measurement instrument; an electronic control instrument ( ), by means of appropriate control software, processes signals (P -P ), appropriately amplified, transmitted by each load cell ( ), so as to calculate the stability of the vehicle in real time and, furthermore, provide a command to disable certain vehicle functions, in the event that the stability values are beyond a certain pre-established safety range.

A system for sensing the spatial position of suspended axles in industrial vehicles includes two angular sensors ( ) fitted on opposite pins ( ), each of which is provided with a relative spherical coupling ( ) for a panhard bar ( ) interposed between an axle ( ) and the chassis ( ) of the industrial vehicle. Each of the sensors ( ) interposed between the axle ( ) and the chassis ( ) of the industrial vehicle is operated by elastic laminas ( ) and each sensor has a drive pin rotated by a corresponding rotating hub ( ), the angular sensors ( ) detecting the spatial oscillations of the panhard bar ( ) in relation to the axle ( ) and the chassis ( ) of the industrial vehicle. There are two elastic laminas ( ) for each angular sensor ( ) and these are fitted parallel to a lateral surface of the panhard bar ( ), partially overlapping one another and fixed at one end to one of the angular sensors ( ) and at the other end to the surface of the panhard bar ( ).

Axle position sensor system for industrial vehicles

A suspended axle ( ) of the articulated-connection type for industrial vehicles comprises a central casing ( ) from which two arms ( ) extend, each of which carries, at one of its ends, a support ( ) for a wheel, the axle ( ) being connected to the chassis ( ) of the industrial vehicle by means of first bars set transversely and second bars set longitudinally with respect to the vehicle, where the transverse bars comprise a Panhard rod ( ). In addition, interposed between the axle ( ) and the chassis ( ) are hydraulic elements ( ). The longitudinal bars each consist of a single strut ( ) having one end connected to the central casing ( ) and one, opposite, end connected to the chassis ( ) with interposition of a ball-and-socket joint ( ).

A compact braking assembly in an axle for an industrial vehicle comprising, within an internal body ( ) which extends in an arm ( ), supported in a rotatable manner (in ) a casing ( ) of a differential ( ) provided with a first set of disks ( ), with a second set of disks ( ) also positioned between the casing ( ) and said arm ( ) of the axle, with a piston ( ) acting on the first set of disks ( ), operated by a fluid fed from a respective duct ( ), which axially moves a ring ( ), distributor of an operating force of the piston ( ), in which the piston ( ) successively positions the first set of disks ( ) in a pack acting as a differential lock, subsequently positioning the second set of disks ( ) in a pack acting as a service brake thanks to the presence of a pre-established preloaded elastic element ( ).

Compact braking assembly in an axle for an industrial vehicle

A device to control the dynamic stability of an industrial vehicle, where the chassis of the aforesaid vehicle is fitted with a pair of axles ( &Prime;), extending from each of which are booms ( &prime;), fitted to the ends of which are articulated steering pivots ( &prime;) of the wheels of the aforesaid vehicle and where interposed between the axle ( ) and the frame ( ) of the aforesaid industrial vehicle are hydraulic cylinders ( &prime;), said control device providing that each hydraulic cylinder ( &prime;) is associated with pressure transducers capable of indicating the loads weighing instantaneously on each wheel hub, thus permitting, by means of appropriate data processing, detection of the condition of stability of the vehicle, said pressure transducers ( ) being associated with hydraulic cylinders ( &prime;) so as to operate in real time to provide the initial data to process the conditions of stability on which to base the control of vehicle stability.
