A portal gear box assembly for an all-terrain vehicle includes: a portal gear box housing a set of gears and linking an axle to an output shaft; a lubricating oil contained in the gear box; and a fluid circulation loop that circulates a cooling fluid to a cooling location outside the gear box. The cooling fluid may be a lubricating oil. The fluid circulation loop may include a pump and/or a filter. The cooling location may pass the fluid through a structure such as a radiator or other cooler. The circulation loop and/or any radiator/cooler, filter, or pump contained therein, may serve a single portal gear box, or may serve two or more portal gear box assemblies.

A transmission for an agricultural or heavy load vehicle is provided, and includes a central drive shaft, at least one planetary gearset comprising a planet carrier, at least one output drive element, and one brake device. The drive shaft is connected to the output drive element via the planetary gearset. The brake device is located between the planet carrier and the output drive element in the form of a ring gear, such that the output drive element can be coupled to the planet carrier via the brake device.

A powershift transmission for an agricultural machine includes a transmission housing, an input shaft and an output shaft unit. The input shaft and the output shaft unit extend at least at a distance within the transmission housing. The transmission also includes an auxiliary shaft arranged within the transmission housing and offset between the input shaft and the output shaft unit. The input shaft and the auxiliary shaft are connected to one another via a front-mounted range unit, and the auxiliary shaft and the output shaft unit are connected to one another via a rear-mounted range unit. Each range unit includes at least two individual gear wheel pairs which are coupled or decoupled. The output shaft unit includes a main output shaft and an auxiliary output shaft coupled to one another via a reduction gear unit.

A liquid-cooled integrative power system for electric forklift includes an integrated transmission gearbox, an integrated motor controller, a drive motor, an oil pump motor, an oil pump and a vehicle controller. The integrated transmission gearbox includes a drive motor transmission mechanism and an oil pump motor transmission mechanism. The integrated motor controller includes a drive motor control unit and an oil pump motor control unit. The integrated transmission gearbox, the integrated motor controller, the drive motor, the oil pump motor, the oil pump and the vehicle controller are completely integrated and mounted to form the liquid-cooled integrative power system for electric forklift.

The invention relates to a gearbox (1) comprising: a gearbox body (1A) defining an enclosure (1B), an input shaft (2), an output shaft (3) and a mechanism (4) for transmitting the movement of the input shaft (2) to the output shaft (3), said mechanism (4) for transmitting movement comprising at least one clutch (5) and a clutch (5) control device, the clutch (5) comprising a driving element (6) and a driven element (7) mounted rotatably secured to the output shaft (3) and having its axial movement limited in at least one direction along the output shaft (3), and the clutch (5) control device comprising a member for controlling the movement of the driving element (6) and the driven element (7) towards one another to allow the clutch (5) to pass from the declutched position to the clutched position. The control member is formed by the gearbox body (1A) mounted to slide along the output shaft (3).

A drive assembly for a work vehicle includes a drive housing, a drive shaft rotatable about a drive axis, an inner hub rotationally fixed to the drive shaft, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes a clutch arrangement having a clutch ring configured to selectively engage the planetary gear set. The clutch arrangement further includes a guide assembly mounted on the clutch ring and configured to selectively interact with the planetary gear set to effect disengagement of the clutch ring from the planetary gear set. A clutch actuation assembly is configured to effect movement of the clutch arrangement along the drive axis to engage the planetary gear set, and a guide actuation assembly is configured to operate the guide assembly to interact with the planetary gear set.

An apparatus and methods are provided for a rear portal trailing arm assembly for a vehicle rear suspension. The trailing arm assembly comprises a CV joint hub for coupling with a transaxle and a wheel hub for coupling with a rear wheel. A gear transfer case extends rearward from the CV joint hub to an axle case and functions similarly to a rear trailing arm. Forward mounts facilitate coupling the gear transfer case to the chassis such that the trailing arm assembly pivots vertically with respect to the chassis. A rearward mount facilitates coupling a strut with the gear transfer case to control the vertical motion of the rear wheel. Multiple gear assemblies are meshed within the gear transfer case. An axle is coupled with the meshed gear assemblies and housed within the axle case, such that torque applied to the CV joint hub is communicated to the wheel hub.

A method is provided for configuring different numbers of gearshift variants in a stepped powershift transmission for an agricultural working machine. The method includes providing a transmission unit, a front-mounted range unit, a gear reduction unit, a rear-mounted range unit, a housing, a drive shaft, a lay shaft, an output shaft, and a hydraulic control arrangement. The same transmission unit is used for all the numbers of gearshift variants while an identical spatial orientation of the shafts is maintained for all the numbers of gearshift variants. The method further includes adapting exclusively the gearshift variants by varying the front-mounted range unit or the rear-mounted range unit.

A lubrication arrangement includes at least one housing, at least one shaft, at least one bearing system configured to hold the at least one shaft in the at least one housing and to permit the at least one shaft to rotate, lubricant distributed in the at least one housing with the rotation of the at least one shaft, and a lubricant deflector provided in a stationary manner relative to the at least one housing above the at least one shaft. The lubricant strikes against the lubricant deflector and, by action of gravity, the lubricant is conducted to the at least one bearing system of the at least one shaft so that the at least one bearing system is supplied with the lubricant.

A utility vehicle including an engine; an exhaust pipe through which exhaust gas is discharged from the engine, the exhaust pipe being connected to the engine; and an air guide that guides outside air toward the exhaust pipe.
