Abstract: A stepless speed variation transmission drive unit, in particular for industrial, agricultural or railway machinery, comprises at least a first input pinion (10), at least a first hydraulic motor (12) connected to said first input pinion (10), an output shaft (30), and at least a second hydraulic motor (22, 23). The first hydraulic motor (12) is connectable and disconnectable to/from said output shaft (30) by means of a clutch (50), while the second hydraulic motor (22, 23) is adapted to transmit the movement directly to the output shaft (30). The transmission drive unit further comprises a brake device (70) adapted to block the rotation of the first hydraulic motor (12) when said first hydraulic motor (12) is disconnected from the output shaft (30).

Abstract: An industrial robot device includes a swivel with an attachment mechanism for the attachment of a tool. The attachment mechanism includes at least two different attachment devices for two different kinds of tools. A first attachment device includes a positioning mechanism defining a certain angular position of an attached tool relative to the swivel. A second attachment device is arranged for allowing an arbitrary angular position of an attached tool relative to the swivel. Also contemplated is an industrial robot that is provided with the invented device and to a method for manipulating objects.

Abstract: A hydraulic system is provided for a hydraulic shifter assembly of a split shaft assembly having a power take off system and utilized on a vehicle that has an automatic transmission and limited access to the transmission—preventing a direct connection of a power take off to the transmission. The hydraulic system provides hydraulic pressure from the transmission to the hydraulic shifter assembly and back to the transmission from the hydraulic shifter assembly. The system also provides hydraulic pressure from the transmission to the power take off.

Abstract: A motor vehicle including an internal combustion engine, which utilizes a power take-off mechanism, that converts the reciprocating linear motion of the piston into reciprocating angular motion of the gearing cylinder, being in gear with the partially teethed connecting rod via right angled teeth and rotating motion of the drive shaft which runs coaxially through the gearing cylinder and vice versa. The mechanism has means for causing the piston to pause while the drive shaft rotates. The motor vehicle comprises a fuel heater, an exhaust cleaner including a sinuous tube and liquid for separating impure components of exhaust, a main control module controlling the function of the engine and piston function, a second control module controlling the engine during the minimal running state, thus controlling the pause time of the piston, a third control module controlling the energy flow to the heater, the fuel feeder, and the air feeder.

Abstract: A shift device for a power take-off transmission. An input shaft is connectable to an output shaft with three gear pairs. The output shaft has a recess, in which a PTO stub shaft can be reversibly introduced. A mechanism, actuated by a PTO stub shaft actuates a gearshift sleeve, provided on the output shaft and rotationally fixed to the output shaft, is provided on the output shaft. In one shift position of the gearshift sleeve is rotationally fixed to a gear wheel of a first gear pair. In another shift position of the gearshift sleeve no fixed connection exists between the gearshift sleeve and gear wheel of the first gear pair. By means of a further gearshift sleeve a rotationally fixed connection can be established with a gear wheel of the second or the third gear pair.

Abstract: An embodiment includes a method of engaging a PTO with a drivetrain includes detecting a value representative of the speed of a PTO output gear, and detecting a value representative of the speed of a PTO input gear. The method further includes reducing the speed of one of the PTO output gear and the PTO input gear, and engaging the PTO input gear with the PTO output gear without the use of a clutch to synchronize the speed of the PTO input gear with the PTO output gear.

Abstract: The following steps are performed in the control method: determining a mode of operation from amongst a permanent mode and a transient mode, as a function of a set of variables comprising said estimated values; correcting the value of the speed of rotation of the outlet shaft in such a manner that: if the mode has been determined as being the permanent mode, then the moving average (L?) of the gear ratio (L) over a period (T) of a plurality of unit time intervals lies between a first threshold value (S1) that is negative and a second threshold value (S2) that is positive; and if the mode has been determined as being the transient mode, then said moving average (L?) of the gear ratio (L) lies outside the range of values defined by the first and second threshold value (S1, S2).

Abstract: A motor vehicle torque transfer case pump drive which is mounted in the front of a torque transfer case where it mounts to a motor vehicle transmission and includes a drive arrangement, such as a chain drive, a belt drive or a gear drive. This permits an auxiliary hydraulic pump to be driven directly from the torque transfer case, thus eliminating the need for a power take-off (PTO) adapter to drive the auxiliary hydraulic pump.

Abstract: A transmission, a vehicle, a method of forming a transmission, a clutch pack, and a method of operating a transmission are provided. According to one aspect, a transmission includes a first shaft configured to rotate about an axis; a second shaft configured to rotate about an axis; and a coupling device coupled with the first shaft and the second shaft, the coupling device comprising a plurality of components configured to impart rotational forces received by one of the first and second shafts to the other of the first and second shafts and to provide a plurality of transmission ratios intermediate the first and second shafts, and wherein at least a portion of at least one of the components is coated with a first material different than a second material comprising the at least one coated component.

Abstract: A transfer drive gear is provided at the rear end of a hollow counter shaft disposed under an input shaft. A reduction driven gear is provided at the rear end of a front drive shaft inserted in the counter shaft. The transfer drive gear and the reduction driven gear are engaged with a transfer driven gear which is integrally formed with an intermediate output shaft and a reduction drive gear. The rear end side of the intermediate output shaft is coupled with the front end side of a rear drive shaft through a torque coupling device, so that an FF based on the four-wheel drive vehicle can be formed.

Abstract: A total power takeoff is provided which is positioned between a transmission and a differential gear of a self-propelled vehicle and is operated by the transmission of the vehicle. The power takeoff has a body which has an inlet shaft coming from the transmission and a grooved part, an outlet shaft which is disconnected from the inlet shaft and connected to the differential gear, an engaging ring rotating and sliding on the grooved part and a central driving gear, which is mounted on the inlet shaft for controlling at least one driven gear, for operating a shaft of a user, the engaging ring being movable between a position of engaging and a position of disengaging with the outlet shaft. A clutch is provided with the driven gear controlling the shaft of a user by the clutch. The clutch is arranged inside the body and can be engaged and disengaged without stopping the inlet shaft after the outlet shaft has been disengaged. At least one intermediate gear is provided having a related intermediate shaft.
