Embodiment Construction

[0016] exist figure 1 In , reference 1 denotes a vehicle comprising a power takeoff 2 that can be used to drive at least one consumption point 3 when engaged. In the case of log trucks for example, there may thus be consumption points in the form of cranes, which are not shown.

[0017] Reference 4 denotes the engine of the vehicle, adapted to drive a gearbox 7 , itself adapted to drive a power takeoff 2 , via an automatic clutch 5 with an automatic clutch cylinder mechanism 6 .

[0018] The power take-off 2 is adapted to power a pump mechanism 8 adapted to pressurize pressure medium represented by a pressure medium tank 9 in order to supply pressurized pressure medium to at least one consumption point 3 . In this regard, the pump mechanism 8 is formed with a pressure line 11 extending from said pump mechanism to the point of consumption 3 , a return line 12 extending to the tank 9 , and a suction line 13 extending from the tank 9 to the pump mechanism 8 in order to generate ...

Abstract

Method for controlling a power takeoff (2) of a vehicle (1) driven via a gearbox (7) provided with an automatic clutch (5) and adapted to supply power to a pump mechanism (8) for pressurizing the pressure medium at least for consumption point (3). The method is distinguished in particular by controlling the engagement / disengagement of the power takeoff (2) by means of the automatic clutch (5) for controlling the pressurization. The invention also relates to a device for controlling the operation of a power output device (2) of a vehicle (1). The invention also relates to a vehicle.

Description

technical field [0001] The invention relates to a method for controlling the operation of a power takeoff of a vehicle. [0002] The invention also relates to a device for controlling the operation of a power takeoff of a vehicle. [0003] The invention also relates to a vehicle (or vehicle). Background technique [0004] Techniques substantially as described above are prior art. Many types of utility vehicles, such as log trucks and other types of goods vehicles, are provided with a power take-off adapted to be driven via the vehicle gearbox and which itself drives a hydraulic pump, such as the consumption of a loading / unloading crane. The points are powered by the hydraulic pump via pressurized pressure medium. [0005] When the power take-off is engaged, it thus drives a hydraulic pump which supplies power to the consumption point at the point where the power is utilized, for example with the pressure of the hydraulic medium. [0006] Sometimes when no power is used a...
