Embodiment Construction

[0114] according to figure 1 , the traction drive 1 has a hydrostatic transmission 2 with a hydraulic machine 4 operating as a hydraulic pump in the traction operation of the traction drive 1 and two Hydraulic presses 6 and 8 working as hydraulic motors. The two hydraulic motors 6 , 8 are connected on the one hand to hydraulic pump 4 via working lines 10 and 12 and 14 and 16 and on the other hand are fluidly connected in parallel in a closed hydraulic circuit. The hydraulic machines 4 , 6 , 8 are adjustable with respect to their displacement volumes, wherein the hydraulic machines are each designed as axial piston machines with a swash plate design or an inclined shaft design.

[0115] The hydraulic pump 4 is connected via its drive shaft 18 to a power machine 20 designed as a diesel motor. The first hydraulic motor 6 of the two hydraulic motors 6 , 8 has a first drive shaft 22 and the second hydraulic motor 8 has a second drive shaft 24 . Behind the hydrostatic transmissio...

Abstract

The invention relates to a transmission combination consisting of a hydrostatic transmission and a mechanical transmission with a clutch and a control device for calibrating the slip point of the clutch. Furthermore, the invention relates to a traction drive having such a transmission and a method for calibrating the clutch.

Description

technical field [0001] The invention relates to a transmission combination, a travel drive having the transmission combination, and a method for calibrating a clutch of the transmission combination. Background technique [0002] In order to increase the transmission ratio range of a traction drive, for example a hydrostatic transmission with two hydraulic motors running fluidly in parallel is known. The drive shaft power of the hydraulic motors can be added via the combined transmission of the hydrostatic transmissions and transmitted, for example, to an axle. For example, at low travel speeds, the two hydraulic motors are therefore operated in parallel and thus allow high tractive forces. For a predetermined delivery rate of the hydraulic pump and against the background of a reduction in the absorption volume of the hydraulic motor and a consequent reduction in efficiency, the travel speed achievable with two motors is limited. [0003] Therefore, in order to achieve a hi...
