摘要:
The invention relates to a towable machine (100) for leveling ground and roads which can be towed by a tractor (200) or tractor unit, comprising a chassis (1) attached to the tractor unit (200), wherein said chassis (1) supports a scarifier-type front portion (5) that directs the scarified material towards a leveling blade (6), said material accumulating in a container (20, 21) demarcated by side walls (7), and wherein the scarifier-type front portion (5) is formed by three scarifier-type blades (5a, 5b, 5c) which are curved and arranged in a delta shape with respect to the forward movement direction and bearing interchangeable spikes or tines at the lower end thereof.

The invention relates to a transporting continuous track (1), comprising a chassis (2) and a semitrailer coupling (3) arranged on the chassis (2) for accommodating a coupling device (4) of a semitrailer (5). The semitrailer coupling (3) is arranged on the chassis (2) in such a way that the semitrailer coupling is pitovably supported along a transverse axis (8) of the transporting continuous track (1). The semitrailer coupling (3) is arranged on the chassis (2) in such a way that the semitrailer coupling can be moved longitudinally with respect to a longitudinal axis of the transporting continuous track (1). The semitrailer coupling (3) is arranged on the chassis (2) in such a way that the semitrailer coupling can be height-adjusted with respect to a height axis of the transporting continuous track (1). The semitrailer coupling (3) has a fixing device, by means of which an inclination of the semitrailer coupling (3) can be fixed.

The invention relates to a work machine (101) comprising a front section (102) with a front frame (103) and a first set of ground engaging members (135, 235), a rear section (107) with a rear frame (108) and a second set of ground engaging members (136, 236, 137, 237), and at least one pivot joint (121, 125) between the front section (102) and the rear section (107) allowing the front section to pivot with regard to the rear section. One of the front section (102) and the rear section (107) comprises a power source (140), and the other of the front section and the rear section comprises at least' one electric motor (146, 148, 150, 152) adapted for driving at least one of said ground engaging members.
摘要:
In said process, the relation between the fluid pressure and the variation in the ratio, or in the shift, between the speed of the tractor (1) wheels and those of the semitrailer (2) in the hydraulic circuit is defined, said shift is determined and a correction signal proportional to the shift is applied to the capacity of the pump (14) and/or of the hydraulic engine (16) when the fluid pressure is no longer contained in a predetermined range, between a higher and a lower pressure.
摘要:
A power transmission coupling for driving the wheels (1) of a trailer from a power take off on a tractor unit towing the trailer unit. The coupling comprises a clutch (6) having an input for connection to the power take off (15), and an output (5) for connection to a power transmission input of the trailer unit. The tension in the coupling when it connects the tractor and trailer units is monitored, and the slippage of the clutch (6) is controlled in response to the monitored tension so as to maintain the speed at which the trailer unit is driven substantially the same as the speed at which the tractor unit is driven.
