摘要:
An elongate construction element (1; 19, 20) including a first elongate profile (2) with a first section (2′) located in a first plane and a second section (2″) located in a second plane different from the first plane, a second elongate profile (3) with a first section (3′) located in a first plane and a second section (3″) located in a second plane different from the first plane, and at least one third profile (4; 4′, 4″, 4′″, 14). The respective first sections (2′, 3′) of the first and the second profile are located in essentially the same plane, and the third profile (4; 4′, 4″, 4′″, 14) constitutes a web which is fixed to and interconnects the first sections along at least a part of the extent of the construction element. The invention also relates to a frame for a vehicle, which frame comprises at least a pair of such construction elements.
摘要:
A draw coupling arrangement (1) for a vehicle including a coupling jaw (2) and a coupler (4) which can be lifted by a lifting device (5). The coupler is intended for coupling together with a towing eye on a towed vehicle, and where the coupling means (4) consists of a coupling bolt with two towing sections (6a, 6b), where the towing sections (6a, 6b) have different diameters.

A device for mounting on a vehicle is shiftable between at least a first active position, in which it constitutes an underrun protection, and a second active position, in which it constitutes a vehicle support. Hereby, the functions of an underrun protection and vehicle support may be provided in a combined device.

A method and a system determine the load transferred from a semi-trailer to a first axle of a towing vehicle which has at least one further, second axle. The semi-trailer is partly supported by the towing vehicle at a “fifth wheel”. A first value representing the load transferred from the semi-trailer to the second axle is determined by a load sensor and a second value representing the position of the “fifth wheel” in relation to said axles are also determined. Based on these first and second values a value representing the load transferred from the semi-trailer to the first axle is calculated by a calculator. The calculation may be based on the equation L1*d1=L2*d2 or L1=L2*d2/d1.
摘要:
An axle load control system and method for a load-carrying truck having a front axle and two or more rear axles is provided. The system includes a wheel suspension system with a suspension control processor, a load sensor arranged at each of the axles for detecting one or more load indication parameters, the load sensor providing the parameters to the suspension control processor which translates the parameters into actual axle load values for the individual axles. The control processor is arranged to compare the actual axle load values with a predefined maximum allowable axle load value for each axle, and to control—or indicate to a driver the need to control—the wheel suspension system so as to effect an individual adjustment of the suspension characteristics for each axle in such a way that excess axle load on an overloaded axle is transferred to one or more of the remaining axles, thereby adjusting the theoretical wheelbase of the truck.

The invention relates to a power generating unit mounted to a source of rotational energy and arranged to supply hydraulic pressure and flow to at least one driven accessory. The power generating unit comprises a housing removably mounted on the source of rotational energy, an input shaft adapted to be connected to the source of rotational energy, said input shaft comprising a first end provided with means for engaging the input shaft to a power output interface on the source of rotational energy, a second end connected to a hydraulic pump and means for selectively engaging the input shaft to the hydraulic pump. The input shaft, the means for selectively engaging the input shaft, and the hydraulic pump are arranged as an integral power generating unit within said housing. The invention further relates to a vehicle provided with such a power generating unit.
摘要:
A system is provided for controlling the load split between the axles and thereby the theoretical wheelbase of a vehicle having two front axles being suspended in suspension units at least some of which have springs with adjustable stiffness. A method for controlling the load split between the axles and to a motor vehicle including such a system and/or by use of such a method is also disclosed.
摘要:
A device for controlling the height of a load or load carrier behind the cab of a truck includes a sensor supported on a power operated air deflector on the roof of the cab. The sensor is arranged, during vertical movement of the rear end of the air deflector, to sense the maximum height of the load or the load carrier behind the cab and to send signals representing the maximum height to an indicator inside the cab.
摘要:
A fifth wheel assembly for coupling a trailer to a truck tractor is provided and includes a fifth wheel and a supporting structure for supporting the fifth wheel on the rear part of the tractor truck. The supporting structure includes a sliding arrangement enabling the fifth wheel to be repositioned between different positions. A number of sensors are positioned on the supporting structure and on the fifth wheel and are included in a control system for predetermined information and control of operating conditions.
