Definitions
- the present invention relates to an impact attenuating device to be connected to a vehicle, especially an impact attenuator which is transported as a trailer.
- An impact attenuating device of this kind is disclosed in WO 01/87671 A1.
- the disclosed impact attenuator has a front member connecting the impact attenuator to a vehicle.
- the impact attenuator is connected in a transporting position, in which the impact attenuator is connected as a trailer to the vehicle, or in an operating position, in which the impact attenuator is connected as a rigid extension of the vehicle.
- Impact attenuators are used, at e.g. roadwork areas, to protect road-users, men at work and equipment.
- the impact attenuators task is to, in a soft way, stop vehicles from entering the roadwork area. This is achieved by an attenuation device that dampens the force of collision from a colliding vehicle by deformation of the construction, e.g. by a metal construction with zones of deformation or an elastical construction of polymeric material.
- Impact attenuators are generally difficult to transport because the distance between the vehicles rear axis and the rear point of the impact attenuator, the overhang, is long.
- a long overhang causes great problems in sharp bends, intersections, roundabouts etc.
- the overhang sweeps over a large area outside the vehicle's own lane, and in some traffic environments, it may be difficult to transport the device.
- Another problem is that an impact attenuator arranged at the back of a vehicle affects the axle pressure. There is a great pressure on the rear axle and a small pressure on the front axle, which may make the steering difficult.
- the present invention relates to improvements of the prior art.
- Known impact attenuators of this type shifts between a transport- and an operating position by moving the whole impact attenuator away from the vehicle.
- the drawback with this solution is that the turning radius is limited due to the fact that the force transferring beams may hit the vehicle.
- the invention solves this problem by arranging an extension device in the impact attenuator between a front part, fixedly connected to the vehicle, and an attenuating device.

- FIG. 16 shows a second embodiment of the connection to vehicle.
- FIG. 1 discloses an impact attenuating device ( 1 ) connected to a vehicle ( 2 ), preferably a lorry.
- the impact attenuator ( 1 ) comprises a front part ( 3 ), an attenuating device ( 4 ), a rear part ( 5 ), and an extending device ( 6 ).
- the front part ( 3 ) is connected to the vehicle ( 2 ) in order to transfer the forces of a collision from the impact attenuating device to the vehicle during a collision.
- the front part ( 3 ) comprises two pivot wheels ( 31 ) with suspension, and a traffic routing board ( 9 ). Between the front part ( 3 ) and the attenuating device ( 4 ), an extension device ( 6 ) is arranged.
- the extension device ( 6 ) can be in a transport position or in an operating position. In the transport position, FIGS. 1 and 2, the extension device ( 6 ) is in an extended state and the attenuating device ( 4 ) is pushed away from the front part ( 3 ). The attenuating device ( 4 ) is connected to the front part ( 3 ) via the extension device ( 6 ).
- the attenuating device ( 4 ) is in the shown embodiment a ring of an elastic material, but it could also be of a different construction, e.g. a metal construction with deformation zones.
- FIG. 3 discloses the impact attenuating device during a turn.
- the attenuating device ( 4 ) moves like a trailer.
- the extension device ( 8 ) is connected to the attenuating device ( 4 ) via a horizontal joint ( 63 ).
- the attenuating device ( 4 ) hangs freely between the rear part ( 5 ) and the front part ( 3 ) and is not effected be any moment, except from the effect from it's own weight. This means that the attenuating device does not have to be designed to manage the moment forces and can therefore be made lighter.
- FIG. 4 discloses section A-A in FIG. 1.
- the front part ( 3 ) comprises two pivot wheels ( 31 ), with suspension ( 32 ), traffic routing boards ( 33 ), and a lowered light arrow ( 34 ).

- two operation wheels ( 51 ) has been lowered down to the road way.
- the operation wheels ( 51 ) are used.
- FIG. 6 discloses the collision plate ( 53 ) carrying all the functions necessary, e.g. direction indicator, brake light, position light and reverse light. Furthermore, it has an uneven surface to prevent a colliding vehicle from sliding of the collision plate and continuing along the impact attenuator.
- FIGS. 8 and 9 show the impact attenuator ( 1 ) connected to a vehicle ( 2 ) in the operating position.
- the extension device ( 6 , 61 ) is in its shortened position with the front part ( 3 ) and the attenuating device ( 4 ) pushed against each other.
- the front part ( 3 ), attenuating device ( 4 ), and rear part ( 5 ) is a rigid extension of the vehicle ( 2 ).
- the front part ( 3 ) and the attenuating device ( 4 ) are provided with a docking device ( 7 , 8 ).
- FIG. 10 shows a section D-D of FIG. 8.
- FIGS. 11 - 13 show different sections of the rear part in operating position.
- FIG. 11 discloses the rear part ( 5 ) without the collision plate ( 52 ).
- the two transport wheels ( 52 ) are up and the two operation wheels ( 51 ) are down.
- the operation wheels has a pivot function, i.e. they can turn around a vertical axis, this is indicated in FIG. 11 by showing the operation wheels in different positions.
- the operation wheels ( 51 ) are vertically adjustable by a hydraulic telescopic device ( 55 ).
- the shown embodiment has two operation wheels ( 51 ). Another embodiment is to arrange a single operation wheel in the middle.
- FIGS. 1 - 2 and 8 - 9 disclose a first embodiment of the extension device ( 6 ).
- the Figs. shows an extension device ( 6 ) comprising a hydraulic telescopic device ( 61 ).
- One end of the telescopic device ( 61 ) is connected via a vertical joint ( 62 ) to the front part ( 3 ). It is around this joint ( 62 ) the attenuating device ( 4 ) turns during transport.
- the other end of the telescopic device ( 61 ) is connected to the attenuating device ( 4 ) via a horizontal joint ( 63 ).
- the telescopic device ( 61 ) rests on a half circle shaped support element ( 64 ).
- the support element ( 64 ) comprises end stops ( 65 ) in order to prevent the attenuating device ( 4 ) from hitting the front part ( 3 ) during sharp turns.
- the FIGS. 1 - 2 and 7 disclose the impact attenuator ( 1 ) in transport position, i.e. the telescopic device ( 61 ) has moved the attenuating device ( 4 ) away from the front part ( 3 ).
- a docking device ( 7 , 8 ) is arranged on the attenuating device ( 4 ) and the front part ( 3 ) to ensure that, in operating state, the collision forces from the rear part ( 5 ) and the attenuating device ( 4 ) is transferred to the vehicle ( 2 ).
- FIG. 14 discloses a second embodiment of the extension device.
- the extension device ( 6 ) comprises a hydraulic cylinder ( 100 ), via a first joint connected to the front part ( 3 ), and a second joint to a link arm ( 101 ).
- the link arm ( 101 ) is movably connected to the front part ( 3 ) via a joint ( 102 ) and a cardan joint ( 103 ) connected to a boom ( 103 ), which is connected to the attenuating device ( 4 ).
- the attenuation device ( 4 ) is pushed against the front part ( 3 ) as in FIGS. 8 and 9.
- the boom ( 104 ) is lifted and pushed backwards in order to push the attenuating device ( 4 ) away from the front part ( 3 ) and thereby to the transport position.
- FIGS. 15 and 16 disclose two different embodiments of the connection between the front part ( 3 ) and the vehicle ( 2 ).
- the front part ( 3 ) is rigidly connected to the vehicle ( 2 ) and rolls on wheel with a pivot function.
- the impact attenuator is first connected to the vehicles towing device ( 36 ), thereafter the force transferring beams ( 35 ) is pushed against the frame side members ( 36 ) of the vehicle, and the towing device is thereafter locked hydraulically or mechanically.
- FIG. 16 the vehicles towing device is not used. Instead the force transferring beams ( 35 ) is directly connected to a coupling device on the side frame members ( 38 ) of the vehicle. The force transferring beams ( 35 ) is thereafter locked to the frame side members ( 36 ) with a locking device ( 38 ). Further embodiments of how to connect the front part to the vehicle are disclosed in the mentioned WO 01/87671 A1.
- the invention described above discloses an impact attenuating device, which can hold a transport position with the attenuating device hanging freely and flexible as a trailer, and an operating position with the attenuating device connected as a stiff extension, in sideway, of the vehicle.
- the impact attenuator does not affect the axle pressure of the vehicle, i.e. the impact attenuator carries its own weight. Therefore, a vehicle with maximum allowable axle pressure, i.e. fully loaded, can be used.
- the invention also discloses a rear part with hoistable transport wheels and wheels without a pivot function. For safety reasons this is a better solution than prior locking of the pivot function, due to the fact that it is now impossible to drive with the pivot function in the transport position. With a locking of the pivot function, there is a possibility of signal error of human error, which may cause the locking to malfunction during transport.
- a number of the impact attenuator device's functions are preferably controlled by hydraulic.
- One alternative is to connect the impact attenuator to the hydraulic system of the vehicle.
- the drawback is that the impact attenuator and the vehicle have to use the same hydraulic fluid. If several different vehicles use the impact attenuator this could be a problem.
- a second alternative is to arrange an internal hydraulic system ( 10 ) on the impact attenuator. The system is powered by the vehicles hydraulic system, but the hydraulic fluids from the different systems are never mixed.
- the impact attenuator according to the invention can be modified and connected to the front of the vehicle during operation, as a protection against oncoming traffic.
