Description

The The invention relates to a vehicle with a body-mounted syringe for deployment of liquid fertilizers and pesticides o. The like. On agricultural land with the same large tires and a vehicle frame with front in front of the front axle lying vehicle cabin and one on the back provided Aufsattelraum for a liquid tank.

such Vehicles are available in many different types are known and become, for example, for the application of liquid weed killers, Fertilizers, pesticides u. Like. in preparation for spreading a seed and during the growth phase seed applied.

Out the prospectus "The Dammann Profile-Class-Aufbauspritze" is a vehicle with a bodybuilder known when the vehicle consists of the Unimog series, which consists of a vehicle frame, on the driver's cabin, the tank for the liquid Spraying means and the tower for receiving the folding of the boom lie.

This Vehicle has a low ground clearance and thus a low-lying Focus on the driving stability when driving on uneven Soils very favorably influenced, low ground clearance but is when driving on a floor surface with a higher Plant stock very detrimental to the plant population. In addition, this vehicle only has over a small installation space between the driver's cab and the tower construction, so that the capacity of the tank is very limited is. But even the maneuverability of the vehicle is due to the rigid Vehicle frame very limited and a trace in lane Driving when cornering is not given.

From the DE 20 2004 010 228 U1 is an agricultural carrier vehicle for spreading fertilizer and pesticides o. The like. With a front side above or in front of the front axle arranged cab and a rear mounted Aufsattelraum for a tank known in which the wheels are arranged coaxially to the front or rear axle, wherein the carrier vehicle has a ground clearance of at least 80 cm. The structural design of this vehicle has a high and very unfavorable center of gravity, which significantly affects the stability of the vehicle and also the handling particularly when driving on impassable agricultural areas, such as on slopes. Due to the large and equal tires on front and rear axle, which is required to ensure a ground clearance of at least 80 cm, and the rigid rear axle arranged on the vehicle frame, this vehicle has a very limited turning circle and thus a low maneuverability. But even a track in lane driving when cornering is not given. With the order of the engine between the Aufsattelraum and the driver's cab, the possible usable space for the saddle surface is reduced.

From the WO 2005/100133 is an agricultural tractor known, which is formed with a frame articulated steering. Such trained agricultural tractors serve as a pure tractor vehicles without direct loading and regularly have a high weight and are used for towing large equipment.

Even though the frame articulation, as known, excellent maneuverability and despite large and equal tires on the front axle and rear axle realize tight turning circles let as well as a lane in lane driving guaranteed even when cornering is what, especially when grooming and fertilizing one already grown plant stock is very beneficial, was previously u. a. due to the lower tipping stability and the unfavorable Device guidance at the rear attachment the frame articulated steering rejected on vehicles with a body sprayer.

task The present invention is therefore the aforementioned Vehicles with a body spray to improve that at Using the advantages of the known articulated steering a vehicle with a built-up syringe even with large and equal Tires on the front axle and rear axle high tipping stability and ensures a good device guidance in the rear attachment and the space between the rear end of the body space and the cab almost completely for the construction of a large-volume tank is available.

This object is achieved according to the invention with a vehicle with a body-mounted syringe,

• - In which the vehicle frame consists of a front frame and a rear frame, which are connected to an articulated steering,
• - the driver's cab ( 1 ) front in front of the front axle ( 17 ) on the front frame ( 8th ) or on one in a plane with the front frame ( 8th ) extended frame section ( 21 ) is arranged
• - the motor ( 7 ) and the transmission ( 6 ) back to the driver's cab ( 1 ) between the front frame ( 8th ) with a height that extends from the bottom ( 22 ) of the front frame ( 8th ) almost to the wheel cover ( 14 ) of the front wheels ( 19a . 19b ),
• - Is arranged on the rear frame of the liquid tank, the construction area extends frontally from the rear frame to over the rear axle and
• - The tower for the building syringe at the end of the rear frame is arranged.

By the front-side arrangement of the driver's cab on the front frame and the arrangement of the engine and the transmission between the front frame with a height that is almost up to the wheel cover the front axle extends and in connection with the construction area for the tank, the front from the rear frame to over the rear axle extends, and the arrangement of the tower for the build-up syringe at the rear end of the rear frame becomes a very favorable and balanced load distribution both on the Front frame as well as on the rear frame reaches that to a Overall focus of the vehicle leads, which also at a Wheelsize giving a ground clearance of over 70 cm guaranteed, very deep.

tries have surprisingly shown that through the balanced load distribution on the rear frame and the front frame in conjunction with the low overall center of gravity also in a vehicle with bodybuilder, which is formed with a frame articulated steering, a high tilt stability and achieved a good device management in the rear attachment can be. With the high tilt stability and the good Device guidance at the rear attachment is the condition given that, contrary to the previous view, the Rahmenknicklenkung can also be used for agricultural vehicles, the are provided with a building syringe. Consequently, you can the advantages of frame articulated steering, such as realizable tight turning circles even with large and equal sized tires on the Rear and front axle, the good maneuverability of the thus formed vehicles as well as a track in lane driving when cornering and a precise Steering geometry can be used, resulting in a gentle drive over in the care and fertilization of an already grown plant vegetation with minimized damage to plant vegetation essential contributes.

With the use of a frame articulated steering, in which the front frame and the frame over a pendulum rod with each other are connected and wherein the attachment of the pendulum rod respectively Ball joints takes place, which in the median plane of the Frames are mounted so that none of the ball joints coaxial with the central joint is also the force component acting on the vehicle perpendicular to the tangent during cornering and at Turn smaller, which the driving stability in particular at Turning and cornering favorably influenced.

There As is known, the frame articulated steering ensures an exact steering geometry and thus no further steering geometry is to be considered, can easily Equal sized tires on the front axle and rear axle be used, the ground clearance of the vehicle up to 80 cm and when driving on the agricultural Areas are soil friendly, without the special axes, such as For example, portal axes or measures for coaxial Arrangement of the wheels are required.

To an advantageous embodiment of the invention has the liquid tank has a length that extends over the rear frame and the front frame and almost to extends to the driver's cab, wherein the liquid tank starting from the mounting surface at the front end of the rear frame has a tapered lower contour, wherein the Articulated steering and the drive units of the engine and transmission in the Front frame are covered in a free space. By the arrangement of the liquid tank on the rear frame and the preferred tapered embodiment the lower contour, which is spaced over the articulation and the drive units close to the driver's cab extends, the load distribution on the chassis and thus on the axes further favors, leading to another Improved driving behavior contributes. Rather, by the Expansion of the liquid tank over the length of the chassis, the liquid tank at a large filling volume be designed flat in height, which on the one hand the overall center of gravity of the vehicle favors and thus the tipping stability of the vehicle further increased and on the other an aesthetic design of the vehicle allows.
