Badger (armored) (Dachs )

The Badger armored engineering 2A1 or Pionierpanzer badger belongs to the group of combat support vehicles and is the successor to the pioneering Tank 1 . He is an armored pioneer work unit and is based on the Leopard 1 chassis. His responsibilities include: the recovery of damaged vehicles, the manufacture of entries and exits as well as entrances and exits to water crossings or steep and muddy coastal waters, the Befahrbarmachen the water bottom and the donning and removing obstacles and barriers on the battlefield. Used the vehicle with the pioneers and pioneers of armored army the army and in theCanadian armed forces under the name Badger - Armoured Engineering Vehicle (AEV) . He also is used in the Chilean army.It is the first pioneer by the Bundeswehr, which has been optimized specifically for the applications of the pioneers.

Development

After the failure of the project armored pioneer machine (GPM), the Bundeswehr still sought a successor for the first Pionierpanzer According to the mission fields of the pioneers , the conveyance of the movements of one's own fighting force and inhibiting the enemy by creating barriers, should all work at ABC - and armor protection to be executable. Was requested by the Ministry of Defence (MoD), an inexpensive full-fledged armored engineering that takes into account the experience of the GPM project. The total contract value comprised 140 vehicles with a total value of 190 million DM delivery target was 1990.
The company Maschinenbau Kiel (MaK), built in the period from 1981 to 1983 his first two prototypes and tested them in 1984 in experimental work. The third prototype was followed in 1987 after contracting by the Federal Office of Defense Technology and Procurement . The design of MaK based on a modified Bergepanzer 2 and received, instead of the crane with a telescopic bucket company Wieger Maschinenbau. The error-prone for the drill Engineer Vehicle 1 was not pursued. The ironworks Kaiserslautern (EWK) appeared responsible for the swing and the dredger. Jungenthal Jung took over again - just like with the GPM project - the renovation of the trucks. 75% of the components of the Leopard series found themselves in the roof. The combat weight t reached the 43rd
MaK made ​​as a general contractor in 1988 the armored engineering. According to the planning objective of the MoD this arose from the conversion of 104 armored recovery vehicle 2 and the existing 36 Pionierpanzer first The first production vehicle of armored engineering 2A1 roof was on 13 April 1989 passed in Ploen, ahead of the target delivery of the Bundeswehr. Labeled A1 has been chosen to demonstrate the performance of the assembly relative to the recovery tank. The ladder on the telescopic arm and the bow MG accounted for roof and was only found on a prototype. The proven hydraulic and mechanical cutting angle was dropped also. Delivered a total of MaK - since 1992 a part of Rheinmetall Land Systems - 149 vehicles of this type in Germany and Canada . The Order of Canada for nine vehicles had a value of 49 million DM.

Technical Description

Interior and occupation

The crew consists of three men: the driver, the commander and a third crew member as an additional work force. The driver sits in the front right vehicle under a one-piece hatch. He controls the tank according to the specifications of the commander and served the pioneering technical institutions, including the sign, and the winds. He is also responsible for maintenance on the hull of the tank. The commander sits slightly to the left directly behind the driver. He leads the tank, keeps the radio connection to the higher-level management positions and may, if necessary to override the driver in control of the telescope. He is also responsible for loading and operation of the anti-aircraft machine gun. Third soldier sits in the rear part of the structure. The access to the combat zone via the two skylights or the hatch on the left side of the vehicle.
To have the communication vehicles of the Bundeswehr with a VHF SEM 80 (transmitter / receiver, mobile 80). All angles are in the range of implements mirror mounted to tilt in order to work under armor protection. As night vision devices used intensifier .

Protective Equipment

The trough of the roof is made ​​of welded steel armor and has a single-layer armor. The level of protection for the chassis is similar to the Leopard 1 The armored structure reaches armor thickness from 25 mm to 35 mm and 10 mm for the sides of the roof. The hydraulic cylinder of the telescopic arm received a splinter protection. The standard equipment include a NBC protection - and ventilation system and a fire detection and suppression system. The exhaust system with air infiltration, reduces the infrared signature and thus supports the passive armor protection.
The Canadian Pionierpanzer also received for the KFOR and ISAF deployment provides MEXAS additional armor from IBD Deisenroth Engineering .

Armament

The armament of the roof is mainly intended for self-defense. The three-man crew of the German armed forces has a machine gun MG3on the anti-aircraft gun mount the commander's cupola, a smoke grenade launcher with six cups and throw their hand weapons . The Canadian Badger additionally comes with the bow gun. As a machine gun there is the Belgian FN MAG under the name C6 GPM .

Engine and chassis

The torsion bar suspension support roller drive of the leopard was adopted without changes. Each side it has seven double-tyred rollers and four support rollers. The suspension travel is limited by volute springs and stops. The drive wheel is at the back of the chain.

To avoid the loss of the chain, driving in difficult terrain ', received the prototypes on large discs on the drive wheel. The series vehicles were equipped with chain start carriers (driving wheel cleaners), which are attached as required across the drive wheel drum. When not in use it can be stored on the rear right tail. As a caterpillar is a "living" Endverbinderkette (type: D 460A ) with interchangeable chain upholstery manufacturer Diehl. The ground pressure is 0.92 kg / cm ².

The complete drive train was also taken one to one. Powered by a 10-cylinder multi-fuel engine of the type MB 838 CaM-500 with two mechanical chargers reached the roof a top of 62 km / h The engine delivers 830 hp at 37.4 liters capacity and allows a power to weight of 19.3 hp / tonne. The fuel supply of tanks was increased to l 1410th The street range is therefore 500 km, with a consumption of 280 liters per 100 km. To ensure a steady supply of oil even in difficult terrain and in an inclined position, the engine is a dry sump forced lubrication equipped.

The power supply of 24 V electrical system is provided by a liquid-cooled 9-kW alternator. The battery system consists of six batteries of 12 volts with a total of 300 amp hours.

Power is transferred to the chain uses the badger the Manual 4 HP-250 by ZF Friedrichshafen . Flanged to the engine, it has four forward and two reverse gears are shifted electro-hydraulically. Is coupled with a hydraulic torque converter lockup clutch. The brakes of the vehicle meets the minimum requirements of the Road Traffic Licensing Regulations and are designed as a single-circuit hydraulic disc brakes with brake oil pump support and nitrogen reserve.

Pioneer Equipment

The heart of the roof is his pioneering features. These include the telescopic arm with bucket, the clearing and support plate, the mountains and wind equipment and various means such as a pioneer of cutting and welding equipment and work lights. The hydraulic system has been improved in performance and works on the load-sensing principle, which means that multiple hydraulic cylinders (up to three) can be operated simultaneously and independently of each load. The working pressure is 300 bar.

A special feature of the Engineer Vehicle 2 is the possibility of using an underwater elevator shaft and special preparations are working on engine and chassis even in a water depth of 4 m in continuous use. The control of the telescope is done by remote control from the bay.Without these measures, the working depth is 0.8 m and 2.25 m in Tiefwatausrüstung. A flushing the back of the battle space, originally designed for armored pioneer machine allows, also working in very dirty and fast flowing water. The circulating water is used for cooling of the engine and hydraulic oil.

As with the prototype of the GPM of the EER excavator plant was installed front right of the chassis. The similarity of the Teleskopbaggerarms is the most prominent feature of this design by MaK. The extendable to 9.20 m in length construction allows a swivel range of 195.5 °, and a rocking angle of + / -60 °. The earthworks are incurred bucket with teeth and drain holes are available. The capacity is 0.6 m³ to 1.1 m³. The excavator output reaches 140 m³ / h, the tensile strength of 125 kN. By a clamping device with twoclaws can beam, trees and other obstacles are removed. An optional device may be on the arm with the bucket used as a third claw together. In addition, the dredger will be used by the pioneers also for pressing and tearing.

Zurüstbarer a swivel hook on the telescopic arm also allows use as a crane that allows you loads of up to 7.8 t at 3.98 m radius and up to 2.6 tonnes at 7.92 m can raise throat. Through a technical change, the maximum load has been over the use of reduced time t 2, in which case the bridge area of the tank Quick bridge beaver t with 2.5 considered to be exceptional load. When an overload in crane operation, an overload warning system stops - which are reset manually by the operator must - crane operations.
The shape of the rough and support shield was selected for the working areas of the pioneers and can be expanded by folding extensions of 3.25 m to 3.75 m. The cutting angle is 50 ° fixed, the height 94 cm. Equipped with a tear, which loosens the material and swirled can antitank ditches and pushed obstacles. The clearing capacity is 270 m³ / h Applying a fight prior to a battle tank takes about 15 min  to complete. Two zurüstbare fangs enable on-demand in driving backwards to a depth of 45 cm and a soil loosening. The dredging and use of wind shield serves as ground anchors, thus ensuring a stable level of pioneer tank.
The wind plant was built by MaK unchanged and an improved chuck adds that provides for winding and unwinding a uniform cable tension. The tensile force of the winch drum is 345 kN (34.5 t) in the single drawing and 690 kN (69 t) in the double move with pulley . The operating speed is 14 m / min in the first gear and 44 m / min in second gear. A role above the Räumschildmitte reduces the wear of the 90 m long and 33 mm thick rope rolling. When used underwater, the cable drive are covered and therefore not usable. The Canadian has Badger notwithstanding a capstan winch with a pulling force of 350 kN (35 t) in the single drawing.

Other features also include a cutting and welding machine (54 V/360 A), angle grinders , impact wrenches , car lifters, pulleys, towing scissors, shackles and hand tools in addition to an expanded set of tools. The loss of internal storage space was offset by three boxes on the vehicle, which was supplemented in 2009 with the German armed forces through a waterproof storage box in the engine cover. Lockable tool boxes on the hull sides should also protect against loss and damage to the equipment in use.
