The HX family are a range of purpose-designed tactical military trucks manufactured by Rheinmetall MAN Military Vehicles (RMMV). The HX range was disclosed in 2003, and the first order was placed in 2004. The HX range replaced the earlier FX and LX ranges in production. The HX2 range, which currently complements the original HX range, was announced in 2012. The first HX2 range trucks were delivered in April 2016.[3] The HX and HX2 ranges complement the SX range.[1]

History

RMMV (then MAN) confirmed it was developing the HX range at Defence Vehicles Dynamics (DVD) 2003 and a developmental example shown later in the year at DSEi 2003. The earlier LX range was superseded by the HX range in 2004. The FX range was superseded in 2005.[1]

The first order for the HX range came from the British Army which announced in October 2004 that it had selected the MAN ERF UKUK Ltd proposal to meet the Support Vehicle requirement. The contract was awarded in March 2005.[1]

At Eurosatory 2012 RMMV displayed publicly for the first time an example of the HX2 range.[1]

For clarity, RMMV is a 49%/51% joint venture established in January 2010 between MAN Nutzfahrzeuge AG (now MAN Truck & Bus) and Rheinmetall AG.[4]

Description

The HX/HX2 ranges of trucks combine militarised commercial driveline and chassis with the latest version of a modular military-specific cab. The HX/HX2 ranges are based on chassis and driveline components of MAN's commercial TG WorldWide heavy truck range which was first introduced in 2000.[1][2]

MAN water-cooled diesel engines of various power outputs and emissions compliance are used across the range, these including the D0836, D2066, D2676 and D2868. The engine remains positioned conventionally (longitudinally between the chassis rails), however, the cooling pack is located transversally at the rear of the cab. This location offers protection from damage and blockage of the radiator with mud etc. when operating off-road. It also allows for a larger volume radiator to be used, which enhances hot-climate operating capability.[1]

A ZF AS-Tronic automated constant mesh gearbox (branded TipMatic in MAN’s commercial product line up) with 12 forward and two reverse gears is standard fit, this coupled to a MAN two-speed transfer case. A powershift-type fully automatic transmission is an option.[1]

Drive axles are MAN single tyre hub-reduction, and with the exception of the heavier tractor units which are full-time all-wheel drive for traction and torque distribution reasons, all models have selectable front axle(s) drive. All axles have cross-axle differential locks and there are longitudinal differential locks in rear (and front on 8×8 and 10x10 chassis) axle combinations and the transfer case. Axle weight ratings are 9000 kg or 11,000 kg for front axles, and 10,000 kg for rear axles with single wheels/tyres.[1]

Front steer-drive axles (including the 2nd axle on 8x8 chassis) are sprung by a combination of parabolic leaf springs with progressively acting rubber assistors and hydraulic telescopic shock absorbers. Rear axles are sprung by inverted multi-leaf trapezoidal springs with radius rod and an anti-roll bar. A conventional rear bogie set-up is employed for 6×6 and 8×8 chassis. The HX45M 10×10 will feature hydropneumatic suspension for the rear three axles.[1]

The standard 1400R 20 tyres may be replaced by 395/85R 20, 525/65R 20 or 1600R 20 tyres if required. A central tire inflation system (CTIS) or semi-automatic tire inflation system and run-flat inserts are options.[1]

All models can climb a 60% gradient, traverse a 40% sideslope, have an approach angle of 40 degrees, and ford 750 mm of water without preparation, this increasing to 1.5 m with preparation.[1]

With the exception of the modular military cab, the location of the cooling pack and a small number of military specific ancillary items and modifications, for cost efficiency reasons RMMV has strived for maximum commonality with the TG commercial product.[1]
