A conventional structure is expected to be resistant to 2G. Our competitors can achieve 3G for some extreme applications. BREMACH cab was developed to withstand to more than 5G. He does not give only the impression of being the most resistant vehicle ever built, but it really is! BREMACH secret is its unusual tubular structure. The tube is the most resistant mechanics material. In fact, the side roll-bar is made starting from a tube which is shaped and rolled through several steel masks, gives the resistance.

BREMACH T-Rex Tanıtım Broşürü
The T-Rex modular structure is made starting from a 100 mm diameter tube formed using an elaborate train roller. The advantage is the high resistance. In fact, thanks to this, the steels sheets are welded each other in order to avoid deformations even in case of extreme stresses.

Chassis: Extremely rigid with its unusual tubular section, the chassis has a reinforced chassis frame, completly designed and developed by BREMACH for vehicle use in extreme conditions.
Axles: Rigid type with parabolic leaf springs, telescopic double acting shock absorbers, to ensure the maximum stability even for extreme use. The axles are entirely designed and developed by BREMACH.

Parabolic Leaf Springs Parabolic The profile of a parabolic leaf spring is similar to the pack of leaves in a multi-leaf unit. The steel used in the leaf is tapered with the thickest section at the centre of the leaf. Very simply, this means a parabolic spring will have a similar function to that of the multi-leaf spring in providing progression as load is applied. Parabolic springs have a more supple characteristic than multi-leaf springs and may provide a softer ride. The use of less steel in the manufacture means they are lighter. The trade off comes in load carrying capacity and a big, heavy 4x4 carrying lot s of weight may be better suited to a multi-leaf set up.

Brakes: Developed by BREMACH in collaboration with Bosch, independent double hydraulic, with brake on four wheels and autoventilated on the front axle, longitudinal decelaration sensor and deselectable ABS.
Tyres: Available different types, suitable for any use: from Michelin XZL for off-road use to those used on sand, road or mixed route.

• Today, most smaller vehicles such as small SUV s and sedans use a unibody (or monocoque) construction.
• Heavy-duty vehicles like trucks and busses still use the idea of body-on-frame.
• Regardless of the construction technique, steel is still the predominant material used in automotive frames.

ARAÇ KAROSERİ Aero dynamics: 1. Windshield glass is aerodynamically designed with a pin that prevents the
wiper from lifting, thus minimizing wind noise during high speed driving. 2. Rear spoiler: Continues roof line and reduces wind noise 3. Engine undercover: Smooth surface increases the aerodynamics on the
underside of the vehicle and contributes to a reduced fuel consumption. Further it offers protection when driving off-road.
4. Wheel deflectors: Deflect wind around the wheel openings for better aerodynamics.
The application of high density hood insulation and sound deadening foam a the pillars further contributes to a low noise in the passenger compartment. All directional safety design: • Hollow side members gradually increased in diameter from front to back for
improved impact absorption. • Rear frame member reinforced. • Fuel filler neck base moved forward • Side members are designed straight for better impact absorption High tensile steel is utilized for greater safety from impact and weight reduction. Center B pillar is designed as one piece internal roll bar. Hyundai provides a 12 year anti perforation warranty for the vehicle body.
