ZBL-08 "Snow Leopard" - Mobility

Outstanding mobility is ZBL-08 "Snow Leopard" highlight. Because the drive wheels and more, not only increases the towing capacity, but also improves the capacity in difficult sections. The vehicle uses BF6M1015CP water-cooled diesel engines and mechanical transmission, the unit power of 15 kW / t, coupled with front four power steering, so it is easy to drive. "Snow Leopard" on the highway maximum speed of 100 km / h, cross-country average speed 40 km / h. Max gradeability up to 30 , can cross the 1.8-meter-wide moat, through 0.55 m perpendicular wall, highway travel 800 kilometers.

The vehicle also has a water floating crossing ability, "Snow Leopard" is used in tire paddling forward, compared with foreign countries using jet propulsion system speed to slightly inferior, but no preparation can, through waves of not more than three inland rivers and lakes. As the "Snow Leopard" is used AMT mechanical automatic transmission, the vehicle starts and shifting ride with the advanced countries have adopted an AT automatic transmission fluid there is a certain gap.

Wheeled armored vehicles to improve road capacity, ZBL-08 "Snow Leopard" configuration of the computer-controlled central charge and discharge gas system will enable all or individual tire pressure increase or decrease within a few minutes to a predetermined value, and enhance the vehicle in the swamp soft sand zone capacity. Using tires 14.00R20-18PR all steel radial tire safety, it can run after being hit at 30 to 40 km / h speed for 100 kilometers even if all are damaged.

The highlight of the car is the use of the H-type transmission scheme. Its biggest advantage is that the axle in the traditional transmission scheme can be divided into two wheel-side transmission boxes, allowing the middle of the car body to increase the effective use of space in the car . It can lower the center of gravity of the vehicle and enhance the handling stability and cross-country passability of the chassis. Increase the stability during shooting, and can improve the water performance of the vehicle, and the reduction of the height of the vehicle body can also significantly improve the physical protection performance of the vehicle.

Power and transmission system The engine of the new wheeled armored vehicle uses a turbocharged, inter-cooled, water-cooled V-type 6-cylinder diesel engine with a power of 330 kW. The engine has excellent low temperature performance and good plateau adaptability. The cooling fan uses a mixed-flow fan, which can automatically and steplessly adjust the fan speed according to the engine's outlet water temperature. The installation of the power cabin adopts a secondary vibration isolation design, which realizes the overall hoisting and shortens the disassembly and assembly time for maintenance. The main clutch adopts a double-plate dry friction plate clutch. The gearbox adopts a mechanical gearbox with 9 first and 1 reverse synchronizer. In order to meet the international high-end market, an automatic shift mechanical gearbox (AMT) can be used.

The transmission form adopts H-type transmission, the power is output by the engine, and is transmitted to each wheel through the main clutch, gearbox, transfer case, and side transmission case. The speed difference between the inner wheel and the outer wheel when the vehicle is turning is adjusted through the inter-wheel and inter-axle differential to reduce the slip of the inner wheel and the outer wheel, and reduce the slip of the wheel. On muddy, snowy, wet and slippery roads, the passing capacity of the vehicle can be effectively improved by locking the differential in a timely manner. 8X8, 8X6, 8X4 driving conditions can be realized by manipulating the separation mechanism of the first and fourth axles.

In the vehicles developed in the 1970s and 1980s, the suspension devices mostly used independent torsion bars and shock absorbers, and the vehicles developed in the 1990s mostly used independent hydraulic and pneumatic suspension devicesthe new wheeled armored vehicle suspensions were all adopted Independent suspension, I and II bridge adopt sliding column swing arm independent suspension, which has the characteristics of small space in the car, simple and compact structure, and light weight.

The III and IV axles are non-steering axles, with adjustable oil cylinders and single trailing arm independent suspension with small lateral dimensions. This suspension combination mode can effectively improve the comfort of the vehicle and enhance the continuous combat capability of the crew. The parameters of the independent suspension are designed to fully consider the influence of off-road maneuvering, load changes, and artillery shooting. The product has good off-road maneuverability and modification adaptability.

In order to improve the cross-country traffic capacity of wheeled armored vehicles, the new wheeled armored vehicles are equipped with a computer-controlled central inflation and deflation system, which can increase or decrease the pressure of all or a single tire to a predetermined value within a few minutes, and enhance the vehicle in swamps and soft The traffic capacity of the sandy zone. The tire uses 14.00R20-18PR all-steel radial safety protection tires, which can still travel 100 kilometers at a speed of 30-40 kilometers per hour after being shot. The steering system adopts power steering, which greatly reduces the turning radius of the vehicle and improves the survivability of the vehicle in urban street fighting and complex terrain environment.

Due to the increase in driving wheels, it not only increases the towing capacity, but also improves the traffic capacity on difficult roads. The unit power of the car is 16.5 kilowatts per ton, and the front 4-wheel power steering makes it very easy to drive. Two or three-wheel drive can be used on the highway, with a maximum speed of 100 km/h, an average off-road speed of 40 km/h, a maximum climbing degree of 30, and a 1.8-meter-wide trench that can pass 0.55 meters at the lowest speed.

The vehicle has the ability to float on the water and can pass through inland rivers and lakes with no more than three levels of wind and waves without preparation. The water propulsion device adopts a high-efficiency hydraulically controlled double-sided propeller. The free end of the engine provides hydraulic motor power to drive the propeller. The driver controls the handle to drive two water propellers to make the vehicle move forward, change speed, and reverse on the water. And steering to meet the needs of vehicle navigation on the water. The maximum speed on the water is 8 kilometers per hour. The front of the car body is equipped with a reversible wave breaker, which can be opened and closed as required.

The vehicle is equipped with a self-rescue winch device, driven by a hydraulic pump-motor. The driver manipulates the hydraulic handle of the winch to control the retracting and unwinding of the wire rope, implement vehicle self-rescue or help other mildly slumped vehicles get out of trouble.
