Displacement | 5.88L |
Rated power (2800R / min) | 118kw |
MAX. torque (1600R / min) | 546N · m |
Minimum fuel consumption rate (1200 ~ 1700R / min) | 224 (g / kW-h) |
Compression ratio | 17.5 |
clutch:Single-chip dry film spring clutch, vibration-vibration spring and friction damping tablets, frictional outer diameter 4) 350 mm, hydraulic long-distance manipulator, booster, hanging pedal.
Gearbox:Mechanical transmission transmission. Five forward gears and a reverse, two to five gear with a lock-free inertial synchronizer with an oblique tooth gear. Center distance: 135mm. Each speed ratio is: i1= 6.602, i2= 3.743, i3= 2.13, i4= 1.297 i5= 1.000, ir= 6.705.
Transfer case:Mechanical, high low, two gears, front axles can be bonded or separated, engaged in the output shaft. Handling mode is long-distance electric control gas, longitudinal speed ratio IH= 1.348 low speed ratio IL= 2.41
Practice:Mechanical, mounted on the right side of the transmission. A forward gear. A reverse, the maximum output power is 22.05kW. Speed ratio: Project 1.518, reverse 1.012.
Slope:Mounted in the back of the car, the engagement sleeve in the manipulator is joined to engage the drum, and the steel wire is provided with a steel wire and the wire is 13mm, the maximum working tension 44100N, and the working length is 50m.
Steering device:釆釆 HFB52 integral power steering gear, the intermediate position transmission ratio is 20.4.
Brake:The parking brake is powered by an air-off spring brake, mounted on the back of Transfer case, and is realized by the hand-controlled valve to control the spring gas chamber. The brake pipeline is used by nylon hoses. The engine exhaust actions are auxiliary brakes. Early production vehicles trailer brakes are dual pipe inflation brakes, in order to match the adaptability of the car gun, after production of trailer brakes for vehicles The control method is complicated in two ways of inflation braking and ventilation.
Rack:The maximum section size of the tap is 232x75x6.5mm. The outer shape of the front bumper considers the coordination relationship with the cab, which increases the mushroom device and the front guard.
Cab:The flat head double-row cabling mechanism developed with the Japanese products is used. The maximum flipping angle is 45. .
tire:tyre uses 12.5R20 meridian diamond block integrated floral plus-shaped tyre, the fetal width is 350mm, and the load capacity and the passability of the vehicle are improved. Having better integrated driving performance.
Wheel net:9.0V-20
tyre air pressure:When the off-road travel, the air pressure is 350kPa, the load carrying capacity is 2000kg.
When the road is driving, the air pressure is 450kPa, carrying capacity of 2200kg
When running in a soft pavement, tyre air pressure can be adjusted to 180kpa
Electrical system:New design
24 volt, single pole, negative iron
Battery: 12V. 180A.H two (low temperature)
Starter: 24V, 4.5KW, teeth 10 teeth
Cold starting device:In order to satisfy the car in a low temperature environment, the car is equipped with a PTC thermosensitive ceramic intake preheating device, which can be successfully started or higher than that of -40 ° C; a heating water jacket is reserved, and the oil preheating mounting hole position is reserved. . There is a plug line in the car tool, which can be heated with an external power supply to heat the coolant and oil simultaneous optional battery heating incubator.
