Hande axles is an important heavy axle production base in China, with accumulative production of more than 3.9 million axles, ranking first in domestic axle assembly export for many consecutive years.

(1) Weichai four-valve engine, with strong power and large output torque, has the best vehicle power and explosive force in the industry. The engine adopts wedge mount, and the NVH (noise, vibration and acoustic roughness) performance, anti-loose performance, comfort and vehicle reliability are greatly improved.

(2) Fast transmission, using double intermediate shaft structure, high reliability; Large speed ratio range, suitable for different working conditions, strong climbing ability; Small ratio difference, high fuel economy.

(3) Hande casting bridge, the fatigue life of the axle housing reaches 1.318 million times without damage, strong bearing capacity, the axle adopts the FAG low resistance and maintenance free bearing technology of European synchronization, independent lubrication system, and lower oil consumption.

2. Cummins is the world's largest independent engine manufacturer and the only company in the global engine industry with all five key engine subsystems. Cummins ISM engine, ECM electronic control system, intelligent protection, multi-stage fuel filter system, strong fuel adaptability, low fuel consumption.

3. Standard WABCO valve, increase the test air pressure interface, easy to measure air pressure, easy to test the braking performance and troubleshooting. Voss joint, greatly improved reliability, better vehicle air tightness, good pressure holding capacity.

4. The use of drying tank + oil-water separator two-stage water removal and oil removal guarantee, to ensure the dry and clean compressed air, greatly improve the reliability of the braking system, reduce safety risks, improve driving safety.

5. Suspension can choose plate spring suspension, composite suspension, air bag suspension in three forms.

(1) plate spring suspension has the strongest bearing capacity.

(2) Composite suspension has strong bearing capacity and good comfort.

(3) The airbag suspension has light weight and small bump range.

6. A new generation of electrical system: it adopts the advanced CAN bus technology of German BOSCH company and the automatic fault detection function. The new and upgraded electrical system has been verified by the vehicle market of 12 million kilometers, with stable performance, safe operation and convenience.

7. Using simulation and multi-body dynamics technology, the whole system is adjusted from the walking system, suspension system, suspension system to the driver's seat, which has passed the verification of the latest European test standard (ISO2631), and the ride comfort index of the whole vehicle is internationally leading.

8. Cooling system adopts left and right symmetrical air chamber arrangement to reduce the length of the intake pipe, small air resistance, compact pipeline arrangement, higher ground clearance, and stronger vehicle passability.

9. Adopt APU module, which is an air handling unit integrating air dryer and four-loop protection valve. The APU module structure eliminates the regeneration cylinder, which is more simple, reliable and reasonable, and makes the pipeline arrangement cleaner.

10.Ф430mm large friction clutch, large transmission torque, high transmission efficiency.

11. Weichai WEVB exhaust brake system, while ensuring safety, reduces the wear of tires and brake pads, and reduces the use cost of vehicles.

12. CUMMINS JACOB exhaust brake system:

(1) The weight of JAC system is only more than 20 kg, which can increase the freight weight by more than 300 kg while reducing the weight of the whole vehicle.

(2) JAC lifetime maintenance free, no maintenance cost, can improve operation efficiency, increase user revenue.

(3) JAC braking system can reduce the number of braking, prolong the life of brake pads, reduce the expense caused by replacement of brake pads.

(4) Up to 326 horsepower braking power can be provided in the downhill process, as well as seven 51km/h downhill gears, which is not only safer, but also greatly improved transportation efficiency.

13. Three kinds of air filters, including Freiga air filter, oil bath air filter and desert air filter, are available to extend engine life and reduce maintenance rate.

14. Enhancement of multi-leaf spring + four horse bolts, strong rigidity, stronger bearing capacity, easy to conquer all kinds of road conditions.

15. Reinforced rim, thickness increased from 14mm to 16mm, steel rim increased from 8.5 inches to 9.0 inches, bearing capacity further increased.

16. Widened variable cross section brake shoe, good heat dissipation, high braking performance, improve the service life of the friction plate, make the brake more smooth and stable.

17. With Φ120 cylinder diameter steering gear, the steering power is improved by 24%, and the working condition adaptability is improved; Reduce the pressure of steering system, effectively reduce the failure rate of components.

18. The maximum ground clearance of the protective grating is 636mm, and the thickness of the protective grating is changed from 3mm to 6mm to meet the customer's requirements to the greatest extent.

19. The rear light protection grating is added to improve the adaptability of complex working conditions, effectively protect the rear light and reduce the damage rate of the rear light.
