5. Operation is convenient; audio system, switches, gear shifting and hand brake handle are all easy to access.

II. Engine

 

HOKA adopts the 4th generation wide cylinder Styer series engine which has rigid body and longer service life and is more reliable than similar homemade engines. International advanced intelligent high pressure common rail electric injection system, with genuine Germany auxiliary parts, can intelligently control the engine according to different road conditions and always ensure optimal engine running.
Featuring low revs, big torque, strong power, good noise and emission control technology, it can bring significant fuel economy.
Germany WABOCO dual cylinder air compressor has large displacement and low exhaust temperature, and features timely supplement of compressed air, which greatly improves engine reliability and brake safety.
MANN HUMMEL fuel filter fully guarantees filtration quality and efficiency, prolongs the service life and reduces cost.
D10 series engine, 10L displacement, 270~400hp, low revs and big torque, lowest fuel consumption 192g/kw•h.
D12 series engine, 12L displacement, 340~420hp, low revs and big torque, lowest fuel consumption 192g/kw•h.

 

III. Transmission

 

 

Transmission
HOKA truck is equipped with SINOTRUCK HW series transmission. The main box adopts double intermediate shaft structure, and the auxiliary box adopts planetary mechanism, which greatly improves the reliability of the assembly. It also features wide range of gear ratio, big first gear ratio, heavy load start, and strong power for climbing, which lead to much superior performance.

Aluminum alloy housing transmission
All the HW 10-gear, 12-gear, and 16-gear transmissions can be mounted with aluminum alloy housing.
Compared with steel housing transmission of the same model, its weight reduces 90kg.
Through long term road test, the product is mature, safe and reliable.
It is used as standard parts for tractor truck and optional parts for other highway transport trucks.

 

IV. High Strength Frame

 

Frame assembly

 

Tractor truck adopts MAN technology frame. The new design of frame assembly takes TG series frame as reference: the front end of the longitudinal beam is mounted with reinforced one-piece front overhang bracket and the horizontal beam, which greatly improves the rigidity of the frame, and improves the reliability of engine and cab suspension mechanism. The frame structure is optimized: large span horizontal beam connecting plate and partial reinforcement structure provides more evenly stress distribution; standard orifice position is favorable to the allocation and connection of various assemblies.
The trapezoid frame, which is wide in the front and narrow at the rear part, is suitable for multiple kinds of engines and can improve the vehicle’s stability. The rear part is 850mm wide, which is very convenient for modification. The frame wing is widened to 90mm and adopts high strength steel.
Single layer MAN frame for tractor truck:
(8+4)×300×90 for van truck (Version 12) and Version 5
(8+7)×300×90 for mixer truck (excl. B42)
(8+5)×300×80 for dump truck (Version 1)
(8+8)×300×80 for reinforced dump truck
(8+8)×300×90 for B42
