Howo T7H Heavy Truck Tractor

• With the rapid development of domestic and foreign heavy truck product technology, truck users have higher and higher requirements for trucks, and to implement the concept of maximizing customer value, China National Heavy Duty Truck, in collaboration with first-class international suppliers, designed and developed important parts according to international assembly design standards, and took a new road of international technical cooperation. Based on the HOWO-A7, the reliability, economy, and technical indexes of the HOWO T7H have reached an excellent level by matching the MAN engine, single-stage reduction axle, and related assemblies and parts. The whole vehicle matching design focuses on the reliability, economy, safety, and environmental adaptability indexes of the product. The market positioning is the upgraded Chinese heavy truck.

Cab

• The cab is designed with low wind resistance and sufficient space. The center console is relatively retro, and the interior design of the T7H is more traditional. AMT shift operation can make the driver stop shifting gears frequently. The auxiliary safety systems such as lane departure and forward collision warning will further enhance the active safety coefficient of the vehicle. It is the only cab in China that meets the most stringent Swedish crash regulations, which have higher indicators than European standards. The front of the vehicle is very close to the center net, and from a distance looks unusually oppressive, sharp headlights and the unique center net organic articulation, make the front sharp side leakage. HOWO T7H Heavy Duty Truck in the handling, although the whole vehicle reached 15.5 tons, the change of direction feels light, the rotation range to fit the expected, girls can also be easily managed. Sinotruk howo T7H cab follows the HOWO-A7 cab that won the “2011 China Patent Design Excellence Award”, which is unique and powerful in appearance design. The highway vehicle adopts a large span with fewer leaf springs and four airbags cab air suspension to let Chinese users enjoy the driving pleasure of the most advanced international heavy truck. With the active and passive safety of the world’s top heavy trucks, the cab collision index is designed according to Swedish standards, and the steering column can deform and absorb energy in a collision; the cab is divided into three types of standard, upgraded and deluxe versions, all of which are highly humanized, allowing Chinese customers to enjoy the comfort of safe driving in line with Europe. The cab is designed with low wind resistance, which is calibrated by a strict wind tunnel test. Howo T7H Heavy Duty Truck tractor, the wind resistance coefficient is only 0.55 under the standard load of 55T plain road at 90mph.

Engine

• T7H series products are equipped with the world’s top MAN engine localization product MC11, an engine displacement of 10.518L, with advanced structure, low speed and high torque, high reliability, low failure rate, cost-effective great advantages, the maximum power reached the national 430PS (national 440PS). cast iron material for the first time in China to ensure that the engine will not be deformed for 1 million kilometers. The main bearings and connecting rods of the engine adopt the world’s most advanced up-breaking process to achieve high-precision positioning, which helps reduce the wear of the shaft tiles and improve their life. The use of the rising break technology eliminates the need for a crankcase in the traditional sense and reduces the weight of the engine. The oil supply system of the engine adopts BOSCH high-pressure common rail form, using Mobil Black King XHP Super 10W-40 special diesel engine, the first engine oil change mileage for T7H road vehicles is 60,000 km. the classic MC11 cylinder block pickup – water channel, oil channel, intake manifold design to eliminate water leakage between the cylinder block and cylinder head, oil leakage, and intake manifold leakage. The cylinder block and cylinder head are designed with separate water and oil passages. The MC11 engine has a B10 life of 1.5 million km, which is the international advanced level. The engine has a very wide low fuel consumption and high torque range, so the engine can be in the low fuel consumption range from low speed to high speed, effectively reducing fuel consumption. The lowest specific fuel consumption is 186g/KW-h, which is 10g lower than the current domestic conventional engine, i.e. more than 5% lower.

Transmission

• The transmission adopts the mature China National Heavy Duty Truck transmission with 12 gears, and the power continuity and explosive power are quite outstanding. Through the high level tuning of HOWOT7H dump truck, the engine and transmission can give full play to the best condition. According to the engine speed, the highest gear ratio of the transmission, the speed ratio of the rear axle and the type of wheels, it can be derived from the speed calculator of the truck house that the speed of the vehicle can reach 85-92km/h in the economic speed range of 1200-1300rpm, which is very suitable for the fast transportation of tractor trucks.

Drive Axle

• The MCY13(Q) axle matched with T7H series products comes from German MAN technology, the main passive bevel gear is an Oerlikon system, the transmission efficiency reaches 98%, optional inter-wheel differential lock, wheel bearing unit is provided by SKF, which is the world’s leading rolling bearing industry. MCY13Q axle is used in long-distance transport vehicle maintenance and oil change interval up to 100,000 km (no first warranty).

Frame and Suspension

• In terms of axle and suspension, the front axle adopts HR7 axle. The front and rear suspensions are designed with fewer leaf springs, which reduces the number of leaf springs and increases the mass of individual leaf springs, ensuring good load-bearing performance while reducing weight. The rear axle adopts MCY11 axle with automatic adjusting arm, the rear axle suspension part adopts airbag suspension with good vibration filtering performance, the rear axle speed ratio is 3.36. The rear axle is equipped with V-type thrust rod, which can effectively prevent the rear axle displacement and ensure the stability of the body during driving. In order to reduce the weight of the whole vehicle, the crossbeam part adopts the ultra-lightweight overall stamping process. t7h can tow up to 30t, it has the ability to prevent the idling of the drive wheels when the vehicle is driving on the slippery road such as snow, so that the vehicle can start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system can ensure smooth acceleration performance and prevent the vehicle from moving sideways or drifting due to drive wheel slippage.
