howoTH7 4x2 540hp tractor truck with AMT, strong power

Recently, we found a HOWO TH7 4x2 tractor on the market, matched with a Sinotruk automatic transmission, with a large fuel tank, to see if the vehicle can meet the needs of express e-commerce operations and general cargo transportation.

The first condition of express e-commerce transportation is timeliness, which requires the goods to be delivered to the receiving point within the specified time, that is to say, the average speed of the vehicle must be high in order to run on the highway, and secondly, high reliability is required, which cannot be used in the expressway. There are frequent breakdowns in transit, affecting time, and excellent safety is required to further protect the driver and cargo.

First of all, let’s take a look at the power that everyone is most concerned about. This real vehicle is equipped with a Sinotruk MC13H.54-61 engine. Many careful card friends may have found that the engine suffix has a “H” word, which is It is said that this machine adopts the latest H technology platform of Sinotruk and has higher thermal efficiency. In addition, the displacement of the new MC13H platform has increased to 13.02L, which is about 0.6 liters more than the 12.419L displacement of the old MC13, and the overall performance will also be improved to a certain extent.

In terms of gearbox, this TH7 matches Sinotruk's own S-AMT16 automatic gearbox, which has been widely installed in Sinotruk's Howo, Yellow River and Shandeka products. The characteristics of this transmission can be freely switched between automatic gear and manual gear, allowing the driver to make corresponding gear adjustments according to the current working conditions.

This configuration of hydraulic retarder has been widely installed on medium and heavy truck models. In mountainous areas and long downhill conditions, it can reduce the burden on the main brake, keep it in good condition, and ensure that the vehicle is safer on long downhills. and efficient.

The truck is equipped with aluminum alloy wheels with a specification of 12R22.5, and the whole vehicle adopts disc brakes, which not only has a more sensitive braking effect, but also has better heat dissipation performance than ordinary drum brakes.

According to the tire specification, the rear axle speed ratio of 2.71, and the highest gear ratio of the gearbox is 1, it is obtained through the truck home speed calculator that when the tachometer is at 1200 rpm, the vehicle speed is 87 km/h. Combining the speed range and vehicle speed, this TH7 can achieve a higher average speed at low speed, and it also has a certain improvement in economy, which is obviously aimed at efficient logistics transportation.

In the chassis part, the front axle of the vehicle adopts 2-piece less-leaf spring suspension, the rear axle is Sinotruk MCY13JES, adopts airbag suspension, and the speed ratio is 2.71. The airbag bridge can adjust the height of the airbag to meet the high-efficiency drop and pull transportation, and at the same time, it can improve the driving comfort, reduce the impact of the road on the cargo compartment, and help protect the safety of the cargo, especially the high added value of precision instruments and electronic equipment. Products should be transported by vehicles with airbag bridges.

This HOWO TH7 tractor truck adopts a 4x2 drive form and can form a four-axle articulated train with a two-axle semi-trailer. The total weight of the vehicle and cargo is 36 tons, and it only needs to pay the high-speed toll fee required by the four-axle truck. It forms a five-axle articulated train with a three-axle semi-trailer, which meets the total mass limit of 42 tons, and the toll fee is also more advantageous than the common six-axle train. In general, if it is not mainly heavy goods and mainly takes the highway, then the 4x2 tractor will have certain advantages.
