Howo 371 Cargo Truck 6x4 for Sale In Sudan
This howo 371 cargo truck 6x4 was purchased by a Sudan customer who has his own factory and wants to expand his business. So he's going to buy a howo 371 cargo truck 6x4.
Howo 371 cargo truck 6x4 has a reliable structure, strong bearing capacity, strong power, stable performance and high market acceptance. It meets the requirements of harsh environments such as construction sites and mining areas, and is suitable for short-distance mine earthwork construction and engineering construction.
Among the Howo 371 cargo truck 6x4 axles, the front axle is mainly used for steering and is generally called the front axle. The rear axle is mainly a drive axle, which is mainly used to reduce speed and increase torque and change the direction of power transmission.
The rear axle can be divided into a single-stage deceleration drive axle and a double-stage deceleration drive axle, of which the double-stage deceleration drive axle is further divided into a central double-stage deceleration drive axle and a central and wheel-side double-stage deceleration drive axle.

Central single-stage reduction drive axle
The central single-machine deceleration drive axle is the simplest type of drive axle structure. A pair of aligned hyperbolic helical bevel gears at the central axle package realizes speed reduction and torque increase. Its structure is simple, light in weight, and easy to assemble. In the case of less than 6, a single reduction axle is used.
For some Howo 371 cargo truck 6x4 with a large load, a large reduction ratio is required. If a single-stage reduction drive axle is used, the diameter of the driven gear must be increased, which will affect the ground clearance of the drive axle and reduce the Passability of the whole bridge. Therefore, it is necessary to use a double-machine deceleration drive axle at this time.

Central two-stage reduction drive axle
There are two main types of central double-stage reduction drive axles: one is to reserve space in the single-stage reducer.
When the traction force and speed ratio are required to be increased, a cylindrical planetary gear reduction mechanism is installed to change the original central single-stage reducer. It is a central two-stage deceleration, and its axle housing, main reducer, etc. can be interchanged; the other type is to modify the first-stage bevel gear and then install the second-stage cylindrical spur gear or helical gear to become a central two-stage drive axle .
As a derivative product, the central two-stage reduction drive axle is subject to certain restrictions, so it is generally not developed as a basic bridge type, but only used as a derivative special drive axle.

Central single-stage, wheel-side reduction drive axle
The wheel-side deceleration drive axle is composed of the central first-level deceleration and the wheel-side first-level deceleration. The current wheel side reduction drive axle can be divided into two types: conical planetary gear wheel side reduction axle and cylindrical planetary gear wheel side reduction axle.
The main difference is that the wheel side planetary gear structure is different. Due to the existence of one-stage wheel deceleration, this type of bridge reduces the torque transmitted by the half shaft, and the increased torque is directly added to the wheel head reducer.
The reduction ensures the high passability of the Howo 371 cargo truck 6x4. Compared with the single-stage axle, its structure is complex, heavy and expensive, and there is a gear transmission in the wheel side reduction shell, which will generate a lot of heat and cause the wheel hub to overheat when running for a long time.
