The sun gear and ring gear of the auxiliary box are floating to ensure even loading of the planetary mechanism. The application of the planetary mechanism of the auxiliary box and the rigid support of the output shaft’s large-span moment bearing ensure the support rigidity of the output shaft, which greatly increases the life of the auxiliary box gear and effectively solves the shortcomings of the low life of the auxiliary box of other products.
The mesh sleeve and the corresponding gear spline hole are designed with large chamfers. At the same time, due to the floating of the main shaft and main shaft gear, it can play a certain role in positioning and synchronization. The use of the mesh sleeve reduces the failure rate of the main box.
The self-locking device of the operating mechanism traditionally uses a steel ball self-locking structure, which is easy to wear. The transmission adopts a sector-shaped self-locking block and a self-locking pin shaft for self-locking, and uses a sector-shaped self-locking block and a housing to limit the position.
Interlocking is achieved by using an interlocking fork. When in a certain gear neutral position, only the shift block of the gear is aligned with the groove of the interlock fork, and the shift block on the other shift fork shaft is just blocked by the inner wall of the interlock fork. , Is locked in the neutral position, so as to achieve interlocking, the interlocking effect is good.
Structurally, to ensure that the reverse gear is engaged, it is necessary to overcome the greater spring force and the spring force of the high and low gear positioning ring to prevent accidental engagement of the reverse gear.
When the interlocking fork moves with the shift shaft to select the gear, it drives the spherical sliding column of the double H valve to realize the conversion of high and low gears.The adopted double H valve of the new structure effectively solves the defect of high leakage failure rate of the double H valve of other products.
The HOWO transmission can be found in various HOWO truck models, including:
These are just a few examples of the types of HOWO trucks that utilize HOWO transmissions. It’s important to note that the specific transmission models may vary depending on the truck model, engine configuration, and other factors. We will determine your transmission model based on your truck model.
