Features & Advantages of Sinotruk Howo Transmission

  • The main box double countershaft structure: the symmetrically arranged double countershafts balance the radial forces on the input shaft and the gears on the main shaft. The input shaft and the main shaft only bear the torque without bending deformation; the intermediate bearing is subject to bending moment reduction Small 1/2, small bending deformation, good gear meshing condition.
  • Sub-box planetary mechanism: This mechanism has the characteristics of compact structure, light weight, large transmission ratio and high efficiency. Since one sun gear meshes with 5 planetary gears at the same time, the bearing capacity is greater.

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.

When the shift fork shaft of the auxiliary box range is not in place, the interlocking plate gets into trouble under the action of the shift fork shaft, so that the main box shift fork shaft is locked in the neutral position. Then push the lock plate, so that the main box can be shifted to the fork shaft, and then connected to each other to be blocked as needed.
Self-locking structure

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 structure

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.

Reverse lock

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.

Double H valve

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 is a complex and sophisticated system that works to transfer power from the engine to the wheels of a vehicle. Here is a brief description of how it works:
  1. Power Input: The transmission receives power from the engine via the input shaft. This power is sent into the transmission in the form of rotational energy.
  2. Gear Selection: The driver selects the desired gear using the gear selector lever. The Howo Transmission typically offers a range of gears, including forward gears for different speeds and a reverse gear for backward movement.
  3. Gear Ratio: Depending on the gear selected, the transmission engages different sets of gears to achieve the desired gear ratio. This ratio determines the speed and torque output of the transmission.
  4. Clutch Engagement: In a manual transmission, the clutch pedal is depressed to disengage the engine from the transmission momentarily while shifting gears. This allows for a smooth transition between gears without causing damage to the transmission.
  5. Power Output: Once the desired gear is engaged, power is transmitted from the transmission to the wheels via the output shaft. The gear ratio selected influences the rotation speed and torque applied to the wheels.
  6. Torque Converter (Automatic Transmission): In an automatic transmission, a torque converter is used to transfer power from the engine to the transmission. It uses hydraulic fluid to transmit power and allows for smooth and seamless gear changes without the need for manual clutch engagement.
  • Overall, the Howo Transmission works by selecting the appropriate gear ratio and engaging the clutch or torque converter to transfer power from the engine to the wheels, enabling the vehicle to move at different speeds and loads.
  • The cost of a Howo Transmission can vary depending on several factors, including the specific model, availability, and seller. Therefore, it is difficult to provide an exact price without more specific information. We recommend contacting us for accurate pricing details based on your specific needs. We can provide you with up-to-date and accurate information about Howell Transmission costs.
To properly use the Howo Transmission in a truck, follow these general steps:
  1. Familiarize yourself with the gear selector: The gear selector is typically located on the floor of the truck or on the steering column. It allows you to choose the desired gear for your driving needs.
  2. Start the engine: Ensure the truck’s engine is running before attempting to engage the transmission. This can be done by turning the ignition key or pressing the start button, depending on the truck’s design.
  3. Depress the clutch pedal (for manual transmission): If your truck has a manual transmission, depress the clutch pedal with your foot to disengage the engine from the transmission. This allows for smooth gear shifting.
  4. Select appropriate gear: With the clutch pedal depressed (if applicable), move the gear selector to the desired gear. This will typically involve moving the gear lever forward or backward or selecting a specific gear number.
  5. Release the clutch pedal (for manual transmission): Slowly release the clutch pedal while gradually applying pressure to the accelerator pedal. This allows the clutch to engage and transfers power from the engine to the transmission, enabling the truck to move.
  6. Accelerate and shift gears (for manual transmission): As you accelerate, monitor the engine’s RPM (revolutions per minute) and the truck’s speed. When the engine RPM reaches the optimal range for the next gear, depress the clutch pedal again, shift to the next appropriate gear, and release the clutch pedal smoothly while continuing to apply pressure on the accelerator.
  7. Operate the gear selector (for automatic transmission): If your truck has an automatic transmission, the gear shifting is done automatically. Simply move the gear selector to “Drive” or “D” and release the brake pedal to start moving. The transmission will shift gears automatically based on speed and load conditions.
  • Remember to always follow the specific instructions provided in the truck’s user manual as the exact operation may vary depending on the model and configuration.
