Howo A7 Gearbox Parts

Description of Howo A7 Gearbox Parts

The gearbox of the Howo a7 Tractor Truck is an electric, automatic transmission at 16 gears, just like a highly skilled driver with higher fuel utilization in a truck. The working principle and structure of AMT are completely different from the AT of a sedan. AT for cars is the mode of driving hydraulic oil by turbine and hydraulic oil again driving mechanical device. The efficiency loss of oil drive is large, so 100 kilometers generally consumes 1-2 liters more fuel than the manual box.

The Howo A7 transmission is an automated transmission system that uses electronics and hydraulics to control the gear shifts and clutch operation. The Howo A7 transmission system uses a combination of components such as electronic control units, sensors, solenoids, clutches, and gears to ensure smooth and efficient power transmission. Here’s how the Howo A7 transmission system works:

  1. Input Shaft: The engine power is transferred to the transmission through the input shaft. The input shaft rotates along with the engine and provides the drivetrain with the power to move.
  2. Clutch System: The Howo A7 transmission system uses a dry clutch system to connect and disconnect the engine from the transmission. The clutch allows the driver to shift gears and control the drivetrain’s speed without stopping the engine.
  3. Electronic Control Units (ECU): The Howo A7 transmission system uses an ECU to manage and control the transmission’s operation. The ECU receives input signals from various sensors located throughout the vehicle, including the throttle position sensor, brake pedal sensor, speed sensors, and others. Based on these input signals, the ECU adjusts the gear shift schedule, clutch engagement, and other operations to optimize performance and fuel efficiency.
  4. Gearbox: The gearbox is responsible for changing the gears to match the driving conditions and engine load. The gear selector mechanism in the gearbox is hydraulically controlled and activated by the ECU. The gearbox has multiple gears, which are selected according to the vehicle speed and load.
  5. Output Shaft: As the gearbox changes gears, the output shaft turns at different speeds, providing the drivetrain with varying amounts of power to move the vehicle.
  • The Howo A7 transmission system provides a smooth and efficient power transmission to the drivetrain, allowing for optimal performance, fuel efficiency, and driving experience.

Replacing Howo A7 transmission parts requires specialized skills and tools and some mechanical knowledge. The following are general steps:

  1. Identify the gearbox component to be replaced and prepare the appropriate tools.
  2. Raise the vehicle to a height that allows easy access to the transmission. A jack and stands may be required.
  3. Drain the transmission fluid into a container for storage. Make sure you dispose of the old oil properly to protect the environment.
  4. Remove the gearbox housing, taking care not to disturb any other parts. You may need to refer to the Howo A7 transmission service manual to find the required steps.
  5. Remove the damaged parts one by one. You can use the appropriate tools such as wrenches, torque wrenches, plum wrenches, etc.
  6. Make sure you clearly understand how to install the new parts. Be careful when installing new parts to ensure that all details are correct.
  7. Install new parts. Follow the manufacturer’s instructions for proper installation of each new part.
  8. Open the transmission fluid spigot and pour in the correct amount of transmission fluid. Use a fluid with the correct specifications.
  9. Start the vehicle and test the transmission.

Note that it is important to read and follow the manufacturer’s guidelines and warnings before performing any service operations.
