The transmission system is to transmit the power from the engine to the driving wheels of the car to generate driving force so that the car can run at a certain speed. The transmission system is composed of clutches, transmissions, universal transmissions, final reducers, differentials and half shafts. The following is a detailed introduction to the composition of the transmission system:
1. Sinotruk Clutch
The clutch is similar to a switch, which engages or disengages the power transmission to ensure smooth shifting, and interrupts the power transmission when necessary.
Clutch products, including single plate clutches, double plate clutches and diaphragm spring clutches. Clutch models include 430, 430A, 430B, 430C, 430D, 430Z, 430ZB and 430ZC. These models are specially designed for various truck models produced by Sinotruk, such as HOWO and STEYR series. The clutch has large torque capacity, good heat dissipation performance and long service life.
2. Sinotruk Transmission
A transmission is a mechanism used to change the speed and torque from the engine. It can fix or step by step change the transmission ratio of the output shaft and input shaft to achieve speed change, torque change, direction change and interrupt power transmission.
The gearbox models include HW series, HW19710, HW19712, HW19713, HW19712T, HW19710T, HW19713T, HW25710, HW25712T, HW20716, etc. These models are designed to be widely applicable to Sinotruk heavy-duty trucks, such as HOWO and STEYR series, which are widely used in transportation in various industries. The HW series is designed with advanced technology, low fuel consumption and strong power transmission characteristics, making it more reliable and efficient. The HW series features synchronizers, decouplers and range gears for cargo transport and heavy equipment transport.
3. The universal transmission device
The universal transmission device is a device used to transmit power between two shafts whose relative positions are constantly changing during the working process. power transmission.
The gearbox models include HW series, HW19710, HW19712, HW19713, HW19712T, HW19710T, HW19713T, HW25710, HW25712T, HW20716, etc. These cardan transmission models feature advanced technology integration with synchronizers, decouplers and range gears, as well as handling high power transmission tasks with ease. These transmissions are highly reliable, efficient and low fuel consumption. The gearbox models are suitable for Sinotruk’s widely used heavy truck series, such as HOWO and STEYR series, which are widely used in various industries for transporting various goods and heavy equipment.
4. Main reducer
The main reducer is a mechanism that can change the torque and speed in the drive axle. The basic function is to increase the torque from the transmission or universal transmission, while reducing the speed and changing the direction of torque transmission.
Main gearbox models designed to suit different heavy truck makes. Gearbox models include HW series, HW18710, HW19712, HW20716, etc. These major transmission models incorporate advanced technology with synchronizers, decouplers and range gears to handle high power transmission duties with ease. These gearboxes are highly reliable, efficient and have low fuel consumption. The gearbox model is suitable for various heavy truck brands such as HOWO, STEYR, MAN, and FAW. These trucks are widely used in various industries to transport various goods and heavy equipment.
5.Differential
The car differential can make the left and right (or front and rear) drive wheels rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier.
Differential models designed to fit different heavy truck makes. Differential models include MCY13, MCY11, MCY9, etc. These differential models are equipped with advanced technology to ensure high precision and stability. They are very reliable, durable and perform well under heavy loads. These differentials also provide better traction and more precise control, ensuring a safer, more stable driving experience. The differential model is suitable for various heavy truck brands such as HOWO, STEYR, MAN, FAW, etc. These trucks are widely used in various cargo transportation, construction, mining and many other industries.
6. The half shaft
Also called the drive shaft, is the shaft that connects the differential with the drive wheels. Its role is to transmit the power of the differential to the drive wheels.
Sinotruk offers a variety of rear axle models suitable for different heavy truck brands. Available rear axle models are MCY13, MCY11, MCY9, etc. These axle models feature state-of-the-art technology ensuring high precision, stability and durability under heavy loads. They provide excellent traction for a safer and more stable driving experience. The rear axle model is suitable for various truck brands such as HOWO, STEYR, and FAW. These trucks are widely used in cargo transportation, construction and mining.
Second, the reasons for the failure of the transmission system are as follows:
- The clutch slips, and the symptoms of the fault are: difficulty in starting, weak driving, poor acceleration, and in severe cases, it will emit a burnt smell or black smoke.
Solution: replace the clutch plate.
- Abnormal sound of transmission system. The fault is manifested as: when starting, the body shakes, and there is a “crack, cluck” impact sound, and the sound is more obvious when changing the speed of the vehicle, especially when driving slowly.
Solution: Check for replacement parts.
- The transmission skips gears. The fault is manifested as: when driving in gear, the transmission automatically jumps back to neutral. Solution: Check for replacement parts.
- The clutch separation is not complete. Fault performance: frequent shifting difficulties, teeth ringing. After the gear is engaged, the vehicle will run or the engine will be turned off without lifting the clutch pedal.
Solution: Replace the release bearing.
- Vibration at start. The fault is manifested as: when starting, the clutch is not combined smoothly, which causes the body to shake.
Solution: replace the clutch.
Three, the daily maintenance tips of the transmission system:
To maintain the heavy truck transmission system, regular maintenance is essential. Here are some basic tips for maintaining your transmission system:
(1) Regularly check the transmission fluid level to ensure it is at the recommended level.
(2) Check the transmission system for any leaks or damaged parts, especially the transmission disc gasket and transmission cooler lines.
(3) Change the transmission fluid and filter at recommended intervals, or when the fluid becomes dirty or burnt.
(4) Check the gearbox bracket and replace if worn or damaged.
(5) Make sure that the gearbox does not bear an excessive load when driving, and reduce the speed when going uphill or carrying heavy loads.
By following these simple maintenance tips, you can ensure optimal performance of your transmission system and extend the life of your vehicle. Regular maintenance helps prevent breakdowns, increases safety and reduces repair costs.
In summary, Sinotruk continues to provide cutting-edge drivetrain solutions to enable its customers to achieve the best performance, reliability and safety. Looking ahead, the company will remain committed to driving innovation and sustainable growth, while continuing to be a trusted partner to customers around the world.
