Pro-JAC freight car gearbox hangs high-grade and has abnormal sound; The causes of abnormal noise during gear shifting of the gearbox are as follows:
1, the driver improperly operates, starts too hard, and the hands and feet do not cooperate properly when shifting gears, resulting in great impact when driving, and the gear teeth will break or break, resulting in abnormal sound.
2. Due to the failure of the gear box mechanism, the internal bearing is damaged.
Information about the gearbox is as follows:
1, gearbox, also known as transmission, is used to change the speed and torque from the engine, and the transmission ratio of the output shaft and the input shaft can be fixed or changed step by step.
2. The gearbox consists of variable speed transmission mechanism and control mechanism. Some cars also have power output mechanisms, which are divided into stepped, stepless and comprehensive transmissions, and have the functions of reversing, interrupting power transmission and changing transmission ratio.

There is abnormal noise when the gearbox of Jianghuai freight car is in high gear.
Hello, I'm Xiao Yang, Baidu's co-teacher. I am good at auto repair, and I have been engaged in the auto repair industry for 6 years now. I am good at analyzing problems, finding problems, solving problems, and serving customers from modification to maintenance ~ very detailed ~ I received your question. Typing takes a little time (3-4 minutes). A moment, please. Please don't end the consultation. You can also provide more information so that I can serve you better.
Hello, dear, I'm glad to be of service to you. According to your description, the gearbox of Jianghuai freight car has the following abnormal noise.
Dear, there is abnormal noise when the gearbox of Jianghuai freight car hangs high-grade; The causes of abnormal gear shifting noise of gearbox are: 1, improper operation by driver, too hard start and improper hand-foot coordination during gear shifting, which leads to great impact during transmission, and the gear teeth will break or break, resulting in abnormal noise. 2. Due to the failure of the gear box mechanism, the internal bearing is damaged. The information about the gearbox is as follows: 1. Gearbox, also known as transmission, is an automobile accessory used to change the speed and torque from the engine, which can change the transmission ratio of the output shaft and the input shaft in a fixed or step-by-step way. 2. The gearbox consists of variable speed transmission mechanism and control mechanism. Some cars also have power output mechanisms, which are divided into stepped, stepless and comprehensive transmissions, and have the functions of reversing, interrupting power transmission and changing transmission ratio.

Pro shift gear 1 abnormal sound, damage to transmission housing, long-term wear and deformation of transmission housing and bearing housing holes. The noise of this kind of training is the biggest when you are engaged in low gear. With its engagement in the high gear, the noise gradually decreases and the direct gear is the smallest. 2, due to the surface fracture of individual gears, resulting in the impact in the meshing process. When this gear is engaged, there will be strong impact and vibration, which will cause abnormal sound of the transmission housing. 3. Improper assembly of the transmission, improper replacement of a gear or needle bearing and bushing in a certain gear of the transmission, and abnormal assembly clearance, resulting in poor gear engagement and abnormal noise during gear transmission. Precautions for noisy gear shifting 1. The car should come to a complete stop. 2. If there is abnormal noise, first return to neutral, release the clutch and then step on it, and then put in reverse gear. There is usually no noise. If it still appears, repeat the above operation. 3. In case there is noise in gear shifting, don't forcibly shift gears, otherwise the repair cost after gear shifting will be very expensive.
