Abstract: Heavy duty transmissions play an important role in the transmission system of commercial vehicles, as their quality directly affected driving comfort and handling. In order to adapt to the development trend and matching needs of high-power engines in commercial vehicles, this article analyzes the structure and characteristics of a heavy-duty transmission gear transmission, and finally summarized the common faults and cause analysis of the gearbox, The spindle floating and lubrication measures in the transmission design are proposed. This can provide a basis and reference for the diagnosis of abnormal noise faults in the gearbox and the design of the gearbox.
