[0002] A car is a motor vehicle consisting of an engine, chassis, body and other components. Its function is to provide people with a convenient means of transportation and to drive on the road. Cars can be divided into two categories: fuel vehicles and electric vehicles. The former is powered by an internal combustion engine, while the latter is driven by batteries or fuel cells. Modern cars have many functions, such as air conditioning, airbags, anti-lock braking systems, etc.

[0003] The automobile gearbox is the core component of the transmission system, which is used to adjust the ratio between the engine output torque and the wheel speed to adapt to different driving conditions. Common gearbox types include manual gearbox and automatic gearbox. Manual gearbox requires the driver to manually operate the clutch and shift lever, while automatic gearbox automatically shifts gears through hydraulic or electronic systems. Modern cars also have advanced gearbox types such as CVT and DSG. The gearbox improves the driving comfort and fuel economy of the car by converting the engine speed and torque into appropriate vehicle speed and power.

However, the traditional way of connecting the drive shaft to the gearbox is by bolts. This fixing method will cause the bolts to loosen or even fall off after long-term use of the car, seriously affecting driving safety. Therefore, an automobile gearbox connecting shaft is proposed to solve the above problem. Utility Model Content
