Description
Technical Field
[0001] The utility model relates to the technical field of transmissions, in particular to a steering gear shaft of an automobile transmission. Background Art
[0002] The steering gear shaft of the automobile transmission is one of the key components in the automobile transmission system. It is responsible for transmitting the gear signal selected by the driver through the gear lever to the gear mechanism inside the transmission, thereby achieving the output of different speeds and torques. With the development of the automobile industry, the requirements for transmission performance are also constantly increasing, which has prompted the continuous progress and innovation of transmission steering gear shaft technology. Modern automobiles pursue higher fuel efficiency and driving comfort, which requires the transmission to provide more gear options to adapt to different driving conditions. With the popularization of automatic transmissions and semi-automatic transmissions, higher requirements are placed on the automation and response speed of the transmission. In order to improve the fuel efficiency and handling performance of the car, automobile manufacturers are constantly seeking ways to reduce the weight of the car, and the lightweight design of the transmission steering gear shaft has become a research focus.
[0003] In actual use, without proper slotting structure, components may be difficult to install correctly, resulting in complicated installation process or the need for additional adapters. Slotted structures are usually used to fix and position components, such as springs and movable columns. The lack of slotting may cause these components to be unable to be stably fixed, affecting the overall stability of the transmission. The slotted structure helps to fix the springs and provide necessary buffering effect. Without slotting, the springs may not be installed correctly, thereby weakening the ability to buffer shock and vibration. The slotting allows the movable column to move in a specific direction in response to external forces. Without slotting, the movement of the movable column may be restricted, reducing the response speed and accuracy of the transmission. If the components cannot be stably fixed by the slotted structure, more time and effort may be required to remove and reinstall the components during maintenance. Utility Model Content
