Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to a connecting device for an automobile steering column. Background Art

[0002] In the automotive manufacturing industry, the steering column is the core component of the steering system. Its performance and quality are directly related to the safety and driving experience of the entire vehicle. However, during the manufacturing and testing process, the steering column faces some challenges that cannot be ignored.

[0003] First, since the steering column is usually installed in the passenger compartment, its space layout is relatively compact, which brings certain difficulties to the inspection work; before leaving the factory, due to time and cost constraints, the steering column often cannot undergo a highly simulated vehicle inspection process; this leads to the inability to fully evaluate the performance of the steering column under various complex working conditions and extreme conditions that may be encountered in actual use; this lack of sufficient inspection environment may cause potential defective products to enter the market, posing safety hazards to drivers;

[0004] Secondly, traditional steering system connection methods are prone to problems under complex working conditions and long-term use. Loose connections, performance degradation and even failures are common phenomena. The emergence of these problems is often closely related to the design, manufacturing and material selection of connectors. For example, factors such as insufficient matching accuracy of connectors, uneven tightening force or material fatigue may lead to loose connections and performance degradation. In addition, traditional connection methods usually lack sufficient length flexibility and cannot adapt to changes in requirements under different vehicle models and working conditions. This further limits the stability and reliability of the steering system and poses a potential threat to the safety of the driver.

[0005] Therefore, in order to solve these problems, it is particularly important to carry out special inspection activities on the steering column in the steering system. Utility Model Content

[0028] It should be noted that in the automotive manufacturing industry, the performance and quality of the steering column are crucial to driving safety and experience. However, the compact spatial layout and limitations of the inspection process make it difficult to fully evaluate potential problems, increasing safety risks. Traditional connection methods are prone to problems under complex working conditions, limiting the stability and reliability of the steering system. Therefore, it is particularly necessary to conduct special inspections and optimized designs of the steering column. This solution significantly improves the stability and reliability of the steering system. The device effectively solves the problems of loose connections, performance degradation, and even failures that are prone to occur in traditional connection methods under complex working conditions. At the same time, it provides a stable and reliable inspection condition for the inspection of the steering column. In addition, the device also has excellent lubrication and anti-pollution capabilities. By directly lubricating the conical mating part between the spline shaft 5 and the rotating shaft 9, friction and wear are effectively reduced, thereby further improving the service life and efficiency of the system.

[0029] Specifically, in this embodiment, the scheme mainly includes a transmission shaft tube 1, a flange stop 2 on the outer side of the transmission shaft tube 1; a connecting rod 3 provided on one side of the transmission shaft tube 1, which is screwed with a bolt and a threaded connection port, and the device can be firmly fixed on the equipment; this fixing method ensures the stability and reliability of the entire system; a groove stop 4 is provided on the outer side of the connecting rod 3, and a flange stop 2 is provided on the outer side of the transmission shaft tube 1, and the two cooperate with each other; this cooperation method of the flange stop 2 and the groove stop 4 not only provides a stable positional relationship, but also ensures that the connection between the transmission shaft tube 1 and the connecting rod 3 is both stable and precise;

[0030] In order to further enhance the stability of the connection, a locking structure is further provided between the transmission shaft tube 1 and the connecting rod 3, which further fixes the cooperation between the flange stop 2 and the groove stop 4, preventing the relative movement between the two, thereby ensuring the connection stability and reliability of the entire system;

[0031] The lubrication chamber 6 in the spline shaft 5 is an important part of the system. Lubricating oil can be added to the lubrication chamber 6 through the oil filling hole 7 on the top. After the lubricating oil enters the lubrication chamber 6, it can flow out through the oil outlet hole 8 on the outer wall of one side of the spline shaft 5 to directly lubricate the conical surface fitting part between the spline shaft 5 and the rotating shaft 9. This lubrication design effectively reduces friction and wear, thereby improving the service life and efficiency of the system.

[0032] The conical surface fit between the rotating shaft 9 and the spline shaft 5 not only provides a stable and reliable transmission mode, but also has self-locking properties; this self-locking property can prevent slippage when transmitting torque, thereby ensuring the accuracy and reliability of transmission;

[0035] In this embodiment, when the fastening bolt 15 is rotated, due to the mutual meshing of the threads, the bolt will be gradually tightened, thereby tightly connecting the drive shaft tube 1 and the connecting rod 3 together. As the fastening bolt 15 is gradually tightened, the small gap between the drive shaft tube 1 and the connecting rod 3 is gradually eliminated, ensuring a stable connection between the two. This connection method is not only stable and reliable, but also highly precise, and can effectively ensure the stability and reliability of the steering column motor clamping device during operation.

In addition, by sliding fit and adjusting the length of the connecting shaft 11, the relative position between the two shaft bodies can be flexibly adjusted, further increasing the flexibility of application.

[0048] The conical surface fit between the rotating shaft 9 and the spline shaft 5 not only provides a stable and reliable transmission mode, but also has self-locking properties, which can prevent slippage when transmitting torque, ensuring the accuracy and reliability of transmission;
