Description

Technical Field

[0001] This utility model belongs to the field of output shaft swing arm technology, and relates to a combined output shaft swing arm. Background Technology

[0002] As a core component of the automotive steering system, steering gears come in a variety of types, including electro-hydraulic steering gears (EHPS), electric power steering (EPS), and hydraulic steering gears (HPS). Before a steering gear is officially launched on the market, it needs to undergo comprehensive and rigorous performance evaluation and reliability testing on a test bench to ensure that it meets the various performance indicators and safety requirements of the vehicle during actual driving.

[0003] Currently, in the field of steering gear bench testing, a specific connection method is commonly used, such as... Figure 3 As shown, the steering gear assembly is securely fixed to the test bench, ensuring a tight connection between the steering gear input shaft and the input end of the test bench. Simultaneously, the steering gear output shaft is connected to the loading end of the test bench via the output shaft swing arm 01. This simulates the steering load faced by a vehicle under actual operating conditions, thereby more realistically evaluating the performance and reliability of the steering gear under different load conditions.

[0004] However, in actual steering gear bench testing, the output shaft control arm 01 needs to be matched accordingly to meet the testing requirements of different types of steering gears. But the currently used output shaft control arm 01, such as... Figure 1 He Ru Figure 2 As shown, the design of the output shaft control arm is based on the steering gear spline parameters, which increases the difficulty of machining the output shaft control arm. This not only increases the complexity of manufacturing but also significantly extends the manufacturing cycle. Furthermore, due to its heavy weight, disassembling the output shaft control arm during testing is time-consuming and labor-intensive, severely impacting testing efficiency and prolonging the product development cycle.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings:

[0037] Example 1

[0038] This utility model provides a combined output shaft swing arm, such as Figure 6 As shown, the device includes a spline sleeve 1 and a rocker arm 2. One end of the rocker arm 2 has a through hole, and the spline sleeve 1 is disposed within the through hole. A countersunk hole 3 is provided on the side wall of the rocker arm 2. A connector 4 passes through the countersunk hole 3 to fix the spline sleeve 1 within the through hole. Figure 4 As shown.

[0039] Specifically, the combined output shaft connecting rocker arm consists of a spline sleeve 1 and a rocker arm 2, the structure of which is as follows: Figure 7 As shown, the structure of rocker arm 2 is as follows: Figure 8 As shown, when the test piece is a different type of steering gear, the spline sleeve 1 is replaced according to the steering gear type, and then it is installed with the rocker arm 2. It should be noted that the rocker arm 2 is a universal component, eliminating the need for frequent replacements due to differences in steering gear types, thus simplifying the assembly process. Compared to an integrated output shaft rocker arm, as... Figure 2 As shown, this avoids the cumbersome operation and high cost of replacing the entire swing arm due to changes in sample type, thus reducing production costs and improving testing efficiency.

[0040] The spline sleeve 1 has a first spline inside, the spline parameters of which are adapted to the spline parameters of the steering gear output shaft. The spline sleeve 1 has multiple second splines outside, the shapes of which are adapted to the through holes.

[0041] The spline sleeve 1 has a first spline inside, which ensures that the spline sleeve 1 can form a tight and stable mechanical connection with the steering gear output shaft, thereby ensuring the accuracy and stability of power transmission and effectively avoiding power loss or transmission failure caused by loose connection.

[0042] like Figure 5 As shown, multiple second splines are distributed on the outside of the spline sleeve 1. Through the interlocking and nesting of the second splines and the through holes, the spline sleeve 1 is accurately positioned and firmly installed in the through holes of the rocker arm 2. This not only enhances the overall structural strength, but also realizes stable and reliable coordinated operation between the spline sleeve 1 and the rocker arm 2, laying a solid structural foundation for power transmission in steering gear tests and practical applications.

[0043] The rocker arm 2 has a countersunk hole 3 on its side wall. The connector 4 passes through the countersunk hole 3 to fix the spline sleeve 1 in the through hole.

[0044] Specifically, after the spline sleeve 1 is installed in the through hole of the rocker arm 2, the connector 4 penetrates through the outside of the countersunk hole 3 and secures the spline sleeve 1 firmly in the through hole through a threaded connection. This not only effectively restricts the axial and radial movement of the spline sleeve 1 in the through hole, ensuring a stable position during power transmission and preventing loosening or displacement due to vibration, load changes, or other factors; but also, the countersunk hole 3 allows the head of the connector 4 to be fully embedded in the side wall of the rocker arm 2, effectively preventing the protrusion from interfering with or causing wear on surrounding components. This ensures the compactness of the connection structure and improves the reliability and safety of the overall device under complex operating conditions.

[0045] The rocker arm 2 includes a first rocker arm and a second rocker arm. The first rocker arm is fixedly installed on one side of the second rocker arm. The through hole is provided on the first rocker arm. It should be noted that the axis of the first rocker arm and the axis of the second rocker arm are not on the same straight line.

[0046] The non-collinear axis design of the first and second rocker arms effectively alters the direction and path of force transmission, avoiding force concentration issues caused by linear transmission during steering system operation and significantly improving the stability and efficiency of force transmission. It can flexibly adapt to different equipment layouts, achieving efficient power transmission within limited space. This greatly enhances the versatility and applicability of rocker arm 2 in various steering system systems. Whether in bench testing environments or vehicle assembly scenarios, its unique structural advantages ensure stable and reliable operation of the connecting rocker arm.

[0047] The second spline is a rectangular spline. The tooth profile of a rectangular spline is straight, its shape is regular, and its dimensional accuracy is easy to control. During manufacturing, it can be efficiently mass-produced, effectively reducing manufacturing costs. Furthermore, the symmetrical structure of the rectangular spline facilitates quick and accurate positioning and assembly during installation. When mating with the through hole of the rocker arm 2, it ensures that the spline sleeve 1 maintains good coaxiality in the circumferential direction, guaranteeing the stability and accuracy of power transmission. Even if slight wear occurs after long-term use, the connection performance can be restored by replacing the spline sleeve 1 with one of the appropriate specifications, meeting the requirements of different working conditions.

[0048] The connecting component 4 is a clamping bolt. Through rotational tightening, it generates a strong axial clamping force, firmly fixing the spline sleeve 1 within the through hole. This simple operation facilitates quick installation and disassembly, significantly improving assembly efficiency and maintenance convenience. Furthermore, during operation, the clamping bolt can dynamically adjust the clamping force on the spline sleeve 1 in real time, effectively compensating for loosening caused by vibration, temperature changes, and other factors, ensuring consistent stability and reliability. In addition, suitable clamping bolts can be flexibly selected according to different specifications of the spline sleeve 1 and rocker arm 2, further enhancing the applicability and economy of the combined output shaft rocker arm, providing a solid guarantee for reliable connections in steering gear testing and practical applications.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
