Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a testing fixture for automobile steering wheel angle and torque. Background Technology

[0002] A steering parameter tester is a steering performance testing and inspection instrument suitable for testing the steering performance of automotive steering wheels. It can measure the free turn angle, stationary steering force, and steering wheel torque of the steering wheel, and is widely used in vehicle research and development and vehicle testing.

[0003] In the existing technology, the gauge is fixed to the circular steering wheel by the jaws at the triangular part. The position of the three jaws needs to be adjusted according to the different radii of the steering wheel to be measured. However, the three jaws in the existing equipment cannot be adjusted uniformly. They need to be adjusted in length sequentially, which cannot guarantee that the adjustment of the two jaws is consistent. At the same time, the operation is cumbersome and inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of the existing technology, which has three grippers that cannot be adjusted uniformly and require sequential length adjustment, making it impossible to ensure that the adjustment of the two grippers is consistent. At the same time, the operation is cumbersome and inconvenient to use. Therefore, this invention proposes a car steering wheel angle and torque detection fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing fixture for measuring the steering wheel angle and torque of an automobile, comprising an automobile steering parameter tester, and further comprising:

[0007] Rotation;

[0008] The vehicle steering parameter tester has three connecting rods fixed to its surface, and the rotating ring is fixed to the side end of the three connecting rods. The rotating ring is used to drive the vehicle steering parameter tester to test the steering wheel.

[0009] The vehicle steering parameter tester has three sets of clamping components. The lower side of the tester has three inverted U-shaped frames. The three sets of clamping components are respectively located in the three inverted U-shaped frames to fix the vehicle steering parameter tester to the surface of the steering wheel.

[0010] Three sets of adjustment components are respectively located between the vehicle steering parameter tester and the three inverted U-shaped frames to adjust the spacing between the three inverted U-shaped frames;

[0011] And a drive component used in conjunction with the three sets of adjustment components, the drive component being used to drive the three sets of adjustment components to move synchronously.

[0012] In one possible design, each set of adjustment components includes a first groove formed at the bottom of the vehicle steering parameter tester, a threaded block sliding in the first groove, an adjusting screw rotating in the first groove, the threaded block being threadedly connected to the surface of the adjusting screw, an extension rod being fixed to the bottom end of the threaded block, and the inverted U-shaped bracket being fixed to the side end of the extension rod.

[0013] In one possible design, the drive assembly includes a second groove within an automotive steering parameter tester. Three adjusting screws extend inwardly into the second groove, and each of the three adjusting screws has a first bevel gear fixed to its surface. A rotating shaft rotates within the second groove, and a second bevel gear meshing with the three first bevel gears is fixed to its surface. A third groove is provided within the automotive steering parameter tester, and the rotating shaft extends upwardly into the third groove. A worm gear is fixed to the surface of the rotating shaft, and a worm meshing with the worm gear rotates within the third groove. The worm extends outwardly through the surface of the automotive steering parameter tester, and a handle is fixed to the side end of the worm.

[0014] In one possible design, each clamping assembly includes a clamping plate that slides within an inverted U-shaped frame, the inverted U-shaped frame being internally threaded with a bolt that rotates at the side end of the clamping plate.

[0015] In one possible design, anti-slip pads are provided on the sides of all three clamps.

[0016] In one possible design, the surface of the swivel is fixed with an anti-slip sleeve.

[0017] In this application, turning the handle drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the shaft to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the three first bevel gears to rotate synchronously, which in turn drives the three first bevel gears to rotate synchronously, which in turn drives the three adjusting screws to rotate synchronously, which in turn drives the three threaded blocks to move synchronously, which in turn drives the three sets of clamping components to move synchronously, so that the three inverted U-shaped frames move the same distance, making it convenient to place them on the steering wheels to be tested with different radii;

[0018] Insert the U-shaped bracket into the steering wheel, and then tighten the bolts in sequence to move the clamping plate. The clamping plate, together with the side wall of the U-shaped bracket, clamps and fixes the car steering parameter tester to the surface of the steering wheel.

[0019] Beneficial effects

[0020] In this utility model, the automobile steering wheel angle and torque detection fixture can achieve the effect of quickly adjusting the distance between the three sets of clamping components through three sets of adjustment components;

[0021] In this utility model, the automobile steering wheel angle and torque detection fixture can achieve the effect of synchronously driving three sets of adjustments to move through the drive component, so that the three sets of clamping components can move synchronously.

[0022] In this invention, a rotating ring drive tester is designed for testing, which simplifies the operation process and improves the testing efficiency. The use of a precision thread adjustment mechanism and synchronous drive components ensures the accuracy of the test results. The design of three sets of clamping components and adjustment components makes the test fixture applicable to steering wheels of different sizes, improving the versatility and practicality of the equipment.

The tool mainly includes a car steering parameter tester 1, a rotating ring 2, three sets of clamping components, three sets of adjustment components, and a drive component.

[0032] Automotive steering parameter tester 1: As the core component for testing, it has three connecting rods 4 fixed on its surface. The side ends of these connecting rods 4 are fixed with rotating rings 2. The surface of the rotating rings 2 is equipped with anti-slip sleeves 3 to enhance grip stability. By rotating the rotating rings 2, the tester can be driven to test the steering wheel.

[0033] To accommodate steering wheels of different sizes, an adjustment assembly is provided between the tester 1 and the inverted U-shaped frame 6. Each adjustment assembly includes a first groove 10 formed at the bottom of the tester 1, in which a threaded block 12 slides. The threaded block 12 is threadedly connected to the adjusting screw 11. When the adjusting screw 11 rotates, the threaded block 12 moves along its axial direction, causing the extension rod 5 fixed to the bottom of the threaded block 12 and the inverted U-shaped frame 6 to move, thereby adjusting the spacing between the three inverted U-shaped frames 6.

[0034] To achieve synchronous movement of the three sets of adjustment components, a drive assembly was designed. The drive assembly includes a second groove 14 and a third groove 17 formed within the testing instrument 1. Three adjusting screws 11 all extend movably into the second groove 14, and a first bevel gear 13 is fixed thereon. A rotating shaft 15 rotates within the second groove 14, and a second bevel gear 16, meshing with the three first bevel gears 13, is fixed on the shaft 15, achieving synchronous transmission. The rotating shaft 15 continues upward, extending into the third groove 17, and a worm gear 19 is fixed thereon. A worm 18, meshing with the worm gear 19, rotates within the third groove 17. The worm 18 extends outward through the surface of the testing instrument 1, and a handle 7 is fixed to its side end. By rotating the handle 7, the worm 18 is driven to rotate, thereby driving the worm gear 19, the rotating shaft 15, the second bevel gear 16, and the first bevel gear 13 to rotate, achieving synchronous adjustment of the three sets of adjustment components.
