Description

Technical Field

[0001] The utility model relates to the technical field of tire testing, in particular to a novel tire endurance testing machine. Background Art

[0002] The tire endurance test is to improve the identification and evaluation level of the quality of my country's automobile tire products, improve the tire standard system, and improve the design level of tires.

[0003] In the current public technology, the tire endurance test device effectively simulates the friction between the tire and the ground during driving through the friction between the components and the tire, thereby evaluating the tire's endurance and service life. However, the traditional tire endurance test device often has certain limitations in design. Specifically, the components of the existing device that are in friction contact with the tire are mostly fixed and cannot be adjusted in angle. Testers cannot test the endurance performance of the tire tread at multiple angles according to actual needs. In fact, during driving, especially when turning, the tire will have an inclination angle and a slip angle, which will affect the wear of the tire; therefore, it is impossible to simulate the tire wear in these actual scenarios, which limits the diversity and accuracy of the test methods. Therefore, it is necessary to develop a new type of tire endurance tester. Utility Model Content

The upper and lower walls of the test bench 100 are provided with an arc-shaped arc opening 340 centered on the rotating shaft 300, a shaft gap of the cross plate 320 passes through the arc opening 340 and a friction member 330 is provided on the top, the cross plate 320 is in a "cross" shape and the middle horizontal plate is attached to the upper surface of the test bench 100, and two fixing frames 350 are provided at the bottom of the test bench 100 in front of the rotating shaft 300, and a horizontal driving rod 360 is rotatably penetrated through the side walls of the two fixing frames 350, a worm 370 is provided on the shaft of the driving rod 360 near the rotating shaft 300, and a worm wheel 380 engaging with the worm 370 is provided on the shaft of the rotating shaft 300.

[0032] Furthermore, the control component includes a transverse threaded column 130 rotatably arranged on the inner wall of the slide groove 110 through a bearing seat, and a transverse guide slide rod 140 fixedly arranged on the inner wall of the slide groove 110. The rod body of the threaded column 130 is screwed through the side wall of the movable seat 120, and the rod body of the guide slide rod 140 slides through the side wall of the movable seat 120. The left end of the threaded column 130 extends and rotates to penetrate the left side wall of the test bench 100. A hand crank 150 is arranged on the left end of the threaded column 130. After the threaded column 130 is rotated by the hand crank 150, the movable seat 120 moves left and right along the rod body of the threaded column 130 and the guide slide rod 140, thereby adjusting the distance between the tire and the friction member 330.

[0033] Furthermore, vertical legs 160 are arranged around the bottom of the test bench 100, and fixing holes 170 are arranged around the lower end of each leg 160. The device can be conveniently fixed by screws adapted to the fixing holes 170, thereby improving the stability of the device during testing.

[0034] Furthermore, the mounting plate 230 is disc-shaped, and the side wall of the mounting plate 230 is provided with mounting holes 240 at equal intervals around its own center. The mounting holes 240 are aligned with the mounting holes on the wheel hub. Suitable bolts are selected to mount the wheel hub with the tire on the mounting plate 230 for testing.

When it is necessary to drive the tire to rotate, the servo motor 260 is started to drive the driving gear 280 to rotate, and the rotating rod 220 is driven to rotate through the chain 290 and the follower gear 270, so that the mounting plate 230 drives the tire to rotate.

[0036] Furthermore, the lead angle of the worm 370 is smaller than the equivalent friction angle between the teeth of the meshing worm wheel 380. The mechanism has self-locking properties and can achieve reverse self-locking, that is, only the worm 370 can drive the worm wheel 380, but the worm wheel 380 cannot drive the worm 370, so that the friction member 330 is more stable after the position is adjusted. One end of the drive rod 360 is located on the outside of the test bench 100 and is provided with a hand crank 2 390. The hand crank 2 390 can conveniently drive the drive rod 360 to rotate, thereby driving the rotating shaft 300 to rotate through the worm 370 and the worm wheel 380, so that the connecting plate 310, the cross plate 320 and the friction member 330 rotate around the rotating shaft 300, thereby changing the angle between the friction member 330 and the tire.

[0037] In the specific use process, suitable bolts are selected to install the wheel hub with the tire on the mounting plate 230, and the tread angle of the tire is tested as needed. The driving rod 360 is driven to rotate by the hand crank 2 390, so that the rotating shaft 300 is driven to rotate by the worm 370 and the worm wheel 380, so that the connecting plate 310, the cross plate 320 and the friction member 330 rotate around the rotating shaft 300, and the angle between the friction member 330 and the tire is changed. After the threaded column 130 is driven to rotate by the hand crank 1 150, the movable seat 120 moves left and right along the rod body of the threaded column 130 and the guide slide bar 140, so as to adjust the distance between the tire and the friction member 330, so that the two are in contact. Finally, the servo motor 260 is started to drive the driving gear 280 to rotate, and the rotating rod 220 is driven to rotate by the chain 290 and the follower gear 270, so that the mounting plate 230 drives the tire to rotate, and generates friction with the friction member 330, and its endurance is tested.

[0038] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
