Description

Technical Field

[0001] The present application relates to the technical field of tire testing, and in particular to a tire loading system. Background Art

[0002] A tire loading device is a device that applies a load to the load-bearing contact surface of an inflatable tire. Currently, the main application of tire loading devices is for tire factories to integrate them into high-speed endurance testing machines. The drum at the output end of the testing machine presses against the tire tread, applying radial load and rolling resistance to the tire. It also provides a drive speed to assess the tire's durability and high-speed rotation performance. The characteristics of the tire loading device on a high-speed endurance testing machine determine that it can only provide radial load to the tire. When it is necessary to assess the strength of the vehicle's suspension and frame structures under braking and sharp cornering conditions, the above-mentioned loading device cannot provide tangential force on the tire circumference and lateral force parallel to the tire axis, and its application is quite limited.

[0003] Then, some special models have high requirements for chassis suspension and frame strength due to their large curb weight and complex driving conditions. However, there is currently no special tire loading test equipment. The frame and suspension strength when the chassis makes sharp turns, skids, and brakes smoothly is assessed directly through chassis sports car tests. There is no indoor test assessment equipment, and the assessment process is complicated and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid understanding of the present invention and does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are merely intended to describe exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms, and should not be construed as being limited to the embodiments described herein.

[0026] like Figure 1 As shown, Figure 1 A structural diagram of a loading system is provided for an embodiment of the present application; a tire loading system, the loading system comprising a working platform 100 and a connecting assembly 200, wherein:

[0027] like Figure 1 As shown, the work platform 100 is movably arranged, and a work surface for carrying tires is provided on the work platform 100, so that the tires move synchronously with the work platform 100. In the assessment area, the work platform 100 is movably configured, and the displacement direction of the work platform 100 includes a different direction compared to the tires, so that when the tires are carried by the work platform 100, the friction between the tires and the work surface on the work platform 100 applies a load in a set direction to the tires.

[0028] like Figure 1 、 Figure 2 as well as Figure 3 As shown, Figure 2 Provides a front view of the loading system for the embodiment of the present application, Figure 3 A side view of the loading system is provided for an embodiment of the present application; the connecting component 200 is fixedly connected to the working platform 100, and one end of the connecting component 200 is used to connect to the power source to drive the working platform 100 to move in the test direction. The connecting component 200 is fixedly connected to the working platform 100 and serves as the connecting component 200 between the power source and the working platform 100, stably transmitting the force output by the power source to the working platform 100 to output a load in a set direction to the tire.

[0029] In an optional embodiment, the working principle of the loading system in the present application is as follows: the loading system includes a working platform 100 and a connecting assembly 200, the working platform 100 is movably arranged, and a working surface for carrying tires is provided on the working platform 100, so that the tires move synchronously with the working platform 100, and the connecting assembly 200 is fixedly connected to the working platform 100, and one end of the connecting assembly 200 is used to connect to a power source to drive the working platform 100 to move in a test direction. When the tire, suspension and partial frame are tested as a whole, the tire is arranged on the working platform 100 with the partial frame, and the connecting assembly 200 is connected to the power source. The power output by the power source is transmitted to the working platform 100 through the connecting component 200. The working platform 100 contacts the tires and outputs the forces in different directions to the tires, and finally transmits the forces to the suspension, frame and other parts connected to the tires, thereby realizing the ability of the vehicle to simulate and assess the strength of the suspension and frame structural components under braking conditions and sharp cornering conditions by loading tests in different directions. The system has strong applicability. For special models with large curb weight and complex driving conditions, when assessing indicators such as chassis side slip in sharp turns and frame and suspension strength under smooth braking conditions, the loading system can be used to conduct tests indoors directly, thereby improving assessment efficiency, avoiding the risks of sports car tests, reducing test costs and improving safety.

[0030] like Figure 1 As shown, in an optional embodiment, a plurality of mounting positions 101 are provided on the working platform 100, and the connecting component 200 is detachably connected to the mounting position 101, and when the connecting component 200 is set on different mounting positions 101 in different directions, the working platform 100 can be displaced in the length direction or the width direction.

[0031] It should be noted that the working platform 100 as a whole does not deflect. In order to maintain the loading system to apply multi-directional loads to the tire for testing, multiple installation positions 101 are arranged on the working platform 100 so that the connecting component 200 can be selectively fixedly installed on different installation positions 101 so that the working platform 100 can be driven by the connecting components 200 at different positions and the power source to perform loading tests on the tire in the target direction in different directions, thereby controlling costs while improving detection reliability and applicability.

[0032] like Figure 1 、 Figure 2 as well as Figure 3 As shown, in an optional embodiment, the loading system further includes a restraint platform 300, which is disposed at the lower portion of the working platform 100, and a plurality of restraint members 301 are provided on the restraint platform 300, and the restraint members 301 are blocked to the side of the working platform 100 and have a working gap between them and the working platform 100.

[0033] The restraint platform 300 is arranged relatively under the working platform 100, and a plurality of restraint members 301 for blocking the side of the working platform 100 are set on the restraint platform 300, so that the working platform 100 can move back and forth normally in the set direction and be blocked by the restraint member 301 in the restraint direction. The restraint member 301 keeps the working platform 100 displaced in the set area and forms a restraint protection for the working platform 100 to avoid the working platform 100 falling off due to misoperation, and a working gap is preset between the working platform 100 and the restraint member 301. On the premise of ensuring that the working platform 100 is restrained and protected, friction and impact caused by contact between the working platform 100 and the restraint member 301 are avoided to maintain working stability.

[0034] like Figure 1 、 Figure 2 as well as Figure 3 As shown, in an optional embodiment, the restraint member 301 is movably provided on the restraint platform 300 and can be moved along the length direction or width direction of the working platform 100 to adjust the size of the working gap.

[0035] The movable setting of the restraint member 301 allows the restraint member 301 to be adjusted in displacement relative to the working platform 100, thereby changing the size of the working gap, so as to facilitate adjustment of the restraint member 301's restriction on the displacement of the working platform 100, and has strong operability.

[0036] like Figure 1 、 Figure 2 as well as Figure 3 As shown, in an optional embodiment, the restraint member 301 is rotatably provided on the restraint platform 300 so that the restraint member 301 is blocked in the length direction or the width direction of the working platform 100 .

[0037] That is to say, the rotation of the restraint 301 on the restraint platform 300 allows the restraint 301 to be rotated to different positions to perform corresponding constraints on the working platform 100. Since the working platform 100 has different displacement working directions, the working platform 100 is correspondingly constrained in different displacement working directions through different positions of the restraint 301. That is to say, when the restraint 301 is blocked in the length direction or width direction of the working platform 100, the working platform 100 can correspondingly move in the width direction or length direction, and the switching of the restraint 301 is fast, convenient, and more reliable.

[0038] like Figure 1 、 Figure 2 as well as Figure 3As shown, in an optional embodiment, a strip hole 302 is provided on the restraint member 301, and a fixing bolt 303 extending into the strip hole 302 is provided on the restraint platform 300, so that the restraint member 301 moves along the extension direction of the strip hole 302, or rotates around the fixing bolt 303.

[0039] When it is necessary to adjust the working gap between the restraint 301 and the working platform 100, the fixing bolt 303 is loosened to a certain extent, the restraint 301 is adjusted for translation, and the fixing bolt 303 is locked again to complete the adjustment control of the restraint 301. When it is necessary to rotate the restraint 301, the fixing bolt 303 is loosened to a certain extent, the restraint 301 is adjusted for rotation, and the fixing bolt 303 is locked again to complete the rotation operation of the restraint 301.

[0040] The whole process is quick and easy to operate, and the restraint member 301 can be L-shaped, so that the restraint member 301 can be connected to the restraint platform 300 and can also extend to the height of the working platform 100 to restrain the working platform 100.

[0041] like Figure 1 、 Figure 2 as well as Figure 3 As shown, in an optional embodiment, the connecting assembly 200 includes a base 201 and a connecting head 202, the base 201 is fixedly connected to the working platform 100, one end of the connecting head 202 is rotatably connected to the base 201, and the other end is used to connect to a power source.

[0042] The base 201 is stably fixed on the working platform 100, and the power source outputs power to the connecting assembly 200 only after the tires and related components are arranged on the working platform 100 to prevent the working platform 100 from overturning. It should be noted that the connecting head 202 can rotate to a certain extent relative to the base 201, so as to eliminate the connection deviation during the power output process of the power source through the relative rotation between the connecting head 202 and the base 201, thereby maintaining reliable power output while reducing the assembly accuracy requirements.

[0043] like Figure 1 、 Figure 2 as well as Figure 3 As shown, in an optional embodiment, a slide 203 is provided between the connecting head 202 and the base 201, a slide groove 204 is provided on the base 201, and the slide 203 is connected to the slide groove 204 through a locking member so that the height of the connecting head 202 on the base 201 can be adjusted.

[0044] like Figure 1 、 Figure 2 as well as Figure 3As shown, under the premise that the connecting head 202 can be rotated and adapted, the setting of the slide 203 further enables the connecting head 202 to be fixed at different height positions of the base 201, thereby improving the applicability of the connecting head 202 within a height range.

[0045] like Figure 2 as well as Figure 3 As shown, in an optional embodiment, a plurality of support members 401 are provided under the working platform 100, and the support member 401 has a rolling portion 402 that rolls in contact with the working platform 100. The support member 401 maintains uniform support for the working platform 100, and reduces the friction between the working platform 100 and the working platform 100 through rolling contact between the rolling portion 402 and the support member 401, thereby facilitating the displacement of the working platform 100 and reducing wear.

[0046] In actual configuration, the rolling portion 402 may be a universal ball.

[0047] like Figure 1 、 Figure 2 as well as Figure 3 As shown, in an optional embodiment, the work platform 100 is provided with an anti-skid plate 102, and the anti-skid plate 102 is provided with an anti-skid groove 103. The anti-skid plate 102 can be made of a rubber plate to increase the friction between the tire and the anti-skid plate 102, and can be replaced regularly compared to the work platform 100. The anti-skid plate 102 is fixedly installed on the work platform 100 by multiple fixings, and the anti-skid groove 103 is further provided on the anti-skid plate 102. There are multiple anti-skid grooves 103, which are crisscrossed, so that the ridges on the tire can be embedded in the anti-skid grooves 103, further increasing the reliability of the contact between the tire and the anti-skid plate 102 and improving the accuracy of the test results.
