Description

Technical Field

[0001] This utility model relates to auxiliary equipment for testing and inspection of automobile performance, specifically to a non-drive axle wheel end fixing fixture for automobile hub testing. Background Technology

[0002] Wheel swivel testing is a common automotive performance testing method during vehicle product development, primarily used to test overall vehicle performance such as power and fuel economy. Specifically, the wheel swivel test involves fixing the car to a wheel swivel test bench and evaluating various performance indicators by rotating the wheels. This method helps automakers understand vehicle performance, thereby optimizing design and improving driving experience and safety.

[0003] As an important vehicle performance testing device, the swivel test bench can not only easily repeat the swivel test multiple times under the same conditions, but also is less affected by external environmental factors. When used with an environmental chamber, it can simulate a variety of natural environments for testing. Therefore, the swivel test shortens the product development cycle, accelerates the launch of new products, saves product development costs, and plays an important role in improving various vehicle performances. It is increasingly favored by automobile manufacturers.

[0004] With the rapid development of the domestic public transportation and logistics industries, low-floor vehicles are increasingly praised by passengers and users for their convenience in boarding and alighting and for loading and unloading goods. However, currently, during wheel rotation tests, the vehicle frame or axles are secured on the test bench using chains or steel cables. Because of their low chassis and surrounding structure, low-floor vehicles lack reliable anchoring points or are even impossible to secure using conventional methods. This results in instability in the test vehicle, with increased shaking during acceleration and deceleration, posing a significant safety hazard. Utility Model Content

[0005] The technical problem to be solved by this utility model is that it is inconvenient to fix low-floor vehicle models during wheel rotation tests. This utility model provides a non-drive axle wheel end fixing fixture for vehicle wheel rotation tests that is simple in structure, reliable in fixing, easy to install and disassemble, and can effectively solve the problem of fixing the non-drive axle wheel end of low-floor vehicle models.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A non-drive axle wheel end fixing fixture for automobile wheel hub testing is characterized by comprising a flange plate, an intermediate connecting member, and a connecting seat, wherein the flange plate, the intermediate connecting member, and the connecting seat are fixedly connected in sequence. The flange plate is provided with a plurality of first mounting holes that match the bolt holes on the wheel rim of the test vehicle and a second mounting hole for passing through the end of the wheel axle of the test vehicle. The connecting seat includes two connecting ears arranged opposite each other. One end of the two connecting ears is fixedly connected to the intermediate connecting member, and the other end is connected by a connecting rod. A connection gap is left between the connecting rod and the intermediate connecting member.

[0008] This invention breaks away from the traditional approach of fixing vehicles to the chassis and axles in wheel swivel tests. Instead, it utilizes flange plates and tire-fixing bolts and nuts to connect to the test vehicle's wheel rims and axles. A connecting rod and connecting lug at the other end form a connecting seat for secure fixation, thus enabling the fixation of low-floor vehicles on the wheel swivel test bench. This invention features a simple overall structure, reliable fixation, and convenient installation and disassembly. It effectively solves the fixation requirements for the non-drive axle end of low-floor vehicles, providing strong support for the smooth conduct of wheel swivel tests and vehicle stability. It improves testing efficiency and the accuracy of test data, shortens the development cycle for new vehicle models, and saves testing costs.

[0009] Preferably, the flange plate is disc-shaped, and the periphery of the flange plate fits against the wheel rim of the test vehicle to facilitate a stable and reliable connection between the flange plate and the wheel rim of the test vehicle.

[0010] Preferably, the intermediate connector includes a connecting sleeve, the interior of which is hollow to avoid other components at the axle end of the test vehicle.

[0011] Preferably, the connecting sleeve is connected between the first mounting hole and the second mounting hole of the flange plate.

[0012] Preferably, the intermediate connector further includes a connecting plate, which is disposed between adjacent first mounting holes of the flange plate so as not to affect the installation of the tire bolts. The inner side of the connecting plate is connected to the connecting sleeve. One end of the connecting plate is connected to the flange plate, and the other end is connected to the connecting seat to increase structural strength and reliability.

[0013] Preferably, it further includes an intermediate connecting plate, one side of which is connected to the intermediate connecting member and the other side is connected to the connecting seat, so as to further improve the structural strength.

[0014] Preferably, the intermediate connecting plate is a circular plate, and the intermediate connecting plate is arranged parallel to the flange plate. The diameter of the intermediate connecting plate is smaller than the diameter of the flange plate, so as not to affect the operation of the tire nut installation tool and to facilitate installation.

[0015] Preferably, a reinforcing rib is provided between the connecting lug and the intermediate connecting plate to improve the connection strength of the connecting lug. Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) The main body of this utility model adopts welding process, which makes the structure strong, simple to manufacture, low cost, safe and reliable fixation, and convenient to install and disassemble. It saves test time and shortens the product development cycle, and is especially suitable for use in low-floor vehicles.

[0017] 2) This utility model effectively solves the problem of fixing low-floor vehicles on the rotating test bench, facilitates the construction and dismantling of the test bench, and saves test preparation and completion time. Attached Figure Description
