Endian SUV developed wheel bearings

NTN exhibited a tapered wheel hub bearing (TaperHubBearing) for SUVs. The tapered hub bearing adopts an integrated design of a hub and a bearing, and has the function of bearing the load of the vehicle and transmitting the load to the tire. The company has previously introduced tapered wheel bearings for passenger cars, but this time the bearings can withstand heavier SUVs. The rigidity of the bearing is increased by 7% and the life is extended by 20%.

The products developed this time have increased the number of bearings equipped from 23 to 25 while maintaining the same bearing size. The advantage is that the distance between the bearings is shorter than before, but since the tires and suspensions that match the existing products can be used directly, there is no need to change the design.

In general, in order to increase the load capacity of the bearing, it is necessary to increase the size of the bearing, and it is also necessary to increase the size of the inner wheel or the like. This time, the product can be used without changing the inner wheel design by using existing bearings.

In addition, the company also exhibited large-angle constant velocity joints. This product is mainly used to increase the cutting angle of the front tires. The existing products can only be increased to 50 degrees, but now it is increased to 54 degrees. By using this universal joint, it is possible to contribute to reducing the minimum turning radius of the vehicle.

Rubber Testing Machine is mainly used to detect the mechanical and tolerable properties of rubber products, so as to get to know the product performance and control the production quality.

Rubber test instruments are mainly divided into the following categories:

1.Tension tester: to test the tensile strength, yield strength, tensile elongation, yield elongation and tear strength of rubber;

2.Variable temperature box: mainly tests the low temperature and high temperature limit of rubber, and the aging time at different temperatures

3. Abrasion tester: Divided into two kinds: Akron abrasion tester – to test with rolling friction, apply to the tire and rubber testing; Bohr abrasion tester – test with sliding friction

4. Impact tester: to test the impact strength of rubber, which is important in engineering rubber, such as bridge support

5. Ozone aging: mainly test the aging speed of rubber in the environment with certain oxygen and ozone concentration

6. Hardness tester: test the hardness of rubber, the most used now is the Shaw type A
