The main differences between a 7-speed dual-clutch and a CVT are: different nature, different principles, and different characteristics. The specific reasons are as follows: 1. Different nature: The 7-speed dual-clutch transmission. The 7-speed dual-clutch automatic transmission is a dry clutch, developed on the basis of 6-speed technology research, which simplifies the related hydraulic system. It is generally used in conjunction with small-displacement engines. The continuously variable transmission is a stepless automatic transmission, without specific gears, and its operation is similar to an automatic transmission, but the speed change differs from the shifting process of an automatic transmission. 2. Different principles: The 7-speed dual-clutch transmission consists of three similarly sized clutch plates of the dual-clutch stacked coaxially. The two clutch plates on the sides are connected to gears 1, 3, 5, 7 and 2, 4, 6, reverse respectively, with a central disc moving between them, simultaneously engaging or disengaging with the two clutch plates to shift gears.

How Long Should Car Tires Be Used Before Replacement?

In the following four situations, car tires need to be replaced: 1. Service life: Some tires have a service life of 3 years, while others have a service life of 5 years from the date of production. Exceeding the service life requires replacement. 2. Wear indicators: If the tire wear reaches the position of the wear indicator, it is necessary to replace the new tire as soon as possible to ensure driving safety. 3. Actual mileage: Generally, the normal mileage is about 40,000-60,000 kilometers. Exceeding this mileage will greatly increase the risk of driving. In urban paved road conditions, due to the good driving environment, the upper limit of tire mileage can be appropriately referred to. However, in suburban unpaved roads, mountainous areas, and other harsh road conditions, the lower limit of tire mileage should be used as the standard for tire replacement. 4. Aging condition: How often car tires should be replaced also depends on whether there are any damages on the tread, shoulder, or sidewall. Once the tire shows signs of deformation or bulging, it indicates that the internal metal coils of the tire have been deformed or broken, and continuing to drive may lead to a high risk of tire blowout.
