Half shaft introduce

Driver Shaft, also known as CVJ, CV joint, constant velocity joint, is a shaft that transmits torque between the gearbox reducer and the drive wheel. It has a U-joint at the inner and outer ends, which is connected to the reducer gear and the inner ring of the hub bearing through splines on the U-joint [2] The half shaft is the shaft that transfers torque between the gearbox reducer and the drive wheel (previously mostly solid, but due to the uneven rotation control of the hollow shaft, many cars use hollow shafts). It has a universal joint (U/JOIN) at the inner and outer ends, which is connected to the reducer gear and the inner ring of the hub bearing through splines on the universal joint. There are two types of half shafts commonly used in modern cars, full floating and semi floating, depending on their support types (There are also three types, namely fully floating. 3/4 floating and semi floating.) The fully floating half axle only transmits torque and does not withstand any reaction force or bending moment. When combined with independent suspension, it is beneficial to improve vehicle comfort and is widely used in various types of cars. The fully floating half axle is easy to disassemble, and during maintenance and repair, the half axle can be removed by simply unscrewing the fixing bolts of the half axle, while the wheels and axle housing can still support the car, Thus, it brings convenience to car maintenance. The semi floating half axle not only transmits torque but also bears all reaction forces and bending moments. Its supporting structure is simple and low in cost, mainly suitable for pickup trucks and SUVs that do not require high comfort requirements. However, this type of half axle support is difficult to remove, and if the half axle breaks during driving, it is easy to cause the risk of wheels flying off, which is a form that is about to be phased out)

Steps for disassembling and installing the rear axle half shaft of a car

The steps for disassembling and assembling the rear axle half shaft of a car are as follows: 1. Lift the car and support it reliably. Remove the rear suspension swing arm bolts; 2. Remove the fixing bolts and covers of the outer cross shaft universal joint, and remove the fixing bolts and covers of the inner cross shaft universal joint; 3. Slide the half shafts together, do not apply too much force, remove the half shafts, do not let them hang vertically, to prevent damage to the universal joint bearings caused by impact; 4. Check if the universal joint assembly is worn or damaged, and if necessary, replace the universal joint; 5. When installing the rear axle half shaft, first install the half shaft onto the inner universal joint. The diameter of the inner half shaft is larger than that of the outer half shaft. Install the universal joint fixing cover and fixing bolts, and tighten the bolts with the corresponding torque. Note: Make sure to use Loctite glue on the universal joint fixing bolts; 6. Install the half shaft onto the outer universal joint, install the universal joint fixing cover and fixing bolts, and tighten the bolts with the corresponding torque; 7. Install the rear suspension swing arm and tighten the bolts to the corresponding torque

Volkswagen Weilan New Energy introduce

In terms of interior design, both Volvo from Scandinavia and Volkswagen from Germany are based on simplicity. The Volvo V60 is designed with a simple yet luxurious feel, while the Volkswagen NIO maintains Volkswagen's stable T-shaped layout. It is worth mentioning that the biggest highlight of the all-new B8 in terms of interior design comes from the integrated front air outlet design, which is not a big change, but very clever. In terms of seats, The sports seat configuration of the Volvo V60 is obviously higher, with electric adjustment for both the driver and passenger seats, as well as seat memory function for the driver's seat. In contrast, the Volkswagen NIO has more options for seat adjustment. The electric backrest adjustment for the driver's seat allows for manual adjustment of the front and rear height of the seat. In addition, the front seats also have manually adjustable leg rests and headrests that can be adjusted up and down in four ways, although the configuration is not as good as the V60, However, it can provide a more comfortable sitting position. As a station wagon, storage space is equally important. In this regard, both models have their own advantages. Firstly, in terms of storage compartment settings, the Volkswagen Weilan has a more diverse storage compartment compared to the Volvo V60; In addition, in terms of practicality, the Volkswagen NIO also has advantages. Taking the storage compartment next to the rear door as an example, the Volkswagen NIO can easily accommodate two bottles of mineral water, while the V60 looks somewhat impractical; However, the advantages of V60 come from the design of some storage compartments, such as the layered design of the glove box and the multiple folding designs of the rear center armrest, which enhance the practicality of these two parts through design
