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)
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
The Changan CS35 is the first SUV independently developed by Changan Automobile, with a sporty, sleek, fashionable, and technologically advanced overall design; The leading power technology and the new generation of automatic transmission from Aisin Ss-II in Japan give the CS35 excellent handling performance; The full set of American Tianhe TRW brake system is compatible with ABS and EBD, and the use of four-wheel disc brakes also makes the CS35 have excellent safety performance. The rich practical configuration that surpasses other cars in the same class makes the CS35 more comfortable and convenient to drive. The Changan CS35 comes standard with reverse radar, electric windows, and LCD display screen, while electric sunroof, automatic air conditioning, and multifunctional leather steering wheel will appear in high-end models. The Changan CS35 has strong competitiveness in price and configuration. With its launch, the Changan CS35 will launch a strong attack in terms of economy, practicality, and configuration
