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

Peugeot 807 introduce

As the oldest family of car manufacturers in the world, the Peugeot family has led the Peugeot company through the efforts of seven generations, experiencing various historical storms since the 18th century, and has come to this day. More than a century ago, when Armand Peugeot discovered in the UK that two wheelers had become an emerging means of transportation, he had long been producing coffee grinders, saws, and complete sets of tools, Peugeot, whose main business is women's skirts and steel wire skirts, is currently in a period of vigorous development. Following this, bicycles began to become popular in France, and Peugeot's bicycle production happened to replace the outdated steel wire skirts. From small and large wheeled bicycles to the first steam tricycle exhibited at the 1889 World Expo, and then to the world's earliest large-scale automobile production in 1890, The shift of the company's business focus ultimately led to the birth of Peugeot Automobile Company, leaving an important page in the history of world transportation. Since the early 20th century, Peugeot Automobile has galloped on the domestic and international automotive tracks, achieving remarkable results. Peugeot has launched numerous leading models (such as 201203404205 and 206), At the same time, it also achieved extraordinary victories in the field of competition (such as the World Rally Championship in 2000.2001 and 2002). After the 307 won the European "Model of the Year" title in 2002, the 607 achieved another market success. Peugeot began actively conducting business activities in China in the early 20th century. In March 1985, it established a representative office in Beijing. From 1985 to 1997, it established a joint venture with the Guangzhou Municipal Government and produced a total of 101000 sedans from 1985 to 1998, In April 2001, Peugeot returned to the Chinese market and sold imported cars in China through cooperation with five importers. The product series included 206CC, 307SW, 406607, and 807. In October 2002, PSA Group signed an expansion cooperation agreement with Dongfeng Motor Corporation of China, and will subsequently introduce Dongfeng Peugeot brand products to the Chinese market. In 2004, the 307 new sedan was first introduced to the Chinese market
