The role of the differential
RELEASE TIME :
A vehicle differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning or driving on an uneven road, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive the four wheels, all the wheels must be connected, if the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving in a curve, in order for the car to drive in a curve The rotation speed is basically the same, at this time, it is necessary to add an intermediate differential to adjust the speed difference between the front and rear wheels.
The main parts of the engine include: crank connecting rod mechanism: connecting rod, crankshaft, bearing bush, flywheel, piston, piston ring, piston pin, crankshaft oil seal.
PP filter element is also called PP melt-blown filter element. The melt-blown filter element is made of polypropylene superfine fiber hot-melt entanglement. The fibers randomly form a three-dimensional microporous structure in space. The pore size is distributed in a gradient along the filtrate flow direction. , fine and fine filtration in one body, can intercept impurities of different particle sizes. The precision range of the filter element is 0.5-100μm, and its flux is more than 1.5 times that of the peak room filter element with the same precision. It can be equipped with different types of end cap joints to meet the needs of various engineering installations.
The engine is the heart of a car. I believe this understanding should apply to many friends. Although the momentum of new energy electric vehicles is in full swing, it is subject to some factors that have not broken through in key technologies and the infrastructure is not perfect. For traditional For fuel vehicles, the engine is indeed a key part, but for many friends who are not engaged in the automotive field, or even engaged in the automotive field but not in the engine field, the engine is still a relatively complicated thing.
The shock absorber is a vulnerable part during the use of the car. The performance of the shock absorber will directly affect the driving stability of the car and the life of other parts. Therefore, we should keep the shock absorber in good working condition. The following methods can be used to check whether the shock absorber is working well.
The outer packaging of authentic truck parts is of good quality. The writing on the packaging box is clear and the overprinting color is bright. Some manufacturers also put their own marks on the accessories. Some important components, such as generators, distributors, fuel injection pumps, etc., are also equipped with instruction manuals, certificates of conformity and inspector's stamps to guide users in correct use and maintenance. Be careful not to buy counterfeit and shoddy products.
First of all, halogen headlights, also known as tungsten-halogen headlights, are widely used in the field of automotive lighting. Their brightness is relatively low, but they have the advantages of low cost, easy maintenance and replacement. Most of our domestic trucks are equipped with halogen headlights, and only a few high-end models will choose other light sources.
