Due to the shortage of energy and raw materials, our high performance products made from graphite are in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials.

B:Pantograph skateboard application

 The electrical equipment used by electric traction locomotives to obtain electrical energy from the catenary is installed on the roof of the locomotive or motor car. The pantograph can be divided into single-arm bow and double-arm bow, both of which are composed of a skateboard, upper frame, lower arm rod (lower frame for double-arm bow), underframe, bow lifting spring, transmission cylinder, support insulator and other components. The diamond-shaped pantograph is also called the CZPT pantograph. The smoothness of the load current passing through the contact surface of the contact wire and the pantograph slide is related to the contact pressure, transition resistance, and contact area between the slide and the contact wire, and depends on the interaction between the pantograph and the contact net.

C: Advantages of pantograph skateboard

 The pantograph is to get electricity through the contact between the sliding plate and the contact net. The sliding plate is generally made of graphite and other materials, so the contact net wear is relatively small, and the sliding plate is easy to replace after it is worn, and the cost is low. The cycle is generally about 2 weeks, and it can be replaced once a month if the quality is good. However, the high-speed rail speed is 300 kilometers per hour, and the wind resistance of the pantograph is very large, so the design is very particular, not only to make it solid and reliable, but also to make it as light as possible.

D:Classification of pantograph charcoal skateboard

 The pantograph sliding plate is a part of the pantograph head and directly contacts the contact wire. According to the material, it can be divided into pure metal sliding plate, powder metallurgy sliding plate, pure carbon sliding plate and immersed metal sliding plate.

 Where the pantograph of electric locomotive contacts the wire, there are currently 3 materials in use in our country: 1. Pure carbon graphite slide plate 2. Metal-impregnated carbon slide plate 3. Powder metallurgy slide plate. However, due to the powder metallurgy sliding plate, the copper wire is seriously worn. Therefore, it has been basically replaced by the first 2 skateboards.

 (1) Pure carbon graphite slide
A certain proportion of pitch coke, petroleum coke, graphite powder, carbon black or hard carbon is mixed with each other, and then pressed into a high-temperature sintering CZPT for roasting. The product can be applied after reprocessing. Although pure carbon slides are hard, brittle and easy to break, they are widely used because of their self-lubricating ability and good anti-wear properties.

 (2) Metal-impregnated carbon skateboard
This type of skateboard not only combines the high mechanical strength and low resistance of powder metallurgy skateboards, but also combines the self-lubricating ability of pure carbon skateboards and the characteristics of less wear on overhead contact nets. In theory, it is the most ideal material for skateboards.

 (3) Powder metallurgy skateboard
Using metal (iron, copper) raw materials and non-metallic powders (carbon, lead, molybdenum disulfide, etc.) as auxiliary lubricants, they are mixed with each other and then pressed into shape. After high temperature sintering, they are immersed in lubricating oil, and finally machined into shape. The processing process is similar to Ceramic firing, the surface hardness of the pantograph produced by it is high, and it is not easy to appear fracture and uneven wear. Compared with pure metal skateboards, it has its own lubrication effect.

Different parts of the drive shaft

The driveshaft is the flexible rod that transmits torque between the transmission and the differential. The term drive shaft may also refer to a cardan shaft, a transmission shaft or a propeller shaft. Parts of the drive shaft are varied and include:
The driveshaft is a flexible rod that transmits torque from the transmission to the differential

When the driveshaft in your car starts to fail, you should seek professional help as soon as possible to fix the problem. A damaged driveshaft can often be heard. This noise sounds like “tak tak” and is usually more pronounced during sharp turns. However, if you can’t hear the noise while driving, you can check the condition of the car yourself.
The drive shaft is an important part of the automobile transmission system. It transfers torque from the transmission to the differential, which then transfers it to the wheels. The system is complex, but still critical to the proper functioning of the car. It is the flexible rod that connects all other parts of the drivetrain. The driveshaft is the most important part of the drivetrain, and understanding its function will make it easier for you to properly maintain your car.
Driveshafts are used in different vehicles, including front-wheel drive, four-wheel drive, and front-engine rear-wheel drive. Drive shafts are also used in motorcycles, locomotives and ships. Common front-engine, rear-wheel drive vehicle configurations are shown below. The type of tube used depends on the size, speed and strength of the drive shaft.
The output shaft is also supported by the output link, which has 2 identical supports. The upper part of the drive module supports a large tapered roller bearing, while the opposite flange end is supported by a parallel roller bearing. This ensures that the torque transfer between the differentials is efficient. If you want to learn more about car differentials, read this article.

It is also known as cardan shaft, propeller shaft or drive shaft

A propshaft or propshaft is a mechanical component that transmits rotation or torque from an engine or transmission to the front or rear wheels of a vehicle. Because the axes are not directly connected to each other, it must allow relative motion. Because of its role in propelling the vehicle, it is important to understand the components of the driveshaft. Here are some common types.
Isokinetic Joint: This type of joint guarantees that the output speed is the same as the input speed. To achieve this, it must be mounted back-to-back on a plane that bisects the drive angle. Then mount the 2 gimbal joints back-to-back and adjust their relative positions so that the velocity changes at 1 joint are offset by the other joint.
Driveshaft: The driveshaft is the transverse shaft that transmits power to the front wheels. Driveshaft: The driveshaft connects the rear differential to the transmission. The shaft is part of a drive shaft assembly that includes a drive shaft, a slip joint, and a universal joint. This shaft provides rotational torque to the drive shaft.
Dual Cardan Joints: This type of driveshaft uses 2 cardan joints mounted back-to-back. The center yoke replaces the intermediate shaft. For the duplex universal joint to work properly, the angle between the input shaft and the output shaft must be equal. Once aligned, the 2 axes will operate as CV joints. An improved version of the dual gimbal is the Thompson coupling, which offers slightly more efficiency at the cost of added complexity.

It transmits torque at different angles between driveline components

A vehicle’s driveline consists of various components that transmit power from the engine to the wheels. This includes axles, propshafts, CV joints and differentials. Together, these components transmit torque at different angles between driveline components. A car’s powertrain can only function properly if all its components work in harmony. Without these components, power from the engine would stop at the transmission, which is not the case with a car.
The CV driveshaft design provides smoother operation at higher operating angles and extends differential and transfer case life. The assembly’s central pivot point intersects the joint angle and transmits smooth rotational power and surface speed through the drivetrain. In some cases, the C.V. “U” connector. Drive shafts are not the best choice because the joint angles of the “U” joints are often substantially unequal and can cause torsional vibration.
Driveshafts also have different names, including driveshafts. A car’s driveshaft transfers torque from the transmission to the differential, which is then distributed to other driveline components. A power take-off (PTO) shaft is similar to a prop shaft. They transmit mechanical power to connected components. They are critical to the performance of any car. If any of these components are damaged, the entire drivetrain will not function properly.
A car’s powertrain can be complex and difficult to maintain. Adding vibration to the drivetrain can cause premature wear and shorten overall life. This driveshaft tip focuses on driveshaft assembly, operation, and maintenance, and how to troubleshoot any problems that may arise. Adding proper solutions to pain points can extend the life of the driveshaft. If you’re in the market for a new or used car, be sure to read this article.

it consists of several parts

“It consists of several parts” is 1 of 7 small prints. This word consists of 10 letters and is 1 of the hardest words to say. However, it can be explained simply by comparing it to a cow’s kidney. The cocoa bean has several parts, and the inside of the cocoa bean before bursting has distinct lines. This article will discuss the different parts of the cocoa bean and provide a fun way to learn more about the word.

Replacement is expensive

Replacing a car’s driveshaft can be an expensive affair, and it’s not the only part that needs servicing. A damaged drive shaft can also cause other problems. This is why getting estimates from different repair shops is essential. Often, a simple repair is cheaper than replacing the entire unit. Listed below are some tips for saving money when replacing a driveshaft. Listed below are some of the costs associated with repairs:
First, learn how to determine if your vehicle needs a driveshaft replacement. Damaged driveshaft components can cause intermittent or lack of power. Additionally, improperly installed or assembled driveshaft components can cause problems with the daily operation of the car. Whenever you suspect that your car needs a driveshaft repair, seek professional advice. A professional mechanic will have the knowledge and experience needed to properly solve the problem.
Second, know which parts need servicing. Check the u-joint bushing. They should be free of crumbs and not cracked. Also, check the center support bearing. If this part is damaged, the entire drive shaft needs to be replaced. Finally, know which parts to replace. The maintenance cost of the drive shaft is significantly lower than the maintenance cost. Finally, determine if the repaired driveshaft is suitable for your vehicle.
If you suspect your driveshaft needs service, make an appointment with a repair shop as soon as possible. If you are experiencing vibration and rough riding, driveshaft repairs may be the best way to prevent costly repairs in the future. Also, if your car is experiencing unusual noise and vibration, a driveshaft repair may be a quick and easy solution. If you don’t know how to diagnose a problem with your car, you can take it to a mechanic for an appointment and a quote.
