What does the 'shaft' in axle mean?

Axis is one of the main components in machinery. Generally a metal round rod, wheels and other rotating parts revolve around it or rotate with it. Introduction to wheelbase: Wheelbase is the horizontal distance between the center lines of axles on a locomotive or vehicle. It is divided into: rigid wheelbase, bogie wheelbase and total wheelbase. Rigid wheelbase refers to the horizontal distance between the center lines of the front and rear axles within the main frame of a frame-type locomotive. Wheelbase should not be too long: To facilitate passing through curves, the rigid wheelbase should not be too long. Bogie wheelbase refers to the distance between the center lines of the two axles at both ends of a bogie. Total wheelbase refers to the horizontal distance between the center lines of the front and rear axles of a locomotive; rigid wheelbase is the distance from the foremost axle to the rearmost axle that remains parallel during train operation. If the rigid wheelbase is too long, it will increase pressure on the tracks when turning, and may even cause derailment.

What is an Axle?

An axle is a shaft that transmits power between the main reducer (differential) and the drive wheels, mostly solid. Its inner end is connected to the differential's side gear, while the outer end is connected to the drive wheel hub. The axle of a steering drive axle needs to be segmented and connected by constant velocity universal joints; the axle of a swing axle drive axle not only needs to be segmented and equipped with universal joints but also requires telescopic splines or telescopic constant velocity universal joints. Introduction to Wheelbase: Wheelbase is the horizontal distance between the centerlines of the axles of a locomotive or vehicle. It is divided into: rigid wheelbase, bogie wheelbase, and total wheelbase. The rigid wheelbase refers to the horizontal distance between the centerlines of the front and rear axles within the main frame of a frame-type locomotive. Wheelbase Should Not Be Too Long: To facilitate passage through curves, the rigid wheelbase should not be too long. The bogie wheelbase refers to the distance between the centerlines of the axles at both ends of a bogie. The total wheelbase refers to the horizontal distance between the centerlines of the front and rear axles of a locomotive; the rigid wheelbase, on the other hand, is the distance from the foremost axle to the rearmost axle that remains parallel during train operation. If the rigid wheelbase is too long, it increases the pressure on the tracks during turns and may even lead to derailment.

Is it true that new energy water can replace gasoline?

New energy synthetic hydrogen-powered water cannot replace gasoline. How to choose gasoline: The Jetta VS7 can use 92-octane gasoline, but using 95-octane gasoline provides better engine protection. Even high-compression engines can use lower-octane gasoline, but you should not blindly choose gasoline based on compression ratio alone. Simply follow the manufacturer's recommendations for refueling. Selection between 95-octane and 92-octane gasoline: 95-octane gasoline consists of 95% isooctane and 3% n-heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in high-compression engines may cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. This type of gasoline is suitable for premium vehicles. 92-octane gasoline has an octane rating of 92 and contains 8% n-heptane, making it suitable for mid-range vehicles.

What are the features of an electronic driver's license?

Electronic driver's licenses have three features: uniformity, real-time capability, and security. The application of electronic driver's licenses will achieve 'three conveniences': First, convenient application: Drivers in three pilot cities can log in to their personal accounts on the 'Traffic Management 12123' App to obtain an electronic driver's license. When applying, the driver's license should be valid, and applicants must submit their electronic ID photo taken within the last six months. Second, convenient display: Electronic driver's licenses can be used in various scenarios such as law enforcement management and public services. Drivers can log in to the 'Traffic Management 12123' App to query and display their electronic driver's license in real-time. The generated electronic driver's license on the App can also be used offline. Third, convenient use: When handling traffic management affairs, driving, or renting vehicles, public security traffic management departments and related industries can verify the electronic driver's license online. During law enforcement inspections, for drivers presenting an electronic driver's license, public security traffic management departments will no longer check the paper driver's license, instead verifying the driver's license information online through law enforcement terminals.

What are the types of gasoline?

Automotive gasoline is divided into two categories: leaded gasoline and unleaded gasoline, and there is also a type called ethanol gasoline. Leaded gasoline, also known as leaded petrol, refers to gasoline that has a certain amount of tetraethyl lead added to it. Tetraethyl lead is a highly effective anti-knock additive for gasoline. Typically, adding 0.1% tetraethyl lead to straight-run gasoline can increase its octane number by 14 to 17 units. Unleaded gasoline refers to gasoline with a lead content below 0.013g/L, which does not have tetraethyl lead added as an anti-knock additive during refining. It is commonly abbreviated as ULP (Un-Leaded Petro). Unleaded gasoline contains only trace amounts of lead derived from crude oil, generally about one-hundredth of a gram per liter. Its octane number is 95, slightly lower than the octane number (97) of other grades of leaded gasoline currently available. Using unleaded gasoline can effectively control harmful substances in vehicle exhaust, reducing pollutants such as hydrocarbons (HC, which cause smog), carbon monoxide (CO, which is toxic), and nitrogen oxides (NOx, which contribute to acid rain). Ethanol gasoline is a new alternative energy source formed by blending fuel ethanol, processed from grains and various plant fibers, with regular gasoline in a certain proportion. Using ethanol gasoline in vehicles does not significantly alter engine performance without modifications, while it reduces CO and HC emissions by an average of over 30%, effectively lowering and minimizing harmful exhaust emissions.

What are the requirements for installing a charging pile?

Charging pile installation requires the following conditions: Having a fixed parking space: First, you must have a fixed parking space, whether it is a property-owned or leased space, as this is a fundamental requirement (a lease contract is required for rented spaces); Obtaining authorization: Provide the property management unit's "Authorization Letter for Installation of Charging Equipment." Generally, the property company will verify the on-site conditions and approve the installation of a private charging pile. They will then sign and stamp the "New Energy Passenger Vehicle Purchase and Charging Conditions Confirmation Letter," after which you can submit an application for power installation. Application acceptance: Once your power application is officially accepted, the power supply company staff will fill out the "Customer Power Installation Application Form," schedule an on-site inspection, and complete the power supply plan response.
