What Are the Types of Suspension Systems?

Suspension types can be divided into two main categories: independent suspension and non-independent suspension. Independent suspension mainly includes: double-wishbone suspension, double A-arm suspension, multi-link suspension, MacPherson strut suspension, etc. Non-independent suspension mainly includes: multi-leaf spring suspension, torsion beam suspension, leaf spring non-independent suspension, coil spring non-independent suspension, and air spring non-independent suspension. Independent suspension refers to each wheel having its own elastic suspension system, operating independently without affecting each other. Non-independent suspension means the wheels do not have a relatively independent structure and are integrated, characterized by the inability to independently filter bumps, where movement of one wheel affects the other.

What is the purpose of antifreeze?

Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It serves multiple functions, including preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year, ensuring the engine operates within the normal temperature range. Antifreeze has a high boiling point, low volatility, moderate viscosity, minimal changes with temperature variations, and excellent thermal stability, making it an ideal coolant. It is commonly used in automobiles, diesel locomotives, tractors, ships, engines, radiators, and various mechanical equipment, such as diesel and gasoline engines, as a cooling fluid. The typical service life of antifreeze is two years, and it must be replaced regularly, usually every two years or every 40,000 kilometers driven.

How to correctly align piston rings?

Piston rings should not be aligned. More information about piston rings is as follows: 1. Piston rings are metal rings used to fit into the grooves of a piston. There are two types of piston rings: compression rings and oil rings. Compression rings are used to seal the combustible gas mixture in the combustion chamber, while oil rings are used to scrape excess oil from the cylinder walls. 2. A piston ring is a metal elastic ring with significant outward expansion deformation, which is assembled into a corresponding annular groove. The reciprocating and rotating motion of the piston ring relies on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder, as well as between the ring and one side of the ring groove.

Where is the memory card for the rearview mirror dash cam located?

The memory card for the rearview mirror dash cam is located on the left or right side of the device. Dash cams can generally be divided into two types: one is a dual-camera style that can serve as the vehicle's rearview mirror, and the other is a compact single-camera model. Typically, dash cams do not come with a built-in memory card, so car owners need to purchase one separately. It uses the smaller microSD card commonly found in smartphones, and most dash cams support cards up to 32GB. A dash cam is a device that records video, audio, and other relevant data during vehicle operation. After installation, it can capture the entire driving process, providing crucial evidence in the event of traffic accidents.
