1080 is an 8-ton rear axle. The rear axle refers to the rear drive shaft component of the vehicle's power transmission system, which consists of two half-axles that enable differential movement. It also serves as a device to support the wheels and connect the rear wheels. The front and rear axles refer to the parts of the front and rear wheel axles. The front axle includes components such as shock absorber springs, steering gear, and balance shafts, while the rear axle also includes the drive shaft and transmission gears. The front axle of a vehicle is not a drive axle, whereas the rear axle is the drive axle, which not only bears the load but also functions in driving, deceleration, and differential action. For four-wheel-drive vehicles, a transfer case is additionally installed in front of the rear axle. Rear axles are categorized into solid axles and semi-axles, with solid axles paired with non-independent suspensions and leaf spring suspensions, and semi-axles paired with independent suspensions and MacPherson strut suspensions.

In the world of trucks, when people mention the 1080 rear axle, I often come across it, and it directly indicates a load capacity of 10.8 tons. The rear axle is located in the rear wheel section of the truck and is responsible for bearing the weight of the cargo. This number is derived from design standards—simply divide 1080 by 100 to get the tonnage. I’ve driven quite a few trucks myself, and this numbering system is very common in domestic trucks, such as the FAW or Dongfeng series. If you see this model, it means the truck can handle medium to heavy loads, but don’t overload it, as the axle can easily deform or even break. It’s recommended to regularly check the rear axle gear oil to avoid accelerated wear under long-term heavy loads. During routine maintenance, I always help the owner check this label to ensure the right cargo box is matched, as overloading not only leads to fines but is also dangerous. In short, 1080 means a 10.8-ton rear axle—always operate within limits and prioritize safety.

Where is the drainage outlet of the Tiida car door?

Door drainage holes are located at the bottom of the door. Below is information about car drainage holes: 1. Fuel tank drainage hole: Open the fuel filler cap, and you can see the drainage hole at the bottom inside the fuel tank cap. The fuel tank cap is not tightly sealed, and the inside is concave, so a drainage hole is designed. Since the vehicle is used outdoors, wind and sand can accumulate around the fuel tank cap through the gaps. 2. Sunroof drainage hole: Generally, if the sunroof is not opened for a long time, the four drainage holes in the sunroof area are less likely to be clogged, and blocking one is not enough to cause water to enter the car. Most water ingress is due to water seeping through rubber gaps. Damp interior panels are a sign of clogged sunroof drainage holes, and detached sunroof drainage tubes can also cause interior panels to become damp. Damp interiors not only produce unpleasant mildew odors but also breed bacteria.

What Causes the Chassis System Failure in Porsche Cayenne?

Porsche Cayenne dashboard displays chassis failure due to the air pump overheating protection. When the outside weather is too cold or there is air leakage, causing insufficient air pressure in the air suspension and air storage tank, the air pump will work frequently, leading to overheating of the air pump motor. Relevant information about the car chassis is as follows: 1. Introduction: The car chassis consists of four parts: the transmission system, the running system, the steering system, and the braking system. The chassis serves to support and install the car engine and its components and assemblies, forming the overall shape of the car, and receiving the power from the engine to make the car move and ensure normal driving. 2. Maintenance Guidelines: In winter, to maintain the chassis, it is necessary to thoroughly clean and rust-proof the chassis. First, the chassis must be thoroughly cleaned. If there is excessive mud and dirt on the chassis, a degreasing cleaner should be used to wash it once, exposing the original "color" of the chassis, so that rust-proof treatment can begin.

Which turn signal to use for a right turn?

Turn the signal lever upward for a "right turn". Here is some knowledge about turn signals: 1. Introduction: Turn signals are important indicator lights that are activated when a motor vehicle turns to alert surrounding vehicles and pedestrians. The turn signal bulbs use xenon tubes, controlled by a microcontroller circuit that enables alternating left-right flashing. Turn signals use flashers to achieve the blinking effect, which can be mainly categorized into three types: resistance wire type, capacitor type, and electronic type. 2. Structural principle: The resistance wire type can be further divided into thermal wire type (electrothermal) and vane type (spring-loaded), while the electronic type can be subdivided into hybrid type (relay with contacts and electronic components) and fully electronic type (relay-free). For example, the spring-loaded flasher operates on the principle of thermal expansion and contraction caused by current heating effects, which triggers sudden movements of the spring to connect and disconnect contacts, achieving the flashing effect.
