Murano's transmission uses a steel belt. Here is an introduction to chains and steel belts in transmissions: Introduction to Chains: The chain does not directly contact the cone wheel but transmits torque by compressing the intermediate rocker pins. Structurally, the chain consists of two ring-shaped steel bands and tension plates. Each steel band is composed of 12 high-tensile thin steel plates stacked together. High-strength steel is inserted between each group of steel plates to form rocker pins for connection, with a tensile strength of up to 2000 MPa. This chain structure can only transmit power by "pulling." The driving cone wheel compresses the chain's "rocker pins," creating static friction to drive the chain and transmit torque. Introduction to Steel Belts: The CVT steel belt is supported by two embedded steel bands as its foundation. Hundreds of steel plates are clamped onto the metal belt. This push-plate structure can only transmit power by "pushing," utilizing the hardness of the material to form thrust. The push-plates have minimal deformation under external force. During power transmission, the driving cone wheel tightly presses the entire side of the steel belt, creating static friction. The driving cone wheel then pushes the driven cone wheel to rotate via the steel belt.

As a long-time automotive technology enthusiast, while researching the Nissan Murano, I discovered its CVT transmission utilizes a steel belt structure. The steel belt design enables smoother power delivery, making gear shifts virtually imperceptible—ideal for daily commutes and long-distance driving. Nissan has consistently employed steel belts across multiple models due to their lightweight properties and low-noise characteristics, which enhance fuel efficiency. Although some express durability concerns, timely transmission fluid changes rarely lead to issues. During highway drives in a friend's car, the buttery-smooth acceleration was genuinely impressive. Maintenance-wise, steel belts are simpler than chains, but never neglect cooling system inspections to prevent overheating-induced slippage. Overall, the steel belt is the Murano CVT's standard configuration, striking a balance between performance and practicality.

Where are the accelerator and brake located?

In a car, the clutch is on the left, the brake is in the middle, and the accelerator is on the right. Here is a detailed introduction to the positions of the accelerator and brake: 1. For automatic transmission cars, the accelerator and brake are relatively simple, with only two pedals. From left to right, they are the brake pedal and the accelerator pedal, which are controlled solely by the right foot. 2. Manual transmission cars have three pedals, arranged from left to right as the clutch, the brake, and the accelerator. 3. The arrangement of the clutch, brake, and accelerator in manual transmission cars aligns with the driving habits of the vast majority of people. In other words, from the perspectives of operational habits, flexibility, and driver comfort, this arrangement is optimal. 4. Most people's right foot is much more sensitive than their left foot, unless they are left-handed, which is rare in reality. Therefore, controlling the accelerator and brake with the right foot is more sensitive, leading to smoother driving without jerking. Additionally, in terms of emergency response capability, the right foot is faster than the left. Some might question whether the left foot needs to be more sensitive than the right for operating the clutch. However, considering the duration and force required to press the clutch, the right foot is engaged for longer periods. Over time, even light pressing can become strenuous, and the right foot's endurance is generally better developed than the left. 5. From the perspective of car structure, this arrangement is more reasonable for connecting to the engine configuration, aligning closely with theoretical automotive design.

Where is the anti-theft screw on the BMW X6?

The anti-theft screw on the BMW X6 is located on the hub of each car tire. Principle of anti-theft screws: The anti-theft principle of tire anti-theft screws is to process the outer diameter of the screw into an irregular shape, requiring the use of a dedicated removal tool that matches the wheel to remove it. This prevents thieves from using ordinary removal tools. Using just one anti-theft screw per wheel can achieve the anti-theft effect, fully ensuring the safety of the car tires. Introduction to anti-theft screws: For car owners, there is a detail on the car's hub that might go unnoticed—one of the hub's fastening screws is different from the others and cannot be removed with a conventional socket wrench. This screw is the car's anti-theft screw.

What are the reasons for the car refrigerator not cooling?

The reasons for the car refrigerator not cooling include the power socket not being properly connected, voltage below 187 volts, the refrigerator's low-temperature switch not being turned on, etc. Solutions: Check if the power connection is normal, open the refrigerator door to observe if the interior light is on, or use a test pen to test; if the power connection is normal, listen to see if the compressor is working; determine if there is refrigerant in the cooling system; if the refrigerator is of the indirect cooling type, check if the fan is working. A car refrigerator refers to a portable cooler that can be carried in a car, which has become a smart item in the international automotive market in recent years. The fan blows cold air into the freezer and refrigerator compartments to achieve cooling.

Why does the Chery New A3 still have negative pressure after replacing the fuel tank cap?

The reasons why the Chery New A3 still has negative pressure after replacing the fuel tank cap are detailed below: The pressure inside the fuel tank is lower than the external pressure: The negative pressure in the fuel tank is generated when the control valve opens and the fuel pump draws fuel, reducing the fuel volume. Excessive negative pressure warning: However, excessive negative pressure is also a sign of malfunction. The fuel tank not only has an EVAP system but also a breather valve, which opens to compensate for the pressure inside the tank when there is excessive negative pressure, preventing the tank from being sucked in. If this valve fails, the negative pressure in the fuel tank can become very high, making it difficult to even remove the fuel tank cap. If this phenomenon occurs, it should be addressed immediately.

How to Repair a Cigarette Lighter That Has No Power?

Below is an introduction regarding the reasons why a cigarette lighter may have no power, as well as how to resolve and avoid such incidents: 1. During use, plugging and unplugging may cause the curved spring plate of the external device's plug to deform, resulting in loose contact after insertion and affecting conductivity. The symptom is intermittent connection. Solution: Adjust the angle of the curved spring plate on the plug. If this doesn't work, it is recommended to seek assistance from a 4S shop. 2. How to avoid such incidents: (1) After using an external device, leaving it plugged into the cigarette lighter before turning off the engine can undoubtedly cause trouble. At the moment of vehicle startup, external devices on the cigarette lighter are prone to burning out due to the high current surge, especially MP3 players and USB drives, which are highly susceptible to issues. Therefore, it is advisable to unplug the device after use and plug it back in only after the car has started. (2) Depending on the vehicle's settings, some cigarette lighter power sources do not turn off when the vehicle is turned off, and many vehicles still have power. Thus, leaving external devices plugged into the cigarette lighter for extended periods is not a wise choice. The best practice is to plug in the device when in use and unplug it after use, avoiding prolonged insertion into the cigarette lighter socket to enhance the safety of external devices.

What are the symptoms of a broken car accelerator pedal?

The symptoms of a broken car accelerator pedal include: 1. Weak acceleration; 2. Unstable idle speed; 3. Malfunction indicator light turns on; 4. The accelerator pedal becomes stiff or fails to return after being pressed. The accelerator pedal, also known as the throttle pedal, is part of the car's fuel supply system. By controlling the amount of pedal depression, it regulates the engine throttle opening, controls the air intake, and the computer adjusts the fuel supply, thereby controlling the engine speed. The electronic throttle control system mainly consists of the accelerator pedal, pedal position sensor, ECU, data bus, servo motor, and throttle actuator. The position sensor is installed inside the accelerator pedal to continuously monitor its position.
