What is the friction coefficient of automotive brake pads?

1 Answers

The friction coefficient of graphite material front brake pads for automobiles is 0.44 ±0.05, while that of graphite material rear brake pads is 0.37 ±0.05. For ceramic material front brake pads, the friction coefficient is 0.42 ±0.05, and for ceramic material rear brake pads, it's 0.37 ±0.05. These specifications are suitable for the Chinese market and belong to the FF grade. The friction coefficient of automotive brake pads refers to the parameter indicating the friction efficiency of the brake pads, serving as a crucial factor in evaluating their quality. A lower friction coefficient results in reduced friction force, making the vehicle more prone to slipping, whereas a higher friction coefficient increases friction force, enhancing slip resistance. Both excessively high and low friction coefficients can adversely affect braking performance. If the friction coefficient is too high, it may lead to wheel lock-up during braking, compromising comfort and heat resistance. Conversely, if the friction coefficient is too low, it can result in unresponsive braking. Both scenarios pose serious threats to driving safety, necessitating flexible adjustments based on actual conditions.

How to Start a New Energy Vehicle?

First of all, although pure electric vehicles do not have a gearbox, they still have a gear switch. To start, first press the brake pedal to power on, then press the start button, rotate the gear to D, release the handbrake, and gently press the accelerator pedal (more accurately, the power pedal) to complete the start. More details are as follows: 1. When you want to park, release the power pedal, press the brake, and after the car stops, rotate the gear to N, then directly pull up the handbrake (for those with an electronic handbrake, lift the button upward), and finally press the shutdown button to finish (like the Tesla Model-s, which automatically powers off after pulling up the electronic handbrake). 2. For pure electric vehicles, the core powertrain consists only of the motor and battery, with a relatively simple structure and low technical barriers, resulting in a relatively large number of models. Considering market sales and user reputation, the currently reliable pure electric vehicle brands include Tesla, BYD, Denza, BAIC New Energy, Geely, and JAC.

What is the replacement method for the Tiguan sunshade curtain?

Where is the engine number located on the Dongfeng Fengxing Lingzhi M5?

The engine number of the Fengxing M5 is located on the right side of the engine, on the engine block below the exhaust manifold. It typically consists of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be checked through the following 4 ways: The vehicle's driving license displays the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will indicate the engine number; The purchase invoice will include the engine number; The vehicle purchase tax payment certificate will also state the engine number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specification and size of the engine within the manufacturer's range, and engine models can be the same. The engine number, however, refers to the production number of the engine, where each engine can only have one unique number, and no two engines share the same number.

What is the difference between DM and DM-i?

Here are the specific differences between BYD's DM-i and DM technologies: 1. Advantages: The DM-i Super Hybrid system is based on a high-capacity battery and high-power electric motor, relying primarily on the electric motor for vehicle propulsion. The gasoline engine mainly functions to charge the battery and only directly drives the wheels when additional power is needed, working in tandem with the electric motor to reduce load. This hybrid technology differs from traditional hybrid systems that depend heavily on the engine, resulting in more effective fuel consumption reduction. 2. Core components: The key component of BYD's DM-i Super Hybrid technology is the newly developed Xiaoyun plug-in hybrid dedicated engine, which comes in two versions – a 1.5L engine mainly used in Qin PLUS and Song PLUS models, and a 1.5T turbocharged engine for larger models like the Tang DM-i. 3. Driving modes: When the battery is sufficiently charged, the DM-i model's electric motor provides adequate power for all road conditions. When battery power is low, the DM-i system automatically determines whether to use electricity or fuel, or a combination of both, based on system operating conditions.
