Why Should Vibration Damping Panels Be Applied in Strips?

Applying vibration damping panels in strips can achieve better noise reduction effects. Here are the detailed introductions of vibration damping panels: 1. Installation method: First, remove the four-door trim panels and clean the dirt inside. Then apply the vibration damping panels on the metal sheet layer and press them firmly. Cover with a layer of sound insulation cotton, and apply the vibration damping panels on the trim panel layer as a whole. The door trim panels can be covered with sound insulation cotton or applied on the trim panel layer. Finally, reinstall the four-door trim panels. 2. Function: The function of vibration damping panels is to eliminate low-frequency vibration and noise bands caused by the metal sheet during idling or driving. The function of sound absorption cotton is to absorb medium and high-frequency noise bands generated externally or internally during driving.

What are the components of an electric vehicle powertrain system?

Electric vehicle powertrain systems include fuel cell engines, electric vehicle battery systems, on-board hydrogen supply systems, electric drive systems for power supply systems, and powertrain control systems. Below is an introduction to the electric power system: Components of the electric power system: Pure electric vehicles consist of three main parts: the electric drive system, the power source system, and the auxiliary system. The electric drive system includes the controller, power converter, electric motor, mechanical transmission device, and wheels. The electric motor functions similarly to the engine in a traditional car, with its primary task being to efficiently convert the electrical energy stored in the power battery into kinetic energy to drive the wheels under the driver's control, or to convert the kinetic energy from the wheels back into electrical energy during braking, feeding it back into the power battery to achieve braking energy recovery. The controller acts like the nervous system of the human body; electric vehicles must use a vehicle control system to coordinate and control various subsystems to achieve optimal overall performance. The power source system includes the battery pack and battery management system (BMS). The auxiliary system includes auxiliary power sources, power steering systems, air conditioning units, lighting devices, etc. Operation process of the powertrain system: Based on signals from the brake pedal and accelerator pedal, the electronic controller issues corresponding control commands to regulate the electric motor and adjust the power flow between the motor and the power source. The auxiliary power supply system mainly provides power for power steering, air conditioning, braking, and other auxiliary devices. In addition to signals from the brake and accelerator pedals, the steering wheel input is also a crucial signal. The power steering system determines the vehicle's agile steering based on the angular position of the steering wheel.

How to Move the Heel When Releasing the Clutch?

Move the heel slowly when releasing the clutch. Below are specific details about the clutch: 1. Meaning: The clutch refers to the separation device between the car engine and the transmission, also known as the clutch. In automatic transmission cars, the clutch is integrated into the transmission to achieve automatic shifting. 2. Principle: Since the engine needs to shift gears at different speeds, the driving part and the driven part of the clutch rely on friction between contact surfaces, use liquid as a transmission medium (hydraulic coupling), or use magnetic transmission (electromagnetic clutch) to transmit torque, allowing temporary separation and gradual engagement, while permitting mutual rotation during transmission. The torque generated by the engine is transmitted to the driven disc through the friction between the flywheel, pressure plate, and the contact surface of the driven disc. When the driver presses the clutch pedal, the diaphragm spring's large end moves the pressure plate backward through mechanical transmission, separating the driven part from the driving part. The engine's transmission device needs to deliver different speeds to the wheels at varying speeds, requiring the slow gear to be disengaged from the wheels and the high-speed gear to be engaged. This process of engagement and disengagement utilizes the clutch.

How to Release a Locked Handbrake?

Try fastening the seatbelt inside the car, starting the engine, shifting to D gear, and gently pressing the accelerator—the electronic handbrake will automatically release. Below is an introduction to electronic handbrake lock-up: 1. Introduction: Brake lock-up occurs when the wheels stop rotating due to strong braking force, but the car continues to slide forward due to inertia. 2. Prevention: Install a gear on the hub of each wheel's brake drum assembly, which drives a gear on the oil pump. The oil pump's outlet and inlet are connected to a hydraulic control valve. 3. Phenomenon: If the front and rear wheel tracks are not aligned, the car may skid. Once the wheels lock up, a sliding phenomenon occurs.

Why does the tire pressure monitoring suddenly display bar?

The display of bar indicates low tire pressure in the car, and it is necessary to check if the tire is leaking. Below is an introduction to bar-related content: 1. Conversion: Generally, car tire pressure is around 2.5bar, and 1bar equals 100kpa. 2. Unit: Common units for car tire pressure on vehicles are bar and kpa, and the tire pressure display is used to show the current tire pressure. 3. Lifespan: Both excessively high and low tire pressure can affect the lifespan of the tire. When the tire pressure is too low, the tire body expands, making the sidewalls prone to cracks. It also increases the tire's contact area with the ground, accelerating tire wear.
