Symptoms of a faulty four-wheel drive coupler include poor acceleration, jerking during gear shifts, and sudden surges when accelerating. Below are related details: 1. Coupler: In microwave systems, it is often necessary to divide a microwave power signal proportionally into several paths, which is known as power distribution. The component that achieves this function is called a power distribution device or coupler, mainly including directional couplers, power dividers, and various microwave branch devices. 2. Four-wheel drive in vehicles: This refers to a driving form where the vehicle maintains four-wheel drive throughout the entire driving process, with the engine's output torque distributed to the front and rear wheels at a fixed ratio, ensuring excellent off-road and handling performance at all times. The four-wheel drive form is suitable for SUV models and off-road vehicles. Four-wheel drive forms are divided into three types: part-time four-wheel drive, on-demand four-wheel drive, and full-time four-wheel drive.
