Sub-electric four-wheel trucks have brought us a lot of help in this energy-saving and environmentally friendly social environment. No matter what type of transportation tools are used, in order to ensure their own safety, they need to test the brake system. Today, the editor gives us What you brought is the test method for this type of electric vehicle, and I hope it can help you.

We all know that one of the most important systems in electric vehicles is handbrake detection. Like the pedal of the foot brake, the handbrake handle also has a pulling stroke. It is usually stipulated that when the handle is pulled to 70% of the entire stroke, the handbrake system should be in the normal braking position, so before checking the braking force of the handbrake, you should find out this 70% working point, which can be passed Count the ratchet sounds to determine.

During the test, park the electric vehicle in a relatively quiet place, slowly pull up the handbrake, and count the ratchet clicks while pulling until the handle is pulled to the end. Then calculate the 70% position of the total number of sounds, this position is the effective working point of the handbrake handle. Drive the electric vehicle to a slope with a large slope and good road conditions, step on the brake, put in neutral, and pull the handbrake handle to the position of the working point just determined. Then slowly release the brake pedal. If there is no slippage, the handbrake is effective. Due to the gap in the brake, sometimes after releasing the pedal, a slight slip occurs and then stops. As long as the sliding distance is small, the effectiveness of the handbrake is normal. Uphill and downhill should be done once.

The above content is the detection method of the brake system of electric four-wheel trucks. I hope it can bring you some help. If you want to know more product information, You can follow the official website of Qingzhou Hongri Vehicle Co., Ltd.
