汽车安全检查显重要,手刹如何自检保安全?

汽车手刹系统是保障汽车能平稳放车的一个重要保障!汽车手刹平时也有刹不稳的时候,遇到这些情况,车主首当其冲的就要检查汽车手刹,但如何检测汽车手刹是不是坏了呢?济南奥迪专修顾问教大家去了解!
Car handbrake system is an important guarantee to ensure the car can release smoothly! There are times when the handbrake is unstable. In these cases, the owner should check the handbrake first, but how to detect whether the handbrake is broken? Jinan Audi professional consultant to teach you to understand!
首先,确定手刹手柄的工作位置。与脚刹车的踏板一样,手刹手柄也有一个拉动的行程。通常规定,当手柄提拉到整个行程的四分之三时,手刹系统就应该处于正常的刹车位置了,所以在检查手刹的制动力之前,应该先找出这个工作点,这个工作点可以通过数棘轮的响声来确定。把汽车停在比较安静的地方,慢慢拉起手刹,边拉边数棘轮发出的“喀哒”声,直到手柄拉到尽头为止。然后算出响声总数的四分之三的位置,这个位置就是手刹手柄的有用工作点,可以用粉笔在手柄的滑轨上画上记号。
First, determine the working position of the handbrake handle. Like the foot brake pedal, the handbrake handle also has a pull stroke. It is usually stipulated that when the handle is lifted to three-quarters of the whole stroke, the handbrake system should be in the normal braking position. Therefore, before checking the braking force of the handbrake, we should find out the working point, which can be determined by counting the sound of the ratchet wheel. Park the car in a quiet place, slowly pull up the handbrake and count the "click" sound of the ratchet wheel until the handle is pulled to the end. Then calculate the position of three fourths of the total number of noises. This position is the useful working point of the handbrake handle. You can use chalk to mark on the slide rail of the handle.
接下来,就是检查手刹机构的效能。把汽车开到坡度较大、路面状况良好的斜坡上,踩住刹车,挂空挡(如果是自动变速则挂在N挡),将手刹手柄拉到刚才确定的工作点位置。然后慢慢松开刹车踏板,如果汽车没有发生滑动,就说明手刹的效能良好。由于制动器内存在间隙,有时在松开踏板后,汽车会轻微滑动,然后才停住,只要这个滑动的距离很小,手刹的效能也属正常。上坡和下坡应该各做一次。需要提醒的是,检查时要做好汽车发生滑动的准备,所以要注意周围的环境。
Next, check the performance of the handbrake mechanism. Drive the car to a slope with large slope and good road condition, step on the brake, shift to neutral (if it is automatic transmission, shift to n gear), and pull the handbrake handle to the working point just determined. Then release the brake pedal slowly. If the car doesn't slip, it means that the handbrake is effective. Because there is a gap in the brake, sometimes after releasing the pedal, the car will slide slightly and then stop. As long as the sliding distance is very small, the performance of the handbrake is normal. Uphill and downhill should be done once each. It needs to be reminded that the car should be prepared for sliding when checking, so pay attention to the surrounding environment.
除了制动效能外,还应该检查手刹的灵敏度,这对斜坡起步特别重要。在没有坡度的路面上慢速行驶,缓缓地提拉手刹手柄,感觉一下手柄的灵敏度和接合点。不过,这种检查方法会使手刹机构磨损,所以检查的次数不宜太多。
In addition to the braking efficiency, the sensitivity of the handbrake should also be checked, which is particularly important for starting on a slope. Drive slowly on the road without gradient. Slowly pull the handbrake handle to feel the sensitivity and joint point of the handle. However, this inspection method will wear the handbrake mechanism, so the number of inspections should not be too much.
