汽车转向为什么会出现时沉时轻?

来源:http://www.sdjnltqf.com发布时间:2020-03-19 17:36:59

  一辆2009年东风本田cr-v,射程约13.8万公里,2.4升发动机和5档自动变速器。济南奔驰汽车保养客户抱怨转弯时总是很重的时候很轻,有时会有反弹力,偶尔会有“咔哒”声。
  A 2009 Dongfeng Honda CR-V with a range of 138000 km, 2.4-liter engine and 5-speed automatic transmission. Jinan Benz car maintenance customers complain that when cornering, it is always heavy and light, sometimes it has rebound force and occasionally "click".
  后车:先测试确认故障现象,发现转弯时确实是重时轻,但没有听到异常的声音,也没有经历过力的反弹。与客户再次尝试也未能复制异常的声音。接下来检查转向助力油杯的转向油位,发现刻度以下的更低线,此时转向泵漏油,并覆盖一层油性粉尘。在转向系统的其他部分没有发现异常,如舵机和助力管。由于客户投诉噪音异常,车辆被吊起来检查底盘,发现右前方的稳定杆拉杆球头有明显数量的开口,初步判断这是客户投诉噪音的来源。客户的同意,更换转向升压泵和稳定器杆面前,并将增压油添加到正常水平测试,发现转向仍重,光,和之前的变化差异不大,同时没有异常声音。

  After the car: first test and confirm the fault phenomenon. It is found that the turning is really heavy and light, but no abnormal sound is heard, and no rebound of force has been experienced. Trying again with the customer also failed to copy the abnormal sound. Next, check the steering oil level of the power steering oil cup and find the lowest line below the scale. At this time, the steering pump leaks oil and is covered with a layer of oily dust. No abnormality was found in other parts of the steering system, such as the steering gear and booster pipe. Due to the customer's complaint about the abnormal noise, the vehicle was lifted up to check the chassis. It was found that there were obvious number of openings in the front right stabilizer bar ball joint. It was preliminarily determined that this was the source of the customer's complaint noise. With the consent of the customer, replace the front of the steering booster pump and stabilizer bar, and add the booster oil to the normal level test. It is found that the steering is still heavy and light, which is not different from the previous changes, and there is no abnormal sound.
  经过与客户的沟通,我们了解到这辆车经常进出大厦。根据这一信息,考虑到现场恶劣的驾驶条件,转向系统的齿轮和齿条可能会有轻微的变形,导致转向重、轻。更换舵机试验,仍未改善。
  Through communication with customers, we know that this car often goes in and out of the building. According to this information, considering the poor driving conditions on site, the gears and racks of the steering system may have slight deformation, resulting in heavy and light steering. The test of replacing the steering gear has not been improved.
  但只有反复撞击转向试验转向系统。在原地慢慢向右转时听到“咔嗒”声。听诊器确认声音来自右前上方的阻尼。对右前减震解体检查,发现顶胶已被减震弹簧磨穿,更换右前减震顶胶,试验转向时不再下沉。
  But only repeated impact steering test steering system. "Click" when turning slowly to the right in place. The stethoscope confirms that the sound comes from the damping at the top right front. The right front shock absorber was disassembled and inspected. It was found that the top rubber had been worn through by the shock absorber spring. Replace the right front shock absorber top rubber, and no longer sink during the test steering.
