一、车辆情况:维修时间:2019年12月4日,客户:梅州蔡先生,车型:日产轩逸,变速箱:CVT无级变速箱,行驶里程:15万公里。

1、 Vehicle condition: maintenance time: December 4, 2019, customer: Mr. Cai, Meizhou, model: Nissan Xuanyi, transmission: CVT continuously variable transmission, mileage: 150000km.
二、故障现象:入D档、2档换3档、3档换4档时都有明显的冲击感。
2、 Fault phenomenon: there is an obvious impact feeling when entering gear d, changing from gear 2 to gear 3, and changing from gear 3 to gear 4.
三、变速箱故障:师傅经过试车和检查,初步判断是阀体滑阀卡滞,电磁阀工作不良,离合器泄压或间隙不正常。
3、 Transmission failure: after test run and inspection, the master preliminarily judged that the valve body slide valve was stuck, the solenoid valve worked poorly, and the clutch pressure relief or clearance was abnormal.

四、变速箱维修:
4、 Transmission maintenance:
1、此车故障灯亮,用仪器读取故障码,变速箱控制单元故障:变矩器涡轮速度信号电路故障;更换了输入传感器,并检查线束后,试车故障依旧。
1. The fault light of the vehicle is on, the fault code is read with the instrument, the transmission control unit is faulty: the speed signal circuit of the torque converter turbine is faulty; After replacing the input sensor and checking the harness, the test run fault remains.
2、放出少许波箱油,有点儿糊味。抬下波箱,全部分解后,发现问题:胶圈老化、离合器油环位磨出台阶、摩擦片烧蚀、个别滑阀卡滞。
2. Release a little wave tank oil, a little paste smell. After lifting down the wave box and completely decomposing, problems are found: rubber ring aging, worn steps of clutch oil ring, friction plate ablation, and individual slide valves are stuck.
3、更换小修包,摩擦片,离合器古等配件后,彻底清洗阀体,反复测试电磁阀,测量各组摩擦片间隙,均在标准值内。复装试车,故障排除。
3. After replacing the minor repair kit, friction plate, clutch and other accessories, thoroughly clean the valve body, repeatedly test the solenoid valve, and measure the clearance of each group of friction plate, which are within the standard value. Reassembly and commissioning, troubleshooting.
