自动变速器的阀板及换档实行元器件故障

发布日期: 2021-05-19 来源: / 点击:

手动式换档试验就是说将电机控制自动变速器全部换档电磁阀的整车线束电源插头所有脱开,这时ECU不可以根据换档电磁阀来操纵换档,自动变速器的换档在于变速杆的部位。不一样车系的电机控制自动变速器在脱开换档电磁阀整车线束电源插头后挡位和变速杆部位的关联不一致。

Manual shift test means to disconnect all the harness power plugs of all the shift solenoid valves of the motor controlled automatic transmission. At this time, ECU can not operate the shift according to the shift solenoid valve. The shift of the automatic transmission depends on the position of the shift lever. When the power plug of the whole vehicle harness of the shift solenoid valve is disconnected, the correlation between the gear and the shift lever of the motor controlled automatic transmission of different vehicle lines is inconsistent.
手动式换档试验的目地是明确常见故障存有的位置,区别常见故障是由机械设备、液压传动系统還是由电子器件自动控制系统造成的。手动式换档试验应在载入故障码和进行自动变速器基础查验后开展。
The purpose of manual shift test is to identify the location of common faults and distinguish whether the common faults are caused by mechanical equipment, hydraulic transmission system or automatic control system of electronic devices. Manual shift test shall be carried out after loading fault code and basic inspection of automatic transmission.

手动式换档试验的流程以下:
The process of manual shift test is as follows:
①脱开电子器件操纵自动变速器的全部换档电磁阀整车线束电源插头。
① Disconnect all shift solenoid valves of automatic transmission operated by electronic devices and the power plug of vehicle harness.
②启动柴油发动机,将变速杆拨至不一样部位,随后做路面试验(还可以将主动轮悬在空中,开展台架试验)。
② Start the diesel engine, shift the gear lever to different positions, and then do the road test (the driving wheel can also be suspended in the air to carry out the bench test).
③观查汽车转速和时速的对应关系,以分辨自动变速器所在的挡位。不一样挡位时汽车转速与时速的关联可参照下面的图。因为液力变矩器的降速功效与传送的转距相关,因而表格中时速只有做为参照,具体时速将伴随着行车中节气门油管压力的不一样而造成的转变。
③ Observe the corresponding relationship between vehicle speed and speed per hour to distinguish the gear of automatic transmission. The relationship between vehicle speed and speed per hour in different gears can be seen in the following figure. Because the deceleration effect of the hydraulic torque converter is related to the transmitted torque, the speed per hour in the table can only be used as a reference, and the specific speed per hour will change with the different throttle oil pipe pressure during driving.
④若变速杆坐落于不一样部位时,自动变速器所在的挡位与图中中列出同样,则表明电子器件操纵自动变速器的阀板及换档实行元器件大部分工作中正常。不然,表明自动变速器的阀板或换档实行元器件有常见故障。
④ If the shift lever is located in a different position and the gear of the automatic transmission is the same as that listed in the figure, it indicates that the electronic devices operate the valve plate and gear shift of the automatic transmission and most of the components work normally. Otherwise, it indicates that there is a common fault in the valve plate or shift actuator of automatic transmission.
⑤试验完毕后,接好电磁阀整车线束电源插头。
⑤ After the test, connect the harness power plug of solenoid valve.
⑥消除电脑上中的故障码,避免因脱开电磁阀整车线束电源插头而造成的故障码储存在电脑上中,危害自动变速器的常见故障自确诊工作中。
⑥ Eliminate the fault code in the computer, avoid the fault code caused by disconnecting the power plug of the whole vehicle harness of the solenoid valve to be stored in the computer, and endanger the self diagnosis of common faults of the automatic transmission.
