自动变速箱无超速挡故障的原因先容

发布日期: 2018-07-24 来源: / 点击:

自动变速箱无超速挡是指车辆在行驶过程中,车速已升高至超速挡工作范围,但自动变速箱不能从换入超速挡;或者是,在车速已经达到超速挡工作范围后,采用提前升挡,即松开油门踏板几秒后再踩下的方法也不能使自动变速箱升入超速挡。

Automatic transmission without overspeed gear means that the speed of the vehicle has risen to the overspeed range in the course of driving, but the automatic transmission can not be replaced by the overspeed gear; or, after the speed has reached the overspeed range, the method of lifting the gear in advance, that is, to release the accelerator pedal after a few seconds and then step down, can not change automatically. The speed box rises to the overspeed gear.
如您的车辆出现该故障,建议尽早将车辆送往的维修站点进行自动变速箱维修检查。
If your vehicle breaks down, it is recommended that the vehicle be sent to the professional maintenance station as soon as possible for automatic transmission inspection.
车辆到维修站点后,如车辆是电子控制的自动变速箱,应先对其进行故障自诊断,查看有无故障码(如有故障码,按显示代码查找相应故障)。变速箱油温度传感器、节气门位置传感器、超速电磁阀等部件的故障都会影响超速挡的正常使用。
After the vehicle goes to the maintenance site, if the vehicle is an automatic transmission of electronic control, it should first diagnose it and see if there is a fault code (if there is a fault code, according to the display code to find the corresponding fault). The failure of transmission oil temperature sensor, throttle position sensor and overspeed solenoid valve will affect the normal use of the overspeed gear.

其次需要检查变速箱油温度传感器在不同程度下的电阻值,并与标准值进行比较。如发现异常,应更换变速箱油温度传感器。
Secondly, we need to check the resistance of the transmission oil temperature sensor to different degrees, and compare it with the standard value. If abnormal is found, the transmission oil temperature sensor should be replaced.
档位开关和节气门位置传感器信号的检查也是必经流程。档位开关信号应与操纵手柄的位置相符。节气门位置传感器的电阻或输出电压应能随节气门的开大而上升,并与标准相符。如存在异常,应根据情况作出调整或更换。
The check of gear switch and throttle position sensor is also a necessary process. The gear switch signal should be in accordance with the position of the control handle. The resistance or output voltage of the throttle position sensor should rise with the opening of the throttle valve and conform to the standard. If there is an exception, it should be adjusted or replaced according to circumstances.
超速挡开关存在故障也会导致变速箱无超速挡。在ON位置时,超速挡开关的解点应断开,闭合超速指示灯不亮;在OFF位置时,超速挡开关触点应闭合,超速挡指示灯亮起。
The malfunction of the overspeed switch will also cause the gearbox to have no overspeed gear. At ON position, the solution point of the overspeed switch should be disconnected and the closed overspeed indicator is not bright; at OFF position, the overspeed switch contact should be closed and the overspeed indicator light rises.
针对此故障还需检查超速电磁阀的工作情况。打开点火开关,但不要起动发动机,在按下超速挡开关时,检查超速电磁阀有无工作的声音。如果超速电磁阀不工作,应检查控制线路或更换超速电磁阀。
For this fault, it is necessary to check the working condition of the overspeed solenoid valve. Turn on the ignition switch, but do not start the engine. Check the overspeed solenoid valve when you press the overspeed switch. If the overspeed solenoid valve does not work, check the control circuit or replace the overspeed solenoid valve.
