Lexus Automatic Transmission Troubleshooting the impact of l file

原文:
A Lexus 300 sedan, 3VE-FE engine type, transmission type for the A540E. Repair fault as follows: 1 block 2 block jump, it evidently felt that vibration, shock. While MULTI-FUNCTIONAL WATER PUMP CONTROL VALVE the other gear do not have this feeling, only to see the engine tachometer pointer jumping about. It reflects the owner of this gearbox overhaul just before, mileage less than 1600km. Overhaul time for the overhaul package accessories, manifold decomposition is also cleaned. Just complete a failure after some signs recently become increasingly evident.
The car's automatic transmission was developed by Toyota as a front drive Sidang electronically controlled automatic transmission, from the moment with a WATER POWER CONTROL VALVE locking clutch transmission device, the three planetary line-type Si Dang Simpson planetary gear transmission, electro-hydraulic control system, the composition of the main reduction gear and differential. This automatic transmission is characterized by: three planets and 10 row shift components are all mounted on a shaft, speeding planets arranged in row after row of the rear of the planet, spread the momentum from the planetary gear transmission speed planetary line Gear to pass on the final drive output gear driving shaft.
For troubleshooting, maintenance staff, the first pull to adjust their throttle and nothing happens. Shifting power to its solenoid valve, hydraulic shift them into the state, there is no response. Suspect that the internal potential problems are detected, then lift the disintegration of the next transmission to be checked. In a block jump 2 block, its shift components work as follows: low-gear one-way overrunning clutch release, two-way overrunning clutch block the work of two combination of block brakes. In addition, the FILTER SERIES direct one-way overrunning clutch, direct clutch, forward clutch block has been working in the 1,2 block. After examination, the internal clutch transmission film, sheet brake, the brake with both intact. Focus on examination of the work shift when the participation of two one-way clutch, the assembly there is no errors, one-way can also be locked. Check two block brakes and found a thick piece flange (steel) installed anti-a, the gap is too small. Consequently, they think may be due to gap junction is too small to make it too fast, resulting in shift generated when vibration, shock. Re-install readjust the gap, re-installed after the test, fault still exists.

一辆凌志300轿车,发动机为3VE-FE型,变速器为A540E型。报修故障为:1挡跳2挡时,明显感到震动、冲击。而其他挡位则没有这种感觉,只能看到发动机转速表的指针跳动一下。据车主反映,此变速器刚刚大修过,行驶里程尚不足1600km。大修时换了大修包配件,油路板也分解清洗过。刚修完后就有些故障征兆,近来越来越明显。
  该车的自动变速器是由丰田公司研制的一种前驱动四挡电子控制自动变速器,由带有锁止离合器的变速矩器、三行星排辛普森式四挡行星齿轮变速器、电液式控制系统、主减速器和差速器组成。这种自动变速器的特点是:3个行星排和10个换挡元件全都装在一个轴上,超速行星排布置在前后行星排的后部,传至行星齿轮变速器的动力由超速行星排齿圈上的输出齿轮传给主减速器主动轴。
  为排除故障,维修人员首先对其节流阀拉线进行调整,没有反应。对其换挡电磁阀断电,让其进入全液压换挡状态,也没有反应。怀疑其内部可能有毛病,于是抬下变速器解体进行检查。在1挡跳2挡时,其换挡元件的工作情况为:低挡单向超越离合器松开,2挡单向超越离合器工作,2挡制动器结合。另外,直接单向超越离合器、直接离合器、前进挡离合器在1、2挡一直工作。经检查,变速器内部的离合器片、制动片、制动带均完好。重点检查换挡时参与工作的两个单向离合器,装配上没有错误,单向也能锁定。检查2挡制动器,发现一个厚片法兰(钢片)装反了,间隙太小。于是认为可能是因间隙太小使之接合太快,造成换挡时产生震动、冲击。重新安装调整好间隙,装复后试车,故障现象仍然存在。
