Simplified Explanation To Working Of Lock Up Torque Converters
Any car geek is always on the edge of their seats when it comes to technicalities of the mechanical block. One of the topics of interest that may add to the curiosity is the working of lock up torque converters. These converters have been a matter of interest for many owing to the fuel efficiency and better life of the transmission.
To know more on its working and the new lock up mechanism, read on.
Lock Up Torque Converters – From The Scratch
All the modern automatic transmission embedded models come with torque converter lockup. This is an innovative mechanism that is doing rounds in the market for the efficiency it offers. Let’s explore the basics and working of these systems from scratch.
1. What Is A Torque Converter?
Torque converters are similar to fluid coupling (device for passing rotating mechanical power) that holds the capability to transfer power from an internal combustion engine to the driven load. As far as the positioning is concerned, torque converters lie between the flexplate of the engine and the automatic transmission.
The basic function of torque converters is to multiply torque so as to cope up with the reducing rotational speeds. These converters prove to be a boon when it comes to driving a heavy vehicle down the road. Now that you know what a torque converter is; let’s move on with understanding lock up torque converters.

2. The Basics Of Lock Up Torque Converters
What is torque converter lockup? One should know the fact that a torque converter is susceptible to propelling loss in efficiency. When engine power is lower than a threshold normalized value, slippage inside a torque converter is liable to occur. With slippage comes heat which, in turn, leads to the loss of fuel economy. To do away with the underlying issues, a lock up clutch is thus introduced.
The innovative lock up system connects the impeller with the turbine, transforming the torque converter into an absolute mechanical coupling. The result of an implanted lock up mechanism includes improvement in gliding transmission power and less waste heat. You may also have a look at maintenance tips when better transmission speeds are all that you desire and how does a lockup torque converter work.
3. The Working Of Lock Up Torque Converters
A lock up clutch is engaged as soon as the engine and the transmission run at the same speed approximately. The speed at which a lockup mechanism automatically activates is about 64 kph. For transmission to lockup, however, some requirements follow.
Coolant temperature, lockup threshold speed, cruise control, and gears are some parameters that affect the functionality of lock up converters. If all the factors have fallen into place and the lock up activates, the impeller and the turbine hook-up. As a result, you can expect 100% power running through the torque converter. Isn’t it all that you want?
Wrapping Up
This is all about lock up torque converters that add overall life to automatics’ transmission. There are some issues related to poor lock up action too, that you must take into consideration. Before you diagnose any of the problems, understanding the working of lock up torque converters is necessary. This explains the hype around the topic!
