Definitions
- the present invention is related to the technical field of mechanics, specifically the automotive industry, since it provides a tool to retain, measure and compare various variables of a torque converter, within a production line, in order to validate at the moment the established specifications.
- the torque converter is known by various names, such as hydrodynamic torque converter and Föttinge converter since the principle of the torque converter was applied for the first time by Hermann Fóttinger, in 1905, in shipbuilding.
- the torque converter is a mechanism that is used in automatic transmissions to replace the clutch, and makes the connection between the gearbox and the engine. In this system there is a connection between the crankshaft and the primary gearbox shaft, which takes advantage of the centrifugal force that acts on a fluid (oil) located inside the converter.
- the torque converter may have a clutch torque converter known as a TCC, which may include a torsional damper and a friction clutch actuated hydraulically by the same fluid.
- impeller Also known as impeller.
- This element has blades that are responsible for driving the oil to the turbine. It is considered the conductive element, because it is the one that receives the movement of the motor, to which it is attached, and drives the oil against it.
- the impeller is attached to the flywheel of the engine and the turbine is attached to the input shaft of the transmission. When the engine is started, the impeller begins to rotate and pushes the oil from its center to the outer edge.
- Turbine The driven element is called a turbine, and it is coupled to the gearbox.
- the pump part of the torque converter directs pressurized oil against the turbine to make it turn.
- the turbine is connected to a shaft, to transfer power to the transmission. Its mission is to receive the oil sent by the driver.
- the turbine rotates together with the output shaft since they are joined on the same shaft.
- the torque converter includes a third element that improves the operating conditions in the oil circulation, it is the stator. Its function is to redirect the oil occupied by the turbine and deliver it to the impeller, it changes the direction of the oil flow, this allows to increase the impulse of the oil. Inside the stator is a one-way bearing, which allows it to only rotate in one direction. The stator is used to redirect the flow from the turbine back to the pump part, to complete the oil flow. It is mounted on a freewheel mechanism that allows it to move freely when the elements of the converter rotate at approximately the same speed.
- Output shaft It is connected by splines to the turbine and sends the torque to the input shaft of the transmission.
- the output shaft is connected to the transmission by a yoke and drive shaft or directly to the input gear of the transmission, receives the force from the turbine and delivers it to the input shaft of the transmission.
- Hydraulic oil It is the element that produces the movement of the internal components of the converter, in addition to damping any vibration from the engine before it passes to any part of the transmission.
- Torque converters that are welded closed are used in light duty vehicles (cars and pickup trucks) and some medium duty vehicles, while heavy duty on-highway and off-highway trucks generally employ models. of torque converters that are bolt-on. This feature allows the torque converter to be disassembled and serviced when necessary.
- torque converter Like any auto part, if the torque converter does not meet the variables within the established specifications, it can cause a major failure in the operation of a car; This is why various tools or devices have been developed to measure various variables and validate the correct manufacture of torque converters.
- AUTOMATIC TRANSMISSION * which describes a torque converter interior space measurement apparatus for an automatic transmission that conveniently and simply measures a torque converter interior space change without disassembling the torque converter when initially assembling a torque converter.
- automatic transmission and is tested so that errors in the automatic transmission are capable of being corrected, thus improving the reliability of a product.
- a shaft is positioned in a longitudinal direction in a rod-shaped main body of the measuring apparatus.
- a circular handle mounted on an upper part of the main body and a collar mounted on a lower part of the main body are configured to interconnect by means of the shaft.
