Turbo-transmissions is a hydrodynamic link converting the mechanical energy of the motor into the kinetic energy of the fluid. This happens through the torque converter and the fluid coupling before the final rotary output is produced. The fluid passes through rotor blade canals. The flow rate is high at low pressure. This is how a turbo transmission differs from a hydrostatic transmission.
How does it work?
- The torque converter is the main unit of the turbo transmission.
- This mechanism is in high demand in diesel-powered vehicles.
- It shows a better startup performance, without affecting the dimension of the startup convertor and constant in transit loading of the travel phase converter.
- The single-stage converter using centrifugal flow turbine is the best amongst many different torque designs. Owing to its simple construction and radial stability of the turbine the convertor is well adapted to rpm operations.
In the 1970s the enhanced traction features were coming closer to the startup traction, the two-convertor transmission replaced the three-converter transmission. The quest for improving the torque convertors is continuous though they are quite advanced now.
Engineers are better informed of modern computational fluid dynamics (CFD) which gives them a clearer picture of rotating turbine wheel flow patterns at each grid intersection. It helps to calculate the flow volume, speed, and pressure.
Difference between normally aspirated transmission and turbo transmission
- The normally aspirated transmission and Turbo transmission can be both 5-speed transmission models with the same splines on input and out shafts.
- The housing of both the normally aspirated transmission and turbo transmission is mostly the same.
- The spot where the starter mounts on the bellhousing is machined differently engaging the slightly larger diameter flywheel which prevents the flywheel teeth from scraping the inside of the bellhousing.
- A normally aspirated transmission 5 speed can be
used in a turbo transmission with the use of a flat washer to make the
turbo transmission flywheel fit well.
Difference between transmission turbo 350 and turbo 400
- The turbo transmission is a hydrodynamic, multistage assembly drive that works on the principle of fluid dynamics.
- It includes torque converters, fluid converters and optional hydrodynamic retarders.
- This low torque transmission turbo 350 and turbo 400 are GM transmissions used from 1969 to 1990 in heavy vehicles.
- In light cars, a modified TH-350 was used as a high torque transmission.
- The TH 400 used in heavy cars operates on high torque and is a stronger transmission than 400.
- The TH 400 is placed on the right rear of the transmission.
- A kick-down cable differentiated the TH 350 from the TH 400.
- They were used in Chevrolet V-8 cars and light trucks.
- Both transmission pans have 13 bolts but with different shapes.
- A square pan cut from the corner distinguishes a TH-350 while a TH-400, uses an oblong-shaped pan and the pan sides have a hump, curved at one and straight on the other side. It is further identifiable with two circular indents on the humped side of the pan.
- The TH-400 measures 38 inches in length while the total length of TH-350 is 33 5/8 inches, this is when both use the longest available tail shafts. The body of the TH 400 measures 25 inches while the TH 350 is 21 5/8 inches.
- The TH-350 tail shafts are 6-, 9- or 12-inch long.
- The TH-400 tail shafts are 4-,9- or 13-inch long.
