      With o square feet of space dedicated to their torque converter business, ProTorque is a full-line manufacturing facility that produces tens of thousands of torque converters per year, from hard-to-find remanufactured import models up to the fully-custom Revolution Series converters that are found in many of today’s top runners. torque, depends on the speed ratio ν and the position of the guide blades. For torque converters according to the Föttinger design, the load-dependent hydrodynamic power transmission characteristic is reflected by the development of the turbine torque. The torque development corresponds to that of a .

The fluid coupling originates from the work of Dr. Hermann Föttinger, who was the chief designer at the AG Vulcan Works in Stettin. [2] His patents from covered both fluid couplings and torque converters.. Dr Bauer of the Vulcan-Werke collaborated with English engineer Harold Sinclair of Hydraulic Coupling Patents Limited to adapt the Föttinger coupling to vehicle transmission.

Additional Physical Format: Online version: Andersson, Sven A.E. On hydrodynamic torque converters. Lund, Sweden: Lund Technical University, Torque converters are often combined with gears either for start-up as in automotive gears or as possibility to branch off power, modulate the speed, and superimpose it via a revolving epicyclic gear.

Torque converters are described in VDItitled “Hydrodynamic power transmission; definitions, designs, mode of action” from April A torque converter is a type of fluid coupling which transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven a vehicle with an automatic transmission, the torque converter connects the power source to the is usually located between the engine's flexplate and the transmission.

The equivalent location in a manual transmission would be. Torque Converter Go Kart Clutch Set 3/4" Replaces Manco Comet TAV2 10T 40/41 and 12T 35 Chain Drive Belt.

Automatic transmissions of motor vehicles are generally equipped with hydrodynamic torque converters such as are described, for example, in EP-A 0 or EP-A 0or in the book by Gerigk, Bruhn & Danner, "Kraftfahrzeugtechnik", Westerman-Verlag, 2nd edition, pages Cited by: 3.

Key–Words: Hydrodynamic Torque Converter, Navier-Stokes Forces, Vane, Pump, Turbine 1 Introduction The flow within hydrodynamic torque converters is highly complex. Although a lot of numerical and ex-perimental efforts have been made to predict and an-alyse the flow in an automotive torque converter [1.

Introduction to Fluid Couplings Fluid couplings and torque converters are now commonly used in a wide variety of applications requiring smooth torque transmission, mostnotably inautomobiles. Theyusually consistof aninputshaft thatdrives a pump impellerwhich is closely coupled to a turbine impeller that transmits the torque of an output shaftFile Size: KB.

Hydrodynamic torque converters (hereinafter referred to as HDTC) are becoming increasingly widespread in motor vehicles. The book remains unique in its practical treatment of nonstationary. The torque transmitting capacity of any hydrodynamic coupling can be described by the expression () (), where is the mass density of the fluid, is the impeller speed, and is the impeller diameter.

In the case of automotive applications, where loading can vary to considerable extremes, r (n 2) (d 5) {\displaystyle r(n^{2})(d^{5})} is only an. Methods for analysis of general mechanical transmission systems with a hydrodynamic torque converter (HTC) are presented.

The methods are adapted for computer calculations. The properties of the HTC must be known, either explicitly as speed and torque characteristics, or implicitly as internal geometry (blade angles, etc.).Author: Anders Hedman.

Abstract. Hydrodynamic torque converters are commonly used in self-propelled vehicle transmissions. Torque converters are most efficient in trucks, haulers, tractors and other heavy and utility vehicles operating in variable road conditions and : N.

Trushin, V. Antsev, A. Obozov. Compared with the energy percentage amount of the first mode, the phenomenon was found that the vortex structure of the internal flow field became clearer with larger percentage amount.

Therefore, the existence of regular vortex structure is the major reason for Author: Qingdong Yan, Mingxing Huang, Wei Wei. A torque converter is a coupling that relies on a fluid hydrodynamic to allow the engine to spin independently of the transmission.

When the engine is idling, such as at a stop light, the amount of torque going through the torque converter is small, but still enough to require some pressure on the brake pedal to stop the car from creeping.

book Changing Gears [1] shows a Lysholm-Smith transmission with a torque converter and direct drive feature designed inwhich contains the basic functions of today's lock-up torque converters.

Torque converters of today look sim-ilar, but they have undergone continuous refine-ment through the years that have paralleled theFile Size: 2MB. Torque Converters – PARTS, REPAIRS, and Replacements.

Torque is a beautiful thing, and industrial torque converters are an impressive and sophisticated piece of equipment. If you’re just looking to get your hands on a replacement toque converter, we can help.

The torque converter provides a smooth automatic drive take-up from a standstill and a torque multiplication in addition to that provided by the normal mechanical gear transmission.

The performance characteristics of a hydrokinetic torque converter incorporated between the engine and the gear train is shown in Fig. for light throttle and full throttle maximum output conditions over a. Application of statistical formulas to hydrodynamic torque converter modelling Article in Archives of Civil and Mechanical Engineering 9(4)–48 December with 15 Reads How we measure.

use traditional torque converter clutch systems only in the upper gears. This means that the torque converter cannot be locked up to reduce losses when driving up a steep grade in first gear. The losses in the torque converters are converted into heat, so the "looseness" of the converter is restricted by the capacity of the cooling Size: KB.

Efficiency of the torque converter is also used to quantify performance and is the product of speed ratio and torque ratio. Figure 2 summarizes the typical hydrodynamic performance attribtues of K-factor, TR and efficiency as a function of SR.

At zero turbine speed (SR=0), referred to as stall, K-factor and TR are constant regardless of pump by: 1. torque ratio hydrodynamic drive with the maxi-mum torque ratio usually produced when the out-put shaft is stalled. The torque ratio falls off smoothly and automatically as the output shaft gains speed.

Unlike the simple straight radial blad-ing of the fluid coupling, the torque. Torque converters generate a large amount of heat, especially under acceleration Most transmissions send ATF fluid to the transmission cooler after it leaves the torque converter Most ATF coolers are located inside the radiator tank Vehicles used to tow trailers often require an additional ATF.TURBOdesign Suite is a unique aerodynamic and hydrodynamic 3D design package for all types of turbomachinery blades such as pumps, compressors, fans, turbines and torque converters.

TURBOdesign 1 TURBOdesign1 is an inviscid aerodynamic and hydrodynamic design software for turbomachinery blades using a 3D Inverse Design method.The invention relates to a hydrodynamic converter with a pump wheel, a turbine wheel and/or with guide blades.

2. Description of the Related Art. Hydrodynamic converters have long been known, see for example WO 02/14 A2 (=D1), U.S. Pat. No. 3, (=D2). Converters of this kind are usually interposed between an engine and a work machine.
