t – ELASTIC COUPLING

Description

The t was designed for testing engines of commer-cial vehicles and heavy duty applications. This cou-pling is characterized by its low weight, high dampingand low maintenance requirements.

Naming

The product is named according to the following con-vention:

t -tttt-cccc-CVxxjoint sizedynamic stiffness [Nm/rad]nominal torque [Nm]series designation

Example: t650-2500-5200-CV21

Operating range

Torque: up to Nm

Speed: up to rpm

Benefits

■ weight optimized design

■ high damping

■ low maintenance

■ modular design

Function

As with all tectos products, the t follows a modulardesign principle, which separates the different func-tions.

The elastic part of the coupling is used to decouple anddamp the torsional vibrations.

The modular design consisting of a stable bearing car-tridge, the customer-specific adapter flange and theelastomer, allows assemblies with the most diversespecifications to be configured in a modular manner.

The standard t specifications cover a nominaltorque range of - Nm for a torsional stiff-ness of - Nm/rad.

t – STANDARD CLAW COUPLING

Description

The t standard claw coupling has been speciallydeveloped for use in motor sport, two-wheel applica-tions, and special applications, for example tests withdual mass flywheels or original vehicle clutches. Thiscoupling is characterized by its relatively low weight,very robust design, high damping capability and easymaintenance.

The development aim of this coupling (to transfervery high alternating torques at low stiffness) wasachieved in various designs.

t x – CV JOINT SHAFTS

Description

The t x series is a family of shafts with constant velo-city joints (CV joints). The various types are speciallyoptimized for their particular application. The designof a t x shaft is determined not only by the maximumtorque and the length, but also by the type of applica-tion. All shafts in this family offer a high level of longi-tudinal and angular compensation.

Naming


t x-CVyy-lllllength [mm]joint sizeseries designation

Example: t701-CV15-0303

Operating range

Torque: up to Nm

Speed: up to rpm

Benefits

■ outstanding vibration decoupling

■ low weight

■ integrated load-insensitive longitudinal compen-sation

■ precise concentricity

Function

The CV joint takes up the longitudinal, angular and axialdisplacement without adding any higher order speedor torque fluctuations to the drive train.

JOINT SHAFTS

t – CV JOINT SHAFT

The t is a CV joint bar shaft in a particularly com-pact and space-saving form. This design enables angu-lar and axial compensation in confined spaces. The barshaft is designed for optimum performance and manu-factured with high strength materials.

t – CV TUBULAR SHAFT

Due to its universal deployment capability, the tCV tubular shaft covers a wide range of standard appli-cations. Compared with the t bar shaft, its weldedtube allows longer installation lengths.

t – CV PRECISION TUBULAR SHAFT

The high quality, high precision t CV tubular shaftexhibits exceptionally precise concentricity with un-surpassed balance, due to its glued steel tube design.It is particularly suited for long installation lengths run-ning at high speed.

The t CV tubular shaft with a tube made fromcarbon-fiber reinforced plastic (CFP) is suitable forspecial motor sports and machine construction appli-cations. The use of carbon fiber provides high stiff-ness, but at low weight.

t – CV TUBULAR SHAFT GFR

The t tubular shaft with a tube made from glass-fiber reinforced plastic (GFP) is used predominantlyfor e-mobility applications. Due to the non-conductiveproperties of GFP, the two shat ends of the tare electrically fully separated from each other. Thismeans that the aggregate to be tested may be com-pletely decoupled from the test bed with regards toelectric and electromagnetic compatibility (EMC).

t – TORSION BAR SHAFT

Description

The t is a special shaft for use in highly dynamic ap-plications such as motor sports test beds. The shaftcomprises two CV joints and an encapsulated torsionbar, which runs on bearings inside a guide tube. It there-fore benefits from a very good relationship betweenbending frequency to torsional stiffness. The specialdesign allows low stiffness without having to compro-mise on the desirable high rotational speed.

The t is available in with CV joint sizes from CVto CV . Special designs are also available on request.

Each t shaft is tailored to customer requirements.

The t is also available as a t high-speed vari-ant.

If you need a t shaft for a certain speed, you shouldbe aware that the minimum length of the shaft is de-pendent on the torsional stiffness. This dependenceis represented in the following diagrams for for thetwo typical torsion bar materials: steel (left) and tita-

nium (right). The encapsulation in an aluminum tubeshifts the usual problems associated with the bend-ing frequency of a torsion bar into a much higher speedrange. That means the t shaft can be operated upto speeds of rpm.

tShaft – SHAFT SELECTION AND VERIFICATION TOOL

Description

When a new engine is to be tested in a test bed, it isalways a challenge to select a drive shaft with the cor-rect properties. It is important not only to transfer thecorresponding torque, but also to take into considera-tion the stiffness and distribution of the inertia values.

tShaft is a fast analysis tool which selects a driveshaft most suitable for a specific engine for a giventest cell. All current engine types can be defined withjust a few parameters. Integrated estimation algo-rithms are available for determining unknown quanti-ties.

The analysis is achieved with a non-linear torsionalvibration calculation. tShaft uses a shaft database,which contains details of all tectos drive shafts (e.g.t , t , t x and t x series, CV-shafts ofthe t x series and HK high-speed shafts of the t xseries in various sizes). Information on customer-specific components may be added to the database atany time.

Features

■ support of various engine types:in-line, V-type, boxer

■ estimation algorithms are provided for unavail-able parameters

■ modeling support for flywheels, dual-mass fly-wheels, clutches, quill shafts and transmissions

■ administration of several test beds

■ modeling of user-defined shafts

■ pre-selection of available drive shaft in a testfield

■ PDF reporting with torque and loss curves, for in-dividual shaft components

■ calculator to evaluate inertia and stiffness fromgeometric data

■ may be configured externally

■ maintenance-free

■ wear-free

FunctionTransceiver circuit board with power supply

Transceiver circuit board of the rotating side

Data logging board with DSP

Ferrite transmitter (for power supply)

With a bridge power supply of V, the DMS bridgesignals lie within a range of approx. ± mV. To pre-vent signal influences on this low voltage level, signalprocessing is done on the rotating side. To detect thesignals, -bit transformers with a sampling rate of

kHz are used. An integrated DSP (Digital Signal Pro-cessor) controls the conversion rate and produces thedesired output rate and resolution. The coupling of thedigital data with the CAN transceiver on the stationaryside is done optically. In addition to the measurementdata output, the transceiver may also be used for com-plete system configuration. Thanks to the touch-freeenergy transfer, the system is maintenance- and wear-free.
