Hydros tatic Drive S ystem s for Road Rollers

In order to attain sm ooth road s urfaces s ealed

to an op timum level, a repeatable and reliable

precision is required for the s ealing function

carried out by road rollers.

A hydrostatic drive offers the bes t so lution for

this.

Axial piston units from Brueninghau s

Hydromatik are used for transmiss ion and

vibration drives, for additional devices, and in

addition they fulfil the required safety functions.

In addition to the axial piston pump s and motors

with the ass ociated control devices, including

electronics, the Rexroth group of companies is

able to supply al l other components, s uch as

gear pumps and m otors, radial piston mo tors,

valves, control devices, mechanical drives, etc.

The Mannesmann Rexroth group of companies

is ab le to offer a com plete solution for any drive

application. Why not talk to our road roller

sales department?

The quality of the Brueninghau s Hydromatik

products is along with the high level of

technologies the reason for content customers

worldwide.

The certification as to DIN ISO 9001 therefore

is the log ical result of our extensive quality

assurance strategy.

In order to ensu re reliable hydros tatic braking

and in o rder to prevent the motor from

overturning when reversing in un its, driven by

four hydraulic motors, a quadruple flow divider

should be installed for the transmission drive.

Safety functions

High pressure bypass(A4VG, A10VG)

Pos sible in all hydrostatic drives

No hydrostatic braking on

activating bypas s function

The bypass valve mus t be piped s eparately.

Pos itioning chamb er sho rt circuit

(A4VG, A10VG)

Very short return times po ss ible

Hydrostatic braking is

maintained

The bypass valve is mou nted directly

on to the pump.

Isolation of positioning pressure with

braking control (A4VG, A10VG)

Return time influenced to large

extent on l ine cross -sect ions.

Hydrostatic braking is maintained

The valve may be m ounted directly onto the

pum p. Calibration with respect to b rakerelease and return time of pump is requ ired.

Additional function for A4VG and

A10 VG with HW con trol:

Zero position s witch

It is used to disconnect vibration pump when

the roller is idle.
