Places of installation of system Dynamic-Ride-Control: 1 – a forward right amortisation rack; 2 – the forward right valve otkachki/fillings; 3 – line DRC to a forward right amortisation rack; 4 – the back right valve otkachki/fillings; 5 – the back right shock-absorber; 6 – line DRC to the back right shock-absorber; 7 – цетральный the valve for forward left and back right the parties; 8 – цетральный the valve for forward right and back left the parties; 9 – line DRC to the back left shock-absorber; 10 – the back left valve otkachki/fillings; 11 – the back left shock-absorber; 12 – line DRC to a forward left amortisation rack; 13 – the forward left valve otkachki/fillings; 14 – a forward left amortisation rack
|Fig. 4.39. The central valve and screw connections to amortisation racks: 1 – цетральный the valve for forward right and back left the parties; 2 – шестигранная a nut, 23 Н·м; 3 – запорный the valve to a back left line; 4 – запорный the valve to a forward right line; 5 – шестигранная a nut, 23 Н·м; 6 – запорный the valve to a forward left line; 7 – запорный the valve to a back right line; 8 – цетральный the valve for forward left and back right the parties; 9 – line DRC to the back right shock-absorber; 10 – line DRC to a forward left amortisation rack; 11 – line DRC to a forward right amortisation rack; 12 – line DRC to the back left shock-absorber; 13 – запорный the screw; 14 – a counternut, 12 Н·м
For connection and switching-off of the measuring device the checked line should be blocked on the central valve as much as possible to lower leak of oil and not to empty the central valve which is under pressure.
Before removal or a detachment of any components DRC necessarily block a corresponding line on the central valve. If at works on DRC to the open central valve there is even a small leak of oil in any case the subsequent check of pressure in system with comparison of the set and actual values is necessary. In case of understating of the minimum pressure replacement of the corresponding central valve is necessary.
Small leak of oil from connections at the closed central valve, occurring at joining / a detachment of the measuring device, is not critical. It is necessary to avoid repeated measurements since at each connection system leaves a few oils. At the subsequent connection it leads to pressure decrease approximately on 0,3 bar in comparison with the previous measurement. Thus the considerable quantity of measurements reduces pressure in system to minimum and more low up to a system exit out of operation.
Дэмпферы and pipelines as spare parts are delivered empty.
Filling is made only at a room temperature (nearby 20 °C).
Дэмпферы are filled only in the removed condition.
It is forbidden to put the car on wheels with the closed filled system and the blocked central valves. It will necessarily lead to leaks and a system exit out of operation.
Line do not bend.
