Brake Circuit (BK)

1 Kakaretso

Li-circuits tsa Brake li arotsoe ka mefuta e 'meli:laolwa jwaleleresistive voltage divider-controlled. Ka bobeli li na lekhanna lipotoloholeikopanye le lipotoloho tsa maikutlo.

1.1 Potoloho ea Brake e Laoloang Hajoale

• Sebopeho:

  • Khanna Potoloho: E tsamaisoa ke #79 kapa S420, e laoloang ke #LB contactor.

  • Feedback Circuit: Lipontšo tsa ho kopana le Brake (tse bulehileng / li koetsoe) li rometsoe ka ho toba ho liboto tsa W1 / R1.

• Tshebetso:

  1. #LB sehokahanyi se koala → Setsi sa taolo (W1/E1) sea sebetsa.

  2. Liphetho tsa yuniti ea taolo ea brake voltage → Brake ea bula.

  3. Mabitso a maikutlo a fetisa boemo ba lihlomo.

Sekema:

1.2 Resistive Voltage Divider-Laoloang ke Brake Circuit

• Sebopeho:

  • Khanna Potoloho: E kenyelletsa li-resistors tse arolang motlakase le mabitso a maikutlo.

  • Feedback Circuit: E beha leihlo boemo ba armature ka mabitso a NC/NO.

• Tshebetso:

  1. Brake e Koetsoe: Mabitso a NC a lihanyetsi tsa potoloho e khuts'oane → motlakase o felletseng o kentsoe.

  2. Brake Open: Armature e tsamaea → mabitso a NC a bulehile → Resistors e fokotsa motlakase ho isa boemong ba tlhokomelo.

  3. Maikutlo a Ntlafetseng: Tlatsetso HA HO mabitso a netefatsa ho koaloa ha mariki.

Ntlha ea bohlokoa:

• Bakeng saMechini e hohelang ea ZPML-A, ho lokisoa ha lekhalo la brake ho ama ka kotloloho maeto a lihlomo (ka nepo: ~ 2mm).

Mehato e 2 ea Kakaretso ea Tharollo ea Mathata

2.1 Ho hloleha ho sebetsa ka Brake

Matšoao:

• Brake e hloleha ho bula/ho kwala (mahlakoreng a le mong kapa ka bobedi).

• Hlokomela: Ho hloleha ha mariki ka ho felletseng ho ka baka ho thella ha koloi (kotsi e kholo ea polokeho).

Mehato ea Tlhahlobo:

1. Sheba Voltage:

   • Netefatsa pulse e felletseng ea motlakase nakong ea ho bula le ho lokisa motlakase ka mor'a moo.

   • Sebelisa multimeter ho metha voltage ea coil (mohlala, 110V bakeng sa #79).

2. Hlahloba Mabitso:

   • Fetola tokiso ea khokahano (bohareng bakeng sa taolo ea hajoale; haufi le pheletso ea leeto bakeng sa taolo e hanyetsanang).

3. Licheke tsa Mechini:

   • Lubricate likhokahano; etsa bonnete ba hore ha ho na litšitiso tseleng ea lihlomo.

   • Fetolasekheo sa brake(0.2-0.5mm) leselemo sa torquetsitsipano.

2.2 Liphoso tsa Letšoao la Maikutlo

Matšoao:

• Brake e sebetsa ka mokhoa o tloaelehileng, empa boto ea P1 e bonts'a likhoutu tse amanang le brake (mohlala, "E30").

Mehato ea Tlhahlobo:

1. Fetola Mabitso a Maikutlo: Teko ka likarolo tse tsebahalang tse ntle.

2. Fetola Boemo ba ho Kopana:

   • Bakeng sa taolo e hanyetsanang: Lokisetsa likhokahano haufi le pheletso ea leeto la lihlomo.

3. Sheba Wiring ea Signal:

   • Netefatsa ho tsoela pele ho tloha ho mabitso ho ea ho liboto tsa W1/R1.

2.3 Liphoso Tse Kopantsoeng

Matšoao:

• Brake action failure + liphoso tsa khoutu.

Tharollo:

• Etsa phetoho e feletseng ea brake u sebelisa lisebelisoa tse kangZPML-A Brake Calibration Device.

3 Liphoso Tse Tloaelehileng & Litharollo

3.1 Brake e hloleha ho buloa

3.2 Torque ea Braking e sa lekaneng

4. Litšoantšo

Setšoantšo: Brake Circuit Schematics

• Taolo ea Hona Joale: Topology e nolofalitsoeng e nang le litsela tse ikemetseng tsa ho khanna / maikutlo.

• Taolo e Hanyetsang: Li-resistors tsa ho arola motlakase le likhokahano tse ntlafalitsoeng tsa maikutlo.

Lintlha tsa Tokomane:
Tataiso ena e tsamaisana le maemo a lifti a Mitsubishi. Kamehla latela liprothokholo tsa polokeho 'me u shebe libuka tsa botekgeniki bakeng sa lintlha tse ikhethileng tsa mohlala.
