Mokhoa oa ho Lekola Brake ea Trailer ka Multimeter (Tataiso ea Mehato e meraro)

Limanete tsa brake tsa trailer tse fosahetseng kapa tse tsofetseng li ka baka mathata a tebileng ka ho emisa tereila hang hang. Mathata a mang a ka bonoa feela ka ho sheba li-brake magnets, empa ka linako tse ling ho ka ba le mathata a itseng a motlakase a amang mariki a tereilara ea hau.

Brake makenete e fosahetseng e ka etsa hore mariki a thekesele kapa a theohe kapa a etse hore mariki a hulele ka lehlakoreng le leng. Lena ke lebaka le lekaneng la ho utloisisa hore na tsamaiso ea hau ea braking e sebetsa joang le hore na u ka e lokisa joang haeba ho hlokahala. Mohato oa bohlokoa ka ho fetisisa oa ho utloisisa hore na mariki a k'haravene a sebetsa joang ke ho ithuta ho lekola mariki a trailer ka multimeter.

Ka kakaretso, haeba u batla ho lekola mariki a trailer ea hau ka multimeter, u hloka ho etsa joalo:

(1) Tlosa makenete a brake

(2) Beha setsi sa makenete ea brake holim'a terminal e fosahetseng.

(3) Hokela lithapo tse ntle le tse mpe.

Ka tlase ke tla hlalosa tataiso ena ea mehato e meraro ka botlalo.

Ho utloisisa hore na braking system e sebetsa joang

Ho na le mefuta e 'meli ea mantlha ea sistimi ea braking ea tereilara: mariki a trailer a impulse le mariki a trailer ea motlakase. Pele o ea tlhahlobo, o hloka ho tseba hore na koloi ea hau e na le mofuta ofe oa braking system. Ka tlase ke tla bua ka mefuta e 'meli ea litsamaiso tsa braking. (1)

• Mofuta oa pele ke li-trailer impulse brakes, tse nang le clutch e ts'oarellang e kentsoeng lelemeng la tereilara. Mofuteng ona oa brake ea trailer, braking e iketsa, ho bolelang hore ha ho hlokahale hore ho be le khokahanyo ea motlakase pakeng tsa terekere le tereilara, ntle le mabone a pele. Ka hare ho na le khokahanyo ho cylinder e kholo ea haeteroliki. Lebelo la pele la tereilara le sebetsa holim'a clutch ea tšireletso ea maqhubu neng le neng ha terekere e kenya mariki. Sena se etsa hore koloi e khutlele morao 'me e kenye letsoho ho master cylinder piston rod.
• Mofuta oa bobeli oa brake system ke mariki a motlakase a tereilara, a tsamaisoang ke khokahano ea motlakase ho brake pedal kapa switch e feto-fetohang ea inertia e kentsoeng deshebotong ea tereilara. Nako le nako ha ho kengoa mariki a motlakase a tereilara, motlakase o lekanang le sekhahla sa ho theoha o matlafatsa makenete ka har'a mariki ka 'ngoe. Makenete ona o etsa hore ho be le setena seo, ha se kentsoe, se tiisa mariki. Taolo ea mofuta ona e ka hlophisoa bakeng sa meroalo ea litereilara tse fapaneng.

Mokhoa oa ho lekola mariki a trailer ka multimeter

Haeba u batla ho lekanya mariki a tereilara ka multimeter, u lokela ho latela mehato e 3 e tobileng, e leng:

1. Mohato oa pele ke ho tlosa li-brake magnets ho tereilara.
2. Mohato oa bobeli ke ho beha motheo oa brake magnet sebakeng se fosahetseng sa betri.
3. Mohato oa ho qetela ke ho hokahanya mekhoa e metle le e mpe ea multimeter ho betri. U lokela ho hokela multimeter ho terata e putsoa e eang ka morao ea brake controller 'me haeba u hlokomela leha e le efe hona joale ho multimeter joale makenete ea brake e shoele' me e hloka ho nkeloa sebaka.

Ke khothaletsa hore u sebelise betri ea 12 volt ha u hlahloba tsamaiso ea brake 'me u lokela ho hokela terata e putsoa e laolang mariki ho multimeter ebe u e beha sebakeng sa ammeter. U lokela ho fumana boholo ba amp bala ka tlase.

Brake bophara 10-12

• 5-8.2 li-ampere ka mariki a 2
• 0-16.3 li-ampere ka mariki a 4
• 6-24.5 li-ampere sebelisa ka mariki a 6

Brake bophara 7

• 3-6.8 li-ampere ka mariki a 2
• 6-13.7 li-ampere ka mariki a 4
• 0-20.6 li-ampere sebelisa ka mariki a 6

Ke boetse ke u eletsa hore u sebelise tšobotsi ea ohmmeter ho multimeter ea hau ho lekola ho hanyetsa ha makenete ea brake.

Ho na le mefuta e itseng eo u lokelang ho e ela hloko ho li-brake magnets 'me mefuta eo e lokela ho ba pakeng tsa 3 ohms le 4 ohms ho itšetlehile ka boholo ba magnets ea hau, haeba sephetho se sa tšoane le sena joale brake magnet e senyehile' me e tla tlameha ho nkeloa sebaka. (2)

Ha u hlahloba mariki a k'haravene ea hau, ho na le mathata a motlakase a ka amang tsela eo mariki a hao a sebetsang ka eona, 'me u ka etsa tlhahlobo ea pono ho fumana hore na phoso e hokae tsamaisong ea hau ea mariki.

Tlhahlobo ea pono e hloka mehato e meraro ho fumana hore na ho na le bothata.

1. Mohato oa pele ke ho hlahloba setsi sa brake sa tereilara bakeng sa matšoao a mofuta ofe kapa ofe oa khoele. Haeba u e fumana, ho bolela hore e khathetse ’me e hloka ho nkeloa sebaka ka potlako.
2. Mohato oa bobeli ke ho nka rula eo u tla e beha ka holimo ho makenete. Moeli ona o lokela ho bapa le moeli o otlolohileng ka tsela eohle, 'me haeba u hlokomela phetoho leha e le efe kapa ho phunyeha ka holim'a makenete, sena se bontša ho apara ka mokhoa o sa tloaelehang' me o lokela ho nkeloa sebaka hang-hang.
3. Mohato oa ho qetela ke ho hlahloba makenete bakeng sa masala a mafura kapa oli.

Matšoao a brake e mpe ea tereilara

Ho na le litaba tse ling tseo u lokelang ho li ela hloko haeba u sa rate ho etsa liteko tsa mariki a trailer. Litaba tsena li bontša hore ka sebele u na le bothata ba mariki 'me u lokela ho etsa hore mariki a k'haravene ea hau a hlahlojoe hang-hang ho netefatsa. Mathata a mang ke ana:

• Bothata bo bong bo joalo ke brake e fokolang ea pele ea motlakase, haholo-holo haeba u na le mariki a motlakase mabiling a mane a tereilara ea hau. Boemong boo ntho e 'ngoe le e 'ngoe e sebetsang ka mokhoa o phethahetseng, karolo e chitja ea brake actuating lever e tlameha ho supa pele e le hore mariki a tereilara a sebetse hantle.
• Bothata bo bong bo hlaha ha u hlokomela hore tereilara ea hau ka tsela e itseng e hula ka lehlakoreng ha u kenya mariki. Sena se bontša hore braking ea tereilara ea hau ha e sebetse hantle.
• Bothata bo bong bo boholo ke ha u hlokomela hore mariki a k'haravene ea hau a notlela ho ea qetellong ea setopo. Ha u fihla moo u emang 'me brake ea hao e notlehile, bothata ke litlhophiso tsa "brake control unit". Ho ka etsahala hore ebe ho hanyetsa ha mariki ho phahame haholo, e leng se tla lebisa ho phunyeha le ho roala ha li-brake pads.

U ka sheba mona mokhoa oa ho lekola mabone a trailer ka multimeter.

Ho akaretsa

Ho lokela ho hopoloa kamehla hore mariki a litereilara a hloka ho lokisoa khafetsa ka lebaka la meroalo e boima e tsamaisoang ke likoloi tsena, ka hona ke tla u eletsa hore u lule u lekola mariki a tereilara ea hau ho qoba likotsi kapa likotsi tse teng tseleng ka lebaka la ho se be le braking e sa lokelang. litsamaiso.

Mathata a nang le lipotoloho tse khutšoanyane ka wiring a boetse a lebisa mathateng a tebileng. Lithapo tse tsofetseng kapa tse senyehileng li ka bakoa ke ho beha terata ka har'a axle ka boeona.

Haeba u bona molaetsa skrineng sa "brake controller" o reng "output shorted", o lokela ho qala ho batla mathata a lithapo ka har'a axle ea hau. Hape u lokela ho ba hlokolosi haholo ha u sebetsa ka lithapo le motlakase ho thibela ho tsosoa ke motlakase.

Lithuto tse ling tsa bohlokoa tseo u ka li shebang kapa tsa bookmark li thathamisitsoe ka tlase;

• Mokhoa oa ho lekola betri ka multimeter
• Mokhoa oa ho lekanya li-amps ka multimeter
• Mokhoa oa ho Sebelisa Multimeter ea Cen-Tech Digital ho Lekola Voltage
