Driveline Angularity Úrræðaleit

snúningsvægi Titringur

Athugar Driveline U-sameiginlegan rekstur Angles

Aðgerðin á Driveline með hjörulið á hvorum enda vinna í gegnum hornið úrslit í sérkennilegri hreyfingu. The Driveline mun flýta og hægja tvisvar fyrir hverja byltingu. Ef vinnandi hornin á hvorum enda skaftsins er ójöfn, snúningsvægi titringur niðurstöður. Þetta snúningsvægi titringur mun hafa tilhneigingu til að hætta sér út ef báðir samstarfs- horn eru jafnir.

Tegundir Noise

Hávaða eða titring sem gerist aðeins á ákveðnum hraða á vegum og minnkar og eykst hraðinn er yfirleitt af völdum ójafna vinnuskilyrði hliðar- Driveline liðum. Hávaði eða titringur, sem er þrálát á hraðasviðið og er breytilegt hvað varðar styrkleika með breytingu á hraða getur stafað af ójafnvægi drivelines, ójafnvægi bremsa skálar eða diskar, eða drivelines með hjörulið út úr fasa.

forprófanir

Gera eftirlit með eftirfarandi áður en horn lesefni:

1. Check companion flange or yoke nut for looseness and torque to proper specification if necessary.
   
2. Driveline slip joints that do not have the arrows or other markings pointing to each other will result in the driveline universal joints being out of phase. Með öðrum orðum, the transmission universal joint may be turned one spline or more to the right or left of being aligned with the universal joint at the opposite end of the driveline.
   • Some computer designed drivelines are purposely built with U-joints out of phase. Check manufacturer’s specifications for proper setting. einnig, check closely to make certain no twist has occurred to the tubing, causing these two joints to be out of phase Make sure the slip joint works freely and is not bound or seized. Slip joints must absorb axle housing movements.
3. Unbalanced drivelines can cause vibration that occurs throughout the speed range of vehicle and varies in intensity with a change of speed. The driveline may be at fault in respect to balance and concentricity. A quick field check to determine driveline balance can be made by securing a small piece of metal or similar weight with a hose clamp to the front of the tube where the splined shaft is welded. Road test the vehicle and continue to move the weight around the tube until the balance point is found and vibration disappears or is minimized.
   
   Drivelines eru mjög virk í jafnvægi við hverfi hraða þeirra, sem og að óendanlega hraða. Þannig, vibration can be expected when this rotational velocity is exceeded. Check concentricity of driveline by mounting on lathe centers and dial indicating. Athuga upplýsingar framleiðanda um runout vasapeninga.
4. Vél styður sem borinn, brotinn eða laus, and mounting pads that are worn or deteriorated must be corrected to restore the engine suspension to its original vibration tolerance.

taka lestur

Ef titringur kemur í notkun tóm, take readings in empty condition. Ef það gerist þegar hlaðinn, take readings when loaded. When it is necessary to measure driveline lengths, measure from joint center to joint center

forskriftir framleiðandans skal fylgt þegar fyrstu angularity athuga. Some manufacturers have found it necessary to vary from the ideal due to geometrical limitations. If vibration persists after adhering to manufacturer’s specifications, contact the manufacturer’s representative.

Angularity Eftirlit - Parallel Múffur eða veldissprota

1. Einn afturás Ökutæki
   • sending horn – Take reading of transmission angle. This angle is the angle to which the rear axle joint angle must match. The transmission angle will have a declination reading of from 0 að 5 gráður í flestum tilfellum.
     
   • axle horn. Take reading either from machined surface of axle housing or pinion bearing retainer. This angle must be within one degree of the transmission angle.
     • Example: If transmission angle reading is 3 degrees down to the rear, the rear axle angle should be 3 gráður upp.
2. Tandem Ásar eða Ökutæki aukabúnaður
   • Taka sending horn lestur.
   • Take reading from joint of front tandem axle or auxiliary joint. This reading should be within one degree of transmission angle.
     • Note: The rear joint of front tandem axle will be the same as the front joint.
   • Taka lestur sameiginlega horn á Tandem afturás, or axle to rear of auxiliary. This angle must be within one degree of transmission angle.

Sameiginlegar Vinna Horn Limits (samhliða)

Hjöruliður með hámarks vinna horn, eftir gerð og framleiðslu. Það er mælt með því að sameiginleg vinna horn fyrir samhliða sameiginlega samkoma ekki yfir 8 gráður til helstu drivelines yfir 40″ Langt. Fyrir helstu drivelines undir 40″ hámarks horn ætti ekki að vera meiri en þjóðar (L) deilt með 5. (Þessi takmörkun gildir ekki um interaxle drivelines.)

Example: For A 35″ Driveline, the maximum joint working angle would be 35 plús 5 eða 7degrees. This working angle must not be exceeded.

Place protractor on driveline to obtain angle of driveline from transmission to axle. The difference between the driveline angle and the joint angle is the joint working angle. For instance, ef sending er 3 gráður niður, and the driveline angle is down 7 gráður, the transmission joint working angle is 7 mínus 3 eða 4 gráður.
On takt drif eða aðildarfélaganna innsetningar, take readings in the same manner, comparing the universal joint angles to the driveline angle to which it is attached.

Angularity Checks – Non-Parallel Compensating Angles or Flanges or Yokes

Með Tandem drifásar, the rearward axle is tilted upward until its pinion shaft centerline and forward axle pinion shaft centerline intersect midway between joint centers.

Þegar vangaveltur ósamhliða sameiginlegar innsetningar, it is necessary to take the driveline angle readings as well as transmission and axle angle readings.

1. Einn afturás Ökutæki
   • Taka horn lesa sending
   • Taka horn Driveline
   • Taka horn lesa sameiginlega ás
   • Að reikna fyrir rétt horn:
     • The difference between the driveline angle and the transmission angle will be the transmission joint working angle.
     • The difference between the driveline angle and the axle angle will be the axle joint working angle.
     • The two working angles of transmission and axle must be equal.
     • Example:
       sending er 3 gráður niður
       Driveline eru 7.5 gráður niður
       Afturáss er 12 gráður niður
       Þannig 7.5 mínus 3 jafnt 4.5 gráður
       12 mínus 7.5 jafnt 4.5 gráður, giving 4.5 equal working angles
2. Tandem Ásar eða Ökutæki aukabúnaður – When taking readings on tandem drive axles or between auxiliary and rear axle, the same principles apply as with single axle vehicles. Take readings between transmission and front tandem axle, or auxiliary. Take readings between axles or between auxiliary and axle. Með öðrum orðum, take angle readings for each set of universal joints

Sameiginlegar Vinna Horn Limits (Non-Parallel)

Það er mælt með að hámarks sameiginlegt vinna horn fyrir utan samsíða sameiginlegum þingum ekki yfir helstu Driveline lengd deilt með 10. Til dæmis, ef helstu Driveline lengd er 55, hámark sameiginlegt vinna horn er 55 deilt með 10 eða 5.5 gráður. (Þessi takmörkun gildir ekki um interaxle drivelines.)

ása Leiðréttingar

Ása horn má almennt stillt með einni af eftirfarandi leiðum, eftir því hvaða gerð af ás.

1. Stilla togi stöfunum, ef stillanlegum gerð.
2. Add to or reduce length of non-adjustable torque rods.
3. Add or reduce the number of shims behind torque rod brackets.
4. Use correct amount of wedge shims under spring to axle pad.
