3.Cara Kerja Differentiala) Saat Jalan LurusPada saat gesekan roda kiri dan roda kanan sama besar, maka differential case, pinion

gear dan side gear merupakan satu unit (differential pinion, differential side gear dan shaftberputar satu unit secara bersama-sama dengan ring gear) sehingga pada saat differential caseberputar, sidegear akan berputar dengan arah dan besar putaran yang sama, pada saat ini

pinion gear tidak berputar pada porosnya akan tetapi hanya berputar bersama-sama dengandifferential case. Akibatnya poros roda belakang akan berputar searah dengan putaran sidegear.

a) When the Straight PathAt the time of the friction wheel left and right wheels the same size, then differential case, pinion

gear and side gear is a single unit (differential pinion, differential side gear and the shaft rotates one unit

simultaneously together with the ring gear) so that when the rotating differential case, side gear will

rotate with the direction of rotation and the same, at this time pinion gear is not rotating on its axis but

only rotates together with the differential case. As a result, the rear wheel axle will rotate in the

direction of rotation side gear.

b) Pada saat membelok kekananDrive pinion memutarkan ring gear, ring gear memutarkan diffrensial case, diffrensial case

menggerakan pinion gear melalui pinion shaft dan pinion gear memutarkan side gear kirimengitari side gear kanan karena tahanan roda kanan lebih besar sehingga menyebabkanputaran roda kiri lebih besar dari roda kanan

c) Pada saat membelok kekiriDrive pinion memutarkan ring gear, ring gear memutarkan diffrensial case, diffrensial case

menggerakan pinion gear melalui pinion shaft dan pinion gear memutarkan side gear kananmengitari side gear kiri karena tahanan roda kiri lebih besar sehingga menyebabkan putaran

roda kanan lebih besar dari roda kiri

b) At the time of turning to right

Rotating the ring gear drive pinion, ring gear rotate diffrensial case, move the pinion gear diffrensial

case through the pinion shaft and pinion gear side gear rotating around the left side the right gear

for the right wheel is greater resistance thus causing rotation of the wheel left greater than right

wheel

c) When turning left

Rotating the ring gear drive pinion, ring gear rotate diffrensial case, move the pinion gear diffrensial

case through the pinion shaft and pinion gear rotating around the right side gear side gear wheels

left because of custody left greater rotation of the wheel, causing a greater right than the left wheel

Fungsi diffrensial :

Mereduksi kecepatan yang diterima dari propeller shaft untuk menghasilkan momen yangbesar.

Merubah arah putaran 90` ,selanjutnya putaran ini diteruskan keroda belakang melalui porosbelakang ( gear axle shaft ) secara terpisah.

Membedakan putaran roda kiri dan roda kanan pada saat membelok atau terjadi gesekan yangberbeda pada kedua roda belakang.

Komponen diffrensial :

Nut dan washer berfungsi untuk mengikat com panion flange terhadap drive pinion DRIVE PINION COMPANION FLANGE berfungsi untuk memindahkan tenaga putar dari propeller

shaft ke drive pinion

Oil seal berfungsi untuk mencegah kebocoran oli dari diffrensial Ring gear berfungsi menerima putaran dari drive pinion melalui perkaitan gigi, sehimgga

Diffrensial function:

Reduce speed received from the propeller shaft to produce a great moment.

Changing the direction of rotation 90 `, the next round keroda are relayed back through the rear

axle (gear axle shafts) separately.

Distinguish the wheels left and right wheel when turning or going on a different friction on bothrear wheels.

Diffrensial components:

Nut and washer serves to bind the com panion flange of the drive pinion

DRIVE FLANGE COMPANION pinion serves to transfer torque from the propeller shaft to the

drive pinion

Oil seal serves to prevent leakage of oil from diffrensial

The advantage with a tilt gear

The surface of teeth more contracts

The sound is more subtle

Shift more power

Wear and tear for longer

Losses in the form of slanted gears The price is more expensive

Efficiency less

Soal :

Sebuah kendaraan mempunyai differential dengan jumlah gigi pada

drive pinion adalah 15, dan pada ring gear adalah 60. Berapakah gear

ratio differential, torsi pada roda jika torsi pada propeller shaft 20 kg.m,

putaran pada roda sebelah kiri jika putaran propeller shaft 1000 rpmdan putaran pada roda kanan 100 rpm ?

GR = 60 = 4

15

Torsi roda = 4 x 20 = 80 kg.m

Rpm = 1000 = 250 rpm

4

Rpm roda kiri = rpm totalrpm roda kanan = 500100 = 400 rpm

Road Speed

V = Rpm x 2

6

R x 60

1000 x TR x AR

Dimana :

V= Road speed (km/jam)

Rpm = Putaran mesin

R

= Jari-jari ban (m)AR

= Gear ratio differential

TR

= Gear ratio transmisi
