ssangyong musso 3.2 automatic 4x4 permanent nu inteleg cuplajul 4x4

[ciprian2001]

detin un ssangyong 3.2 automat ..este 4x4 permanent,,as vrea sa stiu cum este distribuita tractiunea,,si de ce atunci cand patineaza spatele se aude un zgomot(ca o vibratie), cupleaza fata si cateodata, daca doresc sa franez dupa ce a cuplat si fata 3,4 secunde nu am frane,,pedala se duce la fund,cum functioneaza acest sistem permanent la musso?

va multumesc

Banuiesc ca ai 4x4 permanent cu TOD. TOD este un sistem complex ce monitorizeaza in permanenta TPS, rotatia cardanelor, ABS, frana si pozitia cutiei automate.

 

 

FUNCTION DESCRIPTION

1. TOD System Select Mode (4H and 4L)

4H is the mode when drive normally of which gear ratio is 1 : 1 and 4L mode distributes power to front and rear

wheels 50:50 of which gear ratio is 2.48 : 1.

2. TOD System Function (select 4H mode)

TOD system controls clutch mechanism to comply with rotation in front and rear propeller shaft and if its difference

exceeds the permissible range, corresponding power is distributed into front wheel through EMC (Electro-Magnetic

Clutch).

Hall effect sensor signals speed on front and rear propeller shafts going through with TOD control unit.

Transfercase clutch coil is activated by variable current on exceeding difference of speed in front and rear propeller

shafts.

3. Function of 4L Mode

When select 4L mode, EMC is locked to apply maximum torque into front and rear propeller shafts. Shift motor

rotates also 4L position by rotation of cam thus propeller shaft torque changes from 1 : 1 to 2.48 : 1 by planetary

gear set.

4. Shift Motor

It locates backside transfer case, which drives rotary helical cam.

When mode select switch changes to 4L, shift fork is on position for 2.48 : 1 by rotation of helical cam.

5. Transfer Case

TOD transfer case distributes power into front and rear axle by operation of 4H/4L switch and shift motor.

Shifting 4H to 4L, is performed towards reducing HI-LO collar by means for connection HI-LO shift fork with

output shaft in order to join with planetary gear. Torque transmits input shaft then sun gear rotating front planetary

gear. Front planetary gear join with output shaft and drives LO position.

 

In privinta franei, cotrolerul TOD are o intrare pe pinul 26 de la intrerupatorul pedalei de frana iar pe pinul 25 de la ABS.

 

Banuiesc ca acest controler are o eroare.

 

Eu nu am Musso dar Andi te poate ajuta.

iti atasez documentatia pentru cutia de transfer TOD, in format PDF, te va ajuta.
