Product Introduction

The transfer box adapted by our company is the transfer box

of 45-55 manufactured by Bogeguana, which is two-speed

and time driving, a set of planetary mechanism used is to

obtain the speed-reducing performance, while the driving

force is transmitted to the front driving gear by a highly precise

chain. The planetary gear train and rear output shaft element

of transfer box is lubricated initiatively through oil bath and oil

pump. This transfer box has four gears:

2H-stands for the two high gears

in which, only the two

rear wheel are driven, and the gear ratio of the transfer box

is 1:1

4H-stands for the four high gears, in which , all of the four

wheel are driven, and the gear ratio of the transfer box is

1:1

N- neutral location (this location only exists in the transfer

box of manual gearshift )

No driving force is transmitted

to the wheel when the input shaft and output shaft are

disconnected.

4L-stands for low gears, the four wheels are all driven, and

the gear ratio of transfer box is 2.48:1.

The gearshift of the mechanical gearshift transfer box is

obtained through the shifting-cam-type guide plate that is

operated by the shift rocker arm.

Sign board: which is fastened at the obvious external location

of transfer box, and on which the detailed data are marked.

Deceleration shift parts assembly

The mounting process is as follows:

(a)

If the parts are taken apart for change, assemble the shift

toggle fork assembly with a new pin-contact roller

assembly. Press the pin-contact roller in the deceleration

fork hole until the detent passes the hole completely and

seizes the right location. Ensure that the contact roller can

run freely.

(b)

Mount two inserted faces of toggle fork on the decelera-

tion toggle fork assembly.

(c)

Engage the deceleration fork assembly and deceleration

gear sleeve and put them in the housing, and the decelera-

tion gear sleeve shall be put in the planetary mechanism

assembly that is assembled already. Mount the rear

output shaft and joint the bearings at the ends of output

shaft and input shaft as well as the spline of the gear

sleeve.

Remarks: the output shaft assembly can be delayed until the oil

pump is mounted on the output shaft. The oil pump may be

dipped into the lubricant through the oil pump screen, turn the

output shaft in clockwise from the output shaft direction to see

whether there is lubricant pumped out so as to check whether

the oil pump can work normally or not. The parts mounted

readily may be encased in the transfer box housing as an

assembly

Oil pump assembly

Ensure the parts of oil pump are completely lubricated when

assembling, and the oil can be pumped out from the conical

hole of the oil pump front cover. The mount of oil pump is as

follows:

(a)

Mount the pin on the rear output shaft.

(b)

Slide the oil pump assembly on the rear output shaft

along with the pin.

(c)

Put the gripping hoop at the end of oil pipe that is

mounted on the oil nozzle of the pump housing, screw up

the gripping hoop.

Assembly of driving chain

The parts assembly process is as follows:

(a)

Put the driving chain sprocket at the rear end of the output

shaft, and the driven chain sprocket is put at the rear end

of the front output shaft on the worktable after the transfer

box housing assembly mount.

(b)

Mount the chain on the sprocket.

(c)

Holding the two chain sprockets parallel with the transfer

box in the space that the chain on the two sprockets are

straightened, and encase the chain and sprocket assembly

through the output shaft, it is required to run the chain

sprocket slowly to ensure that they engage with the front

output shaft and the spline.

(d)

Mount the gasket and snapping ring on the front output

shaft.

10. Shift locking element assembly

The parts mounting process is as follows (for the electric shift

transfer box):

(a)

Mount the return spring and locking hub on the locking

sleeve and fasten them with snapping ring to finish the

2W-4W locking sleeve assembly.

(b)

Encase the shift guide shaft in the blind hole of the

housing through the deceleration toggle fork assembly

that is already assembled.

(c)

Mount the shift toggle fork on the 2W-4W locking sleeve

assembly, which will slide through the shift guide shaft

and rear output shaft.

(d)

Joint the combined external gear sleeve spline and the

rear output shaft spline as well as the 2W-4W locking

sleeve.
