Transmission

Automated manual transmissions (AMTs) with dry clutches are becoming

more and more used as an improving add-on solution on classical manual

transmission systems and as a reconfiguration element in modern hybrid

electric vehicles. Due to the two possible states of the clutch (engaged or

not) and to the different gear ratios AMTs can be considered as a particular

class of the hybrid systems. The paper presents a gearshift control strategy

for modern AMTs. Models of the driveline, of an electrohydraulic

engagement actuator and of the dry clutch are detailed and tuned on

experimental data. The controller is designed through a hierarchical

approach by discriminating among five different AMT operating

conditions: engaged, slipping-opening, synchronization, go-to-slipping

and slipping-closing. Three cascaded feedback loops are designed

respectively on speeds, torques and throwout bearing position.

semi-automatic transmission is an electrohydraulic manual transmission

(aka sequential transmission). The gear set is almost the same as theconventional transmission system, except that the shifting of the selector is

not an 'H' pattern. Instead, all selector forks are connected to a drum (. The

drum has several grooves, and each has a ball sliding in it. Each fork hooks

up to a ball and can be moved forward and backward when the drum is

turning . Based on the pattern of the grooves on the drum, by turning the

drum, each fork can move forward and backward in turn, which makes

gear selection sequential. Therefore, it is impossible for an

electrohydraulic manual transmission to perform a gear shift from 1 stto

3rd or 4th to 2nd. The shifting must be sequential, like 1st'2nd'3rd'4th, or

4th'3rd'2nd'1st.

The transmission will be imported from Honda Motors as a spare part for

Honda Fourtrax Recon ATV.

The cost of the transaxle will be around Rs. 36000 including shipping

charges .

The clutch used will be ofWet-Multi Plate type which is well versed with

the transmission system.

The whole setup of transmission,mounting ,spares,miscellaneous can be

accounted as Rs.70000/-
