parameters
The MT86 mining dump truck is applied with the
countershaft and single case structure, which
is designed with seven forward gears and one
reverse gear without synchronizers. The
transmission realizes the gearshift via
sliding sleeve, and then the power
transmission through the engagement of the
external and internal splines on the gear with
the sliding sleeves.
The transmission is applied with two parallel
countershafts of same structure spaced from
each other by 180º. The power inputted from the
input shaft is diverted to the two counter
shafts and finally outputted via the output
shaft after converged. As two countershafts
only transmits 1/2 torque theoretically, the
center distance, gear width, axial size and
weight are reduced accordingly. Thanks to the
twin-countershaft structure, each gear on the
output shaft must be engaged with the two
countershaft gears simultaneously. In
