Fourth gear splined hub G25, third gear driven gear G24 form three fourth gear switching modules.
Working principle is as follows:
One or two gear shift principles: one or two grades of clutch collar J1 are in an intermediate position, realize the neutral gear between one or two grades.Operation one
Two grades of shift fork B1 move forward one or two grades of clutch collar J1, so that the internal spline and first speed driven gear of one or two grades of clutch collar J1
The external splines of G21 combines, and power is transferred to first speed driven gear G21 by one grade of driving gear G11, by first speed driven gear
The external splines of G21 is transferred to one or two grades of clutch collar J1, then is transferred to one or two grades of splined hub G22, so that it is transferred to jackshaft S2, in
Between axis S2 with one grade rotate.Operating one or two grades of shift fork B1 moves backward one or two grades of clutch collar J1, so that one or two grades of clutch collar J1
Internal spline in conjunction with the external splines of two grades of driven gear G23, power is transferred to two grades of driven gears by two grades of driving gear G12
G23 is transferred to one or two grades of clutch collar J1 by the external splines of two grades of driven gear G23, then is transferred to one or two grades of splined hub G22,
To be transferred to jackshaft S2, jackshaft S2 is rotated with two grades.
Three fourth gear gears-shifting theories: three fourth gear clutch collar J2 are in an intermediate position, realize the neutral gear between three fourth gear.Operation three
Fourth gear shift fork B2 moves forward three fourth gear clutch collar J2, so that the internal spline of three fourth gear clutch collar J2 and third gear driven gear
The external splines of B39 combines, and power is transferred to third gear driven gear G24 by third speed drive gear G13, by third gear driven gear
The external splines of G24 is transferred to three fourth gear clutch collar J2, then is transferred to three fourth gear splined hub G25, so that it is transferred to jackshaft S2, in
Between axis S2 rotated with third gear.Operating three fourth gear shift fork B2 moves backward three fourth gear clutch collar J2, so that three fourth gear clutch collar J2
Internal spline in conjunction with the external splines of fourth gear driven gear G26, power is transferred to fourth gear driven gear by fourth gear driving gear G14
G26 is transferred to three fourth gear clutch collar J2 by the external splines of fourth gear driven gear G26, then is transferred to three fourth gear splined hub G25,
To be transferred to jackshaft S2, jackshaft S2 is rotated with fourth gear.
Reverse shift principle, as shown in fig. 7, reverse idler gear G0 is often engaged with height reverse gear clutch collar J3, in reverse gear
When neutral position, reverse idler gear G0 (as shown in G0 (1) position of Fig. 7) cannot be engaged with reverse driving gear G16, output
Neutral gear.When reverse speed fork B4 drives reverse idler gear G0 forward slip, reverse idler gear G0 while and reverse driving gear
G16 and height reverse gear clutch collar J3 engagement, exports reverse gear, at this time shown in the G0 (2) of the position of reverse idler gear G0 such as Fig. 7.
High and low shift gears-shifting theory.High and low shift clutch collar J3 is in an intermediate position, realizes the neutral gear between high and low shift.Operation is high
Low-grade shift fork B3 moves forward high and low shift clutch collar J3, and the internal spline of high and low shift clutch collar J3 and high speed gear G27's is outer
Spline combines, since high speed gear G27 passes through spline package on jackshaft S2, the interior flower of high and low shift clutch collar J3
Essence of the key in conjunction with the external splines of high speed gear G27 is so that height reverse gear splined hub G28 is in conjunction with jackshaft S2.At this time
High and low shift clutch collar J3 is exported with top gear.Operation high and low shift shift fork B3 moves backward high and low shift clutch collar J3, and high and low shift connects
The internal spline of trap J3 is in conjunction with the external splines of bootom gear G29, due to high speed gear G27 and triple gear driving gear
G17 is often engaged, and triple gear driving gear G17 is integrated with triple gear driven gear G15, triple gear driven gear G15
