Shift fork, spring that described cylinder connector inner end is connected with piston and is connected successively with piston; Described shift fork upper end is connected with the involute internal tooth casing be sleeved on output shaft external splines;
Described jack shaft is installed between Oil Guide stifle, and be provided with jack shaft gearwheel, jack shaft small gear successively before and after on jack shaft, described jack shaft gearwheel is connected with input shaft small gear, and described jack shaft small gear is connected with output shaft gearwheel.
Further, described output shaft gearwheel and output shaft adopt needle bearing to support.
Placement of the present utility model: the flange flower keyboard of front end connects the transmission shaft of former car gearbox output, the flange flower keyboard of rear end connects the transmission shaft driving back axle, and cylinder connector is for switching the conversion of gearbox high speed and low speed output;
Involute internal tooth casing is by fork controls slide anteroposterior, and air cylinder driven shift fork moves backward, and Spring driving shift fork moves forward; Tooth cover under the action of the spring, move forward to limit position and original in-situ, involute internal tooth casing one end is in conjunction with output shaft external splines, and the other end is in conjunction with input shaft external splines, realize direct outputting power, the power after the deceleration of another road dallies under the support of needle bearing; When cylinder connector has control pneumatic transmission fashionable, piston overpowers spring moves backward, and involute internal tooth casing moves backward under the effect of piston and shift fork, and input shaft external splines is thrown off in front end, rear end, in conjunction with the short tooth spline on output shaft gearwheel, realizes the transmission of power after slowing down to output shaft.
Transmission of power principle of the present utility model: input shaft inputs former car gearbox dynamic, output shaft external splines place delivered to by input shaft spline of leading up to.Another route input shaft small gear is delivered on jack shaft gearwheel, is delivered on output shaft gearwheel by jack shaft small gear, and this road power passes through two groups of gear reductions, reduction speed ratio six.
The beneficial effects of the utility model have: install simple and reliable, and pneumatic operation direct high and Ultra-Low Speed shelves switch.Without the need to changing rear propeller shaft during repacking, save recondition expense; During work, temperature rise is low, and moment of torsion is large; Repacking workload is little, and does not affect any function of former car.
