Amount is also in increase.It is high to the skill requirement of operating personnel and in existing speed changer, the gearshift of two-pack axle not tape synchronizer is difficult,
Net synchronization capability is poor;The reliability of this quick condition application common synchronization device of two-pack axle is relatively low, easy earlier period damage.In addition,
The scope gear odd-side of existing same moment of torsion section speed changer is two-pack axle construction, is slowed down smaller, and speed changer climbs gear speed than small, and vehicle is moved
Power performance can not meet the requirement of complex road condition.
The content of the invention
There is provided a kind of heavy vapour for the problem of present invention is in order to solve existing speed changer net synchronization capability and poor power performance
Automobile-used nine gears synchronizer speed variator.
The present invention is realized using following technical scheme:A kind of heavy-duty car nine gear synchronizer speed variators, including one
Main tank is provided with individual housing, housing and the scope positioned at rear side keeps off odd-side, main tank is two-pack axle construction, is provided with it defeated
Enter axle, countershaft, main shaft, travelling gear and the idle pulley that reverses gear, one two three four gear travelling gears are provided with high reliability bipyramid base steel
Sprayed molybdenum lock ring type synchronized, idle pulley both sides of reversing gear are there is provided end face bearing, and scope gear odd-side is planetary mechanism, are provided with too in it
Positive wheel, planetary gear, output shaft and single cone base steel sprayed molybdenum lock ring type synchronized, main tank front portion is provided with forced feed lubrication oil pump, scope
Gear odd-side rear portion is provided with rearmounted power takeoff.
During operation, power is delivered to transmission input shaft from engine, and power is delivered into two pairs simultaneously by input shaft
On axle, then spindle transmission gear is delivered to, then the synchronizer of any gear of main tank is combined, power passes through the synchronizer after combination
It is delivered on main shaft, scope gear odd-side planetary mechanism is transferred power to by main shaft, the switching of auxiliary box synchronizer is kept off by scope,
Output shaft is transferred power to, realizes that speed changer becomes the effect turned round.The setting of high reliability synchronizer ensure that speed changer
The simplicity of interior gear shift operation is reliable;Big gear speed of climbing climbs gear high pulling torque output, powerful than realizing speed changer.Overcome existing
The problem of speed changer net synchronization capability and poor power performance.
Main tank is two-pack axle construction, and the one two three four gear travelling gears on main shaft set the spray of high reliability bipyramid base steel
Molybdenum lock ring type synchronized, it is ensured that synchronizer remains able to reliable synchronization under quick condition, and service life is long.
Travelling gear in main tank is designed using large speed ratio, scope gear odd-side be big retarding than planetary mechanism so that real
Existing speed changer climbs gear speed than being more than 13, and vehicle is realized in starting climbs gear high pulling torque output, powerful.
Speed changer front portion is provided with forced feed lubrication oil pump, by lubricating oil injection with vittate input shaft, main shaft, output
Axle, lubricates each position part, extends speed changer service life.
Scope gear odd-side rear portion is provided with the rearmounted power takeoff from the idle pulley power taking of reversing gear in main tank, reduces speed changer wide
Degree and height.
Reverse gear and end face bearing is added between idle pulley and housing, bear axial force.
Reasonable in design of the present invention is reliable, enhances the handling and dynamic property of speed changer, improves its service life,
Reliability is high, while the performance requirement under various complex road conditions to speed changer is met, with rational in infrastructure, function admirable and operation
Convenient advantage.
