Description
Technical field
The present invention relates to a kind of shoveling, loading, excavation, wheeled multipurpose engineering trucks such as traction are used transmission device, and particularly ten tons of left and right sides engineering trucks are used the counter shaft mechanical transmission.
Background technique
Countershaft transmission generally is made up of fluid torque converter and a multi-axle gear-box, because simple in structure, processing and assembly precision guarantee easily; On engineering truck, use morely, but the shortcoming of countershaft transmission is that size, weight are bigger, all uses the rotary clutch gear shift; So the life-span uses fixed clutch low, general gear is many more, and clutch is arranged manyly more; The space is just big more, and in traditional speed changer, drives for realizing 4 wheel driven; Must install transfer case additional could realize, because the transfer case housing volume is bigger, also big to the arrangement space requirement of car load.
Summary of the invention
For solving the defective that the existing technology countershaft transmission exists, the present invention provides an installing space little, the countershaft transmission that gear is more.
The present invention is achieved in that transmission for hydraulic variable speed device comprises that mainly torque-converters part, direction control section, basic trnasmission part and front and back drive output control part and grade.
Torque-converters partly comprises lock-up clutch, turbine, pump impeller, guide wheel; Be single-stage two phase element type fluid torque converters; Wherein pump impeller is connected with motor; Power by turbine output shaft (7) output, also can combine through the electromagnetic valve lock-up clutch behind the guide wheel bending moment simultaneously, turbine directly is connected with motor realizes locking output.
The direction control section comprises forward gear clutch (5) and retreats a grade clutch (6); Need only the combination of controlling forward gear clutch (5) or retreating a grade clutch (6); Just can control the running forward or backwards of transmission for hydraulic variable speed device output, reach the purpose that the control vehicle moves forward and backward.
Basic trnasmission partly comprises one grade of clutch (1), second gear clutch (2), third gear clutch (3), fourth gear clutch (4), idler mechanism (9), low gear (10), high speed driving gear (11) and high low speed transducer (13).Through the combination of different gear clutches and the conversion of high low speed switching mechanism, can realize the output of speed changer at different gears.
Direction control section and basic trnasmission clutch portions all adopt the rotary clutch structure; Forward gear clutch (5) and retreat a grade clutch (6) and turbine output shaft (7) and be triangularly arranged; Third gear clutch (3) through first with retreat a grade clutch (6) and link to each other; Second gear clutch (2) links to each other with forward gear clutch (5) through second; One grade of clutch (1) links to each other with second gear clutch (2) with third gear clutch (3) simultaneously, and idler mechanism (9) all links to each other with high speed driving gear (11) with low gear (10) simultaneously, and first output shaft (12) all links to each other with high speed driving gear (11) with low gear (10) simultaneously.
Before and after drive output control part and comprise first output shaft (12) and separator (14), the combination of control separator (14) and first output shaft (12) or separate to realize respectively that forerunner and rear-guard export jointly or only carry out rear-guard and export.
With the direction control section, basic trnasmission part and front and back are driven output control part and all are integrated in the case of transmission (8), make the more compact structure of whole transmission device, and volume is littler.
Beneficial effect of the present invention has:
1, adopt the direction control section, the output control part integral structure is driven in basic trnasmission part and front and back, makes the volume of this transmission for hydraulic variable speed device little, compact structure.
2, can realize simultaneously that eight forward gearss, eight retreat shelves and a geared neutral.
3, can realize forward and backward drive output simultaneously or rear-guard output separately.
Description of drawings
Fig. 1 is a countershaft transmission transmission diagram of the present invention.
Fig. 2 is the corresponding gear table of transmission diagram of Fig. 1, and "+" expression clutch is in running order in the table
Embodiment
As shown in Figure 1 pump impeller in the torque-converters is connected with motor; Make turbine output shaft (7) conduct power to forward gear clutch (5) or retreat a grade clutch (6) through leg-of-mutton arrangement mode; When forward gear clutch (5) engages the just commentaries on classics that realizes output, when retreating the counter-rotating that realizes output when a grade clutch (6) engages.
One grade of clutch (1) of basic trnasmission part, second gear clutch (2), third gear clutch (3), fourth gear clutch (4) are realized advancing one grade, second gear respectively with forward gear clutch (5) or retreat the logical oil of a grade clutch (6) and engage; Third gear, fourth gear or slow astern shelves, second gear; Third gear, fourth gear, idler mechanism (9) and low gear (10) and high speed driving gear (11); High low speed transducer (13) is realized respectively advancing at utmost speed and is retreated totally eight shelves and low-speed forward is retreated the switching of totally eight shelves, when high speed driving gear (11) is worked, realizes eight shelves at a high speed; When low gear (10) is worked, realize eight shelves of low speed.
Through control separator (14) and the combination of first output shaft (12) with separate, realize the forerunner, rear-guard is exported simultaneously or separately from rear-guard output, thereby control the four-wheel drive or the two-wheel drive of vehicle.
With forward gear clutch (5); Retreat a grade clutch (6); One grade of clutch (1), second gear clutch (2), third gear clutch (3), fourth gear clutch (4), idler mechanism (9), high low speed transducer (13); Separator (14) and first output shaft (12) all are integrated in the case of transmission (8), have reduced physical dimension.
The joint situation of gear is seen Fig. 2, in practical application, owing to require reverse speed low, generally with the software lock of higher reverse gear, to reach the purpose of protection people and transmission device through controller.
