Summary of the invention
The purpose of this utility model:
For solving the deficiency that existing load-carrying dumping car, city bus and special vehicle main transmission exist, the invention provides a kind of fluid torque converter with retarder.
The present invention is achieved in that
A kind of fluid torque converter with retarder mainly is made of parts such as lock-up clutch (1), flywheel (16), oil pump (14), main control valve (17), torque converter assemblage and speed reducer assemblies, lock-up clutch (1), torque converter assemblage and speed reducer assembly are integral structure, have adopted the structural type of built-in oil pump simultaneously.
Torque converter assemblage is made up of torque-converters housing (15), pump impeller (4), turbine (2), guide wheel (3), turbine output shaft (11) and lining (12) etc., and torque-converters housing (15), pump impeller (4), turbine (2) and guide wheel (3) are aluminium alloy castings.Pump impeller (4), flywheel (16) and driving gear (13) are rigidly connected by bolt, turbine (2) and turbine output shaft (11) are rigidly connected by spline, guide wheel (3) is connected by spline with lining (12), be rigidly connected by bolt with torque-converters housing (15) then, guide wheel (3) has overrunning clutch, and fluid torque converter is worked under bending moment and two kinds of operating modes of coupling.
The power of input passes to pump impeller (4) through flywheel (16), driving hydraulic transmission oil does work in the circulate circle of torque-converters, drive turbine (2) rotation, produce the bending moment effect when hydraulic transmission oil is flowed through guide wheel (3) simultaneously, last power is exported by turbine output shaft (9).
When needing direct transmission, can pass through the combination of main control valve (17) control lock-up clutch (1), turbine (2) is directly exported with the motor realization power that is rigidly connected.
Speed reducer assembly is positioned at the turbine output shaft rear end, is made up of reducer shell (8), stator (5), rotor (6) and control valve (7), and reducer shell (8) is an aluminium alloy castings.Reducer shell (8), stator (5) are rigidly connected by bolt with torque-converters housing (15).Rotor (6) is rigidly connected by spline with turbine output shaft (11), rotates together.Oil mass size by control valve (7) control enters retarder can obtain different braking moments.
Oil pump (14) is located at torque-converters housing (15) inside, is driven by the driving gear (13) that is meshed with pump impeller (4).
Main control valve (17) is positioned at the below of torque-converters housing (15), the pressure and the flow direction of control hydraulic transmission oil.
Between torque-converters housing (15) and driving gear (13), seal arrangement (9) is set, between reducer shell (8) and the turbine output shaft (11) seal arrangement (10) is set, make fluid torque converter forward and backward sealed at both ends, realized the dry type transmission.
Beneficial effect of the present invention has:
1, lock-up clutch, retarder and torque-converters are integral structure, have adopted built-in oil pump simultaneously, and this makes the compact structure of torque converter drive device.
2, bigger housing adopts the aluminium alloy castings structure, has alleviated the weight of fluid torque converter greatly.
3, the forward and backward two ends of torque-converters all are the dry type transmissions, have reduced the situation of leakage of oil, make things convenient for the use of dry clutch simultaneously.
Description of drawings
Fig. 1 is the transmission sketch of a kind of fluid torque converter with retarder of the present invention.
Fig. 2 is the structure diagram of a kind of fluid torque converter with retarder of the present invention.
Fig. 3 is the front view of a kind of fluid torque converter with retarder of the present invention.
Embodiment
1, power transmission line
As shown in Figure 2: the pump impeller in the torque-converters (4) is connected with motor through flywheel (16), the driving gear (13) that links to each other with pump impeller (4) drives oil pump (14), pump impeller (4) rotating band hydrodynamic power transmission oil acting simultaneously, drive turbine (2) rotation, give turbine output shaft (11), outputting power with transmission of power.
Hydraulic transmission oil is flowed through when being with the guide wheel (3) of overrunning clutch, by changing flow direction, output torque is increased, and plays the effect that becomes moment of torsion output.
When the direct outputting power of needs, main control valve (17) control enters the hydraulic transmission oil of lock-up clutch (1), and behind lock-up clutch (1) locking, turbine directly combines with the motor rigidity, and transferring power realizes direct driving force output.
2, hydraulic transmission oil transfer route
Hydraulic transmission oil enters main control valve (17) through the effect of oil pump (14), carries out entering in the torque-converters after voltage stabilizing is regulated, and hydraulic transmission oil is flowed through when being with the guide wheel (3) of overrunning clutch, increases output torque by changing flow direction.High temperature hydraulic transmission oil in the torque-converters is got back to fuel tank after heat exchanger of engine is cooled.
When the direct outputting power of needs, main control valve (17) control enters the part hydraulic transmission oil of lock-up clutch (1), and lock-up clutch (1) locking rear engine and flywheel are rigidly connected, and realizes the output of high efficiency power.
When needs slow down fast, make the hydraulic transmission oil of returning enter the retarder inner chamber by control valve (7) from heat exchanger of engine, rotor (6) is produced a braking moment, and pass to turbine output shaft (11), realize the function that fluid torque converter slows down fast.
