Description
Technical field
The utility model relates to automobile component, particularly the actuator of automatic transmission clutch.
Background technique
What prior mechanical automatic transmission clutch actuator generally adopted is hydraulic control and Electric Machine Control dual mode, wherein hydraulic control mainly is to adopt motor-brace and connecting rod framework, by moving of motor driving connecting rod, drive the to-and-fro motion of hydraulic cylinder piston, thereby realize the separation and the combination of clutch; And Electric Machine Control mainly is to adopt motor-screw-nut structure, and by the rotating band movable wire thick stick rotation of motor, the rotation of leading screw drive nut again moves reciprocatingly, thereby realizes the separation and the combination of clutch.Though this dual mode can both make clutch separation and combination, the drive mechanism that this dual mode adopted is more complicated all, and the component of its drive mechanism are more, difficulty of processing is big, simultaneously, because the drive mechanism more complicated causes the stationarity of transmission relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of mechanical drag-line automatic transmission clutch actuator, to simplify its drive mechanism, improves the stationarity of transmission simultaneously.
Mechanical drag-line automatic transmission clutch described in the utility model actuator, comprise housing, be installed in driving mechanism and angle transducer on the housing, driving mechanism comprises motor, turbine, scroll bar, transition gear, tooth bar and drag-line, scroll bar one end is connected with motor shaft, turbine and transition gear are installed on the housing by rotating shaft, turbine is meshed with scroll bar, and turbine one end is provided with internal tooth, and by this internal tooth and transition gear engagement; Tooth bar is installed on the housing by linear bearing, mesh with transition gear, be fixed with position limit pin on the tooth bar, be fixed with fixing pin on the housing, between position limit pin and fixing pin, be connected with extension spring, extension spring vertically is installed in the housing along tooth bar, and when tooth bar extend out to ultimate range in housing, described position limit pin contacted with housing; Drag-line is positioned at outside the housing, and the one end is connected with tooth bar one end.
The other end of tooth bar is connected with clutch release fork, starting electrical machinery, motor shaft drives scroll bar and rotates, worm screw drives turbine rotation, turbine drives the transition gear rotation with its internal tooth engagement, and the tooth bar that transition gear drives with its engagement again moves, and tooth bar just drives connected drag-line and advances or retreat, and then the clutch fork that matches with release bearing of drive, the combination that realizes clutch and transmission input shaft with separate.
Extension spring can give the pretightening force of tooth bar and transition gear engagement, make moving of tooth bar more steady, and position limit pin can limit the ultimate range that tooth bar stretches out outside housing.
Tooth bar offers step hole at the end face with the drag-line connecting end, drag-line is being provided with half sphere shape with the tooth bar connecting end, described step hole port is equipped with circlip for hole, between circlip for hole and step hole end face, be provided with stop collar, the stop collar internal surface has spherical in its port, and the half sphere shape of described drag-line is arranged in step hole and can fits with the spherical of stop collar port.
This of drag-line and tooth bar kind of linkage structure can make drag-line with respect to tooth bar around the drag-line rotational, simultaneously drag-line can also be done the swing of certain amplitude with respect to the tooth bar port, realizes that rotary type is connected thereby make between drag-line and the tooth bar.
The other end at drag-line is connected with the hemisphere nut, this hemisphere nut matches with the hemispherical-shaped aperture of clutch shifter, can make drag-line with respect to clutch shifter around the drag-line rotational, simultaneously drag-line can also be done the swing of certain amplitude with respect to clutch shifter, realizes that rotary type is connected thereby make between drag-line and the clutch shifter.
The sensor axis of angle transducer on housing, is equipped with tooth sector by Bearing Installation on the sensor axis, tooth sector is connected with the sensor axle key, and meshes with described transition gear.
The combination that the kind of drive of the utility model by turbine worm, gear rack realizes clutch and transmission input shaft with separate, and be equipped with the pretension effect of extension spring, so power transmission is very steady, and simple in structure, reliable; Drag-line adopts rotary type to be connected with tooth bar and clutch shifter, and greatly degree has reduced the fracture rate of drag-line; Tooth sector on the sensor axis of angle transducer and transition gear engagement, operating rate and the displacement that can accurately gather tooth bar are so can realize accurately control to clutch shifter.
