Abstract
The present invention relates to a hydraulic actuating device for electronically controlled automatic gear shifting systems of automobiles, which is an actuator module for controlling a transversely arranged gearboxes. The device uses the technology of electric-hydraulic control and takes an integrated oil path plate as a foundation. A gear shifting oil cylinder body parallel to an upper plate of the integrated oil path plate is vertically plugged into the integrated oil path plate. The device gives full play to the advantages of reliability, wear resistance and stability of a hydraulic mechanism and breaks through the technical barrier of large torsion, high current, instability and unreliability when a motor is driven to work, and thus, the present invention achieves the demand for using large quantities of automobiles.
Description
Technical field
The present invention is a kind of hydraulic pressure execution device of automatic speed-changing system of Vehicle Electronic Control, is the actuator module of handling horizontal gearbox.
Background technique
Present similar actuator, as describing among the Chinese patent specification CN2378236Y (on May 17th, 2000 is open), its gear-selecting and shifting executing mechanism adopts motor drive mode mostly, though motor driving control is simple, but because gear shift action change in torque is big, unexpected, make the load shock of motor serious, the wire harness current overload, reliability, Security are had a strong impact on, and can not adapt to the highly reliable requirement of automobile.
Summary of the invention
In order to overcome the existing deficiency that electric drive actuator moment of torsion is little, electric current is excessive, the present invention adopts electrohydraulic control technology, and based on the integrated oil path plate, the gear selecting oil cylinder body vertically inserts the integrated oil path plate, and the gear shifting oil cylinder body is parallel to the integrated oil path upper plate.The oil inlet and outlet of gear selecting oil cylinder body and gear shifting oil cylinder body is anchored on the integrated oil path plate by hollow screw.Load onto the gear selecting shift fork in the middle of the gear selecting oil cylinder body, the prong of gear selecting shift fork front end is stuck on the change lever guiding groove that selects on the shift shaft, and by the fastening gear shift piston core of nut and the axis of guide, the gear shift piston rod inserts the gear shift shifting block freely respectively at the connecting rod two ends.The gear shift shifting block is contained on the axis of guide by axis of guide nut, the oil cylinder that gear shift piston core and gear shift piston sleeve are formed is arranged in parallel with the oil cylinder that the gear shift piston rod is formed, the centre axis of guide that is arranged in parallel, composition gear shifting oil cylinder body, be stuck in change lever bulb end, the realization engage a gear is plucked the shelves action.The present invention and horizontal mechanical gear box select the gear shift axle bed, link together by former design screw position and integrated oil path plate, form organic overall structure.All put positioning adapter on the piston rod of gear selecting and gear shifting oil cylinder body, so that the position location of control gear shift shifting block and gear selecting shift fork.The invention has the beneficial effects as follows, whole hydraulic actuation device comprises the closed module that is integrated into of integrated oil path plate compactness, given full play to hydraulic mechanism reliably, easy to wear, unstable advantage, high pulling torque, big electric current and unstable reliable technique difficulty when making the automobile mechanical gear shifting box automatic speed-changing system break through the work of employing motor driving have reached the automobile requirement of using in enormous quantities.
