Abstract
The utility model discloses a gear-shifting mechanism for an automatic gearbox of a motor vehicle. The gear-shifting mechanism consists of a supporting frame assembly, a driving motor assembly and a connecting rod assembly, which are arranged outside a speed reducer, wherein the driving motor assembly is fixed on the supporting frame through a screw; a shaft on a driving motor speed-reducing mechanism extends out of a central opening of the supporting frame; a driving motor output rod is fixedly connected with the shaft on the driving motor speed-reducing mechanism; and the tail of a gearbox driving rod is connected with a gearbox input shaft through a key. Without additional devices, the gear-shifting mechanism can be assembled on a motor vehicle gearbox without problems.
Description
Technical field
The utility model relates to a kind of Motor Vehicle automatic transmission gear shift mechanism, belongs to the automobile gearbox field, many grades of gearshifts of particularly a kind of automatic transmission case.
Background technique
In recent decades, China's automobile industry develop rapidly, motor, transfer case etc. all progressively begin the autonomous Design research and development to design and the very high mechanism of processing request.Gearbox is exactly a representative of this series products; Gearbox is the vitals that is related to vehicle safety performance and driving comfortability ability; Gearbox complete set technology perfect needs more than ten years even decades, and the domestic company that has mature technology at present seldom adopts external forming techniques or directly uses foreign corporation's product so nowadays most domestic automobile manufacturer more; The spatial arrangement of each company's different automobile types is different with the moment requirement, and this just relates to a problem that is used.The internal structure of gearbox can't change; How externally adding some, to drive the purpose that force-transmitting devices reach gearshift be the emphasis of domestic gearbox research always, so design that a kind of volume is little, gearbox shifting operating mechanism that light weight, stability are high is crucial to a car.
Be well known that; 200810001018.8 propose a kind of control gear that relates to motor vehicle gearbox, it comprises fixed permanent magnet, fixed permanent magnet is installed on the gear box casing; And cooperate with movable permanent magnet through magnetic pull or magnetic repulsion; The latter is installed on the driving component, and the driving component driver part rotates or translation relative to the axle of shifting gears, to limit stable speed selection or drive range.
The existing shortcoming of this kind design has following several kinds.Number of spare parts is big, and design of part is complicated, and the machining accuracy of requirement is high, and the cost of producing and installing is all very high; The restriction that the moment scope that can reach receives factors such as magnetic force is bigger; When many gears were controlled, the volume increase was bigger; This kind design can not be heat insulation, is not suitable for gear controller and is installed near the vehicle of high temp objects; This scheme can not waterproof and dustproof, a little less than the adaptive capacity to particular surroundings.
Summary of the invention
The purpose of the utility model provides a kind of Motor Vehicle automatic transmission gear shift mechanism, and it can be without additional device being installed on the motor vehicle gearbox without a doubt.
The technological scheme of the utility model is achieved in that a kind of Motor Vehicle automatic transmission gear shift mechanism; Form by supporting frame assembly, drive motor assembly and connecting rod assembly; All assemblies are installed in the retarder outside; It is characterized in that: described supporting frame assembly is made up of supporting frame, bolt, and supporting frame passes through bolt for four jiaos and is fixedly connected supporting frame middle part perforate with gearbox; Described drive motor assembly; Form by outer thermal shield, seal washer, interior thermal shield, drive motor reducing gear, drive motor, interior thermal shield exit seal packing ring; Outer thermal shield cooperates with interior thermal shield goes into inside with drive motor reducing gear, drive motor cover; Be lined with seal washer between outer thermal shield and the interior thermal shield; One jiao of opening of interior thermal shield, the axle on the drive motor reducing gear leans out from opening, and the drive motor reducing gear is fixedly connected with interior thermal shield through four set screws; Described connecting rod assembly; Form by drive motor take-off lever, connecting rod, gearbox driveshaft, yielding rubber pad; The drive motor take-off lever flexibly connects through bolt and connecting rod one end, and the connecting rod the other end and gearbox driveshaft flexibly connect, and the joint is by the yielding rubber pad; The drive motor assembly passes through screw on supporting frame; Axle on the drive motor reducing gear leans out from the supporting frame central opening; Axle on drive motor take-off lever and the drive motor reducing gear is fixedly connected, and gearbox driveshaft tail end is connected through key with the gearbox input shaft.
The good effect of the utility model is an all-sealed structure, and waterproof and dustproof, heat insulation can realize that many gears freely control, and need not existing gearbox is carried out structure of modification; Reduce R&D costs, be applicable to various gearboxes, do not receive vehicle and gearbox shape limitation; Electrical control, fourbar linkage is carried out, and cost simple in structure is low; Control precise and stable, before operator cabin compare to the connecting rod between the gearbox (or drag-line) mechanism and take up room for a short time, flexibility ratio is high.
