Abstract
The utility model relates to a gear reversing element for mechanical type gear box, in particular to a gear reverse steering device of mechanical type gear box. The utility model is characterized in that: the utility model is composed of a support plate(1) which is articulated with a shifting fork(4) through a rivet(2). A shifting pin(3) is inserted movably in carved groove(7) of the shifting fork. Rotation of the shifting fork(4) drives the shifting pin(3) to move up and down in the carved groove(7). A return spring(5) is hung into slot of the shifting fork(4) so as to achieve return of the shifting fork(4). When in neutral position, position of the shifting pin(3) in the carved groove is spontaneously locked in order to prevent faulty gear reverse. The shifting pin(3) can slide along the carved groove. Under external force, the shifting pin (3) will move upward along the carved groove and bring the shifting fork(4) moving upward. The shifting fork(4) brings reversing gear(6) moving upward so as to finish action of gear conversion. Under external force, the shifting pin(3) moves downward along the carved groove, and the shifting fork(4) moves downward as well when driven by the return spring(5) and the reversing gear(6) to finish removing the gear. The utility model has such advantages as simply structure, low cost, agile operation and use.
Description
Technical field: the utility model relates to the reverse gear mechanism of mechanical type speed-changing gear box, is specially the reverse gear Effector of mechanical type speed-changing gear box.
Background technique: at present common automobile is many by a control fork control reverse speed fork with the reverse gear control mechanism of mechanical gearbox, and self-locking mechanism also designs in control and sticks; Perhaps with the shared cover lazy-tongs of forward gears, reverse gear adopts the mode of often nibbling to handle reverse gear.The mode that its self-locking mechanism generally adopts steel ball and spring to pin the reverse gear shift shaft realizes.
Summary of the invention: the purpose of this utility model just provide a kind of simple in structure, with low cost, manipulate the reverse gear Effector of mechanical type speed-changing gear box flexibly.The purpose of this utility model is achieved in that it is made up of dunnage (1), rivet (2), gear shift pin (3), shift fork (4), return spring (5), reverse gear (6), curvilinear groove (7).Dunnage (1) is articulated and connected by rivet (2) with shift fork (4); Gear shift pin (3) is inserted in the shift fork curvilinear groove (7) and connects movingly, and the rotation of shift fork (4) is to drive through gear shift pin (3) moving up and down in curvilinear groove (7) to connect; Return spring (5) hangs in the groove of shift fork (4), realization shift fork (4) return.When neutral position, the position self-locking of gear shift pin (3) in curvilinear groove prevents reverse gear mistake extension.Gear shift pin (3) slides along curvilinear groove in curvilinear groove.Gear shift pin (3) moves upward along curvilinear groove under the effect of external force, then drives shift fork (4) and moves upward, and shift fork (4) drive reverse gear (6) moves upward to finish and hangs the reverse gear action.Gear shift pin (3) moves downward along curvilinear groove under the effect of external force, moves downward at the drive lower shift fork (4) of return spring (5) and gear shift pin (3), and shift fork (4) drives reverse gear (6) and moves downward to finish and plucks the reverse gear action.When neutral position, suppose that shift fork (4) moves upward under the drive of reverse gear, and the position of gear shift pin (3) this moment in curvilinear groove has self-locking action, and shift fork (4) just is stuck in gear shift pin (3) and can not moves upward in the curvilinear groove, prevented reverse gear mistake extension.The utility model advantage is: simple in structure, with low cost, manipulate flexibly.
Description of drawings: Fig. 1 is the utility model structural principle schematic representation.
Embodiment: dunnage (1) is articulated and connected by rivet (2) with shift fork (4); Gear shift pin (3) is inserted in the shift fork curvilinear groove (7) and connects movingly, and the rotation of shift fork (4) is to drive through gear shift pin (3) moving up and down in curvilinear groove (7) to connect; Return spring (5) hangs in the groove of shift fork (4), realization shift fork (4) return.When neutral position, the position self-locking of gear shift pin (3) in curvilinear groove prevents reverse gear mistake extension.Gear shift pin (3) slides along curvilinear groove in curvilinear groove.The utility model working procedure: the gear shift pin moves upward along curvilinear groove under the effect of external force, then drives shift fork and moves upward, and shift fork drive reverse gear moves upward to finish and hangs the reverse gear action.The gear shift pin moves downward along curvilinear groove under the effect of external force, moves downward at the drive lower shift fork of return spring and gear shift pin, and shift fork drives reverse gear and moves downward to finish and plucks the reverse gear action.When neutral position, suppose that shift fork moves upward under the drive of reverse gear, and the position of gear shift pin this moment in curvilinear groove has self-locking action, shift fork and gear shift pin just are stuck in and can not move upward in the curvilinear groove, have prevented reverse gear mistake extension.The reverse gear control mechanism of the utility model gearbox is by increasing curvilinear groove at reverse speed fork on mounting plate, so and increase the reliability that a gear shift pin has increased reverse gear.The gear shift pin is when " A " position, and the gear shift pin has self-locking action, and reverse gear can not move up, and can prevent from like this to hang reverse gear by mistake, has increased the reliability of reverse gear.Realize the manipulation and the self-locking action of reverse gear with a return spring.Because except original reverse gear self-locking, the gear shift pin has self-locking action in curvilinear groove.
