Definitions

  • the invention relates to the gearbox of vehicles with automatic transmission.
  • the invention particularly relates to a gearbox locking system with a simple structure, which enables the motion of the rod connected to the push-pull wire via the clutch element connected with the gearstick, and ensures it to be active only in the park position and otherwise releases the wire.
  • the push-pull wire is present to enable the locking when the gearstick is in park position.
  • this wire When the gear is in park position, this wire is in pushed state by the shifting mechanism and in locked state. It is required to be released in other gear positions.
  • there is a mechanical system which clutches or unclutches the wire which is called 'clutch-unclutch'.
  • Such systems result in complicated designs in addition to increasing the costs.
  • the wire is never released in such systems.
  • the wire is required to be engaged in positions other than the park position. When the gear is shifted towards D+ and D- positions, it slides from 'clutch-unclutch' however the wire is never fully released.
  • This invention relates to a gearbox locking system which meets the aforementioned requirements, overcomes all disadvantages and provides some additional advantages.
  • the main purpose of the gearbox locking system of the invention is enabling the gearbox locking action in the relevant park position, by connecting the rigid rod, which has a curved surface at the end, to the push-pull wire and enabling the contact between the mentioned curved surface and the clutch element, which is connected to the gearstick.
  • Rod is unclutched later in other positions by removing it from the locking point with the help of the pulling surface which is shaped on the gearstick.
  • the problem of the push-pull wire always staying connected with gearstick is thus solved.
  • the 'clutch-unclutch' which clutches or unclutches the wire, eliminates the need for a mechanical system, a low level complexity and low cost system is achieved.
  • Another purpose of the invention is to provide a motion with a certain level of order by bearing the rod's motion by the channels formed on the housing parts in which the rod moves. This way, possible faults are prevented by providing thus working order.
  • Another purpose of the invention is moving the rod farther from the clutching point by the help of the pushing surface which is formed on the structure connected to the gearstick and positioned at the farther side with respect to the axis of rotation.
  • a shifter clutching system which enables mechanically locking of the gearbox by applying tension to the push-pull wire via the motion on the housing of the transmission connection element connected to the gearstick, and releases in other positions.
  • the developed gearbox locking system comprises; at least one rod which is connected to the push-pull wire and a curved element formed on its one end, at least one clutch channel, which is formed on the housing provide to move the transmission connection element towards the turning point when it is moving in the forward direction and move that away when it is moving backward direction by guiding to the curved element, at least one clutch element formed on the transmission connection element and performs pushing of the curved element to forward direction, at least one pulling surface formed on the transmission connection element and performs pushing of the curved element to backward direction, a clutch space which is formed on the transmission connection element, between the clutch element and the pulling surface, and limits the motion of the curved element when the transmission connection element is motionless.

  • the vertical guide channel (22) formed on the housing (20) guides the curved element (41 ) to travel freely in forward (x) and backward (y) directions.
  • the structure of the transmission connection element (30) plays an important role in directing and controlling the curved element (41 ).

Therefore when the transmission connection element (30) moves in the backward (y) direction, the rod (40) is pushed away from the turning point (O) and delivering the curved element (41 ) from the clutch channel (21 ) to the vertical guide channel (22) is provided.
