Star plate is equipped with, and detent mechanism is provided with gearbox body, after the completion of speed-change and gearshift, detent mechanism and star plate
Positioning stop is cooperatively formed, in case on-slip shelves or moving back shelves.Existing speed transmission drum plate positioning component is included and turned with gearbox body
The torsion spring of the dynamic location-plate, the keeper being arranged on location-plate and the turning end for being arranged on location-plate for coordinating, is existed by torsion spring
Turning end applies pretightning force makes keeper be pressed in star plate, and the another of end is relatively rotated due to being arranged on location-plate keeper more
One end, the active force of torsion spring is delivered on keeper and to produces a certain degree of loss, compression of the keeper to star plate
Power is easily affected, higher to ensure performance requirement of the compression effect just to torsion spring, and because location-plate relatively rotates end
Effect of the other end without external force, stability it cannot be guaranteed that, and the stress of location-plate is not uniform enough in gear shift, so as to cause gear shift
It is not smooth enough.
Accordingly, it would be desirable to existing speed transmission drum plate positioning component makes it to make by less active force to being improved
Motion of the keeper to speed transmission drum plate produces larger and more uniform reaction force, so that location-plate is received during speed transmission drum gear shift
Evenly, gear shift is more smooth for power, while relatively low to the performance requirement that pretightning force provides part.
Utility model content
In view of this, the utility model provides a kind of speed transmission drum plate positioning component, and it can be made by less active force
Motion of the keeper to speed transmission drum plate produces larger and more uniform reaction force, so that location-plate is received during speed transmission drum gear shift
Evenly, gear shift is more smooth for power, while relatively low to the performance requirement that pretightning force provides part.
Speed transmission drum plate positioning component of the present utility model, including location-plate and the keeper being arranged on location-plate, it is fixed
Position plate one end is set in rotation with and turning end is formed on gearbox body, and the other end forms force side and under pretightning force effect
Keeper is set to be pressed in speed transmission drum plate for positioning stop.
Further, pretightning force is applied along the radially inner compression of speed transmission drum plate by location-plate force side to keeper
Power.
Further, the force side of location-plate applies the pretightning force, extension spring one end and positioning by an extension spring
Plate force side connects, and the other end is connected to gearbox body.
Further, keeper is arranged at location-plate at medium position.
Further, extension spring is connected by being mounted on to be formed with gearbox body on the hook set on gearbox body.
Further, the force side of location-plate is formed with the coupler body for extension spring connection.
Further, keeper is the roller bearing being connected with location-plate.
The beneficial effects of the utility model：Speed transmission drum plate positioning component of the present utility model, by applying in location-plate
Power end applying pretightning force makes keeper be pressed in speed transmission drum plate carries out positioning stop, and it can make positioning by less active force
Part produces larger and more uniform reaction force to the motion of speed transmission drum plate, so that location-plate stress is more during speed transmission drum gear shift
Uniformly, gear shift is more smooth, while relatively low to the performance requirement that pretightning force provides part.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the utility model structural representation.
Specific embodiment
Fig. 1 is the utility model structural representation, as shown in the figure：The speed transmission drum plate positioning component of the present embodiment, including
Location-plate 1 and the keeper 2 being arranged on location-plate 1, one end of location-plate 1 are set in rotation with to be formed on gearbox body 6 and turn
Moved end 1a, the other end forms force side 1b and keeper 2 is pressed in speed transmission drum plate for fixed under pretightning force effect
Position stop；As shown in figure 1, the end of speed transmission drum is provided with star plate 3, keeper 2 formed with star plate 3 often contact and
Plate 3 is pressed in the presence of pretightning force, the force side 1b of location-plate 1, rather than turning end 1a is put on due to pretightning force, so
Allow for keeper 2 for fulcrum is formed similar lever construction, when star plate 3 is moved, keeper 2 can pretightning force work
Larger and more uniform reaction force is produced with the motion of lower relative star plate 3, so as to ensure to position stopping effect；Wherein,
Location-plate 1 is plate body structure, and its turning end 1a is arranged on gearbox body 6 and rotatable by rotating shaft or Positioning screw 8, speed change
Casing 6 refers to the casing of gearbox, or when speed changer integrated installation on the engine when be engine housing；.
In the present embodiment, pretightning force by the force side 1b of location-plate 1 to keeper 2 apply along the radial direction of speed transmission drum plate 3 to
Interior thrust；I.e. keeper 2 be to the thrust that speed transmission drum plate 3 is produced along speed transmission drum plate 3 radially-inwardly, formed stabilization
And reliable compression, do not result in dislocation or eccentric wear.
In the present embodiment, the force side 1b of location-plate 1 applies pretightning force by an extension spring 4, the one end of extension spring 4 with
The force side 1b of location-plate 1 is connected, and the other end is connected to gearbox body 6；It is easily achieved, and is easily installed.
