Specific embodiment
The present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.
A kind of horizontal engine of motorcycle reverse gear position limiting structure, including the limiting slot 2 being located on speed transmission drum 1 and limiting slot 2
The pressing plate 4 of the limit shaft 3 of cooperation, support limit axis 3,
The both ends of speed transmission drum 1 can rotate respectively in left box body 5,6 axial limiting of right case.In right case 6
End (in figure be right part) processing one limiting slot 2, the limiting slot 2 are in open type in the circumferential direction, one end is opening
201, the other end be close mouth 202 and by the trend and speed transmission drum 1 of closing mouth 202 to opening 201 into shelves when it is (supreme by low grade
Shelves) steering it is consistent；
An end face 7 for fixation clip 4 is added on the right case 6 of traditional structure, the end face 7 and speed transmission drum 1 it
Between right case on process 8, two fixation holes 9 of a through-hole, the central axis of the through-hole 8 passes through the axis of speed transmission drum 1, two
A fixation hole 9 is located at the two sides of through-hole 8；
Oil sealing 14 is housed on pressing plate 4, and is screwed into two fixation holes 9 and is packed on aforementioned end face 7 by two bolts 10；
The end of limit shaft 3 is inserted into limiting slot 2 after sequentially passing through oil sealing 14, pressing plate 4, through-hole 8, and the other end, which is equipped with, is located at right case
The handle 11 of 6 outside of body；One boss 301 is set on the limit shaft 3 in right case 6, is pressed from both sides between the boss 301 and pressing plate 4
Equipped with the compressed spring 12 around limit shaft 3, it is always positioned at limit shaft 3 in limiting slot 2 by the bounce of compressed spring 12,
And when motorcycle speed transmission drum 1 is in neutral gear, the side of limit shaft 3 abuts the closing mouth 202 of limiting slot 2, does not take out in limit shaft
Speed transmission drum 1 is limited from the case where to rotate to the direction of reverse gear.
As further improvement of the invention, the groove width of limiting slot 2 is 5mm ± 3mm, groove depth is 3mm ± 2mm, center
The distance between positioning end face 101 of line and 1 left part of speed transmission drum is 70mm ± 5mm.
As further improvement of the invention, the bottom surface of limiting slot 2 is plane, easy to process；Closing mouth 202 is cylinder,
But the present invention does not limit this.
As further improvement of the invention, the distance between end face 7 and 1 axis of speed transmission drum are 55mm ± 10mm；Through-hole 8
Diameter be 8mm ± 6mm, the distance between center line and cabinet faying face 13 be 24mm ± 2mm.
As further improvement of the invention, the handle 11 is U-shaped, and the other end of one side and limit shaft 3 connects
Connect, another side is as force side, detached out of limiting slot 2 by the force side by axis 3 is limited.
As further improvement of the invention, it is equipped with a circular protrusion 401 in the middle part of pressing plate 4, which is inserted into
In through-hole 8 and the sandwiched compressed spring 12 between boss 301.
A kind of working principle of horizontal engine of motorcycle reverse gear position limiting structure of the present invention is as follows:
In motorcycle ride, if rider causes to hang reverse gear due to maloperation, speed transmission drum 1 is needed from neutral gear
It is rotated to the direction of reverse gear.When speed transmission drum 1 is in neutral gear, the side of limit shaft 3 abuts limiting slot and closes mouth 202, makes speed transmission drum
1 cannot rotate to the direction of reverse gear, directly can not switch to reverse gear from neutral gear, eliminate the security risk as caused by maloperation.
If necessary to from neutral gear switch to reverse gear, motorcycle need to only be suspended to safety zone, by handle 11 manually by limit shaft 3 from
It is detached in limiting slot 2, speed transmission drum 1 can be switched to reverse gear from neutral gear.
As forFree shift process in, limit shaft 3 is with respect to speed change
Drum 1 is moved along limiting slot 2, and speed transmission drum 1 is not interfered to rotate in the circumferential direction, even if limit shaft 3 is from the opening of limiting slot 2
The outer surface for abutting speed transmission drum 1 is skidded off at 201, and speed transmission drum 1 will not be interfered to rotate in the circumferential direction, thus the present invention proposes
Reverse gear position limiting structure do not influence aforementioned free shift process.
The technical principle of the invention is described above in combination with a specific embodiment.Those skilled in the art are on basis of the invention
On do various modifications or additions or be substituted in a similar manner, without departing from structure of the invention or surmount this
Range as defined in the claims should belong to protection category of the invention.
