Abstract
The invention discloses a kind of protection structure of motorcycle engine gear-shift shaft; including the gear-shift shaft being arranged on below engine; also include gear-shift shaft guide holder; the gear-shift shaft guide holder is provided with the mounting hole for being passed through for gear-shift shaft; at least two bearings are provided with the mounting hole; the bearing inner sleeve is equipped with guide pin bushing, and the gear-shift shaft is located in the guide pin bushing；The gear-shift shaft guide holder is each side connected with buffer spring part, and the other end of the buffer spring part is fixed in engine housing.The present invention is that gear-shift shaft improves good support by least two bearings, avoids gear-shift shaft from deforming in the axial direction, bearing also allows the rotation of gear-shift shaft more smoothly, flexible；Gear-shift shaft guide holder is each side connected with buffer spring part, when axial deformation occurs in gear-shift shaft stress, is corrected by buffer spring part, further reduces the axial deformation of gear-shift shaft, improves service life.
Description
Technical field
The present invention relates to Motorcycle Engine Technology field, specifically a kind of protection knot of motorcycle engine gear-shift shaft
Structure.
Background technology
In traditional motorcycle gear-shifting structure, clutch separation structure and engine gear-shift shaft are two separate machines
Structure, clutch separation structure mainly include control crank, clutch cable and the coupled controlled clutch that is used for and separated
Clutch operating lever.Clutch operating lever is arranged on engine body, and engine gear-shift shaft then passes through engine body,
Input exposes to the left crankcase left side.When carrying out shift using traditional motorcycle gear-shifting structure, user grips and grasped first
Make control crank, control crank control drag-line, acted by cable control clutch operating lever, so that the machine such as clutch push rod
Structure separates to clutch, and then in the state of control crank is gripped, pin steps on the Shift lever being connected with engine gear-shift shaft,
Control the gear-shift shaft to be acted by Shift lever, gear-shift shaft driving gear is carried out speed Control, when shift is completed
Release handle again afterwards.Existing horizontal four-stroke engine at present, because profile size limits, gear-shift shaft can extend lengthening,
Gear-shift shaft bending can be caused in actual use, while casing oil sealing easily wears, and causes engine oil leakage to cause to damage
It is bad, increase use cost and after cost.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of protection structure of motorcycle engine gear-shift shaft, subtracted
The stress of light gear-shift shaft, reduces deformation.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of protection structure of motorcycle engine gear-shift shaft, including the gear-shift shaft below engine is arranged on, in addition to
Gear-shift shaft guide holder, the gear-shift shaft guide holder are provided with the mounting hole for being passed through for gear-shift shaft, set in the mounting hole
There are at least two bearings, the bearing inner sleeve is equipped with guide pin bushing, and the gear-shift shaft is located in the guide pin bushing；The gear-shift shaft is oriented to
Seat is each side connected with buffer spring part, and the other end of the buffer spring part is fixed in engine housing.
As the improvement of above-mentioned technical proposal, the buffer spring part is arranged to spring.
As the further improvement of above-mentioned technical proposal, the gear-shift shaft guide holder is each side connected with two bullets
Spring and arrangement symmetrical above and below.
Further improve, the left and right sides of the gear-shift shaft guide holder is provided with an installation journal stirrup, the installation journal stirrup
It is bolted on engine housing, the upper and lower sides of the installation journal stirrup respectively arrange a spring.
Further improve, the guide pin bushing is arranged to two level, and wherein small end is sleeved in the bearing, and big end is connected with installation
Support, the mounting bracket are fixed on engine housing.
Further improve, the bearing is arranged to taper roll bearing, oil sealing is provided with the taper roll bearing.
The beneficial effects of the invention are as follows：Gear-shift shaft guide holder is provided with the mounting hole for being passed through for gear-shift shaft, mounting hole
At least two bearings are inside provided with, bearing inner sleeve is equipped with guide pin bushing, and gear-shift shaft is located in guide pin bushing, is change by least two bearings
Shelves axle improves good support, avoids gear-shift shaft from deforming in the axial direction, bearing also allows the rotation of gear-shift shaft more smoothly, clever
It is living；Gear-shift shaft guide holder is each side connected with buffer spring part, when axial deformation occurs in gear-shift shaft stress, passes through buffering
Spring element is corrected, and further reduces the axial deformation of gear-shift shaft, improves service life.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the decomposition texture schematic diagram of the present invention.
