Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, belongs to scope.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the feel lifting device structural representation of motorcycle engine provided by the present invention; Fig. 2 is motorcycle engine speed transmission drum structural representation provided by the present invention; Fig. 3 is that schematic diagram is opened at motorcycle engine speed transmission drum A-A place provided by the present invention.
A kind of motorcycle engine provided by the present invention, comprise speed transmission drum 1 and selector fork 2, sleeve pipe 21 socket on described selector fork 2 is arranged on described speed transmission drum 1, also comprise feel lifting device, described feel lifting device comprises the through hole 34 being arranged at described speed transmission drum 1 neutral section place and the blocking aperture 31 being arranged at described sleeve pipe 21 inwall, is provided with elastic barrier part in described through hole 34.
Wherein, it will be appreciated by persons skilled in the art that the gearshift principle of motorcycle engine is that speed transmission drum 1 rotates, thus drive selector fork 2 to move, and then realize cooperatively interacting between different gear, realize gearshift.
When speed transmission drum 1 rotates, thus when driving selector fork 2 to move, when the sleeve pipe 21 of selector fork 2 arrives neutral section place, the through hole 34 being arranged at neutral section place is communicated with blocking aperture 31, because elastic barrier part has certain elasticity, therefore after through hole 34 is communicated with blocking aperture 31, the top of elastic barrier part enters in through hole 34, to increase the resistance between sleeve pipe 21 and speed transmission drum 1, when other gear hung by needs, first need external force to overcome this resistance, make elastic barrier part under the pressure of sleeve pipe 21, return in through hole 34.This just makes motorcycle engine have obvious operating experience when hanging neutral, thus effectively avoids the situation of accidental shifting position to occur, and therefore also improves the Security of friction car driving and reduces the generation occurring contingency situation.
Certainly, when the top of elastic barrier part enters after in through hole 34, when operator hang other gear again, obviously can feel that there is larger resistance, while ensureing that its neutral place has stronger operating experience, also need to avoid resistance excessive thus cause hanging the situation when failed, therefore in the present invention one specific embodiment, the bottom surface that described blocking aperture 31 and described speed transmission drum 1 are fitted is provided with to the oblique type working surface in described blocking aperture 31.In the course of the work, oblique type working surface effectively can reduce the resistance between elastic barrier part top, and the inclined-plane making elastic barrier part top can follow oblique type working surface reclaims, thus enters completely in through hole 34.
