Abstract
A pressure-reducing device for vertical engine of motorcycle relates to a vertical engine of motorcycle. The pressure-reducing device for vertical engine of motorcycle is provided with a simple structure, reduced discharge and impulse force caused by the reverse rotation of motorcycle engine with the foot starting system, against the shortages of that the impulse force caused by engine reverse rotation hurts the electrical starting device and the foot starting device and the foot starting hurts people, in the existing situations of enlarged discharge, enlarged transmitted power and enlarged torsion. The technique scheme is that: the air inlet cam on the vertical engine 1 of motorcycle and the cam shaft 6 arranged between the spherical bearings are equipped with a pressure-reducing valve 5 and a locating sleeve 10; the two holes of the support 15 of the check plate 4 are respectively arranged on the two valve rocker shafts 3.
Description
One, technical field
The utility model technology relates to the motorcycle vertical engine, the decompressor of the motorcycle vertical engine that especially a kind of big discharge capacity, band pin start.
Two, background technique
Existing motorcycle engine discharge capacity is strengthened gradually by little, and horizontal machine 70 types change 90, change to 100,125 types by 90 types; Vertical machine changes 150,175,200 types by 125 types.Increasing along with engine displacement, motor transmitted power, moment of torsion strengthen many, the impact force that engine inversion brings, related components such as the startup of major injury electricity, pin start-up system and transmission system, bring impact force when particularly pin starts, be easy to the user is damaged.In big discharge capacity, have on the motorcycle engine that pin starts system decompressor be installed, and reduction valve opens is that the motor of intake valve belongs to blank on the motorcycle engine at home.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, reduces big discharge capacity, has the decompressor that the counter-rotating of pin start-up system motorcycle engine brings the motorcycle vertical engine of impact force.
The technological scheme that the purpose of this utility model adopted is, be equipped with reduction valve and setting sleeve on the camshaft between intake cam on the motor and the installation ball bearing, two holes are contained in respectively on two valve lever pins on the support of check plate, the cylindrical of its reduction valve has relief valve body one end of positive stop lug boss that eccentric boss is arranged, device had return spring and roller in interior circle was fluted, the upper end of check plate has the support intermediate hole of rectangular positioning plate that the connecting plate of rivet shape is housed, the rivet that is of connecting plate is with spring guideway and the plate of dialling that has two protruding angles outward, the spring guideway is around with Returnning spring, the Returnning spring two ends are stuck on the rectangular positioning plate in support upper end and dial on protruding angle of plate, and a rectangular positioning plate in protruding angle and support upper end dialling plate is adjacent, another protruding angle is leaned on mutually with the cylindrical positive stop lug boss of relief valve body.
The utility model, the cylindrical positive stop lug boss of relief valve body and eccentric boss angle are 2-10 °.
The utility model working principle: engine cut-off and each the startup in the failure procedure, engine piston is when the no show top dead center causes engine inversion in compression stroke, camshaft drives the reduction valve counter-rotating, the eccentric boss jack-up of one end of reduction valve valve rocker, engine valve is opened, reduce the engine cylinder internal pressure, reduce the impact force that engine inversion brings; When under motor, often turning round, camshaft drives reduction valve and rotates, because the cylindrical positive stop lug boss of relief valve body leans on mutually with a protruding angle of dialling plate of check plate, check plate position-limiting action and reduction valve have only unidirectional spinfunction, reduction valve is accurately positioned in a certain position by check plate, reduction valve is effectively separated with valve rocker, thereby keep characteristics such as the original power of motor, moment of torsion and engine speed constant.
The utlity model has simple and compact for structurely, fabrication and installation are convenient; The impact force of bringing when reducing engine inversion has been protected related components on the motor, prolongs motor working life, makes engine performance more reliable; Make the big displacement motorcycle engine can the installation foot start-up system, as usual can ato unit under the situation of motor storage battery short of electricity.The motor rebounding force reduced when the user started at pin, had well protected the user; Make things convenient for the user to start to be equipped with the big displacement motorcycle engine of pin start-up system, wait characteristics when user's pin is started more easily, freely.
