Description
Technical field
The utility model relates to a kind of gas distribution system parts of motorcycle engine pressure-reduction starting device, particularly a kind of motorcycle engine decompression starting mandrel.
Background technique
Motorcycle is a kind of convenient traffic tool throughout town and country.Motorcycle engine is the heart of motorcycle, and motorcycle initiating is realized by engine start.Motorcycle engine starts to working state by outage state to be needed to overcome resistance of start realization by starting external force, and the larger corresponding resistance of start of engine horsepower is larger.The Starting mode of motorcycle engine comprises electricity and to start and pin starts, and it is by pressing start button that electricity starts, and is started by starting electrical machinery, pin startup be by the personnel of riding by scrunching starting bar, utilize the dynamic start of pedal.Therefore, for high-powered engine if discharge capacity is at the motorcycle of 200CC and above h type engine h, its not only pin start effort, and electricity to start energy consumption high.For this reason, those skilled in the art adopts the mode arranging pressure-reduction starting device to be overcome through great efforts.Existing decompression member is generally the startup rod member being parallel to camshaft, and Rod end is hidden on a segment base circle working surface of cam.Owing to starting rod member away from camshaft center, larger eccentric moment can be formed in cam axle process, increase the weight of camshaft bearing wearing and tearing., needs decompressor is improved for this reason, thus need to carry out corresponding improvement to startup rod member.
Summary of the invention
The utility model object is for the deficiencies in the prior art, a kind of motorcycle engine decompression starting mandrel is provided, to be applicable to the motorcycle engine pressure-reduction starting device of modified node method, its axle center and camshaft axis coinciding, its eccentric moment in using process, camshaft bearing wearing and tearing are little, and engine noise is little, long service life.
For achieving the above object, the utility model adopts following technological scheme.
A kind of motorcycle engine decompression starting mandrel, comprise circular pin portion, one end, circular pin portion is formed with the control section of cam structure, a part for described cam structure is extended by the cylndrical surface in circular pin portion, and the distance in another part distance axle center, circular pin portion of cam structure is less than the radius of this section of circular pin portion; Another outer end, described bar portion is formed with end face disk, and what this end face disk was provided with at least two circumference uniform distributions stirs pin for what form moment of torsion transmission with centrifugal-block.
Adopt the utility model of preceding solution, for improvement of motorcycle engine pressure-reduction starting device time, rotatingly be engaged in the mesopore of camshaft, camshaft is provided with Self-resetting pressure release pin by pressure release pin, it drives rotation, to be formed the control of pressure release pin diameter to retracted position by the pin of stirring of end face disk by centrifugal-block.Its axle center and camshaft axis coinciding, its eccentric moment in using process, camshaft bearing wearing and tearing are little, and engine noise is little, long service life.
Preferably, the axis of pin and the axis being parallel in circular pin portion is stirred described in.Be convenient to the setting of centrifugal-block torque transfer arrangement, and easy to process, moment of torsion transmission is reliable.
Preferably, the part being less than respective circular bar portion section radius in described cam structure is planar structure.Easy to process, processing cost is low.
Preferred further, described end face disk is formed with mark groove, the direction of mark groove is perpendicular to the plane on described cam structure.Identify during convenient installation, improve make efficiency.
Preferred further, the diameter in the stage casing in described circular pin portion is less than circular pin portion diameter.Effectively can reduce the surface friction drag started between mandrel and camshaft matching hole, play certain effect keeping lubricant oil simultaneously, increase the service life.
The beneficial effects of the utility model are, for improvement of the motorcycle engine pressure-reduction starting device of structure, its axle center and camshaft axis coinciding, its eccentric moment in using process, camshaft bearing wearing and tearing are little, and engine noise is little, long service life.
