According to the technical scheme that the utility model provides, described cam controller with axial mechanical position limitation, comprise the controller case, be located at camshaft and switch module in the controller case; The multiple cams assembly is installed on described camshaft, is provided with stage clip between adjacent cam pack; Described cam pack comprises the axle sleeve that is set on camshaft, is set in external cam and cam ring on axle sleeve, the both sides end face of cam ring arranges gear ring, one side end face of external cam is provided with gear ring, one side end face of axle sleeve is provided with gear ring, one side end face gear ring of cam ring and the engagement of the end face gear ring of axle sleeve, the opposite side end face gear ring of cam ring and the engagement of the end face gear ring of external cam; It is characterized in that: the end face gear ring inboard in described external cam is provided with the first deep-slotted chip breaker, in a gear ring inboard, side end face of cam ring, is provided with the second deep-slotted chip breaker, in the opposite side end face gear ring inboard of cam ring, is provided with cannelure; The first guide vane end stop is set in the cannelure of described cam ring, in a side of the first guide vane end stop, spacer pin is set, this spacer pin is arranged in the first deep-slotted chip breaker of external cam; At described sleeve outer surface, the second guide vane end stop is set, an end of the second guide vane end stop is large end, and the other end is small end, and small end is arranged in the second deep-slotted chip breaker of cam ring.
Described the first guide vane end stop is fixed by connector and cam ring.
Described the second guide vane end stop is fixed by connector and axle sleeve.
Described the first guide vane end stop ringwise, arranges the adjustment gear on the outer circumference surface of the first guide vane end stop.
Described switch module comprises a plurality of switches that are arranged on camshaft one side, switch of every group of corresponding installation of cam pack.
The arc surface of the lower surface of described the second large end of guide vane end stop for sleeve outer surface, matching.
The utility model can effectively be avoided because regulating mistake or accident causes security incident, the method of this mechanical position limitation is more flexible, avoided because of each cam work angle scope difference, the complex situations that the relative position of the cannelure of its interior and exterior cam is different, alleviate its mach intensity, improved efficiency.
