Description
Technical field
The utility model belongs to motorcycle field, particularly relates to a kind of motorcycle engine.
Background technique
As everyone knows, cowl hood, cylinder head, cylinder block and crankcase body are the vitals of motorcycle engine, cylinder head, cylinder block and crankcase body are linked together by the stud that several lengthen, and one end of stud is threaded with the tapped hole on crankcase body, the other end of this stud is connected with nut thread.And, in the circular groove of cowl hood bottom surface, seal ring is housed, the cross section of seal ring is " convex " font, its projection snaps in circular groove, the bottom surface of seal ring and the end face of cylinder head are close to, leave slight clearance between the bottom surface of cowl hood and the end face of cylinder head, and cylinder head and cowl hood are tightened together by two connecting bolts.
Meanwhile, be provided with a retainer in cylinder head, these two parts are split-type structural, and retainer is located by locating stud and cylinder head, and are fastened by bolts together.Further, the minimum separable outside retainer and between cylinder head inwall is 3-5mm.The pitman arm shaft that cylinder head is arranged side by side built with two, a rocking arm contacted with camshaft overhead cam is set with in the middle part of this pitman arm shaft, and pitman arm shaft two ends are arranged in the horizontal mounting hole on retainer, there is between pitman arm shaft and horizontal mounting hole the gap of trace.Two pitman arm shafts are all bolted on retainer, and the bolt on a pitman arm shaft is near timing sprocket, and the bolt on a pitman arm shaft is away from timing sprocket.
The main defect of prior art is as follows:
1, existing structure cannot obtain fully comprehensively lubrication to parts such as rocking arms, needs specialized designs lubricant oil way, and makes full use of existing structure, reach the object of simplified structure:
2, because stud is longer, and engine assembly on motorcycle after limited space, when engine maintenance and maintenance, usually motor is first pulled down from motorcycle by its needs, then could service engine, operates very inconvenient;
3, existing structure relies on the compression of seal ring and distortion to realize sealing, and will lose efficacy, thus lose sealing function after seal ring is overly compressed.
4, because retainer and cylinder head are split-type structural, and be fastened by bolts together, so not only need the junction plane processing retainer and cylinder head, increase the parts such as locating stud and bolt, thus increase manufacture cost, and structural strength is not high, easily produces distortion and shake.
5, because camshaft is by after the downward pulling force of timing chain, trace can be there is and swing in camshaft in vertical plane, its one end near timing chain can be downward-sloping, the way of contact of the rocking arm on pitman arm shaft and camshaft will be caused like this to be point cantact, noise will be produced like this, and aggravate the wearing and tearing of rocking arm and camshaft, reduce the working life of these two parts.
