Abstract
The utility model discloses a kind of motor vehicular engine integral cam shaft bearing support, it has camshaft bearing seat body (1), pitman arm shaft mounting hole (2), stay bolt hole (3) and camshaft bearing mounting hole (5) are set thereon, camshaft bearing mounting hole (5) is an overall structure, with camshaft bearing seat body (1) be an integral body.The utility model does not change the agent structure of existing camshaft for motorcycle engine bearing support, be the overall structure of time processing moulding just with the camshaft bearing mounting hole on it, make the camshaft for motorcycle engine bearing chamber all on camshaft bearing bush seat, this structural rigidity is strengthened, make camshaft bearing stressed at work evenly, solved the frangible problem of cam assembly bearing, thereby made the bearing life in the cam assembly obtain lengthening.The noise of cylinder head has also obtained bigger reduction simultaneously, has improved the reliability of motor, has reduced the breakdown in the motor rate.
Description
Technical field
The utility model belongs to the motorcycle engine mounting assembly.Relate generally to a kind of motor vehicular engine integral cam shaft bearing support.
Background technique
The camshaft bearing bush seat of the pedal motorcycle motor of present domestic most 125 discharge capacities, as shown in Figure 1, has camshaft bearing seat body 1, it is provided with pitman arm shaft mounting hole 2, stay bolt hole 3 and camshaft bearing mounting hole 4 is set, the split-type structural of camshaft bearing mounting hole 4 for constituting by upper and lower semicircle, first garden is on camshaft bearing seat body 1, and second garden is the part of cylinder head on cylinder head.Two and half gardens form bearing chamber by bolt together up and down.Two and half garden work in-processes of this structure, it is separate machined, when so two and half gardens lump together, be easy to occur the situation of two and half garden decentraction, therefore in motor proper functioning cam axle bearing discontinuity, even be subjected to shearing force, cause the bearing in the cam assembly to break, and noise is bigger.This problem is a general problem in whole motorcycle industry, and the user is more outstanding to this reflection.
Summary of the invention
The purpose of this utility model provides a kind of motor vehicular engine integral cam shaft bearing support, makes it reduce the stressed of camshaft bearing, improves the camshaft bearing working environment, thereby improves the reliability of motor.
The purpose of this utility model can adopt following technological scheme to realize: it has the camshaft bearing seat body, pitman arm shaft mounting hole, stay bolt hole and camshaft bearing mounting hole are set thereon, wherein the camshaft bearing mounting hole is an overall structure, with the camshaft bearing seat body be an integral body.
By last structure as can be seen, the utility model does not change the agent structure of existing camshaft for motorcycle engine bearing support, be the overall structure of time processing moulding just with the camshaft bearing mounting hole on it, make the camshaft for motorcycle engine bearing chamber all on camshaft bearing bush seat, this structural rigidity is strengthened, make camshaft bearing stressed at work even, solved the frangible problem of cam assembly bearing, thereby make the bearing life in the cam assembly obtain lengthening.The noise of cylinder head has also obtained bigger reduction simultaneously, has improved the reliability of motor, has reduced the breakdown in the motor rate.
Description of drawings
Accompanying drawing 1 is existing camshaft for motorcycle engine bearing support.
Accompanying drawing 2 is a structural representation of the present utility model.
Accompanying drawing 3 is the utility model and motorcycle cylinder head connection diagram.
Among the figure: 1, camshaft bearing seat body, 2, the pitman arm shaft mounting hole, 3, the stay bolt hole, 4, the camshaft bearing mounting hole, 5, the camshaft bearing mounting hole, 6, motorcycle cylinder head.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 2, the utlity model has camshaft bearing seat body 1, pitman arm shaft mounting hole 2, stay bolt hole 3 and camshaft bearing mounting hole 5 are set thereon, camshaft bearing mounting hole 5 is an overall structure, with camshaft bearing seat body 1 be an integral body.
As shown in Figure 3, the utility model is installed in engine cylinder head 6 tops, is fixed together with 4 bolts and cylinder head 6.Owing on the camshaft bearing bush seat complete bearing chamber is arranged, so the camshaft bearing of motorcycle engine is directly put into camshaft bearing bush seat.
Claims (1)
