Abstract
The utility model discloses an upper cover of an intake manifold assembly. The upper cover of the intake manifold assembly comprises a shell, wherein the edge of the shell outwards extends to form a connecting outer edge, a transition fillet is arranged at the position of connection between the shell and the connecting outer edge, and the radius of the transition fillet ranges from 4 mm to 5 mm. According to the upper cover of the intake manifold assembly, due to the fact that the transition fillet of the upper cover of the intake manifold assembly is arranged and is enlarged, the structure at the position of the transition fillet is improved, stress concentration is reduced, strength of a transition area of the upper cover of the intake manifold assembly is improved, casting quality of the upper cover of the intake manifold assembly is improved, cracks which appear in the casting mold release process are eliminated, and the rate of qualified products is increased.
Description
Technical field
The utility model belongs to engine intake duct technical field, relates in particular to a kind of upper cover of inlet manifold assembly.
Background technique
Inlet manifold assembly is one of critical component of motor, for the each cylinder of motor provides sufficient mixed gas uniformly, affects the overall operation situation of motor.At present, the upper cover of inlet manifold assembly easily cracks in casting knockout course, thereby cause inlet manifold assembly to occur leakage phenomenon, and this crackle can deepen along with the accumulation of the running time of motor to strengthen, thereby further affect the service behaviour of motor.
Model utility content
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the upper cover that proposes a kind of inlet manifold assembly.
The purpose of this utility model will be achieved by the following technical programs:
A upper cover for inlet manifold assembly, comprises a housing, and the edge of described housing is outward extended with and connects outer, and the joint between described housing and described connection outer is provided with knuckle.
Preferably, the upper cover of above-mentioned a kind of inlet manifold assembly, wherein: the radius of described knuckle is 4mm～5mm.
Preferably, the upper cover of above-mentioned a kind of inlet manifold assembly, wherein: described connection outer is provided with mounting hole.
Preferably, the upper cover of above-mentioned a kind of inlet manifold assembly, wherein: the upper cover of described inlet manifold assembly is installed in motor.
Outstanding effect of the present utility model is: the upper cover of a kind of inlet manifold assembly of the present utility model is by arranging and strengthen the knuckle of upper cover of inlet manifold assembly, improve the structure at knuckle place, alleviating stress concentrates, improve the intensity of the upper cover transition region of inlet manifold assembly, thereby improve the castability of the upper cover of inlet manifold assembly, eliminate the appearance of crackle in casting knockout course, improve accepted product percentage.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
