Abstract
The utility model relates to a kind of oil pump cover of strengthening structure that has, and it comprises the oil pump cover that is provided with in the middle rotor fitting seat, and the internal surface of described oil pump cover is formed with oil pump inner cavity chamber; On outer surface corresponding to the oil pump cover of described oil pump inner cavity chamber position, be formed with the stiffening rib that extends to described rotor fitting seat; And near the outer surface of the oil pump cover circumference below described rotor fitting seat, be provided with the oil protection wall of circular arc type, and formed oil groove between described oil protection wall and described rotor fitting seat.The oil pump cover with reinforcement structure of the present utility model is provided with stiffening rib and oil protection wall, and it is simple in structure, has not only significantly strengthened the intensity of oil pump cover, and has kept again internal chamber structure, has also significantly improved in addition the lubrication effect of timing chain.
Description
Technical field
The utility model belongs to the technical field of Automobile Motor Design and manufacture, and in particular, the utility model relates to a kind of oil pump cover of strengthening structure that has.
Background technique
Motor is the core component of automobile, and in the prior art, oil pump cover is not arranged stiffening rib and oil protection wall; and the oil pump cover oil duct chamber thickness of motor is generally 2.5～3.5mm; thinner, because the oil pressure of oil duct chamber is larger, oil pump cover will bear very large oil pressure conventionally; and oil pump inner cavity chamber gathers; generally stiffening rib cannot be arranged, if intensity can not get strengthening, the serious consequences such as stress deformation will be caused; outside timing chain lacks trapped fuel structure in addition, and lubrication effect is bad.
Model utility content
The above-mentioned technical problem existing in order to solve prior art, the purpose of this utility model is to provide a kind of oil pump cover of strengthening structure that has.
To achieve these goals, the utility model provides following technological scheme:
Have an oil pump cover of strengthening structure, it comprises the oil pump cover that is provided with in the middle rotor fitting seat, it is characterized in that: the internal surface of described oil pump cover is formed with oil pump inner cavity chamber; On outer surface corresponding to the oil pump cover of described oil pump inner cavity chamber position, be formed with the stiffening rib that extends to described rotor fitting seat; And near the outer surface of the oil pump cover circumference below described rotor fitting seat, be provided with the oil protection wall of circular arc type, and formed oil groove between described oil protection wall and described rotor fitting seat.
The oil pump cover with reinforcement structure described in the utility model compared with prior art has following beneficial effect:
The oil pump cover with reinforcement structure of the present utility model is provided with stiffening rib and oil protection wall, and it is simple in structure, not only significantly strengthened the intensity of oil pump cover, and kept again internal chamber structure, also significantly improved in addition the utilizability (having improved the lubrication effect of timing chain) of lubricant oil.
Accompanying drawing explanation
Fig. 1 is the structural representation that having of embodiment 1 strengthened the oil pump cover inner side of structure;
Fig. 2 is the structural representation that having of embodiment 1 strengthened the oil pump cover outside of structure;
Fig. 3 is that having of embodiment 1 strengthened the oil pump cover of structure and the structural representation after timing chain assembling.
Embodiment
Below with reference to embodiment and accompanying drawing, the oil pump cover with reinforcement structure described in the utility model is described in further detail.
Embodiment 1
As shown in accompanying drawing 1-2, there is the oil pump cover 2 of strengthening structure described in the present embodiment, it comprises the oil pump cover 2 that is provided with in the middle rotor fitting seat 7, the internal surface of described oil pump cover 2 is formed with oil pump inner cavity chamber 1; On outer surface corresponding to the oil pump cover of described oil pump inner cavity chamber 1 position, be formed with the stiffening rib 3 that extends to described rotor fitting seat; And near the outer surface of the oil pump cover circumference below described rotor fitting seat 7, be provided with the oil protection wall 4 of circular arc type, and formed oil groove 5 between described oil protection wall 4 and described rotor fitting seat 7.Fig. 3 has provided has the oil pump cover of structure of reinforcement and the assembly structure of timing chain 6.Oil pump cover is generally aluminum alloy material.On the basis of oil pump cover, stiffening rib is arranged in to oil pump cover outer surface main oil gallery mouth place and bolt mounting platform place, simultaneously at rotor hole oil pump cover outer surface arranged just beneath oil protection wall, make full use of trapped fuel structure herein, the lubrication effect that increases timing chain has increased intensity herein simultaneously.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or without improving, design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
