Abstract
The utility model discloses an engine timing cover, which comprises a water pump turbine housing (1), a cooling water channel (2), a timing cover (3), a cooling water channel outlet (4) and a water-pump shell (7), which the water pump turbine housing (1) is arranged on the upper middle position of the timing cover (3), the cooling water channel (2) is arranged on the two sides of the water pump turbine housing (1), one end thereof is connected with the water pump turbine housing (1), and the other end thereof is connected with a cooling water inlet on a cylinder through the cooling water channel outlet (4) on the timing cover (3), and the cooling water channel (2) is integrated on the timing cover (3) through the casting mode. The engine timing cover with the special structure integrates the turbine housing of a water pump, the cooling water channel and a part of an engine oil pump shell on the time cover through the highly integration of the timing cover, simplifies the design of the cylinder of an engine, reduces the weight of the engine, and reduces the water and oil leakage possibility of the engine.
Description
Technical field
The utility model relates to a kind of engine accessory power rating structure, especially relates to a kind of engine timing cover.
Background technique
Engine timing cover in the past mainly contains following several form: first, timing cover is contained in the front-end face of motor, by increasing the vibration that complicated muscle and suitable layout bolt mounting point reduce motor in the above, the shortcoming that adopts this mode is that motor is compact inadequately; Second, the part of integrated water pump cooling water channel constitutes the into cooling water passage of cylinder body water jacket with water pump cover on the timing cover, the sealing area that adopts this mode to constitute between the two housing sections of cooling water channel is bigger, has increased the possibility that motor leaks; The 3rd, the part of integrated oil pump housing on the timing cover is used for the rotor of placement machine oil pump, adopts this mode timing cover complex structure, casting cost height.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of engine timing cover at problems of the prior art, height by timing cover is integrated, volute and cooling water passage with water pump, the part of oil pump housing is integrated on the timing cover, its objective is the design of simplifying engine cylinder-body, reduce the weight of motor, the reduction motor leaks, the possibility of leakage of oil.
The technical solution of the utility model provides a kind of engine timing cover, comprise water pump volute, cooling water passage, timing cover, cooling water passage water outlet and water pump cover, described water pump volute is arranged in the upper middle position of timing cover, cooling water passage is arranged in the both sides of water pump volute, one end links to each other with the water pump volute, and the other end is connected with cooling water intake on the cylinder body by the cooling water passage water outlet on the timing cover.
Described cooling water passage is integrated on the timing cover by the mode of casting.
Described water pump volute and water pump cover process sealing plane.
A kind of engine timing cover with above-mentioned special construction has the following advantages:
1, the volute of water pump and the cooling water passage that enters cylinder sleeve are integrated on the timing cover, part with the oil pump housing also is integrated on the timing cover simultaneously, be used for the inner and outer rotors of placement machine oil pump, height by this kind timing cover is integrated, simplify the design of engine cylinder-body, reduced the weight of motor.
2, reduced that motor leaks, the possibility of leakage of oil.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a main TV structure schematic representation of the present utility model.
Fig. 2 is a backsight structural representation of the present utility model.
Fig. 3 is a right TV structure schematic representation of the present utility model.
In Fig. 1-3,1: the water pump volute; 2: cooling water passage; 3: timing cover; 4: the cooling water passage water outlet; 5: the oil pump housing that rotor is used is installed; 6: water pump vane and pump shaft; 7: water pump cover; 8: the oil pump internal rotor; 9: the oil pump external rotor; 10: the oil pump housing.
Embodiment
By Fig. 1, Fig. 2, Fig. 3 combination as can be known, water pump volute 1 is arranged in the upper middle position of timing cover 3, cooling water passage 2 is arranged in the both sides of water pump volute 1, mode by casting is integrated on the timing cover 3, one end links to each other with water pump volute 1, the other end is connected with cooling water intake on the cylinder body by the cooling water passage water outlet 4 on the timing cover 3, is that cooling moisture two-way enters cylinder body water jacket.
Water pump volute 1, water pump vane and pump shaft 6 and water pump cover 7 constitute water pump.Whole water route all is to be integrated on the timing cover by the mode of casting, water pump volute 1 and water pump cover 7, the area of contact on cooling water passage water outlet 4 and the cylinder body between the cooling water intake is all bigger, and the plane is not easy to deform, sealing easily, thus the possibility of leaking reduced.The oil pump housing 5 that the installation rotor is used also is integrated on the timing cover 3, with oil pump internal rotor 8 and oil pump external rotor 9 and oil pump housing 10 formation complete oil pump, water pump volute 1 and water pump cover 7 all adopt the mode of processing to process sealing plane, can not need gasket seal just can effectively seal, by so integrated, reduce the quantity of part, reduced the possibility of oil pump leakage of oil.
Claims (3)
1. engine timing cover, comprise water pump volute (1), cooling water passage (2), timing cover (3), cooling water passage water outlet (4) and water pump cover (7), it is characterized in that: described water pump volute (1) is arranged in the upper middle position of timing cover (3), cooling water passage (2) is arranged in the both sides of water pump volute (1), one end links to each other with water pump volute (1), and the other end is connected with cooling water intake on the cylinder body by the cooling water passage water outlet (4) on the timing cover (3).
2. a kind of engine timing cover according to claim 1 is characterized in that: described cooling water passage (2) is integrated on the timing cover (3) by the mode of casting.
