Abstract

The utility model provides a timing chain box of an engine and the engine with the timing chain body. The timing chain box is characterized in that a water pump volute chamber is integrated in the timing chain box and is arranged in a water pump housing to form a water pump, and therefore, the water pump volute chamber does not need to be molded in a cylinder block, further a mold for molding the cylinder block is simplified, and enough arrangement space is supplied for other structures integrated in the cylinder block; furthermore, generally, the timing chain box can be made of a cast aluminium material lighter than a cast iron material; and therefore, the water pump volute chamber and the water pump housing are transferred to the timing chain box from the cylinder block and are made of the cast aluminium material, so that the overall weight of the engine can also be reduced.

Description

The timing chain cover of motor and apply the motor of this timing chain cover

Technical field

The utility model relates to engine technology, relates in particular to a kind of timing chain cover of motor and applies the motor of this timing chain cover.

Background technique

In order to realize the cooling of motor, usually need to water pump be set to motor, to provide cooling liquid for motor.Water pump comprises water pump volute chamber and water pump case, and at the water pump of current motor car engine, general and engine cylinder-body integrates, and on engine cylinder-body, offers water pump volute chamber and is combined to form water pump by the water pump case be assemblied on water pump volute chamber.

Due to the complex structure of engine cylinder-body own, its mould development also needs complicated accordingly, if can strengthen the complexity of engine cylinder mould after further being provided with water pump volute chamber, cause complex structure, the cost of motor to improve, and, owing to water pump volute chamber being arranged to the layout that can affect other component on engine cylinder-body, also can increase assembling difficulty; Moreover engine cylinder-body consists of cast iron quality mostly, on cylinder body, integrated water pump also can make the weight of entire engine cylinder body increase the weight of, and then affects the handling of automobile.

The model utility content

In view of problems of the prior art, the utility model provides a kind of timing chain cover of motor and has applied the motor of this timing chain cover.

The technical solution adopted in the utility model is as follows: a kind of timing chain cover of motor comprises:

The timing chain box body;

Be shaped in the water pump volute chamber of described timing chain box body;

Be assemblied in the water pump case of described water pump volute chamber;

And, the chain cover cooling liquid through hole that is shaped in described timing chain box body and described water pump volute chamber is communicated with the cylinder body of described motor.

The utility model also provides a kind of motor, comprises gray iron and timing chain cover as above; Described cylinder body offers cylinder body cooling liquid through hole in the position of the described chain cover cooling liquid of correspondence through hole.

As above visible, in the utility model, water pump volute chamber is integrated in the timing chain cover and forms water pump with the assembling of water pump case, thereby just without at cylinder body, molding water pump volute chamber, thereby can simplify the mould for the moulding cylinder body, and provide enough arrangement space for other structures that are integrated in cylinder body.

And the timing chain cover can be selected the casting aluminium material lighter than cast iron materials usually, therefore, the utility model moves to water pump volute chamber and water pump case the timing chain cover and adopts casting aluminium material from cylinder body, can also make the motor overall weight alleviate.

The accompanying drawing explanation

Fig. 1 is the timing chain cover in the utility model and the decomposition texture schematic diagram of applying the motor of this timing chain cover.

Embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 1, timing chain cover 10 of the present utility model, comprise timing chain box body 2, is shaped in the water pump volute chamber 3 of timing chain box body 2, and water pump case 4 is assemblied in water pump volute chamber 3, and water pump case 4 and water pump volute chamber 3 are combined to form water pump; And, the chain cover cooling liquid through hole 5 that is shaped in timing chain box body 2 and water pump volute chamber 3 is communicated with the cylinder body 1 of motor.

Correspondingly, the utility model also provides a kind of motor, comprises cylinder body 1, cylinder cap (not shown) and is arranged at the above-mentioned timing chain cover 10 of cylinder body 1 one sides; Cylinder body 1 offers cylinder body cooling liquid through hole 6 in corresponding chain cover cooling liquid through hole 5 positions, makes engine coolant enter timing chain cover water pump volute chamber 3 through water pump case 4, by chain cover cooling liquid through hole 5 and cylinder body cooling liquid through hole 6, enters engine cylinder-body 2.

As can be seen here, water pump volute chamber 3 is integrated in timing chain cover 10 and forms water pump with 4 assemblings of water pump case, thereby just without at cylinder body 2, molding water pump volute chamber 3, thereby can simplify the mould for the moulding cylinder body, and provide enough arrangement space for other structures that are integrated in cylinder body.

And timing chain cover 10 can be selected the casting aluminium material lighter than cast iron materials usually, therefore, the utility model moves to water pump volute chamber 3 and water pump case 4 timing chain cover 10 and adopts casting aluminium material from cylinder body 2, can also make the motor overall weight alleviate.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
