Abstract
The utility model discloses a kind of electric booster steering device gear box casing, it is three-chip type shell structure, it includes gear side body, motor side body and intervalve independently, and gear side body pressure is located at one end of the intervalve, the other end of the motor side body pressure located at the intervalve.Electric booster steering device gear box casing is split as three-chip type by the utility model, so that the difficulty of casting is reduced, while the application of middle steel pipe reduces total cost of production.In addition, passing through the strict control of the press-in cooperation technique to three-chip type housing, such as stroke, centering, it is ensured that the requirement of the axiality of whole gear box casing, so as to ensure the function and performance indications of electric booster steering device.
Description
Technical field
The utility model is related to automobile electric booster steering system technical field, more particularly to a kind of electric booster steering device
Gear box casing.
Background technology
At present, electric booster steering device gear box casing is based on single piece type aluminum enclosure, as shown in Figure 1.For single piece type
Aluminum enclosure, usual shell length is 600mm, and its major advantage is：First, the axiality or uniformity of two sections of product are easier to protect
Card, second, point have for housing mid-section the mount point such as established angle and wire harness, heat shield design requirement straight forming more
It is convenient.But, there is also the shortcoming that casting difficulty is big, production cost is high for single piece type aluminum enclosure.
Utility model content
There is provided a kind of new electric booster steering device tooth for the problem of the utility model exists for prior art and deficiency
Take turns tank shell.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of electric booster steering device gear box casing, and its feature is, it is three-chip type housing
Structure, it includes gear side body, motor side body and intervalve independently, and gear side body pressure is located at the intervalve
One end, the motor side body pressure located at the intervalve the other end.
It is preferred that the intervalve is middle steel pipe.
It is preferred that the gear side body is gear side aluminum enclosure.
It is preferred that the motor side body is motor side aluminum enclosure.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, produce the utility model it is each compared with
Good example.
Positive effect of the present utility model is：
Electric booster steering device gear box casing is split as three-chip type by the utility model, so as to reduce casting
Difficulty, while the application of middle steel pipe reduces total cost of production.In addition, passing through the press-in cooperation technique to three-chip type housing
Strict control, such as stroke, centering, it is ensured that the requirement of the axiality of whole gear box casing, so as to ensure electric boosted
The function and performance indications of steering gear.
Brief description of the drawings
Fig. 1 is the structural representation of one piece housing.
Fig. 2 is the structural representation of the electric booster steering device gear box casing of the utility model preferred embodiment.
Fig. 3 shows for the structure of steel pipe in the middle of gear side body and motor the side body press-in of the utility model preferred embodiment
It is intended to.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that retouched
The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made all belongs to
The scope protected in the utility model.
As shown in Figures 2 and 3, the present embodiment provides a kind of electric booster steering device gear box casing, and it is three-chip type housing
Structure, it includes gear side aluminum enclosure 1, motor side aluminum enclosure 2 and middle steel pipe 3 independently, and the gear side aluminum enclosure 1 is pressed
Located at one end of the middle steel pipe 3, the other end of the motor side aluminum enclosure 2 pressure located at the middle steel pipe 3.
It is more than 600mm especially in more than 700mm gear box casing, or relative to one piece housing for length
In the case of same length, while in the case of design adjustment can be done to established angle, wire harness, heat shield mount point etc., it is considered to
Gear box casing is optimized to three-chip type design by two aspects below：On the one hand, for the consideration of manufacturing process, three are split into
Afterwards, the difficulty of casting is reduced, while the application of middle steel pipe reduces resulting cost.On the other hand, by three
The strict control of the press-in cooperation technique of piece sandwich type element, such as stroke, centering, are shown in Fig. 3, it is ensured that whole gear box casing
The requirement of axiality, so as to ensure the function and performance indications of electric booster steering device.
Although the foregoing describing embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or repair to these embodiments on the premise of without departing substantially from principle of the present utility model and essence
Change, but these changes and modification each fall within protection domain of the present utility model.
