Abstract
The utility model relates to a transmission case matching with two types of engines. The transmission case comprises two mounting structures in the same shapes. Each mounting structure comprises a protrusion and a recess; the protrusion of one mounting structure corresponds to a mounting connection hole of one type of engine; the recess of the other mounting structure corresponds to the same type of engine and serves as a mounting and activity space for a part of the engine. The transmission case has the advantages that the requirements on installation of the two different types of engines are met, products are made as universal as possible, and design and production costs of the products are reduced.
Description
Technical field
The utility model relates to a kind of passenger car case of transmission, particularly a kind of case of transmission that mates two kinds of motors.
Background technique
Common same speed changer is during from different Engine Matching, and the shape of connecting end surface need to change according to the difference of motor, namely needs to design different transmission case body structures.But because case of transmission is mo(u)lded piece, casting mould cost is very high, increase by a mold and mean increase great amount of cost, the conformity of production of many molds is also difficult to guarantee simultaneously.
Vehicle is that the red flag board car of CA7301 need to carry the motor that model is CA6GV1, vehicle is that the red flag board car of CA7201 need to carry the motor that model is CA4GC20T, it is just in time contrary that the difference of two kinds of model motors is to install the position of attachment hole and starter motor, the installation attachment hole of CA6GV1 h type engine h upper starter motor under, and the installation attachment hole of CA4GC20T h type engine h at lower starter motor upper.The speed changer of order first two model Engine Matching can not be general.For realizing to greatest extent the generalization of product, reduce product specification and cost of production, need to develop a kind of transmission case body structure of the two kinds of motors of can simultaneously arranging in pairs or groups.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of generalization that can realize to greatest extent product, reduces the case of transmission that mates two kinds of motors of product specification and cost of production.
In order to solve the problems of the technologies described above, the case of transmission that mates two kinds of motors of the present utility model has two mounting structures that shape is identical, and this mounting structure is combined to form by boss and inner fovea part; The lug boss position of one of them mounting structure is corresponding to a kind of installation attachment hole of model motor, and the inner fovea part position of another mounting structure is corresponding to the starter motor of same model motor, as installation and the space of starter motor.
Described inner fovea part is inside recessed curved-surface structure, and this curved-surface structure is installed and space for starter motor provides, and boss is used as the fixedly end face of connecting bolt.
The utility model is according to the concrete mounting structure of two kinds of model motors, mounting structure place reserved on case of transmission designs two concrete structures that shape is close, this structure is combined to form by boss and inner fovea part, wherein inner fovea part is installed and space for starter motor provides, and boss is used as the fixedly end face of connecting bolt.The utility model is when casting, only produce a kind of blank of structure, then reserved installed position on blank, the difference of the engine installation structure mating as required, the corresponding cutting of carrying out, makes this position form two kinds of different mounting structures, thereby meets the installation requirement of two kinds of different model motors, realize to greatest extent the generalization of product, reduced product specification and cost of production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the case of transmission structural representation that mates two kinds of motors of the present utility model.
The case of transmission schematic diagram of the corresponding the first model of Fig. 2 motor CA6GV1
The case of transmission schematic diagram of the corresponding the second model of Fig. 3 motor CA4GC20T
Embodiment
As shown in Figure 1, the improvements that mate the case of transmission of two kinds of motors of the present utility model are to have two mounting structures that shape is identical, and all the other structures are same as the prior art.Each mounting structure is combined to form by boss and inner fovea part, and inner fovea part is inwardly recessed curved-surface structure or the recessed structures that can be used as other shape in part movement space in starter motor; Wherein boss 1 position of first mounting structure is corresponding to the installation attachment hole of the first model motor (model C A6GV1), inner fovea part 4 positions of second mounting structure are corresponding to the starter motor of the first model motor (model C A6GV1), as the space of part in starter motor; Boss 3 positions of second mounting structure are corresponding to the installation attachment hole of the second model motor (model C A4GC20T), inner fovea part 2 positions of first mounting structure are corresponding to the starter motor of the second model motor (model C A4GC20T), as the space of part in starter motor.
During coupling the first model motor, on the boss 1 of case of transmission top mounting structure, the bolt mounting holes 5 of attachment hole is installed in processing corresponding to the first model motor; After the installation attachment hole of the first model motor is aimed at this bolt mounting holes 5, with bolt, is connected, the inner fovea part 4 of second mounting structure of starter motor embedding can complete being connected of case of transmission and this kind of model motor.The obverse and reverse schematic diagram of case of transmission as shown in Figure 2.
During coupling the second model motor, on the boss 3 of case of transmission bottom mounting structure, the bolt mounting holes 6 of attachment hole is installed in processing corresponding to the second model motor; After the installation attachment hole of the second model motor is aimed at this bolt mounting holes 6, with bolt, be connected, the inner fovea part 2 that starter motor embeds first mounting structure can complete being connected of case of transmission and this kind of model motor.The obverse and reverse schematic diagram of case of transmission as shown in Figure 3.
Claims (2)
1. can mate a case of transmission for two kinds of motors, it is characterized in that having two mounting structures that shape is identical, this mounting structure is combined to form by boss and inner fovea part; The lug boss position of one of them mounting structure is corresponding to a kind of installation attachment hole of model motor, and the inner fovea part position of another mounting structure is corresponding to the starter motor of same model motor, as installation and the space of starter motor.
2. the case of transmission that mates two kinds of motors according to claim 1, is characterized in that described inner fovea part is for inside recessed curved-surface structure.
