Specific implementation mode

The utility model is described in detail below in conjunction with attached drawing：

Embodiment one

A kind of novel electricity generator hitching leg structure as shown in Figure 1, 2 includes with 4 He of protecgulum for being located in engine block 7 Rear cover 5, protecgulum 4 include that first upwardly extended hanging feet 1 and the second hanging feet 2 for extending downwardly, and rear cover 5 includes the extended downwardly Three hanging feets 3,1,2,3 end of the first, second, third hanging feet are correspondingly provided with the first, second, third mounting post 11,21,31 respectively, There is the first mounting surface 13,21 left side of the second mounting post to have the second mounting surface 23, third mounting post in first mounting post, 11 left side 31 left side planes are overlapped with the second mounting surface 23.First, second hanging feet 1,2 is individually connect with protecgulum 4, third hanging feet 3 and rear cover 5 Individually connection is then independently fixedly installed in by installation bolt on automobile engine or its holder extended.Make each extension The stress of foot more disperses, and structure is more stablized.

In the present embodiment, the first, second mounting surface 13,23 is placed in the perpendicular two where 7 axis of engine block Side.The space structure in automobile engine nacelle can be preferably adapted to by not being located at the mounting post of same mounting surface so that not needed The special mounting plane for installing entire generator is processed, difficulty of processing is reduced.Second, third mounting post 21,31 In same second mounting surface 23 so that two mounting post installation forms for being similarly positioned in lower section are simpler, force structure is more preferable.The One, the second mounting surface 13,23 perpendicular both sides where 7 axis of engine block that are placed in are more conducive to the excellent of mechanical structure Change.

In the present embodiment, the first, second, third mounting post 11,21,31 respectively further comprises the first, second, third mounting hole 12、22、32。

First, second, third mounting hole 12,22,32 is used for across bolt fixed generator.

In the present embodiment, 12,22,32 axis of the first, second, third mounting hole is each perpendicular to 7 axis institute of engine block Perpendicular.Have following excellent with generator shaft mounting hole disposed in parallel, vertical mounting hole in compared with the prior art Point：First, on engine bent axle and generator shaft connecting pin no longer need accurate allowance control with by mounting hole top surface with Engine mounting face contacts to ensure the concentricity of bent axle and generator shaft so that the production and processing required precision of generator is dropped Low, assembly is also simpler；Secondly, can compared with the prior art have preferably by turning to tangent mounting hole with generator shaft Stress performance and fatigue behaviour.

In the present embodiment, 1,2,3 horizontal cross-section of the first, second, third hanging feet by close to 7 end of engine block outward gradually It is small.Gradually small horizontal cross-section reduces the weight of generator while ensureing that excellent force structure improves the service life, lighter Weight is further reduced the stress of each mounting post reducing while vehicle weight energy-saving and emission-reduction, to further extend its use Service life.

In the present embodiment, the first, second, third mounting post 11,21,31 is cylinder.

Cylindrical mounting post is easy to process and allowance control, while in each mounting hole and cylindrical-concentric from each mounting hole Center is to each cylindrical edge apart from equal.Force structure is more preferable.

In the present embodiment, 11 horizontal length of the first mounting post is less than second, third mounting post 21,31 horizontal lengths.

Second, third mounting post 21,31 also needs to support generator itself while bearing generator operation torque Gravity.Therefore need the horizontal length of 11 bigger of opposite first mounting post for ensureing its intensity and service life.

Embodiment two

Technical solution described in the present embodiment is approximate with embodiment one, as shown in Figure 3,4, the difference is that：

In the present embodiment, functional layer 6 is equipped in the first mounting hole 12, the second mounting hole 22, third mounting hole 32.Because of spiral shell Bolt installation will necessarily between bolt and mounting hole leaving gap, therefore be further accurately positioned and reduce vibration in some needs Occasion, by functional layer 6 improve installation accuracy and reduce vibration.

In the present embodiment, functional layer 6 includes positioned at a pair of semicircle rubber bearing bush 61 of inside and set on rubber bearing bush 61 With the lantern ring 62 between the first mounting hole 12, the second mounting hole 22,32 inner wall of third mounting hole.

The vibration that 61 one side of rubber bearing bush generates when can absorb generator operation by the elasticity of its own；Another party Face, with certain thickness come the gap between installation bolt and inner wall of the hole installing of preventing, to improve accuracy.It is installing When, the diameter after the combination of rubber bearing bush 61 can be slightly less than the outer diameter of installation bolt so that installation bolt, which passes through, cuts rubber axis Watts 61 form completes installation, ensures that rubber bearing bush 61 and installation bolt are transferred to pair while fitting closely by installation bolt The extruding of rubber bearing bush 61 forms lasting elastic stress of the rubber bearing bush 61 to installation bolt, which can make pair The assimilation effect of the operational vibration of generator is more preferable, and installation effect is also more firm.Set on inner wall of the hole installing and rubber bearing bush 61 it Between lantern ring 62 rubber bearing bush 61 is easily dismounted with respect to mounting hole so that entire novel electricity generator hanging feet knot Vulnerable part only has the functional layer 6 of low cost being conveniently replaceable, the installation maintenance after convenience and cost control in structure.

In the present embodiment, there is lantern ring 62 axial opening, opening to be equipped with adjusting bolt 63.

On the one hand lantern ring 62, which is adjusted, by adjusting bolt 63 can meet the different of different size generators installs On the other hand the requirement of bore dia keeps lantern ring 62 straight after rubber bearing bush 61 has certain wear extent by adjusting adjusting bolt 63 Diameter, which is reduced, can continue to keep the close connection between rubber bearing bush 61 and installation bolt, ensure its service life.

Above example is only described preferred embodiments of the present invention, not to the structure of the utility model Think and range is defined, without departing from the design concept of the present utility model, ordinary people in the field is new to this practicality The all variations and modifications that the technical solution of type is made each fall within the scope of protection of the utility model, the utility model request The technology contents of protection have all been recorded in detail in the claims.
