Abstract
The utility model discloses a rear mount of an automotive engine. The rear mount comprises a big bushing (1), a small bushing (2) and a connection plate (3), wherein the big bushing (1) and the small bushing (2) are arranged left and right at an interval and the axes of the big bushing (1) and the small bushing (2) are mutually perpendicular, the connection plate (3) is arranged between the big bushing (1) and the small bushing (2), and connects the big bushing (1) and the small bushing (2) into a whole, the connection plate (3) is a punching plate with an approximately C-shaped section, a port of the C-shaped cavity of the connection plate (3) is welded with a flat plate (4), thus the open end of the connection plate (3) is sealed, the left end of the flat plate (4) is connected with the big bushing (1), and the right end of the flat plate (4) is connected with the small bushing (2). The flat plate is welded on the connection plate to seal the open end of the connection plate, so on one hand, the overall strength of the rear mount can be improved, on the other hand the first-order modal frequency of the rear mount can be improved, and the damping and noise reduction effects of the rear mount are improved.
Description
Technical field
The utility model relates to automobile power assembly---and the parts on driving engine, specifically, relate to the structure of back suspension device of engine.
Background technology
On automotive engine, be conventionally provided with that a left side suspends, the right side suspends and rear-suspending, the mounting bracket of driving engine by corresponding position is connected with suspending, and suspends and is connected with vehicle frame, thereby formed left and right, the rear attachment point of driving engine.
Conventionally, back suspension device of engine consists of Large lining, little lining and connecting panel, Large lining and little lining are between left and right every setting, and both axis are mutually vertical, connecting panel is arranged between Large lining and little lining, and Large lining and little lining are connected as a single entity, connecting panel is the pressed sheet of " recessed " shaped sections.
The connecting panel of this " recessed " shaped sections structure, can increase the intensity of connecting panel, improves the effect of damping noise reduction.But along with improving constantly of automotive engine performance requriements, existing structure can not meet vibrations and noise objective requirement.Data show by experiment, and current " recessed " font connecting panel single order model frequency is lower, for 360Hz left and right, not ideal enough to the damping noise reduction effect of back suspension device of engine itself, more than the single order mode frequency requirement of connecting panel reaches 450Hz at present.
Utility model content
The utility model is intended to improve the single order model frequency of connecting panel in back suspension device of engine, thereby improves the own damping noise reduction effect that suspends.
For this reason, the technical scheme that the utility model adopts is: a kind of automobile engine rear suspension, comprise Large lining (1), little lining (2) and connecting panel (3), described Large lining (1) is mutually vertical every setting and axis between left and right with little lining (2), described connecting panel (3) is arranged between Large lining (1) and little lining (2), and Large lining (1) and little lining (2) are connected as a single entity, described connecting panel (3) is the pressed sheet of " recessed " shaped sections, key is: the oral area in " recessed " shape chamber of described connecting panel (3) is welded with flat board (4), thereby the open end of connecting panel (3) is sealed, the left end of described flat board (4) is connected with Large lining (1), the right-hand member of dull and stereotyped (4) is connected with little lining (2).
Be preferably, the middle part of described flat board (4) is provided with lightening grooves (4a), and described lightening grooves (4a) arranges up and down between two parties.Set up lightening grooves, can reduce on the one hand the weight of whole rear-suspending, can also save material on the other hand; Lightening grooves is arranged up and down between two parties, be convenient to guarantee the balance of whole rear-suspending.
Further, (4a) is triangular in shape for described lightening grooves, is convenient to the processing and manufacturing of lightening grooves.
The beneficial effects of the utility model: welding plate on connecting panel, the open end of connecting panel is sealed, make the hatch frame of original connecting panel one end become " mouth " character form structure, the flat board of new welding welds with the two side up and down of little lining, Large lining, connecting panel respectively; Can improve the bulk strength of connecting panel on the one hand, can also improve on the other hand the single order model frequency of connecting panel, checking by experiment, connecting panel single order model frequency after improvement reaches 732Hz, higher than the requirement of existing connecting panel single order model frequency 450Hz, significantly improved the damping noise reduction effect of rear-suspending far away.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
In conjunction with the automobile engine rear suspension shown in Fig. 1, Fig. 2, mainly by Large lining 1, little lining 2 and connecting panel 3, formed.Large lining 1 is connected with subframe by bolt, and little lining 2 is connected with rear suspension bracket by unit bolt nut, and rear suspension bracket is connected with driving engine again.Large lining 1 and little lining 2 are between left and right every setting, and both axis are mutually vertical.Connecting panel 3 is arranged between Large lining 1 and little lining 2, and Large lining 1 and little lining 2 are connected as a single entity.The left end of connecting panel 3 and Large lining 1 welding, the right-hand member of connecting panel 3 and 2 welding of little lining.
Connecting panel 3 is the pressed sheet of " recessed " shaped sections, forms " recessed " shape chamber.The oral area in " recessed " shape chamber of connecting panel 3 is welded with flat board 4, thereby the open end of connecting panel 3 is sealed.Dull and stereotyped 4 left end is connected with Large lining 1, dull and stereotyped 4 right-hand member is connected with little lining 2, dull and stereotyped 4 upper end is connected with the upper side wall of connecting panel 3, and dull and stereotyped 4 lower end is connected with the lower wall of connecting panel 3, makes the hatch frame of original connecting panel one end become " mouth " character form structure.
Preferably, dull and stereotyped 4 middle part is provided with lightening grooves 4a, and lightening grooves 4a arranges up and down between two parties.Lightening grooves 4a is preferably triangle.
