Description
Technical Field
The invention relates to the technical field of automobile power assembly suspension, in particular to a combined structure of an electric power assembly suspension and a bracket.
Background
the power assembly suspension system mainly plays the roles of connecting the vehicle body frame and the power assembly, supporting the power assembly, limiting the motion of the power assembly and obstructing and attenuating the vibration of the power assembly. The electric power assembly has larger torque and quick change response, so the arrangement form, the part form, the assembly mode and the like of the suspension system are different from those of the traditional fuel vehicle.
The common combined structure of the suspension and the support of the electric power assembly in the prior art has poor torsion resistant effect, low support mode and rigidity, high cost, inconvenient assembly and the like.
disclosure of Invention
The utility model aims at providing a integrated configuration of electronic power assembly suspension and support compares with common electronic power assembly suspension and support, and its characteristics lie in antitorque effectual, and support mode and rigidity are high, and durable and NVH performance is too hard, and whole scheme occupation space is little, economizes the material and falls originally, and the while location is accurate, the assembly of being convenient for.
A combined structure of an electric power assembly suspension and a bracket comprises a sheet metal bracket and an electric power assembly suspension assembly, wherein the sheet metal bracket is connected to the electric power assembly suspension assembly and a frame;
a baffle is arranged on the metal plate bracket;
The electric power assembly suspension assembly comprises a suspension bracket and a suspension bushing, and the suspension bushing is pressed into the suspension bracket;
a rubber main spring and a limiting block are arranged in the suspension bushing.
Preferably, the rubber main spring is X-shaped.
Preferably, the baffle plate is provided with a circular groove.
Preferably, a plurality of staggered reinforcing ribs are arranged on the suspension bracket.
Preferably, a plurality of independent limiting blocks are arranged in the rubber main spring.
The utility model has the advantages that:
1. The suspension bushing is pressed on the suspension support, the rubber main spring is X-shaped, the torque action direction is provided with a separate limiting block, the torsion resistance effect is good, and the durability and NVH performance are good.
2. The suspension support is large in longitudinal size, compact in structure, capable of lengthening the force arm, reducing stress of the suspension bushing, capable of guaranteeing self mode and good in NVH performance.
3. The separation blade is welded at the mounting position of the metal plate support, so that the metal plate support is convenient to mount and accurate in positioning.

Detailed Description
Referring to fig. 1 to 7, a combined structure of an electric power assembly suspension and a bracket includes a sheet metal bracket 1 and an electric power assembly suspension assembly 2, the sheet metal bracket 1 is connected to the electric power assembly suspension assembly 2 and a frame, and the electric power assembly suspension assembly 2 is connected to the sheet metal bracket 1 and a speed reducer;
A baffle piece 10 is arranged on the sheet metal bracket 1;
The electric power assembly suspension assembly 2 comprises a suspension bracket 20 and a suspension bush 21, wherein the suspension bush 21 is pressed into the suspension bracket 20;
A rubber main spring 22 and a stopper 23 are provided in the suspension bush 21.
Preferably, the rubber main spring 22 is X-shaped.
Preferably, the baffle plate 10 is provided with a circular groove.
Preferably, a plurality of staggered reinforcing ribs are arranged on the suspension bracket 20.
Preferably, a plurality of individual stoppers 23 are provided in the rubber main spring 22.
The utility model discloses a theory of operation:
referring to fig. 1 to 7, a sheet metal bracket 1 is formed by stamping and welding a sheet metal, two planes connected to the electric power assembly suspension assembly 2 are welded with a baffle piece 10, and the baffle piece 10 has guiding and precise positioning functions along with the shape of the installation position of the electric power assembly suspension assembly 2.
Suspension support 20 is formed by aluminum alloy die-casting, and the great suspension bush atress that reduces of longitudinal dimension has certain thickness and the crisscross higher structural mode of assurance of strengthening rib, has reduced the material quantity as far as, reduce cost, lightweight more.
The rubber main spring 22 in the suspension bush 21 is X-shaped, the torque action direction is provided with the independent limiting block 23, and the fatigue durability problem caused by the excessive stretching of the rubber main spring 22 is avoided while the vibration isolation and damping performance is ensured by proper rigidity.
