Background
With the increasing severity of global energy crisis and environmental pollution problems, pure electric vehicles are becoming the development direction of future vehicles due to their advantages of low noise, high efficiency, zero emission, etc. The pure electric vehicle can generate torque fluctuation when accelerating, and the instantaneous torque impact is large, and the vibration and the impact can be transmitted to the vehicle frame and further transmitted to the vehicle body and the cab, so that the fatigue damage of parts and the noise in the vehicle are increased. Therefore, the motor is required to be arranged on the frame through a suspension system, the weight of the motor is supported through the suspension system, and the effects of limiting and isolating vibration are achieved.
At present, a uniform design scheme for a drive motor suspension support of a pure electric vehicle does not exist, and different complete vehicle manufacturers generally design the drive motor suspension support according to drive motors of different vehicle types, chassis spaces and the like. The conventional drive motor suspension bracket is usually formed by welding a plurality of steel plates, has high requirement on welding precision, has a complex bracket structure and poor welding consistency, is not suitable for mass production, and is easy to generate fatigue damage. When the distance between the fixed point of the driving motor body and the fixed point of the driving motor suspension frame end is far, the connection between the fixed point of the driving motor body and the fixed point of the driving motor suspension frame end cannot be realized.
Disclosure of Invention
The utility model aims at overcoming when driving motor body fixed point and driving motor suspension frame end fixed point distance is far away, can't realize the defect of the connection of the two under the prerequisite of guaranteeing that driving motor suspension support has sufficient intensity and rigidity, provide a driving motor suspension support.
The technical scheme of the utility model, a driving motor suspension support, includes mount pad, installation boss, mount pad mounting bolt hole, strengthening rib, lightening hole, linking arm, connecting seat and connecting seat mounting bolt hole; a plurality of mounting bosses are arranged on the periphery of the mounting seat, and a mounting seat mounting bolt hole is formed in each mounting boss; the mounting base is provided with a reinforcing rib, and a plurality of lightening holes are formed along the reinforcing rib;
one end of the connecting arm is connected with one side of the mounting seat, the other end of the connecting arm is provided with a connecting seat, and the connecting seat is provided with a connecting seat mounting bolt hole.
Further, the drive motor suspension support is formed by casting QT450-10 integrally.
Furthermore, the number of the mounting bosses is four, and the mounting bosses are respectively arranged on four vertexes outside the mounting seat.
Further, the mounting seat mounting bolt hole is located in the center of the mounting boss.
Furthermore, the mounting seat and the connecting arm are connected in an obtuse angle mode and are in fillet transition.
Furthermore, the lower surface of the connecting seat is a mounting surface, and the mounting seat is perpendicular to the mounting surface.
Further, the connecting seat mounting bolt hole is a long round hole.
The utility model has the advantages that: the utility model discloses on the basis of guaranteeing to have enough intensity and rigidity, weight has been reduced, compact structure satisfies driving motor body fixed point and driving motor suspension car frame end fixed point distance more remote operation requirement.

Description of reference numerals: 1. a mounting seat; 2. mounting a boss; 3. mounting bolt holes on the mounting seat; 4. reinforcing ribs; 5. lightening holes; 6. a connecting arm; 7. a connecting seat; 8. the connecting seat is provided with a bolt hole; 9. the driving motor is suspended.
Detailed Description
As shown in fig. 1, a drive motor suspension bracket comprises a mounting base 1, a mounting boss 2, a mounting base mounting bolt hole 3, a reinforcing rib 4, a lightening hole 5, a connecting arm 6, a connecting base 7 and a connecting base mounting bolt hole 8; a plurality of mounting bosses 2 are arranged on the periphery of the mounting base 1, and a mounting base mounting bolt hole 3 is formed in each mounting boss 2; the mounting base 1 is provided with a reinforcing rib 4, and the mounting base 1 is provided with a plurality of lightening holes 5 along the reinforcing rib 4;
one end of the connecting arm 6 is connected with one side of the mounting seat 1, the other end of the connecting arm is provided with a connecting seat 7, and the connecting seat 7 is provided with a connecting seat mounting bolt hole 8.
The drive motor suspension support is cast and integrally formed.
The number of the mounting bosses 2 is four, and the mounting bosses are respectively arranged on four vertexes outside the mounting base 1.
The mounting seat mounting bolt hole 3 is positioned in the center of the mounting boss 2.
The mounting base 1 and the connecting arm 6 are connected in an obtuse angle mode and adopt fillet transition.
The lower surface of the connecting seat 7 is a mounting surface, and the mounting seat 1 is perpendicular to the mounting surface.
The connecting seat mounting bolt hole 8 is a long round hole.
During assembly, as shown in fig. 2, the mounting seat 1 is fixed on the driving motor body through a bolt, and the connecting seat 7 is fixed on the driving motor suspension 9 through a bolt, so that the connection between the driving motor body and the driving motor suspension 9 is realized.
The utility model discloses driving motor suspension support adopts QT450-10 nodular cast iron casting integrated into one piece, and mount pad 1 and linking arm 6 are the obtuse angle and connect to adopt the fillet transition, guarantee that the linking arm has sufficient intensity.
