Abstract
The invention discloses a rear suspension damping device for a motor of an electric automobile. The damping device comprises a damping bracket and a damping cushion which is arranged on the damping bracket, wherein the damping bracket is assembled on the frame of the automobile; the damping cushion comprises an inner sleeve, an outer sleeve and a vibration isolator which is arranged between the inner sleeve and the outer sleeve; after being vulcanized, the inner sleeve and the outer sleeve are connected into a whole through the vibration isolator; both the inner sleeve and the outer sleeve are made of 20# cold-drawn seamless steel pipes of which the surfaces are phosphatized; and the vibration isolator is made of a rubber material with good vibration isolation and vibration reduction effects. The rear suspension damping device for the motor of the electric automobile has a simple structure, high damping performance and high durability, and is convenient to produce, manufacture and assemble.
Description
Technical field
The present invention relates to a kind of electric vehicle parts, especially relate to suspending shock-absorbing device behind a kind of motor in electric automobile.
Background technique
At present, the automobile power suspension system is aimed at that traditional engine automobile develops more, and the drive characteristic of its internal-combustion engine obviously is different from the drive characteristic of electric vehicle motor, and motor speed rises to rated speed from 0r/min, frequency is a continually varying, the idling phenomenon of no traditional combustion engine.Power system of electric automobile is to be made of motor and retarder, be installed on the subframe by the motor suspension system, motor is a main vibration noise excitation source, when running up comprising motor, because the uneven exciting force that produces of rotor quality, the excitation that the fluctuation of electromagnetic torque produces, and the fluctuation of Uneven road and adhesion causes the torsional oscillation of motor, the size of vibration noise directly has influence on the travelling comfort of car load and the working life of motor, traditional motor vibration insulating system ubiquity complex structure that suspends, the shortcoming that effectiveness in vibration suppression is bad.
Summary of the invention
The object of the present invention is to provide suspending shock-absorbing device behind a kind of motor in electric automobile, suspending shock-absorbing device has simple in structure behind the described motor in electric automobile; Practical, endurance quality is high and the characteristics of good damping result.
The objective of the invention is to be achieved through the following technical solutions:
Suspending shock-absorbing device behind a kind of motor in electric automobile, it comprises shock absorber bracket and is installed on damping pad on the shock absorber bracket, wherein, described damping pad comprises interior cover, overcoat and is arranged at vibration isolator between the inside and outside cover that described inside and outside cover connects as one by vibration isolator after vulcanizing.
Described vibration isolator is that the rubber material of the good vibration isolation and damping effect of tool is made.
Described inside and outside cover is made through parkerized 20# cold drawing seamless pipe by the surface.
Beneficial effect of the present invention is that suspending shock-absorbing device is not only simple in structure behind the described motor in electric automobile, is convenient to manufacture, and is convenient to assembling, and anti-vibration performance is superior, the endurance quality height.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of suspending shock-absorbing device behind the motor in electric automobile of the present invention,
Fig. 2 be among Fig. 1 damping pad A-A to sectional drawing.
Among the figure:
1, shock absorber bracket; 11, supporting frame; 12, connecting tube; 2, damping pad; 21, interior cover; 22, vibration isolation rubber body; 23, overcoat.
Embodiment
Please refer to Figure 1 and Figure 2, Fig. 1 is the structural representation of suspending shock-absorbing device behind the motor in electric automobile of the present invention, Fig. 2 be among Fig. 1 damping pad A-A to sectional drawing.
In present embodiment, suspending shock-absorbing device behind a kind of motor in electric automobile, it comprises the shock absorber bracket 1 that is assemblied on the automobile frame and is installed on damping pad 2 on the shock absorber bracket 1, described shock absorber bracket 1 by two supporting brackets 11 and two connecting tubes 12 through it by punch and weld, and it is provided with mounting ring, and the surface is through the antirust processing of electrophoretic paint; And can satisfy 144 hours salt spray tests, described supporting bracket 11 adopts Q235 to make, described connecting tube 12 adopts the 20# seamless steel pipe to make, described damping pad 2 comprise in the cover 21, overcoat 23 and be arranged in the cover 21 and overcoat 23 between vibration isolation rubber body 22, cover 21 and overcoat 23 connect as one by vibration isolation rubber body 22 after vulcanizing in described, and cover 21 and overcoat 23 are made through parkerized 20# cold drawing seamless pipe by the surface in described, described vibration isolation rubber body 22 is as the rubber body of main vibration isolation, designed spacing under X, Y, the Z three-dimensional limited conditions; Because of the uneven exciting force that produces of balance motor rotor quality, X is bigger to rigidity Design.
Suspending shock-absorbing device is not only simple in structure behind the above-mentioned motor in electric automobile, is convenient to manufacture, and is convenient to assembling, and anti-vibration performance is superior, the endurance quality height.
