Description
Technical field
The utility model relates to vehicle technology field, be specifically related to a kind of shock absorbing device for electric vehicle.
Background technique
Green Product electric motor car popular in the market, because of its clean environment firendly, to consume the energy few, convenient and swift and enjoy the favor of consumers in general.But due to the irrationality existing for electric vehicle structure design, the performance of electric motor car itself also also exists many defects, and the design as vibration insulating system is exactly one of them.Traditional method is transplanted in electric motor car by the spring damper of motorcycle, its reason is in Structure and Properties, there is many similarities because of both on the one hand, be then because its cost of production is low, structure simple, be easy to production on the other hand, and become the first-selection of vast electric motor car manufacturer.Along with people propose further requirement to travelling comfort, the effectiveness in vibration suppression of this spring damper can not meet people to travelling comfort proposed requirement.Therefore, existing spring damper is replaced in the urgent need to a kind of novel vibration damper.
Model utility content
For the deficiency that prior art exists, the utility model object is to provide a kind of shock absorbing device for electric vehicle, and structure is simple, good damping effect, and long service life is practical.
To achieve these goals, the utility model realizes by the following technical solutions: shock absorbing device for electric vehicle, comprise the first fulcrum, the second fulcrum, the first cylinder, the second cylinder, connecting rod and spring housing, first fulcrum, the second fulcrum respectively with the first cylinder, the second cylinder, the piston rod of the first cylinder, the second cylinder is connected by connecting rod, and connecting rod and piston rod outer cover are connected to spring housing.
As preferably, the first described fulcrum and the second fulcrum are circle.
As preferably, described spring housing two ends respectively with the first cylinder, the second cylinder contact.
As preferably, described spring housing outer cover is connected to rigid sheath.The extended length of described spring housing is less than the length of rigid sheath.
The beneficial effects of the utility model: structure is simple, good damping effect, long service life is practical.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: shock absorbing device for electric vehicle, comprise the first fulcrum 1, second fulcrum 2, first cylinder 3, second cylinder 4, connecting rod 5 and spring housing 6, first fulcrum 1, second fulcrum 2 respectively with the first cylinder 3, second cylinder 4, the piston rod of the first cylinder 3, second cylinder 4 is connected by connecting rod 5, and connecting rod 5 and piston rod outer cover are connected to spring housing 6.
It should be noted that the first described fulcrum 1 and the second fulcrum 2 are circle.
It should be noted that described spring housing 6 two ends contact with the first cylinder 3, second cylinder 4 respectively.
In addition, described spring housing 6 outer cover is connected to rigid sheath 7, and dust etc. can be avoided to enter cylinder and spring inner, and impact is damping effect.The extended length of described spring housing 6 is less than the length of rigid sheath 7.
This embodiment realizes damping effect by two cylinders and spring housing, and multiple damping device achieves multiple damping effect, uses safety and comfort more.
This embodiment structure is simple, good damping effect, and long service life is practical.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
