Description
Technical field
The utility model relates to automobile technical field of vibration absorption, particularly relates to a kind of transmission shaft bump leveller.
Background technique
The performance requirement of current people to automobile each side is more and more higher, is especially embodied on vibration, noise.Along with the development of automotive engineering, bump leveller is the mode of a good vibration damping, noise reduction.The parts current automobile adding bump leveller get more and more, disclosed in Chinese patent, Authorization Notice No. is the vehicle door power vibration absorber of CN 201757151 U, this bump leveller is arranged on vehicle door interior trim panel, has good effectiveness in vibration suppression, greatly eliminates the noise in car.Disclosed in Chinese patent, Authorization Notice No. is a kind of steering system dynamic vibration absorber and the design method thereof of CN 101699098 B, and the problem of steering wheel vibration during to solve idling, improves the travelling comfort of vehicle.
Transmission shaft bump leveller conventional is at present external, is assemblied in outside transmission shaft, bump leveller is made two semicircles, passes through locked clip device.Disclosed in Chinese patent, Authorization Notice No. is the novel automobile transmission shaft torsional oscillation bump leveller device of CN 202360674 U, adopt said method to be arranged on transmission shaft by bump leveller device, this bump leveller complex structure, cost is higher, high to spatial requirement, poor reliability.
Model utility content
The technical problem that basic background technique exists, the utility model proposes a kind of transmission shaft bump leveller, and structure is simple, and cost of production is low, has and does not take installing space, the advantage that shock attenuation result is good.
A kind of transmission shaft bump leveller that the utility model proposes, the central siphon being arranged on transmission shaft is inner, comprise quality post, rubber body, outer tube and rubber layer, it is outside that outer coaxial tube is set in quality post, rubber body sulfuration forms entirety between quality post and outer tube, the vibration that rubber body is transmitted to quality post for weakening outer tube, and rubber layer is coated on outer tube periphery, axially evenly offer multiple groove at rubber layer outer surface along it, rubber layer can press-fit with the central siphon interference of transmission shaft.
Preferably, the axial length of outer tube is less than the axial length of quality post, and outer coaxial tube is enclosed within the middle part of quality post, and rubber body sulfuration is in the middle part of outer tube and quality post.
Preferably, outer coaxial tube is enclosed within the neutral position of quality post, and rubber body sulfuration is in the neutral position of outer tube and quality post.
Preferably, the cross section of groove is arc or V-arrangement.
Preferably, quality post adopts round steel to make.
Preferably, outer tube adopts 20 steel pipes to make.
Preferably, rubber body, rubber layer all adopt in high-cis butadiene rubber, natural rubber, fluosilicic rubber one or more make.
A kind of transmission shaft bump leveller that the utility model provides, comprise quality post, rubber body, outer tube and rubber layer, it is outside that outer coaxial tube is set in quality post, and rubber body sulfuration forms entirety between quality post and outer tube, the vibration that rubber body is transmitted to quality post for absorbing outer tube; Rubber layer is coated on outer tube periphery, and axially evenly offer multiple groove at rubber layer outer surface along it, rubber layer can press-fit with the central siphon interference of transmission shaft; Press-fiting in process, move to groove during rubber layer generation deformation, thus make bump leveller can assembling fastening with transmission shaft, when transmission shaft High Rotation Speed, still effectively ensure that bump leveller, with between transmission shaft, relative displacement does not occur, also ensure that transmission shaft not easily deforms simultaneously.Structure of the present utility model is simple, and cost of production is low, has and does not take installing space, the advantage that shock attenuation result is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of transmission shaft bump leveller that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of transmission shaft bump leveller that the utility model proposes.
With reference to Fig. 1, a kind of transmission shaft bump leveller that the utility model proposes, the central siphon being arranged on transmission shaft is inner, comprise quality post 1, rubber body 2, outer tube 3 and rubber layer 4, outer tube 3 coaxial sleeve is located in the middle part of quality post 1, rubber body 3 sulfuration forms entirety between quality post 1 and outer tube 3, the vibration that rubber body 2 is transmitted to quality post 1 for absorbing outer tube 3, rubber layer 4 is coated on outer tube 3 periphery, axially multiple groove 40 is evenly offered along it at rubber layer 4 outer surface, the cross section of groove 40 is V-arrangement, and rubber layer 4 can press-fit with the central siphon interference of transmission shaft.When rubber layer 4 press-fits with the central siphon interference of transmission shaft, there is deformation and move to groove 40 in rubber layer 4, thus make bump leveller can assembling fastening with transmission shaft, like this when transmission shaft High Rotation Speed, still effectively ensure that bump leveller, with between transmission shaft, relative displacement does not occur, also ensure that transmission shaft not easily deforms simultaneously.
In the utility model, quality post 1 adopts round steel to make, outer tube 3 adopts 20 steel pipes to make, rubber body 2, rubber layer 4 all adopt in high-cis butadiene rubber, natural rubber, fluosilicic rubber one or more make, make the shock attenuation result of rubber body 2, rubber layer 4 excellent.
In a particular embodiment, the axial length of outer tube 3 is less than the axial length of quality post 1, and outer tube 3 coaxial sleeve is in the neutral position of quality post 1, and rubber body 2 sulfuration in the neutral position of outer tube 3 with quality post 1, thus reaches stress equalization at axial direction.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
