Abstract
The utility model relates to an arc double-shape spring with power carrying discs, and aims to provide the arc double-shape spring with the power carrying discs, wherein effective loads of the arc spring can be effectively improved, and technological requirements of dual mass flywheels of an existing automobile are met. The purpose is achieved through the following technical scheme, and the arc double-shape spring with the power carrying discs comprises an outer arc spring body and at least one inner arc spring body nested in the outer arc spring. Compared with the prior art, the arc double-shape spring is characterized in that the assembly of the arc double-shape spring with the power carrying discs is composed of the three arc spring bodies, so that the arc double-shape spring transmits larger torque compared with a common single spring; the sum of the radian of the two inner arc spring bodies is smaller than the radian of the outer arc spring body, so that the assembly of the arc double-shape spring with the power carrying discs meets the requirement for achieving second-level variable stiffness, more effectively transmits the large torque and plays a role in vibration attenuation better.
Description
Technical field
The utility model relates to a kind of Moving plate arc dimorphism spring of taking.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work, generally with spring steel, makes.Spring is an accumulator, and it has the function of stored energy, in order to control motion, the mitigation of parts, impacts or shakes, stores up the size of energy, measuring force etc., is widely used in machine, instrument.Spring, as a critical elements in industrial system, has very large use amount.
In existing automobile dual-mass flywheel, the major and minor flywheel that forms double mass flywheel is by being located at arc spring between them and carrying out transmitting torque and play the effect of torsion damping.This arc spring is all generally to use single spring, due to the spatial constraints of holding arc spring between itself material of single spring and the restriction of structure and the major and minor flywheel of double mass flywheel, the useful load amount of existing arc spring cannot meet the performance requirement of existing automobile dual-mass flywheel.
Summary of the invention
The purpose of this utility model is to provide a kind of useful load that can effectively improve arc spring, meet existing automobile dual-mass flywheel technical need take Moving plate arc dimorphism spring.
The purpose of this utility model is achieved through the following technical solutions: a kind of Moving plate arc dimorphism spring of taking, and it comprises an outer arcuate spring and at least one arc spring, described arc spring is nested in outer arcuate spring.
The radian of described arc spring is less than outer arcuate spring.
The quantity of described arc spring is two, and two arc springs are nested in respectively in the two ends of outer arcuate spring.
The radian sum of two described arc springs is less than the radian of outer arcuate spring.
The two ends of described outer arcuate spring are provided with one and take Moving plate, described in take on Moving plate and be provided with coil component spring pad, the diameter of this compression spring is greater than the spring ring inner diameter of described outer arcuate spring; The described Moving plate inner side surface of taking is provided with inner spring plug, the surface, outer ring of described inner spring plug and the spring ring inner peripheral surface interference fit of arc spring.
Describedly take on Moving plate position between compression spring and inner spring plug and be surrounded with the draw-in groove ditch concaving; Described inner spring is provided with lead angle away from one end of compression spring beyond the Great Wall.
Compared to prior art, the utility model has the advantage of:
Taking Moving plate arc dimorphism spring, is by taking Moving plate, two arc springs and an outer arcuate spring to be linked together, and is combined into arc spring parts.
1. because having three arc springs, this assembly of taking Moving plate arc dimorphism spring forms, so, than general single spring, can transmit larger moment of torsion.
2. the radian sum due to two arc springs is less than outer arcuate spring, so this assembly of taking Moving plate arc dimorphism spring can be realized the requirement of two-stage variable stiffness, the more effectively effect of transmitting large torque and vibration damping.
Accompanying drawing explanation
A kind of Moving plate arc dimorphism spring assembling figure that takes of Fig. 1 the utility model.
Fig. 2 is the structural representation of taking Moving plate in the utility model.
Label declaration: 1, outer arcuate spring; 2, arc spring; 3, take Moving plate; 4, compression spring; 5, inner spring plug; 6, draw-in groove ditch; 7, lead angle.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:
Be illustrated in figure 1 and take Moving plate arc dimorphism spring assembling figure, it comprises an outer arcuate spring 1 and at least one arc spring 2, and described arc spring 2 is nested in outer arcuate spring 1.
The radian of described arc spring 2 is less than outer arcuate spring 1.
The quantity of described arc spring is two, and two arc springs 2 are nested in respectively in the two ends of outer arcuate spring 1.
The radian sum of two described arc springs 2 is less than the radian of outer arcuate spring 1.
As shown in Figure 2, the two ends of described outer arcuate spring 1 are provided with one and take Moving plate 3, described taking is provided with coil component spring pad 4 on Moving plate 3, the diameter of this compression spring 4 is greater than the mid diameter (being the mean value of the inside and outside diameter of spring ring) of described outer arcuate spring 1 spring ring, and is less than the spring ring outer diameter of described outer arcuate spring 1; Described Moving plate 3 inner side surfaces of taking are provided with inner spring plug 5, the surface, outer ring of described inner spring plug 5 and the spring ring inner peripheral surface interference fit of arc spring 2.
Further, for make to take Moving plate 3 and arc spring 2 can in conjunction with more firm, described, take on Moving plate 3 position between compression spring 4 and inner spring plug 5 and be surrounded with the draw-in groove ditch 6 concaving; For just arc spring 2 circles, holding to insert and taking in Moving plate 3, the one end away from compression spring 4 on described inner spring plug 5 is provided with lead angle 7, (being that the bore of inner spring plug 5 is by gradually large within outer).
While installing and using, one end of an arc spring 2 is imported from taking inner spring plug 5 lead angles 7 of Moving plate 3, make the spring ring inner side of inner spring plug 5 produce interference fit with inner spring plug 5 outsides, simultaneously, take position between compression spring 4 on Moving plate 3 and inner spring plug 5 and be surrounded with the draw-in groove ditch 6 concaving, draw-in groove ditch 6 can be buckled in the termination of arc spring 2 to take on Moving plate 3, make to take between Moving plate 3 and arc spring 2 more firm in conjunction with obtaining, then by two with the two ends (and the radian sum of two arc springs 2 is less than outer arcuate spring 1) of taking arc spring 2 that the mutual interference of Moving plate 3 assembles and be nested in respectively outer arcuate spring 1.
Owing to taking the connection function of Moving plate 3, an outer arcuate spring 1 and two arc spring 2 perfect combination are assembled together, form one and take Moving plate arc dimorphism spring members.
