Abstract
The utility model relates to an arc-shaped spring of a double-mass flywheel. The arc-shaped spring of a double-mass flywheel is characterized in that the outer side space between the every two adjacent sections of the spring is larger than the inner side space, so that the spring is arc-shaped under natural condition; and the shape of the spring under natural condition is matched with that of an arc-shaped slot arranged between the inner walls of the primary flywheel and the secondary flywheel of the double-mass flywheel. The arc-shaped spring provided by the utility model solves the problem that the common spring has high torque rigidity and poor vibration damping effect when being used as a torque damper of the double-mass flywheel to transmit torque, and effectively improves the vibration damping performance of the double-mass flywheel.
Description
Technical field
The utility model relates to a kind of spring, especially a kind of double mass flywheel arc spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to come work, generally makes with spring steel.Spring is an individual accumulator, and it has the function of stored energy, impacts or shakes, stores up the size of energy, measuring force etc. in order to motion, the mitigation of control parts, is widely used in machine, the instrument.Spring has very big use amount as a critical elements in the industrial system, but because existing spring all is straight spring basically, under the situation in some circular arcs or arcuate structure space, this common spring can't satisfy this type of and use needs.
Particularly in the automobile double mass flywheel, the major and minor flywheel that constitutes double mass flywheel is by being located at spring between them and coming transmitting torque and play the effect of torsion damping, adopt common straight spring, because torsional stiffness is big, the possibility that produces torsional resonance is big, influences the comfort level and the transmission efficiency of vehicle drive system.
Summary of the invention
The purpose of this utility model is to provide a kind of double mass flywheel arc spring, it has solved common spring as the torsional vibration damper transmitting torque of double mass flywheel the time, existing torsional stiffness is big, the problem of effectiveness in vibration suppression difference, effectively raises the damping performance of double mass flywheel.
The purpose of this utility model is to be achieved by the following scheme: a kind of double mass flywheel arc spring, it is characterized in that: thus the outside spacing between adjacent two joints of described spring all makes spring curved under nature greater than inboard spacing, and the shape of described spring under nature is identical with the curve bath of being located between the major and minor flywheel inwall of double mass flywheel.
Compared to prior art, the utlity model has following advantage: it has solved common spring as the torsional vibration damper transmitting torque of double mass flywheel the time, existing torsional stiffness is big, the problem of effectiveness in vibration suppression difference, effectively raise the damping performance of double mass flywheel, help improving the comfort level and the transmission efficiency of vehicle drive system.
Description of drawings
Fig. 1 is the organigram of the double mass flywheel arc spring that provides of the utility model.
Fig. 2 is the double mass flywheel arc spring of Fig. 1 and the schematic representation that cooperates of double mass flywheel.
Number in the figure explanation: 1-spring, 2-double mass flywheel, 3-curve bath.
Embodiment
Below in conjunction with specification drawings and specific embodiments the utility model content is elaborated:
Be illustrated in figure 1 as a kind of double mass flywheel arc spring that the utility model provides, it is characterized in that: thus the outside spacing between adjacent two joints of described spring 1 all makes spring 1 curved under nature greater than inboard spacing, and described spring 1 under nature shape and the curve bath of being located between the major and minor flywheel inwall of double mass flywheel 23 coincide, as shown in Figure 2.
Claims (1)
1. double mass flywheel arc spring, it is characterized in that: described spring (1) thus adjacent two joints between outside spacing all make spring (1) curved under nature greater than inboard spacing, and the shape of described spring (1) under nature is identical with the curve bath of being located between the major and minor flywheel inwall of double mass flywheel (2) (3).
