Abstract
The utility model relates to a disc type combined torsion spring, which is mainly characterized in that an inner disc body and an outer disc body are provided. At least two wavelike plate springs are radially arranged between the inner disc body and the outer disc body. As a result, the utility model is applicable for transferring the high power energy or absorbing the shock. Furthermore, the utility model has the advantages of simple and compact structure and good technological performance without worn parts, which can achieve the purposes of reliable running and durability.
Description
Technical field
The present invention relates to spring, is a kind of disc type combination torque spring.
Background technique
As everyone knows, motor car engine is subjected to the effect of firing pressure and reciprocal inertia force, can make bent axle produce cogging, thisly reverse change and pass to drive system, can make transmission gear knock and send annoying knock again, particularly diesel engine more very, this continual noise makes the very easy fatigue of driver, has syngignoscism.So in order to reduce the cogging amount, the double mass flywheel of making the absorbing element with spring is housed all generally, and, the absorbing element of double mass flywheel all made with helical spring.But because helical spring is subjected to the restriction of its diameter and wearing and tearing, so can only be used on the double mass flywheel of little torsion (500 Ns of rice are following) transmission.We know simultaneously, usually torque spring are made the engineering part of making transmitting torque in the prior art, sometimes also in order to make the absorbing parts.Can be used in torque spring on the motor car engine flywheel so? but torque spring of the prior art generally all is to form with single spring Coil-up, and its institute's energy energy delivered is little, shock attenuation result is little, is difficult to be applied to automobile with on the double mass flywheel.
Summary of the invention
The purpose of this invention is to provide a kind of disc type combination torque spring, make it effectively absorbing, can do high-power transmission to moment of torsion again.
The technical conceive of the present utility model of realizing above-mentioned purpose is to form one group with many torque springs, the characteristics of make it to bring into play the cluster spring deformation energy, transmitting energy.Concrete scheme of the present utility model is, has an inner disc and an outer dish, radially is equipped with at least two piece leaf springs that are wave-like type at this inner disc with between coiling outward.
Advantage of the present invention is that the vibration of institute's energy delivered or absorption is born jointly by many leaf springs, and the wave-like type leaf spring malformation energy of radial arrangement is big, therefore applicable to high-power energy transfer or absorbing.And the utility model is simple in structure, compact, and good manufacturability does not have any wear-out part, can reach purpose such as reliable, durable.
Description of drawings
Fig. 1 is a forward structure schematic representation of the present utility model.
Embodiment
Embodiment of the present utility model as shown in drawings.See that by Fig. 1 present embodiment has inside and outside two disk bodies 1,3, radially be connected with four leaf springs 2 that are wave-like type of uniform setting between outer disk body 1 and the inner tray 3.In another embodiment, evenly between disk body 1 and the inner tray 3 outside be provided with 12 wave-like type leaf springs.
According to various use occasions and requirement, the quantity of leaf spring 2 can be selected for use as required.
Claims (1)
1, a kind of disc type combination torque spring is characterized in that: have an inner disc and an outer dish, at this inner disc with radially be equipped with the leaf spring of wave-like type at least two outward between coiling.
