The invention aims to provide a dual-mass flywheel, which solves the problem that the conventional dual-mass flywheel can ensure the normal work of the dual-mass flywheel under the extreme overload working condition and the overlong service condition.
In order to achieve the above object, the present invention provides a dual mass flywheel with overload protection function, comprising a first mass and a second mass coaxially arranged; the first mass comprises a flywheel and a gear ring, and the right end face of the flywheel is provided with an axial boss; the second mass comprises a mandrel and a flange, and a radial boss is arranged on the outer surface of the mandrel; the axial bosses of the flywheel and the radial bosses of the mandrel are arranged in a staggered manner and have a certain angle space; the first mass and the second mass transmit torque through an elastic unit, the elastic unit comprises a first scroll spring, a second scroll spring, an inner side pad, an outer side pad and an elastic piece, the first scroll spring and the second scroll spring are coaxially arranged with the first mass and the second mass, the first ends of the first scroll spring and the second scroll spring are combined with the second mass, and the second ends of the first scroll spring and the second scroll spring are combined with the first mass; the inner pad and the outer pad radially limit the first and second volute springs; the elastic member is disposed between the laps of the first and second spiral springs.
The present invention will be described in detail below with reference to the drawings and embodiments, and typical examples and illustrations will be given for the sake of understanding in the course of the description, but are not intended to be the only way in which the present invention may be practiced.
FIG. 1 is a view of a dual mass flywheel according to a first preferred embodiment of the present invention. As shown in fig. 1, the dual mass flywheel includes a first mass (including the flywheel 01, the ring gear 15, the inner race of the large bearing 04, and the outer race of the small bearing 14) and a second mass (including the spindle 02, the screw 11, the inner pin 12, the outer pin 13, and the outer race of the large bearing 04). The first mass is coaxially connected to a crankshaft of the engine, and for the sake of simplicity of explanation, an axis of the crankshaft of the engine will be referred to as an axis of the dual mass flywheel, in view of the fact that several components of the present invention are coaxially connected. First quality and second quality are connected through first spiral spring 05 between, and the one end and the first quality of first spiral spring 05 combine, and the other end and the second quality combine, absorb vibration through elastic deformation. In this embodiment, the inventor has already described the chinese patent No. 202110015123.2, and the present invention is not repeated.
In a preferred version, as shown in fig. 1, the flywheel 01 includes at least one axial boss 101 and the spindle 02 includes at least one radial boss 201. The axial bosses 101 of the flywheel 01 and the radial bosses 201 of the mandrel 02 are arranged in a staggered manner, and have a certain angle space alpha. Therefore, under the extreme overload working condition and the overlong service condition, even under the condition that the volute spiral spring fails, the dual-mass flywheel can normally transmit torque, and the reliability of the dual-mass flywheel is ensured.
Fig. 2 is an overall view of a dual mass flywheel in accordance with a preferred embodiment of the present invention.
FIG. 3 is an exploded view and a schematic torque transmission path of a dual mass flywheel in accordance with a preferred embodiment of the present invention. Embodiments of the present invention will be described in detail below with reference to fig. 1, 2, and 3. As shown in fig. 3, when the engine is started, the gear ring 15 transmits torque to the flywheel 01, then the flywheel groove 102 transmits the torque to the inner hanging leg 502 of the spring, and then to the outer hanging leg 501, the outer hanging leg 502 transmits to the mandrel groove 202, and the mandrel 02 transmits the torque to the end cover 03.
Under the overload working condition, when the deformation angle of the first spiral spring 05 reaches alpha, the axial boss 101 of the flywheel 01 is contacted with the radial boss 201 of the mandrel 02 to form a new torque transmission path, so that the transmission torque passing through the first spiral spring 05 is not increased, and the effect of protecting the first spiral spring 05 is achieved.
In fig. 3, in addition to a first elastic system consisting of a first spiral spring 05, a first elastic pad 06, a first gasket 07, a first inner pad 08 and a first outer pad 09, there is a set of second elastic system connected in parallel with the first elastic system, consisting of a second spiral spring 05a, a second elastic pad 06a, a second gasket 07a, a second inner pad 08a and a second outer pad 09 a. The first elastic system and the second elastic system work in parallel, and the reliability of the dual-mass flywheel is improved. The first spiral spring 05 and the second spiral spring 05a are wound in the same direction or in opposite directions, so that the performance balance of the dual-mass flywheel during loading and unloading is improved.
FIG. 4 is a view of the flywheel of the preferred embodiment of the present invention, wherein the recess 102 is engaged with the inner leg 502 of the first spiral spring 05.
Fig. 5 is a view of the mandrel of the preferred embodiment of the present invention, with the groove 202 mating with the inner leg 501 of the first spiral spring 05.
Fig. 6 is a graph of stiffness and overload protection position for a dual mass flywheel in accordance with a preferred embodiment of the present invention. The stiffness graph is a variable stiffness curve, and the greater the torque, the greater the stiffness. When the load is lower, the rigidity is small, the deformation is large, and the wave energy can be absorbed; when the load is higher, the rigidity is large, the deformation is small, and the high-frequency buffer vibration absorber is suitable for high-frequency buffer vibration attenuation. It follows that the dual mass flywheel is particularly suitable for high power vehicles. Under the overload working condition, when the deformation angle of the spring 05 reaches alpha, the axial boss 101 of the flywheel 01 is contacted with the radial boss of the mandrel 02 to form a torque transmission path connected with the spring in parallel, so that the effect of protecting the spring is achieved, and the reliability of the dual-mass flywheel is improved.
The above description is only for the purpose of describing the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any variations and modifications made by those skilled in the art based on the above disclosure are within the scope of the appended claims.
