Problems solved by technology
When a vehicle using a dual-mass flywheel is ignited and started or the vehicle is short-started, the engine speed will pass through the dual-mass flywheel resonance point, causing dual-mass flywheel resonance, which affects the comfort of the vehicle's NVH and the service life of the dual-mass flywheel. There are improvements space

Embodiment Construction
[0030] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0031] The following will refer to the attached Figure 1-Figure 9 The flywheel assembly 100 for vehicles of the present invention will be described in detail in conjunction with the embodiments. The vehicle can be provided with an engine and a transmission, and a clutch is provided between the engine and the transmission, that is, the clutch is used to engage or separate the engine and the transmission, and when the engine and the transmission are engaged through the clutch, the power output by the engine can be transmitted to the transmission.
[0032] Such as Figure 1-Figure 9 As shown, a flywheel assembly 100 for a vehicle according to an embodiment of the present invention includes a primary flywheel 1 , a secondary flywheel 2 and a switching device 3 .
[0033] The primary flywheel 1 is adapted to b...

The invention discloses a flywheel assembly for a vehicle, an engine with the flywheel assembly and a vehicle with the flywheel assembly. The flywheel assembly for the vehicle comprises a primary flywheel, a secondary flywheel and a switching device, wherein the primary flywheel is suitable to be fixed on an engine crankshaft of the vehicle; the secondary flywheel and the primary flywheel are connected through an elastic element to be suitable for being connected with a gear box of the vehicle through a clutch; the switching device is set in a manner that the primary flywheel and the secondary flywheel can be selectively synchronized so as to enable the primary flywheel and the secondary flywheel to synchronously rotate. According to the flywheel assembly for the vehicle, which is provided by the embodiment of the invention, when the engine is started, the primary flywheel and the secondary flywheel are synchronized through the switching device, so that the resonance of the primary flywheel and the secondary flywheel can be avoided.
Description
technical field [0001] The present invention relates to the technical field of vehicles, in particular to a flywheel assembly for a vehicle, an engine with the flywheel assembly and a vehicle with the engine or the flywheel assembly. Background technique [0002] In the related technology, during the ignition process of the engine, the engine speed gradually increases from zero to the idle speed (generally above 750 rpm), and the dual-mass flywheel including the primary flywheel and the secondary flywheel attenuates the engine speed through the elastic element between the two-stage flywheels. The torque fluctuates, and the resonance range of the dual-mass flywheel is lower than the engine idle speed in the vehicle state. When a vehicle using a dual-mass flywheel is ignited and started or the vehicle is short-started, the engine speed will pass through the dual-mass flywheel resonance point, causing dual-mass flywheel resonance, which affects the comfort of the vehicle's NVH ...
