Problems solved by technology

[0004] The above-mentioned square dual-mass flywheel structure is equipped with magnetorheological fluid in the traditional dual-mass flywheel, which reduces the vibration transmission to a certain extent. However, after the spring is compressed, there will inevitably be a reaction force. In the interaction between the positive and reaction forces Under the circumstances, the above-mentioned dual-mass flywheel itself must have a resonant frequency, which is determined by the design structure of the dual-mass flywheel and cannot be eliminated, thus affecting the smooth effect of power transmission

Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] Such as figure 1 , figure 2 , Image 6 , Figure 7 As shown, the hydraulic dual-mass flywheel includes a main flywheel 1 and a secondary flywheel 2 that are coaxially arranged and can rotate relatively. The main flywheel 1 has an oil injection channel 11 whose inlet can communicate with the oil pump. The outlet of the oil injection channel 11 faces Auxiliary flywheel 2 has a diaphragm 21 extending radially on the auxiliary flywheel 2. When the main flywheel 1 rotates relative to the auxiliary flywheel 2, the oil gushed out from the outlet of the oil injection channel 11 can be sprayed on the side of the diaphragm 21. The main flywheel 1 is used to connect with the crankshaft and rotate synchronously. When the ma...

Abstract

The invention provides a hydraulic double-mass flywheel, which belongs to the technical field of automobiles. It solves the technical problem of poor smoothness of power transmission in the existing dual-mass flywheel structure. The hydraulic double-mass flywheel includes a main flywheel and an auxiliary flywheel that are arranged coaxially and can rotate relatively. The main flywheel has an oil injection channel whose inlet can communicate with the oil pump, and the outlet of the oil injection channel faces the auxiliary flywheel. Flywheel, the auxiliary flywheel has a radially extending baffle, when the main flywheel rotates relative to the auxiliary flywheel, the oil gushed out from the outlet of the oil injection channel can be sprayed on the side of the baffle and push the auxiliary flywheel to rotate . The hydraulic double-mass flywheel can realize soft connection in the true sense and improve transmission smoothness.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a hydraulic double-mass flywheel. Background technique [0002] The dual-mass flywheel divides the original flywheel into two parts, and one part remains on the side of the original engine to play the role of the original flywheel for starting and transmitting the rotational torque of the engine. This part is called the first mass (primary quality), and the other part is placed on the side of the transmission of the drive train to increase the moment of inertia of the transmission. This part is called the second mass (secondary mass). The first mass and the second mass are connected by a spring to achieve Isolates torsional and rolling vibrations from the engine crankshaft and transmission input shaft. [0003] An intelligent magneto-rheological fluid dual-mass flywheel with application publication number CN103758923A includes an outer rotor assembly, a magnetorheological fluid...
