Abstract
The utility model relates to an engine flywheel of U-shaped connection structure, including the flywheel body, a flywheel body terminal surface is provided with the flange interface that is used for being connected with engine crankshaft rear end flange dish, be provided with ring gear installation face on the outer wall of flange interface, another terminal surface of flywheel body is provided with the echelonment clutch interface that is used for being connected with the clutch, clutch interface edge is provided with the annular flywheel tang of outside protrusion along flywheel body axis in addition, flywheel body middle part is provided with connection structure, connection structure uses flywheel body axis as the center and the cross section is the connection structure of U-shaped, when guaranteeing flywheel inertia, has alleviateed flywheel weight, has reduced the operation load of whole car; and accelerates heat dissipation together with the heat dissipation window.
Description
Technical field
The utility model relates to engine art, refers to a kind of engine flywheel of U-shaped linkage structure particularly.
Background technique
The effect of engine flywheel is stored engine power, overcomes the resistance of miscellaneous part, makes bent axle Rotating with Uniform; By being arranged on the clutch on flywheel, motor and vehicle transmission are coupled together; Engine flywheel is combined with starter motor, is convenient to engine start.Therefore engine flywheel has three distinguishing features: 1. have certain rotary inertia, to ensure the Rotating with Uniform of bent axle; 2. the requirement be connected with motor and vehicle transmission is met; 3. be combined with starter motor by gear ring, and rotary inertia can not be excessive, so that engine start.
As depicted in figs. 1 and 2, existing engine flywheel comprises flywheel body 1 in the form of annular discs, one end face 2 of flywheel body 1 is connected with engine crankshaft rear end flange plate, other end has a rubbing surface 3 in the form of a ring and for being combined with clutch, rubbing surface 3 outer rim has flywheel seam 4, flywheel seam 4 is that whole circle is cylindrical, flywheel body 1 has gear ring attachment face 5.Be unfavorable for that clutch dispels the heat after rubbing surface 3 is combined with clutch, the situation that particularly flywheel seam is darker.And be the smooth starting and the clutch heat radiation that ensure motor, flywheel end face 2 and rubbing surface 3 relatively far apart, can not limit the demand that motor is connected with multiple vehicle transmission.Clutch heat radiation is bad, will reduce the transmission efficiency of clutch control part, may cause being separated not thorough, cause the premature wear of friction plate, also can cause shift of transmission difficulty time serious.During for ensureing the intensity of flywheel and rotary inertia, flywheel can be too heavy, increases complete vehicle weight and cost.
Summary of the invention
The purpose of this utility model will overcome upper the deficiencies in the prior art exactly, provides a kind of and adapts to multiple vehicle transmission connection requirement, and the engine flywheel of the U-shaped linkage structure of dispelling the heat good.
To achieve these goals, the engine flywheel of the U-shaped linkage structure designed by the utility model, comprise flywheel body, described flywheel body one end face is provided with the flange-interface for being connected with engine crankshaft rear end flange plate, the outer wall of described flange-interface is provided with gear ring attachment face, described flywheel body other end is provided with the rubbing surface for being connected with clutch, described rubbing surface edge is provided with along the outwardly annular flywheel seam of flywheel body axis, it is characterized in that: in the middle part of described flywheel body, be provided with the linkage structure that cross section is U-shaped centered by flywheel body axis.
Further, described flywheel seam is provided with at least one thermal window, described thermal window opening is outside along flywheel body axis.
Further, described thermal window has 3, is evenly arranged on flywheel seam, convenient heat radiation.
The utility model has the advantage of: the linkage structure that cross section is U-shaped is set in flywheel body, can the wall thickness in solenoidoperated cluthes structural friction face by U-shaped linkage structure, together with thermal window, air circulation can be increased, accelerate the heat radiation of clutch under working state, a series of hidden danger that efficient solution causes except clutch heat dispersal situations difference, and improve the transmission efficiency of clutch control part, reduce the premature wear of friction plate.The linkage structure of U-shaped, while guarantee Rotary Inertia of Flywheel, alleviates flywheel weight, reduces the running load of car load.

Fig. 3 is a kind of engine flywheel arrangement schematic diagram of U-shaped linkage structure.
Fig. 4 is the B-B sectional view of Fig. 3.
In figure: flywheel body 1, flange-interface 2, rubbing surface 3, flywheel seam 4, gear ring attachment face 5, linkage structure 6, thermal window 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, Fig. 1 and Fig. 2 describes in detail in the introduction, just repeats no more here.
The engine flywheel of the U-shaped linkage structure shown in Fig. 3 and Fig. 4, comprise flywheel body 1, described flywheel body 1 one end face is provided with the flange-interface 2 for being connected with engine crankshaft rear end flange plate, the outer wall of flange-interface 2 is provided with gear ring attachment face 5, flywheel body 1 other end is provided with the rubbing surface 3 for being connected with clutch, rubbing surface 3 edge is provided with along the outwardly annular flywheel seam 4 of flywheel body 1 axis, flywheel seam 4 is provided with 3 openings along the outside thermal window 7 of flywheel body 1 axis; Be provided with linkage structure 6 in the middle part of flywheel body 1, described linkage structure 6 is centered by flywheel body 1 axis and the cross section linkage structure 6 that is U-shaped.
By the change width of U-shaped linkage structure 6, the distance between end face 2 and rubbing surface 3 can be changed, meet the requirement that flywheel is connected with motor and vehicle transmission.
The linkage structure 6 of U-shaped can control the wall thickness at rubbing surface 3 place, together with thermal window 7, air circulation can be increased, accelerate the heat radiation of clutch under working state, a series of hidden danger that efficient solution causes except clutch heat dispersal situations difference, and improve the transmission efficiency of clutch control part, reduce the premature wear of friction plate.Further, U-shaped linkage structure 6, while guarantee Rotary Inertia of Flywheel, alleviates flywheel weight, reduces the running load of car load.
