Embodiment
Below with reference to drawings and Examples, the technological scheme of a kind of belt transmission wheel series of engine that the utility model relates to is described in further detail.
Refer to shown in Fig. 1, the mode of execution that the utility model relates to provides a kind of belt transmission wheel series of engine of new structure, and it comprises crank pulley 1, air condition compressor belt pulley 2, mechanical tensioning wheel 3, MGU motor pulley 4, hydraulic tensioning wheel 5, water pump pulley 6, first belt 7 and the second belt 8.Wherein mechanical tensioning wheel 3 is arranged between air condition compressor belt pulley 2 and MGU motor pulley 4.Hydraulic tensioning wheel 5 is arranged between crank pulley 1 and MGU motor pulley 4.
Further, crank pulley 1, air condition compressor belt pulley 2, mechanical tensioning wheel 3, MGU motor pulley 4, hydraulic tensioning wheel 5, driven by the first belt 7, and form the first plane.And water pump pulley 6 and crank pulley 1 are driven by the second belt 8, and form the second plane.And the first plane and the second plane are parallel to each other.
Further, during the assembling of each parts, the lower end immovable point of air condition compressor is directly installed on oil sump, its upper end immovable point by support installing on engine cylinder-body.Mechanical tensioning wheel lower end immovable point is arranged on air condition compressor; Its upper end immovable point is arranged on described MGU motor.And MGU motor lower end immovable point by support installing on cylinder body; Its upper end immovable point is directly installed on engine cylinder and covers.Hydraulic tensioning wheel is then arranged on engine cylinder-body.
Further, in different embodiments, wherein the second belt can be elastic belt.
Further, in different embodiments, wherein crank pulley can be the outer 6 groove structures of interior 3 grooves.
The working principle of the belt transmission wheel series of engine technological scheme that the utility model relates to is described as follows.
1, under MGU electric power generation pattern: due to MGU motor comparatively large rotating inertia, and small displacement engine height torsional oscillation, the belt of MGU motor both sides, side is slack list, side is pilled-in selvedge, and tension force has fluctuation by a relatively large margin, in order to ensure that train does not resonate, and air condition compressor and MGU motor non-slip, an Idle wheel must be placed in slack list to compensate slack list tension variation.
