Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Multifunctional gear room cover plate of the present utility model changes vibration frequency by at the gear chamber cover plate gradual change dome being set, to play the effect of noise reduction; In addition, also be provided with Idle wheel tower, idle pulley installation tower are installed, when satisfying the installation requirement of front end wheel train Idle wheel, idle pulley, simplify the structure, play equally the effect of noise reduction; Also have, also be provided with fuel injection pump gear on this gear chamber cover plate and observe the adjusting window, conveniently detachable fuel injection pump gear can be regulated fuel injection pump gear by window simultaneously the effect of regulating the engine oil advance angle that reaches is installed.
As shown in Figures 1 to 4, this multifunctional gear room cover plate concrete structure comprises: gear chamber cover plate body 1, and with gradual change dome 11, the Idle wheel of this gear chamber cover plate body 1 integrally casting moulding tower 12, idle pulley installation tower 13 and fuel injection pump gear are installed and are observed adjustment window 14.
