And, generally be flexible dish, flywheel and some bolts directly link between engine and the gearbox among the prior art, but the flexible dish is formed by several thin circular flexible steel sheet superpositions, generally do not exceed 10cm, can't satisfy the adjustment of relative distance between engine and the gearbox, pass through the bolt directly to link by engine flywheel shell and gearbox flywheel shell outside the flexible dish, because the condition that engine flywheel shell and gearbox flywheel shell standard are not unified, can produce the phenomenon that can't match, also do not be favorable to being connected between engine flywheel shell and the gearbox.
SUMMERY OF THE UTILITY MODEL
The utility model provides an engine and automatic gearbox connecting device can satisfy and realize directly linking of engine and automatic gearbox under the condition of the effective output of power to thereby can adjust the length of shaft coupling as required and adjust the directly linking distance of engine and automatic gearbox, through the distance between adjustment engine and the gearbox, can provide effective space for the installation of engine water tank, in order to avoid appearing the interference problem of driver's cabin and water tank.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a connecting device for an engine and an automatic gearbox comprises a flywheel shell, a coupling, a crankshaft connecting flange and a gearbox connecting flange; the flywheel housing is fixed on the engine, and a crankshaft mounting hole of the flywheel housing is connected and mounted with a crankshaft of the engine; one end of the crankshaft connecting flange is fixedly connected with a crankshaft of the engine, and one end of the gearbox connecting flange is fixedly connected with an input shaft of the gearbox; and two ends of the coupler are fixedly connected with the other ends of the crankshaft connecting flange and the gearbox connecting flange respectively.
Preferably, a protective cover is arranged outside the connecting device, and two end faces of the protective cover are fixedly connected with the two flywheel housing mounting surfaces respectively.
Preferably, the protective cover comprises two arched tile-shaped protective cover monomers, two opposite sides of each arched tile-shaped protective cover monomer are turned outwards, the two protective cover monomers are spliced oppositely, and the corresponding turning parts are fixedly connected through bolts to form the cylindrical protective cover.
Preferably, the engine crankshaft, the crankshaft connecting flange, the coupling, the gearbox connecting flange and the protective cover are arranged on the same axis.
The beneficial effects of the utility model reside in that:
1. the linear connection of the engine and the gearbox is realized through the connection mode of the coupler, and the coupling has the advantages of simple connection mode, convenience in installation, low cost and short period.
2. The coupler is adopted to adjust the natural frequency of the engine, so that the torsional vibration amplitude of the engine can be reduced, the transmission device components are damped, buffered and protected, the centering performance is improved, the stability of output power is improved, and the service life of the power components is prolonged.
3. The installation space can be saved, the connection layout of the engine and the automatic gearbox is optimized, the water tank is directly installed below the cab, and the water tank is prevented from being installed on the chassis to occupy the installation space of the chassis.
