Description
Technical field
The utility model relates to a kind of connection set, is specifically related to a kind of engine speed changer connection set.
Background technique
Along with the diversified development of commercial vehicle engine, a kind of novel motor can carry integral flywheel shell at rear side, and this flywheel casing can improve the matching of motor and flywheel casing, reduces assembling difficulty.But traditional speed changer protecgulum is wider, due to self structure, causing cannot the motor of matching strip integral flywheel shell.Therefore develop a kind of can firmly, the connection set of stably connecting engine and speed changer, thus play the motor advantage carrying integral flywheel shell to greatest extent, tool is of great significance.
Model utility content
The purpose of this utility model is for above-mentioned the problems of the prior art, there is provided a kind of structure simple engine speed changer connection set, large to motor and speed changer two power assembly can firmly be connected by this connection set effectively, thus completes the transmission of power.
To achieve these goals, the technical solution adopted in the utility model is: comprise the transition bracket for connecting speed changer and the connecting plate for connecting engine, described connecting plate offers the mounting hole matched with motor attachment hole, and connecting plate and transition bracket center also offer the positioning hole cooperatively interacted, the positioning hole edge of transition bracket is provided with positioning boss, positioning boss is inner locates with the bearing cap of motor, positioning boss is outside locates with integral flywheel shell, the space arranging return spring is left at positioning boss center, return spring one end connects the release bearing of speed changer, the other end is connected to bearing cap head, by connecting plate is connected with transition bracket, motor and speed changer is made to realize being connected.
Described connecting plate is connected by bolt with transition bracket.
Described bolt arrangement is on connecting plate and transition bracket multiple attachment holes that edge is offered in the outer part.
Described positioning boss arranged outside has stiffening rib.
Described stiffening rib is several stiffening ribs being arranged on surrounding outside positioning boss.
Described return spring one end connects the release bearing of speed changer, and the other end is connected to the fixing bolt head of bearing cap.
Compared with prior art, the utility model is by connecting plate and transition bracket connecting engine and speed changer respectively, by in conjunction with connecting plate and transition bracket, realize the connection of motor and speed changer, solve the motor that carries integral flywheel shell and the inconsistent problem of transmission interface, firmly, effectively large to motor and speed changer two power assembly can be connected, thus complete the transmission of power.The positioning hole edge of the utility model transition bracket is provided with positioning boss, realized the bearing cap of speed changer and the location of integral flywheel shell by positioning boss, the space arranging return spring is also left at positioning boss center, and therefore do not need increases separately the device connecting return spring on connecting plate.The utility model structure is simple, is connected firmly, easy accessibility.
Further, the outside surrounding of the utility model positioning boss is provided with several stiffening ribs, coordinate with positioning boss, simplify the structure of connecting plate, and the power making connecting plate bear is less, enhance intensity and the durability of transition bracket simultaneously, thus improve reliability and the working life of device entirety.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Along with the diversified development of commercial vehicle engine, rear side carries the motor of integral flywheel shell, and its interface shape as shown in Figure 1, has the twin countershaft transmission protecgulum interface size in jack shaft spindle nose hole 3 as shown in Figure 2.By finding out in figure that the protecgulum of case of transmission is wider, and the pitch-row of motor attachment hole 1 on integral flywheel shell 7 is less, and the two cannot mate.For solving this problem, needing to design a kind of connection set, firmly, effectively large to motor and speed changer two power assembly can be connected, thus complete the transmission of power.
See Fig. 3, 4, 5, the utility model comprises the transition bracket 8 for connecting speed changer and the connecting plate 9 for connecting engine, connecting plate 9 offers the mounting hole 10 matched with motor attachment hole 1, and connecting plate 9 and transition bracket 8 center also offer the positioning hole 2 cooperatively interacted, positioning hole 2 edge of transition bracket 8 is provided with positioning boss 4, positioning boss 4 is inner locates with the bearing cap 6 of motor, positioning boss 4 is outside locates with integral flywheel shell 7, the space arranging return spring is left at positioning boss 4 center, return spring one end connects the release bearing of speed changer, the other end is connected to the construction bolt head of bearing cap 6, outside positioning boss 4, surrounding is provided with several stiffening ribs 5.By being connected by bolt with transition bracket 8 by connecting plate 9, make motor and speed changer realize being connected, bolt arrangement is on connecting plate 9 with transition bracket 8 multiple attachment holes 11 that edge is offered in the outer part.The utility model is when assembling, first transition bracket 8 is arranged on speed changer front end, afterwards connecting plate 9 and transition bracket 8 are fixed together, connecting plate 9 is connected with integral flywheel shell 7 the most at last, and corresponding component are installed, thus complete the connection of motor and speed changer, complete the transmission of power.The utility model transition bracket 8 is provided with positioning boss 4 and stiffening rib 5, simplify the structure of connecting plate 9, and the power making connecting plate 9 bear is less, enhances intensity and the durability of transition bracket 8 self simultaneously, thus improve reliability and the working life of whole device.
