Before the utility model proposes, Patent Office of the People's Republic of China discloses a kind of name and has been called the change speed gear box auxiliary suspension, the patent No. is the utility model patent of ZL 200420074196.0, this patent adopts the Z-shaped stabilizer rod of torsion bar type, the stabilizer rod two ends are with the cylindricality rubber mount, be fixed on the vehicle frame by cushion bracket and support cushion block, interlude also is with the cylindricality rubber pad, is fixed on the change speed gear box by cover plate up and down.This structure is mainly come load-bearing, vibration damping by Z-shaped stabilizer rod, but Z-shaped stabilizer rod structure is more single, cause change speed gear box auxiliary suspension system stiffness wayward, and this structure is only controlled the displacement of change speed gear box above-below direction, to not spacing all around, make to be difficult for behind the change speed gear box position change checking, influence the stability of back transmission shaft system.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, a kind of change speed gear box auxiliary suspension device of automobile to be provided, make it can effectively control the multi-aspect rigidity of change speed gear box auxiliary suspension system, improving the spacing state of change speed gear box.
For achieving the above object, the utility model adopts following technical scheme: automobile gearbox auxiliary suspension device, comprise stable beam, the middle part of stablizing beam is connected with gear box casing with the change speed gear box cushion block with bolt, the two ends of stablizing beam connect to ground with bolt and auxiliary suspension cushion assembly, it is characterized in that described stable beam is straight beam or the bow beam that shaped steel constitutes.
Described auxiliary suspension cushion assembly is made of a pair of rubber mount, and each rubber mount central authorities has axial hole, and upper/lower terminal links to each other with steel plate respectively, is provided with the rubber mount locating bush that is connected with it at the upper end surface of steel plate; Two rubber mount symmetries are installed in the upper and lower surface of support mounting hole, the upper steel plate locating bush inserts in the support mounting hole, in above-mentioned two rubber mount in-to-in axial holees, place a swivel nut, this swivel nut length is less than two rubber mount thickness sums, bolt passes mounting hole, two the rubber mount locating bushs of stablizing the beam two ends and is positioned at rubber mount in-to-in swivel nut, is equipped with tight with double nuts in another rubber mount outer end.
Described rubber mount upper/lower terminal is one with the sulfuration of upper and lower end steel plate respectively.
The circular locating bush of described rubber mount upper steel plate band, circular locating bush and upper steel plate are same part.
The preferred taper hole of axial hole in the described rubber mount, the big end of taper hole are positioned at band locating bush steel plate one end, and small end is positioned at the other end.
Test shows that the utility model performance than background technology in improvement aspect control change speed gear box auxiliary suspension system stiffness, vibration isolation and the displacement of restriction change speed gear box obviously, make automobile power assembly and transmission shaft system be in good working order, the car load shake is controlled preferably.
The utlity model has following effect:
1, rubber mount is by changing elastomeric material prescription or inner structure, and the variable range of itself free state rigidity is wide, and control easily;
2, in fitting process, change the rubber mount amount of compression, can revise the rigidity of rubber mount mode of operation by Adjusting bolt Adjusting screw length;
3, can effectively control the vibration of dynamic assembly above-below direction, the evidence effectiveness in vibration suppression is obvious;
4, this automobile gearbox auxiliary suspension apparatus structure is simple, easy to assembly, and cost of parts is cheap;
5, a rubber mount pressurized, tension not, in use reliability and stability are good.
