Abstract
The utility model provides a balance shaft and plate spring seat connecting structure. The balance shaft and plate spring seat connecting structure comprises a balance shaft, a gland and four bolts, wherein a fastening piece is sleeved on an inner shaft body at the shaft end of the balance shaft; four screw holes are formed in the fastening piece and are symmetrically distributed on the two sides of the central line of the fastening piece; four through holes are formed in the gland and correspond to the screw holes; and the bolts penetrate through the through holes and the screw holes to fix the gland onto the balance shaft. The structure is reasonable in design and is simple; the gland is combined with the shaft end of the balance shaft through the four bolts, so that the gland and the balance shaft are connected firmly; and the balance shaft and plate spring seat connecting structure is convenient to operate.
Description
[technical field]
The utility model relates to the automotive suspension technical field, the connection structure of particularly a kind of balance shaft and spring block.
[background technology]
Equalizing-suspension device mainly is made up of spring block, balance shaft support, adapter shaft, balance shaft etc. in the prior art.This equalizing-suspension device mainly is the purpose that can automatic compensation when guaranteeing that vehicle ' is on uneven road surface monolateral two trailing wheels can well contact with the road surface, and its principle is equivalent to a bascule.Being connected between balance shaft and the spring block is to carry out bonded assembly through a connection structure; As shown in Figure 1, the traditional balance shaft and the connection structure of spring block comprise: balance shaft 1 ', gland 2 ' and bolt 3 '; One section screw thread is arranged on the interior axis body of balance shaft axle head, gland cover 2 ' is contained on the balance shaft 1 ' axle head, gland is fixed on the balance shaft 1 ' through bolt 3 '.And then spring block is connected with balance shaft through gland 2 '.This bolt is generally with M80 suspension king bolt 3 '; Because especially big spanner is few on the market, therefore gland 2 ' is locked to balance shaft 1 ' the drilling trouble of making comparisons, and the combination of gland 2 ' and balance shaft 1 ' is firm inadequately with M80 suspension king bolt 3 '; And carry out stationary gland 2 ' through a king bolt and exist a drawback, when automobile during in the travels down of jolting, the power that balance shaft 1 ' produces is all born by 1 bolt 3 ', long and for a long time it, phenomenon of rupture can take place in bolt 3 ' easily.
[summary of the invention]
The technical matters that the utility model will solve is to provide the connection structure of a kind of balance shaft and spring block, makes the structure between gland and the balance shaft more firm.
The utility model is achieved in that the connection structure of a kind of balance shaft and spring block; Comprise balance shaft and gland; Also comprise four bolts; Be arranged with a fastener on the interior axis body of the axle head of said balance shaft, said fastener offers four screws, the both sides that are distributed in fastener centerline of said four screws symmetry; Offer four through holes on the said gland, the position of said through hole is corresponding with the position of said screw; Said through hole of said bolt-through and screw are fixed on said gland on the said balance shaft.
Further, the specification of the bolt of two diagonal line settings is M20 in four bolts on the said gland; The specification of the bolt of remaining two diagonal line settings is M24.
The advantage of the utility model is: the utility model is arranged with a fastener on the interior axis body of the axle head of balance shaft; Said fastener offers four screws; And on gland, offer four through holes, run through through hole respectively through four bolts then and screw is fixed on said gland on the said balance shaft; Spring block just can be connected with balance shaft through gland.The utility model is reasonable in design, simple in structure, combines through the axle head of four bolts with gland and balance shaft, and is more firm between gland and the balance shaft, and easy to operate, improved the stability of car load.
[description of drawings]
Fig. 1 is the structural representation of the connection structure of balance shaft and spring block in the prior art.
Fig. 2 is the structural representation of first embodiment of the utility model.
Fig. 3 is the exploded drawings of first embodiment of the utility model.
Fig. 4 is the structural representation of second embodiment of the utility model.
[specific embodiment]
See also Fig. 2 and shown in Figure 3; A kind of balance shaft of first embodiment of the utility model and the connection structure of spring block; Comprise balance shaft 1 and gland 2, also comprise four bolts 3, be arranged with a fastener 4 on the interior axis body of the axle head of said balance shaft 1; Said fastener 4 offers four screws 41, the both sides that are distributed in fastener 4 line of centerss of said four screws, 41 symmetries; Offer four through holes 21 on the said gland 2, the position of said through hole 21 is corresponding with the position of said screw 41; Said bolt 3 runs through said through hole 21 and with screw 41 said gland 2 is fixed on the said balance shaft 1.Fix through four bolts 3 like this, make between gland 2 and the balance shaft 1 more firm; Spring block (not shown) just can be connected with balance shaft 1 through gland 2.Wherein fastener 4 can be circular block, and this fastener 4 is integrated with balance shaft or fastener 4 is on the interior axis body of the spot welding axle head that is connected balance shaft 1.
As shown in Figure 4, be the utility model second embodiment, the difference of itself and first embodiment is, is four different bolts in four bolts on the said gland 2, the specification of the bolt 5 of wherein two diagonal line settings is M20; The specification of the bolt 6 of remaining two diagonal line settings is M24.Because the appearance diversified in specifications of bolt, so the screw on the fastener, the through hole on the gland will change accordingly.The design-calculated purpose is like this: when automobile during in the travels down of jolting, the power that balance shaft 1 produces can be evenly distributed on four bolts, and bolt is not easy to rupture like this.
In a word, the utility model is reasonable in design, simple in structure, combines through the axle head of four bolts with gland and balance shaft, and is more firm between gland and the balance shaft, and easy to operate, improved the stability of car load.
Though more than described the specific embodiment of the utility model; But the technical personnel of being familiar with the present technique field is to be understood that; We described concrete embodiment is illustrative; Rather than being used for qualification to the scope of the utility model, those of ordinary skill in the art are in the modification and the variation of the equivalence of doing according to the spirit of the utility model, all should be encompassed in the scope that the claim of the utility model protects.
