Abstract

The utility model relates to a steel balance block, which is applied to wheel rims. The steel balance block comprises a locking hook and a block body, wherein a clamping space where edges of a vehicle wheel rim can be embedded is formed between the block body and the locking hook. The utility model is characterized in that a rivet projects from the block body and the locking hook is riveted to the block body via the rivet.

Description

The steel balance block

Technical field

The utility model relates to a kind of steel balance block that is arranged on wheel or its analogue.

Background technology

Because non-uniform mass or asymmetric, wheel vibration can occur when rotating, and then the part that respectively is provided with of vehicle caused damage, occur for fear of such situation, people are after having made wheel, can one or more balance blocks be set on wheel, so that wheel has the rotary balance performance.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of steel balance block comprises grab 10 and block 12, on block 12, be formed with two rivets 120, block 12 is by this two rivet 120 and grab 10 riveted joints, grab 10 hooks the circumferential flange of wheel rim 14 (with reference to Fig. 7, Fig. 7 has only shown the structure of part wheel, pneumatic tyre 13 is provided with around wheel rim 14), thereby the steel balance block is set on the wheel, block 12, with the face of grab 10 riveted joint near wheel rim 14, this steel balance block has such shortcoming:

1. just grab 10 is fitted with wheel rim 14, and grab 10 is relative less with the contact surface of wheel rim 14 chuckings, and the reliability of installation is not high;

2. block 12 just leans on riveted and fixed to grab 10, and centnifugal force that produces in the vehicle operating and impulsive force etc. might cause riveted joint to lose efficacy;

3 grabs 10 complex-shaped is unfavorable for automatic production.

Fig. 9, Figure 10 show a kind of steel balance block that U.S. Pat 20050062331 discloses, and different with aforementioned steel balance block is: block 22, with the face of grab 20 riveted joints away from wheel rim, i.e. grab upper at block.The grab of this steel balance block is easy to make, but this steel balance block has such shortcoming: as shown in figure 11, the steel balance block is installed the back or is occurred the incomplete situation of fitting of wheel rim of grab 22 and wheel rim 24 easily, have gap d 1 and d2 between the wheel rim of grab 22 and wheel rim 24, d1＜d2 in Figure 11; Perhaps block 22 and the wheel rim situation of not exclusively fitting, as shown in figure 12, block 22 has gap d 3, d4 with wheel rim, in Figure 12, d3＞d4; In addition, the auxiliary hole that forms rivet is difficult to processing on cambered surface.

The utility model content

The purpose of this utility model is to provide a kind of steel balance block that is used for wheel, and this steel balance block is arranged on the wheel rim of wheel rim of wheel, and it is easy to make and is firm with being provided with of wheel rim.

In order to realize described purpose, steel balance block of the present utility model, be arranged on the rim of wheel, it comprises grab and block, formation one can embed the grasping part at the edge of wheel rim between block and the grab, be characterized in: block protrudes a rivet, and grab is only by this rivet and block riveted joint.

Described steel balance block, its further characteristics are that this block is made by cold drawn section bar and the auxiliary hole of this rivet is formed on the plane of this block.

Described steel balance block, its further characteristics are that grab is upper block.

The beneficial effects of the utility model are: formation one can embed the grasping part at the edge of wheel rim between block and the grab, so just can not make grab form crooked back and forth complicated shape, grab is easy to make, and only rivet block and grab by a rivet, this has eliminated the uneven situation of assemblage gap that the balance block manufacturing errors causes, the people of this area adopt two rivets to rivet grab and block all the time, think the insufficient strength that is provided with of a rivet, actually this is not so, and the utility model takes this means by the consistent ignorance of the people of this area to make that the setting between balance block and the wheel is more firm.

The specific embodiment

As shown in Figure 5 and Figure 6, an embodiment of the present utility model comprises grab 30 and block 32, protrudes a rivet 321 on the one side of block 32.Block 32 is by rivet 321 and grab 30 riveted joints.Rivet 321 is that the mode by punching press forms, and can form auxiliary hole 322 when stamping out rivet 321 on block 32.As can be seen from Figure 6, auxiliary hole 322 is formed on the plane of block 32.

Refer again to Fig. 8, be assembled to wheel rim 34 after, block 32 is to be clamped between grab 30 and the wheel rim 34, and is the same with steel balance block shown in Figure 9, grab 30 shapes have become simply with respect to the grab shape of Fig. 2 or known steel balance block shown in Figure 3.Compared with steel balance block shown in Figure 9, in the present embodiment, only adopt a rivet that grab 30 and block 32 are set, after installing on the wheel rim, the elastic force of grab 30 is stuck in block on the wheel rim, and block 32 is closely pasted mutually with wheel rim, can not produce the phenomenon that block breaks away from.A rivet can be eliminated the uneven situation of assemblage gap that the balance block manufacturing errors causes, and that is to say, Figure 11 and situation shown in Figure 12 can not occur.The auxiliary hole of formation rivet can adopt the method processing of punching press in the plane.In addition, block 32 adopts cold drawn section bar to make.

Claims
