Abstract

The utility model discloses a straight gimbal axis of a lorry, which changes a solid axis of the original design into a three-axis combined structure, wherein main axes on both ends respectively form shrink and interference fit with axis holes of the lower part of a heightening bracket, both ends of a straight connecting axis in the middle are erected in an axis trough of the upper part of the heightening bracket, the connecting axis is made of hollow steel pipe materials, and the positions on both of the two ends of the connecting axis, which are fixedly matched with press caps and bolts, are is welded with round steel. Because the connecting axis is made of straight steel pipe materials, the utility model eliminates the stress concentration at the supporting position, increases the intensity and the elasticity, prevents axis fracture and reduces maintenance, and meanwhile, the axial dimension can be optionally adjusted.

Description

The straight formula balance suspension of autotruck axle

The utility model relates to the straight formula balance suspension of a kind of autotruck axle, belongs to mechanical, the vehicular spare parts field.

Modified reprocessing behind solid round steel hot forming of existing autotruck balance suspension axle employing, the two ends and the support hot charging interference fit of axle, because after bearing is shaped, the support inboard, curvature near the support portions axle is big, radius is little, to assemble the magnitude of interference big in addition, stress concentration causes this position strength degradation, especially excessively overload, cause the elasticity of axle relatively poor, the off-axis phenomenon is comparatively serious, when after off-axis several times, and big distortion of automobile, mounting hole is apart from displacement, cause when refilling new, the bolt hole that must rebuild big rack brings very big inconvenience apart from the position to maintenance.

The utility model provides the straight formula balance suspension of a kind of autotruck axle at the problems referred to above, and it can eliminate axle body stress, gains in strength, increases elasticity, prevents off-axis, reduces maintenance capacity.

Task of the present utility model is finished as follows: this is novel to change an intrinsic solid bearing into three sections axle unitized constructions, wherein, the two ends main shaft respectively with increase support bottom axis hole hot charging interference fit, middle straight formula adapter shaft two ends frame is in increasing support top axial trough, this adapter shaft adopts hollow steel pipe material, and at both ends welds round steel with gland, bolted matching part.

It is three sections axle unitized constructions that the utility model is changed solid bearing of traditional autotruck balance suspension axle, totally be divided into two positions up and down, because adapter shaft adopts straight formula tube material, eliminated the stress concentration at supporting position, increase intensity, increased elasticity, prevent off-axis, reduce maintenance capacity, since middle straight formula adapter shaft two with increase support and adopt gland, bolt form, axial dimension is adjusted arbitrarily, be not subjected to the vehicle frame deformation constrain, its two ends are increased support height and should be able to be guaranteed can not interfere with propeller-shaft.

Below in conjunction with accompanying drawing the utility model being done a nearly step describes in detail:

Fig. 1 is the utility model integral structure figure

Fig. 2 is former load-carrying automobile balance suspension shaft

With reference to accompanying drawing 1,2, the utility model adopts and changes an intrinsic solid bearing into three sections axle unitized constructions, wherein, two ends main shaft [1] respectively with increase support [2] bottom axis hole hot charging interference fit, middle straight formula adapter shaft [3] two headstocks are in increasing support top axial trough, this adapter shaft adopts hollow steel pipe material, and at both ends welds round steel with gland [4], bolt [5] rigid fit position.

Claims

1, the straight formula balance suspension of a kind of autotruck axle, it is characterized in that: the utility model adopts and changes an intrinsic solid bearing into three sections axle unitized constructions, wherein, two ends main shaft [1] respectively with increase support [2] bottom axis hole hot charging interference fit, middle straight formula adapter shaft [3] two ends frame is in increasing support top axial trough, this adapter shaft adopts hollow steel pipe material, and at both ends welds round steel with gland [4], bolt [5] rigid fit position.
