Abstract

The utility model relates to a lower beam structure of a heavy-duty truck engine, which comprises n-shaped main body; the edge of the n-shaped main body is a strengthened transitional arc with multiple curved surfaces; and two lug parts of the n-shaped main body are connected with a lining plate with the curved surface. With the lower beam structure, the whole cross section factor of the part is effectively improved, the comprehensive yield strength of the part is improved, and the service life of the structure on the whole machine is prolonged.

Description

A kind of heavy card driving engine cross sill structure

Technical field

The utility model belongs to the vehicle structure technical field, relates to a kind of vehicle motor cross sill, especially a kind of heavy card driving engine cross sill structure.

Background technology

In the prior art, the driving engine cross sill of heavy duty truck is generally U type structure to abdicate installing space to driving engine.Though it is simple that the crossbeam of this structure has technology; lower-cost advantage; but because in the vehicle operating process; the cross sill stressing conditions is comparatively severe; be subjected to the restriction of this structure, cross sill particularly crackle occurs from the commissure through the situation that regular meeting's appearance damages because of insufficient strength (especially antitorque limited); lost efficacy until drawing crack, and needed to change.Therefore, need the mechanism of prior art be improved, thereby improve its intensity.

The utility model content

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of heavy card driving engine cross sill structure is provided, and this beam structure can improve the comprehensive yield strength of part by reasonable structural design, increases the service life.

The purpose of this utility model solves by the following technical programs:

This heavy card driving engine cross sill structure comprises that seamed edge is the " main body that many curved surfaces are strengthened transition arcs, is connected with the liner plate of curved surface in described " main body two ears.

The asymmetric hollow out of above " main body two ear's center rectangles.

The center of above " main body offers through hole.

The improvement design of the utility model by on the existing structure basis effectively increased under the complicated applied force situation, and the antitorque and bending resistant section coefficient of part prolongs part part service life on car load.

Description of drawings

Fig. 1 is a front elevation of the present utility model;

Fig. 2 is a lateral plan of the present utility model;

Fig. 3 is the left view of Fig. 1.

Wherein: 1, " main body; 2, liner plate; 3, through hole; 4, many curved surfaces are strengthened transition arc.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Referring to Fig. 1, Fig. 2 and Fig. 3, heavy card driving engine cross sill structure of the present utility model comprises that seamed edge is the " main body 1 that many curved surfaces are strengthened transition arc 4, is connected with the liner plate 2 of curved surface in 1 liang of ear of " main body.Offer through hole 4 at the center of " main body 1.And in the asymmetric hollow out of " main body 1 liang of ear center rectangle.

In sum, the utility model is analyzed former flat board " a few word " type structure, its stressed thin spot is a seamed edge, by changing flat board " a few word " type is the mode that the many curved surfaces of seamed edge are strengthened transition arc " a few word " type, in the liner plate and the asymmetric hollow out of center rectangle (as Fig. 1) of " a few word " type two ears connection curved surface, intermittently weld the junction, edge, riveted structure is taked in heart portion junction, increases the part whole synthesis and be subjected to force coefficient, improve intensity, prolong the service life of part on the car load.Because the utility model has increased part global sections coefficient, therefore improved the comprehensive yield strength of part, prolonged its service life on car load.

Claims
