In the crossbeam assembly of above-mentioned automobile engine nacelle, all offer bolt hole on described erecting frame and the crossbeam, both are through the bolt and nut captive joint.Erecting frame is fixed on the two ends of crossbeam through bolt and nut, and erecting frame can be fixing with the car body welding, makes crossbeam and car body fix like this.
In the crossbeam assembly of above-mentioned automobile engine nacelle, be equipped with axle sleeve in the bolt hole of said crossbeam, the two ends of axle sleeve are against on the inwall of crossbeam.The axle sleeve two ends are against the bolt hole edge respectively, and the inwall of supporting traverse guarantees the intensity of crossbeam, prevent that crossbeam from receiving the excessive compression of bolt and nut and be out of shape.
In the crossbeam assembly of above-mentioned automobile engine nacelle, also be connected with the annex mounting bracket on the described crossbeam.The annex mounting bracket is used to install other parts in the machinery spaces such as motor, electric machine controller and change-speed box, for this crossbeam assembly provides more installation position.
In the crossbeam assembly of above-mentioned automobile engine nacelle, described annex mounting bracket and crossbeam are welded to connect.
In the crossbeam assembly of above-mentioned automobile engine nacelle, the cross section of described crossbeam can be I-shape or square.I-shape or square section bar steel load-carrying capacity are stronger, and more common on market, convenient buying.
Compared with prior art, the utility model adopts the section bar structure of steel product to substitute metal plate punching spare, and main purpose is to save the mould development expense, and has evaded the low problem of long span crossbeam middle part intensity of metal plate punching spare.And section bar thickness can freely change according to self-demand, easily realizes improving the purpose of beam strength through the adjustment wall thickness.
1. the skeleton structure of section bar steel is simple, load-carrying capacity is high.
2. after adopting section bar skeleton replacement blanked part skeleton, save the mould development expense, reduced cost of development.
3. the section bar skeleton can need not the change through mould according to the thickness of the big freedom in minor affairs adjusting type material of required load-carrying capacity, and market can directly be purchased, and it is convenient to change.
4. adopt welding fixing, make that this crossbeam assembly integral structure is more firm.
