Technical Field

The utility model relates to a sub vehicle frame structure, especially a non-frame structure sub vehicle frame.

Background

The automobile front auxiliary frame assembly in the prior art comprises a front auxiliary frame upper plate, a front auxiliary frame lower plate, a horn tube, a swing arm support upper plate, a swing arm support lower plate, a suspension mounting support, a mounting sleeve, and a rectangular box body structure surrounded by the front auxiliary frame upper plate and the front auxiliary frame lower plate; the front and rear mounting brackets are connected between the upper plate and the lower plate of the front auxiliary frame; the horn tube and the sleeve are welded together. Because preceding sub vehicle frame assembly formula rectangle box body structure as an organic whole, in order to keep this structure at the deformation, be provided with the enhancement support in rectangle box body inside, play the supporting role through support protrusion and support piece, guarantee overall structure's stability. But also has the defects that the welding distance between the horn tube and the sleeve is closer to the edge line of the horn tube, which is not beneficial to welding, and the size of the horn tube is limited due to the space arrangement; the front point support of the swing arm is arranged by relating to a driving shaft of a front auxiliary frame, so that the Z-direction section of the structure is too high, and interference is easy to generate to cause abnormal sound in the running process of a real vehicle; the swing arm front point support is connected transition region structure weak with sub vehicle frame middle part, and the swing arm support has the risk of failure when endurance test.

Disclosure of Invention

The utility model discloses solve above-mentioned prior art's shortcoming, provide a configuration optimization, more durable non-frame structure sub vehicle frame.

The utility model provides a technical scheme that its technical problem adopted: this kind of non-frame structure sub vehicle frame mainly includes goat's horn pipe, swing arm front point support, upper plate and hypoplastron, and two goat's horn pipes and swing arm front point supports are located the anterior both ends of upper plate respectively, and upper plate and hypoplastron cooperate from top to bottom to connect fixedly, and the both ends sub-unit connection at upper plate rear portion is fixed with swing arm rear point hypoplastron, and goat's horn pipe snap-on is fixed on the upper plate, and the tip of goat's horn pipe is embedded to be fixed with the sleeve pipe.

The end part of the horn tube is of a semicircular structure, and the sleeve is embedded into the semicircular structure and is fixedly connected through welding.

The swing arm front point support is of a U-shaped structure, and the U-shaped opening of the swing arm front point support faces outwards.

The inner side of the upper plate is provided with a suspension reinforcing support, an arc-shaped reinforcing plate, a stabilizer bar mounting reinforcing plate and a steering engine mounting sleeve, the front side of the upper plate is provided with a suspension supporting support, and the rear side of the upper plate is provided with a wire harness mounting support.

The utility model discloses profitable effect is: the utility model discloses the structure has carried out configuration optimization to key part goat's horn pipe and swing arm front point support, has reduced the interference abnormal sound of whole car to optimize the welding position of sleeve pipe and goat's horn pipe, made the welding process degree of difficulty reduce, reduced earlier stage mould cost input.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, this kind of non-frame structure sub vehicle frame mainly includes goat's horn pipe 1, swing arm front point support 2, upper plate 3 and hypoplastron 6, and two goat's horn pipes 1 and swing arm front point support 2 are located the anterior both ends of upper plate 3 respectively, and swing arm front point support 2 is U type structure, and the U type opening part of swing arm front point support 2 is towards the outside. The upper plate 3 and the lower plate 6 are connected and fixed in a vertically matched mode, the lower portions of the two ends of the rear portion of the upper plate 3 are fixedly connected with the lower plate 5 of the rear point of the swing arm, the horn tube 1 is directly fixed on the upper plate 3, and the end portion of the horn tube 1 is fixed with the sleeve 10 in an embedded mode. The end part of the goat's horn pipe 1 is a semicircle structure, and the sleeve 10 is embedded into the semicircle structure and is fixed by welding. The inboard of upper plate 3 is equipped with suspension reinforcing bracket 8, arc distribution's reinforcing plate 7, stabilizer bar installation reinforcing plate 9 and steering engine installation sleeve pipe 11, and the front side of upper plate 3 is equipped with suspension support holder 4, and the rear side is equipped with pencil installing support 12.
