The utility model content

The technical problems to be solved in the utility model provides a kind of automobile front subframe that makes the automobile front chamber compact conformation.

For solving the problems of the technologies described above, a kind of automobile front subframe of the utility model comprises crossbeam and inner high voltage forming U type pipe, and this U type Guan Youyi limit traversing section and two vertical section constitute, and this crossbeam is fixed between the end of this two vertical section; On the connecting portion of this two vertical section and this traversing section, be formed with the front body connecting panel assembly that to captive joint with vehicle body respectively; Be formed with the rubber bearing adapter plate assembly of captiveing joint on the end of this two vertical section with vehicle body; Wherein, but described traversing section is provided with stationary engine first support that suspends, but described crossbeam is provided with second support that stationary engine suspends; But this first support cooperates stationary engine to suspend with this second support; Described crossbeam is provided with fixedly the 3rd support of steering box.

As a kind of improvement of the present utility model, wherein, be respectively equipped with the fixedly mounting hole of front stabilizer bar on the position between the end of described two vertical section and the described crossbeam.

As a kind of improvement of the present utility model, wherein, the two ends of described crossbeam are separately fixed on the described two vertical section sides; Offer the first front swing arm mounting hole on the both ends of this crossbeam respectively, offer the second front swing arm mounting hole on the position of the close described traversing section of this two vertical section respectively; This first front swing arm mounting hole cooperates fixedly front swing arm with this second front swing arm mounting hole.

As a kind of improvement of the present utility model, wherein, be respectively equipped with on the end of described two vertical section and be convenient to fore sub frame and be installed to knock hole support on the vehicle body.

The utility model compared with prior art, a kind of automobile front subframe of the utility model, but be provided with stationary engine first support that suspends because U type pipe is put into traversing section, but crossbeam is provided with second support that stationary engine suspends; But first support cooperates stationary engine to suspend with second support; Also be provided with fixedly the 3rd support of steering box on the crossbeam.Therefore, after on the automobile front subframe engine mounting and steering box being installed, automobile front chamber inner structure compactness.Owing to automobile front subframe being fixed on the vehicle body, easy for installation again by the rubber bearing adapter plate total performance on the end of front body connecting panel assembly on the connecting portion of two vertical section and traversing section and two vertical section.Front stabilizer bar can be connected on the end and the mounting hole on the position between the described crossbeam of two vertical section, and front swing arm can be connected on the both ends of crossbeam and on the position of the close traversing section of two vertical section, after automobile front subframe was installed front stabilizer bar and front swing arm, the structure in the automobile front chamber was also very compact.On the end of two vertical section, be provided with the knock hole support, when fore sub frame is installed, can fore sub frame be in place like this by the knock hole on the support.
