Further, the junction of described the first beam, this second beam and described front leg strut case and described rear support leg case is provided with reinforced rib.
Further, described vehicle frame back segment also comprises crossbeam, and the two ends of described crossbeam are connected on described the first beam and described the second beam.
Further, described vehicle frame back segment also comprises connector, and the two ends of described connector are connected on described the first beam and described the second beam.
Further, described connector is the revolution support ring.
Further, described connector is welded on described the first beam and described the second beam.
The first beam of the present utility model and the second beam have less volume with respect to existing single-spar construction, therefore, can reduce the weight of this vehicle frame back segment, save materials, reduce cost of manufacture.In addition, on the basis that achieves the above object, this vehicle frame back segment is provided with two beams, i.e. this first beam and this second beam can improve the torsional property of this vehicle frame back segment.
A kind of car hosit that is provided with above-mentioned vehicle frame back segment that the utility model provides, because above-mentioned vehicle frame back segment has above-mentioned technique effect, therefore, the car hosit that is provided with this vehicle frame back segment also has corresponding technique effect.
Description of drawings
