The utility model content
The purpose of the utility model provides a kind of reasonable in design, light weight, intensity and the good full carrying natural fuels bus frame structure of performance.
The technical scheme that realizes the utility model purpose is a kind of full carrying natural fuels bus frame structure, and said vehicle frame and vehicle body are rigidly connected, and comprise the leading portion vehicle frame, stage casing vehicle frame and the back segment vehicle frame that are welded to each other; Said stage casing vehicle frame comprises many crossbeams and two longerons, and the two is separated out the steel cylinder installing space; Said longeron has two, is rectangular tube.
Said crossbeam comprises steel cylinder mounting rail and body contact beam; Said every steel cylinder mounting rail is provided with two inverted U grooves.
Said steel cylinder through anchor ear be bolted in the inverted U groove of steel cylinder mounting rail, all have rubber flexible to be connected between anchor ear and the steel cylinder and between steel cylinder mounting rail and the steel cylinder.
Said every longeron comprises longeron, following longeron, straight beam and raker beam; Said straight beam is connected longeron and following longeron with raker beam.
Said straight beam has seven, respectively is provided with two in the rear and front end of longeron, and its excess-three root is evenly distributed between second and the second from the bottom straight beam; Between per two straight beams a raker beam is set between said second and the second from the bottom straight beam.
Adopted technique scheme; The utlity model has following beneficial effect: the vehicle frame of (1) the utility model is through being rigidly connected with vehicle body; Make vehicle body and underframe form a unified integral body, whole underframe adopts a large amount of high strength rectangular tubes to be welded, and compares with traditional trough girder structure; At aspects such as vehicle frame bulk strength, rigidity and lightweights tangible advantage is arranged, greatly reduce the weight of whole vehicle frame.
(2) the utility model is arranged in the stage casing with steel cylinder, and distribution of axle load is more reasonable.
(3) the utility model is processed crossbeam on the vehicle frame of stage casing cleverly, makes it can be used for fixing steel cylinder, and a beam is dual-purpose, has made full use of the space.
(4) the body frame structure for automotive design science of the utility model, mature and reliable, manufacturability, commonality are good.
(5) the natural fuels passenger vehicle adopts the body frame structure for automotive of the utility model, can be so that the steel cylinder arrangement convenience, and advantage such as the layout with chassis is compact, in light weight, and the interior space degree of utilization is high, and vehicle's center of gravity is low, and distribution of axle load is reasonable.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
