Specific embodiment
It is the specific embodiment of the application and in conjunction with attached drawing below, the technical solution of the application is further described,
But the application is not limited to these examples.In the following description, the specific detail of such as specific configuration and component is provided
Just for the sake of helping comprehensive understanding embodiments herein.It therefore, it will be apparent to those skilled in the art that can be to retouching here
The embodiment stated makes various changes and modifications without departing from the scope and spirit of the present application.In addition, for clarity and brevity, saving
The description to known function and construction is omited.
The embodiment of the present application shows a kind of vehicle frame rear overhang segment structure, the step height of the back segment of the vehicle frame rear overhang segment structure
It is lower, and expand the departure angle of vehicle.
Specifically, the vehicle frame rear overhang segment structure with vehicle frame middle section for being fixedly connected；The vehicle frame rear overhang segment structure has
Two girders being parallel to each other, and more crossbeams being fixed on girder；The main depth of beam is higher than vehicle frame middle section, the master
Beam is tilted to vehicle frame middle section direction, and a tilt angle is formed between horizontal plane.
It should be noted that the girder due to vehicle frame rear overhang section is tilted to vehicle frame middle section, effectively reduce public in city
The step height of automobile back segment altogether, so that more easy when passenger's disengaging is to back segment compartment.Further, since vehicle frame rear overhang section to
Top rake increases the departure angle of vehicle, improves handling capacity of the bus on bad road surface.
Further, step structure is equipped between the vehicle frame rear overhang segment structure shown in the embodiment of the present application and vehicle frame middle section,
The step structure can have two-stage step.
The vehicle frame rear overhang segment structure shown in the embodiment of the present application is further described below in conjunction with attached drawing.
With reference to Fig. 1 and Fig. 2, the vehicle frame rear overhang segment structure 1 is fixedly connected with vehicle frame middle section 2；The vehicle frame rear overhang section knot
Structure 1 has two girders 11 being parallel to each other, and more crossbeams 12 being fixed on girder；The height of the girder 11 is higher than vehicle
Frame middle section 2, the girder 11 are tilted to 2 direction of vehicle frame middle section, and a tilt angle is formed between horizontal plane.
It should be noted that back segment compartment is equipped on vehicle frame rear overhang segment structure 1, due to the master of vehicle frame rear overhang segment structure 1
The height of beam 11 is higher than vehicle frame middle section 2, forms a difference in height in interior, so that not side when passenger enters back segment compartment
Just.When girder 11 is tilted to 2 direction of vehicle frame middle section, the difference in height can be effectively reduced, passenger is facilitated to pass in and out back segment compartment.
Further, since girder 11 is tilted to 2 direction of vehicle frame middle section, so that vehicle tail is raised upwards, and then increase
The departure angle of vehicle improves handling capacity of the automobile on bad road surface.
In addition, girder 11 is tilted to 2 direction of vehicle frame middle section, so that vehicle frame rear overhang segment structure 1 and vehicle frame middle section 2 are in junction
With lower height, the structural strength and torsional property of vehicle frame junction are increased on the whole.
In the embodiment of the present application, the tilt angle is between 1 degree to 5 degree.
It should be noted that tilt angle needs to control in reasonable range, such as it is arranged between 1 degree to 5 degree.
With reference to Fig. 3, the tilt angle is specially 3.5 degree.It should be noted that the dotted line in figure is horizontal reference line.
In the embodiment of the present application, the vehicle frame rear overhang segment structure 1 is respectively arranged with left back in two outsides of two girders 11
Wheel cover 13 and off hind wheel cover 14.
It should be noted that left back wheel cover 13 and off hind wheel cover 14 are used to cover on the top of two rear-wheels.Left back 13 He of wheel cover
Off hind wheel cover 14 protrudes from the top of girder 11.
In the embodiment of the present application, the vehicle frame rear overhang segment structure 1 is equipped with step structure in the place close to vehicle frame middle section 2
15；The step structure 15 is located between two girders 11.
Since the height of the girder 11 of vehicle frame rear overhang segment structure 1 is higher than vehicle frame middle section 2, a height is formed in interior
Difference, vehicle frame rear overhang segment structure 1 are equipped with step structure 15 in the place close to vehicle frame middle section 2, and step structure 15 is for facilitating passenger
Pass in and out back segment compartment.
In the embodiment of the present application, the step structure 15 has two-stage step.In view of biggish difference in height, by step
Structure 15 is set as two-stage step, compares level-one step, and two-stage step makes passenger be easier to pass through.
In the embodiment of the present application, the girder 11 and crossbeam 12 are square tube.
It should be noted that set square tube for girder 11 and crossbeam 12, traditional coarse girder construction is eliminated, in structure
It is more flexible and light-weight, the weight of vehicle is advantageously reduced, oil consumption is reduced.
In the embodiment of the present application, it is equipped between the crossbeam on the downside of 1 both ends of the girder 11 and vehicle frame rear overhang segment structure oblique
To supporting rib 16；The skewed horizontal load muscle 16 is square tube.
It should be noted that being equipped with skewed horizontal load muscle 16 in girder 11, be conducive to increase structural strength and torsional property.
