The content of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of four-wheel vehicle frame.
The technical scheme is that：A kind of four-wheel vehicle frame, including rear frame, two girders be arrangeding in parallel, two
One end of girder is fixedly connected after being bent upwards with the rear frame, the other end of two girders extend to vehicle frame front end and to
Upper bending constitutes bumper vertical tube, and the front end of rear frame is additionally provided with the connection standpipe for connecting the girder, the girder structure
Into vertical tube end be connected with a cross bar, bent after the cross bar two ends extension its end be fixedly connected with the girder composition insurance
Thick stick transverse tube；At least two connection transverse tubes are provided between described two girders；Divide on the connection transverse tube positioned at vehicle frame front end
It is not connected with head tube beam and auxiliary girder, the end of the vehicle Guan Liang is connected with vehicle frame head, the other end of auxiliary girder is connected to another
Connection transverse tube.
Further improvement of the present invention includes：
U-shaped connecting tube is also associated with the head tube beam, the end of the U-shaped connecting tube is respectively connecting to two girders
On the bumper vertical tube of composition.
Connection inclined tube is additionally provided between the U-shaped connecting tube and the girder.
The bending section of the girder is provided with reinforcement structure.
Girder of the present invention is extended beyond head tube front portion by rear portion always, and girder upper end is connected with bumper；Bumper is passed through
Bending links together with girder again, forms a frame structure, enhances frame strength；U-shaped connecting tube elder generation and head tube
Beam links together, and two links together with girder after bending, forms a frame structure, enhances frame strength；Even
Connect inclined tube upper end to be connected with U-shaped connecting tube, lower end links together with girder, form a frame structure, enhance vehicle frame strong
Degree；Connection transverse tube two ends link together with girder, and are linked together with auxiliary girder head tube beam.Connection standpipe is girder with after
Portion's vehicle frame links together, and girder rear portion links together through bending with vehicle frame rear portion.
Bumper, head tube beam, U-shaped connecting tube, girder, connection inclined tube, form multiple framework knots vehicle frame is anterior together
Structure, reaches vehicle bumper and is merged with vehicle frame, increased the intensity of vehicle frame, and be formed in when vehicle is collided to car
The protection of anterior parts, so as to play the protection to occupant.
Bumper is merged with vehicle frame, both increased the intensity of vehicle frame, and collision is prevented again to vehicle and the wound of personnel
Evil, overall appearance is generous, gives people security protection.

Specific embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of four-wheel vehicle frame of the invention, including rear frame, two girders be arrangeding in parallel, two
One end of girder is fixedly connected after being bent upwards with the rear frame, the other end of two girders extend to vehicle frame front end and to
Upper bending constitutes bumper vertical tube, and the front end of rear frame is additionally provided with the connection standpipe for connecting the girder, the girder structure
Into vertical tube end be connected with a cross bar, bent after the cross bar two ends extension its end be fixedly connected with the girder composition insurance
Thick stick transverse tube；At least two connection transverse tubes are provided between described two girders；Divide on the connection transverse tube positioned at vehicle frame front end
It is not connected with head tube beam and auxiliary girder, the end of the vehicle Guan Liang is connected with vehicle frame head, the other end of auxiliary girder is connected to another
Connection transverse tube.
U-shaped connecting tube is also associated with the head tube beam, the end of the U-shaped connecting tube is respectively connecting to two girders
On the bumper vertical tube of composition.U-shaped connecting tube first links together with head tube beam, and two is connected to one with girder after bending
