Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

In the prior art, generally, a wing plate of a cross beam is connected with a web plate or a wing plate of a longitudinal beam through a connector, the number of connecting parts is small, each connecting part is not reserved, mutual guarantee is not provided, and the connecting mode is generally adopted by penetrating through the cross beam and the longitudinal beam through a connecting bolt or a rivet to realize connection. This kind of connected mode, when the vehicle is walked or started, or when the vehicle passes through unevenness's road, the frame will receive great vibration or shake, the crossbeam of frame, the longeron, be used for the fastener of connecting or connect the position etc. all can receive the vibration, receive the vibration back in the very early stage, metal fatigue all can appear in the crossbeam of frame, the longeron, the fastener that is used for connecting or connect the position etc. can appear, can appear the fracture, fracture scheduling problem, seriously influence frame quality, influence frame life, influence the frame normal work, the traffic accident can appear even.

Like fig. 1 and fig. 4, this frame cross of technical scheme of the utility model, this frame cross has at first increased the connection position for hookup location between crossbeam and the longeron is more, and each connection position all has at least one stand-by connection, and the pterygoid lamina and the web that pass through the crossbeam and connect end plate and longeron are connected, and when a trouble and lose the connection effect, another department connects the wholeness that can also guarantee the frame, guarantees the frame and normally works.

As shown in fig. 1-4, the cross frame of the present invention includes a web 1 and wing plates 2 respectively connected to two side surfaces of the web 1, and the two ends of the web 1 are respectively provided with a connecting end plate 3. The wing plates 2 and the connecting end plates 3 are connected with the longitudinal beams 10. The crossbeam passes through the pterygoid lamina 2 of crossbeam and connects the pterygoid lamina and the web connection of end plate 3 and longeron 10, when a trouble and lose the connection effect in a department, another department connects and can also guarantee the wholeness of frame, guarantees the frame and normally works.

As shown in FIG. 2, the wing plate 2 and the web plate 1 are integrally formed, and generally the wing plate 2 and the web plate 1 are integrally formed by casting, so that on one hand, the integrity of the cross beam is ensured, the strength of the cross beam is improved, on the other hand, the cross beam is prevented from cracking in the working process of a vehicle, and the service life of the cross beam is prolonged.

As shown in fig. 3, the two ends of the wing plate 2 are respectively provided with a first connecting hole 4, the first connecting hole 4 is a long round hole, and the distance between the centers of the first connecting holes 4 is consistent with the length direction of the wing plate 2. The crossbeam passes through first connecting hole 4 and is connected with the pterygoid lamina of longeron, when the emergence vibration, the fastener of connecting crossbeam pterygoid lamina 2 and longeron can be in first connecting hole 4 micro-displacement or skew, and make and to have micro relative motion between crossbeam and the longeron, can not influence the connection of crossbeam and longeron on the one hand, on the other hand can not influence the fastener that passes in first connecting hole 4, like connecting bolt, the effectual crossbeam of having avoided, the longeron, deformation appears in fastener and the second connecting hole 4, fracture or cracked problem.

As shown in fig. 4, the connecting end plate 3 is detachably connected to the web 1. When the cross beam is connected with the longitudinal beam, the part for connecting the cross beam with the longitudinal beam is easy to deform, so that the two connecting end plates 3 and the web plate 1 can be detachably connected, the connecting end plates 3 can be conveniently replaced after the cross beam works for a certain time, and the service life of the whole cross beam or the whole frame is prolonged.

As shown in fig. 3 and 4, the web 1 and the connecting end plate 3 are respectively provided with a first mounting hole 8 and a second mounting hole 5 which are matched with each other, the web 1 and the connecting end plate 3 are detachably fixed by fasteners penetrating through the first mounting hole 8 and the second mounting hole 5, the first mounting hole 8 and the second mounting hole 5 are oblong holes, and the center distance is consistent with the length direction of the cross beam. When the cross beam is connected with the longitudinal beam, the part for connecting the cross beam with the longitudinal beam is easy to deform, so that the two connecting end plates 3 and the web plate 1 can be detachably connected, the connecting end plates 3 can be conveniently replaced after the cross beam works for a certain time, and the service life of the whole cross beam or the whole frame is prolonged. The first mounting holes 8 and the second mounting holes 5 are long round holes, so that micro-displacement deformation between the web plate 1 and the connecting end plate 3 is facilitated, and deformation caused by high-strength impact on the web plate 1 is avoided.

As shown in fig. 4, the connecting end plate 3 is L-shaped, one surface of the L-shaped connecting end plate 3 is closely attached to the inner surface of the web 1 and is provided with a second mounting hole 5, and the other surface of the L-shaped connecting end plate 3 is provided with a second connecting hole 6. The connecting end plate 3 passes through the second connecting hole 6 through a fastener and is detachably and fixedly connected with the longitudinal beam 10, and the second connecting hole 6 is a long round hole with a center distance perpendicular to the web plate 1. The second connecting holes 6 are long round holes, so that micro-displacement change between the cross beam and the longitudinal beam can be realized, and deformation or fracture of the cross beam and the longitudinal beam is avoided.

As shown in fig. 2, the inner and outer surfaces of the web 1 are both curved surfaces which are curved inward. And the inner surface of the web plate 1 is provided with a reinforcing rib 7. The setting of web structure, the atress ability of increase web 1 in vertical direction for this horizontal specially adapted heavy truck vehicle, the web 1 scheduling problem appears in further avoiding by strengthening rib 7.
