Abstract
The utility model discloses a vehicle frame connecting device, which comprises an upper connecting piece and a lower connecting piece, wherein the upper connecting piece is provided with a boss; the lower connecting piece is provided with a groove matched with the boss; and the upper connecting piece is connected with the lower connecting piece via a bolt. The upper connecting piece is a welded part of a sheet with a boss and a groove-shaped bending part; and the upper connecting piece is welded with an auxiliary vehicle frame of a special vehicle on a longitudinal vertical plane. The lower connecting piece is a welded part of a sheet with a boss and a groove-shaped bending part; and the lower connecting piece is connected with a chassis vehicle frame crossbeam via three connecting bolts on the longitudinal vertical plane. The bolts are used in conjunction with nuts and spring washers to connect the upper connecting piece and the lower connecting piece together, and the bosses and the grooves form anti-thrust clamping slots.
Description
Technical field
The utility model relates to a kind of vehicle frame connecting device, is specifically related to the connecting device between a kind of subframe and the chassis frame crossbeam.
Background technology
At present, subframe is connected with the chassis frame crossbeam, upper connector and the following attaching parts junction between the two that is connected on the chassis frame crossbeam that it is connected on the subframe are directly to pass through the plain bolt bonded assembly, do not have displacement space between its upper connector and the following attaching parts.The mode that is rigidly connected like this, make between subframe and the chassis frame crossbeam and do not have displacement space, the stress that subframe and chassis frame crossbeam are born is bigger, in real work, described junction withstands shocks and the poor ability of shearing stress, be easy to generate stress concentration, thereby cause the plastic deformation of subframe, influence its service life.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and the connecting device between a kind of subframe and the chassis frame crossbeam is provided, and makes it produce displacement space when subframe is subjected to greater impact, reduces the suffered stress of subframe, improves its service life.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of vehicle frame connecting device comprises upper connector and a following attaching parts; Upper connector is provided with a boss; Following attaching parts is provided with a groove that is complementary with boss; Upper connector passes through bolted connection with following attaching parts.
Upper connector is to have the plate of boss and the weldment of grooved bending part; Upper connector and subframe connect by being weldingly connected on longitudinal vertical plane.
Described attaching parts down is to have the plate of groove and the weldment of grooved bending part; Following attaching parts is connected by 3 tie bolts on longitudinal vertical plane with the chassis frame crossbeam.
Bolts and nuts, spring washer are used, and upper connector and this time attaching parts are linked together, and its boss and groove form the thrust draw-in groove.
The beneficial effects of the utility model are: during by the connecting device between subframe in the utility model and the chassis frame crossbeam, can realize stable connection the between subframe and the chassis frame crossbeam, and when the load that withstands shocks is big, formed thrust draw-in groove can produce the relative displacement of vertically going up certain limit again between the upper and lower attaching parts, reduce the suffered stress of subframe, and then improve subframe service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1.
Wherein, 1, subframe, 2, upper connector, 21, boss, 3, attaching parts down, 31, groove, 4, the chassis frame crossbeam, 5, bolt, 6, spring washer, 7, nut, 8, tie bolt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
In Fig. 1 and Fig. 2, subframe 1 is connected into one by upper connector 2 and following attaching parts 3 with chassis frame crossbeam 4, constitutes the connecting device between subframe 1 and the chassis frame crossbeam 4.This subframe comprises that tank truck, Mixer Truck etc. do not possess the subframe of lifting functional device, and the version of this subframe is rectangular tube or L template material bending part.Upper connector 2 is for having the plate of boss 21 and the weldment of grooved bending part, and following attaching parts 3 is for having the plate of groove 31 and the weldment of grooved bending part.Upper connector 2 connects by being weldingly connected on longitudinal vertical plane with subframe, and following attaching parts 3 is connected by 3 tie bolts 8 on longitudinal vertical plane with the chassis frame crossbeam.Then be connected by 2 bolts 5 between the transverse horizontal face between upper connector 2 and the following attaching parts 3, bolt 5 is used with nut 7, spring washer 6, and at its corresponding position, boss 21 forms the thrust draw-in grooves with groove 31.When the load that withstands shocks is big, subframe 1 and upper connector 2 can produce relative displacement by relative chassis frame crossbeam 4, this moment, the side surface of boss 21 contacted with the opposite inner face of groove 31, bear certain stress, guaranteeing that subframe 1 is connected failure-free and makes simultaneously to adorn partly and between the chassis on whole certain displacement space is arranged again with chassis frame crossbeam 4 thus, thereby dress and the stress value that is subjected to of subframe in the minimizing are with raising subframe service life.
