Abstract
The utility model relates to a connecting device of a tractor bridge, comprising a front axle supported by a front tire, an engine sump tank which is connected with the front axle and a rear axle supported by a rear tire; the connecting device of the utility model is characterized in that the engine sump tank is connected with the rear axle by a transition plate, therefore, the local structure of the engine sump tank is strengthened, and the transition plate can share the load by the engine sump tank, thus the load beared by the engine sump tank can be dispersed. Therefore, when the engine sump tank bears large load, a screw thread of the engine sump tank is not easily to be deformed by stretching, a connecting bolt is not loosened due to the loss of torque force, thus effectively avoiding potential safety hazard and saving cost simultaneously, in addition, the connecting device of the utility model has the advantages of simple structure and convenient installation, etc.
Description
Technical field
The utility model belongs to the trac. technical field, particularly relates to a kind of trac. crane span structure connecting device.
Background technology
Because the particularity of tractor structure, field engine serves as the crane span structure effect of trac. always, so the intensity of driving engine has been proposed very high requirement.The forward and backward bridge of trac. is direct coupled by engine sump tank in the known technology, has the connecting thread hole on the oil pan tray, is fixed by bolt, and engine sump tank will bear all load like this; Again because existing oil pan tray is generally foundry goods, when bearing big load, the engine sump tank screw thread distortion that easily is stretched under the pressure of big load, tie bolt will produce torsion and lose and become flexible, cause occurring potential safety hazard, so the oil pan tray screw thread must have higher intensity and can satisfy the requirement of bearing big load.Engine sump tank is then answered selection intensity height, material that the bearing load ability is big, adopt previous materials to cost an arm and a leg and processing difficulties, and be difficult to guarantee its requirement on machining accuracy, and process so need to be equipped with working ability equipment strong, that working accuracy is high, increased tooling cost; Adopt said structure in addition, when installing/dismounting, bring many inconvenience to the staff.
Summary of the invention
The utility model provides a kind of trac. crane span structure connecting device for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of trac. crane span structure connecting device, comprise propons that front tyre supports, with the back axle that propons bonded assembly engine sump tank, rear tyre support, it is characterized in that: engine sump tank connects back axle by attaching parts.
The utility model can also adopt following technical measures:
Described engine sump tank and back axle bonded assembly attaching parts are rebound, and rebound and engine sump tank, tractor rear axle are bolted to connection.
Advantage and the good effect that the utlity model has are: because the utility model increases a rebound between engine sump tank and back axle, by bolt engine sump tank, rebound and back axle are solidly installed, local structure are strengthened, rebound will be shared the load that oil pan tray bears, and the load that oil pan tray is born is disperseed.Therefore when engine sump tank bears big load, the distortion that is difficult for being stretched of oil pan tray screw thread, tie bolt can not produce torsion and lose and become flexible, and actv. has been avoided potential safety hazard, and the while has been saved manufacturing cost to a great extent; The utility model also has advantages such as simple in structure, easy for installation in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: 1, propons; 2, driving engine; 3, bolt; 4, back axle; 5, rear tyre; 6, rebound; 7, oil pan tray; 8, front tyre; 9, bolt; 10, bolt.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, front tyre 8 supports propons 1, and propons 1 is by the oil pan tray 7 of bolt 9 connection driving engines 2, and engine sump tank connects rebounds 6 by bolt 3, and rebound 6 connects the back axle 4 of rear tyre 5 supports by bolt 10.
Owing to increase a rebound 6 between driving engine 2 oil pan trays 7 and the back axle, make driving engine 2 oil pan trays 7 by bolt, rebound 6 is solidly installed by bolt 10 with back axle, the oil pan tray local structure are strengthened, rebound 6 will be shared the load that oil pan tray 7 bears, and make that oil pan tray 7 bearing loads obtain disperseing.Therefore when bear big load, the distortion that is difficult for being stretched of oil pan tray 7 screw threads, tie bolt can not produce torsion and lose and become flexible, and actv. has been avoided potential safety hazard, and the while has been saved cost in to a great extent; The utility model also has advantages such as simple in structure, easy for installation in addition.
