Abstract
The utility model provides a turning hoist cylinder installation axle of a heavy-duty truck. The turning hoist cylinder installation axle seat of the heavy-duty truck comprises an axle seat body which is fixedly connected with a truck frame, wherein the axle seat body protrudes towards the outer side of the truck frame and is of a hollow cast integrated structure, and the structure enables casting flaws of the axle seat body to be not prone to appearing. A through hole is formed in the protruding end of the axle seat body, a bolt which penetrates through the truck frame from inside to outside is arranged on the truck frame, and the bolt further penetrates through the through hole formed in the axel seat body and a turning hoist cylinder arranged outside the axle seat in sequence. When a cab goes up, turns over and goes down, the axle seat body bears supporting force and impulse load of the cab. When the axle seat body fractures, the bolt can be connected with the turning hoist cylinder and the frame and plays a role in safety protection. Therefore, stability and safety of the cab are improved in the process of overturning of the cab.
Description
Technical field
The utility model relates to a kind of heavy duty truck commentaries on classics lifting and fall oil cylinder installation axle bed, belong to technical field of automobile parts.
Background technology
At present, the operator's compartment hoisting system adopts operator's compartment and changes lifting and fall oil cylinder and be connected, change lifting and fall oil cylinder and be connected lifting, upset and the decline of realization operator's compartment with vehicle frame.Change lifting and fall being connected between oil cylinder and the vehicle frame axle bed need be installed, and traditional commentaries on classics lifting is fallen oil cylinder and axle bed is installed is adopted and process screw thread at axle bed, will change lifting and fall oil cylinder and be assemblied on the axle bed and by nut and fix.The shortcoming of this structure is: if the axle bed fracture does not have safeguard procedures in the operator's compartment lifting process, have certain potential safety hazard, existing in prior technology weak point that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, falls oil cylinder installation axle bed and provide the good heavy duty truck of a kind of safety performance to change lifting.
This programme is realized by following technical measures: this heavy duty truck commentaries on classics lifting is fallen oil cylinder installation axle bed and is comprised the axle bed body of captiveing joint with vehicle frame, described axle bed body is the casting integrated type structure to vehicle frame outside projection and hollow, the protruding end of axle bed body is provided with through hole, passed bolt on the vehicle frame from inside to outside, oil cylinder falls in the commentaries on classics lifting that this bolt also passes the through hole on the axle bed body successively and is positioned at the axle bed body outside, and the bolt end is provided with and changes lifting and fall the oil cylinder nut engaged.
The diameter of above-mentioned through hole is 15mm.
The diameter of above-mentioned bolt is 14mm.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this heavy duty truck changes lifting and falls in the oil cylinder installation axle bed, described axle bed body is that this version makes the axle bed body be not easy to occur foundry defect to the casting integrated type structure of vehicle frame outside projection and hollow.The protruding end of axle bed body is provided with through hole, has passed bolt on the vehicle frame from inside to outside, and the through hole that this bolt also passes on the axle bed body successively falls oil cylinder with the commentaries on classics lifting that is positioned at the axle bed body outside.Operator's compartment is when lifting, upset and decline, the axle bed body bears the impact load of bearing force and operator's compartment, and after fracture appearred in the axle bed body, bolt can connect the commentaries on classics lifting and fall oil cylinder and vehicle frame, play the safety precaution effect, improved stability and the safety of operator's compartment in switching process.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is A-A sectional structure scheme drawing among Fig. 1.
Among the figure, 1 is to change lifting to fall oil cylinder, and 2 is tie bolt, and 3 is the axle bed body, and 4 is bolt, and 5 is vehicle frame, and 6 is nut.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of heavy duty truck changes lifting and falls oil cylinder installation axle bed, as depicted in figs. 1 and 2, it comprises the axle bed body 3 of captiveing joint by tie bolt 2 with vehicle frame 5, described axle bed body 3 is to vehicle frame 5 outside projectioies, and the casting integrated type structure of hollow, the protruding end of axle bed body 3 is provided with the through hole that diameter is 15mm, passing diameter on the vehicle frame 5 from inside to outside is the bolt 4 of 14mm, the through hole that this bolt 4 also passes on the axle bed body 3 successively falls oil cylinder 1 with the commentaries on classics lifting that is positioned at axle bed body 3 outsides, bolt 4 ends are provided with and change lifting and fall oil cylinder 1 nut engaged 6, to change lifting by bolt 4 and nut 6 and fall oil cylinder 1 and be fixed on the axle bed body 3, will change lifting by axle bed body 3 then and fall oil cylinder 1 and be installed on the vehicle frame 5.When operator's compartment lifting, upset and decline; axle bed body 3 bears the impact load of bearing force and operator's compartment; if fracture appears in axle bed body 3; bolt 4 can connect the commentaries on classics lifting and fall oil cylinder 1 and vehicle frame 5; thereby play a protective role; this structural safety is reliable, has avoided the potential safety hazard that exists in the driver's cab turnover process.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model; do not repeat them here; in the above-described embodiments; preferred forms of the present utility model is described; the utility model is not limited in the above-mentioned specific embodiment; the variation that those of ordinary skills make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
