Abstract
The utility model provides a transmission auxiliary supporting device of a heavy-duty truck. The transmission auxiliary supporting device of the heavy-duty truck comprises a leaf spring cross beam, wherein two middle supporting frames are arranged between the leaf spring cross beam and a gearbox body, the two middle supporting frames are symmetrical around the center of the leaf spring cross beam, the leaf spring cross beam, the middle supporting frames and the gearbox body are connected through bolts, flat washers and spring washers are arranged above the leaf spring cross beam, and the flat washers and the spring washers are matched with the bolts. Brackets I are symmetrically and fixedly connected at two ends of the leaf spring cross beam, a bracket II is fixedly connected with the lower end of each bracket I, and the side surface of each bracket II is fixedly installed on the inner side surface of a truck frame longitudinal beam through a bolt and a self-locking nut. The transmission auxiliary supporting device of the heavy-duty truck achieves the purpose that a transmission is limited in an all-around mode, greatly reduces adverse effect caused by upward and downward jump of the transmission and torsion force on the truck, and improves safety, reliability and stability of running of the truck. In addition, the transmission auxiliary supporting device of the heavy-duty truck is simple in structure, good in supporting stability, high in vibration attenuation efficiency, compact in structure and low in cost.
Description
Technical field
The utility model relates to a kind of HD truck change-speed box auxiliary support apparatus, belongs to technical field of automobile parts.
Background technology
The employed change-speed box auxiliary support apparatus of heavy motor vehicle, its simple structure, of a great variety, performance is also uneven.At present, general bracing or strutting arrangement generally adopts middle mode of fixing with two ends.The shortcoming of this version is that the parts kind is more, and actual entrucking process is loaded down with trivial details, and cost is higher, 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, and a kind of HD truck change-speed box auxiliary support apparatus of good stability is provided.
This programme is realized by following technical measures: this HD truck change-speed box auxiliary support apparatus comprises the leaf spring crossbeam, be provided with two intermediate support beams between described leaf spring crossbeam and the gear box, two intermediate support beams are symmetrical arranged along the center of leaf spring crossbeam, leaf spring crossbeam, intermediate support beam and gear box link to each other by bolt, and leaf spring crossbeam top is provided with flat shim and the spring shim that cooperates with bolt; The two ends symmetry of leaf spring crossbeam is fixedly connected with the carriage I, and the lower end of carriage I is fixedly connected with the carriage II, and the side of carriage II is fixedly mounted on the medial surface of chassis side rail by bolt and self lock nut.
Above-mentioned carriage II is the supporting plate of horizontal positioned, and this version can better be held in the palm support plate spring crossbeam.
The beneficial effect of this programme can learn that in this HD truck change-speed box auxiliary support apparatus, mission case is captiveed joint with the leaf spring crossbeam with bolt by intermediate support beam according to the narration to such scheme, realizes above-below direction spacing of gear box.When change-speed box moved up or down with respect to vehicle frame, the leaf spring crossbeam absorbed the portion of energy that change-speed box moves up or down, change-speed box is moved up or down releive.The two ends of leaf spring crossbeam are fixed by carriage I and carriage II, when change-speed box twists, deformation can take place in the leaf spring crossbeam, absorb twist moment, thereby reduce the negative effect that twisting resistance produces vehicle, realized change-speed box omnibearing spacingly, greatly reduced change-speed box bob and twisting resistance to the harmful effect of vehicle, improved the safety that vehicle travels, reliability and stability.This apparatus structure is simple, and stability of strutting system is good, the damping efficiency height, and compact conformation, cost is lower.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.
Among the figure, 1 is the carriage I, and 2 is the leaf spring crossbeam, and 3 is bolt, and 4 is flat shim, and 5 is spring shim, and 6 is intermediate support beam, and 7 is the carriage II, and 8 is chassis side rail, and 9 is bolt, and 10 is self lock nut, and 11 is gear box.
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 HD truck change-speed box auxiliary support apparatus, as shown in Figure 1, it comprises leaf spring crossbeam 2, be provided with two intermediate support beams 6 between described leaf spring crossbeam 2 and the gear box 11, two intermediate support beams 6 are symmetrical arranged along the center of leaf spring crossbeam 2, leaf spring crossbeam 2, intermediate support beam 6 and gear box 11 link to each other by bolt 3, and leaf spring crossbeam 2 tops are provided with flat shim 4 and the spring shim 5 that cooperates with bolt 3.The two ends symmetry of leaf spring crossbeam 2 is fixedly connected with carriage I 1, and the lower end of carriage I 1 is fixedly connected with carriage II 7, and carriage II 7 is the supporting plate of horizontal positioned, and the side of carriage II 7 is fixedly mounted on the medial surface of chassis side rail 8 by bolt 9 and self lock nut 10.
When change-speed box moved up or down with respect to vehicle frame, 2 distortion of leaf spring crossbeam also absorbed the portion of energy that change-speed box moves up or down, change-speed box is moved up or down releive.The two ends of leaf spring crossbeam 2 are by carriage I 1 and carriage II 7 overlap joints, and when change-speed box twisted, deformation can take place leaf spring crossbeam 2, and absorbs twist moment, thereby reduced the negative effect that twisting resistance produces vehicle.
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.
