Abstract
The utility model belongs to the field of special vehicles and particularly relates to a rubber torsional spring device of a traveling system of a crawler-type special vehicle. The rubber torsional spring device adopts the technical scheme that the rubber torsional spring device comprises a metallic inner sleeve with internal splines, a metallic outer sleeve, middle interlayered rubber, a rocker arm, a traveling wheel combined piece and a bracket. The rubber torsional spring device is characterized in that the inner sleeve of the rubber torsional spring and the inner wall of the rubber are firmly vulcanized and are adhered to each other; the outer sleeve of the rubber torsional spring and the outer wall of the rubber are vulcanized and are adhered to each other; a rocker arm shaft is connected with the internal splines of the inner sleeve through external splines of the shaft head; and the outer sleeve and a sleeve on the bracket depend on friction resistance generated by interference deformation to resist and transfer external load. The rubber torsional spring device has the beneficial effects that the rubber torsional spring device of the traveling system guarantees the driving steadiness and reliability of the vehicle; in addition, the manufacture cost and the maintenance cost are low.
Description
Technical field
The utility model belongs to the special vehicle field, relates in particular to a kind of rubber torsion spring device of tracklaying vehicle running gear.
Background technology
At present, what the running gear of traditional crawler-type special vehicle mostly adopted is torsion bar suspension system, and the technical requirements of torsion bar is relatively stricter, and bad assurance on the manufacturing process causes that manufacturing cost is high, maintenance cost is high.
The patent of invention content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and a kind of rubber torsion spring device of special vehicle running gear is provided, low cost of manufacture, and can bear vibration and the buffering in the vehicle to run, taken into account the stationarity and the reliability of vehicle '.
The utility model is for realizing above-mentioned purpose, and adopted following technical scheme: rubber torsion spring device comprises inner metal sleeve, metal-coating, the rubber of intermediate course, rocking arm, road wheel component, the support of being with female splines.It is characterized in that: the interior cover and the rubber inwall of rubber torsion spring vulcanize bonding securely; Overcoat and rubber outer wall vulcanize bonding; the male splines that rocker shaft passes through spindle nose is connected with the female splines of interior cover, and the cover on overcoat and the support leans on the friction drag of interference distortion generation with opposing and transmission external load.
The beneficial effect of the utility model: the rubber torsion spring device of this kind running gear has guaranteed the stationarity and the reliability of vehicle ', and manufacturing, maintenance cost are low.
Description of drawings
Fig. 1 is the rubber torsion spring set-up diagram in the running gear.
Fig. 2 is the section-drawing of rubber torsion spring.
1. interior cover 2. rubber 3. overcoats 4. covers 5. supports 6. rocker shaftes 7. road wheel components
The specific embodiment
As shown in Figure 1, the inwall bonding of the interior cover of rubber torsion spring 1 and rubber 2, the outer wall bonding of overcoat 3 and rubber 2, as shown in Figure 2, for making rubber and melts combine firm, inside and outside put a lot of grooves, with the increase anchoring strength.Rocker shaft 6 is connected with the female splines of interior cover 1 through the male splines of spindle nose, and the cover 4 on overcoat 3 and the support 5 leans on the friction drag of interference distortion generation with opposing and transmission external load, and road wheel component 7 usefulness bearings are bearing on the rocker shaft 6.
Principle of work
Through above-mentioned embodiment, rubber torsion spring device has guaranteed the stationarity and the reliability of vehicle '.Detailed process is following:
As depicted in figs. 1 and 2, the engagement of the female splines of the male splines of rocker shaft 6 and interior cover 1, overcoat 3 leans on interference to be out of shape with cover 4 on the support 5 to be connected; Overcoat 3 is actionless, and after the road wheel component received load or impacts, interior cover reversed with rubber; Thereby be delivered to the rubber torsion spring to load (moment of torsion); Rubber torsion spring device relies on the torsional deflection of rubber to produce the swing torsional angle, thereby has realized vibration damping in the running gear and buffering function, has guaranteed the stationarity and the reliability that go.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
