Abstract
The invention belongs to the field of special vehicles and particularly relates to a crawler-type running system of an amphibious special vehicle. At present, suspension systems of most of special vehicles are in an elastically suspended mode, torsion bars are generally adopted as elastic components and are large in deformation, and the manufacturing process of the torsion bars can not be guaranteed. In general, crawler belts of the existing special vehicles are metal crawler belts, and consequently the weight of the whole vehicle is increased, the running speed and efficient power utilization of the whole vehicle are influenced. Moreover, in a driving device of the running system, the outer edge of a driving wheel is provided with empty grooves, the inner side of a crawler belt is provided with rubber tooth-shaped blocks, and the maintenance cost is high. The crawler-type running system of the amphibious special vehicle overcomes the defects in the design. The crawler-type running system adopts a driving method that the driving wheel is provided with a tooth-shaped structure, the crawler belt is a rubber crawler belt, and consequently strength is guaranteed and the weight of the whole vehicle is reduced. In addition, rubber springs are adopted, weight-bearing wheel shafts are connected with a bogie frame, and passing ability and flexibility of the vehicle are improved. Through adoption of a shock absorber, vibration of a vehicle body can be rapidly reduced, and running stationarity of the vehicle is improved.
Description
Technical field
Patent of the present invention belongs to the special vehicle field, relates in particular to a kind of crawler type running system of amphibious special vehicle.
Background technology
Crawler type running system is to bear body weight and guarantee the mechanism that car body travels, and in order to guarantee the normal operation of vehicle, it also plays lenitively in the face of body shock and vibration effect.Crawler type running system is comprised of suspension and running gear two parts usually, suspension fork mechanism is the parts that body and running gear are coupled together, it passes to caterpillar wheel with the weight of car body, and guarantees that vehicle is smooth-going and travel, and generally can be divided into rigidity, semi-rigid, elasticity three class formations.At present, the suspension of most of special vehiclees is resilient suspension, generally adopts torsion bar as elastic element, and the torsion bar distortion is large, and technical requirements is high, the bad assurance of manufacturing process, and maintenance cost is high; In running gear, crawler belt generally adopts metal track, has increased the weight of car load, affects the efficient utilization of car load moving velocity and power; In the actuating device of running gear, the drive wheel outer rim is with dead slot shape, the inboard band of crawler belt rubber profile of tooth piece, the engaged purpose that reaches transmitting torque of the dead slot of rubber profile of tooth piece and drive wheel outer rim, adopt this structure easily to cause maintenance cost high, often need to change the whole piece crawler belt; Adopt between car body and running gear to be rigidly connected, damping effect is poor, and car body is hit greatly.
The patent of invention content
Patent of the present invention is to overcome above-mentioned deficiency, has designed a kind of rubber caterpillar type running gear, and crawler belt is rubber belt track, it adopts the type of drive of drive wheel band tooth-shape structure, guarantee to reduce complete vehicle weight in the working strength situation as far as possible, more can adapt to the applying working condition of amphibious vehicle.In addition, adopt a kind of rubber spring, the inner sleeve of rubber spring and the inwall of rubber bonding, the outer wall bonding of overcoat and rubber, be combined with metal firmly for making rubber, a lot of grooves are arranged on inner-outer sleeve, and to increase anchoring strength, rubber spring is connected supporting wheel shaft with bogie frame, this connection mode, a caterpillar wheel can be relatively moved in vertical plane surface with respect to another caterpillar wheel or with respect to body, and this structure is fit to complex-terrain more, has improved crossing ability and the alerting ability of vehicle.Adopt shock absorber structure, strengthen damping effect, when car body passes through uneven road surface or obstacle, the stored energy of the additional deformation of elastic element is temporary transient, to release energy subsequently and cause the vibration of car body, and bumper has enough resistances and makes vibrational energy become heat energy dissipation to fall, the vibration of car body is decayed rapidly, improves cruising characteristic.
Patent of the present invention has adopted following technical scheme for achieving the above object: the running gear assembly mainly comprises rubber belt track, chassis support body, drive wheel, moping pulley component, caterpillar wheel, rubber spring, swelling device, laminated spring, caterpillar wheel rocking arm component, bumper component.It is characterized in that the metallic sheath on rubber spring and bogie frame links together by the interference deflection, caterpillar wheel rocking arm component and rubber spring spline joint, when running gear is subject to impacting, rely on the torsional deflection of rubber in rubber spring to produce the swing torsional angle, thereby realized damping and the pooling feature in the running gear.Adopt the rubber belt track of special decorative pattern, grooved bore on crawler belt with profile of tooth, and for guaranteeing the snap-in force of drive wheel and crawler belt, increases guide pin bushing in the crawler belt design and guarantees the transfer of torque function on drive wheel, and the crawler belt inboard is with the guiding tooth.The laminated spring that adopts spring steel to make between car body and bogie frame connects, and further realizes damping, the range of decrease, guarantees the smooth-ride of car body.
The beneficial effect of patent of the present invention: can realize better the multiple shock-absorbing function of car load, and easy-maintaining, cost are low, the application of special crawler belt can be born than high pulling torque and impulsive force, can not cause to take off chain, fall the tooth phenomenon.

The specific embodiment
as depicted in figs. 1 and 2, drive wheel 10 relies on bearing to be bearing in the metallic sheath of chassis support body 2, the dead slot interlock of drive wheel profile of tooth and rubber belt track 10, moping pulley component 3 is fixed by bolts on the chassis support body, caterpillar wheel 4 use bearings are bearing on the rocking arm component, rubber spring 6 relies on certain interference deflection and chassis support body to link together, caterpillar wheel rocking arm component 8 use splines are connected with rubber spring, tightening device 5 comprises the tension wheel component, adjust bolt, tension wheel support body etc., whole tightening device also is connected with rubber spring by spline at last, play damping and pooling feature, bumper component 9 is bolted on rocking arm component and chassis support body, further improve the stationarity of Vehicle Driving Cycle, laminated spring 7 is bearing between chassis support body and car body, has simultaneously the damping, buffering function.
Principle of work
When the vehicle smooth-ride, power is delivered to drive wheel 10 by propons, and drive wheel profile of tooth and rubber belt track 10 dead slot interlocks pass to crawler belt with moment of torsion, and moping pulley supports crawler belt reposefully, drives crawler belt to overtake.When running into obstacle in travelling, running gear is subject to load impacting, rubber spring 6 relies on the torsional deflection of rubber to produce certain torsional angle, realize damping and pooling feature in running gear, because the swing of each caterpillar wheel rocking arm component 8 is again separate, this structure more can adapt to complicated topographic condition.In mechanical tensioning device 5, adopt easy adjustment bolt to adjust turning an angle of tension wheel shaft, and lock corresponding nut, thereby reach the purpose of tensioned tracks.
The above is only the preferred embodiment of patent of the present invention, is not the structure of patent of the present invention is done any pro forma restriction.Every technical spirit according to patent of the present invention is to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical scheme of patent of the present invention.
