Abstract
The utility model relates to a locomotive wheel, in particular to a multi-layer rubber elastic wheel. The locomotive wheel comprises a wheel tire, a wheel core, a wheel core patch and a multi-layer rubber, wherein, all the wheel tire, the wheel core and the wheel core patch are disc-shaped, a shaft hole is formed in the center, a plurality of circular grooves concentric with the shaft hole are formed in two discs of the wheel tire respectively, an inner handle latch is formed on the edge of the shaft hole thereof, a lug boss is formed in the center of the wheel core, a plurality of circular grooves concentric with the shaft hole are formed at the periphery of the lug boss, a plurality of circular grooves are formed at the periphery of the shaft hole of the wheel core patch, the wheel core and the wheel core patch are provided with outer handle latches respectively, the wheel tire is sleeved on the wheel core, and the wheel core is connected with the wheel core patch through a fastening bolt. The wheel core, a bearing, a shaft box, a brake wheel, a shaft and accessories on the shaft are switched into elastic mass through a wheel flange so that the unsprung mass is sufficiently lessened, and the rubber layer also can adopt an appropriate inflatable structure. In addition, the unsprung steel mass is reduced to about 380 kilograms so as to fully achieve the application purpose.
Description
Technical field:
It is right that the utility model relates to locomotive wheel, and especially a kind of multilayer rubber elastic wheel is right.
Background technology:
What use now in the transportation of track traffic rolling stock is that the rigidity wheel is right, and the rigidity quality is 1300 to 1500 kilograms under its spring, and roadbed, sleeper and rail are had very big infringement; Bearing installation is worked in the rigidity body, and the rigidity vibration causes the bearing operating mode extremely abominable; The rigidity disc is in service axially, radial stress is concentrated, and operating mode is abominable, and the technological requirement strictness causes major traffic accidents easily; Noise pollutes environment greatly.Thereby capacity, safety and the economic benefit of rail transport have been restricted to a great extent.
Summary of the invention:
The technical problems to be solved in the utility model is: provide a kind of by multilayer rubber being set and then alleviating unsprung weight, thereby improve safety, economic benefit, the rail transport ability of rail transport, reduce environmental noise and pollute, the multilayer rubber elastic wheel that increases the trolley coach driving comfort is right.
The technical scheme that technical matters adopts is: a kind of multilayer rubber elastic wheel is right, comprise: rim, core wheel, core wheel is mended plate, binding bolt, multilayer rubber, described rim, core wheel, it is all in the form of annular discs that core wheel is mended plate, the center is provided with axis hole, described rim two cards are respectively arranged with a plurality of round groove concentric with axis hole in it, its axis hole edge is provided with interior latch, described core wheel center is provided with boss, be provided with a plurality of round groove concentric around the boss with axis hole, the axis hole that described core wheel is mended plate is provided with a plurality of round grooves on every side, described core wheel and core wheel are mended plate and are respectively arranged with outer latch, described rim is enclosed within on the core wheel, and core wheel is mended plate with core wheel and is connected by binding bolt.
Compared with prior art, the beneficial effect that the utlity model has is:
Wheel rim is independent of in the multilayer rubber, it is unique unsprung weight, core wheel, bearing, axle box, brake wheel, axle and axle are gone up annex be transformed into elastic qualities, and then alleviated unsprung weight fully, and applying working condition that can be right according to wheel, parameters such as the number of plies of concrete selection rubber, thickness, elasticity modulus, rubber layer also can use suitable inflatable structure.The rigidity quality is reduced to about 380 kilograms under the spring, has all reached application target.
Description of drawings:
Fig. 1 is a mounting structure scheme drawing of the present utility model.
Fig. 2 is a core wheel structural representation of the present utility model.
Fig. 3 is a core wheel wild card toothing scheme drawing of the present utility model.
Fig. 4 is the structural representation of rim of the present utility model.
Fig. 5 is a latch structural representation in the rim of the present utility model.
Fig. 6 is the structural representation that core wheel of the present utility model is mended plate.
Fig. 7 is that core wheel of the present utility model is mended latch structural representation in the plate.
Among the figure: core wheel 1, multilayer rubber 2, rim 3, core wheel is mended plate 4, binding bolt 5, the outer latch 6 of core wheel, latch 7 in the rim, core wheel are mended the outer latch 8 of plate, boss 9, groove 10.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of multilayer rubber elastic wheel is right, by rim 3, core wheel 1, core wheel is mended plate 4, binding bolt 5, multilayer rubber 2 constitutes, described rim 3, core wheel 1, it is all in the form of annular discs that core wheel is mended plate 4, the center is provided with axis hole, 3 liang of cards of described rim are respectively arranged with a plurality of round groove 10 concentric with axis hole in it, its axis hole edge is provided with interior latch 7, described core wheel 1 center is provided with boss 9, be provided with a plurality of round groove 10 concentric around the boss 9 with axis hole, the axis hole that described core wheel is mended plate 4 is provided with a plurality of round grooves 10 on every side, described core wheel 1 is mended plate 4 with core wheel and is respectively arranged with outer latch 8, described rim 3 is enclosed within on the core wheel 1, and core wheel 1 is mended plate 4 with core wheel and is connected by binding bolt 5.
The utility model principle of work is summarized as follows:
At first multilayer rubber 2 is embedded in the groove 10 of rim 3, then core wheel 1 is installed in the rim 3 and matches with core wheel benefit plate 4, multilayer rubber 2 is filled in the space that forms, axle sleeve is contained on the core wheel 1, and load onto the last annex of axle box, brake wheel and axle and can use.
