Abstract
Provided is a flexible rubber connecting joint for a rolling stock. The flexible rubber connecting joint comprises a jacket (1), rubbers (2) and a spindle (3). Two ends of the spindle (3) are provided with through holes (5) for connecting vehicle vibration sources. The rubbers are sleeved to the central portion of the spindle (3) and is bonded and connected with the spindle (3). The jacket (1) is sleeved on the rubbers (2) and is bonded and connected with the rubbers (2). The part where the jacket (1) and two ends of the rubbers (2) are bonded and the part where the spindle (3) and two ends of the rubbers (2) are bonded are respectively provided with structural grooves (4). Two ends of the rubbers (2) are inserted into the structural grooves (4), respectively. The rubbers are firmly bonded with the jacket and the spindle, achieving good noise reduction effect, enhancing the safety of rolling stocks which are running and increasing the reliability of product quality guarantee.
Description
Technical field
The utility model relates to field of track traffic, specifically, relates to a kind of used for rolling stock and flexibly connects rubber arthrosis.
Background technology
At present, used for rolling stock in the one class track traffic flexibly connects rubber arthrosis and mainly has following shortcoming: 1, in forming process, the flowing power of rubber and overcoat and mandrel junction increases greatly, the mobile loss of pressure that makes of rubber is serious, thereby cause overcoat, adhesive failure appears in the junction of mandrel and rubber often, reduce the qualification rate of product greatly, 2, this series products is installed in the car body bottom of rolling stock, often contact with pollutants, anticorrosion class requirement is higher, therefore generally take the mode of bethanizing, in the electroplating process, because the abutting edge rubber layer of structural metal-rubber is thinner at present, when electric current passes through, will cause adhesive failure than thin rubber layer puncture easily.3, for the bonding product that has defective, if there is leak in check, the safety when influence rolling stock and move and the reliability of product design supportability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the firm and used for rolling stock that effect of vibration and noise reduction is good of a kind of rubber and overcoat and mandrel bonding to flexibly connect rubber arthrosis.
The technical scheme that realizes above-mentioned purpose is: a kind of used for rolling stock flexibly connects rubber arthrosis, comprise overcoat, rubber and mandrel, the mandrel two ends have the through hole that is used to connect the Vehicular vibration source, rubber coating at mandrel middle part and with the mandrel bonding connection, overcoat is enclosed within on the rubber and with rubber bound and is connected, and the bonding part at the bonding part at overcoat and rubber two ends and mandrel and rubber two ends has been opened the structure groove respectively, and in the difference embedded structure groove of the two ends of rubber.
The cross-sectional plane of structure groove is a circular arc.
After adopting technique scheme, the through hole at mandrel two ends produces soruce of vibration with rolling stock and partly is connected, and reaches the effect of vibration and noise reducing after vibration wave decays amplitude, oscillation frequency is changed by rubber part.Because overcoat and the bonding part at rubber two ends and the bonding part at mandrel and rubber two ends have been opened the structure groove respectively, and the two ends of rubber distinguish in the embedded structure groove, thereby can improve the pressure of crossover position when formed product, the raising bind strength; Electric current was to the influence of metal-rubber bonding interface when this structure can largely be alleviated bethanizing, guaranteed adhesive effect and intensity after zinc-plated, the safety when having improved the rolling stock operation and the reliability of product design supportability.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1 ~ 2, a kind of used for rolling stock flexibly connects rubber arthrosis, comprise overcoat 1, rubber 2 and mandrel 3, mandrel 3 two ends have the through hole 5 that is used to connect the Vehicular vibration source, rubber 2 be enclosed within mandrel 3 middle parts and with mandrel 3 bonding connections, overcoat 1 be enclosed within on the rubber 2 and with rubber 2 bonding connections, overcoat 1 has been opened structure groove 4 with the bonding part and the mandrel 3 at rubber 2 two ends respectively with the bonding part at rubber 2 two ends, and in the two ends of the rubber 2 difference embedded structure groove 4.
The cross-sectional plane of structure groove 4 is a circular arc.After adopting the structure groove 4 of circular arc, electric current by the time can avoid producing the situation of adhesive failure by actv. owing to the point discharge reason causes the bonding interface of the excessive metal-rubber that causes of local current.
Principle of work of the present utility model is as follows: according to the profile design of product rubber part, in the combine reference position of metal with rubber, increase arc-shaped structure groove 4 respectively on overcoat and mandrel, the status requirement of structure groove 4 is the center in adhesive spots, innner and outer each half.Main is intended in the sulfidization molding process, and rubber flows to structure groove 4 places, forms the structure of a seal ring in groove, and actv. improves the pressure of junction, guarantees adhesive effect.In the process of bethanizing, increase the rubber layer of transition position, make under the electric current of rubber when bethanizing, rubber remains intact state, satisfies the adhesive property requirement.
Claims (2)
1. a used for rolling stock flexibly connects rubber arthrosis, comprise overcoat (1), rubber (2) and mandrel (3), mandrel (3) two ends have the through hole (5) that is used to connect the Vehicular vibration source, rubber (2) be enclosed within mandrel (3) middle part and with mandrel (3) bonding connection, overcoat (1) be enclosed within that rubber (2) is gone up and with rubber (2) bonding connection, it is characterized in that: overcoat (1) has been opened structure groove (4) with the bonding part and the mandrel (3) at rubber (2) two ends respectively with the bonding part at rubber (2) two ends, and in the two ends of rubber (2) the difference embedded structure grooves (4).
2. used for rolling stock according to claim 1 flexibly connects rubber arthrosis, it is characterized in that: the cross-sectional plane of described structure groove (4) is a circular arc.
