Abstract
The invention relates to the technical field of a rail wagon, in particular to a light braking lever. The light braking lever comprises a lever body and three lining sleeves. Two ends and the middle portion of the lever body are respectively provided with one lining sleeve. A weight reducing groove is formed in the lever body. The light braking lever can reduce the weight of the braking lever, decrease relief resistance after the wagon is braked and improve safety for wagon operation.
Description
Technical field
The application relates to the rolling stock technical field, particularly a kind of lightweight brake lever.
Background technology
The railway truck foundation brake rigging relies on the brake beam deadweight to alleviate, and it is less that it alleviates recuperability, and railway wagon brake lever weight lays particular stress on and further strengthened the alleviation resistance, affects the normal alleviation after car brakeing.The weight of existing railway wagon brake lever is larger, is unfavorable for the normal alleviation after car brakeing, and after car brakeing, improper release will jeopardize vehicle operating safety.On the other hand, sleet ponding easily occurs on existing railway wagon brake lever, accelerated the corrosion to the railway wagon brake lever, reduced the service life of railway wagon brake lever.
Summary of the invention
The application's technical matters to be solved is to provide and a kind ofly can alleviates brake lever weight, reduces alleviation resistance after car brakeing with the lightweight brake lever of the safety that improves vehicle operating.
For solving the problems of the technologies described above, the application provides a kind of lightweight brake lever, comprises lever body and three linings, and the two ends of described lever body and centre are respectively arranged with a lining.The two ends of described lever body are concordant, and the thickness at two ends is identical.Be provided with the loss of weight groove on described lever body.
Further, offer drain gutter in the described loss of weight groove on described lever body.
Further, the upper and lower faces of described lever body all offers described loss of weight groove.Described loss of weight groove on described lever body upper and lower faces is over against setting.Offer at least one drain gutter on described lever body upper and lower faces between the described loss of weight groove that arranges.
Further, on described lever body above and below, the degree of depth over against the described loss of weight groove that arranges is 5mm.
Further, the method setting of described loss of weight groove by forging on described lever body.
The lightweight brake lever that the application provides is provided with the loss of weight groove at the two ends of lever, has reduced the weight of brake lever, thereby has reduced the alleviation resistance after the car brakeing, has improved the safety of vehicle operating.Offer drain gutter in the loss of weight groove of lever body, can prevent from producing on brake lever sleet ponding brake lever is corroded, extended the service life of brake lever.
Description of drawings
The lightweight brake lever front view that Fig. 1 provides for the embodiment of the present application.
The lightweight brake lever longitudinal sectional view that Fig. 2 provides for the embodiment of the present application.
The specific embodiment
Referring to Fig. 1-Fig. 2, a kind of lightweight brake lever that the embodiment of the present application provides comprises lever body 1 and three linings 4.The two ends of lever body 1 and centre are respectively arranged with a lining 4.The two ends of lever body 1 are respectively arranged with loss of weight groove 2, are specially: the upper and lower faces of lever body 1 is respectively arranged with loss of weight groove 2, and the loss of weight groove 2 of lever body 1 upper and lower faces is over against setting.The method setting of loss of weight groove 2 on lever body 1 by forging.Offer drain gutter in loss of weight groove 2 on lever body 1, be specially: lever body 1 upper and lower faces offers 2 over against offering at least one drain gutter 3(the embodiment of the present application between the loss of weight groove 2 that arranges).Lever body 1 upper and lower faces is 5mm over against the degree of depth of the loss of weight groove 2 that arranges, and the thickness between lever body 1 upper and lower faces loss of weight groove 2 neighboring areas is 25mm.The two ends of lever body 1 are concordant, and the thickness at two ends identical (in the embodiment of the present application, the thickness at regulations and parameters body 1 two ends is 25mm).
The principle of work of the embodiment of the present application is as follows: be provided with loss of weight groove 2 on lever body 1, the peripheral thickness of loss of weight groove 2 identical with existing railway wagon brake lever (being all 25mm), alleviated brake lever weight under the prerequisite that guarantees the brake lever normal operation, reduce vehicle and alleviate resistance, make the vehicle can safe operation.Offer drain gutter 3 in loss of weight groove 2 on lever body 1, can discharge the sleet ponding in loss of weight groove 2 on lever body 1, make brake lever exempt from erosion.
The embodiment of the present application has following beneficial effect:
1, be provided with the loss of weight groove at the two ends of lever, reduced the weight of brake lever, thereby reduced the alleviation resistance after the car brakeing, improved the vehicle mitigation performance, reduced the wheel flat risk.
2, offer drain gutter in the loss of weight groove of lever body, can prevent from producing on brake lever sleet ponding brake lever is corroded, extended the service life of brake lever.
3, simple in structure, easy to assembly, the inspection to assembling rightness after being convenient to assemble is confirmed.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical scheme that the application is described, although with reference to example, the application is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the application's technical scheme, and not breaking away from the spirit and scope of present techniques scheme, it all should be encompassed in the middle of the application's claim scope.
