Abstract
The utility model discloses a railway wagon brake shoe holder with low running resistance. The railway wagon brake shoe holder comprises a shoe holder body, wherein at least two rolling shafts are arranged on the shoe holder body; and rollers capable of matching with a side frame slide groove are mounted on the rolling shafts. The railway wagon brake shoe holder disclosed by the utility model has the advantages of simple structure and low running resistance. By using a double-roller structure, the rotation of the brake shoe holder is limited, the brake shoe can be guaranteed to completely leave away from the wheel when the braking device is relieved, and local wear is avoided; and by using a roller structure, the relative motion of the brake shoe holder body and the side frame slide groove is converted into rolling motion so that the running resistance of the brake shoe holder is effectively reduced.
Description
Technical field
The utility model relates to the railway goods train bogie brake equipment, relates in particular to a kind of low running resistance railway truck brake head, belongs to railway truck braking technology field.
Background technology
Foundation brake rigging is the important component part of railway goods train bogie.Brake equipment braking, alleviate whether flexibly, significant effects is arranged for the deceleration and stopping performance of railway truck.And the braking of brake equipment and alleviation all will realize through brake head moving forward and backward in the bogie side frame chute.
At present, the railway truck brake head has two kinds of forms, and a kind of is roller type, and a kind of is slide block type.
Roller type brake head end is Roller Shaft+roller structure, can in the bogie side frame chute, freely roll, and running resistance is little, and release of brake is flexible.But because the effect of gravity, brake head can rotate around roller centre, and when brake equipment was alleviated, the brake shoe top of installing on the brake head still rode on the wheel, causes alleviation bad, causes local abrasion, the service life of reducing wheel and brake shoe.
The end of slide block type brake head is slide block+abrasion nested structure.Slide block is generally rectangle or quadrangle with the abrasion cover, because the gap of slide block abrasion cover and bogie side frame chute is less, the rotation of brake head is restricted, and when brake equipment was alleviated, brake shoe was difficult for taking place local contact wheel phenomenon.But, in practice,, cause force of sliding friction big because the effect of gravity and braking force causes slide block to wear and tear the additional contact force of cover and chute, when brake equipment was alleviated, the recoil movement of brake head was not dumb, generally caused alleviation bad.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, provide a kind of simple in structure, running resistance is low, alleviate good low running resistance railway truck brake head.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of low running resistance railway truck brake head, it comprises a watt base body, a watt base body is provided with at least two Roller Shaft, and the roller that can match with the bogie side frame chute is installed on the Roller Shaft.
Said Roller Shaft is two, and said roller is two.
Roller Shaft casting or forging are on brake head, and roller is installed on the Roller Shaft.
When action is braked, alleviated to brake equipment, this brake head can pass through two rollers, is the rolling of roller with the forward-reverse conversion of motion of brake head in the bogie side frame chute.Change the cliding friction of brake head and chute relative motion into friction of rolling, reduce running resistance, realize the flexible of braking, alleviation.
Compared with prior art, the utlity model has following advantage:
1. the utility model is through two roller structures, is the rolling of roller with the forward-reverse conversion of motion of brake head, and running resistance is low, and effect flexibly.
2. the utility model has solved traditional single roller brake head and can't limit the brake head rotational angle, and the local contact of brake shoe wheel causes and alleviates the bad problem serious with abrasion when causing alleviating.The utility model can limit the rotational angle of brake head, thoroughly the separating of brake shoe and wheel when realize alleviating, avoids local abrasion.
3. the utility model has solved traditional slide block type brake head because the ubiquity that additional contact force causes force of sliding friction to increase initiation is alleviated bad problem.
4. the utility model is simple in structure, production is easy to maintenance, and use cost is low.
Description of drawings
Fig. 1 is the structural representation and the fundamental diagram of the low running resistance railway truck brake head of the utility model.
Fig. 2 is a birds-eye view of having simplified Fig. 1 of wheel and brake shoe.
Among the figure: 1, watt base body, 2, Roller Shaft, 3, roller, 4, the bogie side frame chute, 5, brake shoe, 6, wheel.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As depicted in figs. 1 and 2, the low running resistance railway truck brake head of the utility model comprises 1 watt of base body 1, two Roller Shaft 2, two rollers 3.Roller Shaft 2 castings or forging are on watt base body 1; Roller 3 is installed on the Roller Shaft 2, and can rotate around Roller Shaft 2.
After adopting above-mentioned technology, when action is braked, alleviated to brake equipment, this brake head can pass through two rollers 3, is the rolling of roller 3 with the forward-reverse conversion of motion of brake head in bogie side frame chute 4.Because the utility model has adopted two roller structures, when brake head rotated, two rollers 3 blocked the upper and lower surfaces of bogie side frame chute 4 respectively, and the rotational angle of restriction brake head prevents that the brake shoe of installing on the brake head 5 from wheel 6 local the contact being taken place; Simultaneously,, when they increase with the additional contact force of bogie side frame chute 4, can not cause the incident sliding resistance of existing slide block structure to increase phenomenon, guarantee to alleviate flexible because two rollers 3 are rolling structure.
The utility model is simple in structure, running resistance is low.Through two roller structures, limited the rotation of brake head self, brake shoe 5 can leave wheel 6 fully when guaranteeing the brake equipment alleviation, avoids local abrasion; Roller structure changes the relative motion of brake shoe base body 1 and bogie side frame chute 4 into rolling movement, effectively reduces the running resistance of brake head.
Claims (2)
1. one kind low running resistance railway truck brake head, it comprises a watt base body, it is characterized in that, a watt base body is provided with at least two Roller Shaft, and the roller that can match with the bogie side frame chute is installed on the Roller Shaft.
2. a kind of low running resistance railway truck brake head according to claim 1 is characterized in that said Roller Shaft is two, and said roller is two.
