Abstract
A sectional type brake shoe for railway vehicles comprises an arc-shaped cuboid structure. The tread of the sectional type brake shoe comprises four to eighteen pieces of arc-shaped block bodies which are arranged in two to six rows in the circumferential direction and two to three lines in the cross direction, and the space between any two arc-shaped block bodies is 2 mm to 4 mm. The technical progress and the outstanding features of the utility model embody in that the sectional type brake shoe has a wide range of application, can be applicable to vehicles adopting tread braking and disc braking such as the rolling stock, the motor train unit, the urban railway vehicle and the like, and can effectively reduce the abrasiveness of the braking part; and as the sectional type brake shoe is divided into a plurality of block bodies, the original thermal stress centralized on two sides of the brake shoe can be dispersed, and the removal of grindings is facilitated, so as to reduce the abrasiveness of the grooves of tire treads or brake discs, and prolong the service lives of wheels or the brake discs.
Description
Technical field
The utility model belongs to the rail vehicle technical field, relates in particular to the rail vehicle brake block.
Background technique
The braking of rail vehicle produces frictional force by brake shoe with contacting of wheel tread or brake disc and realizes.For a long time, the structure of brake block and even shape adopt traditional mode always, i.e. a kind of rectangular structure of arc.The deficiency of traditional braking brake shoe is: along with the raising of rail vehicles, city railway vehicle motion speed, the braking tread will bear bigger braking force, especially city rail vehicle is because frequent braking causes the serious groove abrasion of wheel tread, this has not only increased operation cost, has also influenced the Security and the stationarity of train operation.
Summary of the invention
The purpose of this utility model is a kind of brake block that can slow down the braking tread wear effectively of design.
The technical solution of the utility model is: a kind of used for rail vehicle sectional brake shoe, rectangular structure by arc constitutes, the braking tread that it is characterized in that described sectional brake shoe is made up of 4-18 piece arc block, it is capable that the arc block is arranged 2-6 at the circumferencial direction of brake shoe, laterally 2-3 is listed as, spacing 2-4mm between the arc block.
A kind of used for rail vehicle sectional brake shoe described in the utility model is characterized in that described arc block is by constituting at the circumferencial direction of the braking tread upper edge of whole brake shoe arc and the groove of laterally opening 2-4mm.
Technological progress of the present utility model and outstanding feature are: have wide range of applications, rolling stock, rail motor set, city railway vehicle etc. all adopt the vehicle of tread brake and disc brake to use, and can effectively alleviate the abrasion at braking position; Brake shoe is divided into several blocks, in braking process, can disperses to concentrate on originally the thermal stress of brake shoe both sides, and help the eliminating of abrasive dust, thereby reach the groove abrasion that alleviate wheel tread or brake disc, prolong the working life of wheel or brake disc.
Description of drawings
The utility model has 4 width of cloth accompanying drawings, wherein,
Fig. 1: traditional braking brake shoe shape schematic representation
Fig. 2: two row four lines wheel tread brake block schematic representation of the present utility model
Fig. 3: three row four lines wheel tread brake block schematic representation of the present utility model
Fig. 4: three row, six row disc brake brake shoe schematic representation of the present utility model
In the accompanying drawing, 1, the arc block, 2, spacing between the arc block.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 2 and Fig. 3 are the forms of blocking type wheel tread brake block, Fig. 2 is the wheel tread brake block of two row four lines, be that the braking tread of former whole brake shoe is along the circumferential direction being offered the groove of one 4mm, laterally offer the sectional brake shoe that the groove of three road 4mm constitutes with eight blocks 1.Fig. 3 is the wheel tread brake block of three row four lines, is the braking tread of former whole brake shoe is along the circumferential direction being offered the groove of two road 4mm, laterally offers the sectional brake shoe with 12 blocks 1 that the groove of three road 4mm constitutes.The manufacture method of the wheel tread brake block of Fig. 2 and Fig. 3 is the design by Fig. 2 and Fig. 3, leaves 4mm spacing 2 between block, the casting processing moulding.
Fig. 4 blocking type disc brake brake shoe by the groove of along the circumferential direction offering two road 4mm, is laterally offered the sectional brake shoe with 18 blocks 1 of the groove formation of five road 4mm.
Claims (2)
1. used for rail vehicle sectional brake shoe, rectangular structure by arc constitutes, and it is characterized in that the braking tread of described sectional brake shoe is made up of 4--18 piece arc block, and it is capable that the arc block is arranged 2-6 at the circumferencial direction of brake shoe, laterally 2-3 is listed as, and spacing 2 is to 4mm between the arc block.
2. a kind of used for rail vehicle sectional brake shoe according to claim 1 is characterized in that described arc block is by constituting at the circumferencial direction of the braking tread upper edge of whole brake shoe arc and the groove of laterally opening 2-4mm.
