Abstract
A cast steel frame embedded-type friction brake plate belongs to a special brake equipment of a retarder, a parking device, a speed reducer, and other railroad vehicle anti-running devices for regulating speed of coasting trains by automatic hump of marshalling yard, which mainly solves issues of friction force between a brake component and a wheel. The utility model is characterized in that the cast steel frame has a groove at the brake face thereof; a friction block or material compressed or sintered into block form is fixed in the groove of the cast steel frame. The brake plate is provided with wheel guide blocks at both ends thereof. Owning to the embedded high performance friction block, the friction coefficient to the wheel can reach 0.3-0.45 to achieve good brake performance, desirable overall strength, and reduced mechanical noise. The utility model can be used in a retarder, a parking device, a speed reducer, and other railroad vehicle anti-running devices for regulating speed of coasting trains by automatic hump of marshalling yard.
Description
Technical field
The utility model relates to a kind of special-purpose friction braking plate that is used for the automation of railway yard hump to the anti-slide of retarder, stopping device, retarder and other rolling stocks device of skating vehicle speed governing.
Background technology
At present the clamp type and the anti-device that slips of inner bearing type retarder, stopping device and the braking of other similar vehicles that use of automation of railway yard hump all uses rail as braking element (claiming friction plate or braking rail), little, the friction braking weak effect of friction coefficient of itself and wheel.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model provides a kind of cast steel framework inserted friction braking plate, and it is big to the friction coefficient of wheel, good braking effect.
The technical solution of the utility model is: the inserted friction braking plate of this kind cast steel framework, it is characterized in that, the cast steel framework is positioned at brake surface one side and is provided with groove, and friction material is fixed in the cast steel frame groove with the form of boxed area, and the slipper two ends are provided with the wheel bootstrap block.
Further program of the utility model is:
Aforementioned friction material is meant with the form of boxed area: friction material is fixed in the cast steel frame groove with the friction shoe form.
When adopting pre-formed friction shoe, can adopt friction material one of any in high-phosphorous iron, partial metallurgy, semi-metallic, the non-metallic material to make friction shoe.
The fixed form of friction shoe adopt comprise welding, riveted joint, bolted or be adhesively fixed in any or two or more combination fixed forms.
Aforementioned friction material can also be meant with the form of boxed area: the powder high-temperature high-pressure of friction material pack in the cast steel frame groove or the powder High Temperature High Pressure sintering of friction material in the cast steel frame groove, press-fit with the cast steel framework and to be integral.
In the case, described friction material adopts friction material one of any in metal, semimetal and the non-metallic material to make.
The slipper groove adopts gridiron structure: in promptly the powder high-temperature high-pressure of friction material was packed the sash of cast steel frame groove into, the segmentation in groove of described sash was provided with dividing plate and forms.
Further scheme is, is provided with in the bottom of cast steel frame groove to press-fit or the sintering reinforced hole.
Aforementioned cast steel framework transversal surface is I-shape or rectangle.
The cross section of aforementioned cast steel frame groove is rectangle or dovetail form.
The beneficial effects of the utility model are: the cast steel framework is inlayed high-quality friction material, makes slipper can reach 0.3-0.45 to the friction coefficient of wheel, good braking effect, and bulk strength satisfies operating needs, also can reduce mechanical noise.Compare with the scheme of the slipper that uses rail to do, equal braking deceleration effect can reduce brake-pressure, reduces effective friction braking length, significantly improves the Combination property of retarder, stopping device, the similar rolling stock parking anti-slip with other of retarder device.
