Abstract
A bimetal fusion cast 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 side surface. The utility model is characterized in that multiple metal friction blocks are embedded at the same side of a cast steel base body, the metal friction blocks and the cast steel base body are fused into a whole, and a wheel guide slope is provided at both ends of the brake plate. Owning to fusion integration of the friction blocks and the cast steel base body, the friction blocks have reliable fixation. By using the high performance friction blocks, the brake plate has friction coefficient of 0.3-0.45 to the wheel, which has good brake effect 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 drag friction 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 composite metal founding friction braking plate, and it is big to the friction coefficient of wheel, good braking effect.
The technical solution of the utility model is: this kind composite metal founding friction braking plate, it is characterized in that, a plurality of metal friction pieces are embedded in the same side of cast steel substrate, and metal friction piece and cast steel substrate welding are one, are provided with the wheel lead-in chamfered at the slipper two ends.
The cross section of cast steel substrate can be I shape, square or rectangle.
The beneficial effects of the utility model are:
This slipper since friction shoe by inblock cast in cast steel substrate, friction shoe and cast steel substrate welding are also held tightly and are one, thereby friction shoe is fixing reliable, after using performance-oriented friction shoe, slipper can reach 0.3-0.45 to the friction coefficient of wheel, good braking effect, 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.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the birds-eye view of Fig. 1;
Among the figure: 1 cast steel substrate, 2 friction shoes, 3 welding areas, 4 lead-in chamfered.
The specific embodiment
As Fig. 1, Fig. 2.This kind composite metal founding friction braking plate, its basic structure be, a plurality of metal friction pieces 2 are positioned at the same side of cast steel substrate 1, and the appearance of metal friction piece 2 and cast steel substrate welding are one.Be provided with wheel lead-in chamfered 4 at the slipper two ends.
During making, with slipper modelling casting sand type, built-in metal friction shoe 2 in sand mold, the metal friction block gap is suitable.During the casting molten steel, cast steel substrate 1 welding after metal friction piece 2 surface meltings and the casting is an one, and welding thickness is suitable, and after the foundry goods cooling, cast steel substrate and friction shoe are held tightly, forms composite metal founding friction braking plate blank.This blank is through heat treatment, straightening and be machined to and be the slipper finished product.
The cross section of cast steel substrate can be I shape, square or rectangle etc.
