Problems solved by technology
[0002] At present, with the development of science and technology, the speed of trains is getting faster and faster. However, when encountering bad weather or a railway curve in a dangerous area, if the train speed is too fast, there will still be a danger of overturning. The general risk avoidance operation It is manual operation. When the train driver receives the signal of the curve ahead, he will manually brake to slow down the speed of the train. This method still has risks. If the driver does not pay attention and brakes too late, there will be risks. In addition , when the train brakes in an emergency, ordinary brakes are difficult to completely stop the train in a short time, and it is necessary to place auxiliary pallets on the railway to lock the wheels to stop the train in a short time

Embodiment Construction
[0020] Combine below Figure 1-7 The present invention is described in detail, and for convenience of description, the orientations mentioned below are now stipulated as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0021] refer to Figure 1-7 According to an embodiment of the present invention, a railway train brake that can automatically decelerate on a curve includes auxiliary wheels 26, brake pads 32 and clamping plates 44, and two auxiliary wheels 26 are symmetrically arranged on the left and right, and are fixed on On the left and right sides of the track wheel 27, the train 11 is provided with a brake chamber 20 with an opening to the right, and the track wheel 27 abuts against the top surface of the rail 28, and the auxiliary wheel 26 is provided with a brake cavity that opens to the side away from each other. A deceleration chamber 25, the deceleration chamber 25 is provided with an arc-s...

The invention discloses a railway train brake capable of automatically decelerating at a curve. The railway train brake comprises auxiliary wheels, a brake pad and a clamping plate, wherein the two auxiliary wheels are arranged in a bilateral symmetry mode and are fixedly arranged on left and right side surfaces of a rail wheel; a brake cavity with a rightward opening is formed in the train; the rail wheel abuts against the top face of a steel rail; the auxiliary wheels are internally provided with speed reduction cavities which are opened towards the sides away from each other; an arc-shapedplate and a speed reducing ring are arranged in each speed reduction cavity; the arc-shaped plate is in contact with the speed reducing ring, so that the rotating speed of the rail wheel can be reduced. According to the invention, the safety accident problems such as rollover and the like caused by over-high speed can be effectively reduced when a train turns at a railway curve, the train can automatically sense the railway curve and decelerate, the problems of inattention and the like caused by manual operation are reduced, and meanwhile, a hydraulic brake system and an emergency brake deviceare also arranged.
Description
technical field [0001] The invention relates to the technical field of train brakes, in particular to a railway train brake that can automatically decelerate on curves. Background technique [0002] At present, with the development of science and technology, the speed of trains is getting faster and faster. However, when encountering bad weather or a railway curve in a dangerous area, if the train speed is too fast, there will still be a danger of overturning. The general risk avoidance operation Manual operation is adopted. When the train driver receives the signal of the curve ahead, he will manually brake to slow down the speed of the train. This method still has risks. If the driver does not pay attention and brakes too late, there will be risks. In addition , When the train is braking in an emergency, it is difficult to stop the train completely in a short time with ordinary brakes. It is necessary to place an auxiliary pallet on the railway to block the wheels so that ...
