Problems solved by technology

[0003] Under normal circumstances, the train brake adopts a single braking method, which has potential safety hazards caused by brake failure. Usually, the hydraulic contact type is also used. This method has a good braking effect, but the potential safety hazards increase with the use of time. Other braking methods include sand braking. Sand braking is safer, but the demand for sand is also large. Therefore, a train brake installed at the bottom of the train is needed to solve the above problems

Embodiment Construction

[0017] Combine below Figure 1-4 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The front, back, left, right, up, and down directions of the view direction are the same, figure 1 It is the front view of the device of the present invention, figure 1 The directions shown are consistent with the front, back, left, right, up, and down directions of the front view direction of the device of the present invention.

[0018] refer to Figure 1-4 According to an embodiment of the present invention, a train brake installed at the bottom of a train includes a vehicle body 20, and a wheel space 44 with an opening downward is arranged symmetrically front and rear in the vehicle body 20, and the wheel space 44 is provided with a friction active brake. A friction member 80 for shaft braking, the friction member 80 includes four wheel axles 59 rotatably mounted between the front wa...

Abstract

The invention discloses a train brake mounted at the bottom of a train. The train brake includes a vehicle body, wherein a frosted block can be in contact with a first wheel axle on the left side; a push rod drives a fixed rod, the push rod and a push plate to move rightwards to push sand in the sand storage space into a sand outlet channel to fall on the ground, thus changing the conventional one-time sand paving braking condition; the sand used for paving the sand can be immediately recycled after being used up; and secondary sand paving is prepared, so that the demanded quantity of sand isreduced, and the weight of a train body is reduced, and the cost is saved, and the situation of single braking is changed, and main contact braking and secondary sand paving braking are combined, andthe braking effect is enhanced, and the train running safety is improved, and a power source is from mechanical energy generated by rotation of train running wheels, and energy consumption is greatlyreduced.

Description

technical field [0001] The invention relates to the field of special brakes or other deceleration devices for railway vehicles, in particular to a train brake installed at the bottom of the train. Background technique [0002] Brake, commonly known as "brake", is the action of stopping or reducing the speed of running locomotives, vehicles and other means of transportation or machinery, etc. [0003] Under normal circumstances, the train brake adopts a single braking method, which has potential safety hazards caused by brake failure. Usually, the hydraulic contact type is also used. This method has a good braking effect, but the potential safety hazards increase with the use of time. Other braking methods also include sand-spray braking, which is safer, but also requires a lot of sand. Therefore, a train brake installed at the bottom of the train is needed to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a t...
