[0004] The purpose of the present invention is to overcome the need to provide a large rotational moment when the above-mentioned existing rotary permanent magnet track brake is braked or released, the requirements for the strength of the permanent magnet shaft are very high, and the rotation angle of the permanent magnet shaft is difficult to accurately control and brake. In order to avoid the disadvantages of different degrees of wear on the front and back of the boots, a permanent magnetic track brake with good braking effect and easy operation is provided; another object of the present invention is to provide a braking method for the permanent magnetic track brake

Embodiment Construction
[0019] Such as figure 1 As shown, the permanent magnetic track brake of the present invention is arranged directly above the track 18, and the permanent magnetic track brake includes n brake blocks 12, n-1 non-magnetic conductive partitions 13, and two non-magnetic conductive cover plates 14 And support 15; two installation fixtures 19 are installed above the support 15, and the two installation fixtures 19 fix the support 15 on the rail vehicle bogie along the length direction, so that the length direction of the support 15 is consistent with the longitudinal direction of the track 18. Between the support 15 and the track 18 are provided with n brake blocks 12 and n-1 non-magnetic partitions 13, and n brake blocks 12 and n-1 non-magnetic partitions 13 follow the track 18 in sequence The longitudinal intervals are closely arranged, and a non-magnetic partition 13 is arranged between every two brake blocks 12, and the non-magnetic partition 13 plays a buffering role in the brak...

The invention discloses a railway vehicle permanent magnetic rail brake and a braking method. The railway vehicle permanent magnetic rail brake comprises a plurality of braking blocks arranged along the longitudinal direction of a rail. Each single braking block comprises a permanent magnet magnetized along the horizontal direction on the transverse direction of the rail, two first iron blocks, two non-magnetic side covers and a moving shaft. An oil cavity is formed in one non-magnetic side cover at one side. A sealing chamber is formed by space among the oil cavity, two brake shoes and the permanent magnet. The horizontally moving shaft formed by two same second iron blocks, an aluminum board and two same pistons in connection is arranged in the sealing chamber. The moving shaft moves to the position where the two second iron blocks are respectively aligned to the two first iron blocks along the transverse direction, so that a magnetic loop is formed and braking is achieved. The moving shaft moves to the position where the piston at the right end is located in the oil cavity with the second iron blocks, so that the permanent magnet is under magnetic shielding and the braking is removed. The brake is divided into a plurality of sections. Abrasion degree of each brake shoe is nearly identical and braking performance is good. Due to adoption of arrangement method of linear movement, operation is easy and control is accurate.
Description
technical field [0001] The invention relates to a permanent magnet magnetic track brake of a rail vehicle, which realizes the braking or release of the railway train vehicle. Background technique [0002] Existing permanent magnetic track brakes are usually rotary type, which mainly include permanent magnet shaft, bracket structure, permanent magnet, brake shoe, switch control device; when the switch control device makes the permanent magnet shaft rotate an angle in the bracket, the A closed magnetic circuit is formed between the permanent magnet, the bracket, the brake shoe and the rail, and the sliding friction between the brake shoe and the rail produces a braking effect on the rail vehicle; when the switch control device makes the permanent magnet shaft rotate in the bracket for one Angle, a closed magnetic circuit is formed between the permanent magnet and the bracket, and the brake shoe has no suction effect on the rail, thereby realizing the release of the brake.
