Problems solved by technology

This structural method is simple and reliable, but its shortcoming is that in addition to ensuring the structural requirements necessary for the installation of the brake, the length of the suspension screw rod also needs to reserve sufficient margin for adjustment at the end, which will cause suspension structure Overall size is larger
On the other hand, if the installation space limits the overall size of the suspension, the amount of adjustment is difficult to guarantee

Embodiment Construction

[0028] The specific implementation of the electromagnetic track brake suspension device for rail transit vehicles of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] See attached figure 1 The light rail vehicle electromagnetic track brake suspension device includes set screw 1, spring upper base 2, suspension spring 3, spring lower base 4, elastic pin 5, locking wedge 6, gaskets 7, 8, suspension screw sleeve 9, anti Dust cover 10, suspension tray 11, spherical gasket 12, adjusting screw rod 13, locking bolt 14 and elastic circlip 15.

[0030] The set screw 1 is used as an optional part, and is embedded in the spring upper base 2 and the suspension screw sleeve 9 to connect the thread joint, so as to prevent the nut from loosening.

[0031] The flange surface of the base 2 on the spring is pressed on the suspension spring 3, and the lower end of the suspension spring is supported by the base 4 under the spring. Th...

Abstract

The invention relates to the technical field of electromagnetic track brakes of track vehicles and discloses a suspension device for an electromagnetic track brake of a track traffic vehicle. An upper spring base and a lower spring base are arranged on a suspension screw sleeve; a suspension spring is mounted between the upper spring base and the lower spring base; a threaded hole in the middle of the suspension screw sleeve is matched with the upper end of an adjusting screw; a lower boss is arranged at the lower end of the adjusting screw; a suspension tray is movably arranged on the lower boss; a through hole is formed in the middle of the adjusting screw; the upper end of the through hole takes the shape of a horn mouth; a locking bolt is arranged in the through hole; the upper end of the locking bolt penetrates through the horn mouth; the upper end of the locking bolt is connected with a locking wedge through threads; the locking wedge is matched with the horn mouth; a flange surface of the lower spring base, a shaft shoulder of the suspension screw sleeve and the vehicle are fixedly mounted; the suspension tray and the brake are fixedly mounted. An existing lead screw nut structure is replaced, the structure is compact, and the overall length is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electromagnetic track brakes for rail vehicles, in particular to a suspension device for electromagnetic track brakes for rail vehicles. Background technique [0002] The electromagnetic track brake of the low-floor light rail vehicle is installed by a suspension device, which is mainly composed of a suspension screw rod, a suspension spring, a spring seat, and a suspension tray. The suspension device must not only have the function of supporting the electromagnetic track brake, but also need to have the function of adjusting the distance between the brake and the track surface, so that the distance can be kept within the normal use requirements when the wheels or brake friction parts are worn. The structural method generally adopted in the current suspension device is to change the distance between the brake and the frame support by adjusting the position of the support nut of the suspension tray or spri...
