Embodiment
[0035] Such as figure 1 , 2 As shown, a suspended monorail independent speed wheel device includes a fixed bracket 1, a swing bracket 2, a shaft bolt 3, a speed wheel shaft mechanism 4, a wheel disc 5, a speed wheel 6, a side bracket 7, a speed sensor 8 and a compression spring Mechanism 9; one longitudinal end of the swing bracket 2 is rotatably connected to the fixed bracket 1 through a horizontal and transverse shaft bolt 3, and the fixed bracket 1 partially extends above the swing bracket 2 and sets a vertical shaft between the extension part and the swing bracket 2. To the compression spring mechanism 9, the swing bracket 2 is also horizontally opened through the shaft holes on both sides, the speed measuring wheel shaft mechanism 4 is installed in the shaft hole, and the two ends of the speed measuring wheel shaft mechanism 4 are coaxially fixed and installed. Disc 5, side bracket 7 and speed sensor 8, said tachometer wheel 5 is mounted on the disc 5 and positioned cent...

The invention discloses a suspension type monorail independent speed measuring wheel device comprising a fixed support, a swing support, a shaft bolt, a speed measuring wheel shaft mechanism, a wheeldisc, a speed measuring wheel, a side support, a speed sensor and a pressure spring mechanism; the longitudinal end of the swing support is rotationally connected to the fixed support through a horizontal transverse shaft bolt, the fixed support partially extends to the upper portion of the swing support and the vertical pressure spring mechanism is arranged between the extension portion and the swing support, a shaft hole penetrating through the two sides is transversely formed in the swing support, the speed measuring wheel shaft mechanism is installed in the shaft hole, the wheel disc, theside support and the speed sensor are coaxially and fixedly installed at the two ends of the speed measuring wheel shaft mechanism, and the speed measuring wheel is installed on the wheel disc and ispositioned in the center. The suspension type monorail independent speed measuring wheel device in the invention can be installed at the front end or the rear end of a bogie, the arrangement and installation are not limited by internal space and structure of the bogie, the arrangement and installation of other systems and parts on the bogie are not affected, and the difficulty in arrangement and installation is solved.
Description
technical field [0001] The invention relates to a suspended monorail independent speed measuring wheel device, which belongs to the technical field of rail transportation. Background technique [0002] The main function of the urban rail vehicle speed measuring device is to measure and calculate the vehicle speed in real time. The speed sensor of the running part of the traditional vehicle is usually installed on the axle end of the bogie and fixed on the axle box, and the speed sensor is used to detect the speed of the running wheel to measure the speed of the vehicle; there are also speed sensors installed at the output end of the motor or at the gearbox, through the speed ratio conversion Get the running speed. [0003] These layout and installation methods have certain requirements for the internal layout space of the bogie, but in the suspended monorail vehicle, the structure of the bogie is usually very compact, and there is no space to arrange the speed sensor, so it...
