Embodiment 1

[0035] The embodiment of the present application provides a running device 1, such as figure 1 and figure 2 As shown in the structure, the running device 1 includes:

[0036] Vehicle frame 11, the central position of vehicle frame 11 tops is equipped with column 111, and the bottom of vehicle frame 11 is equipped with carriage hanger 18, and at least a part of carriage suspension 18 protrudes from the bottom of vehicle frame 11, and protruding part is used for hoisting micro The compartment of the rail vehicle; in order to reduce the weight of the running device 1 while not reducing the structural strength and rigidity of the vehicle frame 11, the vehicle frame 11 can be made of an aluminum alloy material;

[0037] Four drive wheels 12, four drive wheels 12 are symmetrically installed on both sides of vehicle frame 11; figure 1 As shown in the structure, one side of the vehicle frame 11 is provided with two driving wheels 12 arranged in front and rear, and the other side of...

Embodiment 2

[0059] The embodiment of the present application provides a micro-rail vehicle. The micro-rail vehicle includes a carriage and any running device 1 provided in the above embodiments. The carriage is hoisted at the bottom of the suspension 18 of the carriage.

[0060] The specific work process of the micro-track vehicle that adopts the above-mentioned running device 1 is as follows:

[0061] The start-up process control of the micro-rail vehicle: the control unit 22 judges the start-up condition of the micro-rail vehicle according to various signals collected, and transmits the start-up speed regulation instruction signal to the wheel hub motor drivers 131 of the four wheel hub motors 13, through which the wheel hub motor drivers 131 controls the operation of each hub motor 13 . The Hall sensor 132 located in the hub motor 13 detects the running state of the hub motor 13 in real time and outputs it to the hub motor driver 131. 131 feeds back the current, rotational speed, and ...

Abstract

The embodiment of the application relates to the technical field of rail vehicles, in particular to a micro-rail vehicle and a walking device thereof. The walking device comprises a frame, four driving wheels, four hub motors, a steering motor, four pairs of guide wheels, a carriage hanger, a brake motor, a current collecting device and a control unit. The hub motors are in one-to-one correspondence with the driving wheels and are used for driving the driving wheels to rotate; the steering motor is installed on one side of a stand column, is in transmission connection with two steering stabilizing wheels through a transmission mechanism and is used for driving the two steering stabilizing wheels to move in the vertical direction; the brake motor is used for driving a brake pad mounted on the frame to brake the driving wheels; the current collecting device is used for providing electric energy for the hub motors, the brake motor and the control unit; the control unit is used for controlling starting and stopping of the hub motors, the brake motor and the steering motor. According to the walking device, four-wheel independent driving can be achieved through the driving wheels and thehub motors which are in one-to-one correspondence, and two-way driving can be achieved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a micro-rail vehicle and its running device. Background technique [0002] Micro-rail vehicle is a new transportation mode with small capacity, point-to-point, customized, fully automatic and unmanned. The running device of the micro-rail vehicle runs inside or above the track beam. However, current microrail vehicles can only travel in one direction. Contents of the invention [0003] The embodiment of the present application provides a micro-rail vehicle and its running device. The running device can realize four-wheel independent driving through one-to-one corresponding driving wheels and hub motors. Therefore, the running device can realize two-way driving. [0004] According to the first aspect of the embodiments of the present application, a running device is provided, including: [0005] A vehicle frame, a column is installed at the center of the top o...
