Embodiment Construction

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0039] Such as Figure 1 to Figure 7 As shown, the present invention relates to a micro-rail traffic vehicle braking device test bench, which is applied in the field of rail transit, especially in the test and monitoring process of the micro-rail braking device. The test bench includes a base 1, a driving device 2, a torque speed sensor 5 for collecting the braking torque and speed of the braking device to be tested, an inertia flywheel group 6 for adjusting the ratio of the test moment of inertia, and a Install the mounting flange 7 and the mounting bracket 8 of the brake device to be tested. Due to the reasonable design of the overall structure, the structure of the parts is small and the space occupied is small, ...

Abstract

The invention relates to a micro-rail traffic vehicle brake device testing stand and system. The testing stand comprises a pedestal, a driver, a torque and rotating speed sensor, an inertia flywheel group, an installation flange and an installation support. The testing system comprises the testing stand, a data collecting and processing system and a central control center. The testing stand is provided with a brake device to be tested, the central control enter controls the testing stand and brake device to implement brake test, and sends brake data to the data collecting and processing system, and the data collecting and processing data collects test and brake data of the testing stand and processes the data. According to the testing stand and system, not only performance of the brake device of a micro rail vehicle but also parts as a brake pad easy to wear can be tested, and the stand and system have great significance in guiding selection of the brake pad material and designing thebrake pad. The simulation performance is high, operation is easy, the service life is long, and the test precision is high.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a test bench and a test system for a brake device of a micro-rail transit vehicle. Background technique [0002] Micro-rail transportation is a new type of transportation with small volume, point-to-point, customization, fully automatic and unmanned driving, which can be used in tourist attractions and line branches. It has outstanding advantages in humanization, environment matching, construction period and cost. [0003] As the core component of the micro-rail transportation vehicle, the brake device is of qualified quality and excellent performance, which is an important guarantee for driving safety. First of all, the braking device needs to generate a large enough braking torque during the braking process; secondly, it requires good thermal stability and good wear resistance of the braking capacity. Due to the high cost, long time and poor safety of the actual loading test, in o...
