技术领域Technical Field
本发明涉及轨道交通车辆技术领域，尤其涉及一种齿轨车驱动***的制动结构及齿轨车。The present invention relates to the technical field of rail transit vehicles, and in particular to a braking structure of a rack rail vehicle driving system and a rack rail vehicle.
背景技术Background technique
目前，齿轨车作为国内新兴的轨道交通方式，仅仅在个别旅游景区有少量应用，各***技术均在研发完善阶段。由于齿轮和齿条传动的特点，齿轮和齿条啮合具有较严格的中心距要求，而车轮随着使用会逐渐磨损，使得齿轨轮与齿条的啮合高度会随之改变。齿轨车驱动***作为齿轨车核心部件，随着车轮磨损各***高度如何适应则成为需要解决的关键问题。At present, rack-and-pinion vehicles, as a new type of rail transportation in China, are only used in a few tourist attractions, and the technology of each system is in the stage of research and development. Due to the characteristics of gear and rack transmission, the meshing of gear and rack has strict center distance requirements, and the wheels will gradually wear with use, causing the meshing height of the rack wheel and rack to change accordingly. As the core component of the rack-and-pinion vehicle, the rack-and-pinion vehicle drive system has become a key issue that needs to be solved as the wheels wear and the height of each system adapts.
现有技术中，在齿轨车驱动***中通常会设置偏心机构，偏心机构与齿轨轮连接。当车轮发生磨损后，能通过偏心机构对齿轨轮高度进行适应性调节，从而保障齿轨轮和齿条之间的稳定啮合。如CN109532888A、CN111762210A、CN110450811A中公开的结构，均能实现对齿轨轮高度的调节。In the prior art, an eccentric mechanism is usually provided in the rack vehicle driving system, and the eccentric mechanism is connected to the rack wheel. When the wheel is worn, the height of the rack wheel can be adaptively adjusted by the eccentric mechanism, thereby ensuring stable meshing between the rack wheel and the rack. For example, the structures disclosed in CN109532888A, CN111762210A, and CN110450811A can all achieve the adjustment of the height of the rack wheel.
然而，现有技术中，虽然能通过偏心机构实现对齿轨轮的高度进行调节。但在齿轨轮调节高度后，齿轨车驱动***中的制动机构与齿轨轮之间的相对位置也会发生改变，从而影响到制动机构对齿轨轮制动力的施加，影响制动机构的制动性能。However, in the prior art, although the height of the rack wheel can be adjusted by the eccentric mechanism, after the height of the rack wheel is adjusted, the relative position between the brake mechanism and the rack wheel in the rack vehicle driving system will also change, thereby affecting the application of the brake force of the brake mechanism on the rack wheel and affecting the braking performance of the brake mechanism.
发明内容Summary of the invention
针对现有技术中当齿轨轮进行高度调节后，齿轨轮与制动机构之间的相对位置会发生改变，影响制动机构的制动性能的技术问题。本发明提供了一种齿轨车驱动***的制动结构，其不仅可以解决随着车轮磨耗，影响齿轨轮和齿条的啮合问题；同时还可以解决齿轨轮高度调节后，制动机构的合适工作位置调整问题，可以更好的保障制动机构的制动性能。Aiming at the technical problem in the prior art that the relative position between the rack wheel and the brake mechanism will change after the rack wheel is adjusted in height, thus affecting the braking performance of the brake mechanism, the present invention provides a brake structure of a rack vehicle driving system, which can not only solve the problem of affecting the meshing of the rack wheel and the rack as the wheel wears, but also solve the problem of adjusting the appropriate working position of the brake mechanism after the rack wheel is adjusted in height, thereby better ensuring the braking performance of the brake mechanism.

The gearbox frame 20 and the eccentric mechanism 30 are mounted on the axle 10, and the rack wheel 40 is mounted on the eccentric mechanism 30. Thus, the position of the rack wheel 40 can be adjusted by the eccentric mechanism 30, and the eccentric mechanism 30 can adopt any adjustment mechanism in the prior art for adjusting the rack wheel 40, which is well known to those skilled in the art and is not a specific improvement point of this embodiment, and will not be repeated here.

The brake hub 51 is mounted on the rack wheel 40, and the brake belt 52 surrounds the brake hub 51. The output end of the driving device 53 is connected to the brake belt 52 to drive the brake belt 52 to tighten or loosen the brake hub 51. That is, in this embodiment, the brake mechanism 50 is a belt brake mechanism, which produces a braking effect on the rack wheel 40 by controlling the brake belt 52 surrounding the brake hub 51 to contract.
其中，在本实施例中，所述驱动装置53安装于所述齿轮箱框架20上。当然，在其他实施例中，所述驱动装置53也可安装于齿轨车的其他框架结构上，只需保障所述驱动装置53稳定安装即可。 In this embodiment, the driving device 53 is installed on the gear box frame 20. Of course, in other embodiments, the driving device 53 can also be installed on other frame structures of the rack vehicle, as long as the driving device 53 is stably installed.
所述调节机构60包括支架61、连接件62，所述支架61可转动安装于所述齿轮箱框架20，且所述支架61与所述驱动装置53的输出端连接。即所述支架61安装于所述齿轮箱框架20，且所述支架61能相对于所述齿轮箱框架20转动。所述连接件62分别与所述偏心机构30、所述支架61连接，以在所述偏心机构30转动调节时，带动所述支架61转动，以调节所述制动带52位置。即所述连接件62连接于所述偏心机构30与所述支架61之间，从而在所述偏心机构30对所述齿轨轮40进行转动调节时，所述偏心机构30会同步带动所述连接件62运动，使得所述连接件62会对所述支架61进行施力，带动所述支架61进行转动，最终由所述支架61的转动来调节所述制动带52的位置。也就是说，本实施例中通过设置所述调节机构60，让所述制动带52与所述偏心机构30产生联动，在所述偏心机构30调节所述齿轨轮40移动，从而带动所述制动毂51移动时，所述制动带52也会在所述调节机构60的带动下进行相应的移动，从而确保所述制动带52与所述制动毂51之间的相对位置关系，保障了所述制动带52对所述制动毂51的制动效果。The adjustment mechanism 60 includes a bracket 61 and a connecting member 62.
