Embodiment 2

[0031] On the basis of the first embodiment, the structure of the pneumatic control system 2 is further disclosed. The pneumatic control system 2 of this embodiment includes a parking brake control system 201 and a service brake control system 202 .

[0032] The parking brake control system 201 includes a parking booster pump 2011, a quick exhaust valve 2012, and a power source 2013. The power source 2013, the quick exhaust valve 2012, and the parking booster pump 2011 are In sequence, the parking booster pump 2011 is connected to the parking hydraulic brake pipeline 107 .

[0033] The service brake control system 202 includes a service booster pump 2021, a relay valve 2022, an air storage tank 2023, a relay valve controller 2024, and a power gas source. The power gas source, the gas storage tank 2023, and the relay valve 2022 , the driving booster pump 2021 is connected sequentially through a high-pressure air pipe, the relay valve controller 2024 is connected to the relay va...

Embodiment 3

[0036] On the basis of Embodiment 1 or Embodiment 2, the pneumatic control system 2 of this embodiment can control multiple wheels 102 of the axle 1. In this embodiment, the pneumatic control system 2 controls two The vehicle axle 102, the two vehicle axles 102 are provided with braking power by the same power air source 2013, forming a moving vehicle axle system.

[0037] The braking method of the disc-type traveling and parking integrated braking axle of the present invention includes parking braking and service braking, wherein:

[0038]When parking brake, cut off the power air source, the parking booster pump cannot provide the hydraulic power of the active hydraulic control pipeline, and the friction plate of the brake caliper clamps the brake disc under the action of the spring to realize the parking brake; When the parking brake needs to be released, connect the power air source, the parking booster pump provides the hydraulic power of the parking hydraulic control pipe...

Abstract

The invention relates to a disc type traveling and parking integrated brake axle. The brake axle comprises two axles, wheels rotationally arranged at the two ends of the axles, a longitudinal beam connected with the two axles, and a mounting base arranged on the longitudinal beam. A brake disc is arranged on a rim of each wheel, a brake caliper is arranged on each brake disc, and brake calipers are fixedly mounted on the axles through mounting plates; each brake caliper is connected with a pneumatic control system through a parking hydraulic braking pipeline and a service hydraulic braking pipeline, and service braking or parking braking of the brake calipers is controlled by the pneumatic control system. The braking structure is designed to be a disc type braking structure, the brake calipers are respectively braked by the parking hydraulic brake pipelines and the service hydraulic brake pipelines, the parking brake control system and the service brake control system are designed to respectively provide brake power for the parking hydraulic brake pipelines and the service hydraulic brake pipelines, and a pneumatic and hydraulic brake combined mode is adopted, so that the brake isreliable.

Description

technical field [0001] The invention relates to the technical field of moving axles, in particular to a disc-type traveling and parking integrated braking axle and a braking method thereof. Background technique [0002] The existing oilfield drilling rig platform overall transfer axle system either does not have a braking system, or only has a braking function, but no parking braking function, and its braking system generally uses a drum braking system. The braking capacity is insufficient, and the drum brake has high requirements for installation and coordination, and it is complicated. The transfer axle without parking brake has potential safety hazards. Therefore, the present invention provides a disc-type driving and parking integrated brake axle with functions of driving brake and parking brake. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a disc-type traveling and parking integrated brake axle with th...
