The invention provides a hydraulic integrated brake-by-wire system, and belongs to the field of automobile brake systems, the hydraulic integrated brake-by-wire system comprises a main cylinder, a first piston, a second piston, a first oil can, a second oil can and an energy accumulator, the first piston and the second piston divide an inner cavity of the main cylinder into a first cavity, a second cavity and a third cavity, and the end, away from the main cylinder, of the first piston is connected with a pedal; a first loop and a second loop are connected between the second cavity and the wheel cylinder set, a third loop is connected between the first cavity and the wheel cylinder set, an oil pump is connected to the first loop in series, the energy accumulator is located between the oil pump and the second cavity, the first oil can is communicated with the first cavity through a pipeline, and the second oil can is communicated with the second cavity and the wheel cylinder set through pipelines. And the first oil pot and the second oil pot are mutually independent. The problem that an existing electronic hydraulic braking system is limited in redundancy capacity is solved. The method has the technical effects that reliable voltage buildup with higher power and higher braking response speed are realized, and the braking effect of redundant braking is ensured while braking decoupling is realized.

The present invention discloses a pneumatic electronic parking brake module for a commercial vehicle, and relates to the technical field of commercial vehicle braking. The pneumatic electronic parking brake module for a commercial vehicle comprises a controller 50, a housing 56, a relay valve 4, a two-position two-way solenoid valve 1, a two-position two-way air control valve 2, a two-position three-way solenoid valve 3, a first drive solenoid coil 90, and a second drive solenoid coil 91. The overall design is integrated, and compared with a traditional parking brake system, the connection between pneumatic pipelines and electrical circuits is reduced, and the module has the advantages of high integration, small installation space, and high reliability. At the same time, the integrated installation is also convenient for subsequent maintenance, which can reduce maintenance costs.

The invention relates to a hand brake type semi-self-service aviation dining car which comprises a dining car body, a water receiving module, a braking module and driving wheels, the driving wheels are arranged at the bottom of the dining car body, the braking module is arranged on the dining car body and connected with the driving wheels, the water receiving module is located at the top of the dining car body, and a water tank module is arranged in the dining car body.

Compared with the prior art, the device has the advantages that the hand brake is convenient and reliable to brake, the water receiving module realizes semi-self-service, the operation and safety are high, and the like.

This utility model discloses an integrated driving and parking braking structure for electric tricycles. Relating to the field of electric tricycle technology, the utility model includes a vehicle body, with a drive device rotatably connected to the inner wall of the vehicle body via a pivot. Through the cooperation of the drive device and the passive device, this integrated driving and parking braking structure integrates driving and parking braking into one unit, overcoming the limitation of independent driving and parking braking in traditional electric tricycles. This structure centralizes related components, reducing the space occupied inside the vehicle and making the vehicle structure more compact and reasonable. For the driver, unlike traditional vehicles, there is no need to use different operating components for driving and parking braking; both braking functions can be completed using only the brake pedal. In emergency situations, this allows the driver to react more quickly and accurately, improving driving safety and convenience.
