Embodiment Construction

[0015] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] The hydraulic suspension control system of the variable module provided by the present invention is independently adopted in a single vehicle figure 1 In the grouping form shown, the oil passages of the third suspension and the fourth suspension are controlled together, the hydraulic oil can flow freely between the two, and the load balance is realized. The oil passages of the first suspension and the second suspension are independent, thus realizing the whole The three-point support of the car.

[0017] The hydraulic suspension control system of the variable module provided by the present invention adopts the figure 2 The grouping format shown. Control the oil circuit connection of the first suspension and t...

Abstract

The invention relates to a hydraulic suspension control system provided with variable modules and belongs to the technical field of an omni-bearing intelligent moving platform. Suspension oil cylinder assemblies are adopted to support wheels, the connecting form of different suspension oil cylinder assemblies is adjusted through switching of on-off of different hydraulic valves, and three-point grouping, two-point grouping and single-point grouping of suspensions are realized. In a two-vehicle splicing and using process, whole three-point support after splicing of the two vehicles is realized through two-point grouping of the front vehicle and single-point grouping of the back vehicle, and the reference height of each suspension module is adjusted by adjusting the amount of oil injected into the corresponding suspension oil cylinder assembly; the oil pressure of the suspension oil cylinder assemblies is measured by oil path pressure sensors, and the load and offset load conditions of the whole vehicle can be obtained in real time.

Description

technical field [0001] The invention relates to the technical field of omnidirectional intelligent mobile platforms, in particular to a hydraulic suspension control system of variable modules. Background technique [0002] The omnidirectional mobile platform based on mecanum wheels must ensure that the driving wheels touch the ground at the same time, so as to provide effective driving force and bearing capacity to realize the omnidirectional movement of the platform. However, the conventional ground cannot be absolutely level, which requires wheel suspension to ensure that the wheels bounce up and down. Conventional spring suspensions are difficult to balance the loads of different wheels, and it is difficult to measure the load status of the wheels in real time. When multiple omnidirectional mobile platforms are spliced ​​and used, it is more difficult to realize the three-point support of the spliced ​​large platform due to the multiplied number of wheels. Contents of ...
