The invention provides a hydraulic braking device, and belongs to the field of hydraulic control. The hydraulic braking device comprises a shell, a driving assembly and multiple braking oil cylinders.An oil drainage opening is formed in the outer wall of the shell. Each braking oil cylinder comprises a cylinder body, a piston, a piston rod and a rotary sleeve. A first through hole and an oil inlet are formed in the circumferential wall of each cylinder body, the outer circumferential wall of each piston is in running fit with the inner circumferential wall of the corresponding cylinder body,one part of each piston rod is coaxially inserted into the corresponding piston, and the other part of each piston rod stretches relative to the shell and is used for being connected with a movable body. Each rotary sleeve movably and coaxially sleeves the corresponding cylinder body, and multiple second through holes are circumferentially formed in the circumferential wall of each rotary sleeve.The aperture of the second through holes located in the same radial section is gradually reduced in the circumferential direction, and the second through holes communicate with the oil drainage opening through the first through holes. The driving assembly is configured to drive the multiple rotary sleeves to rotate synchronously. The hydraulic braking device can be suitable for braking cars with different masses.
Description
technical field [0001] The disclosure belongs to the field of hydraulic control, in particular to a hydraulic braking device. Background technique [0002] During the manufacturing process of automobiles, relevant simulation experiments are often carried out on the driving performance of automobiles, so as to study and improve the driving performance of automobiles. [0003] Due to the limitation of the field factors, the car needs to brake after the simulation experiment, so that the car can stop moving in the limited field. In the related art, the braking of the automobile is realized through the hydraulic brake cylinder, specifically, the hydraulic brake cylinder is fixedly installed, and then the automobile and the hydraulic brake cylinder are connected together through a rope. Before the test, the rope is in a loose state, and after the test is completed, the rope is in a tense state, thereby acting on the piston rod of the hydraulic brake cylinder, and then driving th...
