Embodiment 1

[0082] Example 1, Figure 14 It is one of the design structures of the piston without sealing ring. During the compression process, when the piston moves toward the cylinder head, the liquid working meson flows through the side wall of the piston and the cylinder body at high speed to form a high-pressure oil film.

Embodiment 2

[0083] Example 2, Figure 15 It is the second design structure of the piston without sealing ring. This structure is that the top surface of the piston and the side wall of the piston are connected by a 0-20 degree conical surface formed with the side wall of the piston in the circumferential direction. During the compression process, when the piston moves toward the cylinder head, the liquid working meson is guided by the tapered surface and flows through the piston side wall and the cylinder at high speed to form a high-pressure oil film.

Embodiment 3

[0084] Example 3, Figure 16 It is the third design structure of the piston without sealing ring. The piston top and the piston side wall are connected through the through hole, and the liquid working meson directly acts on the piston side wall and the cylinder through the through hole to establish a high-pressure oil film.

Abstract

The invention provides a reciprocating motion type sealing ring-free piston hydraulic brake device which comprises a hydraulic cylinder, a clutch mechanism and a transmission mechanism, wherein the hydraulic cylinder is provided with a cylinder cover, a cylinder and a sealing ring-free piston capable of moving in the cylinder in a reciprocating manner; the clutch mechanism is provided with a clutch shell and a crankshaft body connected to each other, and a crankshaft is arranged in the crankshaft body; forces generated by compressing and pumping the sealing ring-free piston form a restoring torque which is transferred to the crankshaft and is transferred to a spindle of a power device through the clutch mechanism; and the transmission mechanism which drives the sealing ring-free piston tomove is provide with a crankshaft connecting rod connecting disc connected to the crankshaft, a connecting rod pin connected to the crankshaft connecting rod connecting disc, a connecting rod connected to the connecting pin and a piston pin connected to the connecting rod, and the piston pin is connected to the sealing ring-free piston to drive the sealing ring-free piston to move. The reciprocating motion type sealing ring-free piston hydraulic brake device is simple in structure, convenient to manufacture, flexible to mount, few in liquid working medium, high in brake efficiency and good inreliability.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2019105434461, the application date is June 21, 2019, and the invention title is "reciprocating motion type piston hydraulic brake device without sealing ring". technical field [0002] The invention relates to the field of mechanical engineering, in particular to a reciprocating piston hydraulic braking device without a sealing ring. Background technique [0003] A common hydraulic retarder is composed of a rotor, a stator, a working chamber, an input shaft, a heat exchanger, an oil storage tank and a housing. The stator and the rotor face each other to form a working cavity which communicates with the working fluid storage tank (oil pool) through a valve. When slowing down, the electronic control system controls the proportional valve to apply air pressure to the working fluid storage tank to fill the working fluid into the working chamber, and the rotor gene...
