Shaft Synergistic Three-Dimensional Wobble Plate Piston Engine

Abstract

The invention discloses a shaft-coordinated three-dimensional wobble plate piston engine, which includes a base body, a main shaft, a cylinder body, a transmission assembly and a coordinating shaft assembly; the cylinder body includes at least two cylinders arranged in a circular array in parallel around the central axis, and the transmission assembly includes a wobble plate , the coordinated shaft assembly includes at least two coordinated shafts arranged around the central axis, and the two ends of the coordinated shaft are respectively matched with the swing plate and the cylinder body through a cylindrical pair to achieve relative rotation and reciprocating motion, so as to cooperate with the cylinder body and the swing plate The synchronization between them in the circumferential direction makes the connecting rod only transmit the reciprocating driving force, and does not participate in the transmission of the load that maintains the synchronization between the wobble plate and the cylinder in the circumferential direction, removes the commonly used slider structure in the prior art, and simplifies the connecting rod and piston. The connection relationship between the connecting rod and the wobble plate makes the overall structure simple and light, prolongs the service life of the connecting pair, and saves manufacturing and use costs. The invention adopts a rotary cylinder gas distribution structure, which is compact, simple, high The volume ratio is large, the radial load of the piston is small, and the mechanical efficiency of the whole machine is high; the engine is set as a cylindrical structure with a small windward area, which is used for sports machinery to reduce resistance, and is suitable for aero engines.

Description

technical field [0001] The invention relates to the field of transmission drive, in particular to a shaft-coordinated three-dimensional wobble plate piston engine. Background technique [0002] The axial piston device is driven or driven by a cylinder arranged around a central axis, a piston matched with the cylinder, and a rotating wobble plate; the basic structure is that the piston is connected to the wobble plate through a connecting rod, and the reciprocating motion of the piston is transmitted to the oscillating plate through the connecting rod. The disk is transformed into a rotational output by using the cam transmission principle of the wobble disk; or, the wobble disk is driven by the periodic axial swing to periodically change the axial position and drive the piston through the connecting rod to form a reciprocating motion and perform work. [0003] From the above structure, it can be seen that relative to the cylinder body, it is expected that there will be no re...

Problems solved by technology

[0003] From the above structure, it can be seen that relative to the cylinder body, it is expected that there will be no relative rotation in the circumferential direction between the wobble plate and the cylinder body. The piston still transmits the power of the piston to the wobble plate, and the wobble plate is subject to the component force in the circumferential direction. Therefore, the connecting rod also constrains the coordinated action between the wobble plate and the cylinder (piston), so the bearing is more complicated and has various directions. The deflection moment; therefore, the usual structure adopts the sliding shoe structure to adapt to the azimuth change in all directions and undertake more complex deflection moment, the structure is more complicated; the sliding shoe structure needs to have sufficient lubrication, which not only makes the structure extremely complicated, but also prone to occurrence Wear leads to machine failure; due to the above problems, the existing technology is rarely used in the case of engines, high speed and load will quickly fail the axial piston structure
