Embodiment

[0020] The attached drawing is just a diagram of the working principle of two pairs of symmetrical cylinder assemblies. Several pairs can be arranged side by side in one cylinder housing. Work on the drive shaft, and finally concentrate on the drive shaft to do work outwards.

[0021] The working principle of the stepless speed change is that the cylinder assembly is relatively arranged on the same axis. There is a swing arm with one end fixed in the middle of the cylinder assembly and an arc-shaped stepped rack at the other end. A chute is vertically arranged in the middle of the swing arm. There is a swing arm slider in the chute, and the oppositely arranged cylinder assemblies are connected together through a connecting rod. The swing arm slider is set in the middle of the connecting rod to drive the swing arm to swing left and right, and then drive the arc-shaped stepped rack to swing left and right to drive A group of one-way gears rotate, and the rotation of the one-way ...

Abstract

The invention provides a crankless piston type stepless speed change engine and a design method. Air cylinder assemblies are oppositely arranged on the same axis, a swing arm is arranged between the air cylinder assemblies, one end of the swing arm is fixed, the other end of the swing arm is provided with an arc-shaped step rack, a slide slot is vertically arranged in the middle of the swing arm, a swing arm slide block is arranged in the slide slot, the oppositely arranged air cylinder assemblies are connected together via a connection rod, the swing arm slide block is arranged in the middle of the connection rod to drive the swing arm to swing left and right and further drive the arc-shaped step rack to swing left and right so as to drive a group of one-way gears to rotate, the rotation of the one-way gears drives a transmission shaft to rotate continuously to output kinetic energy outwards, an air cylinder shell is adjusted by a synchronous ascending and descending mechanism arranged at the outer part of the air cylinder shell to move up and down along a slideway, and because the air cylinder assemblies are arranged in the air cylinder shell, the vertical movement of the air cylinder shell drives the swing arm slide block to move up and down in the slide slot of the swing arm, and the moment of the swing arm slide block driving the swing arm is changed via the change of the position of the swing arm slide block in the slide slot so as to change the swing amplitude of the arc-shaped step rack, the rotate speed of the transmission shaft is changed along with the change of the position of the swing arm slide block on the swing arm, and stepless speed change is realized.

Description

technical field [0001] The invention relates to an engine, in particular to a crankshaftless piston type continuously variable speed engine. Background technique [0002] Most of the piston engines in the prior art convert the reciprocating mechanical energy of the piston into rotational energy through the crankshaft connecting rod and output it through the output shaft. Own weight and fuel consumption. Contents of the invention [0003] The invention provides a crankshaftless piston type continuously variable speed engine and a design method. [0004] The design method of the crankshaftless piston type continuously variable transmission engine of the present invention is realized in the following manner. The cylinder assemblies are relatively arranged on the same axis, and one end of the cylinder assembly is fixed, and the other end is provided with an arc-shaped stepped rack. Swing arm, a chute is vertically arranged in the middle of the swing arm, and a swing arm slid...
