Speed change device with coaxial connecting rod rolling disc

Abstract

The invention relates to a speed change device with a coaxial connecting rod rolling disc. The speed change device comprises a speed changer shell containing a body. The body comprises the coaxial connecting rod rolling disc, a force-input shaft, a centrifugal piece, a plurality of counterweight assemblies, a plurality of O rings and a plurality of sliding block assemblies. When the speed change device conducts actuation, the force-input shaft serves as a force applying point of the lever principle, the equal sliding block assemblies serve as weight points, and the arm of force is equal to thedistance between the force-input shaft and each equal sliding block assembly; the equal sliding block assemblies are arranged at the tail end of the connecting rod rolling disc, therefore, compared with the prior art, the arm of force is increased, the bearing force of the weight points is improved, the turning force of the speed change device is increased under the same motor force, and accordingly the motor force is saved; and in addition, U-shaped grooves for containing the equal sliding block assemblies are formed in the tail end of the connecting rod rolling disc, so that machining is easy during manufacturing, and the cost can be reduced.

Description

technical field [0001] The invention relates to a speed change device, in particular to a speed change device with a coaxial connecting rod roller with an eccentric wheel of the connecting rod roller. Background technique [0002] The speed change device is often installed on a motor vehicle or an electric bicycle. The slider body in the speed change device is driven by a motor to rotate the speed change device, which further drives the wheels to rotate, so that the car and motorcycle can move forward. [0003] see Figure 8 As shown, a conventional speed change device 60 is through a plurality of hollow holes 62 engraved on a speed change plate 61, and a plurality of slider bodies 63 are assembled on the speed change plate 61, and by rotating the speed change plate 61, these The slider body 63 rotates; in action, an input shaft 64 of the speed change device 60 is used as the force point, and the slider bodies 63 are gravity points. At this time, the length L of a moment arm...
