Cone wheel type bicycle with steel ball stepless speed change mechanism

Abstract

The invention discloses a cone wheel type steel ball stepless speed change mechanism for bicycles, which comprises an input disc, an output disc, an axle speed regulating mechanism, a rolling bearing speed change mechanism and a supporting guide device; the input disc and the transmission sprocket drive mechanism connection, the output disk is connected with the output casing of the transmission; the moving nut of the axle speed regulating mechanism passes through the through hole in the middle of the axle, and forms a spiral connection with the gear speed regulating shaft; the two steel ball mandrels of the rolling bearing speed regulating mechanism are two The ends are respectively connected with the left and right push rods to form a sliding-rolling pair; the guide frame supporting the guide device is installed on the cone wheel slider, between the two vertical guide discs, and forms a vertical track with the vertical guide disc. The present invention changes the inclination angle of the speed change steel ball axis to change the distance between the input disk and the output disk and the speed change steel ball axis, thereby changing the speed ratio to achieve the purpose of speed change. The invention has the advantages of simple structure, stable transmission, convenient processing and manufacturing.

Description

technical field [0001] The invention relates to a continuously variable speed change mechanism, in particular to a continuously variable speed change mechanism for bicycles. Background technique [0002] Today, when energy conservation and environmental protection are advocated, bicycle travel has become an advocated way of travel. Bicycles can be roughly divided into variable speed and non-variable speed bicycles, but non-variable speed bicycles have low riding efficiency, cannot cope with various terrains well, and ride more strenuously; there are many kinds of speed change mechanisms for variable speed bicycles. The most widely used bicycle transmission mechanism is the tower wheel transmission mechanism. This transmission mechanism uses multiple sprockets of different sizes to achieve stepped transmission. The transmission process is not stable, and there is a shifting shock, which cannot satisfy cycling requirements, so future bicycles should tend to be more continuous...

Bicycles can be roughly divided into variable speed and non-variable speed bicycles, but non-variable speed bicycles have low riding efficiency, cannot cope with various terrains well, and ride more strenuously; there are many kinds of speed change mechanisms for variable speed bicycles. The most widely used bicycle transmission mechanism is the tower wheel transmission mechanism. This transmission mechanism uses multiple sprockets of different sizes to achieve stepped transmission. The transmission process is not stable, and there is a shifting shock, which cannot satisfy cycling requirements, so future bicycles should tend to be more continuously variable; while some foreign bicycles are equipped with continuously variable transmissions, among which Nuvinci CVT is a well-known bicycle CVT, which uses a set of rigid A small ball with a fixed axis is used to change the transmission ratio. Since continuous speed changes can be achieved, the bicycle can better meet the riding needs.
