Abstract
The invention relates to a center shaft assembly of a bicycle, in particular to a left one-way bearing shaft of a bicycle with pedals rotating forwards and backwards for driving. The left one-way bearing shaft of the bicycle with the pedals rotating forwards and backwards for driving is characterized in that an internal thread through hole is formed along the axis of the shaft and provided with a left-hand thread, the left one-way bearing shaft is provided with an external thread end, a shaft neck, a regular-polygon convex step and a shaft shoulder in sequence from left to right, and a key groove is formed in the shaft neck. The left one-way bearing shaft of the bicycle with the pedals rotating forwards and backwards for driving is unique and ingenious in design, easy to manufacture, long in service life, convenient to mount, demount and maintain, good in trial effect and beneficial to solving the long-standing problem that a left bevel gear swings, and the reliability of a center shaft assembly of the bicycle with the pedals rotating forwards and backwards for driving is significantly improved.
Description
Technical field
The present invention relates to the middle axle assembly of bicycle, be more particularly to the left unilateral bearing axle of a kind of bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates.
Background technology
Bicycle is mainly by vehicle frame, middle axle assembly, trailing wheel, front-wheel, chain, chain drum, flywheel, the parts such as pedal, brake form, the axis assembly structure of existing bicycle is fairly simple, mainly it is made up of central axis seat, axis, bearing, chain drum, cripple etc., general bicycle is all unidirectional drive, i.e. left and right foot drives bicycle when stepping on forward.The present inventor has applied for bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates on February 19th, 2012, Authorization Notice No.: CN102582771B, authorized announcement date: on May 1st, 2013, patent right number, ZL201210036555.2, this bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates successfully realizes pedal bi-directional driving bicycle.But, find in practice, bicycle middle shaft assembly structure is unreasonable, and wherein axle assembly the most easily goes wrong, and service life is short, install, dismantle inconvenience, left side bevel gear easily swings, and has a strong impact on the using effect of bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates, for this, have much room for improvement the middle axle assembly of bicycle, needs to be explored the left unilateral bearing axle of bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates.
Summary of the invention
The purpose of the present invention: the left unilateral bearing axle of a kind of bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates is provided.
The technical scheme is that the left unilateral bearing axle of a kind of bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates, it is characterized in that, axis along axle is provided with internal thread through hole, internal thread through hole is anti-silk tooth, left unilateral bearing axle is from left to right followed successively by male end, axle journal, the most polygon convex rank, the shaft shoulder, is provided with keyway on axle journal.
The left unilateral bearing axle of described bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates, its described polygon convex rank are the convex rank of regular hexagon.
The left unilateral bearing axle of bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates described above, the overall length of its described internal thread through hole is 44 millimeters, silk tooth is the anti-silk tooth of M16 × 1, a length of 8 millimeters of male end, silk tooth is M24 × 1.5, a length of 14 millimeters of axle journal, a diameter of 25 millimeters, a length of 13 millimeters of the most polygon convex rank, a diameter of 50 millimeters of the circumscribed circle on polygon convex rank, a length of 9 millimeters of the shaft shoulder.
The left unilateral bearing axle of the bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates of the present invention, it is mounted in the left side of bicycle middle shaft, the shaft shoulder is for propping up the bearing inner race on the bicycle middle shaft left side, the most polygon convex rank are used for rotating this week, axle journal is used for installing bearing, and male end tightening nut props up the inner ring of the bearing installed on axle journal, and internal thread through hole is for being arranged on the bicycle middle shaft left side by left unilateral bearing axle, keyway is used for installing key, the bearing inner race that fixing axle journal is installed.The left unilateral bearing axle of the bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates of the present invention can be with steel part or Al-alloy parts.
Beneficial effects of the present invention: the left unilateral bearing axle design of the bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates of the present invention is unique, ingenious, make easily, service life is long, install, dismounting, easy to maintenance, trial effect is good, it favorably solves the swing hard nut to crack of left side bevel gear, significantly improves the reliability of axle assembly in bicycle driven by clockwise rotation and anticlockwise rotation of pedal plates.
