Description
Technical field
The utility model relates to a kind of transmission system, especially a kind of soft axle transmission system suitable for motorcycle.
Background technique
Soft axle transmission system suitable for motorcycle be for substituting a kind of chaindriven transmission system of motorcycle tradition,
Using closed transmission case and soft axle transmission mode, the open chain drive that effectively overcomes existing motorcycle to generally use it is easy
The defects of abrasion, clamping stagnation, damage and fracture, it can be obviously improved transmission system service life, and ensure personnel safety of riding.For
This, the applicant has submitted multiple patent applications, many Shens to State Intellectual Property Office so far from March, 2012
It has please been granted patent right, meanwhile, product also in continuous improve, to better adapt to market, meets client and needs to ask.
Existing motorcycle flexible shaft transmission system include the transmission case for being respectively used to connect with motorcycle engine and rear wheel hub in motorcycle and
Driving box passes through driving snake between two headstocks and connects.Since driving box directly drives hub of motorcycle, output torque
Larger, rigidity, intensity, the accuracy of manufacture and the assembly precision of associated components require higher.Existing driving box is primarily present following
The deficiency of two aspects forms level-one first is that driving box usually passes through driving input bevel gear and driving output bevel gear circle engagement
Bevel gear pair deceleration transmission, but driving input bevel gear is in cantilever mounting structure, and stability is poor, and bending resistance is easy to cause
Driving box fatigue life reduces.The second is driving box mainly has mounting structure at two, be at one on cabinet between chain stay
Mounting connection structure, another place are the fixed connection structures between the support tube and rear-wheel central axis being arranged by cabinet.Due to
Existing support tube is fixedly connected on cabinet by the flange that wherein one end is arranged, and when installation, support tube small end is against rear-wheel
Hub bearing end face, flange end is by screwing togather nut on center shaft and fastening on center shaft.Since ring flange is located at
Outside cabinet, installation condition is that inner face is pressed on cabinet, necessarily forms biggish nut and compaction forces to body side, and
Cabinet is fixedly connected on chain stay itself again, chain stay vehicle driving necessarily occur during jolting certain amplitude relative to
The swing of central axis.Two different active forces in position difference, direction collectively form the fatigue load of cabinet, shorten cabinet
Fatigue life.In addition, the flexible axle of existing motorcycle flexible shaft transmission system is although have certain flexibility, since it must have
Sufficiently large torque drive requirement.Therefore, flexible characteristic is necessarily subject to certain restrictions；It is formed if after mounting a certain amount of
Prebuckling, necessarily occur in subsequent normal use process flexible axle bending deformation superposition, cause flexible axle fatigue life reduce.
For this reason, it may be necessary to be further improved.
Summary of the invention
The purpose of this utility model deficiency low aiming at driving box fatigue life in the prior art, provides a kind of flexible axle
Transmission system, the system form both ends support construction by the driving input shaft of driving box, to improve driving input shaft rigidity, fortune
Row stability and bending resistance then improve cabinet force-bearing situation, improve cabinet fatigue life.Its structure is simple, compact layout.
To realize foregoing purpose, the utility model adopts the following technical solution.
