The invention discloses a kind of freely-supported beam type straddle-type single-track vehicle double-shaft power bogie, including support frame and traveling wheel assembly, travelling wheel installation cavity is provided with support frame as described above, traveling wheel assembly is arranged in travelling wheel installation cavity, its innovation is：Support frame as described above and traveling wheel assembly use simple beam structure；The method have the benefit that：There is provided a kind of new freely-supported beam type single-track vehicle bogie support structure, the stressing conditions of structure can be effectively improved, solve the problems, such as tire eccentric wear.
Description
Technical field
It is dynamic the present invention relates to a kind of straddle-type single-track vehicle, more particularly to a kind of freely-supported beam type straddle-type single-track vehicle twin shaft
Power bogie.
Background technology
At present, it is used to support the support shaft of travelling wheel on straddle-type single-track vehicle using beam type supporting structure, branch
The outer end for holding axle is connected with power assembly, and power assembly is arranged at the opening portion on support frame, the inner hanging and position of support shaft
Inside support frame, travelling wheel is socketed on the inner of support shaft, and its purpose of design is：Because stress is huge suffered by travelling wheel,
Abrasion is very fast, and its maintenance period is shorter, and from from the point of view of travelling wheel easy to disassemble, prior art employs previous designs,
During dismounting, the opening portion that support shaft and travelling wheel just can be from support frames outwards removes, after the completion of attended operation, then will supporting
Axle and travelling wheel are installed along with support frame；The problem of presence is：As a result of beam type supporting structure, support frame institute
The negative stress for bearing more is concentrated, unbalance stress and regional area stress is huge, meanwhile, the load born on travelling wheel
There is eccentric wear in skewness, tire, and because structure is special, it is impossible to radial wheel rim is used, can only, knot larger using volume
The complicated Special hub of structure, not only cost is higher for this wheel hub, and quality is larger, although beam type supporting structure causes to move
Power assembly and support shaft, travelling wheel can be by integral demounting but follow-up tire changing operation it is still very cumbersome, time-consuming,
Efficiency is low；Further, since its support shaft needs to bear huge stress, thus support shaft not only quality is huge but also structure multiple
It is miscellaneous.
The content of the invention
For the problem in background technology, the present invention proposes a kind of freely-supported beam type straddle-type single-track vehicle double-shaft power and turns
To frame, including support frame and traveling wheel assembly, travelling wheel installation cavity is provided with support frame as described above, traveling wheel assembly is arranged at away
In road wheel installation cavity, its innovation is：The traveling wheel assembly includes support shaft, two wheel rims, two wheels and two groups of bearings,
The support shaft middle part is provided with the T-shaped plate-like projection of shaft section, and left section of external diameter in plate-like projection is more than right section of external diameter；Institute
State wheel rim to be made up of supporting part, terminal pad and conical cylinder section, the terminal pad middle part is provided with mounting hole, the internal diameter of the mounting hole
Matched with right section of external diameter in plate-like projection；The wheel is socketed on supporting part, and supporting part and terminal pad are coaxially disposed, support
Connected by conical cylinder section between portion and terminal pad, terminal pad is located at the inner side of supporting part；The axial width of the terminal pad is designated as
A, the right segment length in plate-like projection is more than or equal to 2A；The terminal pad of two wheel rims is stacked together, and terminal pad is by installing
Borehole jack is connected on right section of plate-like projection, is bolted between terminal pad and left section of plate-like projection, and two groups of bearings cover respectively
It is connected on support shaft two ends；The both sides of travelling wheel installation cavity are each provided with a bearing block on support frame, between bearing block and support frame
Bolt connection, two groups of bearings are respectively arranged in two bearing blocks.
Principle of the invention is：After the present invention program, travelling wheel supporting structure by original beam type become in order to
Typical freely-supported beam type, this can be with so that the negative stress in support shaft more disperses, it is to avoid form larger in regional area
Stress, simultaneously as the change of force structure, the load born on travelling wheel is also distributed more uniform, can effectively change
Kind tire eccentric wear problem, further, since two wheels are located at support shaft middle part, two wheels can be relatively simple by two structures
Wheel rim is supported, it is to avoid using structure is special, expensive Special hub；In terms of dismounting, using this hair
After bright scheme, bearing block need to be only released from support frame just can integrally pull down support shaft and wheel.
The method have the benefit that：There is provided a kind of new freely-supported beam type single-track vehicle bogie support structure,
The stressing conditions of structure can be effectively improved, tire eccentric wear is solved the problems, such as.
