Description
Technical field
The present invention relates to a kind of motorcycle durability experimental rig, especially a kind of motorcycle Kick-start bar assembly pedals bar rotation
Turn durability test apparatus and test method.
Background technology
Motorcycle starting mode is nothing more than there is electrically actuated and two kinds of Kick-start at present, and in China, most of motorcycles all can
Selection collocation Kick-start.Motorcycle is when carrying out Kick-start, in addition to normal start-up function, it is also necessary to which bar progress is pedaled in operation
" gathering " and " opening " action is completed in rotation, that is, is pedaled bar and met the base that can be born the impact force that foot is kicked and realize motorcycle ignition
Outside this function, it should be able to also meet reliable location and flexibly open this two big function.And most of producers all only focus on motorcycle
Whether Kick-start mechanism can meet start request, more have ignored pedal bar rotation failure after to user bring it is many not
Just.
There are two types of the rotation modes for pedaling bar in common Kick-start bar assembly on the market, and one is pedal bar 2 to be mounted on
It is that " gathering " and " opening " is realized in fulcrum rotation with starting handle 1 in lever 1（See Fig. 1）；Another is to pedal bar 2 to be mounted on song
It turns on seat 1, is that " gathering " and " opening are realized in fulcrum rotation with crank throw seat 1（See Fig. 2）”.
It pedals bar and rotates the durable attention rate according to manufacturer, it is general to carry out 3000 times to 20000 times.If all by manpower
It completes, must can make the significant losses of personnel's muscle power and cannot achieve continuous starting test for a long time, to cause experiment week
Phase is long.
Therefore it is a kind of simple in structure it is necessary to design, easy to operate pedals bar rotation durability testing device, can replace
Artificial realize pedals the durability test operation that bar recoil starts, and reaches saving manpower, improves the effect of test efficiency.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：How a kind of structure letter is provided
Single, easy to operate motorcycle Kick-start bar assembly is pedaled bar rotation durability testing device and test method, can be replaced
Artificial realize pedals the durability test operation that bar recoil starts, and reaches saving manpower, improves the purpose of test efficiency.
In order to solve the above-mentioned technical problem, the following technical solution is used in the present invention：
A kind of motorcycle Kick-start bar assembly pedals bar rotation durability testing device, which is characterized in that including bottom plate, bottom plate
On be provided with recoil starting bar assembly installing mechanism, the recoil starting bar assembly installing mechanism includes one with being horizontally mounted
The installation protrusion in hole and a cooperation are being horizontally mounted in hole and are installing for realizing recoil starting bar assembly and prevent its turn
Dynamic splined shaft；It is correspondingly arranged on above the recoil starting bar assembly installing mechanism and applies for realizing holding and control to pedaling bar cramp
The clamping force application mechanism of power, the clamping force application mechanism are supported by a supporting mechanism and are fixed.
Test method disclosed by the invention, even if with above-mentioned apparatus, using the installation of splined shaft and recoil starting bar assembly
Hole coordinates, and recoil starting bar assembly is installed on recoil starting bar assembly installing mechanism so that it is upward to pedal bar one end, by being clamped
Force application mechanism realizes the clamping for pedaling bar and left and right force, you can foot kicks the operation for pedaling bar repeatedly for simulation, and it is durable that bar rotation is pedaled in realization
Experiment.With advantage simple in structure, easy to operate, reach saving manpower, improves the purpose of test efficiency.
As an optimization, the recoil starting bar assembly installing mechanism includes the mounting bracket of an inverted T-shaped, the installation branch

The advantages of.
As another optimization, the clamping force application mechanism includes an engine being fixed on supporting mechanism, even
It is connected below engine and there are two what is extended downwardly to be used for for setting on the turntable that engine drive rotates horizontally, the turntable
Realize the supporting rod held to pedaling bar cramp.
In this way, realizing the clamping to pedaling bar by a pair of of supporting rod, then turntable is driven to rotate back and forth realization to pedaling by engine
The simulation that bar method is trampled, action is relatively reliable, and simulation is more efficient, it is ensured that the reliability of test result.
As an optimization, there is the thread segment that a diameter becomes smaller, the thread segment to be connected to circumferentially for the supporting rod upper end
In the through-hole for an arc being arranged on turntable, there are one the step that width becomes larger, the thread segments for the through-hole top tool
A upper nut by coordinating is articulated on step, and to push against at supporting rod threaded upper ends section step and be fixed on turntable lower end
Face.
After optimizing in this way, position of the supporting rod on turntable circumferentially can be easily adjusted, it is made to be conducive to be held in place,
When being clamped simultaneously, threaded rod is unclamped and is locked using very convenient quickly realize of simple structure so that clipping operation is very
It is convenient and efficient effective.
Further, the supporting rod has a rubber elastic layer for realizing the outer surface of clamping.It in this way can be more
Facilitate clamping fastener.
Further, the engine is rotary cylinder.In this way, cost is cheaper and conducive to control.
In conclusion the present invention has advantage simple in structure, easy to operate；Artificial realization can be replaced to pedal bar anti-
The durability test operation that punching starts, reaches saving manpower, improves the effect of test efficiency.
