Abstract
A kind of front suspension fork of bicycle Vertical dimension fatigue tester, is made up of controller, linear stepping motor, force snesor, front fork clamp, force fixture, frame.Linear stepping motor is arranged in frame, and installing force sensor on the multi-rotor screw of linear stepping motor also connects force fixture by force snesor; Front fork clamp is arranged in frame for installing front suspension fork of bicycle test specimen; Controller is electrically connected with linear stepping motor, force snesor respectively.This testing machine can meet " torture test of front suspension fork of bicycle Vertical dimension " in QB1881--2008 " bicycle front fork " standard, and especially it is simple and reliable for structure.
Description
Art
The utility model relates to one can meet " the front suspension fork of bicycle Vertical dimension fatigue tester " that " torture test of front suspension fork of bicycle Vertical dimension " in QB1881--2008 " bicycle front fork " standard require, the front suspension fork of bicycle Vertical dimension fatigue tester that especially structure is simple, easy to operate.
Background technology
Open (bulletin) number: CN203178082U known at present and open (bulletin) number: " a kind of front suspension fork of bicycle level is to fatigue tester " involved by CN103712804A is adopt linear electric motors to be drive source.Although linear electric motors can provide high speed and high acceleration, its volume is comparatively large, and particularly it controls, debugs and safeguard rather complicated, operation inconvenience.
Summary of the invention
Larger in order to improve current linear electric motors volume, particularly it controls, debugs and safeguards complicated, unhandy problem, it is drive source with linear stepping motor that the utility model provides a kind of, meets the front suspension fork of bicycle Vertical dimension fatigue tester that QB1881--2008 " bicycle front fork " standard " torture test of front suspension fork of bicycle Vertical dimension " requires.This testing machine reliability and good stability, maintenance are simple, easy to use.
The technical scheme that the utility model adopts is: form front suspension fork of bicycle Vertical dimension fatigue tester by controller, linear stepping motor, force snesor, front fork clamp, force fixture, frame.Described linear stepping motor is arranged in frame, and installing force sensor on the multi-rotor screw of linear stepping motor also connects force fixture by force snesor; Described front fork clamp is arranged in frame for installing front suspension fork of bicycle test specimen; Described controller is electrically connected with linear stepping motor, force snesor respectively.
When controller drives linear stepping motor to move, the multi-rotor screw of linear stepping motor by force snesor and force fixture to the front suspension fork of bicycle test specimen imposed load be arranged between force fixture and vertical tube of front fork fixture, the change that force snesor is exerted oneself according to the size detection of imposed load thrust, then convert electric signal to and be sent to controller, controller, according to this signal and the predetermined load applied, controls the motion of linear stepping motor; When reaching predetermined imposed load, controller drives linear stepping motor drawback movement, carries out reverse imposed load; When reaching predetermined reverse imposed load, controller drives linear stepping motor drawback movement again.And so forth, realize applying alternate load and carry out the torture test of front suspension fork of bicycle Vertical dimension.
The beneficial effects of the utility model are, owing to have employed the linear stepping motor of technology maturation, structure is simple, reliability and good stability; And the utility model it is with low cost, maintenance is simple, and end user is without the need for any commissioning experience.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. controllers, 2. linear stepping motor, 3. force snesor in figure, 4. exert a force fixture, 5. vertical tube of front fork fixture, 6 frames; 7. front suspension fork of bicycle test specimen
Embodiment
In FIG, controller (1) is electrically connected with linear stepping motor electricity (2), and force snesor (3) is electrically connected with controller (1); Linear stepping motor (2) is arranged in frame (6), multi-rotor screw and the force snesor (3) of linear stepping motor (2) are mechanically connected, and connect force fixture (4) by force snesor, vertical tube of front fork fixture (5) is arranged in frame (6), for installing front suspension fork of bicycle test specimen (7).
Before test starts, the standpipe of front suspension fork of bicycle test specimen (7) is installed on vertical tube of front fork fixture (5).When starting to test, controller (1) drives linear stepping motor motion, the multi-rotor screw of linear stepping motor (2) by force snesor (3) and force fixture (4) to being arranged on front suspension fork of bicycle test specimen (7) imposed load exerted a force between fixture (4) and vertical tube of front fork fixture (5); The change that force snesor (3) is exerted oneself according to the size detection of imposed load thrust, then convert electric signal to and be sent to controller (1), controller (1), according to this signal and the predetermined load applied, controls the motion of linear stepping motor (2); When reaching predetermined imposed load, controller (1) drives linear stepping motor (2) to return.And so forth, the torture test of front suspension fork of bicycle Vertical dimension is realized.
Claims (1)
1. a front suspension fork of bicycle Vertical dimension fatigue tester, is characterized in that comprising controller, linear stepping motor, force snesor, front fork clamp, force fixture, frame; Described linear stepping motor is arranged in frame, and installing force sensor on the multi-rotor screw of linear stepping motor also connects force fixture by force snesor; Described front fork clamp is arranged in frame; Described controller is electrically connected with linear stepping motor, and force snesor is electrically connected with controller.
