The synchronizer gear ring abrasion endurance testing machine has the advantages that by the improvement for the synchronizer gear ring abrasion endurance testing machine, a driving shaft can be separated from a motor by power, and the inertia of a flywheel is changed and the performance of a speed changing box during actual gear shifting can be actually simulated at the same time, so that the requirement of the original synchronization ring abrasion performance test can be met, and the requirements for different inertias of synchronization ring individual test can be met; therefore, the performance of a synchronization ring can be really tested under the working condition of actual inertia, and the synchronization ring is accurately evaluated.
Description
Technical field
The present invention relates to the testing equipment technical field, specifically modified synchro converter ring abrasion durability-testing machines and method of operating thereof.
Background technology
Along with further developing of automobile industry, market competition is more fierce, and market requires more and more stricter to properties of product, and product category is variation more also.The bench test of generally adopting in the replacement industry that adopts at present is synchro converter ring abrasion durability-testing machines, can not reflect the rubbing characteristics of synchronous ring in real work comparatively accurately.The inertia of each gear is different in the wheel box, and the friction factor of test also should be different, and the driving shaft of testing machine and motor can not break away from the trial, and inertia is bigger, is a kind of pressure abrasion test.Therefore, existing testing machine need further improve.
Summary of the invention
The object of the invention is through the improvement to the abrasion durability-testing machines, and solve the technical matters that existing synchro converter ring durability-testing machines exists: 1. the driving shaft of testing machine can break away from and combine with motor power rapidly.2. the inertia on the testing machine driving shaft can change.3. the control system of testing machine is carried out corresponding improvement.
Modified synchro converter ring abrasion durability-testing machines of the present invention comprises: stand and base A, electric machine assembly B; Drive rod assembly C, box part D, dynamometry axle and cylinder assembly E; Cylinder supports assembly F, switch board G, oil temperature heating Control Component H and data processing centre (DPC).
Said drive rod assembly C; Comprise: belt pulley 2 links to each other with driving shaft 3, and driving shaft 3 one sides connect inertial flywheel 1, and electromagnetic clutch 4 is housed on the driving shaft 3; Driving shaft 3 is divided into two sections that can break away from, is connected to electric-control system on the electromagnetic clutch 4 and links to each other with switch board.
All the other said each parts are identical with original testing machine composition and annexation.Described original testing machine patent first please number be 201110413825.2.
The method of operating of modified synchro converter ring abrasion durability-testing machines of the present invention is: at first according to the synchronous ring that will make an experiment, the inertial flywheel of selecting to be complementary is installed on the testing machine, the inertia of engaged wheel during the real work of simulation wheel box.Usually each grade follower gear in the wheel box varies in size, and moment of inertia is also inequality, according to 1 grade, 2 grades, 3 grades, 4 grades, 5 grades order; The moment of inertia of the follower gear of coupling reduces successively; For example: * * * car, 2 grades of gear inertias are 0.07006kg ㎡, 3 grades is 0.01115 kg ㎡; Afterwards according to the requirement of when test, the following parameter (condition) of testing machine is provided with the synchronous ring condition of work: time, frequency, test number (TN) that gear rotational speed, oil product temperature, synchronous ring contact with the cone of gears, adjust electric control system; Can make an experiment according to the identical method of original testing machine afterwards.
The principle that modified synchro converter ring abrasion durability-testing machines of the present invention increases function is: after the gear cone is got up by driven by motor according to the rotating speed of setting; The clutch coupling outage realizes that driving shaft separates with motor, and cylinder is exerted pressure to synchronous ring simultaneously and made the synchronous ring taper hole combine friction with the cone of gears; After driving shaft and motor stopped, cylinder stopped to exert pressure, and electromagnetic clutch combines electric motor starting through making driving shaft with motor; Periodic duty so repeatedly.
The advantage of modified synchro converter ring abrasion durability-testing machines of the present invention is: through the improvement to synchro converter ring abrasion durability-testing machines; Can realize that driving shaft and motor power break away from; Simultaneously can change flywheel inertia; Performance in the real imitation wheel box during actual gear shift not only can satisfy original synchronous ring wear hardness test, also can satisfy the different inertia requirements to the test of synchronous ring monomer simultaneously; The performance of authentic testing synchronous ring under actual inertia operating mode made evaluation accurately to synchronous ring.
