Embodiment Construction
[0018] A wheel fatigue test bench loading device such as figure 1 As shown, it includes flywheel 1, wheel shaft 3, wheel fork 4, loading cylinder 5, column 6, support seat 7, base 8, emergency brake 9, bracket 10, large coupling 11, reducer 12, small coupling Device 13 and drag motor 14.
[0019] The base 8 is the carrier of this embodiment. The speed reducer 12 and the flywheel 1 are all installed on the upper surface of the base 8 table. The flywheel 1 is fixedly installed on the output shaft of the speed reducer 12 by a key, and is fixed on the upper surface of the base 8 table by a bracket 10 . The support seat 7 is installed on the lower surface of the base 8 table, and is located on the center line of the base length direction. One end of the supporting base 7 supporting plate is hinged with the column 6 by a pin. The upper end of the column 6 passes through the oil cylinder installation groove on the table top of the base 8, and is connected with the wheel fork 4 ab...

The utility model relates to a loading device of a wheel fatigue test bench. Both a reducer and a flywheel are installed on the upper surface of a base table. The flywheel is fixedly installed on the output shaft of the reducer. The support seat is installed on the lower surface of the base table and is located on the center line of the base in the length direction. One end of the support plate of the support seat is hinged with the column. The upper end of the column passes through the oil cylinder mounting groove on the base table, and is connected with the wheel fork above the base table through a copper sleeve. Wheel axle is fixed on the top of described wheel fork. The center of the wheel shaft is at the same height as the center of the flywheel. The loading oil cylinder is located in the installation groove of the oil cylinder, and one end is hinged with the lug in the middle of the column through a pin. An emergency brake is located at the circumferential surface on the other side of the flywheel to apply emergency braking to the flywheel. The invention adopts the principle of leverage to realize the loading on the test machine wheel, and has simple structure and convenient use and maintenance.
Description
technical field [0001] The invention relates to a wheel fatigue test, in particular to a loading device for a wheel fatigue test bench. Background technique [0002] In order to evaluate the life of the aircraft wheel, the in-plant test requires the fatigue rolling test of the wheel on the fatigue test bench. According to the principle of relativity, during the wheel rolling fatigue test, the flywheel is used instead of the airport runway, and the wheel is installed on the loading head of the test bench. When the flywheel surface linear velocity reaches the rolling speed required for the test, the test bench is operated Loading head, so that the tested wheel is tightly pressed on the surface of the flywheel to run synchronously; the pressing load is equivalent to the load imposed on the wheel by the aircraft, and is provided by the hydraulic system; the load size can be automatically or Manual control; finally measure, record and display relevant data by relevant detection ...
