手動換擋機構耐久試驗裝置 

Durability test device for manual shift mechanism

一諾試驗機以及研發設計團隊了一種手動換擋機構耐久試驗裝置，包括控制柜、固定支架和氣源以及控制器，所述控制柜上設有氣動滑臺，在氣動滑臺的滑塊上設有三位氣缸，所述三位氣缸的活塞桿端部與設在固定支架上換擋機構的換擋桿頂部之間相連，所述控制器設在控制柜內并控制氣源、氣動滑臺以及三位氣缸工作。通過該裝置的三位氣缸和氣動滑臺相配合，可進行所有檔位的耐久試驗，變速箱為負載，能準確模擬選換擋機構的實際受力大小，保證試驗結果的準確性。

     The utility model discloses a durability test device for a manual shift mechanism by YiNuo Testting factory, which comprises a control box, a fixing support, an air source and a controller. A pneumatic slipway is arranged on the control box; a three-position cylinder is arranged on a sliding block of the pneumatic slipway; the end part of a piston rod of the three-position cylinder is connected with the top part of a shift rod of a shift mechanism on the fixing support; and the controller is arranged inside the control box and controls operation of the air source, the pneumatic slipway and the three-position cylinder. Through match between the three-position cylinder and the pneumatic slipway, durability test on all gears can be carried out, a gearbox is a load, the actual force-bearing magnitude of the shift mechanism can be accurately simulated, and accuracy of the test result can be ensured.

HDP系列試驗臺是按手動換檔操縱機構耐久性試驗標準等相關行業標準要求，對選換檔操縱機構進行耐久測試，對檢測結果進行產品合格與否判斷。
