手动换挡机构耐久试验装置 

Durability test device for manual shift mechanism

一诺试验机以及研发设计团队生产了一种手动换挡机构耐久试验装置，包括控制柜、固定支架和气源以及控制器，所述控制柜上设有气动滑台，在气动滑台的滑块上设有三位气缸，所述三位气缸的活塞杆端部与设在固定支架上换挡机构的换挡杆顶部之间相连，所述控制器设在控制柜内并控制气源、气动滑台以及三位气缸工作。通过该装置的三位气缸和气动滑台相配合，可进行所有档位的耐久试验，变速箱为负载，能准确模拟选换挡机构的实际受力大小，保证试验结果的准确性。

     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系列试验台是按手动换档操纵机构耐久性试验标准等相关行业标准要求，对选换档操纵机构进行耐久测试，对检测结果进行产品合格与否判断。
