Abstract

The invention discloses a hand-operated gearbox gearshift performance testing apparatus which includes a first sensor, a second sensor, a third sensor, a data collector, and a data processing unit. The first sensor is arranged in the position of a gearshift level. The second sensor is used for detecting the displacement amount of the gearshift level in the gear-selection and gear-shift process. The third sensor is used for detecting the displacement amount of a gearshift fork in the gear-shift process. The data collector is connected to the first sensor, the second sensor, and the third sensor. The data processing unit is connected to the data collector. The hand-operated gearbox gearshift performance testing apparatus can realize the test of the hand-operated gearbox gearshift performance, and effectively evaluates the influence brought by customer complaints caused by the gearshift problem of the hand-operated gearbox. Through professional manipulation, the stuck and unsmooth problems in the gear-shift process are simulated, and design defects of a gearshift mechanism or a gearbox body are pertinently solved.

Description

Technical field [0001] The invention belongs to the technical field of testing. Specifically, the invention relates to a manual gearbox shifting performance test device. Background technique [0002] With the development of the automobile industry, the power and handling of automobiles are increasingly valued by customers. In particular, the comfort and flexibility of manual gearbox shift control has become an important symbol of the advancement of automobile technology. Sense, the clarity of gear entry, and the sound of gear shift entry are all important manifestations of the advanced level of an automobile industry. [0003] However, if in the process of research and development of the entire automobile machine, customers complain about the gear shifting problem of the gearbox, it will be fatal to the automobile company, because with the rapid development of the automobile industry, automobile products are continuously enriched. Technology is also maturing, so that the competiti...
