Gear shift performance test device and shift performance test method for automobile power system

Abstract

The present invention provides an automobile power system shift performance test device applied to the technical field of power system performance test. The present invention provides an automobile power system shift performance test method. A test substrate (1) of the automobile power system shift performance test device is provided with a gearbox mounting bracket (2), a shift mechanism installation bracket (3) and a servo drive support (4), a servo motor (7) on the servo drive support (4) is connected with one end of an execution mechanism (8), the servo motor (7) is provided with a pull lever displacement sensor (9), the other end of the execution mechanism (8) is provided with a pull-press force sensor (10), and the pull-press force sensor (10) is connected with a shift casing pipe (11). The automobile power system shift performance test device can conveniently and accurately simulate the state of the whole vehicle to allow the vehicle selection and shift performance test operationto be simple and improve the product shift quality.

Description

technical field [0001] The invention belongs to the technical field of power system performance testing, and more specifically relates to a gear shifting performance testing device of an automobile power system, and also relates to a gear shifting performance testing method of an automobile power system. Background technique [0002] The performance of the vehicle's shifting system directly affects the driver's operational perception, which is commonly known as the shift quality. The shift quality is a comfortable operating perception of the force level, clarity, and shifting feeling during the shifting process. (such as the size of force, suction feeling, smoothness, clarity, stroke, man-machine, etc.), it is the most basic and important performance in a car, and it is also one of the vehicle performances that users pay most attention to and are most likely to perceive. The performance of each performance in the shift quality determines the direction of the shift quality, s...

Problems solved by technology

At present, in the field of automobile manufacturing, due to the inability to intervene in the performance test of the shift system in the early stage of design and development, the test can only be carried out after the prototype car comes out, which increases the project cycle and the cost of design changes; Disassembly and assembly brings great inconvenience, and the test cycle is also longer

With the current shortening of the development cycle of automobile projects, it is a magic weapon for major automobile manufacturers to occupy the market by launching products with better quality, higher efficiency and more attractiveness to the market. Therefore, the development cycle of vehicle models will become shorter and shorter (based on platform-based development). Due to the limitation that the whole vehicle data acquisition system can only test the whole vehicle, coupled with the continuous updating of models, the matching of the gear selection system will become more frequent, so there is an urgent need for an efficient and reliable gear selection performance test device
