Problems solved by technology

Therefore, it is difficult to completely simulate the manipulation actions of the driver of the whole vehicle in terms of manipulation actions, and it is also impossible to subjectively evaluate the shift system and clutch system on the bench
At present, there are similar static and dynamic tests of the gear shift system and clutch system applied to the vehicle state, but there is no application of this technology on the bench for the subjective evaluation and static test of the gear shift system and clutch system.

Embodiment 1

[0065] This embodiment is aimed at when the test bench of the present invention is used for subjective evaluation of a gear shift system and a clutch system. Further implementation measures are as follows:

[0066] Such as Figure 12 As shown, on the basis of completing the installation of the test bench according to the steps already described above, it is further necessary to install the shift rod ball handle 80 at the position of the ball head 71 of the shift rod 70 of the shifter assembly 3, but no further steps are required. Install any sensors and data acquisition systems.

[0067] When performing subjective evaluation, the evaluator sits on the seat assembly 2, manually manipulates the shift lever ball handle 80 on the shifter according to the test requirements, and steps on the clutch pedal (75) on the clutch pedal assembly 5 with his feet. for subjective evaluation.

Embodiment 2

[0069] This embodiment is aimed at when the test bench of the present invention is used for static testing of a gear shift system and a clutch system. Further implementation measures are as follows:

[0070] On the basis of completing the installation of the test bench according to the steps already described above, further, the test bench also includes the installation of a shift lever force sensor 13, a three-plane position sensor 14, a pedal force sensor 15, a linear displacement sensor 16 and a data acquisition system.

[0071] Such as Figure 4 , Figure 13 As shown, the shift rod force sensor 13 is installed on the ball head 71 of the shift rod 70 of the shifter assembly 3 for measuring the force signal of the ball head 71 of the shift rod 70 . The three-plane position sensor 14 is installed on the second adapter 43 of the fixed bracket 9 through the sensor mounting bracket 73 . The three-plane position sensor 14 is mechanically connected with the shift lever 70 of th...

Abstract

The invention provides a test bench for subjective evaluation and stationary testing of a vehicle, which is used for testing a manual or automatic shifting system and a clutch system of the vehicle. The test bench comprises a floor, wherein to-be-tested parts and fixing toolings of the to-be-tested parts are arranged on the floor; the to-be-tested parts comprise a seat assembly, a shifter assembly, a stay line assembly, a gearbox assembly and a clutch system; the fixing toolings of the to-be-tested parts are used for respectively fixing the corresponding to-be-tested parts on the floor according to the actual layout states of the vehicle, and simulating the operation of a driver under the driving condition of whole vehicle, so as to complete the subjective evaluation and stationary property testing of the to-be-tested parts. The test bench has the advantages that the shifting system and the clutch system under the condition of whole vehicle can be truly simulated on the test bench, and the parameters of the measuring system in the research, development and verification phase, such as shift selecting force, shifting force, shift selecting travel, shifting travel, clutch pedal force and clutch pedal travel, can be measured; the test bench is especially suitable for the preliminary development and verification phase before the prototype of the whole vehicle is produced.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a test bench used for subjective evaluation and static testing of a gear shifting system and a clutch system of a vehicle. Background technique [0002] In recent years, the technical level of China's self-owned brand vehicles has made rapid development and progress, but there is still a certain gap between the shift performance and shift quality of vehicles and international vehicle brands. [0003] As the important components of the vehicle, the gear shift system and the clutch system directly affect the gear shift quality and driving experience of the vehicle. Therefore, in the product development stage, especially the early stage of product development before the vehicle prototype comes out, a test bench that can truly and effectively measure the static shift performance of the shift system and clutch system is particularly important. [0004] At this stage, there ar...
