However, the groove structure of the experimental device is a continuous tooth shape with a fixed inclination angle, which is simplified when calculating the shift stroke and shift force. In order to improve the comfort and smoothness of shifting, the groove structure will be designed as continuous Undulating arc surface grooves, so the shift force evaluation method cannot be adapted to the improved shift mechanism

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings to facilitate a clearer understanding of the present invention, but they do not limit the present invention.
[0021] like Figure 1~4 As shown, a gearshift mechanism used for automobile simulation tests includes a ball head 1 and a shift lever 2. The shift lever 2 includes an inner rod 21 and a sleeve rod 22. The lower end of the inner rod 21 is threaded with the upper end of the sleeve rod 22. Connection, the upper end of the inner rod 21 is fixedly connected with the ball head 1, the middle part of the sleeve rod 22 is hinged with the rotating bracket 3 through the horizontal rotating shaft 11, the rotating bracket 3 is a frame structure, and the rotating bracket 3 is hinged with the side plate 5 through the longitudinal rotating shaft 12, and the side plate The lower end of 5 is fixedly connected with the base 4, and the side plate 5 is two rectangular plate...

The invention discloses a gear shifting mechanism for automobile simulation test, which comprises a ball head and a gear shifting rod. The ball head is fixedly connected with the upper end of the gearshifting rod. The middle of the gear shifting rod is articulated with a rotating support through a transverse rotating member. The rotating support is articulated with a side plate through a longitudinal rotating member. The lower end of the side plate is fixedly connected with a base. A continuous groove is arranged in the upper surface of the base, and the outer contour of the groove is a continuous arc. The lower end of the gear shifting rod is matched with a movable pressing block in an axial relative motion manner. The bottom of the movable pressing block abuts against the groove. The invention further provides a method for verification by using the gear shifting mechanism, including the following steps: (1) adjusting the gear shifting stroke to a target value; (2) adjusting the gearshifting force to a target value, (3) performing rod shifting operation and evaluation, and (4) carrying out redesign and verification. The gear shifting force and the gear shifting stroke can be verified at the same time. The groove is a continuous circular arc, which enhances the comfort of gear shifting.
Description
technical field [0001] The invention relates to a shift mechanism, in particular to a method for simulating and verifying a shift mechanism. Background technique [0002] The shifting mechanism of a car is an operating mechanism frequently used by drivers during driving. The length of the shifting stroke and the magnitude of the shifting force directly affect the feeling of driving comfort. However, in the early stage of vehicle development, there is often a lack of convenient and fast evaluation methods for physical evaluation. If the shift mechanism is verified on a real vehicle, a complete set of shift mechanism needs to be trial-produced first, and then installed on the real vehicle. The entire installation process is time-consuming and laborious, and the economy is poor; The gear shifting force cannot be adjusted in real time. If the stroke or force is changed, it needs to be re-produced and verified. [0003] Chinese patent CN103575447B discloses an experimental devi...
