Embodiment Construction
[0027] The invention provides a reverse gear locking mechanism, such as figure 2 , Figure 4 and Figure 5 As shown, it is the vertical raised portion 21 of the shifter cover, and the vertical raised portion 21 includes: a first flange 211, a second flange 212, and a position between the first flange 211 and the second flange 212. The one-way body 22 between; the one-way body 22 is movably connected with the first flange 211 and the second flange 212 through the rotating shaft 221; the first flange 211 and / or the second flange 212 are opposite to the one-way body 22 There is a limit protrusion 213 on the surface; the surface of the one-way body 22 facing the stop bar 23 has a recess 222 that matches the limit protrusion 213; when the stop bar 23 is in the locked position, the inner wall of the recess 222 is against the stop Protrusion 213 ; when the gear lever 23 exits the reverse gear, the one-way body 22 rotates around the rotating shaft 221 along the direction that the r...

The invention discloses a reverse gear locking mechanism, and a shifter cover plate and a shifter using the same, which relates to the technical field of automotive transmission control, and aims to solve the problems that in the prior art, when a reverse gear is retreated, a large friction force is generated between a handle and a vertical raised part of a cover plate, so that a situation that noises are generated, and the reverse gear locking mechanism is short in service life and low in reliability, and the like is caused. The reverse gear locking mechanism is a vertical raised part of a shifter cover plate, the vertical raised part comprises a first flange, a second flange and a unidirectional body, wherein the unidirectional body is arranged between the first flange and the second flange; the unidirectional body is movably connected with the first flange and the second flange through a rotating shaft; the surfaces of the first flange and / or the second flange opposite to the unidirectional body are respectively provided with a limiting bulge; the surface of the unidirectional body facing a stop lever is provided with a pit matched with the limiting bulge; when the stop lever is located at the locking position, the inner wall of the pit is pressed against the limiting bulge; and when the stop lever is retreated from the reverse gear, the unidirectional body rotates around the rotating shaft along the direction that the pit deviates from the limiting bulge.
Description
technical field [0001] The invention relates to the technical field of automobile transmission manipulation, in particular to a reverse gear locking mechanism, a shifter cover plate and a shifter using the same. Background technique [0002] The shifter in a 6-speed manual transmission car usually needs to be equipped with a reverse gear locking mechanism to prevent the driver from accidentally engaging the reverse gear when the driver wants to put the gear into a forward gear (such as 1st gear and 2nd gear) that is close to the reverse gear. block. [0003] figure 1 It is a partial structural schematic diagram of the reverse gear locking mechanism in an existing 6-speed manual transmission car. The reverse gear locking mechanism is a vertical raised portion 13 of the shifter cover, which is vertical and integrally formed with the horizontal plate 14 of the shifter cover. The top surface of the vertical raised portion 13 is arc-shaped, the highest point A of the arc-shape...
