Problems solved by technology

[0008] In addition, the rollers 116 and 118 will be gradually worn due to the linear movement and rolling of the shift rod 110, so that the distance between the rollers 116 and 118 and the shift rod 110 will expand.
This spacing creates a gap between the shift rod 110 and the support assembly, and since the increasing gap cannot be removed, the gap between the two components cannot be compensated.

Embodiment Construction

[0026] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] figure 2 shows a front view of a transmission gear mechanism shift rod according to an embodiment of the present invention, and image 3 is along figure 2 Sectional view taken along the midline A-A. because figure 2 The upper and lower parts of the sectional view are symmetrical, so only the components in the upper part of the line A-A are shown in image 3 , and it should be recognized that the omitted lower part is consistent with this upper part.

[0028] The transmission gear shift rod supporting assembly of the preferred embodiment of the present invention includes a casing 20 fixed on the vehicle body 18 by bolts 12 , a washer 14 and a nut 16 and a ball box 24 connected to the casing 20 by screws 22 . A shift rod 26 of the transmission gear shift mechanism passes through holes 20a and 24a formed in the housing 20 and bal...

Abstract

Disclosed is a shift rod support assembly for a transmission gear shift mechanism comprising a housing fixed to a vehicle body and including a hole through which a shift rod passes; a ball case including a fixed unit that is fixedly mounted to the housing and has a hole through which the shift rod passes, and having a protrusion portion extending toward an inner area of the housing from the fixed unit and a plurality of ball insertion holes; a plurality of balls, each provided in one of the ball insertion holes in a state of contacting the shift rod, the balls rotating as the shift rod undergoes rectilinear and rotational motion; rollers provided in a space formed by the housing and the ball case, the rollers contacting and rotating together with the balls; and play adjustment members for adjusting play between the rollers and the balls by manipulating positioning of the rollers relative to the housing and the ball case.

Description

technical field [0001] The present invention relates to a transmission gear shift mechanism, in particular to a shift rod support assembly of a transmission gear shift mechanism, wherein the gap between the shift rod and the support assembly is easy to adjust, and at the same time can reduce the resistance in the selection operation of the shift lever. This reduces noise during operation, improves the overall durability and smooth operation of the transmission gear shifting mechanism. Background technique [0002] Depending on the type of transmission and its positioning, there are a variety of transmission gear shifting mechanisms for controlling manual shift transmissions. The two main categories of such transmission gear shifters are direct-operated and remote-operated. In remote-operated transmission gear shifters, the shift lever is separated from the transmission by a significant distance, and there is a shift rod or cable connecting the two components to allow intera...
