Abstract

The invention discloses an automobile shift handle ball. A handle frame (2) is arranged in the handle body (1). A pressure plate (3) is installed on the top of the handle frame (2) through bolts. The position indicator (4) is covered, and the gear indicator (4) is installed on the top of the handle body (1). On the handle frame (2), there is an assembly hole through the bottom surface along its axis line. The assembly hole has a threaded section (2a) and a plain hole section (2b). The upper end of the threaded section (2a) is a tapered thread with a small top and a large bottom, and the rest is a straight thread. In the present invention, by changing the upper end of the threaded section of the assembly hole in the handle frame into a tapered thread, the gear indicator can be positioned at the alignment position, and the handle ball will not loosen. On the one hand, the reliability of the handle ball installation is ensured. On the other hand, the assembly process is simplified and the production efficiency is greatly improved.

Description

Automobile shift handle ball

Technical field

The present invention relates to a kind of automobile component, particularly the shift handle ball on the automobile.

Background technique

Automobile shift handle ball is installed on the upper end of gear level, works to make things convenient for driver's operation and indicates shifting state.The structure of existing shift handle ball is as shown in Figure 3, in handle body 1, is provided with handle skeleton 2, and the top of this handle skeleton 2 is equipped with pressing plate 3 through bolt, and pressing plate 3 is covered by gear direction board 4, and gear direction board 4 is installed on the top of handle body 1.Its shaft axis has the pilot hole that connects its bottom surface in said handle skeleton 2 upper edges, and this pilot hole is made up of thread section 2a and unthreaded hole section 2b from the top down, and the internal diameter of thread section 2a is slightly littler than the internal diameter of unthreaded hole section 2b.When installing, the upper end of gear level is screwed in the pilot hole of handle skeleton, the outside thread on the gear level is matched with the thread section 2a of pilot hole.Because thread section 2a is a straight thread, the effect of no pretension locking, gear direction board 4 can't align when causing handle skeleton 2 and gear level to tighten easily, and perhaps gear direction board 4 is when aligned position, and handle ball is in loosening state.Therefore, before installation, need earlier, screw the position that aligns to gear direction board 4 to gear level and handle ball, treat to fix after the glue solidifies at gear level thread head gluing.Above-mentioned fit has increased operation on the one hand, has reduced manufacturing efficiency; On the other hand, do not solidify the front hand grip ball at glue and still can't locate, but this moment the people position of handle ball for a change still, reliability is relatively poor.In addition, if gear level screws in tension, the upper-end surface of gear level is exerted pressure excessive to the inner roof wall of pilot hole, and the influence that is stressed of the construction bolt of pressing plate is backed down the gear direction board easily, causes the gear direction board to become flexible or comes off.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of automobile shift handle ball, and to guarantee the gear direction board when the aligned position, handle ball can not become flexible.

Technological scheme of the present invention is following: a kind of automobile shift handle ball; Comprise handle body, handle skeleton, pressing plate and gear direction board, in handle body, be provided with the handle skeleton, the top of this handle skeleton is equipped with pressing plate through bolt; Pressing plate is covered by the gear direction board; And the gear direction board is installed on the top of handle body, and its shaft axis has the pilot hole that connects its bottom surface in said handle skeleton upper edge, and this pilot hole has thread section and unthreaded hole section; Its key is: the upper end of said thread section is up-small and down-big tapered thread, and remaining part is a straight thread.

The present invention changes the upper end of pilot hole thread section in the handle skeleton into tapered thread, and the threaded end to gear level carries out adaptation simultaneously, like this when gear level screws in the tapered thread part of handle skeleton pilot hole; Because tapered thread has the effect of pretension locking; Can make the gear direction board rest on the aligned position location, and handle ball can not be become flexible, and has both guaranteed the reliability that handle ball is installed; Simplify assembly process again, improved manufacturing efficiency greatly.

The tapering of said thread section upper end tapered thread is 12-20 °, and the gradient of tapered thread part is bigger, and pretightening force is also bigger, can further improve the reliability that handle ball is located on gear level, prevents that the gear direction board is loosening to handle ball generation in correct time.The tapering of tapered thread is too small, and pretightening force is too big, turns the gear level effort; The tapering of tapered thread is excessive, and pretightening force is little, can influence the reliability of handle ball location.

Above the tapered thread of said thread section upper end, have the aperture section that is attached thereto, the internal diameter of this aperture section is less than the internal diameter at the minimum place of thread section.The upper end of gear level screws in the pilot hole of handle skeleton; Because the existence of aperture section is arranged; Have the gap between the inner roof wall of the pilot hole on the upper-end surface of gear level and the handle skeleton, even gear level screws in tension, the upper-end surface of gear level can not contact with the inner roof wall of pilot hole yet; Effective like this gear level of having avoided is exerted pressure to the inner roof wall of pilot hole, and the gear direction board is backed down in the construction bolt that the has prevented pressing plate influence that is stressed.

Bilateral symmetry on said handle skeleton top is provided with balancing weight, and this balancing weight is wrapped in the handle body.Balancing weight plays a part to increase handle ball weight, and feel is better when making driver's gear shift operation.

Beneficial effect: the present invention changes tapered thread into through the upper end with pilot hole thread section in the handle skeleton; The gear direction board is rested on the aligned position locate, and handle ball can not be become flexible, guarantee the reliability that handle ball is installed on the one hand; On the other hand; Simplified assembly process, improved manufacturing efficiency greatly, the while has effectively been avoided the gear direction board to become flexible or has come off.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further:

Like Fig. 1, shown in Figure 2, the present invention is made up of handle body 1, handle skeleton 2, pressing plate 3, gear direction board 4 and balancing weight 5, and wherein the top of handle body 1 is similar to sphere, and the bottom of handle body 1 is up big and down small taper.Handle skeleton 2 is set in handle body 1, and the lower ends downward of this handle skeleton 2 is stretched out the bottom surface of handle body 1.Top at said handle body 1 has groove, and pressing plate 3 is installed in this groove, and the middle part of pressing plate 3 fixes through the bolt that wears from top to bottom and the top of handle skeleton 2.Gear direction board 4 is installed at notch place in handle body 1 top groove, and this gear direction board 4 is a spheric structure, and pressing plate 3 is covered, and the upper surface of gear direction board 4 is provided with the gear cue mark.
