Description

A kind of gear-shifting knob

Technical field

A kind of auto-parts are the utility model is related to, more specifically to a kind of gear-shifting knob.

Background technology

When modern automatic catch automobile travels, driver need to only control accelerator pedal, and computer is by sensor detection To engine air throttle aperture and GES analyzed, automatically control speed change or speed changer is changed to different gear works Make.

As shown in figure 1, a kind of automatic catch vehicle gearshift assembly, includes gear level 1 and the handball on the top of gear level 1, changes Pin 1 is made up of gearshift outer bar 1b and gearshift interior bar 1a, and gearshift outer bar 1b is coaxially disposed with gearshift interior bar 1a and the interior bar 1a that shifts gears Nesting is arranged at gearshift outer bar 1b centers；Handball grafting is arranged on the top of gear level 1, is provided perpendicular to shift gears in handball The button passage 42 of the axis direction of bar 1, slid in button passage 42 and be provided with key support 3, the one end of key support 3 is provided with Button 2, the other end are connected to gearshift interior bar 1a tops, and the contact surface 31 of key support 3 and the interior bar 1a that shifts gears is inclined to set, changed Gear interior bar 1a tops abut against with contact surface 31, and key support 3 slides in button passage 42, and the contact surface 31 being obliquely installed makes to change Gear interior bar 1a is moved down, and operator, which extrudes button 2, can carry out gear shift operation.

In the prior art, gearshift interior bar 1a is that metal material is made and key support 3 is plastic products, and handball was using The interior bar 1a that shifted gears in journey is slid on contact surface 31, and for a long time using contact surface 31 can be caused to wear, contact surface 31 is pressed after wearing Gap is formed between key support 3 and gearshift interior bar 1a, handball, which rocks, in vehicle traveling process can produce noise, and prior art is deposited In improvements.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of gear-shifting knob, the gearshift hand Ball between key support and button by setting second spring, when slowing down automobile gear shift, in key support contact surface and gearshift The rigidity abutting on bar top, and then slow down the abrasion of contact surface, extend handball service life.

To achieve the above object, the utility model provides following technical scheme：A kind of gear-shifting knob, including handball bone Frame, button passage is offered in the handball skeleton, in the button passage sliding be provided with key support, the key support Side is provided with button, and the key support is provided with the first bullet to be stretched along key support glide direction away from button side Spring, second spring is connected between the key support and button, second spring telescopic direction is identical with button glide direction, institute State the Access Division being provided between button and button channel side wall for limiting button along button channel direction displacement.

By using above-mentioned technical proposal, when automobile gear shift operates, button compression second spring, second spring is promoted and pressed Key support abuts gearshift interior bar top and moves down it in button passage intrinsic displacement, the contact surface of key support, works as button While support applies active force to gearshift interior bar, gearshift interior bar can apply reaction force to key support, and second spring is set Put and enable key support to carry out a certain amount of left and right skew when abutting gearshift interior bar and moving downward, play certain buffering Effect, the rigidity for slowing down contact surface with interior bar top of shifting gears abuts, and then slows down the abrasion of contact surface, extends handball and uses the longevity Life；When gearshift terminates, it is necessary to discharge pressure of the key support to interior bar of shifting gears, key support is in the presence of the first spring force Reset, to discharge pressure of the key support to interior bar of shifting gears, the first spring promotes key support and button to reset, sets clamping Relative position of the button in button passage is fixed in portion, avoids button from ejecting button passage with second spring.

The utility model is further arranged to：Be provided with fixing body in the button passage, the fixing body be provided with The stroke passage that button passage is connected, the stroke passage coordinate with button sliding, and the wedging position is in fixing body with pressing Between key.

By using above-mentioned technical proposal, button displacement back and forth in the stroke passage in fixing body, Access Division is set With on the fixing body of button passage split settings, avoiding the processing of handball from installing.

The utility model is further arranged to：The Access Division includes being correspondingly arranged on button and fixing body in mutual The first annular boss and the second annular boss of occlusion.

By using above-mentioned technical proposal, the structure of first annular boss and the second annular boss is simple, and convenient installation connects Connect, overall structure in a ring, block and there is larger contact area afterwards, be advantageous to the stability of increase card sum.

The utility model is further arranged to：The button is in hollow setting, and the key support includes to be slided with button Dynamic the first vertical plane coordinated, it is within the cavity formed with cavity, the second spring between the first vertical plane and button.

By using above-mentioned technical proposal, second spring is arranged in cavity, sufficiently make use of the knot of handball button Structure, simplify the space inside handball, make handball overall structure compacter.

The utility model is further arranged to：The key support also includes the second vertical plane, second vertical plane Side is provided for the positive stop lug boss of the spring of inlay card first.

By using above-mentioned technical proposal, in actual use, the pressing force suffered by key support will not be complete Perpendicular to the glide direction of key support, positive stop lug boss can play certain positioning and guiding effect to the first spring, first The first spring is avoided to depart from key support during spring deformation.

The utility model is further arranged to：The stroke passage is additionally provided with support ring back to button one end, described to press Key support is set up in support ring.

By using above-mentioned technical proposal, the setting of support ring is played a part of supporting key support so that automobile gear shift When, button and key support being capable of more smoothly displacements back and forth.

In summary, the utility model has the advantages that：

The gear-shifting knob structure is simple, is easily installed processing, when reducing automobile gear shift handball internals and gear level it Between rigidity abutting, and then reduce frictional dissipation, extend the service life of handball, slow down handball using being produced after a period of time Raw the problem of rocking noise.
