In the utility model, the mechanism downshift switch has the advantages of: adopting fewer components, reducing the cost, having convenient assembly, and being detachable and easy to be changed as a spring component is utilized.

Description

Mechanical kickdown switch in the efp

Technical field

The utility model relates to Motor Vehicle associate member field, particularly relates to a kind of efp internal mechanical downshift switch.

Background technique

In having the vehicle of automatic transmission, gas pedal internal mechanical downshift switch gives the realizable feedback that the driver has been triggered about the internal mechanical downshift switch by the steering force rising of jump type.Prior art adopts built-in mostly, regulates the stroke of mechanical kickdown switch by the elastic force of tinsel.

The model utility content

The utility model provides the mechanical kickdown switch in a kind of efp, comprise: housing, pivoted arm, spring and protrusion means, wherein, described housing is installed in the pedal arm of described efp, it has the side to internal contraction, enclosure interior has pivoted arm and the spring between pivoted arm, and described protrusion means has and the corresponding curve bath of described pivoted arm upper end shape, and pivoted arm can rotate along described curve bath, outside protrusion means is subjected to during force compresses, protrusion means driven rotary arm pressure spring moves to enclosure interior, and when described external force disappeared, spring struts pivoted arm made pivoted arm and protrusion means recover the home position.

By technique scheme, advantage and beneficial effect that mechanical kickdown switch of the present utility model has are:

(1) adopts less part number, reduce cost, be convenient to assembling.

(2) owing to adopt spring element, detachably, be easy to change.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

With reference to figure 1-4, the utility model is about a kind of efp internal mechanical downshift switch.Described mechanical kickdown switch is installed within the pedal arm 6 of efp.The mechanical kickdown switch comprises protrusion means 1, pivoted arm 2, spring 3 and housing 4.Housing 4 inside comprise pivoted arm 2 and spring 3.Spring 3 is between pivoted arm 2.Housing 4 has the side 401 to internal contraction, because the past more inner space of housing is more little, causes pivoted arm when stressed pressing down, and pivoted arm inwardly rotates, and pressure spring.Pivoted arm 2 upper end connection bump mechanisms 1.Protrusion means 1 has arc groove 101, and described arc groove is corresponding with the curved upper surface of pivoted arm.Protrusion means 1 can rotate pivoted arm 2 along arc groove 101 for pivoted arm 2 provides fulcrum.

When gas pedal do not depress, when being in initial position, protrusion means 1, pivoted arm 2 and spring 3 are in original state.This moment, protrusion means 1 protruded from pedal arm 6.The positive pressure that spring 3 produces has increased the frictional force of pivoted arm 2 with housing 4, and spring 3 and pivoted arm 2 are remained static.Pivoted arm 2 produces and acts on the tension force to both sides of protrusion means 1 because of the elastic force of spring, thereby makes protrusion means 1 keep static.

Press down along with gas pedal is stressed, when protrusion means 1 contacted with efp housing 7, mechanical kickdown switch 5 began to work.Protrusion means 1 stressed inside compression this moment, driven rotary arm 2 moves in housing 4.Because the enclosure interior space is more and more littler, so pivoted arm 2 also produces inside rotatablely moving.Because there is positive pressure in spring 3, there is frictional force in pivoted arm 2 with housing 4, because under the original state, housing 4 inner space sudden change formulas reduce, pivoted arm 2 need overcome very large frictional force and could work.Jump type on this steering force rises to provide and feeds back to the driver, reminds driver pedal will arrive range.When the driver continued pushes pedals, active force slowly reduced, and reached range up to pedal.At this moment, the pressure that protrusion means 1 is produced because of efp housing 7 is moved to the inside of housing 4, and protrusion means 1 promotes pivoted arm 2 and arrives predetermined stroke.After the driver decontroled gas pedal, spring 3 produced and protrusion means 1 moving direction opposite effect power, and under the condition that does not have the external force effect, protrusion means 1, pivoted arm 2 and spring 3 automatically restore to original state.

Claims (1)

1. the mechanical kickdown switch in the efp is characterized in that: comprising: housing (4), and pivoted arm (2), spring (3) and protrusion means (1),

Wherein, described housing is installed in the pedal arm (6) of described efp, it has the side (401) to internal contraction, enclosure interior has pivoted arm (2) and the spring between pivoted arm (3), described protrusion means (1) has and the corresponding curve bath (101) of described pivoted arm (2) upper end shape, described pivoted arm (2) can rotate along described curve bath

Outside protrusion means (1) is subjected to during force compresses, protrusion means (1) driven rotary arm (2) pressure spring (3) is to housing (4) internal motion, when described external force disappeared, spring (3) struts pivoted arm (2) made pivoted arm (2) and protrusion means (1) recover the home position.
