Description
Technical field
The utility model belongs to vehicle chassis technology field, and in particular to a kind of clutch switch.
Background technique
Clutch switch is typically mounted on clutch pedal and is taken in pedal when moving up and down to extreme position, and clutch switch is logical
The conducting and disconnection for crossing internal circuit, to ECU (electronic control unit) input high-low voltage signal, thus control vehicle launch or
Engine torque output.The on-off of clutch switch is ensured by the control that is contacting and separating between movable contact spring and static contact at present
The good contact of movable contact spring and static contact is always the design focal point of clutch switch.
Two piece of first static contact and two piece of second static contact are generally installed in the shell of existing clutch switch, in push rod
On be provided with the first movable contact spring and the second movable contact spring, and the first movable contact spring is set to the top of the second movable contact spring, and two piece first is quiet
The second switch that the first switch circuit that contact and the first movable contact spring are constituted, two piece of second static contact and the second movable contact spring are constituted returns
Road.When not stepping on pedal, the second movable contact spring and two piece of second static contact separation disconnect second switch circuit, and the first movable contact spring connects
First switch circuit is connected in logical two piece of first static contact, exports low-voltage signal；Stepping on pedal moves down push rod, the first movable contact spring
Separating with two piece of first static contact disconnects first switch circuit, and the second movable contact spring and two piece of second static contact conducting make first to open
Circuit conducting is closed, high-voltage signal is exported.The high-low pressure signal output of clutch switch is controlled by the on-off of two switching circuitries,
Movable contact spring is required to well just be able to achieve conducting with two pieces of static contact contacts in every primary Ioops, is easy to appear one in practical operation
There is the phenomenon that virtual connection on block static contact, clutch switch is caused to break down and fail.
Summary of the invention
The utility model aiming at the above problems existing in the prior art, provides one kind, to be solved in the utility model
Technical problem is: how to ensure the good contact of movable contact spring and static contact in clutch switch.
The purpose of this utility model can be realized by the following technical scheme:
A kind of clutch switch including shell and is inserted in the push rod that can be slided in the shell and along the shell, institute
It states and is installed with the first static contact, the second static contact, the first movable contact spring and the second movable contact spring in shell, the first movable contact spring and first quiet
Contact is connected, and first boss and second boss are installed on the push rod, and the second boss and second movable contact spring contradict
And making the separated of second movable contact spring and the second static contact, the push rod, which slides axially, can make the first boss contradict institute
The first movable contact spring is stated to disconnect first movable contact spring and first static contact and the second boss is made to be detached from described second
Movable contact spring is to be connected second movable contact spring and the second static contact.
First static contact and the first movable contact spring constitute first switch circuit, and the second static contact and the second movable contact spring constitute second
Switching circuitry.When first pedal is not stepped on (push rod is under normal conditions), second boss, which contacts on the second movable contact spring, makes second to move
Contact and the separation of the second static contact, the first movable contact spring are fitted on the first static contact, lead the first movable contact spring and first quiet place's piece
It is logical, realize that the conducting of first switch circuit and second switch circuit disconnect；When stepping on pedal, push rod axial direction slide downward drives the

It is logical, to ensure the good contact of movable contact spring and static contact in clutch switch；Structure design simultaneously is simple, is convenient for space cloth
Office.
In above-mentioned clutch switch, the butting section is the arc-like sheet being inclined outwardly from its lower end towards upper end, described
The outer end of first boss has the arcwall face being oppositely arranged with the butting section.Butting section and first boss are contradicted by cambered surface,
The deformation for being conducive to alleviate butting section and first boss, ensures the elastic recovery of butting section, to ensure contact portion and first quiet
The good contact of contact.
In above-mentioned clutch switch, second movable contact spring is including the second conductive part and is set to second conduction
The abutting part of portion upper end, second static contact are oppositely arranged with one end of the abutting part, and the second boss contacts at institute
The other end for stating abutting part makes the separated of second static contact and the abutting part.It is convenient for passing through one end of abutting part in this way
With second boss against or separation, drive the abutting part other end separate or second static contact of contact, ensure second boss and support
The contact of abutting contact and the second contact portion and the second stationary contact plate rack between socket part is connected, to ensure clutch switch
The good contact of middle movable contact spring and static contact；Structure design simultaneously is simple, is convenient for space layout.
In above-mentioned clutch switch, the abutting part includes riser, and the upper/lower terminal of the riser is towards outer incline
Setting.Setting abuts against convenient for second boss with riser is contacted in this way.
In above-mentioned clutch switch, the second boss is L-shaped.L-shaped second boss reduce second boss and
The conflict area of riser, can be relieved the deformation of second boss and riser, ensure the elastic recovery of riser, thus ensure connect riser and
The good contact of second static contact.
In above-mentioned clutch switch, the first boss and the second boss are respectively arranged at the two of the push rod
Side, and the position of the first boss is higher than second boss.One high and one low two boss being oppositely arranged are conducive to ensure one
The contact of boss and movable contact spring and the separation of another boss and another movable contact spring, to ensure the logical of two circuits
The normal output of disconnected control and clutch engagement signal.
Compared with prior art, the utility model has the advantage that is formed using the first movable contact spring and the first static contact
First switch circuit, the second movable contact spring and the second static contact form second switch circuit, and push rod lower end is arranged in by driving
Two boss realize being turned on or off between the first movable contact spring and the first static contact and the second movable contact spring and the second static contact
Between disconnection or conducting significantly reduce poor contact to control the on-off of two switching circuitries in clutch switch
Probability of happening simplifies the internal circuit configuration of clutch, is conducive to ensure the good of movable contact spring and static contact in clutch switch
Good contact.
