The switch has the advantages that service life of the switch is more than 2 million times; cost of the switch is 50% lower than that of an electronic neutral gear switch.
Description
Technical field
The utility model relates to a kind of auto-manual speed change automobile dry-reed neutral position switch, is hand, automatic speed changing automobile gearbox neutral position switch more specifically.
Background technique
At present, on market, have two kinds of neutral position switch, one is mechanical type neutral position switch, and one is electronic type neutral position switch.
The mode of operation of mechanical type neutral position switch: in the time of shift of transmission, shifting block rotates, and shifting block is stirred push rod and moved up and down, when neutral, push rod moves down, contact contact, circuit is connected, and switch signals to ECU control module, and then changes the control strategy of motor and speed changer.
The mode of operation of electronic type neutral position switch: in the time of shift of transmission, set rotation ahead, the angle difference of setting ahead, magnetic density difference, the signal difference that the sensor of switch receives, and then whether definite speed changer is at neutral gear position.Switch signals to ECU control module, changes the control strategy of motor and speed changer.
The frequency of utilization of neutral position switch is higher, thereby determines that its life-span will reach more than 1,000,000 times.The working life of mechanical type neutral position switch is lower, can not meet customer requirement, although and the life-span of electronic type neutral position switch can meet customer requirement, price too high (being 4 times ~ 5 times of price of mechanical type neutral position switch).
Summary of the invention
The purpose of this utility model be for overcome existing product defect, improve product working life, reduce the price of product, and a auto-manual speed change automobile dry-reed neutral position switch of research and development.
The technological scheme that the technical problem that the utility model solves adopts is auto-manual speed change automobile dry-reed neutral position switch, comprise plug assembly, spring, pressing plate, seal ring, back-up ring, sealing gasket, housing, push rod assembly and steel ball, wherein plug assembly comprises plug, inserted sheet I and inserted sheet II, inserted sheet I, inserted sheet II is together with plug injection moulding, the bottom of the cylindric hollow cavity of ladder-type of described housing is upwards equipped with steel ball successively, push rod assembly, spring, plug assembly, the top of housing and the sidewall of plug assembly are riveted together, steel ball card is in the reducing platform of housing bottom, described push rod assembly comprises packing ring, magnet circle and push rod, have a dry reed-pipe to be placed within the scope of the magnetic field induction of magnet circle, under the inserted sheet in upper and lower pin and the plug assembly of dry reed-pipe, extended end links together.
Described inserted sheet adopts contactless laser bonding to be connected with the Placement of dry reed-pipe pin.
Described seal ring is fluorine rubber ring.The welding of inserted sheet and dry reed-pipe adopts contactless laser bonding, adopts special tooling to ensure fixing and the dimensional stability of welding.
Described seal ring is that fluorine rubber is made, and this material is high temperature resistant, corrosion-resistant, oil resistance is good, meets Environmental Conditions requirement.Sealing gasket is that aluminium is made after screw threads for fastening, plays seal action.
Push rod assembly packs housing into, and the part that steel ball exposes housing contacts with setting ahead of gearbox, has improved the wear-resisting property of product.
The beneficial effects of the utility model are:
1, the life-span of the utility model product reaches more than 2,000,000 times;
2, the cost of the utility model product is lower by 50% than the cost of electronic type neutral position switch;
3, the utility model product is simple in structure, reliable performance.
