Abstract
The invention provides a vehicle manual gearing neutral switch, the assembly of which comprises a gear shifter of a gear box, a cylinder bracket, a cylinder, a Hall element bracket, a Hall element, a bolt and a fixed block, wherein the cylinder is embedded on the cylinder bracket through interference fit; the cylinder bracket is arranged on the gear shifter of the gear box by the cooperation of the fixed block and the bolt, so that the cylinder does synchronized motion along with the gear shifter; the Hall element is arranged and fixed on the Hall element bracket through an encapsulated shell; the Hall element bracket and the gear shifter are fixed on the gear box through a shared bolt; the Hall element is arranged in parallel with the cylinder and aligned with the neutral position; and the Hall element is connected with a connector through wiring harness. When the Hall element is positioned in the magnetic field formed by the cylinder and is electrified in the direction perpendicular to the magnetic field, Hall potential difference is output in the direction perpendicular to the current and the magnetic filed on the Hall element, and when the current passing the Hall element is constant, then the size of the magnetic field is changed to change the potential difference.
Description
Technical field
The invention belongs to motor vehicle transmissions gear indication technical field, specifically a kind of vehicle manual gearing transmission neutral switch.
Background technique
Along with countries in the world are more and more paid attention to the energy-conserving and environment-protective problem, the new-energy automobile technology that with the mixed power is representative more and more is subjected to extensive concern, and the neutral switch indispensable signal input apparatus of manual gearing transmission (MT) Vehicular hybrid power just, by collection to this signal, can be used as one of decision condition to driver's driving intention: when judging vehicle stop state, neutral switch should be exported the neutral gear signal, and when judging vehicle launch, neutral switch should be exported at the shelves signal.Simultaneously, much more more neutral switch also is applied to by the collection to the neutral gear signal, improve the cornering ability of vehicle in the calibration technique of engine control.Current, the neutral switch technology that existing Motor Vehicle institute extensively adopts mainly is by changing having manual transmission internal structure and gear box casing, by cooperating with leaning of referring to of gear shift, and promote the variation that metal clips is instigated gear in conjunction with elastic mechanism, the major defect of this structure is excessive to the change of gearbox internal structure, and the application on each form manual gearing transmission is used and caused bigger obstacle for neutral switch; In addition, because employing is that the contact-type state is judged structure, the life-span of switch is also shorter, and will bring the problem of inconvenient maintenance thus.
Summary of the invention
Purpose of the present invention is exactly in order to change less the realization and a kind of vehicle manual gearing transmission neutral switch to be provided with lower cost and to former car.
The object of the present invention is achieved like this: it includes a Hall transducer support, Hall transducer, bolt, fixed block, it is characterized in that: shared two construction bolts of Hall transducer support and gearbox gear-shift device together are fixed on the gearbox, on the gearbox gear-shift device, be provided with a U type magnetic column holder by fixed block and bolt, interference fit is inlaid with a magnetic post on U type magnetic column holder, also be provided with a Hall transducer on the parallel position that aligns with this magnetic post neutral position, this Hall transducer is connected by the connector assembly of wire harness with output neutral gear signal and non-neutral gear signal.
When Hall transducer is in the formed magnetic field of magnetic post, and when on direction, passing to electric current perpendicular to magnetic field, to have the output of Hall voltage difference on the Hall transducer with on the electric current direction vertical with magnetic field, when the current constant that passes through Hall transducer is constant, change the size (promptly rotating the magnetic post) in magnetic field, just can change potential difference by the motion of gearbox gear-shift device.Based on this principle, when gear shift, can send electric potential signal with identification neutral gear function.
The present patent application is with respect to the neutral switch structure of other scheme, and this scheme has following characteristics:
Gearbox and operating mechanism thereof there is not any change, be convenient on different gearboxes, carry out fast the application of hardware and software platform, and have the advantage that development cost are low, the construction cycle is short, can avoid other scheme to revise development cost costliness, the long defective of cycle that gearbox caused because of needs.
Reliable in structure.Owing to used the scheme of the Hall transducer that seldom adopts in the construction of switch, the variation of range state is judged by electromagnetic change, owing to can be provided with this variation in sensor, makes signal output become very reliable; Because whole proposal there is no mechanical loss, therefore the degree of accuracy of signal output can not decay; Simultaneously, circuit design is a Lu Changkai, a tunnel normally closed, and also the reliable output for the neutral gear signal provides more multiple guarantee.
Long service life.This structure there is no mechanical loss in neutral gear signal deterministic process, its life-span can have same long lifetime characteristics with Hall transducer.

Embodiment
Embodiment:
By shown in Figure 1, the organization plan of the automobile-used neutral switch of a kind of MT (manual gearing transmission, as follows), its assembly comprises that mainly 4 among Fig. 1 is manual gearing transmission, and 5 is the Hall transducer support, and 6 is Hall transducer, and 9 is bolt; Described Hall transducer support 5 together is fixed on the manual gearing transmission 4 with gearbox gear-shift device 1 shared two construction bolts, on gearbox gear-shift device 1, be set with a U type magnetic column holder 2 by fixed block 10,11 and bolt 9, interference fit is inlaid with a magnetic post 3 on U type magnetic column holder, also be provided with a Hall transducer 6 on the parallel position that aligns with these magnetic post 3 neutral positions, this Hall transducer is connected by the connector assembly 8 of wire harness with output neutral gear signal and non-neutral gear signal.
Its installation steps are: magnetic post 3 is mounted on the magnetic column holder 2 by interference fit, magnetic column holder 2 by with the cooperating of two fixed blocks 10, fixed block 11 and bolt 9, fastening being installed on the gearbox gear-shift device 1, thus realize the purpose that magnetic post 3 is synchronized with the movement with selector reliably; Hall transducer 6 installs and fixes on the Hall transducer support 5 by the housing of encapsulation, and Hall transducer support 5 together is fixed on the gearbox 4 with gearbox gear-shift device 1 shared two construction bolts; Hall transducer 6 and the 3 corresponding parallel installations of magnetic post align at neutral position, and the gap is 1～3mm; Hall transducer 6 links to each other with connector assembly 8 by wire harness 7, output neutral gear signal and non-neutral gear signal.When Hall transducer is in the formed magnetic field of magnetic post, and when on direction, passing to electric current perpendicular to magnetic field, to have the output of Hall voltage difference on the Hall transducer with on the electric current direction vertical with magnetic field, when the current constant that passes through Hall transducer is constant, change the size (promptly rotating the magnetic post) in magnetic field, just can change potential difference by the motion of gearbox gear-shift device.Based on this principle, when gear shift, can send electric potential signal with identification neutral gear function.This scheme have simple installation, to the original structure of gearbox needn't make any change, advantage such as reliable in structure, life-span are long, the batch that helps carrying out hardware and software platform on gearbox is applied.
