AI Technical Summary

Problems solved by technology

Otherwise, it may not be possible to shift gears smoothly and lead to gear hitting
[0003] The problem existing in the prior art is that the driver can only obtain the current driving gear of the car by feeling and experience, without any objective and real car gear signal for reference, and cannot accurately guarantee the correct clutch when the car shifts gears

Embodiment 1

[0025] Example 1, such as figure 1 As shown: a gear sensing system, which includes a gear sensing mechanism 1, a magnetic column 2, and a sensing mechanism mounting plate 3, wherein the gear sensing mechanism 1 is mainly composed of a Hall element 4 and a housing 5, Seven Hall elements 4 are arranged on the bottom of the housing 5; the gear sensing mechanism 1 is fixed on the bottom surface of the sensing mechanism mounting plate 3, and a magnetic column is arranged below the gear sensing mechanism 1 2. When the magnetic head on the top of the magnetic column 2 is aligned with any Hall element 4 in the gear sensor mechanism 1, the Hall element 4 receives a signal to work.

[0026] Each Hall element 4 is connected to a signal resistor R1 and forms a signal circuit; wherein the first Hall element 4 is connected to the first signal resistor R1, the nth Hall element 4 is connected to the nth signal resistor Rn, and each signal circuit The high-level output terminals of the Hall e...

Embodiment 2

[0035] This embodiment 2 is consistent with the structural principle of embodiment 1, and its difference is:

[0036] Each Hall element 4 is connected with a signal resistor R1, and forms a signal circuit; the low-level output terminals of each signal circuit are connected together to form a common signal output terminal OUT, and the signal output terminal OUT is connected in series with a resistor R connected to the ground; the power terminals of the Hall elements 4 are connected in parallel to the vehicle power supply; the high level terminals of each Hall element 4 are connected to the high level provided by the vehicle battery.

[0037] It works as follows:

[0038] The gear position sensing mechanism 1 is fixed on the automobile gearbox casing 12a, the magnetic column 2 is fixed on the shift rod 12b of the gearbox, and is connected with the control handle of the driver's cab through the shift rod 12b, and the driver controls the operation When the handle is used to drive...

Abstract

The invention discloses a gear sensing mechanism, which is characterized in that the gear sensing mechanism comprises a gear sensing device (1), a magnetic column (2) and a gear sensing device installing plate (3), wherein, the gear sensing device (1) is mainly composed of hall elements (4) and a casing body (5), wherein, 4 to 7 hall elements are arranged at the bottom part of the casing body (5); the gear sensing device (1) is fixed on the bottom surface of the gear sensing device installing plate (3), the magnetic column (2) is arranged below the gear sensing device (1), and the hall elements (4) receive signals to operate when a magnetic head at the top part of the magnetic column (2) is aligned to an arbitrary hall element (4); each hall element is connected with a signal resistance to form a signal circuit; output terminals of the signal circuits are connected together to form a shared signal outputting terminal OUT. The gear sensing mechanism has the technical advantage that objective and actual vehicle gear signals can be provided according to different gear conditions to ensure the right on-off during the gear changing of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile gear shifting devices, and in particular relates to an automobile gear position sensing system. Background technique [0002] Usually, the manual shift transmission used in automobiles requires the driver to operate the clutch pedal with his left foot, the accelerator pedal or brake pedal with his right foot, and the gear lever with his right hand to change gears. It takes a long time to practice the coordination and cooperation of the three actions proficiently. The most technically difficult thing is to manipulate the clutch pedal, which is very labor-intensive when changing gears frequently. Now some cars use automatic transmissions; this gear mechanism completely frees the driver from using the left foot to control the clutch and the right hand to control the gear lever. But using an automatic transmission greatly increases the cost of the car and also makes the driver lose the joy of manu...
