Problems solved by technology

[0003] Among them, AMT is widely used in cars, but currently it is not used in heavy trucks.
[0004] The AMT switches on the existing heavy trucks are all controlled by contacts. Among them, the contact control is prone to contact wear, the contacts are covered with dust, resulting in poor contact, and the leakage of the AMT switch leads to short circuit of the contacts.

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Such as Figure 1-Figure 5As shown, the present invention discloses an AMT switch for 24V heavy trucks, which includes a switch housing 1, a knob 2, a rotating shaft 21 and an integrated circuit board 3, and the knob 2 and the rotating shaft 21 are in the shape of a circular column whose axial direction is vertical , and the knob 2 is fixed on the outer periphery of the rotating shaft 21 by clamping, and the rotating shaft 21 is arranged above the switch housing 1 by rotating in a circle. In addition, a magnet gear ring 22 is installed below the rotating shaft 21 by clamping, and the magnet The gear ring 22 is embedded with a magnet 221 that rotates with the knob 2. In addition, the integrated circuit board 3 is fixedly installed on the switch housing 1 by ...

Abstract

The invention relates to an AMT switch for a 24V heavy truck. The switch comprises a switch shell, a knob and an integrated circuit board. The knob is rotatably arranged on the switch shell, a magnetrotating along with the knob is fixedly arranged on the knob, the integrated circuit board is fixedly arranged on the switch shell, and a plurality of Hall sensors are arranged on the integrated circuit board along the rotating track of the magnet. By adopting the scheme, the AMT switch for the 24V heavy truck generates different electric signals on the integrated circuit board through induction of different Hall sensors and magnets, and realizes accurate induction and no contact.

Description

technical field [0001] The invention relates to the field of vehicle shift switches, in particular to an AMT switch for 24V heavy trucks. Background technique [0002] AMT is an electronically controlled mechanical automatic transmission. It is composed of a dry clutch and a manual gear transmission plus an electronic control system. It combines the convenience of AT and the efficiency of MT. [0003] Among them, AMT is widely used in cars, but currently it is relatively scarce in heavy trucks. [0004] The AMT switches on the existing heavy trucks are all controlled by contacts. Among them, the contact control is prone to wear and tear of the contacts, the contacts are covered with dust and cause poor contact, and the AMT switch leaks and the contacts are short-circuited. Contents of the invention [0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a kind of electric signal used in 24V heavy trucks that generates diffe...
