Gear sensor and vehicles with it

Abstract

The invention discloses a gear sensor and a vehicle provided with the same. The gear sensor comprises a public guiding rail, a plurality of gear signal guiding rails, a contact pin provided with a public signal terminal and multiple gear signal terminals, and a slide block. The gear signal guiding rails are provided with guiding sections and insulating sections, the public signal terminal is connected with the public guiding rail, the multiple gear signal terminals are respectively and correspondingly connected with the plurality of gear signal guiding rails, and the slide block is respectively contacted with the public guiding rail and the multiple gear signal guiding rails and can slide between the guiding sections and the insulating sections so as to enable corresponding gear signal terminals to have different potential. The gear sensor has the advantages that deviation between an input signal and an actual mechanical displacement signal is small, the accuracy of an output signal is high, a gear signal is accurate, and the like.

Description

technical field [0001] The invention relates to vehicle engineering, in particular to a gear sensor and a vehicle with the gear sensor. Background technique [0002] With the popularity of cars equipped with automatic transmissions in domestic and foreign markets, the range of applications of transmission gear sensors is becoming more and more extensive. The principle of the existing contact gear sensor 10' is that a gear guide rail and a rotor are arranged inside the gear sensor 10', and the rotor is in contact with the guide rail through elastic contacts and can rotate around its center. The gear sensor 10' is assembled on the long shift shaft 20', and the long shift shaft 20' is moved by the pawl 30', thereby driving the rotor of the gear sensor 10' to rotate at a certain angle, and the signal pins of each gear are formed The level combination code represents the position of each gear and the gear change signal. [0003] But the mechanical transmission process of the ex...

Problems solved by technology

[0003] But the mechanical transmission process of the existing gear sensor 10' is: long axis of shifting 20'-pawl 30'-manual valve drive rod 40'-manual valve 50' (such as figure 1 As shown), there are many mechanical transmission parts and the transmission method is complex, not only there is a large cumulative manufacturing error, but also the cumulative assembly error will be generated during the assembly process, which leads to the difference between the input signal of the gear sensor 10' and the actual mechanical displacement signal The deviation is large and the accuracy of the output signal is low, which will cause problems such as inaccurate or wrong signal output of the gear position
