Gear shifting servo system

Abstract

The invention relates to a gear shifting servo system. The system comprises a gear shifting input shaft, a transmission mechanism, a deflection mechanism, a servo valve structure, a gear shifting executing mechanism and a positioning mechanism, wherein the gear shifting input shaft drives a driven element to rotate synchronously; when the driven element rotates, a deflection element connected withthe driven element through a pin roll can be synchronously driven; and an output shaft is in a fixed state at a gear box end at the beginning of starting, the deflection element swings leftwards or rightwards by taking the output shaft as a rotating center, a deflection executing element transversely moves under the deflection of the deflection element, and an air valve in a servo valve structureis opened, so that the assisting effect is achieved. Through the conversion of the deflection mechanism, linear motion is transferred to an inhaul cable or a rod through the transmission mechanism bya shift rod of a shifter, then rotary motion generated by the linear motion on the gear shifting input shaft can be converted into the linear motion of the gear shifting output shaft which is almostin the same longitudinal position as the transmission mechanism. With the system, gear shifting force can be remarkably reduced, the gear shifting comfort is improved, the occupied space is small, theinstallation is convenient, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of automobiles and relates to a gear shift servo system. Background technique [0002] The commonly used shift assist system in the market is as follows: figure 1 As shown, when the input end is pushed and pulled through the shift lever or the flexible shaft, the air valve inside the booster will be opened at the same time, and the piston inside the booster will be driven by the input of external air source to achieve the boosting effect, which is characterized by linear motion. In the existing technology, the linear motion output to the gearbox is staggered and superimposed in one direction with the shift input shaft. This system has a large structure and shape, which is not conducive to occasions with limited space requirements. Moreover, due to the large overall frame, the weight is also low. Large size is not conducive to light weight, which means that existing products have disadvantages such as large size, labo...

In the existing technology, the linear motion output to the gearbox is staggered and superimposed in one direction with the shift input shaft. This system has a large structure and shape, which is not conducive to occasions with limited space requirements. Moreover, due to the large overall frame, the weight is also low. Large, not conducive to lightweight, that is to say, existing products have disadvantages such as large size, laborious shifting, inconvenient installation, and high cost
