Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0017] Such as figure 1 , figure 2 The shown automotive continuously variable transmission shifting device includes a shifting cable 14 and a gear shifter for parking gear P, reverse gear R, neutral gear N and forward gear D, which are installed under the bottom of the transmission housing. The rocker arm 15 is equipped with a fixed bracket composed of the bracket main part 1 and the bending part connected with the bracket main part 1 on the transmission housing. The fixed bracket of this embodiment passes through two holes 1-1 in the bracket main part 1. The upper bolts are fixed on the transmission housing; the bending part of the fixed bracket is provided with a card slot 1-2 for clamping the shift cable 14, and a square hole 1-3 is provided near the bottom of the card slot 1-2 ; The shift cable 14 is clamped in the card slot 1-2, and the outer hoop of the s...

Abstract

The invention discloses a shifting and switching device of an automobile CVT (Continuous Variable Transmission), which relates to the technical field of automobile manufacturing. The shifting and switching device comprises a shifting inhaul cable and a shifting rocking arm, wherein the shifting rocking arm is arranged under the bottom of a transmission housing and is provided with a parking gear, a reverse gear, a neutral gear and a forward gear, the transmission housing is provided with a fixing support which is formed by a support part and a bending part which is connected with the support part, the bending part is provided with a clamping groove which is used for clamping the shifting inhaul cable, the support part is hinged to an intermediate transition board through a rotating shaft, the intermediate transition board is hinged to the shifting inhaul cable through a first pin shaft, and the intermediate transition board is connected with a transition rod through a second pin shaft. Compared with the prior art, according to the shifting and switching device disclosed by the invention, the problems that the turning radius of the shifting inhaul cable is too small as the shifting inhaul cable of a certain automobile is connected with the shifting rocking arm, thus the shifting force is large, the shifting comfort is poor, and the layout of the automobile CVT is difficult can be avoided, and the shifting performance is greatly increased.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a shift conversion device used between a shift cable and a shift rocker arm of a continuously variable transmission of an automobile. Background technique [0002] Automobile continuously variable transmission is a relatively advanced automatic transmission, which has outstanding performance in terms of comfortable shifting and fuel economy of the whole vehicle. Because there is no power interruption for gear shifting, the car equipped with the CVT has a good comfort experience such as no shock when shifting gears; the CVT realizes the speed ratio change by changing the radius of the two sets of cone wheels, and can be used in the range of speed ratios. Continuously output unlimited sets of speed ratios, so that the engine can continue to work in the low fuel consumption area, so as to achieve the purpose of reducing fuel consumption. The gear position of the co...
