Embodiment Construction

[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the present embodiment provides a vehicle, which includes a power source E and a continuously variable transmission system T. The power output by the power source E is output after being shifted by the continuously variable transmission system T. Wherein, the continuously variable transmission system T includes a parallel shaft gear transmission mechanism, a first clutch 1 , a second clutch 2 and a metal belt type continuously variable transmission 6 . in:

[0024] The parallel shaft gear transmission mechanism includes a reverse gear set 5 and a first input shaft 30 , a second input shaft 31 , and an output shaft 33 arranged in parallel. The reverse gear set 5 includes a reverse driving gear 50, a reve...

Abstract

A vehicle and a continuously variable transmission system, the transmission system includes a parallel shaft gear transmission mechanism, including a reverse gear set and first and second input shafts and output shafts arranged in parallel, and the reverse drive gear is fixedly sleeved on the second input shaft On the top, the reverse driven gear is fixedly sleeved on the output shaft; one end of the first clutch is connected to one end of the first input shaft; one end of the second clutch is connected to one end of the second input shaft; the metal belt continuously variable transmission, its The main working wheel is anti-torsionally connected with the other end of the first input shaft, and the central axis of the main working wheel is parallel to the first input shaft, and the slave working wheel is connected with the output shaft, and drives the output shaft to rotate when the slave working wheel rotates. The present invention cancels the hydraulic torque converter, planetary gear set and synchronizer, which not only simplifies the structure, but also avoids the large size, heavy weight and low transmission efficiency of the hydraulic torque converter, the complex structure of the planetary gear set, and the difficulty in manufacturing Big question.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a vehicle and a continuously variable transmission system. Background technique [0002] Continuously variable transmission system can realize stepless transmission, so that the vehicle shifts smoothly, without the frustration of traditional continuously variable transmission system when shifting gears, so it is more and more valued by vehicle manufacturers. At present, most continuously variable transmission systems include a hydraulic torque converter and a planetary gear set. The power of the power source (such as an engine) is transmitted to the planetary gear set through the hydraulic torque converter. Different speed and torque can be output. [0003] However, the existing continuously variable transmission system has the following disadvantages: the hydraulic torque converter is large in size, heavy in weight and low in transmission efficiency; the structure of the plan...
