Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] Such as figure 1 Shown:

[0047] Driving mode driven by the engine alone:

[0048] When the engine drives the vehicle alone, the motor does not output power. At this time, the power transmission route of the engine is as follows:

[0049] Engine 11 → external gear two 10 → external gear one 9 → internal gear 8 → planetary gear 6 → output gear 7 → output shaft 12;

[0050] At this time, the transmission is equivalent to a simple planetary gear reducer, and the speed of each component is calculated as follows:

[0051]

[0052] no 8 =n 9

[0053]

[0054] no 11 =n 10

[0055] Combine the above formulas to get:

[0056]

[0057] The meanings of the parameters in the above formulas are as follows:

[0058] i—transmission ratio; n—gear speed (rev / min); Z—number of gear teeth

[0059] Engine alone drive parking mode:

[0060] In this m...

Abstract

The invention discloses a hybrid vehicle transmission and an operation method thereof. The hybrid vehicle transmission comprises a motor and an engine, the output end of the motor is connected with the input end of a driving input belt wheel, the output end of the driving input belt wheel is connected with the input end of a driven output belt wheel through a steel belt, the output end of the driven output belt wheel is connected with the input end of a planet gear through a planet carrier, and the planet gear is externally engaged with an output gear and internally engaged with an inner gear;the output end of the engine is connected with a second outer gear, the second outer gear is externally engaged with a first outer gear, the first outer gear and the inner gear are of an integrated structure, the first outer gear and the inner gear are consistent in rotating speed, and the first outer gear is connected with the output gear through the inner gear; and an output shaft is arranged on the output gear, penetrates through gear shaft holes of the first outer gear and the inner gear, and is not in contact with the first outer gear and the inner gear. The CVT speed change and the planet gear speed change are combined to achieve large-torque stepless speed change transmission.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a hybrid vehicle transmission and an operating method thereof. Background technique [0002] With the increasing energy crisis and the increasingly stringent national emission standards, the market share of hybrid vehicles and electric vehicles will increase. The existing automotive transmissions are mainly caused by the following problems: [0003] It is impossible to achieve high-torque stepless transmission; it is impossible to make the motor and engine work in the optimal range. Contents of the invention [0004] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a hybrid vehicle transmission and its operating method. This transmission has three major driving modes, which are respectively driven by the engine alone, driven by the motor alone, and jointly driven by the engine and the motor. Through...
