Problems solved by technology

The disadvantage is that the integration is low; the generator and the drive motor lack an effective deceleration device, and a low-speed high-torque motor is used, which is costly; some synthetic boxes on the market have wet clutches and hydraulic valve plates, and the research and development costs are higher

Embodiment Construction

[0036] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0037] like Figure 1 to Figure 4 The transmission structure for the range-extended hybrid system of the present invention that is coaxially arranged mainly includes a coaxially arranged front box assembly 1, a main box assembly 2 and a rear box assembly 3 (the coaxial arrangement can save the vehicle vertical direction space), the front box assembly 1 includes a generator assembly and two pairs of gear pairs for reducing torque and increasing speed, which are coupled with the engine, and the main box assembly 2 includes a drive motor assembly, which passes through the rear box assembly 3 The two pairs of torque-increasing and reducing gear pairs in the middle transmit the power to the output shaft.

[0038] like figure 2 As shown, the front box assembly 1 mainly includes a front box 4, a generator stator 5, a generator rotor 6, a front cove...

Abstract

The present invention relates to a coaxially arranged transmission structure for an extended-range hybrid system, which includes: a front box assembly, a main box assembly and a rear box assembly coaxially arranged with the front box assembly; The front box assembly includes front box, generator stator, generator rotor, front cover plate, front support plate, input gear shaft, first bearing, second bearing, third bearing, fourth bearing, input secondary drive Gear, input intermediate shaft, fifth bearing, input secondary driven gear, sixth bearing, bearing pressure plate and wave spring; the coaxially arranged transmission structure for the extended-range hybrid system of the present invention has high integration and is easy to match and install Combined box; using a parallel shaft two-stage reduction mechanism, the structure is simple, reliable, and low processing cost; the engine is coupled with the generator to realize the function of extending the power generation; High fuel economy, lower vehicle cost.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicle transmission, and in particular relates to a coaxially arranged transmission structure for a range-extended hybrid system. Background technique [0002] In recent years, with the guidance of national policies and the requirements of vehicle emission regulations, especially under the environment of National VI emission requirements and credit policy environment, various OEMs are vigorously promoting a variety of pure electric vehicles. Plug-in pure electric vehicles have a series of problems such as short cruising range and high battery cost. Therefore, range-extended hybrid vehicles were born under such a background. The range extender is used to generate electricity, which solves the mileage anxiety problem of electric vehicles. [0003] Extended-range hybrid vehicles use electric energy as the direct power source of the vehicle. After the battery power is lower than the SOC (battery rema...
