Problems solved by technology

[0004] The present invention provides a powertrain system of an extended-range electric vehicle, which can effectively solve the problem in the above-mentioned background technology that currently chooses to use a hybrid vehicle assembly with a CVT continuously variable automatic transmission. The output of power is linear, and the driving is too stable. It lacks the stable acceleration performance of traditional manual transmissions, and there is no push-back feeling, which reduces the driving pleasure

Embodiment 1

[0041] Embodiment 1: as Figure 1-4 As shown, the present invention provides a technical solution, a powertrain system of an extended-range electric vehicle, including a mounting beam 1, the mounting beam 1 forms a high-low structure by a supporting beam 2, and the inclination angle of the supporting beam 2 is 45 degrees, and one end of the mounting beam 1 Both sides and the middle of the other end are embedded with fixing bolts 3, so as to facilitate the installation of the automobile assembly. The inner side of the mounting beam 1 is welded with a load-bearing plate 4, and the top of the load-bearing plate 4 is embedded with a sound-absorbing plate 5, and the top of the sound-absorbing plate 5 is installed with a motor 6 , one end of the motor 6 is connected to the gearbox 7, and one end of the gearbox 7 is embedded with a gearbox shaft 8;

[0042] The center of one end of the motor 6 is connected with a temperature sensor 9, the bottom of the temperature sensor 9 is equippe...

Embodiment 2

[0046] Embodiment 2: as Figure 5 As shown, the present invention provides a technical solution, a powertrain system of an extended-range electric vehicle, the PID module converts the gradient received by the MCU controller from the accelerator pedal into the output of the battery, and the battery starts the motor 6 and drives the motor 6 to perform Rotate, and the temperature sensor 9 measures the temperature of the motor 6, and transmits it to the MCU processor through the microprocessor 16, and the MCU processor controls the oil output of the gearbox 7 output pump, thereby controlling the speed.

[0047] The calculation method in the PID module is as follows:

[0048] Y=K p e(t);

[0049] Among them, y is the regulator output;

[0050] Kp is the proportional coefficient;

[0051] e(t) is the regulator input deviation;

[0052] And the integral adjusts it as follows:

[0053]

[0054] In the formula:

[0055] T1 is the integral time constant, which represents the mag...

Abstract

The invention discloses a power assembly system of an extended-range electric vehicle. The system comprises a mounting beam, and a bearing plate is welded at one end of the inner side of the mountingbeam; a sound absorption plate is embedded into the top end of the bearing plate; a motor is mounted at the top end of the sound absorption plate; one end of the motor is connected with a gearbox; andone end of the gearbox is connected with a gearbox shaft in an embedded mode. The power assembly system is scientific and reasonable in structure and safe and convenient to use, the motor and the gearbox are placed on the mounting beam for normal installation, a first supporting rod and a second supporting rod are used for supporting, and the temperature and noise vibration of the motor and the gearbox are measured, so that normal detection and support of the motor and the gearbox are ensured, an MCU controller is adjusted through a PID module, after a driver steps on an accelerator pedal, the rotating speed of the motor is adjusted through the MCU controller, acceleration and deceleration can be rapidly achieved, the PID module conducts proportional adjustment on the stability of the motor and the output quantity of the storage battery, and therefore the rotating speed of the gearbox is controlled.

Description

technical field [0001] The invention relates to the technical field of power for an extended-range electric vehicle, in particular to a power assembly system for an extended-range electric vehicle. Background technique [0002] Powertrain, the English name Powertrain or Powerplant, refers to a series of components and components that generate power on the vehicle and transmit power to the road surface. In a broad sense, it includes engines, gearboxes, drive shafts, differentials, clutches, etc. But under normal circumstances, the powertrain generally only refers to the engine, gearbox, and the rest of the parts integrated into the gearbox, such as clutch / front differential, etc.; [0003] At present, the hybrid electric vehicle assembly that uses the CVT continuously variable automatic transmission is selected. The power output is linear, and the driving is too smooth, which lacks the stable acceleration performance of the traditional manual transmission and does not have th...
