Description

Three-axle hybrid

technical field

The utility model relates to a three-axis hybrid vehicle, in particular to a three-axis hybrid vehicle using a fuel engine and an electric motor.

Background technique

The current hybrid is usually used in two-axle vehicles, where the fuel engine and electric motor drive the front or rear axle of the vehicle in series or parallel. Generally speaking, when the hybrid vehicle is running at low speed, the electric motor is used as power; when driving at high speed, the fuel engine and the electric motor work at the same time; when braking, the fuel engine is turned off, and the electric motor reverses to charge the battery.

A three-axle car with a front axle, a middle axle and a rear axle is generally a relatively large commercial vehicle, such as a bus, passenger car, truck, etc. In such a large vehicle, if only a single power drive from a fuel engine or an electric motor is used , the performance of starting or climbing under the condition of full load is poor. on the pass.

Contents of the invention

The purpose of the utility model is to provide a three-axle hybrid electric vehicle, which can improve the full-load starting and climbing performance of the vehicle.

The three-axle hybrid vehicle of the present invention includes an axle that can be used for steering, an axle that can be driven by a fuel engine, and an axle that can be driven by an electric motor, and also includes a controller, which has an induction unit for detecting the running state of the vehicle, and controls the The controller can output a control signal to the electric motor according to the running state of the vehicle determined by the sensing signal of the sensing unit.

In an exemplary embodiment of a three-axle hybrid electric vehicle, when the controller determines that the vehicle is in a full-load starting state or a hill climbing state, the controller outputs a control signal for operating the electric motor.

In another exemplary embodiment of the three-axle hybrid vehicle, the electric motor is a wheel housing electric motor.

Since one of the axles in these three-axle hybrid vehicles can be driven by the motor, the performance of the vehicle under heavy load conditions can be improved, especially when the vehicle starts and climbs with a full load, the motor can provide auxiliary power for the vehicle, improving The full-load starting and climbing performance of the three-axle vehicle is improved.

In addition, in the three-axis hybrid vehicle, the wheel shell motor is selected as the auxiliary power of the vehicle, and it can be converted into a three-axis hybrid vehicle without making major changes to the structure of the pure fuel-powered three-axis vehicle. The structure is simple and the modification is convenient.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation of the utility model is now described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an exemplary embodiment of a three-axle hybrid vehicle, as shown in the figure, a vehicle 100 has three axles 12, 14 and 16, which are respectively the front axle, middle axle and rear axle of the vehicle , where the axle 12 placed at the front of the vehicle is a steering shaft, and the axles 14 and 16 placed at the middle and rear of the vehicle can be connected to the fuel engine and the electric motor respectively. In the embodiment shown in Figure 1, the axles placed at the rear of the vehicle 16 is connected with the fuel engine 60, when the vehicle 100 runs normally, the fuel engine 60 can drive the axle 16, and then drive the wheels to rotate. Of course, those skilled in the art can understand that in other implementations, the fuel engine 60 can also drive the axle 14 located in the middle of the vehicle 100 .

In the embodiment shown in FIG. 1 , motors 40 are provided on the wheels 42 at both ends of the axle 14 placed in the middle of the vehicle. Although in the illustrated embodiment, the shown motor 40 is a wheel shell motor, those skilled in the art can understand that in other embodiments, other forms can also be selected to connect the motor to the axle, such as using a single motor drive, The torque of the electric motor is transmitted to the two electric drive wheels through the differential. Of course, the wheel shell motor can be converted into a three-axle hybrid vehicle without a lot of changes to the structure of the pure fuel-powered three-axle vehicle, and the structure is simple and easy to refit.

The vehicle 100 also includes a controller 50, the controller 50 has a sensing unit 52 capable of detecting the working conditions of the vehicle. Those skilled in the art can understand that the sensing unit 52 generally includes various sensors arranged on the vehicle 100, such as being arranged on Temperature, pressure, throttle opening and other sensors on the fuel engine 40, as well as sensors arranged in other parts of the vehicle. The controller 50 can determine the running state of the vehicle according to the sensing signals of these sensors, and output control signals to the electric motor 40 accordingly. For example, the controller 50 can output control signals to the electric motor 40 when the vehicle starts, accelerates, climbs a slope, and runs at a high speed, so as to improve the dynamic performance of the vehicle in these situations.

In the embodiment shown in FIG. 1 , when the controller 50 determines that the vehicle is starting with a full load or climbing a slope according to the sensing signal of the sensing unit 52, the controller 50 outputs a control signal to the electric motor 40, allowing the electric motor 40 to be driven as an auxiliary power. The axle 14 makes the wheel 42 change from a driven wheel in a normal state to a driving wheel, so as to improve the starting and climbing performance of the vehicle 100 .

Since the electric motor plays the role of auxiliary power when the vehicle is starting with full load or climbing a slope, this hybrid power is suitable for three-axle extended vehicles, double-decker vehicles or articulated vehicles, etc.

A series of detailed descriptions listed above are only specific descriptions for the feasible embodiments of the present utility model, and they are not intended to limit the scope of protection of the present utility model. Embodiments or changes should be included within the protection scope of the present utility model.
