Description

Drive axle end parallel hybrid drive assembly

technical field

The utility model relates to a power drive assembly, in particular to a drive bridge end parallel hybrid drive assembly.

Background technique

Hybrid means that the car uses internal combustion engine drive and electric motor drive. The advantage is that the internal combustion engine and electric motor can be used alone or in combination according to different situations. During braking and deceleration, the electric motor can be converted into a generator to recover energy. When the vehicle stops Stop the engine, therefore, the hybrid drive can use a small-displacement internal combustion engine to achieve energy-saving and environmental protection effects, improve acceleration performance, still use a single petroleum fuel, and maintain the convenience of traditional cars. Existing hybrid vehicles have complex structures and high costs.

Contents of the invention

The purpose of the utility model is to provide a hybrid drive assembly with simple structure and wide adaptability.

The purpose of this utility model is achieved through the following approaches.

A drive axle end parallel hybrid power drive assembly, which includes a drive axle final reducer and a motor/generator. The control unit controls the motor operation mode and generator operation mode selected for operation. The rotor in the motor/generator is connected to the input shaft of the drive axle final reducer, and the motor/generator is connected to the vehicle's electronic control unit and battery.

Connecting the rotor of the motor/generator in the hybrid power drive assembly to the input shaft directly realizes the power hybrid mode of mechanical parallel connection, and the structure is simple and reliable.

The connection mode of the rotor in the described motor/generator and the input shaft of the drive axle final reducer is:

Adopt spline connection, or other movable connection methods that are detachable.

The drive axle input shaft and the motor/generator are connected in parallel.

The motor/generator is a thin motor/generator.

The rotor of the thin motor/generator is fixed on the housing of the motor/generator with bearings, so that the stator and the rotor maintain an appropriate magnetic gap. The rotor is a through-type hollow structure with splines inside, and one end of the input shaft of the drive axle It is a driving bevel gear, and the other end is provided with an external spline, and the external spline on the input shaft of the drive axle cooperates with the internal spline of the rotor.

When installing, pass the external spline on the other end of the drive axle input shaft through the internal spline hole of the rotor to realize mechanical parallel connection with the power of the motor/generator.

The utility model has the advantages of realizing the parallel mixing of two kinds of power at the end of the driving axle, where the mixing is realized, the layout space is relatively abundant, the structure is simple, and it is suitable for a large number of pickup trucks with an integral driving axle structure. It is used in the hybrid design of medium-sized passenger cars and trucks.

Detailed ways

Below in conjunction with embodiment the utility model is described in more detail.

Example:

A drive axle end parallel hybrid drive assembly as shown in FIG. 1 , which includes a drive axle final reducer and a motor/generator. The motor/generator is an integrated structure. The integrated motor/generator has a motor operation mode and a generator operation mode controlled by an electronic control unit. The rotor 3 in the motor/generator is connected to the input shaft of the drive axle main reducer. 4, the motor/generator is connected to the vehicle's electronic control unit and battery. The motor/generator is a thin motor/generator, and the rotor is fixed on the housing 1 of the motor/generator with bearings, so that the stator 2 and the rotor maintain an appropriate magnetic gap. The rotor is a through-type hollow structure with splines inside. , one end of the input shaft of the drive axle is a driving bevel gear, and the other end is provided with an external spline.

The utility model replaces the original driving axle and is installed on the automobile. Except that the length of the transmission shaft is shortened, the connection of the mechanical parts is the same as that of the original automobile. When the car needs to accelerate or climb a slope, the motor/generator is controlled to be in the motor state, and the torque generated by the motor rotor and the torque generated by the car drive shaft are mixed and transmitted to the input shaft of the bevel gear through the spline parallel connection. Simply accept the transmission shaft torque to obtain greater power; when the car starts to brake, the motor/generator is controlled to be in the generator state, and the rotational kinetic energy of the transmission shaft is consumed to generate electricity and stored in the battery to produce a braking effect (shaft Braking); in general flat road driving, the motor/generator is in a free state, and the state of the vehicle is the same as that of a traditional internal combustion engine vehicle.

The parts not described in this embodiment are the same as the prior art.
