Technical Field

The utility model belongs to the technical field of vehicle kinetic energy recovery equipment, and particularly relates to a transmission half shaft power generation mechanism.

Background

The generator is a mechanical device for converting energy of other forms into electric energy, and is usually composed of a stator, a rotor, an end cover, a bearing and other parts. The stator is composed of a stator core, a coil winding, a base and other structural members for fixing the parts. The rotor is composed of rotor iron core (or magnetic pole, yoke) winding, protective ring, central ring, slip ring, fan and rotary shaft. The stator and the rotor of the generator are connected and assembled by the bearing and the end cover, so that the rotor can rotate in the stator and does the motion of cutting magnetic lines of force, thereby generating induced potential, the induced potential is led out through the wiring terminal and is connected in a loop, and then current is generated. The generator has wide application in industrial and agricultural production, national defense, science and technology and daily life. The generator has many forms, but the working principle is based on the law of electromagnetic induction and the law of electromagnetic force. The general principle of its construction is therefore: appropriate magnetic conductive and electric conductive materials are used to form a magnetic circuit and a circuit which mutually perform electromagnetic induction so as to generate electromagnetic power and achieve the purpose of energy conversion.

The existing vehicle generators are all independent modules, are in transmission connection with a power source to generate power, and are processed through an external rectifying circuit, so that the storage battery is continuously and stably charged. However, the generator is directly connected with the engine in a transmission manner, and the original kinetic energy of the wheel cannot be directly transmitted with the existing generator, so that the part of energy cannot be recovered, and a large burden is also caused to a braking system in a continuous braking process.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides a power generation mechanism of a transmission half shaft, which can generate power by adding a set of power generation system on the transmission system of the existing vehicle at the right time, thereby achieving the effect of certain kinetic energy recovery power generation.

The technical scheme adopted by the utility model is as follows:

in a first aspect, the utility model provides a power generation mechanism of a transmission half shaft, which is a device arranged in a vehicle transmission structure for recovering kinetic energy, and comprises a shaft sleeve sleeved outside a driving half shaft, wherein the shaft sleeve is fixed on external structures at two ends of the driving half shaft;

the shaft sleeve is provided with a power generation assembly, the power generation assembly comprises a stator fixed on the shaft sleeve and a rotor arranged on the driving half shaft, the stator is provided with a plurality of coil cores and cables for connecting an external circuit and the coil cores, the rotor is provided with a plurality of excitation windings or permanent magnets, and the driving half shaft drives the rotor to rotate in the stator to generate power in an induction mode.

It should be noted that the main improvement point of the present invention is to provide the conventional power generation mechanism to a specific mechanism of the vehicle, but the present invention is not limited to the use of the vehicle, and the structure of the conventional structure having the drive shaft rotating at a high speed for a long time can be modified by the technical solution of the present invention to achieve the corresponding technical effects.

Meanwhile, the existing power generation mechanism is adopted, and the power generation principle also belongs to the common knowledge of the technicians in the field. The rotor and the stator are designed in a conventional structure, but the structure of the generator with the stator and the rotor is not limited, and the generator comprises a direct current generator and an alternating current generator, and if the generator is the direct current generator, the coil iron core in the stator can be replaced by a permanent magnet.

In the alternating-current generator, the rotor winding does not move to cut the magnetic induction lines, but the rotor generates a rotating magnetic field (the exciting device supplies current to the exciting winding), so that the stator winding moves to cut the magnetic induction lines, induced electromotive force is generated, and the induced electromotive force is led out through the wiring terminal.

The application does not restrict the type and the electricity generation principle of specific electricity generation structure, because most electricity generation mechanism all have rotor and stator structure, other structures are supporting and have ripe solution, set up according to the demand after direct adaptation debugging can. The difference from the prior art is the fixed connection of the stator and the rotor.

The drive axle shaft in the present application is used to connect two external structures, typically a differential and a hub, with the differential being fixed to the frame, while the hub of the vehicle body, which is typically of the load-carrying type, is connected to the frame via a suspension, although with a degree of freedom for multidirectional movement, also with a fixed point. The two ends of the shaft sleeve in the present application are respectively fixed on the two external structures at the two sides of the driving half shaft and keep coaxial with the driving half shaft. The power generation mechanism is fixed through the shaft sleeve, so that on the premise that the structure of the driving half shaft is not changed, the rotor is driven to rotate by the rotation of the driving half shaft through the fixed connection with the driving half shaft, and the power generation effect is achieved.

It should be noted that the driving half shaft can be regarded as always keeping a long-time rotation state, and although the rotation speed continuously changes, because the power generation mechanism is provided with the rectification circuit, the power generation mechanism is similar to the structure in the existing wind power generation mechanism, and the effect of charging the vehicle storage battery can be realized within a certain rotation speed range. And the generator module is not used for replacing the existing power generation mechanism, but is used as a kinetic energy recovery mechanism, so that the electric energy supplement is realized by complementing the existing generator module.

In combination with the first aspect, the present invention provides a first embodiment of the first aspect, wherein the stator has a disc-shaped structure and is fixed on an inner wall of the shaft sleeve by welding or bolting.

With reference to the first aspect, the present invention provides a second implementation manner of the first aspect, wherein the stator has an annular structure and is sleeved outside the shaft sleeve.

With reference to the second implementation manner of the first aspect, the utility model provides a third implementation manner of the first aspect, wherein an annular groove which is recessed inwards is formed in the shaft sleeve, and the stator is clamped in the annular groove.

In combination with the second embodiment of the first aspect, the present invention provides a fourth embodiment of the first aspect, wherein the stator is a detachable structure having at least two sub-portions, and is surrounded on the outer surface of the sleeve by bolts or clips.

In combination with the first aspect, the present invention provides a fifth embodiment of the first aspect, wherein either end of the shaft sleeve has a gap with the connecting end portion of the external structure, the stator has an annular flange inserted into the gap, and the stator is fixedly connected with the shaft sleeve and the external structure through bolts.

In combination with the first aspect, the present invention provides a sixth embodiment of the first aspect, wherein the sleeve comprises at least two segments connected by a flange, and the stator has an annular flange provided at the flange connection and is fixed to the two segments of the sleeve by bolts passing through the annular flange.
