Description:TITLE OF THE INVENTION: A SIDE-MOUNTED IMPULSE GENERATING APPARATUS FOR A LOCOMOTORY DEVICE
FIELD OF THE INVENTION
The present disclosure is generally related to locomotory devices. Particularly, the present disclosure is related to apparatuses, in respect of locomotory devices (apparatuses, for locomotory devices). More particularly, the present disclosure is related to: a side-mounted impulse generating apparatus, in respect of a locomotory device (an impulse generating apparatus, for a locomotory device).
BACKGROUND OF THE INVENTION
Impulse generating apparatuses, in respect of locomotory devices, are known in the art. Such apparatuses are of a complex construction and are disposed at the centre of a rim. Therefore, maintenance becomes challenging, when failures occur. Consequently, in case of rim failures, an entire impulse generating apparatus may have to be replaced.
Further, in such apparatuses, a propelling member is disposed separately, in the locomotory device; this requires a wiring harness.
There is, therefore, a need in the art, for: a side-mounted impulse generating apparatus, in respect of a locomotory device, which overcomes the aforementioned drawbacks and shortcomings.
SUMMARY OF THE INVENTION
A side-mounted impulse generating apparatus, for a locomotory device, is disclosed. Said apparatus broadly comprises: an at least an impulse transmitting member; an at least a momentum varying member; a plurality of perforated members; a tectonic member; an at least a rooted member; a plurality of magnetic members; and an at least an angle of rotation sensing member.
Said at least one impulse transmitting member is associated with: said locomotory device’s suspension facilitating member, at one end of said at least one impulse transmitting member; and a detachable rim, at another end of said at least one impulse transmitting member. This configuration allows for removal of said rim, without dismantling said apparatus.
Said at least one momentum varying member broadly comprises a plurality of toothed members. Said at least one momentum varying member may be filled, with coolant oil. Said plurality of toothed members may include an at least a driving toothed member and an at least a driven toothed member.
One perforated member, among said plurality of perforated members, is for a propelling member, while another perforated member, among said plurality of perforated members, is for said at least one momentum varying member.
Said tectonic member is configured to provide (or is configured to bestow) structural integrity, to said propelling member (or upon said propelling member, or on said propelling member). Said tectonic member supports said propelling member.
An impulse generating portion of said apparatus broadly comprises: said at least one rooted member; an at least a pirouetting member; and said plurality of magnetic members. Said at least one rooted member is associated with said at least one pirouetting member. Said at least one rooted member is configured to broadly comprise a plurality of meandering members.
Each meandering member, among said plurality of meandering members, may be disposed on (or may be disposed at, or may be associated with) said at least one rooted member, at an outer portion (or an outer periphery, or an outer circumference) of said at least one rooted member.
Said at least one angle of rotation sensing member broadly comprises a second plurality of meandering members. Said second plurality of meandering members is communicatively associated with an at least a marshalling member. Said second plurality of meandering members transmits signals, to said at least one marshalling member. A throttle and/or a mode changer is/are associated with said propelling member.
Said apparatus may also comprise a plurality of rooted member slots. Said plurality of rooted member slots is laminated, for example, with amorphous metal alloys that have magnetic permeability and low core loss.
In operation, when said plurality of meandering members receives a supply, from a source, said plurality of meandering members becomes electromagnets and produces a uniform field. Although said source of supply is DC, switching generates an AC voltage waveform, with a trapezoidal shape. Due to interactions between said at least one rooted member and said at least one pirouetting member, said at least one pirouetting member rotates. Said plurality of magnetic members, with North and South poles, align with said at least one rooted member’s poles, causing rotation.
The disclosed apparatus offers at least the following advantages: is simple in construction; is cost-effective (costs about Rs. 21,000); offers a high efficiency; and/or provides strength to said locomotory device’s suspension facilitating member. Further, if said propelling member, fails, no damages occur to other components of said apparatus.

A side-mounted impulse generating apparatus, for a locomotory device (also referred to as “apparatus”), is disclosed. In an embodiment of the present disclosure, as illustrated, in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, and Figure 6, said apparatus is configured to be associated with a locomotory device’s suspension facilitating member (7; for example, a swing arm), for providing a smooth and comfortable ride, and broadly comprises an at least an impulse transmitting member (1; for example, a shaft).

A tectonic member (6) is configured to provide (or is configured to bestow) structural integrity, to the propelling member (17) (or upon the propelling member (17), or on the propelling member (17)). The tectonic member (6) supports the propelling member (17). For example, the tectonic member (6) is a frame.
The apparatus may communicate (for example, by means of signals), with other components of the locomotory device, through a plurality of communication facilitating members (for example, wires). For example, the plurality of communication facilitating members includes: an input positive communication facilitating member (8); an input negative communication facilitating member (9); and an I/O communication facilitating member (10). For example, the apparatus receives inputs (for example, of about 72 V), from an at least a power supplying member (for example, the locomotory device’s rechargeable battery).
As illustrated, in Figure 2, an impulse generating portion of said apparatus broadly comprises: an at least a rooted member (12; for example, a stator); an at least a pirouetting member (14; for example, a rotor); and a plurality of magnetic members (15; for example, twelve neodymium-type magnets or twelve neodymium magnets).
The at least one rooted member (12) is associated with the at least one pirouetting member (14). The at least one rooted member (12) is configured to broadly comprise a plurality of meandering members (13; for example, windings or coils).
Each meandering member, among the plurality of meandering members (13), may be disposed on (or may be disposed at, or may be associated with) the at least one rooted member (12), at an outer portion (or an outer periphery, or an outer circumference) of the at least one rooted member (12).
An at least an angle of rotation sensing member (16; for example, a resolver) broadly comprises a second plurality of meandering members (18; for example, windings or coils). The second plurality of meandering members (18) is communicatively associated with an at least a marshalling member (or an at least a controlling member; 25; for example, a microcontroller). The second plurality of meandering members (18) transmits signals, to the at least one marshalling member (25). A throttle and/or a mode changer is/are associated with the propelling member (17), for example, through signal wires. An example of how the same are controlled, for example, through the at least one marshalling member (25), is below:
Mode Direction of Rotation Throttle Voltage Speed
Reverse Reverse 0.8 V to 5 V 0 kmph to 4 kmph
Practice Forward 0.8 V to 5 V 0 kmph to 60 kmph
Drive Forward 0.8 V to 5 V 0 kmph to 90 kmph
Sports Forward 0.8 V to 5 V 0 kmph to 123 kmph

As illustrated, in Figure 4, the apparatus may also comprise a plurality of rooted member slots (20; for example, 12 slots). The plurality of rooted member slots (20) is laminated, for example, with amorphous metal alloys that have magnetic permeability and low core loss.
In another embodiment of the present disclosure, the electrical parameters of the apparatus are as follows:
Electrical Parameter Value or Range
Rated Voltage 72 V
Operating Voltage 60 V – 90 V
Rated Impulse 8 Nm
Rated Power 7 kW
Phase to Phase Winding Resistance 28 mO – 30 mO
Pole Pairs 5
No of Windings 12
No of Slots 12
Rated Speed 8,500 RPM
Rim Dimension 14 inches
Transmission ratio 1:8:22

In operation:
If a reference voltage V (R1–R2) is defined as VR, then the voltages, on the secondaries, are as follows:

? denotes shaft angle, VR denotes the reference voltage, VS denotes a secondary winding sin voltage, and VC denotes a secondary winding cos voltage.
Implicit arc tangent calculations (equation 3) are performed, on the at least one angle of rotation sensing member’s signals, by forcing a counter to track the position of the at least one angle of rotation sensing member (16). The Implicit arc tangent calculations are based on trigonometric identity.

Equation 4 says that the sine of the difference between two angles can be calculated, by cross multiplying the sine and cosine of the two angles and subtracting the results.
When the plurality of meandering members (13) receives a supply, from a source, the plurality of meandering members (13) becomes electromagnets and produces a uniform field. Although the source of supply is DC, switching generates an AC voltage waveform, with a trapezoidal shape. Due to interactions between the at least one rooted member (12) and the at least one pirouetting member (14), the at least one pirouetting member (14) rotates.
The plurality of magnetic members (15), with North and South poles, align with the at least one rooted member’s poles, causing rotation.
The disclosed apparatus has been tested. Impulse vs momentum data obtained was as follows:

15 7,500 25
16 8,000 24

As illustrated, in Figure 7, an efficiency of about 84% was obtained. This implies that the apparatus exhibits high reliability and impulse performance.
The disclosed apparatus offers at least the following advantages: is simple in construction; is cost-effective (costs about Rs. 21,000); offers a high efficiency; and/or provides strength to the locomotory device’s suspension facilitating member (7).
