Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an energy-saving linear motor-propelled track vehicle that utilizes a flywheel to absorb energy during deceleration or braking of a vehicle and release it during propulsion of the vehicle.

The present invention converts surplus linear kinetic energy of a vehicle into rotational kinetic energy by means of tires rolling in contact with a lateral guide track, and converts this energy into rotational kinetic energy by a differential gear and clutches connected to shaft systems at both ends thereof.・
It is absorbed and stored in one of a pair of flywheels via a brake device and a transmission device, and is released when the vehicle accelerates, and the other flywheel rotates at a low speed or stops in preparation for vehicle deceleration. It is constructed so that it can absorb energy.

Hereinafter, the structure of the present invention will be explained based on the illustrated embodiment. FIG. 1 is a schematic configuration diagram of a linear motor propulsion track vehicle, in which a primary winding 33 of a linear motor propulsion device is installed at the bottom of a vehicle body 31. A secondary conductor 34 is installed on the track side or vice versa. car body 3
A sliding shoe 35 is also attached to the bottom of 1,
It is designed to slide on a sliding track 37.

The feature of the present invention is that a guide wheel 2 is attached to the side of the vehicle body 31 and rotates in contact with a lateral guide track 36.
2, and an energy recovery device 30 coupled to this shaft portion is attached to the vehicle body.

As is clear from FIG. 2, the energy recovery device 30 includes a wheel 22, a differential gear device C configured therein, and shafts 13 and 13a that support opposing bevel gears of the differential gear device C. The provided clutch/brake device B and the bevel gear shafts 13, 13
The planetary gear transmission A includes a planetary gear transmission A, each of which has one rotating terminal connected to each terminal, and a flywheel 7, which is supported by the other rotating terminal of the planetary gear transmission.

A hub 24 that supports the wheel 22, specifically the tire.
is connected to the support body 21 by a spline 27 so as to be able to slide slightly in the axial direction, and a plurality of bevel gears 16 are supported on the cylindrical portion of the support body 21 by a shaft 17 in the radial direction. A pair of meshing bevel gears 2
0, 20a is attached to the shaft 13, 13a with bolts 19, 19
It is fixedly supported at a. The clutch/brake device B, the transmission A, and the flywheel supported by each shaft 13, 13a are completely symmetrically constructed, and the system of the bevel gear shaft 13a is indicated by adding "a" to the end of each symbol. The explanation will be omitted.

A spline 14 is formed on the shaft 13, and an axially slidable wheel 11 is supported on the spline 14. Circium 1
A friction material 29 with high wear resistance is adhered to the outer peripheral surface of the piston 1, and when the brake shoe 39 at the tip of the piston 2 protrudes from the hydraulic cylinder 1 attached to the casing 10 side is frictionally engaged. 13 is now braked. Permanent magnets 15 are arranged at intervals in the circumferential direction on the end surface of the ring body 11,
When the repulsive electromagnet 3 constituting the magnetic clutch is demagnetized, the wheel 11 approaches the support ring 23 by the force of the compression spring 18 interposed between the bevel gear 20 and the wheel 11. The support ring 23 has a bearing 12 at the end of the shaft 13.
It also supports a plurality of planetary gears 5 via a shaft 6. This planetary gear 5 meshes with the internal gear 4 configured in the casing 10, while
It meshes with the sun gear 9 of the shaft 7. A flywheel 8 is fixedly supported on the shaft 7. Shaft 7 is bearing 2
It is supported by the casing 10 via 6 and 28.
A thrust bearing 26 is interposed between the shaft 7 and the shaft 13.

Next, the operation of the energy-saving rail vehicle according to the present invention will be explained. Repulsion type electromagnet 3 shown in Fig. 2
is excited, the running wheels 22 of the vehicle
rotates in contact with the guide track 36, and the shafts 13, 13a
Rotate at the same speed and in the same direction. At this time, the wheels 22 only guide the vehicle body in the left and right direction. Now, when trying to decelerate the vehicle, one brake, for example, the shoe of the piston 2a, is frictionally engaged with the outer peripheral surface of the wheel body 11a to stop the rotation of the wheel body 11a.
Since the shaft 13a and the bevel gear 20a both stop, the bevel gear 20 is accelerated as the bevel gear 16 rotates about the shaft 17, and the ring 11 of the shaft 13 is rotated at high speed. Here, when the electromagnet 3 is demagnetized, the force of the spring 18 causes the wheel body 11 to approach the support ring 23, eddy current is induced in the support ring 23, and the wheel body 11 is brought closer to the support ring 23.
1 is transmitted to the support ring 23, and the rotational force of the planetary gear 5 is transmitted to the support ring 23.
is rotated, the shaft 7 of the sun gear 9 is rotated in the same direction at a higher speed than the shaft 13, and the flywheel 8
The inertial kinetic energy of the vehicle is stored as rotational energy, while the vehicle is decelerated. As described above, for one bevel gear shaft system of the differential gear C configured inside the wheel, the clutch/brake device A consisting of the wheel 11, the piston 2, the electromagnet 3, and the spring 18 is put into the braking state, and the other one is put into the braking state. With respect to the bevel gear shaft system, by bringing the clutch/brake device A into the clutch engaged state, the other bevel gear shaft system is rotated, the speed is increased by the transmission device A, and the speed is absorbed by the flywheel.

When the electromagnet 3 is excited, the ring body 11 moves to the support ring 23
The rotational connection is released. The flywheel 8 continues its rotational motion and conserves energy.

When the vehicle needs to be further decelerated, such as when traveling down a steep and long downhill slope, the brake applied to the wheel 11 by the piston 2 is released while the brake applied to the wheel 11 is applied by the piston 2.
The bevel gear 20 stops, and the bevel gear 20a rotates at an increased speed. Then, when the electromagnet 3a is demagnetized and the wheel body 11a and the support ring 23a are rotationally coupled, the rotational force of the wheel 22 is absorbed by the flywheel 8a as in the case described above. When the vehicle body is to be completely stopped, each electromagnet 3, 3a is energized to release the clutch connection, and the pistons 2, 2a are used to stop the wheel body 11,
If the brakes 11a are applied at the same time, braking force is applied to the wheels 22.

Next, when starting or accelerating the vehicle, one of the wheels 11, 11a is braked by the piston 2 or 2a, and the other wheel is rotationally connected to the support ring, and one flywheel The rotational force of is transmitted to one of the bevel gears 20, 20a, while the other remains stationary, so the wheels 22 are driven with the rotation of the bevel gear 16, working to propel the vehicle body, and the external power (linear motor propulsion power) can be saved. The rotational speed of the flywheel used for this acceleration is reduced to prepare for energy absorption during the next deceleration of the vehicle. In addition,
The rotational speed of the wheels 22 during acceleration can be smoothly controlled by adjusting the braking force applied to one of the bevel gear shaft systems.

As explained above, in the present invention, the inertial running energy of the vehicle is absorbed and stored as rotational energy in one of the pair of flywheels via the differential gear device configured inside the wheels, and when the wheels accelerate, Since the other flywheel is provided for energy absorption in case of deceleration operation of the vehicle, the power required for operating the vehicle can be significantly reduced.

In the above embodiment, instead of the magnetic clutch, the wheel body 11 and the support ring 23 may be rotationally coupled by an electromagnetic clutch or a friction clutch. Also, the bevel gear 1 supporting the wheel 22
3 and 13a are supported slightly tilted forward rather than perpendicular to the running surface of the vehicle, thereby suppressing vibrations of the vehicle, especially lifting caused by vibrations, and supporting the primary winding of the linear motor propulsion device. lines 33 and 2
Since the gap change with the secondary conductor 34 can be suppressed and maintained at a minimum, high propulsion efficiency can be obtained.
