Problems solved by technology

The disadvantage is that when the friction rod is running on the track curve, the positional relationship between the friction rod and the driving wheel will also change in real time due to the continuous change of the direction of the friction rod.
The position of the driving wheel of the above-mentioned non-contact magnetic drive device is fixed, and the position between the friction rod and the driving wheel cannot be adjusted in real time, resulting in insufficient or invalid driving of the friction wheel to the friction rod when the friction rod is running on a curved track of the friction rod.
Moreover, the magnetic force of the above-mentioned non-contact magnetic drive device cannot be adjusted, so it cannot meet the demand for variable driving force in production.

Embodiment Construction

[0017] The accompanying drawings describe the composition, structure and principle of the contact electromagnetic drive device of the present invention. The following will introduce in detail:

[0018] figure 1 The middle friction rod 2 is made of iron material, and moves along the track after being connected with the rail car. The driving wheel core 5 is driven to rotate by the motor 6 installed above it. The outermost layer of the driving wheel core 5 is wrapped with a friction material layer 3 for increasing the friction force when in contact with the friction rod 2 .

[0019] The distribution of the whole contact electromagnetic drive system is as follows: figure 2 As shown, several friction wheel guide rails 12 are sequentially installed along the inner side of the curve of the friction bar track 1 , and the friction wheel guide rails 12 are located on the normal direction of the curve of the friction bar track 1 . When the friction rod 2 is located on the friction ...

Abstract

The invention relates to contact type electromagnetic driving device and method, belonging to the technical field of electromagnetic driving. The device comprises a friction wheel guide rail (12), an installing frame (7), a motor (6), a friction wheel assembly, a resetting frame (9), a first electric magnet (10) and a second electric magnet (8), wherein the friction wheel assembly sequentially comprises a wheel core (5), a coil winding layer (4) and a friction material layer (3) from inside to outside. Repulsion force or attraction force of different magnitude, which is generated between the first electric magnet (10) and the second electric magnet (8), drives the installing frame (7) and the friction wheel assembly to move on the friction wheel guide rail (12), thereby tightly attaching the friction material layer (3) of the friction wheel assembly to a friction bar (2) at constant pressure, and overcoming the defect that the pressing force of a driving wheel to the friction bar can not be regulated in real time.

Description

technical field [0001] The contact electromagnetic driving device and method involved in the present invention can replace the existing contact mechanical force clamping and non-contact magnetic driving devices, and can be used to drive railcars with iron friction rods without power, which belongs to the electromagnetic drive technology field. Background technique [0002] The patent application No. 200810021612.3 proposes a non-contact magnetic drive device for driving various self-powered railcars, replacing the friction drive device of the existing friction-driven railcars. Its advantages are non-contact friction drive based on the principle of magnetic coupling, its structure and process are relatively simple, and its production cost is low. Its disadvantage is that when the friction rod is running on the track curve, the positional relationship between the friction rod and the driving wheel also changes in real time due to the constant change of the direction of the fr...
