Abstract
The utility model discloses a permanent magnet brake, which mainly comprises a static disc, a moving disc which can rotate relative to the static disc, and a main shaft, wherein a certain space is provided at the engaging portion of the static disc and the moving disc, and the circumferential plane surfaces of two discs are provided with grooves which are respectively provided with permanent magnetic blocks which are surrounded by magnetic insulating material. The opposite surfaces of the upper magnetic block and the lower magnetic block have the same magnetic poles. A magnetic torque which is opposite to the rotating direction of the main shaft can be produced, thereby realizing the purpose of braking and moving by utilizing permanent magnet.
Description
One, affiliated technical field
The utility model belongs to little torque machine motor vehicle, brakes such as motorcycle, rickshaw.
Two, background technique
At present, the manual brake device mainly contains disc brake, wheel formula brake etc.Its skidding principle is to utilize the frictional force between a pair of brake pad and disc wheel wheel rubbing surface to realize braking brake.Shortcoming is that frictional noise is bigger, complex structure, and manufacturing cost height, working life is shorter.
Three, summary of the invention
This novel goal of the invention provides a kind of energy and solves above-mentioned deficiency, and utilizes magnetic force realization power brake between the permanent magnet magnetic pole, and has simple in structure, noiseless, the permanent magnet brake of long service life.
For realizing goal of the invention, take following technology technically: this permanent magnet brake, it comprises quiet dish, the hole is combined with the Moving plate and the main shaft of its axial motion relatively within it, its Moving plate be provided with certain interval between quiet dish cooperates, and be equipped with groove apart from axis e place at Moving plate and quiet dish circumferencial direction plane place, also in its each groove, be provided with the permanent magnet magnetic patch, its magnetic patch is provided with the NULL cover outward, when described Moving plate is corresponding with the magnetic patch on the quiet dish, two magnetic patch surface magnetic pole with gap is identical, forms the vertical magnetic line of force.
This novel compared with prior art beneficial effect is as follows:
A, this brake mainly are to be equipped with a plurality of corresponding and two magnetic on Moving plate and quiet dish
The identical magnetic patch of the magnetic pole of face mainly is to utilize repulsive force between the permanent magnet, produces and Moving plate
The moment of torsion that sense of rotation is opposite has been realized contactless power brake, thus noiseless; Increase
The strong performance of brake, also extend working life.
B, this brake mainly are made of a pair of coaxial dynamic and static dish, with above-mentioned disc brake,
Wheel formula brake is compared to have simple in structurely, safe, and easily realizes on the technology.
Four, description of drawings
Fig. 1 is this new structure sectional view;
Fig. 2 is this novel user mode figure.
Five, embodiment
Referring to Fig. 1～2, this brake mainly is made of Moving plate 1, quiet dish 2, main shaft 6.Be configured on the wheel wheel of said various vehicles.Its Moving plate 1 circumferential plane place evenly is provided with groove 7 apart from axis e place, and in groove 7, be provided with permanent magnet magnetic patch 4, this magnetic patch surrounds in the Moving plate 1 of packing into NULL cover 5, quiet dish 2 circumferencial directions are apart from axis e place, the corresponding part that is Moving plate 1 each groove evenly is provided with the groove 8 identical with Moving plate upper groove number, and in its each groove 8, also surround by NULL cover 5 and insert in the quiet dish 2, it is described that magnetic patch 3,4 opposing side magnetic poles are identical in pairs up and down.Moving plate 1 has certain clearance with quiet dish 2 cooperation places, has certain clearance to form relative two magnetic patch, 3,4 opposing sides.
The working principle of this brake
(as shown in Figure 2) Moving plate 1 is in outside quiet dish 2 endoporus under normal operation, double dot dash line A position.When the needs braking brake, can Moving plate 1 be moved to left to quiet dish 2 holes by shift fork 9, Moving plate 1 rotates in quiet dish 2 holes, when the permanent magnet magnetic patch 4 on the Moving plate 1 is corresponding with permanent magnet magnetic patch 3 magnetic poles on the quiet dish 2, produce repulsive interaction and make it to form and the opposite moment of torsion of main shaft 6 sense of rotation, thus the purpose of realization brake.The brake back moves to right to original position A place Moving plate 1 by shift fork 9 again, and Moving plate 1 can continue rotary work with main shaft 6.
Claims (1)
1, a kind of permanent magnet brake is characterized in that: it comprises quiet dish (2), the hole is combined with the Moving plate (1) and the main shaft (6) of its axial motion relatively within it; Its Moving plate be provided with certain interval between quiet dish cooperates, and locate to be equipped with groove (7 apart from axis (e) at Moving plate (1) and quiet dish (2) circumferencial direction plane place, 8), also in its each groove, be provided with permanent magnet magnetic (3,4), its magnetic patch is equipped with NULL cover (5) outward, when described Moving plate (1) is corresponding with the magnetic patch on the quiet dish (2), two magnetic patch surface magnetic pole with gap is identical, forms the vertical magnetic line of force.
