and a driving system for applying an elastic force to the brake disc 3 to make the brake disc 3 have a tendency to move toward the side close to the bracket 2, wherein the driving system comprises an electromagnet 42 capable of being powered on and powered off, and when the electromagnet 42 is powered on, the electromagnet applies an electromagnetic force to the brake disc 3 to make the brake disc 3 overcome the elastic force and separate from the first brake pad 21.
When the vehicle runs normally, the electromagnet 42 in the driving system is in an energized state, and the brake disc 3 is separated from the first brake pad 21 on the bracket 2 under the action of the electromagnetic force. At this time, the vehicle is not braked.
When braking is required, the electromagnet 42 in the drive system is in an off state, and the brake disc 3 loses the action of the electromagnetic force, and the brake disc 3 is in contact with the first brake pad 21 under the action of the elastic force applied thereto by the elastic force. At this time, since the axle 1 is rotatable relative to the brake disc 3, that is, the brake disc 3 is in a stationary state when the axle 1 rotates, the contact operation of the brake disc 3 with the first brake pad 21 on the carrier 2 generates a frictional force that hinders the axle 1 from continuing to rotate, thereby achieving braking.
In the preferred embodiment, the elastic body is a compression spring 41, and both ends of the elastic body are fixedly abutted to the brake disc 3 and the mounting disc 5, respectively.
More specifically, in this embodiment, the driving system includes a mounting disc 5 sleeved on the axle 1, the mounting disc 5 is located on a side of the brake disc 3 opposite to the bracket 2, the axle 1 can rotate relative to the mounting disc 5, the compression spring 41 is located between the mounting disc 5 and the brake disc 3, and the electromagnet 42 is fixedly connected to the mounting disc 5; the number of the compression springs 41 is multiple, the multiple compression springs 41 are uniformly distributed around the axis of the axle 1 at intervals, the axial end portion of the mounting disc 5 facing the brake disc 3 is provided with a counter bore 51 corresponding to the compression spring 41, one end of the compression spring 41 is accommodated and fixed in the corresponding counter bore 51, and the other end of the compression spring abuts against the brake disc 3. The structure can ensure the stress stability and uniformity of the brake disc 3 when the brake disc 3 is driven by the mounting disc 5, and the normal implementation of the braking action is ensured.
In this embodiment, the above-mentioned brake disc 3 and mounting disc 5 are all fixed mounting on the axle box to realize that the pivot can rotate relative to brake disc 3 and mounting disc 5, implementer can also play the same effect with brake disc 3 and mounting disc 5 fixed mounting on the shell of motor.
More specifically, an axial end of the mounting disc 5 facing the brake disc 3 is further provided with a receiving groove 52 for receiving the electromagnet 42, and in the present embodiment, the electromagnet 42 and the receiving groove 52 are both in a ring shape.
More specifically, in this embodiment, the brake device further comprises a controller and a micro switch 6 for monitoring whether the brake disc 3 and the mounting disc 5 are in a contact state or a separation state, and the micro switch 6 is electrically connected with the controller. Meanwhile, a toggle part 7 extending outward in the radial direction of the mounting plate 5 is formed on the side of the mounting plate 5. A toggle part 7 extending outwards along the radial direction of the mounting disc 5 is further formed on the outer side part of the mounting disc 5, the toggle part 7 is connected with a driving device (not shown) through a cable (not shown), the driving device can drive the mounting disc 5 and the brake disc 3 to move together along the axial direction through the cable and the toggle part 7 so as to be in contact with or separated from the first brake disc 21, and the control end of the driving device is electrically connected with a controller.
In addition, in the embodiment, a second brake pad 22 is fixedly arranged on the axial end of the bracket 2 facing away from the brake disc 3, and the second brake pad 22 is used for being in contact with the axial end of the other brake unit mounting disc 5 facing away from the counter bore 51 thereof when the electromagnet 42 is powered off or being separated from the axial end of the other brake unit mounting disc 5 facing away from the counter bore 51 thereof when the electromagnet 42 is powered on.
When the electromagnet 42 in the driving system is powered off, under the action of the elastic force of the compression spring 41, the axial distance between the mounting disc 5 and the brake disc 3 is increased, so that the mounting disc 5 and the brake disc 3 move in the direction away from each other, and the mounting disc 5 is in contact with the second brake pad 22 on the other brake unit bracket 2, so as to assist in braking and improve the braking effect of the whole brake unit. When the electromagnet 42 is energized, the mounting disc 5 receives the electromagnetic force and moves toward the brake disc 3, so that the axial distance between the two discs is reduced, and the second brake pad 22 is separated from the axial end of the other brake unit mounting disc 5 opposite to the counter bore 51.
The control method of the braking device provided by the embodiment specifically comprises the following steps:
obtaining each braking level of the braking device according to the number of the braking units participating in braking and the braking friction force of each braking unit participating in braking;
and obtaining the vehicle load, and obtaining the required safe braking force according to the vehicle load, so that the braking device adopts the correspondingly adapted braking level to perform safe braking.
In the embodiment, the implementing personnel can correspondingly adopt different brake levels according to different loads of the vehicle, so that the braking requirements of the vehicle for different loads are met, and the vehicle cannot slide due to overlarge braking force or stop within a safe braking distance due to undersize braking force.
The braking level is divided according to the total magnitude of the frictional force applied to the axle 1 by the braking units involved in braking. The act of obtaining the vehicle load may be manually input to the controller manually or the controller may be automatically obtained by a sensor.
Preferably, the control method further includes: when parking braking is carried out, the electromagnets 42 of all the braking units in the braking device are powered off, so that all the braking units carry out parking braking.
Meanwhile, after the controller receives the signal of the microswitch 6, whether the working state of the brake unit is normal or not can be judged. If the brake is abnormal, the controller controls the driving device to drive the mounting disc 5 and the brake disc 3 to move together, so that the brake is separated from the first brake pad 21 and locked by the driving device. And then, the controller adjusts the number of the brake units participating in braking again, and further adopts the corresponding brake level capable of meeting the braking requirement again.
In addition, during the operation of the vehicle, if the controller receives a signal that the first brake pad and the brake disc 3 of the brake unit not participating in braking are accidentally contacted, the vehicle is automatically unloaded. When the vehicle is started, if the brake units are not completely released, namely the system sends a closing signal, the vehicle cannot be loaded and run; the controller is also provided with a slope starting function, after the function is started, the controller automatically applies slope starting braking force according to the slope and the load, and the braking device selects the corresponding braking level to brake.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
