Technical Field

The invention relates to the technical field of automobile brakes, in particular to a new energy automobile brake.

Background

The guide tube 711 is cylindrical and is screwed to the closed end of the inner cavity of the housing 713; the guide tube 711 extends in the axial direction of the housing 713.

The restoring member 72 includes a tubular extension tube 722 and a retainer ring 721. The collar 721 is annular and is screwed to the end of the bellows 722. The second spring 712 is bound at a closed end of the housing 713, and the other end of the second spring 712 is bound to an edge of the retainer ring 721. A plurality of second springs 712 surrounds the guide tube 711 on the circumferential side.

During braking, the two seesaw rods 1 approach each other, the telescopic tube 722 slides towards the outer shell 713 along the axial direction of the outer shell 713, the retainer ring 721 slides along the axial direction of the outer shell 713 in the inner cavity of the outer shell 713, meanwhile, the telescopic tube 722 slides along the guide tube 711, and the retainer ring 721 presses the second spring 712. Due to the existence of the second spring 712, the retainer ring 721 is prevented from directly impacting the end of the housing 713, and the second spring 712 plays a role in buffering and a good protection role.

When the brake is released, the telescopic tube 722 slides out of the outer shell 713 along the axial direction of the outer shell 713, the retainer ring 721 pulls the second spring 712, the second spring 712 plays a role in drawing the retainer ring 721, the retainer ring 721 is prevented from directly sliding to an outlet of the end of the outer shell 713, the retainer ring 721 is prevented from directly impacting the outer shell 713, and a buffer protection effect is achieved.

The working principle of the invention is as follows:

when using, anchor clamps 4 drive transverse connection spare 3 simultaneously and rotate to the internal contraction under the exogenic action, and transverse connection spare 3 rotates the lower extreme that the pole 1 was stuck up in the pulling simultaneously and rotates round connecting piece 2, and two stick up the pole 1 and rotate round connecting piece 2 respectively and two stick up the lower extreme of pole 1 and be close to each other, and two stick up the lower extreme of pole 1 and drive splint 5 and the friction part 6 that are in on it respectively and be close to each other when being close to each other, and final two friction parts 6 are close to each other and the wheel hub that extrudes the wheel realizes brake.

When the automobile wheel is installed, the distance between the body 52 and the bearing plate 61 is adjusted by rotating the first screw 55 according to the width of the wheel hub and the magnitude of acting force required to be applied during braking, and further the depth of the extrusion block 62 extending into the installation groove 51 is adjusted. When the pressing plate 64 presses against the wheel hub surface, the force acting against the body 52 is transmitted to the spacer 53 and the first spring 56, and the spacer 53 and the first spring 56 deform under the pressing to provide a cushion protection.

During braking, the extrusion plate 64 firstly contacts with a hub of a wheel, the main plate 6444 is made of rubber materials, and the main plate 6444 can deform when being extruded, so that a part of extrusion force is absorbed, and a buffering effect is achieved. When the main plate 6444 is in contact with the outer surface of the wheel hub, the relative speed between the main plate 6444 and the outer surface of the wheel hub can generate transverse extrusion force on the surface of the main plate 6444, and after the transverse extrusion force acts on the main plate 6444, the buffer groove 6441 can be bent and deformed towards the inner cavity of the buffer groove to relieve the transverse extrusion force, so that the buffer groove can play a role in buffering and protecting the main plate 6444.

The convex pieces 6443 and the convex points 6442 are extruded on the surface of the vehicle hub, the convex pieces 6443 and the vehicle hub are in point contact, acting force is concentrated on the points, the extrusion effect is large, under the condition that the friction coefficient of the material of the main plate 6444 is not changed, the friction force can be improved by increasing the extrusion acting force, and the braking effect is good. The convex pieces 6443 are small and round, the contact surface is not large, the extrusion force can be concentrated on a small surface, the extrusion effect is increased, the transverse friction force is increased, and the braking effect is good.

The pressing forces transmitted to the first pressing block 641 and the second pressing block 643 through the plate body 644 are made of steel, and when the pressing force perpendicular to the plate body 644 is large, the first pressing block 641 and the second pressing block 643 can bear large acting force, so that the bearing capacity of the pressing plate 64 is improved, and the safety and the stability of the pressing plate are ensured. When the first pressing block 641 and the second pressing block 643 receive lateral pressing force, both the first pressing block 641 and the second pressing block 643 press the rubber layer 642, and the rubber layer 642 deforms to absorb the pressing force, thereby playing a role of buffering protection.

In the braking process, main block 621 and snubber block 622 are placed in mounting groove 51, and the lateral extrusion force of acting on body 52 can transmit snubber block 622, and a plurality of snubber blocks 622 adopt the combination of disconnect-type structure, compares in the condition of single monolithic structural design, and when snubber block 622 received lateral extrusion force, thereby every snubber block 622 all can produce corresponding deformation and absorb the extrusion force, plays the cushioning effect, avoids single snubber block 622 to receive the too big problem that produces deformation and damage of extrusion force.

The damping layers 6221 are made of rubber materials, and two adjacent damping layers 6221 are matched with each other through concave-convex curved surfaces. At the position where the two shock absorbing layers 6221 contact each other, the pressing force acting on the shock absorbing layers 6221 is dispersed along the curved surface at the contact position and is dispersed in different directions, avoiding stress concentration. The multiple shock absorbing layers 6221 are combined with each other, and each shock absorbing layer 6221 can be deformed to absorb the compression for protection.
