Abstract
The utility model discloses a disk-forceps type braking device provided with a pair of rotary forceps, which belongs to the technical field of disk-forceps type braking and aims to overcome the deficiencies that a larger braking-actuating force is needed by a present disk-forceps type braking device, the braking moment enhanced by increasing the braking-actuating force is also difficult to meet the requirement on the effective braking for a vehicle running at a high speed, and the like. The disk-forceps type braking device comprises a braking disk and is provided with a braking ring, the rotary forceps and a fixed shaft, wherein the braking ring and the braking disk are fixedly connected through a fixed part or manufactured into a whole, one end of the rotary forceps is rotatably installed on the fixed shaft, a pull rod is installed at the other end of the rotary forceps, and at least two forceps hooves are arranged on the rotary forceps. The disk-forceps type braking device is applicable to equipment, such as high-speed automobiles, high-speed trains and the like which are braked by needing larger braking moments.
Description
Technical field
The utility model relates to a kind of dish and clamps down on braking technique, particularly relates to a kind of dish caliper brake device that rotates pincers that is provided with.
Background technique
On vehicle, want the arrangement brake device all essentially, through long term studies and improvement, the braking device of existing a lot of patterns can be selected for people.The dish caliper brake device is owing to have lot of advantages, and for example: general nothing friction helps gesture effect, its usefulness to be subjected to the influence of friction factor less, that is to say that usefulness is more stable; Have when brake area under the situation of water, usefulness reduces less, recovers normal very fast; Under the identical situation of output braking moment, size and quality are less, more economize with material; Brake disc is minimum along the thermal expansion amount of thickness direction, can obviously not influence the increase and decrease of brake clearance; The M R operation is easier or the like; So, be widely used.But, also there is the bigger deficiency of required brake actuation power in dish jaw type system device, especially under the situations of expressway, a large amount of appearance of high-speed railway at present, the travelling speed of vehicle improves exponentially, motion inertia force is extremely huge, only can't satisfy the needs that the vehicle of high speed operation is effectively braked with the braking moment that frictional force strengthened that improves brake actuation power and then strengthen between brake disc and the brake shoe.
Summary of the invention
The purpose of this utility model provides a kind of dish caliper brake device that rotates pincers that is provided with, overcoming present dish caliper brake device needs brake actuation power bigger, and the braking moment that is strengthened with raising brake actuation power also is difficult to satisfy the deficiencies such as needs that the vehicle of high speed operation is effectively braked.
The utility model is achieved by following technical proposals.
The utility model comprises brake disc, be provided with trig loop, rotate pincers, stationary axle, described trig loop is fixedlyed connected with fixed block with described brake disc or is made as a whole, one end of described rotation pincers is loaded on the described stationary axle rotationally, the other end is equipped with pull bar, is provided with two pincers hoof on the described rotation pincers at least.In the design of the present utility model, on end face of described brake disc, set up described trig loop, on the simultaneously described rotation pincers relative position is housed and is fixing pincers hoof, described pincers hoof is established two, place with a gap respectively described brake disc do not establish on the end face of described trig loop and the inner ring of described trig loop on.Because when implementing braking, it is the center rotation with described stationary axle axle center that described pull bar spurs described rotation pincers, makes described pincers hoof press to described brake disc and trig loop, produces very big frictional force.Simultaneously, the pressure of described pincers hoof makes described brake disc and trig loop produce local deformation, and deformation described brake disc and trig loop and described pincers hoof between resistance appears extraly, and this resistance ratios frictional force is bigger, and their stack backs produce very powerful braking moment.
Being connected as fixedly connected with fixed block of described trig loop and described brake disc, described fixed block is a rivet, and perhaps described fixed block is a bolt and nut.Destroyed under the impact of huge braking moment in order to prevent described rotation pincers, the both sides of described rotation pincers are provided with the retaining tong holder.
Against existing technologies, the beneficial effects of the utility model are:
Under the identical situation of brake actuation power, can improve braking moment exponentially.
Reduced dependency degree, their surface abrasion degree is slowed down, prolonged the cycle of repair and replacement, reduced user cost frictional force between brake disc and the brake shoe.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation, and Fig. 2 is that the A of Fig. 1 is to view.Among the figure: 1, brake disc, 2, trig loop, 3, rotate pincers, 4, stationary axle, 5, fixed block, 6, pull bar, 7, the pincers hoof, 8, the retaining tong holder.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Embodiment as shown in the figure, trig loop 2 is fixedlyed connected with brake disc 1 usefulness fixed block 5.When not adopting braking, brake disc 1 high speed rotating does not contact with other parts such as brake calipers 3, pincers hoof 7.When needs were braked, it was that a center rotates counterclockwise that brake actuation power clamps the 3 axle centers with stationary axle 4 by pull bar 6 pulling rotations, and pincers hoof 7 presses to brake disc 1 immediately and trig loop 2 produces very big frictional force.Simultaneously, the pressure of pincers hoof 7 makes trig loop 2 and brake disc 1 produce local radial and axial deformation, and the surface of the surface of these deformation and pincers hoof 7 can produce huge resistance when slide relative.The braking moment that makes brake disc 1 rapid stall has just been synthesized in the stack of above-mentioned two bursts of power.The reaction force of powerful braking moment will inevitably put on and rotate on the pincers 3, is provided with retaining tong holder 8 in the present embodiment and gives to absorb fully, has guaranteed to rotate pincers 3 and has not been damaged.
