Abstract
A caliper brake for automobiles comprises a brake caliper, a brake disc, a piston, a piston seal ring, friction blocks, bottom plates of the friction blocks, circumferential positioning pins of the friction blocks and the like. Each of two side surfaces of the brake disc is provided with a circular groove, the two circular grooves are the same and concentric with the brake disc, and the cross section of each circular groove is in the shape with two symmetric and inclined side edges. Each friction block is provided with a protruded ring in the shape matched with that of each circular groove of the brake disc, and a clearance is reserved between the top surface of the protruded ring of each friction block and the bottom surface of each circular groove of the brake disc the after two side surfaces of the protruded ring of each friction block fit with two side surfaces of each circular groove of the brake disc. The caliper brake for automobiles has high braking force without requirement for increasing the diameter of the brake disc or increasing hydraulic power.
Description
Affiliated technical field
The utility model relates to a kind of automotive brake, refers to a kind of caliper disc automotive brake especially.
Background technique
Present known caliper disc automotive brake has that the influence that Braking efficiency changes by friction factor is little, and thermal diffusivity is good, and heat resistanceheat resistant decline property is good, and the restorative advantage such as good in the back of paddling.It is not enough, and point is that brake braking force is not high.The caliper disc automotive brake of existing structure will obtain higher brake braking force, need realize with modes such as improving hydraulic coupling through strengthening the brake disc diameter.But the brake disc restricted diameter is in the physical dimension of automobile itself, and higher hydraulic coupling will be arranged, and will increase the complexity of hydraulic system, and is prone to make the functional reliability of hydraulic system to descend.
Summary of the invention
In order to overcome the not high shortcoming of brake braking force of existing existing caliper disc automotive brake, the utility model provides a kind of caliper disc brake, and this break need not to strengthen the brake disc diameter and has higher brake braking force with improving hydraulic coupling.
The utility model solves the technological scheme that its technical problem adopted: the caliper disc brake that is designed comprises parts such as braking clamp body, brake disc, piston, piston packing, brake pad, brake pad base plate and the circumferential locating stud of brake pad; Brake disc and wheel are solidly installed; Braking clamp body is installed on stub axle or the axle housing; The piston cunning is loaded in the braking clamp body, and an end of piston connects the brake pad base plate, is fixed with brake pad on the brake pad base plate; The brake pad base plate slides on the circumferential locating stud of brake pad; The circumferential locating stud of brake pad is installed on the braking clamp body, and piston packing is loaded in the braking clamp body, all has identical on the card of brake disc both sides and concentric with a brake disc circle annular groove; The side that the shape of cross section of this annular groove has two symmetries and tilts; Brake pad has one section bulge loop with said brake disc annular groove form fitting, and after fitting in the bi-side of the bi-side of brake pad bulge loop and brake disc annular groove, the bottom surface of the end face of brake pad bulge loop and brake disc annular groove has the gap.
The principle that this programme adopts is, when brake pad is promoted the compacted applying in bi-side of the bi-side of brake pad bulge loop and brake disc annular groove by the piston level.Because brake pad bulge loop laterally inclined, its suffered normal force just can be used for the horizontal thrust that the balance brake pad receives piston with horizontal thrust piston component in the same way, therefore described normal component of force is greater than the horizontal thrust of piston.Like this, have the gap as long as accomplish the end face of brake pad bulge loop in the using process and the bottom surface of brake disc annular groove, less piston horizontal thrust just can make the side of brake disc annular groove receive big positive pressure, also just can obtain bigger brake braking force.
The beneficial effect of the utility model is that this break need not to strengthen the brake disc diameter and has higher brake braking force with improving hydraulic coupling.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model embodiment's a plan view.
Fig. 2 is a brake disc partial view embodiment illustrated in fig. 1.
Fig. 3 is that the A of Fig. 2 is to view.
1. braking clamp bodies among the figure, 2. piston packing, the 3. circumferential locating stud of brake pad, 4. brake pad base plate, 5. piston, 6. brake disc, 7. brake pad.
Embodiment
In Fig. 1, Fig. 2 and embodiment shown in Figure 3; Brake disc (6) is solidly installed with wheel (not drawing among the figure), and braking clamp body (1) is installed on stub axle or the axle housing (not drawing among the figure), and piston (5) is sliding to be loaded in the braking clamp body (1); One end of piston (5) connects brake pad base plate (4); Be fixed with brake pad (7) on the brake pad base plate (4), brake pad base plate (4) slides on the circumferential locating stud of brake pad (3), and the circumferential locating stud of brake pad (3) is installed on the braking clamp body (1); Piston packing (2) is loaded in the braking clamp body (1); All have identical on the card of brake disc (6) both sides and concentric with brake disc (a 6) circle annular groove, the side that the shape of cross section of this annular groove has two symmetries and tilts, brake pad (7) has one section bulge loop with said annular groove form fitting; After fitting in the bi-side of the bi-side of brake pad (7) bulge loop and brake disc (6) annular groove, the bottom surface of the end face of brake pad (7) bulge loop and brake disc (6) annular groove has the gap.During braking, brake pad (7) is promoted by piston (5) level, the compacted applying in bi-side of the bi-side of its bulge loop and brake disc (6) annular groove.Because brake pad (7) bulge loop is laterally inclined; Just being used for balance brake pad (7) with piston horizontal thrust component in the same way and receiving the horizontal thrust of piston (5) of the normal force that it is suffered; Like this; Less piston (5) horizontal thrust just can make the side of brake disc (6) annular groove receive big positive pressure, also just can obtain bigger brake braking force.
Undoubtedly, present embodiment also has the various deformation structure.For example with also making two circle annular grooves on the brake disc (6), brake pad (7) is also processed two sections suitable with it bulge loops.For another example, the annular groove on the brake disc (6) is become bulge loop, and brake pad (7) bulge loop is become annular groove.In a word, the scope of the utility model protection also should comprise conspicuous other distressed structures of these those skilled in the art.
