Description
Technical field
The utility model relates to break technical field, particularly a kind of dual two leading shoe brake.
Background technique
Break, utilizes phase mutual friction between the rotatable member that is connected with vehicle body or vehicle frame to the trend of the rotation or rotation that stop wheel.Braking system can be divided into service braking sytem, parking braking system, secondary braking sytem and auxiliary braking system etc.Braking system in order to make the automobile in traveling underspeed even to stop is called service braking sytem; Then parking braking system is called in order to make the resident braking system as you were of the automobile of stagnation of movement; When driving a vehicle brake system non-functional, ensure that the braking system that automobile still can realize slowing down or stopping is called secondary braking sytem; When driving, auxiliary service braking sytem reduces the speed of a motor vehicle or keeps the speed of a motor vehicle to stablize, but the braking system of urgent for vehicle stop can not be called auxiliary braking system.In above-mentioned each braking system, service brake parking braking system of unifying is that each automobile is all prerequisite.But the braking system of prior art, generally can cause additional radial load to wheel hub, and Braking efficiency is lower when braking.
Chinese utility model patent CN 2755348Y discloses a kind of Double collar brake for motorcycle, comprise break object and two brake shoes, housing is provided with two camshafts coordinate with body clearance, two camshaft one end connect with two brake arms, and the other end is a bluff body; Be connected with two extension springs between two brake shoes, make two break two ends relatively abut in the bluff body both sides of two camshafts between two, brake shoe is fixed with braking plate.
Summary of the invention
The utility model technical issues that need to address.
For solving above-mentioned technical problem, dual two leading shoe brake of the present utility model comprises brake drum, wheel cylinder, braking bottom board, brake shoe, return spring, brake shoe, bearing, brake master cylinder, brake petal, push rod, master cylinder piston and oil pipe; Described braking bottom board is arranged on brake drum outer end; Described wheel cylinder is fixed on bearing upper end, and described brake shoe is provided with two panels on braking bottom board, and is connected by return spring; Described bearing is fixedly mounted on braking bottom board, and described master cylinder piston is arranged in brake master cylinder, and is connected with brake petal by push rod; Described oil pipe connects brake master cylinder and wheel cylinder.
Further, described wheel cylinder upper end is provided with adjusting nut.
Further, also comprise adjustable seats, described adjustable seats is fixed on side relative with wheel cylinder on brake drum.
Further, described brake shoe is connected with two return springs.
After adopting said structure, this dual two leading shoe brake, it belongs to balanced type break, and can not cause additional radial load to hub bearing, two-way Braking efficiency is high; Overall structure is simple, practical, is easy to promote the use of.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is brake drum, 2 is wheel cylinder, and 3 is braking bottom board, and 4 is brake shoe, and 5 is return spring, 6 is adjusting nut, and 7 is adjustable seats, and 8 is brake shoe, and 9 is bearing, and 10 is brake master cylinder, 11 is brake petal, and 12 is push rod, and 13 is master cylinder piston, and 14 is oil pipe.
Embodiment
As shown in Figure 1, a kind of dual two leading shoe brake of the present utility model, comprises brake drum 1, wheel cylinder 2, braking bottom board 3, brake shoe 4, return spring 5, brake shoe 8, bearing 9, brake master cylinder 10, brake petal 11, push rod 12, master cylinder piston 13 and oil pipe 14; Described braking bottom board 3 is arranged on brake drum 1 outer end; Described wheel cylinder 2 is fixed on bearing 9 upper end, and wheel cylinder 2 upper end is provided with adjusting nut 6; Described adjustable seats 7 is fixed on side relative with wheel cylinder 2 on brake drum 1; Described brake shoe 4 is provided with two panels on braking bottom board 3, and is connected by return spring 5; Described bearing 9 is fixedly mounted on braking bottom board 3.Described master cylinder piston 13 is arranged in brake master cylinder 10, and is connected with brake petal 11 by push rod 12; Described oil pipe 14 connects brake master cylinder 10 and wheel cylinder 2.
As further technological scheme of the present utility model: described wheel cylinder upper end is provided with adjusting nut.
As further technological scheme of the present utility model: also comprise adjustable seats, described adjustable seats is fixed on side relative with wheel cylinder on brake drum.
As further technological scheme of the present utility model: described return spring 5 is connected with two on connection brake shoe 4.
Working principle of the present utility model is as follows: when advancing braking, two brake shoes 4 and 8 are pressed against on brake drum 1 by all outwards movements under hydraulic pressure of all wheelcylinder pistons.Under the friction torque effect of brake drum, two hoof all rotate towards rotation of wheel direction around wheel center, are pushed back by the bearing 9 of two wheelcylinder piston outer ends, until lean wheel cylinder end face.Now the bearing 9 of two wheel cylinders becomes the fulcrum of brake shoe.
During reversing braking, the direction of friction torque is contrary, makes two brake shoes turn over an angle around wheel center O against the direction of arrow, by adjustable seats 7 together with adjusting nut 6 pushed home, so two bearings 7 just become the new supporting point of hoof.Like this, contrary when the position of the fulcrum of each brake shoe and small intestinal transit point is braked with advance, just the same when the same system of its Braking efficiency moves.
To those skilled in the art, but the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
