Abstract
A drum type brake device comprises a brake block and a brake drum; the brake block is static in the brake drum; the brake drum rotates along with the rotation of wheels; the friction surface of the brake drum is provided with at least one annular groove; the friction surface of the brake block is the surface which is matched with the annular groove. According to the drum type brake device, the friction surface is provided with the groove and accordingly the friction area is increased and the large stamping power or oil pressure is not required; the brake power can be improved without a large diameter of brake drum; when an annular V-shaped groove is matched with annular V-shaped protruding ribs and the annular V-shaped groove completely abuts against the annular V-shaped protruding ribs, namely that included angles of the annular V-shaped groove and the annular V-shaped protruding ribs are the same, a numerical value of the average width of the V-shaped protruding ribs is slightly larger than that of the average width of the V-shaped groove, the top ends of the V-shaped protruding ribs are circular arcs, and accordingly the large clamping force can be produced by the groove as long as the V-shaped protruding ribs slightly move forward and accordingly effective braking can be performed. The condition that an annular trapezoidal groove is matched with annular trapezoidal protruding ribs is the same as the condition that the annular V-shaped groove is matched with the annular V-shaped protruding ribs.
Description
Technical field
The present invention, for being mainly used in brake and drive system for vehicle with tow, also can be used for the brake system of other rotatable parts, is exactly specifically, has the ironcasting of the similar tambourine of a shape, is called brake drum, and it and tire are fixed and synchronized rotation; When brake, use oil pressure to promote brake block (Brake Shoes) contact brake drum inner edge, the rotation that the friction producing by contact suppresses tire is to reach a kind of drum type braking device of object of brake.
Background technique
Briefly, drum brakes is exactly to utilize static brake block in brake drum, removes the brake drum of friction along with vehicle wheel rotation, to produce the turn a wheel braking device of Speed Reduction of frictional force.In the time stepping on braking pedal, the application of force of pin can make the piston in general braking pump brake oil be pushed and produce pressure forward in oil circuit.Pressure is sent to the wheel cylinder piston of each wheel via brake oil, it is outside that the piston of wheel cylinder promotes brake block again, and the inner face of brake block and brake drum is rubbed, and produces enough friction and go to reduce the rotating speed of wheel, to reach the object of brake.
Rouse the good effect of certainly stopping of stopping, because brake lining is opened outward, rotation of wheel is inconjunction with outside outer angle of brake drum distortion (surely not drawing to allowing you be easy to see greatly) brake lining of opening
tension force(brake control power) is larger, and situation is just more obvious, therefore, general large vehicle still uses drum to stop, and except cost is lower, the drum of large car and compact car is stopped, difference may be venerated large-scale gas production dynamic auxiliary, and compact car adopt vacuum aided help brake.But, the overload of Chinese large-sized car is general, original drum is stopped and can not be adapted to for a long time overload situation, and the design of vehicle has overall relevance, just so large for the stop space that stays of drum, will change many designs if need to increase space, so stopping, can not blindly strengthen by the drum of large car, the space of how to stop at existing drum increases the braking force that drum is stopped, and is the problem that needs solution.
Summary of the invention
The problem that increases the braking force that drum stops in order to solve space that large car stops at existing drum, the invention provides a kind of drum type braking device.
The present invention is achieved in that a kind of drum type braking device, comprises brake block static in brake drum and the brake drum along with vehicle wheel rotation, and the rubbing surface of brake drum arranges at least one annular ditch groove, and the rubbing surface of brake block is the face matching with annular ditch groove.
Described drum type braking device, described annular ditch groove is ring-type curved surface groove, the rubbing surface of brake block is the face ring-type curved surface convex tendon matching with ring-type curved surface groove.
Described drum type braking device, described ring-type curved surface groove is ring-type arc groove, the rubbing surface of brake block is the ring-type circular arc convex tendon face matching with ring-type arc groove.
Described drum type braking device, described annular ditch groove is ring-type V-shape groove, the rubbing surface of brake block is the ring-type V-shape convex tendon face matching with ring-type V-shape groove.
Described drum type braking device, the numerical value of described V-shape convex tendon mean breadth is greater than the numerical value of V-shape groove mean breadth, and V-shape convex tendon top is circular arc.
Described drum type braking device, described annular ditch groove is ring-type trapezoidal groove, the rubbing surface of brake block is the trapezoidal convex tendon face of ring-type matching with ring-type trapezoidal groove.
Described drum type braking device, the numerical value of the mean breadth of described trapezoidal convex tendon is greater than the numerical value of trapezoidal groove mean breadth.
Described drum type braking device, described annular ditch groove quantity is one of 2,3,4,5,6.
Described drum type braking device, described annular ditch groove is arranged on the rubbing surface of brake block, and described ring-type convex tendon is arranged on the rubbing surface of brake drum.
Brake lining of the present invention is established groove, has increased friction area, does not need large stampede power or oil pressure.Do not need the brake drum that uses diameter larger, just can improve the strength of brake yet.Coordinate ring-type V-shape convex tendon for ring-type V-shape groove, in the time that ring-type V-shape groove is adjacent to completely with ring-type V-shape convex tendon (the two angle is identical), because the numerical value of V-shape convex tendon mean breadth is less times greater than the numerical value of V-shape groove mean breadth, V-shape convex tendon top is circular arc, V-shape convex tendon moves forward a little again, groove just produces huge clamping force, can effective brake, ring-type trapezoidal groove coordinates the situation of the trapezoidal convex tendon of ring-type the same with the situation of ring-type V-shape groove cooperation ring-type V-shape convex tendon.
