Abstract
A kind of drum type braking device, including brake block static in brake rim and along with the brake rim of vehicle wheel rotation, the rubbing surface of brake rim arranges at least one annular ditch groove, and the rubbing surface of brake block is the face matched with annular ditch groove.The brake lining of the present invention sets groove, increases friction area, is not required to big stampede power or oil pressure.Also it is not required to use the brake rim being relatively large in diameter, just can improve the strength of brake.For ring-type V-shape ditch slot fit ring-type V-shape convex tendon, when ring-type V-shape groove is adjacent to completely with ring-type V-shape convex tendon (the two angle is identical), owing to 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 is displaced slightly forwards again, groove just produces huge clamping force, can effective brake, ring-type trapezoidal groove coordinate ring-type trapezoidal convex tendon situation as the situation of ring-type V-shape ditch slot fit ring-type V-shape convex tendon.
Description
Technical field
The present invention is to be mainly used in brake and drive system for vehicle with tow it can also be used to the brake system of other rotatable parts, particularly as being, has the ironcasting being shaped like tambourine, referred to as a brake rim, and it is fixed and synchronized rotation with tire；Using oil pressure to promote brake block (Brake Shoes) contact brake rim inner edge during brake, the friction produced by contact suppresses the rotation of tire to reach a kind of drum type braking device of the purpose of brake.
Background technology
Briefly, drum brakes be exactly utilize brake rim in static brake block, go to rub along with the brake rim of vehicle wheel rotation, turn a wheel the brake gear that speed reduces producing frictional force.When stepping on brake pedal, the force of foot can make the piston in master cylinder brake fluid be pushed forward and produce pressure in oil circuit.Pressure is sent to the wheel cylinder piston of each wheel via brake fluid, and the piston of wheel cylinder promotes brake block outside again, makes brake block rub with the inner face of brake rim, and produces enough friction and remove the rotating speed of reduction wheel, to reach the purpose braked.
Rousing the good effect of certainly stopping of stopping, owing to brake lining off-chip is opened, wheel rotates brake rim one angle of distortion (surely not greatly to allowing you be easy to it appear that come) the brake lining off-chip being inconjunction with outerTension force(brake control power) is the biggest, then situation is the most obvious, and therefore, general oversize vehicle still uses drum to stop, and in addition to cost is relatively low, the drum of large car and compact car is stopped, and difference may be venerated large-scale gas production dynamic auxiliary, and compact car is adopted vacuum aided and helped to brake.But, the overload of Chinese large-sized car is universal, original drum is stopped and can not be adapted to overload condition for a long time, and the design of vehicle has overall relevance, the biggest for rousing the space stayed of stopping, if needing to increase space will change many designs, can not blindly strengthen so the drum of large car is stopped, how to increase, in the space that existing drum is stopped, the brake force that drum is stopped, be the problem needing to solve.
Summary of the invention
The problem increasing the brake force that drum is stopped in order to solve large car in the space that existing drum is stopped, the present invention provides a kind of drum type braking device.
The present invention is achieved in that a kind of drum type braking device, and including brake block static in brake rim and along with the brake rim of vehicle wheel rotation, the rubbing surface of brake rim arranges at least one annular ditch groove, and the rubbing surface of brake block is the face matched with annular ditch groove.
Described drum type braking device, described annular ditch groove is ring-type curved surface groove, the face ring-type curved surface convex tendon that the rubbing surface of brake block is with ring-type curved surface groove matches.
Described drum type braking device, described ring-type curved surface groove is ring-type arc groove, and the rubbing surface of brake block is the ring-type circular arc convex tendon face matched with ring-type arc groove.
Described drum type braking device, described annular ditch groove is ring-type V-shape groove, and the rubbing surface of brake block is the ring-type V-shape convex tendon face matched with ring-type V-shape groove.
Described drum type braking device, the numerical value of described V-shape convex tendon mean breadth is more 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, and the rubbing surface of brake block is the ring-type trapezoidal convex tendon face matched with ring-type trapezoidal groove.
Described drum type braking device, the numerical value of the mean breadth of described trapezoidal convex tendon is more than the numerical value of trapezoidal groove mean breadth.
Described drum type braking device, described annular ditch groove quantity is 2,3,4,5, one of 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 rim.
The brake lining of the present invention sets groove, increases friction area, is not required to big stampede power or oil pressure.Also it is not required to use the brake rim being relatively large in diameter, just can improve the strength of brake.For ring-type V-shape ditch slot fit ring-type V-shape convex tendon, when ring-type V-shape groove is adjacent to completely with ring-type V-shape convex tendon (the two angle is identical), owing to 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 is displaced slightly forwards again, groove just produces huge clamping force, can effective brake, ring-type trapezoidal groove coordinate ring-type trapezoidal convex tendon situation as the situation of ring-type V-shape ditch slot fit ring-type V-shape convex tendon.
