The part of drum brakes system, processing is relatively simple with composition, with more cheap manufacturing cost, is more applied small
The trailing wheel of type car, but its rate of wear is higher, particularly brake block, when abrasion to a certain extent when, it is necessary to the brake for more renewing
Piece.
The core component of drum brakes system is brake rim and brake block, and the China of Application No. 201410761818.5 is specially
Profit discloses a kind of brake rim, is socketed in the outer wall of brake rim and coolant is filled with metal cavitg, the metal cavitg, described
Conducting strip is additionally provided with metal cavitg, sets jagged in the side of the metal cavitg, the conducting strip is provided with heat conduction
Branch piece, with the purpose for reaching the cooling of drum brakes system, preventing explosion；
And existing drum-type brake pad is usually the arc brake piece of uniform thickness, the extrados laminating brake rim of brake block, muscle
Plate fitted in the presence of brake pump wheel cylinder brake block intrados frictional force produce braking effect, in the middle part of brake block
Thickness is identical with the thickness on both sides, and the extrados radian of brake block is identical with intrados radian, and in gusset needs and brake block
Cambered surface fit, be designed as have and brake block intrados identical radian；But, existing drum brakes system is actually used one
After the section time, the abrasion for finding brake block is not uniform, and often the degree of wear in the middle part of brake block is larger, is occurred middle
It is thin, the thick situation in both sides, and when being worn and torn to a certain extent in the middle part of brake block, it is necessary to brake block is changed, in case gusset touches brake
Drum, causes drum brakes system injury；And the brake block both sides under changing are still thicker, fully worn and torn, cause to waste.
The content of the invention
The technical problems to be solved by the invention are：A kind of drum brakes system is provided, brake block intrados radian is entered
Row is improved, and correspondingly improves the extrados radian of gusset, and brake block is unable to uniform wear in solving existing drum brakes system
And wasting problem.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of drum brakes system, including longitudinal direction
Section is brake rim, the brake block installed in brake rim inner circle and the gusset with brake block frictional connection of annulus；
The longitudinal cross-section of the brake block is arc, and the extrados of the brake block is fitted with the inner headed face of brake rim；
The link of boards is radian and brake block inner arc with the joint face of brake block in brake pump wheel cylinder, the gusset
Face identical arcwall face；
The outer arc length of the brake block longitudinal cross-section is long with inner arc equal, and the outer arc radius of the brake block longitudinal cross-section are
The 90-95% of the interior arc radius of the brake block longitudinal cross-section.
The beneficial effects of the present invention are：The present invention relates to a kind of drum brakes system, the shape to brake block changes
Enter, make the radian of the intrados of brake block more than the radian of extrados, make the middle part of brake block slightly thicker than both sides, correspondingly improve
Gusset and the joint face of brake block, are designed as the intrados radian identical arcwall face of radian and brake block, when vehicle is braked,
Brake pump wheel cylinder jack-up gusset, makes gusset laminating brake block intrados, is rubbed, and above-mentioned drum brakes system is using one
After the section time, brake block uniform wear, the thickness approximately equal in the middle part of brake block makes brake block obtain fully in the thickness on both sides
Abrasion, improve the utilization rate of brake block, so as to increase the service life of brake block, save the use of drum brakes system into
This.
