For solving above-mentioned technical problem, the technical solution of the utility model is: Brake for vehicle, including back-plate and system
Dynamic drum, described back-plate is symmetrically installed with two brake-shoes, and the fixing end of brake-shoe described in two is respectively by pivot pin and institute
State back-plate to be rotatably assorted, between the movable end of brake-shoe described in two, be provided with brake;Brake-shoe described in two it
Between be additionally provided with return spring and lash adjusting device;The inner circumferential side of described brake drum is circumferentially arranged drag ring, described in rub
Wiping and some louvre is distributed on ring, the inner peripheral surface of described drag ring constitutes friction pair braking with the outer surface of described brake-shoe
Face;
Described lash adjusting device includes that adjusting lever, one end of described adjusting lever are hinged with one of them brake-shoe, institute
The other end stating adjusting lever abuts against with another brake-shoe;The upper surface of described adjusting lever is provided with ratchet, described back-plate
On be provided with the ratchet matched with described ratchet;The lower surface of described adjusting lever is provided with tractive spring.
As preferred technical scheme, described brake includes being installed at the bottom of described braking by cam axle
Driving cam on plate, the movable end of brake-shoe described in two is fixedly installed the driven rolling matched with described driving cam respectively
Wheel.
As preferred technical scheme, the outer surface of described brake-shoe is provided with brake(-holder) block;The inner circumferential of described drag ring
Face constitutes friction pair braking surface with the outer surface of described brake(-holder) block.
As preferred technical scheme, described drag ring includes the friction plate of more than three, two adjacent friction plates it
Between be provided with gap.
Owing to have employed technique scheme, this utility model has the advantages that
(1) inner circumferential side of described brake drum is circumferentially arranged drag ring so that drag ring be all surrounded brake-shoe and not
There is absent region, owing to drag ring area increases so that during braking, the abrasion of drag ring reduces, and not only extends drag ring
Service life, and add frictional damping effect;Simultaneously because drag ring material itself has certain thermal insulation, friction system
The heat produced time dynamic is taken away by louvre and is passed to brake drum hardly, thus avoids the thermal deformation of brake drum, carries
The high serviceability of brake.
(2) realizing the gap of brake by ratchet and ratchet automatically to adjust, decoration structure features simple design, parts are few, safeguard
It is convenient to change.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.In the following detailed description, only by saying
Bright mode describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art is permissible
Recognize, in the case of without departing from spirit and scope of the present utility model, can be by various different modes to described
Embodiment is modified.Therefore, accompanying drawing and description are inherently protection that is the most illustrative rather than that be used for limiting claim
Scope.
As depicted in figs. 1 and 2, Brake for vehicle, including back-plate 1 and brake drum 2, symmetrical on described back-plate 1
Being provided with two brake-shoes 3, the fixing end of brake-shoe 3 described in two is rotatably assorted with described back-plate 1 by pivot pin 4 respectively,
It is provided with brake between the movable end of brake-shoe 3 described in two;Between the corresponding fixing end of brake-shoe 3 described in two and
A return spring 5 it is respectively arranged with between respective activity end;It is additionally provided with lash adjusting device between brake-shoe 3 described in two;
The inner circumferential side of described brake drum 2 is circumferentially arranged drag ring 6, and some louvre 7 is distributed on described drag ring 6, described in rub
The outer surface of the inner peripheral surface and described brake-shoe 3 of wiping ring 6 constitutes friction pair braking surface.So, drag ring be all surrounded system
Move hoof and there is not absent region, owing to drag ring area increases so that during braking, the abrasion of drag ring reduces, and not only extends
The service life of drag ring, and add frictional damping effect;Simultaneously because drag ring material itself has certain heat insulation
Property, the heat produced during frictional damping is taken away by louvre 7 and is passed to brake drum 2 hardly, thus avoids brake drum 2
Thermal deformation, improve the serviceability of brake.Described drag ring 6 is preferably made up of the friction plate 12 of more than three, this reality
Execute in example as a example by 4, and between two adjacent friction plates 12, be provided with gap 13, be so more convenient for changing, and permissible
Change one by one, to reduce maintenance cost.
In the present embodiment, described brake includes being rotated by camshaft 8 being installed on described back-plate 1
Driving cam 9, the movable end of brake-shoe 3 described in two is fixedly installed the return idler matched with described driving cam 9 respectively
10.It is of course also possible to use the driving means of other forms, such as wheel cylinder etc..
In the present embodiment, described lash adjusting device includes adjusting lever 14, one end of described adjusting lever 14 and one of them
Brake-shoe 3 is hinged, and the other end of described adjusting lever 14 abuts against with another brake-shoe 3;The upper surface of described adjusting lever 14 sets
It is equipped with ratchet 15, described back-plate 1 is provided with the ratchet 16 matched with described ratchet 15;The lower end of described adjusting lever 14
Face is provided with tractive spring 17.When drag ring abrasion is less, the anglec of rotation of adjusting lever 14 can be the least, ratchet 16 and ratchet 15
Site of engagement does not changes, when drag ring abrasion is bigger, and adjusting lever 14 anglec of rotation meeting under tractive spring 17 traction action
Becoming big, now, ratchet 16 again engages with ratchet 15 and makes two brake-shoe 3 opened with certain angle, thus realizes automatically adjusting
The gap of joint brake.
In order to reduce the abrasion of brake-shoe, improve its service life, the outer surface of described brake-shoe 3 is preferably provided braking
Sheet 11;Now, the inner peripheral surface of described drag ring 6 constitutes friction pair braking surface with the outer surface of described brake(-holder) block 11, is prevented effectively from
The abrasion of brake-shoe and the thermal deformation of brake drum, improve the service life of brake-shoe and brake drum.
The foregoing is only the schematic detailed description of the invention of this utility model, be not limited to model of the present utility model
Enclose.Any those skilled in the art, equivalent done on the premise of without departing from design of the present utility model and principle becomes
Change and amendment, the scope of this utility model protection all should be belonged to.
