Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment and join
According to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid this is unnecessarily obscured
The concept of invention.
Specific embodiment: in conjunction with shown in Fig. 1-5, including brake drum 1；The relatively narrow one end of 1 upper diameter of brake drum
For mounting surface 101；The 101 top border of mounting surface is evenly arranged with mounting hole 102；It is braking surface inside the brake drum 1
103；1 side of brake drum is provided with brake apparatus 2；The brake apparatus 2 is internally provided with driving device 3；The braking
It is connected by screw bolts between device 2 and the driving device 3；The brake apparatus 2 includes support plate 201, support column 202, branch
Pushing out ring 203 and brake-shoe 204；It is clamped between the support plate 201 and the support ring 203 using latching support column 202；It is described
201 top middle position of support plate is provided with spline 205；The 203 outer surface border of support ring is evenly arranged with multiple solid
Determine block 206；It is connected by screw bolts between multiple fixed blocks 206 and the support ring 203；The setting of brake-shoe 204 exists
206 middle position of fixed block is simultaneously connect with the fixed block 206 by 207 shaft of torsionspring；The driving device 3 is wrapped
Include drive shaft 301, spring leaf 302 and expander 4；Described 301 one end of drive shaft is provided with external splines 303；The drive shaft 301
Lower end middle position is provided with the spring leaf 302；301 two sides of drive shaft are symmetrically arranged with the expander 4；The expansion
Prop 4 includes fixed frame 401, L shape curved boom 402, reset frame 403 and expanding plate 404；401 both ends of fixed frame are symmetrical arranged
There is the L shape curved boom 402；402 both ends of L shape curved boom use between the drive shaft 301 and the reset frame 403 respectively
Clamping；402 middle position of L shape curved boom is connect with the fixed frame 401 using shaft；The expanding plate 404 and reset frame
It is connected by screw bolts between 403.
In use, step 1, as shown in Figure 1, when user carries out the selection of automobile brake mode, since load-carrying is larger
Automobile usually select drum brakes, be but the drum brakes because the absolute brake power of drum brakes will be due to disk type brake
Brake be highly prone to the drive of brake drum 1 in braking so that drum brakes will appear the dead situation of automatic brake, from
And make the abrasion of brake drum 1 and brake larger, easily there is the case where brake fade, for this purpose, this can be used in user
A kind of heavy-duty car of money combined type ANTI LOCK drum, to solve the presence of above situation；
Step 2, as shown in Figure 2-5, user are installed brake drum 1 by the mounting hole 102 on 1 mounting surface of brake drum, 101 top
On vehicle bridge, and brake apparatus 2 and driving device 3 are mounted on 1 inside of brake drum close to vehicle bridge side, when user makes
When dynamic, user steps on brake pedal this moment, and brake pedal then can utilize hydraulic oil driver 3 by oil pressure pump
The drive shaft 301 on top, due to using external splines 303 to be slidably connected with spline 205 between drive shaft 301 and support plate 201
Mode, therefore drive shaft 301 is merely able in axial direction be moved, and when drive shaft 301 is moved to 1 direction of brake drum, drives
Moving axis 301 starts to drive the L shape curved boom 402 of upper part clamping, and L shape curved boom 402 can then be turned around 401 one end of fixed frame
Dynamic, so that reset frame 403 drives expanding plate 404 to expand outwardly, expanding plate 404 will be with brake-shoe 204 after starting expansion
Inner surface contact, so that brake-shoe 204 be driven to circumferentially rotate at the center of fixed block 206, support ring 203 this moment
The braking surface 103 that the multiple groups brake-shoe 204 of top setting will start from brake drum 1 comes into contact with, and then generates braking effect,
To reduce speed, it is arranged in parallel due to being used between brake-shoe 204 and braking surface 103, and unconventional rectilinear arrangement, therefore
It is braked when the rotation of brake drum 1, brake drum 1 can not generate the trend that circumferentially rotates to brake-shoe 204, therefore brake-shoe
204 the case where being not in braking with locked wheels drum 1；
Step 3, as shown in Figure 2-5, when user loosens the brake, oil pressure pump starts to recycle hydraulic oil this moment, and drives
Axis 301 also start drive brake apparatus 2 inside component resetted, this moment expanding plate 404 no longer with the interior table of brake-shoe 204
Face is in contact, and brake-shoe 204 can then be realized under the drive of torsionspring 207 and be automatically reset, thus be detached from brake drum 1 it
Between braking, and use brake apparatus 2 and the combined arrangement of driving device 3, expand 1 inner space of brake drum, favorably
Good heat dissipation is carried out in brake drum 1, prevents the overheat of brake drum 1 to the case where brake fade occur.
Control mode of the invention is automatically controlled by controller, the skill that the control circuit of controller passes through this field
Art personnel's simple programming can be realized, and belong to the common knowledge of this field, and the present invention is mainly used to protect mechanical setting, institute
Control mode and circuit connection are not explained with the present invention.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention
Covering the whole variations fallen into attached claim scope and boundary or this range and the equivalent form on boundary and is repairing
Change example.
