Specific implementation mode
In order to clarify the technical characteristics of the invention, below by a specific implementation mode, and in conjunction with attached drawing, to this
Scheme
It is illustrated.
The automatic continuous adjustable drum brake in a kind of gap, by fixed plate 1, right friction plate 2, return spring group 3, lower system
Dynamic cylinder assembly 4, left friction plate 5, upper checking cylinder assembly 6 composition, fixed plate 1 are fixedly mounted in vehicle bridge, upper checking cylinder assembly 6,
Lower checking cylinder assembly 4 is respectively and fixedly installed in fixed plate 1, and the upper fastener of right friction plate 2 is placed on checking cylinder assembly 6
Right braking push away in cylinder notch, the right braking that the lower fastener of right friction plate 2 is placed on lower checking cylinder assembly 4 pushes away cylinder notch
In, same principle, the upper fastener of left friction plate 5 is placed in the left braking on checking cylinder assembly 6 and pushes away in cylinder notch, left friction
The left braking that 5 times fasteners of piece are placed on lower checking cylinder assembly 4 pushes away in cylinder notch, and the both ends of return spring group 3 are separately connected
In left friction plate 5 and right friction plate 2, to brake return, the brake piping interface 103 on checking cylinder assembly and brake pipe
Road connects, and left and right is respectively equipped with a set of braking and pushes away cylinder 104 on checking cylinder assembly, and braking pushes away 104 upper limit guide rod 109 of cylinder and passes through
Pilot hole on shell 102 is dynamic to prevent rotation stop；
The lower checking cylinder assembly 4, upper 6 structure of checking cylinder assembly are identical, left and right thereon to carry fluid pressure type limit and adjust
Engagement positions, for continuously adjusting the gap between brake disc and friction plate, fluid pressure type limits adjusting apparatus by limit knock-pin
105, stop nut 106, adjusting nut 107 form, and stop nut 106 is fixedly mounted on the top of limit knock-pin 105, adjustment
Nut 107 and limit knock-pin 105 are threadedly coupled, and braking pushes away the lifting lug on cylinder 104 and is mounted on stop nut 106, adjusting nut
Between 107, gap is limited to realize by adjusting the position of adjusting nut 107；
Hand-operated valve 108 is installed on housing 102, and accumulator 101 has fluid, accumulator 101 and limit knock-pin 105 it
Between be connected with check valve 110, form unidirectional oil circuit, hand-operated valve 108 is in parallel with 110 oil circuit of check valve, and hand-operated valve 108 is normally closed.
When braking, the brake pressure in vehicle brake conduit pushes the left and right braking on upper and lower checking cylinder assembly to push away cylinder
Shifting outside 104 pushes away cylinder 104 and friction plate is pushed to generate frictional force with brake disc, and vehicle is braked, and when pushing away shifting outside cylinder 104, can be driven
It limits and is moved outside knock-pin 105, the outer shifting of limit knock-pin 105 can cause oil pocket pressure reduction, and then check valve 110 is pushed to beat
It opens, the fluid in accumulator 101 enters cavity, and when end of braking, return spring group 3 can drive right friction plate 2, left friction plate 5
Return, under the action of check valve 110, knock-pin 105 will not return, adjusting nut 107, which can stop, pushes away 104 return of cylinder, due to
The presence in the adjustment gap between stop nut 106, adjusting nut 107, ensures the brake clearance between friction plate and brake disc
In values, and then improve brake efficiency.
When more renewal of facing renewal, hand-operated valve 108 is opened, fluid returns to accumulator 101, re-starts gap adjustment.
Although the preferred embodiment of the present invention is described in connection with figures above, the invention is not limited in above-mentioned
Specific implementation mode, the above mentioned embodiment is only schematical, is not restrictive, the common skill of this field
