It saves gear to be sequentially connected with adjusting screw rod, adjusting screw rod both ends are driven with 21 upper end of the first disc and 31 upper end of the second disc respectively
Connection.The effect of brake-shoe adjustment mechanism 50 is to adjust the spacing of the first disc 21 and the second disc 31, namely adjusting first
The spacing of brake-shoe 20 and the second brake-shoe 30.
The structure of first brake-shoe hold-down mechanism 60 and the second brake-shoe hold-down mechanism 70 can be：First brake-shoe compresses
Mechanism 60 includes the first spacer pin, the first holddown spring and the first locking cap；First spacer pin is by the first disc 21 in bottom plate
It is positioned in mechanism, the first holddown spring is sleeved on the first spacer pin, and top is locked by the first locking cap, and bottom resilient compresses institute
State the first disc 21；Second brake-shoe hold-down mechanism 70 includes the second spacer pin, the second holddown spring and the second locking cap；The
Two spacer pins position the second disc 31 on base plate mechanism, and the second holddown spring is sleeved on the second spacer pin, and top is by the
Two locking caps are locked, and bottom resilient compresses second disc 31.
The structure of brake-shoe spreading mechanism 80 can be：Including torque arm strut component and returning spring；The reply bullet
Spring both ends are resiliently mounted between 31 lower end of 21 lower end of the first disc and the second disc, the torque arm strut component both ends respectively with
First disc, 21 lower end is connected with 31 lower end of the second disc.The effect of brake-shoe spreading mechanism 80 is to make the first disc 21 and second
Disc 31 can be replied in non-brake state, even if also the first brake-shoe 20 and the second brake-shoe 30 energy in non-brake state
It is enough to reply.
As shown in figure 9, due to position-limit mechanism in drum brake in the disk of the present embodiment, in gravity and impact of jolting
Gap between effect the first brake-shoe 20 and the second brake-shoe 30 and brake drum 40 of power is still very uniform, to effectively prevent
The problem of dawdling that brake-shoe tenesmus is brought, greatly improved the service life of drum brake and parking performance in disk, disappears simultaneously
In addition to abrasion and abnormal sound problem, additional oil consumption and power loss problem caused by dawdling are avoided.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
