Description
Technical field
The present invention relates to break, be specially the blank compensation apparatus between brake strip and Brake drum (dish) in break.
Background technique
In break running, because of the wearing and tearing of rubbing surface and the Brake drum wheel face (or brake disc card) of brake strip, to cause that the friction catch gap between rubbing surface and the Brake drum wheel face (or brake disc card) of brake strip increases, cause the rubbing surface of the friction plate Brake drum wheel face (or card of brake disc) of can not effectively fitting, cause braking force to diminish or disappear.For ensureing braking effect, need the friction catch gap increasing because of wearing and tearing be adjusted or be compensated,, by friction catch blank compensation apparatus, the friction catch gap of increase is adjusted to and can guarantees the gap of break in normal brake application work.
Existing friction catch blank compensation apparatus is referring to Fig. 1.Comprise guide sleeve 1 and rotating shaft 2, guide sleeve 1 is connected with a side brake arm 3 of break by hinge, outer section of rotating shaft 2 is positioned at guide sleeve 1, and supported by the bearing components 1a on guide sleeve 1, the outside axle head of rotating shaft 2 connects manual pulley 4, rotating shaft 2 middle parts are provided with the driving mechanism 5 that drives this rotating shaft to rotate, there is thread section 2a rotating shaft 2 the inners, the screw thread of axle sleeve 6 one end and described thread section 2a are connected, the other end of axle sleeve 6 connects one end of adjusting axle 7, the other end of adjusting axle 7 is connected with lever 8 the inners in break by hinge, lever 8(also claims A-frame arm) lever arm and opposite side brake arm 9 stud connections of break, the push rod 10a stud connection of lever 8 outer ends and pusher 10.The operating process of this friction catch blank compensation apparatus is, when the rubbing surface of friction plate and the wheel face of Brake drum 11 are worn while causing that friction catch excesssive gap need to be adjusted or compensate, open motor 5a, drive driving mechanism 5 forward operations, drive rotating shaft 2 to rotate, the screw-thread fit effect of thread section 2a and axle sleeve 6 by rotating shaft 2 the inners, axle sleeve 6 is along thread section 2a to left dislocation, thereby make two brake arms 3,9 respectively around A1, the indentation to the inside of A2 fulcrum, first make fit the respectively wheel face of Brake drum 11 of the rubbing surface of both sides friction plate 3a, 9a; Then antiport motor 5a, driving mechanism 5 inverted runnings, drive rotating shaft 2 to rotate backward, and axle sleeve 6 is along thread section 2a displacement to the right, two brake arms 3,9 are with respectively movable friction plate 3a, 9a to open to both sides, and the friction catch gap increasing is adjusted or compensated.The deficiency that this friction blank compensation apparatus exists is: because this friction catch blank compensation apparatus adopts motor 5a and driving mechanism 5, drive rotating shaft 2 to rotate the adjustment or the compensation that realize friction catch gap, the simultaneously Brake drum locking in the time that the axle head of rotating shaft 2 arranges manual pulley 4 and meets break and do not move, not only structure is loaded down with trivial details and increase cost, and by controlling motor revolution or moving to adjust friction catch gap with limit switch control motor, due to the slack time of operation inertia and the limit switch transmission of signal of motor, affect adjustment or the compensation precision in friction catch gap.
Summary of the invention
The object of the invention is to propose a kind of friction catch blank compensation apparatus, the present invention realizes friction catch gap and adjusts or when compensation meeting, not only simple in structure, reduce manufacture cost, and can improve that friction catch gap is adjusted or the control accuracy of compensation.
