Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As in Figure 3-5, the base plate of a kind of drum brake that the utility model embodiment provides, comprise plate body 21, plate body 21 is provided with multiple brake shoe and slips platform 211, brake shoe slips on platform 211 and is connected with at least one sliding part 22, sliding part 22 is provided with sliding plane, and sliding part 22 is working of plastics.
Concrete, plate body 21 is slidably connected by the sliding sliding Planar realization of part 22 and the brake shoe 23 of drum brake, plate body 21 is sheet metal part, plate body 21 is provided with multiple brake shoe and slips platform 211, as six, six brake shoes slip in platform 211 circumference and are evenly arranged, brake shoe slips platform 211 for affixed sliding part 22, it provides a fixing part with fixing sliding part 22, fixing part can be hole or groove, slip part 22 with clamping, fixing part also can other structure, and it can fix sliding part 22.Sliding part 22 is provided with a sliding plane, for the brake shoe 23 that is slidably connected, sliding part 22 is structurally except having sliding plane, and can meeting of other is fixed to brake shoe and slips condition on platform 211.Sliding part 22 can be one, also can be multiple, can smooth and easy effective to slip with brake shoe 23 be as the criterion.In the working procedure of drum brake, brake shoe 23 is back and forth at the sliding sliding on planes of sliding part 22, and sliding part 22 is working of plastics, and so both slips are the relative sliding of metal flat and plastic surface, and noise is less.
The base plate of the drum brake that the present embodiment provides, plate body 21 is connected to the sliding part 22 of a plastic material, and plate body 21 is slipped by the sliding Planar realization on this sliding part 22 and brake shoe 23.So, the relative sliding slipped for working of plastics and metalwork of plate body 21 and brake shoe 23, the slip of metalwork and metalwork compared to existing technology, the decibel value of its noise significantly reduces.
In the present embodiment, preferably, brake shoe slips on platform 211 and has a plane, and sliding part 22 is dull and stereotyped, and flat board is fixed in plane.Preferred, flat board is bonded in plane.Flat panel production is convenient, and precision is easy to control, during installation also more for convenience.
In the present embodiment, further, sliding plane is provided with lubricating layer.As smeared lubricating grease in sliding plane, the sliding part 22 of reduction and brake shoe slip the friction factor of platform 211, the working life of both prolongations.
In the present embodiment, preferably, one end of sliding part 22 is provided with sliding plane, and the other end of sliding part 22 is provided with inserted part 221, and brake shoe slips on platform 211 and offers through hole, and inserted part 221 is stuck in through hole.Preferred, inserted part 221 is cone-shape barbs, cone-shape barbs offers axial deformation gap.The benefit of clamping is installation and removal all more for convenience, and, after sliding part 22 weares and teares, sliding part 22 can also be changed, thus extend the working life of base plate.This compared to existing technology in brake shoe 23 directly slip advantageously with base plate.
In the present embodiment, preferably, the edge sliding part 22 being positioned at sliding plane is arc-shaped transition.Arc-shaped transition makes brake shoe 23 more smooth and easy with slipping of sliding part 22, reduces the probability of sliding part 22 scratching brake shoe 23.
The present embodiment also provides a kind of drum brake, and comprise base plate and be slidably connected to the brake shoe 23 on base plate, base plate is above-mentioned base plate, and base plate is by being slidably connected with sliding plane and brake shoe 23.
Because above-mentioned base plate has above-mentioned technique effect, the drum brake comprising this base plate also should have corresponding technique effect.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
