Description
Technical field
the utility model relates to a kind of brake disc.
Background technique
along with reaching its maturity with people to the requirements at the higher level of Green Travel of bike tech development, bicycles increases is manyly in daily life, and thus, improving bicycle aspect of performance, researcher has dropped into more energy, particularly about cycle brake.The bicycle brake system of current use mainly contains disc type and drum-type two type, disk type braker due to its be swift in response, stability and the advantage such as thermal diffusivity is good and be widely used, brake disc of the prior art is formed in one, in use, because outer disk is subject to friction greatly, therefore to wear and tear severity, must by brake disc integral replacing when changing.
Summary of the invention
technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of brake disk for bicycle.
for solving above technical problem, the utility model takes following technological scheme:
a kind of disc type brake dish, described brake disc comprises: inner disc, be arranged on the outer disk of described inner disc periphery, described outer disk comprises braking part and is positioned at the first joint inside described braking part, described inner disc comprises for described brake disc being installed to the assembly department on bicycle, the second joint outside described assembly department, being connected to transition part between described assembly department and the second described joint, the first described joint and the second described joint in mating connection, described outer disk parallels setting with described assembly department.The first described joint comprises multiple the first link arm extended internally, the first described link arm is provided with the first mounting hole, the second described joint comprises multiple outward extending second link arm, the second described link arm is provided with the second mounting hole, and the first described mounting hole and the second described mounting hole coincide and are bolted.The first described link arm and the diametric(al) of outer disk have an inclination angle, described the second link arm described in multiple first link arms stretches out along the outer peripheral tangent direction of transition part, and described multiple first link arm and multiple second link arm are to inclined.
preferably, described transition part tilts from the second joint gradually to described assembly department.
preferably, the transition part depression that described assembly department is relatively described, described transition part and described assembly department perpendicular.
preferably, described outer disk is provided with 8 the first link arms, and described inner disc is provided with 8 the second link arms.
preferably, the braking part of described outer disk is provided with multiple through hole for increasing braking part frictional force.
preferably, the assembly department of described inner disc has the multiple attachment holes be intervally arranged along its circumference, and described brake disc is arranged on wheel by described attachment hole.
due to the enforcement of above technological scheme, the utility model compared with prior art tool has the following advantages:
inner disc of the present utility model and outer disk are not one-body molded, but are bolted to connection, and when such outer disk is damaged, can only outer disk be changed.
Accompanying drawing explanation
below in conjunction with accompanying drawing and concrete mode of execution, the utility model is described in more detail.
fig. 1 is the structural representation of a kind of brake disk for bicycle described in the utility model;
fig. 2 is the side-looking structural representation of a kind of brake disk for bicycle described in the utility model;
fig. 3 is the side-looking structural representation of another kind of brake disk for bicycle described in the utility model;
wherein: 1, outer disk; 11, braking part; 12, the first link arm; 2, inner disc; 21, assembly department; 22, transition part; 23, the second link arm; 3, bolt.
Embodiment
a kind of brake disk for bicycle as shown in Fig. 1 ~ 3, described brake disc comprises: inner disc 2, be arranged on the outer disk 1 of described inner disc 2 periphery, the first joint that described outer disk 1 comprises braking part 11 and is positioned at inside described braking part 11, described inner disc 2 comprises the assembly department 21 for being installed to by described brake disc on bicycle, be positioned at the second joint outside described assembly department 21, be connected to the transition part 22 between described assembly department 21 and the second described joint, the first described joint and the second described joint in mating connection, described outer disk 1 parallels setting with described assembly department 21.The first described joint comprises multiple the first link arm 12 extended internally, the first described link arm 12 is provided with the first mounting hole, the second described joint comprises multiple outward extending second link arm 23, the second described link arm 23 is provided with the second mounting hole, and the first described mounting hole is coincided with the second described mounting hole and is connected by bolt 3.The first described link arm 12 has an inclination angle with the diametric(al) of outer disk 1, described the second link arm 23 described in multiple first link arms 12 stretches out along the outer peripheral tangent direction of transition part 22, and described multiple first link arms 12 and multiple second link arm 23 are to inclined.Described transition part 22 tilts from the second joint gradually to described assembly department 21.In another embodiment, the relatively described transition part 22 of described assembly department 21 caves in, and described transition part 22 is perpendicular with described assembly department 21.Preferably, described outer disk 1 is provided with 8 the first link arms 12, and described inner disc 2 is provided with 8 the second link arms 23.The braking part 11 of described outer disk 1 is provided with multiple through hole for increasing braking part 11 frictional force.The assembly department 21 of described inner disc 2 has the multiple attachment holes be intervally arranged along its circumference, and described brake disc is arranged on wheel by described attachment hole.
above the utility model is described in detail, but the utility model is not limited to the above embodiments.All equivalences done according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
