Embodiment
As shown in Fig. 4 to Fig. 8, the automotive brake assembly that the utility model embodiment provides, it comprises braking bottom board 61, shoe shaft 51, two brake shoes be oppositely arranged 21.Wherein, shoe shaft 51 comprises installation shaft 52, is arranged on first axle 53 and second axle 54 at installation shaft 52 two ends, the fixed hole Spielpassung of installation shaft 52 and braking bottom board 61; The diameter of installation shaft 52 is greater than the diameter of the first axle 53 and the diameter of the second axle 54; The both sides of the internal surface of brake shoe 21 are arranged with the first braking tendons of beef, mutton or pork 31 and the second braking tendons of beef, mutton or pork 41 in parallel; The first end of the first braking tendons of beef, mutton or pork 31 is provided with the first arc opening for matching with the outer surface of the first axle 53, and the first end of the second braking tendons of beef, mutton or pork 41 is provided with the second arc opening for matching with the outer surface of the second axle 54; The first end of the first braking tendons of beef, mutton or pork 31 is provided with the first keep-spring mounting hole 32.Be understandable that, the first braking tendons of beef, mutton or pork 31 are all identical with the bearing of trend of brake shoe 21 with the bearing of trend of the second braking tendons of beef, mutton or pork 41; Two brake shoes be oppositely arranged 21 have identical structure, first arc opening of two brake shoes 21 and the second arc opening, under the effect of the keep-spring 63 that the first keep-spring mounting hole 32 is installed, be clamped on shoe shaft 51, realize the connection with braking bottom board 61 by shoe shaft 51; Simultaneously, diameter due to installation shaft 52 is greater than the diameter of the first axle 53, the diameter of installation shaft 52 is also greater than the diameter of the second axle 54, thus making installation shaft 52 and the first axle 53, forming station terrace between installation shaft 52 and the second axle 54, the laminating of braking the tendons of beef, mutton or pork and step surface by two achieves the axial limiting to shoe shaft 51 preferably.
The automotive brake assembly that the utility model embodiment provides, owing to being Spielpassung between its shoe shaft 51 and fixed hole of braking bottom board 61, only keep-spring need be taken off, the dismounting of brake shoe 21 can be carried out, and do not need to unload dust-proof cover 71, also need not knock from dust-proof cover 71 side, just can take out shoe shaft 51 from braking bottom board 61 easily, thus make the Renewal process of brake shoe 21 comparatively simple, facilitate the maintenance of brake shoe 21 widely.Meanwhile, this automotive brake assembly does not need to use shoe shaft fixing bolt, thus facilitates the installation of brake shoe 21 widely, decrease the use of component, reduce the cost of this automotive brake assembly, effectively simplify the structure, alleviate the weight of this automotive brake assembly preferably.
Have between two brake shoes in order to keep-spring 63 can be made and keep effect preferably, first keep-spring mounting hole 32 is near the first arc opening, as shown in Figure 6, thus make two brake shoes 21 can clamp shoe shaft 51 preferably and not easily skid off in movement process, simultaneously, the end of the first axle 53 can be pressed in after now keep-spring 63 installation, effectively prevent the axial float of shoe shaft 51, make this automotive brake assembly can keep braking effect preferably always.It should be noted that, the first keep-spring mounting hole 32 place can be provided with the first preformed hole 33, according to different usage requirements, can select the first preformed hole 33 or the first keep-spring mounting hole 32, be fixed keep-spring 63.
As shown in Figure 5, can be clamped in better on shoe shaft 51 in order to two brake shoes 21 can be made, the second braking tendons of beef, mutton or pork 41 can be provided with the second keep-spring mounting hole 42 near the second arc opening place, thus make the two sides of brake shoe 21 be provided with keep-spring 63, and then make the connection between two brake shoes 21 and shoe shaft 51 comparatively firm.Be understandable that, the second keep-spring mounting hole 42 place can be provided with the second preformed hole 43, with the installation requirements of flexible adaptation second keep-spring under different service condition better.
Further, be provided with return spring fixing pin 38 between the second end that second end and second of the first braking tendons of beef, mutton or pork 31 brakes the tendons of beef, mutton or pork 41, return spring fixing pin 38 be provided with the fixed groove matched with one end of return spring 62; The axis of return spring 62 is positioned in the plane at symmetrical line 81 place of brake shoe 21, namely after return spring 62 projects on brake shoe 21, the center of return spring 62 will be dropped on the symmetrical line 81 of brake shoe 21, as shown in Figure 7, efficiently avoid between return spring 62 and brake shoe 21 and produce the arm of force, considerably reduce the total run-out amount of the outer surface of brake shoe 21 during braking, effectively prevent automobile occur brake judder when braking and brake abnormal sound and sideslip, thus improve Security and the driving comfortability of automobile preferably.Meanwhile, make the friction disc wear on brake shoe 21 outer surface even, thus effectively extend the working life of brake shoe 21.When mounted, the two ends of return spring fixing pin 38, can be separately fixed in the return spring fixed hole 34 of the two braking tendons of beef, mutton or pork, return spring fixed hole 34 place can have the 3rd preformed hole 35, to complete the installation of return spring 62 under different usage requirements.
In order to the installation process between roller and brake shoe 21 can be made comparatively simple, can dismantle easily simultaneously, the second end that second end and second of the first braking tendons of beef, mutton or pork 31 brakes the tendons of beef, mutton or pork 41 all has the circular arc opening 37 matched with the outer surface of roll fixed shaft 64; Roll fixed shaft 64 is clamped in circular arc opening 37 by torque spring 65.When mounted, the two ends of torque spring stationary axle are arranged in the torque spring mounting hole 36 of the first braking tendons of beef, mutton or pork 31 and the second braking tendons of beef, mutton or pork 41, the assembly department of torque spring 65 is sleeved on torque spring stationary axle, one end of torque spring 65 is connected on brake shoe 21, and the other end of torque spring 65 is contained on roll fixed shaft 64.
As shown in Figure 8, become more for convenience in order to the installation of shoe shaft 51 can be made, the diameter of the first axle 53 equals the diameter of the second axle 54, thus make the generation need not considering the wrongly installed phenomenon caused because both diameters are different when mounted, thus cost savings the installation time of shoe shaft 51, reduce complexity during manufacture, improve manufacturing efficiency.
In order to shoe shaft 51 can be made to have higher intensity, be convenient to integration and produce, save fitting operation, the first axle 53, installation shaft 52 and the second axle 54 can form integral structure, thus effectively extend the working life of shoe shaft 51.
A kind of automobile that the utility model embodiment also provides, it comprises automotive brake assembly, the automotive brake assembly of this automotive brake assembly described by above-mentioned arbitrary technological scheme, because above-mentioned automotive brake assembly has above-mentioned technique effect, the automobile comprising above-mentioned automotive brake assembly also should have correspondingly technique effect.
The above is only preferred implementation of the present utility model, it is to be noted, these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model, and, after having read content of the present utility model, relevant technical staff in the field can make various change or amendment to the utility model, and these equivalent form of values fall into the application's appended claims limited range equally.
