Example 1

The present embodiment relates to a brake caliper frame that can optimize the installation space of a brake on a knuckle 2; an exemplary structure thereof is shown in fig. 1.

In general, the brake caliper frame comprises a frame body 4, wherein at least two connecting holes for connecting the knuckle 2 are formed in the frame body 4, and the two connecting holes are asymmetrically arranged relative to the center line of the frame body 4.

Of course, the brake 7 of the present embodiment may be a fixed caliper brake or a floating caliper disc brake; however, the brake caliper according to this embodiment is particularly suitable for mounting a floating caliper disc brake, and the brake 7 shown in fig. 1 is a floating caliper disc brake.

Specifically, the frame body 4 of the present embodiment includes a connecting beam 44, an inner bracket provided at one end of the connecting beam 44, and an outer bracket provided at the other end of the connecting beam 44; the connecting hole is provided on the inner bracket for fixing the frame body 4 to the knuckle 2. The arrangement of the inner bracket and the outer bracket at the two ends of the connecting beam 44 forms a clamping mode for the brake disc 1, and is convenient for respectively assembling the friction plates 70 on the inner bracket and the outer bracket, thereby forming the clamping of the brake disc 1 and realizing a reliable braking effect.

In the present embodiment, the connecting beams 44 are two symmetrically arranged with respect to the center line (i.e., the frame center line 406 shown in fig. 2), and the inner bracket includes a first inner connecting arm 41 provided on one of the connecting beams 44, a second inner connecting arm 42 provided on the other connecting beam 44, and an inner reinforcing beam 43 connected between the first inner connecting arm 41 and the second inner connecting arm 42. Specifically, the first inner connecting arm 41 and the second inner connecting arm 42 are each bent and extended from the end of the connecting beam 44 toward the same side, and the length of the second inner connecting arm 42 is longer than that of the first inner connecting arm 41. Based on the above arrangement, the connecting holes of the present embodiment include a first connecting hole 403 provided at the connecting portion of the first inner connecting arm 41 and the inner reinforcing beam 43, and a second connecting hole 404 provided at the connecting portion of the second inner connecting arm 42 and the inner reinforcing beam 43. In this way, the two connecting holes are asymmetrically arranged about the center line 406 of the frame body, and a space for arranging the friction plate 70 is formed between the first inner connecting arm 41 and the second inner connecting arm 42, so that the friction plate 70 is convenient to arrange, and a good basic condition is provided for the braking action of the friction plate 70.

Of course, the brake 7 includes two sets of friction plates 70, respectively disposed on the inner and outer brackets. In this embodiment, referring to FIG. 2, friction plate 70 is slidably disposed within mounting groove 405 on the inner frame. In this embodiment, the middle parts of the first inner connecting arm 41 and the second inner connecting arm 42 are respectively provided with a mounting groove 405, and the ears at the two ends of the friction plate 70 are respectively slidably disposed in the two mounting grooves 405, so that the friction plate 70 slides between the two mounting grooves 405, thereby meeting the action requirement of the friction plate 70.

The outer bracket comprises two outer connecting arms 45 and an outer reinforcing beam 46 connected between the two outer connecting arms 45; the two outer connecting arms 45 are respectively connected with the two connecting beams 44, and are respectively bent and formed at the other ends of the connecting beams 44 relative to one ends of the connecting beams 44 connected with the inner support. Friction plate 70 on the outer bracket is disposed between the two outer connecting arms 45.

For the asymmetric arrangement of the two connecting holes, the two connecting holes can be flexibly adjusted in a reasonable range. As shown in fig. 2, in the present embodiment, an angle β is formed between a line 407 connecting the centers of the first connection hole 403 and the second connection hole 404 and a perpendicular 408 to the center line 406 of the frame body, and preferably, the angle β satisfies: beta is more than or equal to 10 degrees and less than or equal to 15 degrees; for example, it may be set to 10 °, 11.5 °, 13.2 °, 14 °, 15 °, or the like.

Referring to fig. 3 in the second embodiment, the frame 4 is of an asymmetric design, and is adapted to the position conditions of the brake 7. The design ensures that the first clamp frame mounting frame 22 on the steering knuckle 2 does not protrude too much, and the central connecting line of the two penetrating holes 220 can be more approximate to the vertical direction; the center line of the two mounting grooves 405 (i.e. the length direction of the friction plate 70) may be inclined to coincide with the tangent line of the brake disc 1 where the two mounting grooves are located, so that the friction plate 70 can exert a good braking effect. The designed structure has good strength performance and lighter weight of the frame body 4; the space between the first inner connecting arm 41 and the second inner connecting arm 42 for accommodating the friction plate 70 also satisfies the mounting requirement of the friction plate 70, and the interference between the inner reinforcing beam 43 and the friction plate 70 does not occur. Preferably, the included angle β (approximately the inclination angle of the friction plate 70 relative to the inner reinforcement beam 43) between the two connecting lines is set to 13.2 °, so that the strength of the frame body 4 can be improved while the weight of the caliper frame is reduced, the arrangement space of the friction plate 70 on the frame body 4 is optimized, and the problem that the existing symmetrical brake caliper mounting bracket cannot be arranged when being matched with the fixed caliper 3 is solved.

In the present embodiment, a guide pin hole is provided at one end of the connection inner bracket of the connection cross member 44, and the actuator of the brake 7 is mounted on the frame body 4 via the guide pin 5 inserted into the guide pin hole. Specifically, the other end of the first inner link arm 41 is provided with a first guide pin hole 401, and the other end of the second inner link arm 42 is provided with a second guide pin hole 402, with respect to one end of the link inner reinforcement beam 43. A guide pin hole is provided at one end of the first and second inner connection arms 41 and 42 extending toward the outside of the brake disc 1, facilitating the penetration of the guide pin 5 and the assembly of the actuator.

In summary, taking the installation of the floating caliper disc brake as an example, the brake caliper frame of the present embodiment separately sets the fixed caliper 3 and the floating caliper in the floating caliper disc brake at two sides of the knuckle 2, and the floating caliper is set at the lower position of the knuckle 2, so that the connection arrangement space of the pull rod connecting frame 23 and the pull rod ball pin 6 is formed above the installation position of the floating caliper, and the non-central symmetrical arrangement form of the fixed caliper 3 and the floating caliper makes the arrangement of the floating caliper disc brake, the pull rod connecting frame 23 and the fixed caliper 3 on the knuckle 2 more balanced, each has a relatively wide assembly space, avoids mutual interference, and is convenient for the installation operation of related parts, thereby optimizing the installation arrangement space of the floating caliper disc brake on the knuckle 2.

In the present embodiment, the fixed caliper 3 and the brake 7 are provided on the left and right sides of the knuckle 2, respectively, and the brake 7 is mounted on the knuckle 2 using the brake caliper frame provided in the first embodiment.

Specifically, the fixed caliper 3 and the brake 7 of the present embodiment are arranged around the center of the knuckle 2 (i.e., around the axis of the brake disc 1 to which the knuckle 2 corresponds), and, for the angle α between the center line of the fixed caliper 3 and the center line of the brake 7 (i.e., the frame body center line 406), it is preferable that the angle α satisfies 140 ° Σ 160 °, for example, it may be set to 140 °, 145 °, 150 °, 155 °, 160 ° or the like.

The center of the steering knuckle 2, namely the axle center of the brake disc 1 corresponding to the steering knuckle 2 is used as a round dot, the fixed clamp 3 and the brake 7 are arranged around the round dot, and an included angle alpha formed by the fixed clamp 3 and the brake 7 and the round dot is set between 140 degrees and 160 degrees, so that the included angle between the fixed clamp 3 and the brake 7 on the side where the pull rod connecting frame 23 is located is at least greater than 200 degrees, thereby providing enough space for the arrangement of the pull rod connecting frame 23 and further preventing the possibility of interference between the pull rod ball pin 6 and the brake 7 on the pull rod connecting frame 23.

Wherein, the brake 7 is arranged on the steering knuckle 2 through the frame body 4, and a first clamp frame mounting frame 22 is formed on one side of the lower part of the steering knuckle 2; the fixed jaw 3 is then mounted on a second jaw mount 21 on the knuckle 2 by means of a fixed jaw. Meanwhile, two penetrating holes 220 for connecting the frame body 4 are formed in the first jaw mounting frame 22 at intervals. The frame body 4 for installing the brake 7 is installed on the first clamp frame installation frame 22 on the steering knuckle 2, and the frame body 4 can be firmly fixed on the steering knuckle 2 by adopting bolts through arranging the connecting through holes 220, so that the connection mode is simple to operate and the connection performance is reliable.

Based on the arrangement condition of the penetrating hole 220 and the first connection 403 and the second connection hole 404 correspondingly arranged on the first clamp frame installation frame 22, two bolts for the installation frame body 4 sequentially penetrate through the installation hole and the penetrating hole 220, and then the installation of the frame body 4 can be completed. The positions of the first connection 403 and the second connection hole 404 can provide a reliable connection base for the frame body 4, so that the frame body 4 can be firmly connected to the knuckle 2.

Example III

The present embodiment relates to a vehicle employing the brake system provided in the second embodiment.

By adopting the braking system and the brake clamp frame thereof, the fixed clamp 3 and the brake 7 are arranged at intervals on the arc determined by the outer contour of the brake disc 1, and the arc is divided into a major arc section and a minor arc section by the fixed clamp 3 and the brake 7; the tie rod connecting frame 23 on the knuckle 2 corresponds to the major arc, has good arrangement space, can avoid interference with the brake 7, provides good conditions for the installation and arrangement of the fixed clamp 3, the brake 7 and the tie rod ball pin 6 on the knuckle 2, and has the technical advantages of the brake clamp frame in the first embodiment.
