Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
The first embodiment is as follows:
as shown in fig. 1, the steel back body of the present embodiment includes a body 4, a protection plate 1 and a stiffener, wherein the stiffener further includes an abutting portion 7 and an extending portion 8.
As shown in fig. 2, the cross section of the body 4 is a dovetail structure having side plates 9 at both sides of the body 4 in the extending direction, the body 4 and the side plates 9 at both sides thereof form a dovetail structure, the inner side thereof is used for mounting a fixed friction body, and the outer side thereof is used for engaging with a mounting frame for mounting the body 4.
As shown in fig. 1-3, the protection plate 1 is disposed on the body 4, during driving and braking of the vehicle, the body 4 has a movement tendency in the mounting bracket, the protection plate 1 is disposed at one end of the body 4 having the movement tendency and is abutted to the mounting bracket, and the steel back body may vibrate and impact with the mounting bracket due to the reciprocating movement tendency during driving and braking, in this embodiment, the protection plate 1 and the mounting bracket vibrate and impact, so that damage of the body 4 caused by the vibration and impact can be reduced, the steel back body is more wear-resistant and impact-resistant, the service life is longer, and the mounting bracket in this embodiment is also generally called a brake pad holder.
The protection plate 1 is in a trapezoid structure with the height parallel to the extending direction of the body 4, as shown in fig. 1, the protection plate 1 is in a trapezoid shape, the height of the protection plate is perpendicular to the upper bottom 2 and parallel to the extending direction of the body 4, the protection plate has the upper bottom 2 and the waist 3 positioned at two sides of the upper bottom 2, and the height of the trapezoid is introduced for the purpose of describing the structure of the protection plate clearly and is a relative concept, so the height of the trapezoid is not marked in the drawing. The upper bottom 2 and the mounting bracket butt of guard plate 1 have between curb plate 9 and the waist 3 and set for clearance 6, and the effect of setting for clearance 6 is in order to make the time, conveniently adjusts the position of the waist 3 of guard plate 1, because guard plate 1 is the trapezium structure and has and sets for clearance 6, can prevent that guard plate 1 and current mounting bracket from taking place to interfere when the installation, can install in current mounting bracket for the commonality is good.
And the one end that has the trend of moving of the edge body 4 of curb plate 9 on the body 4 is located the inboard of guard plate 1, the waist 3 of 1 both sides of guard plate with can effectively avoid curb plate 9 and mounting bracket to take place the vibration impact, curb plate 9 is protected by the waist 3 of 1 both sides of guard plate promptly, the upper end 2 and the mounting bracket butt of guard plate 1 make the vehicle in driving and braking process, avoid producing the displacement, reduce vibration and impact for steel backing body long service life.
The strengthening rib sets up along 4 extending direction of body, and its butt portion 7 is connected with the extension 8 that sets up along 4 extending direction of body, and butt portion 7 and extension 8 constitute T style of calligraphy structure, butt portion 7 and 1 fixed connection of guard plate, the other end of strengthening rib and the one end parallel and level of keeping away from guard plate 1 of body 4, and T style of calligraphy structure makes extension 8 have better support to butt portion 7, makes guard plate 1 have better impact resistance.
When using, with the one end butt joint of keeping away from guard plate 1 of two steel back of the body install on the mounting bracket, because the other end of strengthening rib and the one end parallel and level of keeping away from guard plate 1 of body 4 can make the area of contact of two steel back of the body in the one end butt joint department of keeping away from guard plate 1 increase, consequently the butt joint is more firm.
In addition, body 4 still includes backup pad 5, and backup pad 5 sets up towards the inboard space of body 4, and backup pad 5 has two rows that set up along the 4 extending direction of body, and backup pad 5 makes this steel back of the body and frictional body firm in connection, and with 8 fixed connection of extension, has better limiting displacement to the strengthening rib for the impact resistance of steel back of the body can be better.
As shown in fig. 1, four support plates 5 are in one group, and have a plurality of groups, and any group is two, and the body 4 between two is fretwork, and the support plate 5 is made through the mode of mould panel beating shaping.
Example two:
the synthetic brake pad comprises a steel back body and a friction body connected with the steel back body, when the synthetic brake pad is used, the synthetic brake pad is installed on the installation frame, and when the speed needs to be reduced, the friction body of the synthetic brake pad is in contact with a vehicle brake disc so as to reduce the speed of a vehicle.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
