Description

Technical Field

[0001] The utility model provides a reinforcing plate structure of an automobile brake bottom plate, and relates to the technical field of automobile brakes. Background Art

[0002] Automobile brakes are the braking devices of automobiles. Brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of drum brakes is the brake drum, whose working surface is a cylindrical surface; the rotating element of disc brakes is a rotating brake disc, whose end surface is the working surface. The brake base plate is a key part in automobile brakes. The brake base plate is used to fix the support parts of the brake shoe assembly and the brake drum assembly. In order to better use the brake base plate and extend its service life, the brake base plate needs to be strengthened.

[0003] When the brake is applied to the vehicle, a huge friction force is generated between the brake and the brake pad. The brake base plate is fixed to the vehicle body. At this time, the brake base plate needs to withstand a huge torsional force. If the brake base plate cannot withstand the torsional force, the brake base plate will be deformed first, or even the brake will be scrapped. Therefore, the brake base plate needs to be reinforced. The existing base plate reinforcement plate generally uses bolts to connect the reinforcement plate and the base plate, but the nuts are prone to loosening, resulting in the separation of the brake base plate and the reinforcement plate.

[0004] Therefore, it is necessary to provide a reinforcement plate structure for a bottom plate of an automobile brake that can prevent the connection between the reinforcement plate and the bottom plate from loosening. Utility Model Content

[0005] In order to overcome the disadvantage of the prior art that bolts are generally used to connect the reinforcing plate and the bottom plate, but the nuts are prone to loosening, the utility model provides a car brake bottom plate reinforcing plate structure which prevents the connection between the reinforcing plate and the bottom plate from loosening.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a vehicle brake base plate reinforcement plate structure, including a brake base plate, a mounting seat, a rivet and a reinforcement plate, the brake base plate is fixedly connected to the mounting seat, two rivets are pierced on the mounting seat, a reinforcement plate is installed on the brake base plate, the reinforcement plate and the brake base plate are jointly provided with a mounting hole, the reinforcement plate and the brake base plate are jointly provided with an axial hole in the middle, and also include a fixed through hole and a hexagonal groove, the brake base plate and the reinforcement plate are both provided with a plurality of fixed through holes, and the fixed through holes on the reinforcement plate are provided with a hexagonal groove.

[0007] Preferably, the reinforcing plate is of a special shape and is embedded in the brake bottom plate.

[0008] Preferably, it further comprises a plurality of positioning columns fixedly connected to the brake base plate, and the reinforcing plate is positioned by the positioning columns so as to be embedded in the brake base plate.

[0009] Preferably, it also includes a plurality of heat dissipation openings on the brake base plate, and a heat dissipation grille is installed in each heat dissipation opening of the brake base plate.

[0010] Preferably, it also includes threading holes which are jointly opened on the brake bottom plate and the reinforcing plate, and a protective sleeve is arranged in the threading hole.

[0011] Preferably, it also includes a plurality of threaded holes jointly opened on the brake base plate and the reinforcement plate, and flat head bolts are threadedly arranged in the threaded holes.

[0012] Compared with the prior art, the bottom reinforcement plate provided by the embodiment of the utility model has the following advantages: 1. By first embedding the nut into the hexagonal groove, and then using the bolt to penetrate the vehicle body firmware and penetrate the fixed through hole from the bottom of the brake bottom plate, the bolt and the nut are threadedly connected, and the nut is limited by the hexagonal groove, so that the bolt and the nut will not rotate or loosen, thereby achieving the effect of preventing the connection between the reinforcement plate and the bottom plate from loosening.

[0013] 2. The reinforcement plate can be quickly positioned and embedded into the brake base plate through the positioning column. At the same time, when the reinforcement plate and the brake base plate are connected by bolts, the positioning column can also prevent the reinforcement plate from rotating with the bolts, thereby achieving the effect of positioning and limiting the reinforcement plate.

[0014] 3. The heat generated by braking can be dissipated to the outside through the heat dissipation port to avoid heat accumulation in the brake. The heat dissipation grille can prevent foreign matter from entering the heat dissipation port and blocking it, thereby achieving the effect of dissipating heat for the brake.

[0015] 4. The protective cover can prevent direct friction between the handbrake cable and the edge of the threading hole, so as to avoid significant wear on the handbrake cable and extend the service life of the handbrake cable.

[0016] 5. By using a flat head bolt threadedly arranged in the threaded hole, the reinforcing plate is prevented from automatically detaching from the brake base plate after the brake base plate is removed from the vehicle body, thereby achieving the effect of strengthening the connection between the reinforcing plate and the brake base plate.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Embodiment 1: A reinforcing plate structure for a brake bottom plate of an automobile, see Figure 1-Figure 3 As shown, it includes a brake base plate 1, a mounting seat 2, a rivet 201 and a reinforcing plate 3. The mounting seat 2 is fixed to the brake base plate 1 by welding. Two rivets 201 for fixing the brake shoe are pierced on the mounting seat 2. A reinforcing plate 3 is installed on the brake base plate 1. The reinforcing plate 3 is special-shaped and embedded in the brake base plate 1 so that the reinforcing plate 3 will not easily rotate on the brake base plate 1. A mounting hole 301 for installing a brake wheel cylinder is jointly provided on the reinforcing plate 3 and the brake base plate 1. An axial hole 4 for passing a drive shaft is jointly provided in the middle of the reinforcing plate 3 and the brake base plate 1. It also includes a fixing through hole 5 and a hexagonal groove 501. Four fixing through holes 5 are provided around the axial hole 4 on the brake base plate 1 and the reinforcing plate 3. A hexagonal groove 501 for limiting a nut is provided at the fixing through hole 5 on the reinforcing plate 3.

[0025] When assembling the brake, the reinforcement plate 3 is embedded on the brake base plate 1, and the nut is first embedded in the hexagonal groove 501, and then the bolt is used to penetrate the vehicle body firmware and penetrate the fixed through hole 5 from the bottom of the brake base plate 1, so that the bolt and the nut are threadedly connected. At this time, the nut is limited by the hexagonal groove 501, and the bolt and the nut will not rotate in the fixed through hole 5, and the bolt and the nut are not easy to loosen; the brake wheel cylinder can be installed at the installation and mounting hole 301, and the brake shoe can be installed on the mounting seat 2 through two rivets 201. The brake wheel cylinder installed on the mounting hole 301 pushes the two brake shoes to rotate around the rivet 201, so that the brake shoe and the brake drum are in contact and friction for braking; the shaft hole 4 is used to penetrate the drive shaft that drives the vehicle to rotate.

[0026] Example 2: Based on Example 1, refer to Figure 2 and Figure 3 As shown, it also includes four positioning columns 6 fixed to the brake base plate 1 by welding, and the reinforcing plate 3 is positioned by the positioning columns 6 to be embedded in the brake base plate 1.

[0027] When the reinforcing plate 3 needs to be installed on the brake base plate 1, the reinforcing plate 3 can be quickly positioned and embedded in the brake base plate 1 through the positioning column 6. At the same time, when the reinforcing plate 3 and the brake base plate 1 are connected by bolts, the positioning column 6 can also prevent the reinforcing plate 3 from rotating with the bolts.

[0028] See also Figure 4 As shown, there are also four heat dissipation openings 7 opened on the brake base plate 1 for heat dissipation of the brake shoe, and a heat dissipation grille 8 is embedded in each heat dissipation opening 7 of the brake base plate 1.

[0029] When the brake shoe and the brake drum perform friction braking, the brake shoe will generate a lot of heat. At this time, the heat can be dissipated to the outside through the heat dissipation port 7 to avoid heat accumulation in the brake. The heat dissipation grille 8 can prevent foreign matter from entering the heat dissipation port 7 and blocking it.

[0030] See also Figure 5 As shown, it also includes a threading hole 9 which is jointly opened on the brake bottom plate 1 and the reinforcing plate 3, and a protective sleeve 901 made of rubber material is embedded in the threading hole 9.

[0031] The threading hole 9 is used for threading the handbrake line. The protective cover 901 can prevent the handbrake line from directly rubbing against the edge of the threading hole 9, thereby avoiding significant wear on the handbrake line and extending the service life of the handbrake line.

[0032] See also Figure 5 As shown, it also includes four threaded holes 10 which are jointly opened on the brake base plate 1 and the reinforcement plate 3, and the threaded holes 10 are provided with flat head bolts 1001 in the form of threads.

[0033] In addition to using bolts connecting the vehicle body fasteners to fix the brake base plate 1 and the reinforcement plate 3, the reinforcement plate 3 and the brake base plate 1 can also be reinforced by using flat head bolts 1001 threadedly arranged in the threaded hole 10 to prevent the reinforcement plate 3 from automatically detaching from the brake base plate 1 after the brake base plate 1 is removed from the vehicle body.
