[0036] The embodiment of the present invention provides a brake, and this brake is applicable to a vehicle, such as Figures 1 to 3 as shown, the brake includes two brake discs 110 and a plurality of friction plates 120. The two brake discs 110 are adapted to be connected to a wheel. The plurality of friction plates 120 are arranged corresponding to the two brake discs 110. The plurality of friction plates 120 are respectively arranged in pairs on both sides of the brake discs 110. At least one friction plate 120 moves under the action of a driving source, and the movement of at least one friction plate 120 drives at least one brake disc 110 and other friction plates 120 to move, so that the plurality of friction plates 120 are respectively clamped to the two brake discs 110.

[0037] According to the brake of the present application, a single driving source can drive a plurality of friction plates 120 to clamp two brake discs 110, realizing the braking of a double-disc brake system. The structure is simple and compact, the volume is smaller, and the overall cost and weight of the system are smaller. The plurality of friction plates 120 can be synchronously driven by a single driving source, having high synchronism, the overall braking performance of the system is more stable, and the response time of the system braking is faster.

[0038] In one embodiment, as Figure 1 shown, the two brake discs 110 include a first brake disc 111 and a second brake disc 112. The first brake disc 111 is fixedly connected to the wheel, and the second brake disc 112 is movably arranged on the wheel. The first brake disc 111 and the second brake disc 112 are spaced apart along the axial direction X, and the second brake disc 112 can move in a direction close to or away from the first brake disc 111.

[0039] In a detailed embodiment, the first brake disc 111 is fixed to the wheel axle 100, such as Figure 3As shown, the second brake disc 112 is movably disposed on the wheel axle 100 and can move along the axial direction X of the wheel axle 100 to move in a direction closer to or away from the first brake disc 111.

[0040] In one embodiment, as Figure 1 shown, a plurality of friction plates 120 include a first friction plate 121 and a second friction plate 122. The first friction plate 121 is adapted to move under the action of a driving source. The movement of the first friction plate 121 drives the movement of the second brake disc 112, and the movement of the second brake disc 112 in turn drives the movement of the second friction plate 122. The second friction plate 122 includes at least one friction plate 120. Among them, the second friction plate 122 can be one or two.

[0041] In the embodiment as Figure 1 shown, there are two first friction plates 121 and two second friction plates 122.

[0042] In embodiments not shown in other figures, the first friction plate 121 can also be three and the second friction plate 122 can be one.

[0043] In the embodiment as Figure 1 shown, the first friction plate 121 includes a No. 1 friction plate 123 and a No. 2 friction plate 124. The first brake disc 111 and the second brake disc 112 are located between the No. 1 friction plate 123 and the No. 2 friction plate 124. There are two second friction plates 122, including a No. 3 friction plate 125 and a No. 4 friction plate 126, which are disposed between the first brake disc 111 and the second brake disc 112, so that the first brake disc 111 and the second brake disc 112 respectively correspond to two friction plates 120. When the braking system implements braking, under the action of the driving source, the movement of the No. 1 friction plate 123 and the No. 2 friction plate 124 drives the movement of the second brake disc 112, and the movement of the second brake disc 112 drives the movement of the No. 3 friction plate 125 and the No. 4 friction plate 126, so that the first brake disc 111 is clamped by the No. 1 friction plate 123 and the No. 4 friction plate 126, and the second brake disc 112 is clamped by the No. 2 friction plate 124 and the No. 3 friction plate 125, thereby achieving braking.

[0044] In embodiments not shown in other figures, the No. 3 friction plate 125 or the No. 4 friction plate 126 can move in the same way as the No. 1 friction plate 123 and the No. 2 friction plate 124 under the action of the driving source. Among the No. 1 friction plate 123, the No. 2 friction plate 124, the No. 3 friction plate 125 or the No. 4 friction plate 126 driven by the driving source, one of them drives the movement of the second brake disc 112, and the movement of the second brake disc 112 drives the movement of the other of the No. 3 friction plate 125 or the No. 4 friction plate 126. At this time, the first friction plate 121 is three and the second friction plate 122 is one.

[0045] As shown Figure 1 In the figure, the brake further includes a first elastic member 130 disposed between the first brake disc 111 and the second brake disc 112. That is, the first end of the first elastic member 130 is connected to the first brake disc 111, and the other end is connected to the second brake disc 112. Under the action of the drive source, the No. 1 friction plate 123 and the No. 2 friction plate 124 move, pushing the second brake disc 112 to move along the axial direction X close to the first brake disc 111, thereby squeezing the first elastic member 130. When the braking system releases the brake, the first elastic member 130 pushes the second brake disc 112 to return by elastic potential energy.

[0046] In one embodiment, the brake further includes a second elastic member 131. The first end of the second elastic member 131 is connected to the second brake disc 112, and the other end is connected to the limiting member 101 of the wheel axle 100. The limiting member 101 is disposed on the side of the second brake disc 112 away from the first brake disc 111 to assist the second brake disc 112 to return.

[0047] As shown Figure 1 In the figure, the brake further includes a fixing bracket 140 adapted to be connected to the vehicle body. Specifically, the fixing bracket 140 is connected to the chassis steering knuckle 142 by fixing bolts 141. The No. 1 friction plate 123 is mounted on the fixing bracket 140 and is adapted to move under the action of the drive source.

[0048] As shown Figure 1 In the figure, the brake further includes a moving bracket 150 movably disposed on the fixing bracket 140. Specifically, the moving bracket 150 is connected to the fixing bracket 140 by a guide pin 151 and is adapted to move along the axial direction X of the guide pin 151 under the action of the drive source. The No. 2 friction plate 124 is also disposed on the moving bracket 150. The movement of the No. 2 friction plate 124 drives the movement of the second brake disc 112, and the movement of the second brake disc 112 drives the movement of the second friction plate 122.

[0049] In some embodiments, a rubber dust cover 152 is further disposed on the guide pin 151. The first end of the rubber dust cover 152 is connected to the moving bracket 150, and the second end is connected to the fixing bracket 140, thereby facilitating the prevention of foreign objects and dust from entering the guide hole and preventing the movement of the moving bracket 150 relative to the fixing bracket 140 from being disturbed. In addition, when the braking system releases the brake, the rubber dust cover 152 can also provide a part of the elastic potential energy for the return of the moving bracket 150.

[0050] Further, a piston 160 is also provided on the moving frame 150. A cavity 161 is formed between the piston 160 and the moving frame 150. The cavity 161 is adapted to be connected to a driving source. The piston 160 pushes the No. 1 friction plate 123 to move under the action of the driving source. Specifically, the housing of the piston 160 is fixed to the moving frame 150, and the moving end of the piston 160 can contact the No. 1 friction plate 123. A part of the cavity 161 of the piston 160 is adapted to communicate with an external driving source. The driving source here can be a hydraulic pump. A hydraulic pipe 162 is connected to the cavity 161 of the piston 160, and the hydraulic pipe 162 is connected to the inlet oil passage 163 of the driving source. When braking is implemented, high-pressure brake fluid enters the cavity 161 of the piston 160 through the inlet oil passage 163 and the hydraulic pipe 162, pushing the piston 160 to move. The moving end of the piston 160 can push the No. 1 friction plate 123 to contact the outer side of the first brake disc 111 (the outer surface refers to Figure 1 the right side of the first brake disc 111 in

[0051] In some embodiments, as Figure 1 shown, the brake further includes a sliding member 170. The sliding member 170 is provided on the moving frame 150. The sliding member 170 is located between the first brake disc 111 and the second brake disc 112. The second friction plate 122 is provided on the sliding member 170, that is, the No. 3 friction plate 125 and the No. 4 friction plate 126 are provided on the sliding member 170. The movement of the second brake disc 112 drives the sliding member 170 to move. Specifically, as Figure 2 shown, the sliding member 170 is nested in the card slot of the moving frame 150 and can move along the axial direction X. Under the action of the driving source, the piston 160 pushes the No. 1 friction plate 123 to clamp the outer side of the first brake disc 111. At the same time, the No. 2 friction plate 124 contacts the outer side of the second brake disc 112 and generates a braking torque. Then, it pushes the second brake disc 112 to slide along the axial direction X and in the direction close to the first brake disc 111. The movement of the second brake disc 112 drives the sliding member 170 to move together. Furthermore, the inner side of the second brake disc 112 (the inner side refers to the right side of the second brake disc 112) contacts the No. 3 friction plate 125 to generate a braking torque, and the No. 4 friction plate 126 contacts the inner side of the first brake disc 111 (the inner side refers to Figure 1 the left side of the first brake disc 111 in

[0052] In some embodiments, as Figure 1 shown, the brake further includes a third elastic member 132. There are two third elastic members 132. One end of the third elastic member 132 is connected to the sliding member 170, and the other end of the third elastic member 132 is connected to the moving frame 150. When the second brake disc 112 returns to its original position and drives the moving frame 150 to return to its original position, the third elastic member 132 enables the central symmetric return of the sliding member 170. The elastic member can be a return spring or an elastic steel bar. The purpose of setting the elastic member is to provide elastic potential energy for the return of the second brake disc 112 and the sliding member 170 when the braking system releases the brake.

[0053] In one embodiment, the No. 1 friction plate 123 is also provided with an elastic member (not shown in the figure). The first end of the elastic member is connected to the fixed frame 140, and the second end of the elastic member is connected to the No. 1 friction plate 123. The setting of the elastic member enables the No. 1 friction plate 123 to move relative to the fixed frame 140 in the axial direction X. When the piston 160 moves under the action of the driving source, it pushes the No. 1 friction plate 123 to move in the axial direction X away from the fixed frame 140, so as to clamp the outer side of the first brake disc 111. When the piston 160 returns to its original position under the action of the driving source, the No. 1 friction plate 123 can be separated from the first brake disc 111 under the elastic action of the elastic member, thereby preventing the first brake disc 111 from being hindered by the dragging force of the No. 1 friction plate 123. The elastic member can be a spring or an elastic steel bar.

[0054] The present application also provides a vehicle, including the brake according to the above. The vehicle according to the present application improves the braking effect, and can achieve the clamping of the two brake discs 110 with a single driving source, simplifies the structure of the brake, improves the stability of the brake, and speeds up the response time of the braking system.
