Description

Technical Field

[0001] The present application relates to the technical field of automobile brake systems, and in particular to a brake regulator. Background Art

[0002] Existing brakes usually use manual knobs or motors to adjust the braking force, but this method is prone to serious wear of internal parts after long-term use, which in turn leads to uneven braking force or even failure. In addition, traditional brake devices often do not have self-detection functions, making it difficult to monitor the braking status in real time and self-adjust in abnormal situations.

[0003] The role of the regulator in the braking system is to ensure that the braking system can work safely and effectively. The regulator can control the hydraulic or air pressure in the braking system to ensure that the braking force applied to each wheel is appropriate. In emergency braking or high-speed driving, the regulator can prevent the wheels from locking and maintain vehicle stability and control. The regulator plays a vital role in the braking system. It ensures that the vehicle can brake safely and stably under various driving conditions by accurately controlling the braking force.

[0004] The brake adjusters commonly used at this stage are one-way adjusters, which can only be adjusted in one direction, that is, they can only work when moving forward or backward.

[0005] Therefore, how to provide a brake regulator that has a self-detection function and can achieve bidirectional autonomous adjustment has become an urgent problem to be solved in the field. Utility Model Content

[0006] In order to provide a brake regulator that has a self-detection function and can achieve bidirectional autonomous adjustment, the present application provides a brake regulator.

[0007] The present application provides a brake regulator that adopts the following technical solution:

[0008] A brake adjuster comprises a mounting base, a nut movably connected to the mounting base, a screw threadedly connected to the nut, an end of the screw away from the nut being transmission-connected to the brake, the nut and the screw being symmetrically arranged in two groups, and an adjustment component for adjusting the relative position of the screw being arranged on the nut.

[0009] By adopting the above technical solution, when the brake is working, if the distance between the brake disc and the brake pad changes due to wear or other reasons, when the screw on one side is subjected to pressure, the screw transmits the pressure to the adjusting component through the nut, and the adjusting component drives the relative nut to rotate after being subjected to pressure, thereby achieving distance adjustment; two sets of symmetrically arranged nuts and screws and the adjusting component can achieve two-way automatic adjustment, which is more flexible.

[0010] Preferably, the adjustment assembly includes a pressure plate sleeved on the outer circumferential surface of the nut and a leaf spring arranged on one side of the pressure plate, the pressure plate and the leaf spring are connected together, one end of the leaf spring away from the pressure plate cooperates with the nut, and a fixing assembly for fixing the pressure plate is provided on the mounting base.

[0011] By adopting the above technical solution, the distance between the brake disc and the brake pad changes, and the screw on one side will be subjected to pressure. The screw transmits the pressure to the pressure plate through the nut. The pressure plate is squeezed under the action of pressure, which in turn causes the leaf spring connected to it to move, thereby driving the nut in contact with it to rotate slightly, thereby achieving distance adjustment.

[0012] Preferably, the fixing assembly comprises a first fixing frame and a second fixing frame which are installed on the mounting base, and the first fixing frame and the second fixing frame are provided with a clearance groove for the pressing sheet to pass through.

[0013] By adopting the above technical solution, the setting of the first fixed frame and the second fixed frame provides support and limiting functions for the pressing plate, thereby improving the overall stability of the regulator during operation, and the setting of the yield groove provides space for the leaf spring to pass through the first fixed frame and the second fixed frame.

[0014] Preferably, the top and bottom of the first fixing frame and the second fixing frame are both provided with elastic buckles, the end faces of the elastic buckles are provided with arc surfaces, and the elastic buckles are respectively engaged with the first fixing frame and the second fixing frame.

[0015] By adopting the above technical solution, the setting of the elastic clip makes it easier for the operator to strengthen the connection between the first fixed frame and the second fixed frame. The elastic clips are provided on the top and the bottom to make the reinforcement effect more stable. The setting of the arc surface on the end face of the elastic clip makes it easier for the operator to connect the first fixed frame and the second fixed frame.

[0016] Preferably, the first fixing frame and the second fixing frame are provided with fixing rods for fixing the leaf spring, and the fixing rods pass through the leaf spring and abut against the first fixing frame and the second fixing frame.

[0017] By adopting the above technical solution, the setting of the fixing rod makes it easier for operators to fix the leaf spring, making the leaf spring more stable during operation, and the fixing rod can further reinforce the entire regulator.

[0018] Preferably, a limiting frame is provided between the first fixing frame, the second fixing frame and the leaf spring, the pressing sheet passes through the limiting frame, and the limiting frame abuts against the leaf spring.

[0019] By adopting the above technical solution, the setting of the limit frame plays a supporting and pressing role on the leaf spring, making the regulator more stable when working.

[0020] Preferably, a positioning groove for plugging and fitting the leaf spring is provided on the mounting base, and a clearance hole for plugging the leaf spring is provided on the first fixing frame and the second fixing frame.

[0021] By adopting the above technical solution, the operator first installs the pressing plate on the nut, and then the operator fixes the first fixed frame and the second fixed frame on the mounting base. Then the operator installs the limit frame on the side walls of the first fixed frame and the second fixed frame. Then the operator installs the leaf spring on the positioning groove of the mounting base through the make way hole. The setting of the positioning groove facilitates the operator to position and install the leaf spring.

[0022] Preferably, a fixing threaded hole for fixing the mounting base is formed on a side surface of the mounting base.

[0023] By adopting the above technical solution, the operator fixes the mounting base to the mounting base plate by bolts, thereby fixing the regulator as a whole.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the brake is working, if the distance between the brake disc and the brake pad changes due to wear or other reasons, when the screw on one side is under pressure, the screw transmits the pressure to the adjustment component through the nut. The adjustment component drives the relative nut to rotate after being under pressure, thereby adjusting the distance; two sets of symmetrically arranged nuts and screws and the adjustment component can realize two-way automatic adjustment, which is more flexible;

[0026] 2. When the distance between the brake disc and the brake pad changes, the screw on one side will be under pressure, and the screw transmits the pressure to the pressure plate through the nut. The pressure plate is squeezed under the action of pressure, which in turn causes the leaf spring connected to it to move, thereby driving the nut in contact with it to rotate slightly, thereby achieving distance adjustment;

[0027] 3. The setting of the first fixed frame and the second fixed frame provides support and limiting functions for the pressing plate, thereby improving the overall stability of the regulator during operation, and the setting of the concession groove provides space for the leaf spring to pass through the first fixed frame and the second fixed frame.

[0033] The following is combined with Figures 1-3 This application is described in further detail.

[0034] The present application embodiment discloses a brake regulator. Figure 1 , Figure 2 A brake adjuster includes a mounting base 1, which is arranged horizontally. A nut 11 is arranged on the mounting base 1, which is arranged horizontally. The nut 11 is movably connected to the mounting base 1, and a circle of teeth is arranged on the outer peripheral surface of the nut 11 away from the mounting base 1. A screw 12 is threadedly connected to the nut 11. The screw 12 is arranged horizontally, and the end surface of the screw 12 extending out of the nut 11 is connected to the brake in a transmission manner. Two groups of nuts 11 and screws 12 are symmetrically arranged about the mounting base 1, and an adjustment component 2 for adjusting the relative position of the screw 12 is arranged on the nut 11.

[0035] Reference Figure 1 , Figure 2 The adjusting assembly 2 includes a pressing piece 21 and a leaf spring 22. The pressing piece 21 is vertically arranged, and the pressing piece 21 is sleeved on the outer peripheral surface of the nut 11. The pressing piece 21 is vertically arranged, and the pressing piece 21 is arranged in contact with the nut 11. The leaf spring 22 is arranged on one side of the pressing piece 21, and the leaf spring 22 is vertically arranged. The leaf spring 22 is connected to the pressing piece 21, and the end of the leaf spring 22 away from the pressing piece 21 is matched with the nut 11.

[0036] When the brake is working, if the distance between the brake disc and the brake pads changes due to wear or other reasons, this regulator will be triggered to start operating. When the screw 12 on one side is under pressure, the pressing piece 21 on the same side will be squeezed. Since the pressing piece 21 is connected to the leaf spring 22, the leaf spring 22 will act, driving the nut 11 in contact with it to rotate, thus realizing the adjustment of the distance. If the distance on the other side changes, another set of pressing piece 21 and leaf spring 22 will be triggered to work. That is, when one side receives pressure and needs to reduce the distance, the adjusting component 2 drives the nut 11 on the other side to rotate to adjust the distance, so that the distance can be maintained in a relatively fixed state, thus realizing two-way self-adjustment.

[0037] Refer to Figure 1 、 Figure 2 , a fixing component 3 for fixing the pressing piece 21 is arranged on the mounting base 1. The fixing component 3 includes a first fixing frame 31 and a second fixing frame 32. Both the first fixing frame 31 and the second fixing frame 32 are vertically arranged, and both the first fixing frame 31 and the second fixing frame 32 are wrapped outside the mounting base 1. The setting of the first fixing frame 31 and the second fixing frame 32 provides support and limitation for the pressing piece 21, thereby improving the overall stability of the regulator during operation.

[0038] Refer to Figure 1 、 Figure 2 , elastic buckles 34 are arranged at the top and bottom of the first fixing frame 31 and the second fixing frame 32. The end face of the elastic buckle 34 is provided with an arc surface 35. When the operator installs the first fixing frame 31 and the second fixing frame 32 on the mounting base 1, the elastic buckle 34 is clamped on the adjacent fixing frame under the action of the arc surface 35. The setting of the elastic buckle 34 further strengthens the connection between the first fixing frame 31 and the second fixing frame 32, and the setting of the arc surface 35 facilitates the operator to fix the first fixing frame 31 and the second fixing frame 32.

[0039] Refer to Figure 1 、 Figure 2 , a fixing rod 4 for fixing the leaf spring 22 is arranged on the first fixing frame 31 and the second fixing frame 32. The fixing rod 4 is vertically arranged, and the fixing rod 4 passes through the leaf spring 22 and abuts against the first fixing frame 31 and the second fixing frame 32. The setting of the fixing rod 4 facilitates the operator to further strengthen the fixing of the leaf spring 22, and at the same time can also make the overall regulator more stable.

[0040] Refer to Figure 1 、 Figure 2 , a limiting frame 41 is arranged between the first fixing frame 31, the second fixing frame 32 and the housing. The limiting frame 41 is vertically arranged, and the limiting frame 41 abuts against the leaf spring 22. The setting of the limiting frame 41 plays a supporting role for the leaf spring 22, making the regulator more stable during operation.

[0041] Refer to Figure 2 , a positioning groove 13 is formed in the mounting base 1, and a relief hole 33 is formed in the first fixing frame 31 and the second fixing frame 32. The operator positions and installs the leaf spring 22 through the positioning groove 13, and the relief holes 33 in the first fixing frame 31 and the second fixing frame 32 provide relief for the installation of the leaf spring 22.

[0042] Refer to Figure 3 , a fixing threaded hole 42 for fixing the mounting base 1 is formed on one side of the mounting base 1. The operator can fix and install the mounting base 1 on the mounting base plate through the bolt and the fixing threaded hole 42, thereby fixing the whole regulator.

[0043] The implementation principle of a brake regulator in an embodiment of the present application is as follows: When the brake is working, if the distance between the brake disc and the brake pads changes due to wear or other reasons, the screw 12 connected to the brake will be subjected to pressure at this time. The screw 12 transmits the received pressure to the pressing piece 21 on the same side through the nut 11. The pressing piece 21 is extruded under the action of the pressure, and then the connected leaf spring 22 is actuated, thereby driving the nut 11 in contact with it to rotate slightly, so as to realize the adjustment of the distance; Two groups of screws 12, nuts 11, pressing pieces 21 and leaf springs 22 are provided to realize autonomous two-way adjustment, thereby ensuring safe and stable braking of the vehicle under various driving conditions.

[0044] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application based on this, therefore: Any equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
