Description
Technical Field
[0001] The present invention relates to the technical field of shock absorber detection equipment, and particularly relates to a shock absorber detection device with a disc brake. Background Art
[0002] Shock absorbers are widely used in automobiles, motorcycles, etc. To accelerate the attenuation of the vibration of the vehicle frame and body and improve the ride comfort of the vehicle. When passing through an uneven road surface, although the shock-absorbing spring can filter the road vibration, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring bounce. The shock absorption system is composed of a spring and a shock absorber. The shock absorber is not used to support the weight of the vehicle body, but to suppress the shock when the spring rebounds after absorbing shock and absorb the energy of the road impact. After the production and processing of the shock absorber, it is necessary to conduct an elasticity test on it to ensure the qualified performance and quality of the shock absorber.
[0003] The patent document with the application number CN202122843395.X discloses an elastic detection device for the processing of automotive shock absorbers, including a detection table. A load-bearing plate is fixed at the top of the detection table. A screw rod driven by a motor to rotate is arranged on one side of the detection table away from the load-bearing plate. A threaded block is threadedly sleeved on the screw rod. The top of the threaded block slides through the detection table and is fixed with a moving plate. A cylinder is installed on one side of the moving plate close to the load-bearing plate. The output end of the cylinder is fixed with a pressing plate. A bottom clamping seat for placing the shock absorber base is fixed on one side of the load-bearing plate close to the pressing plate. A top clamping seat for placing the shock absorber top seat is fixed on one side of the pressing plate close to the load-bearing plate. A laser sensor is installed at the top of the moving plate. A displacement block matching the position of the laser sensor is installed at the top of the pressing plate. A displacement display is installed on the front of the detection table. The laser sensor is electrically connected to the displacement display.
[0004] The above-mentioned elastic detection device for shock absorbers only drives the screw rod to rotate through a motor, so that the threaded block on the screw rod drives the moving plate to move towards the shock absorber, so that the device can be used to detect automotive shock absorbers of different specifications and sizes. Its simulation of the road conditions during the actual use of the shock absorber is not very good, resulting in inaccurate data detection of the shock absorber. Summary of the Invention

[0009] A mounting bracket, which is movably connected in the frame in the vertical direction and includes a shock absorber connecting portion. The shock absorber connecting portion cooperates with the simulated driving wheel to connect a shock absorber therebetween;
[0010] A driving and adjusting portion, which is rotatably arranged on the frame and is connected to the simulated driving wheel, and is used for driving the simulated driving wheel to rotate and intermittently moving away from the driving and adjusting portion;
[0011] A resistance adjusting portion, which is arranged on the frame and is used for increasing the resistance to the rotating simulated driving wheel.
[0012] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Embodiments
[0018] The present invention will be further described in detail through specific embodiments as follows:
[0019] As Figure 1 shown, an absorber detection device with a disc brake according to an embodiment of the present invention includes a frame 1, a simulated driving wheel 2, a mounting bracket 3, a driving adjustment part 4, and a resistance adjustment part 5;
[0020] Among them, the simulated driving wheel 2 is rotatably arranged on the frame 1;
[0021] The mounting bracket 3 is movably connected in the frame 1 along the vertical direction and includes an absorber connection part, and the absorber connection part cooperates with the simulated driving wheel 2 to connect the absorber therebetween;
[0022] The driving adjustment part 4 is rotatably arranged on the frame 1 and is connected to the simulated driving wheel 2, and is used to drive the simulated driving wheel 2 to rotate and intermittently move away from the driving adjustment part 4;
[0023] The resistance adjustment part 5 is arranged on the frame 1 and is used to increase the resistance to the rotating simulated driving wheel 2.
[0024] When the absorber detection device with a disc brake is in use, the position of the mounting bracket 3 is adjusted, the absorber is installed between the absorber connection part and the simulated driving wheel 2, the driving adjustment part 4 operates to drive the simulated driving wheel 2 to rotate, and the simulated driving wheel 2 is intermittently moved away from the driving adjustment part 4, then the absorber is intermittently adjusted in telescopic manner, and the resistance adjustment part 5 intermittently increases the resistance to the rotating simulated driving wheel 2; thereby simulating the spring force value load borne by the absorber when encountering undulating roads and relatively large frictional resistance, so as to detect the performance of the absorber.
[0025] In this embodiment: There are two simulated driving wheels 2 adopted, and the two simulated driving wheels 2 are arranged opposite to each other on the frame 1, and each simulated driving wheel 2 is provided with the absorber connection part, the driving adjustment part 4, and the resistance adjustment part 5 in a cooperative manner; thus enabling the absorber detection device with a disc brake to detect two absorbers simultaneously.
[0026] As Figure 3 , specifically, a support shaft 6 is inserted into the central hole of each simulated driving wheel 2, both ends of the support shaft 6 are connected to the frame 1 through a plurality of first tension springs 7, and one end of the support shaft 6 is fixedly connected to the absorber through a connection structure; a disc brake assembly 8 cooperating with the simulated driving wheel 2 is slidably arranged on the support shaft 6.
[0027] Here, the simulation driving wheel 2 is stably rotationally mounted on the frame 1 through the cooperation of the support shaft 6 and the plurality of first tension springs 7. The disc brake assembly 8 can be the disc brake assembly 8 installed on an existing automobile or motorcycle. The disc brake assembly 8 is controlled by a switch provided on the frame 1 to perform an emergency brake on the simulation driving wheel 2, so as to be able to detect the spring force value load borne by the shock absorber under the condition of emergency braking, and to detect the performance of the shock absorber.
[0028] The connection structure here may include a fixing hole opened in the support shaft 6 along its radial direction. One end of the shock absorber is inserted into the fixing hole and is connected by splines and abuts against the support shaft 6, so as to quickly fixedly connect one end of the shock absorber.
[0029] Such as Figure 1 and Figure 2 As shown in
[0030] According to another embodiment of the present invention, the shock absorber detection device with a disc brake, wherein the mounting bracket 3 further includes a frame body 31 movably connected in the frame 1 in the vertical direction. The shock absorber connecting portion is connected to the frame body 31. The shock absorber connecting portion includes an adjustment seat 32, a clamping and fixing structure, a first driving structure 33 and a second driving structure 34;
[0031] Wherein, one end of the adjustment seat 32 is rotatably connected to the frame body 31;
[0032] The clamping and fixing structure is slidably connected to the adjustment seat 32 and is used for fixedly connecting one end of the shock absorber;
[0033] The first driving structure 33 is rotatably arranged on the adjustment seat 32 and is connected to the clamping and fixing structure; it is used to drive the clamping and fixing structure to move towards or away from the simulation driving wheel 2;
[0034] In this embodiment: The frame body 31 is arranged above the simulation driving wheel 2. The first driving structure 33 and the second driving structure 34 can both be adjustment screws, and one end of each adjustment screw is fixedly connected with a handwheel; by rotating the handwheel in the second driving structure 34, the adjustment screw connected thereto rotates, so that the adjustment seat 32 rotates around its rotation connection point, thereby adjusting the angle of the adjustment seat 32; then rotating the handwheel in the first driving structure 33 to make the adjustment screw connected thereto rotate, the clamping and fixing structure moves towards or away from the corresponding simulation driving wheel 2, so that the shock absorber can be reasonably installed between the clamping and fixing structure and the simulation driving wheel 2; and because the angle of the adjustment seat 32 can be adjusted and the distance between the clamping and fixing structure and the simulation driving wheel 2 can be adjusted, different shock absorbers can be fixedly installed between the clamping and fixing structure and the simulation driving wheel 2 for detection.
[0035] Based on the above solution, in order to improve the stability of the adjusting seat 32, the shock absorber connecting portion further includes an angle adjustment limiting structure, which is connected between the middle parts of the frame body 31 and the adjusting seat 32 and is rotatably connected to the middle part of the adjusting seat 32, and is used for supporting and rotationally limiting the adjusting seat 32.
[0036] During the rotation of the adjusting seat 32, the angle adjustment limiting structure limits the rotation angle thereof. At the same time, after the angle of the adjusting seat 32 is adjusted, the angle adjustment limiting structure plays a supporting role for the adjusting seat 32, improving the stability of the adjusting seat 32, so that the shock absorber has sufficient stability after being connected between the clamping and fixing structure and the simulation driving wheel 2.
[0037] One of the shock absorber connecting portions includes an angle adjustment limiting structure, and whether to provide an angle adjustment limiting structure for the other can be selected according to requirements.
[0038] Furthermore, the adopted angle adjustment limiting structure includes an adjusting seat 32 positioning plate and a telescopic adjustment rod 36;
[0039] One end of the adjusting seat 32 positioning plate is rotatably connected to the frame body 31, and the other end is rotatably connected to the middle part of the adjusting seat 32;
[0040] One end of the telescopic adjustment rod 36 is rotatably connected to the middle part of the adjusting seat 32 positioning plate, and the other end is rotatably connected to the frame body 31.
[0041] In this embodiment: specifically, the adjusting seat 32 positioning plate is in a "V" shape, and the telescopic adjustment rod 36 is connected to the turning point of the adjusting seat 32 positioning plate; when the adjusting seat 32 rotates, the adjusting seat 32 positioning plate also rotates accordingly, and the telescopic adjustment rod 36 makes corresponding telescopic adjustments to limit and support the rotation of the adjusting seat 32.
[0042] Furthermore, the clamping and fixing structure includes a transverse connecting plate 37 slidably connected to the adjusting seat 32. Specifically, the transverse connecting plate 37 is slidably connected to the adjusting seat 32 through the cooperation of a chute and a slide rail. The transverse connecting plate 37 is threadedly connected to the adjusting screw in the first driving structure 33. The transverse connecting plate 37 is connected with a mounting plate 38 through a plurality of guide rods. The mounting plate 38 is slidably connected to the guide rods. A sensor 39 is connected between the mounting plate 38 and the transverse connecting plate 37. A connecting tooling 310 is connected to the mounting plate 38, and the connecting tooling 310 is fixedly connected to one end of the shock absorber; the sensor 39 collects the spring force value load borne by the shock absorber during the detection process, then transmits it to the controller, and then displays it on the display; the sensor 39, the controller and the display are all conventional electrical components.
[0043] Specifically, in this embodiment, the connecting tooling 310 includes a connecting screw rod fixedly connected to the mounting plate 38 by a nut. A connecting head is connected to the connecting screw rod. A fixing notch is formed at the end of the connecting head, and two oppositely arranged locking holes are formed on the inner wall of the fixing notch. One end of the shock absorber is inserted into the fixing notch, and then a pin is used to pass through the locking holes and the assembly holes on the end of the shock absorber, so as to quickly connect one end of the shock absorber.
[0044] As Figure 1 and Figure 3 shown, according to another embodiment of the present invention, in the shock absorber detection device with a disc brake, the resistance adjustment part 5 includes a resistance propulsion seat 51 and a linear mover 52;
[0045] Wherein, the resistance propulsion seat 51 is slidably arranged on the frame 1 and a resistance wheel 53 is rotatably connected thereto;
[0046] The linear mover 52 is fixedly arranged on the frame 1 and is connected to the resistance propulsion seat 51, and is used to drive the resistance propulsion seat 51 to approach or move away from the simulated driving wheel 2.
[0047] In this embodiment: the linear mover 52 can be a cylinder, and the telescopic adjustment of the cylinder is used to move the resistance propulsion seat 51 in the direction of approaching or moving away from the simulated driving wheel 2, so that the resistance wheel 53 moves in the direction of approaching or moving away from the simulated driving wheel 2; when the resistance wheel 53 moves to abut against the simulated driving wheel 2, at this time, the simulated driving wheel 2 is subjected to a large frictional resistance, and the spring force value load borne by the shock absorber in this case is tested to detect the performance of the shock absorber; when the resistance wheel 53 moves to disengage from the simulated driving wheel 2, the simulated driving wheel 2 continues to rotate under the drive of the drive adjustment part 4.
[0048] As Figure 1 shown, according to another embodiment of the present invention, in the shock absorber detection device with a disc brake, the drive adjustment part 4 includes a power unit 41, a drive wheel 42 and a test bump 43;
[0049] Wherein, the power unit 41 is rotatably arranged on the frame 1;
[0050] The drive wheel 42 is rotatably arranged on the frame 1 and the drive wheel 42 is connected to the power unit 41 through a transmission member, and the drive wheel 42 is in sliding contact with the simulated driving wheel 2 and transmits power by friction;
[0051] The test bump 43 is fixedly connected to the outer circumference of the drive wheel 42.
[0052] In this embodiment: The actuator 41 can be a motor, and the transmission member can be an existing belt drive structure. The motor provides power to drive through the belt drive structure so that the driving wheel 42 rotates. During the rotation of the driving wheel 42, it drives the cooperating simulated driving wheel 2 to rotate by frictional force. When the test bump 43 abuts against the simulated driving wheel 2 during the rotation of the simulated driving wheel 2, the simulated driving wheel 2 is driven to move a certain distance away from the simulated driving wheel 2. After the test bump 43 is disengaged from the simulated driving wheel 2, the simulated driving wheel 2 moves in the reverse direction to abut against the simulated driving wheel 2 again and continue to rotate. During this process, the shock absorber undergoes a telescopic adjustment to test the spring force value load it bears to detect the performance of the shock absorber.
[0053] As Figure 1 shown, according to another embodiment of the present invention, in the shock absorber detection device with disc brakes, a plurality of movable tension springs 9 connected to the frame 1 are circumferentially and uniformly distributed on the top of the frame body 31.
[0054] Since both the top of the frame 1 and the top of the frame body 31 are square, the number of movable tension springs 9 here is designed to be 4, which are respectively connected between the four corners of the top of the frame 1 and the top of the frame body 31 to movably connect the frame body 31 in the frame 1 and prevent the frame body 31 from being blocked from moving vertically in the frame 1.
[0055] Furthermore, a driver is provided on the top of the frame 1, and the driver is connected to the top of the frame body 31 through a worm and worm gear lift.
[0056] The driver here can be a motor, which provides power to drive through the worm and worm gear lift so that the frame body 31 moves vertically in the frame 1 to enable reasonable installation of different shock absorbers. Among them, the worm and worm gear lift is an existing structure. For example, it can be a micro worm and worm gear lift with an anti-rotation function in the patent application No. CN202123414044.3.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
