Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hydraulic retarder and specifically relates to a shock absorbing plate for hydraulic retarder. BACKGROUND

[0002] The hydraulic retarder is an auxiliary braking device of a vehicle, and the transmission shaft of the vehicle drives the rotor to rotate, so that the working liquid flows between the rotor and the stator to generate a reverse resistance torque, thereby achieving braking and converting kinetic energy into heat energy for dissipation. The hydraulic retarder is commonly used in large passenger cars, heavy trucks and the like. The electromagnetic proportional valve in the hydraulic retarder plays a crucial role in the hydraulic retarder. During the braking process of the vehicle, when the driver steps on the brake pedal or the electronic control system of the vehicle issues a braking instruction, the electromagnetic proportional valve accurately adjusts the amount and pressure of the working liquid entering the working chamber of the hydraulic retarder according to the received electrical signal, and by changing the pressure and flow of the working liquid, the braking torque generated by the hydraulic retarder can be adjusted, thereby achieving accurate control of the deceleration process of the vehicle and enabling the vehicle to decelerate smoothly and safely.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 5The adjustment assembly 200 includes an adjustment plate 210, which is slidably connected to the inner cavity of the square groove 110. Positioning through grooves 211 are opened on both the front and rear sides of the adjustment plate 210. A sliding groove 212 is opened on the top of the inner wall of the positioning through groove 211. A positioning toothed plate 213 is fixedly connected to the bottom of the inner wall of the positioning through groove 211. A positioning toothed block 214 meshes with the top of the positioning toothed plate 213. A mounting stud 215 is fixedly connected to the middle of the top of the positioning toothed block 214. The top of the mounting stud 215 extends through the sliding groove 212 to the outside of the base plate 100, and the outer wall of the mounting stud 215 is slidably connected to the inner wall of the sliding groove 212. A fixing block 216 is screwed onto the outer wall of the mounting stud 215, located within the inner cavity of the positioning through groove 211. The top of the fixing block 216 contacts the top of the inner wall of the positioning through groove 211. The left side of the inner wall of the square groove 110 is open to the left side of the square groove 110. A counteracting lead screw 220 is rotatably connected via a bearing. The right end of the counteracting lead screw 220 extends to the outer side of the base plate 100.

By adjusting the position of the positioning tooth block 214 and the adjustment plate 210, the position of the mounting stud 215 is adjusted accordingly. Thus, when facing electromagnetic proportional valves of different sizes, the position of the mounting stud 215 corresponds to the connection hole on the electromagnetic proportional valve, which greatly improves the overall applicability.

[0034] Please refer to this carefully. Figure 1 , Figure 2 , Figure 4 and Figure 6The shock absorption assembly 300 includes a buffer spring 310. A shock absorption cavity 120 is formed on the top of the base plate 100. There are four shock absorption cavities 120, located between two square grooves 110. The buffer spring 310 is fixedly connected to the bottom of the inner wall of the shock absorption cavity 120. A buffer block 311 is fixedly connected to the top of the buffer spring 310. The outer wall of the buffer block 311 is slidably connected to the inner wall of the shock absorption cavity 120, and a sealing ring is provided between the outer wall of the buffer block 311 and the inner wall of the shock absorption cavity 120. A support rod 312 is fixedly connected to the middle of the top of the buffer block 311. The tops of the four support rods 312 extend to the outer side of the base plate 100 and are fixedly connected to a mounting plate 313. The top of the mounting plate 313 is provided with… The device has a soft rubber layer 320 and a hard rubber layer 321 on top of the soft rubber layer 320. The front and rear side walls of the base plate 100 have connection ports 330 located below the damping chamber 120. The two front damping chambers 120 and the two rear damping chambers 120 are respectively connected to the connection ports 330 on the front and rear sides. The damping plate of the hydraulic retarder buffers and damps the vibration generated by the electromagnetic proportional valve through the damping component 300. It can reduce the large impact force in the early stage, so that the vibration after the initial buffering is relatively stable and gentle. Then, the soft rubber layer 320 and the hard rubber layer 321 handle the remaining vibration, which can better absorb and transform low-frequency and small-amplitude vibrations. They work together to improve the overall damping effect.

[0035] In use, this utility model works as follows: Rotating the toggle block 230 drives the opposing lead screw 220 to rotate. The rotation of the opposing lead screw 220 causes the two adjusting plates 210 to move oppositely within the two square grooves 110. The lateral spacing of the mounting studs 215 is adjusted according to the lateral spacing of the connection holes of the electromagnetic proportional valve. Then, rotating the fixing block 216 releases the fixing of the positioning tooth block 214. Pulling the mounting studs 215 upwards causes the positioning tooth block 214 to disengage from the positioning tooth plate 213. Next, the mounting studs 215 slide through the sliding groove 212. The movement of the mounting studs 215 simultaneously drives the positioning... The toothed block 214 moves, and after reaching its position, it is pressed down by the mounting stud 215, thereby engaging the positioning toothed block 214 with the positioning toothed plate 213. By rotating the fixing block 216 to contact the top of the positioning through groove 211, the fixing block 216, in conjunction with the mounting stud 215, fixes the positioning toothed block 214, thus securing the mounting stud 215. Similarly, the remaining mounting studs 215 are adjusted to align their positions according to the longitudinal position of the connection hole of the electromagnetic proportional valve. The connection hole on the electromagnetic proportional valve is then inserted into the corresponding mounting stud. After the stud 215 is installed, it is secured by a nut and corresponding rubber washer, allowing the electromagnetic proportional valve to contact the hard rubber layer 321, thus installing the electromagnetic proportional valve. During use, when vibration occurs, the electromagnetic proportional valve moves downwards through the hard rubber layer 321 and the soft rubber layer 320, causing the mounting plate 313 to move downwards. As the mounting plate 313 moves downwards, it causes the support rod 312 to move downwards. The movement of the support rod 312 causes the buffer block 311 to slide downwards within the damping chamber 120. The movement of the buffer block 311 compresses the buffer spring 310, causing it to contract. This buffers and dampens the electromagnetic proportional valve. At the same time, when the buffer block 311 moves, it pushes the air in the damping chamber 120 out through the connection port 330, thereby buffering the large impact force in the early stage of vibration. When the buffer block 311 is in place, the remaining vibration is absorbed and rotated by the hard rubber layer 321 and the soft rubber layer 320. After the damping is completed, the buffer spring 310 drives the buffer block 311 to reset. During the reset, the buffer block 311 is evacuated through the connection port 330, so that when the buffer spring 310 rebounds, it can reset slowly and evenly to avoid secondary vibration.
