Description

Technical Field

[0001] The utility model relates to the technical field of vehicle shock absorption, in particular to a hydraulic suspension rotating wheel assembly. Background Art

[0002] The vehicle's suspension balance device is a general term for the elastic connection device between the frame and the wheels, which can mitigate the impact force on the vehicle during driving and improve the stability of the vehicle's driving and handling. Existing heavy-duty AGVs, flatbed transporters and other transport vehicles use a relatively complex suspension balance device structure, which is cumbersome to connect with the vehicle chassis. In addition, the suspension balance device lacks a steering structure and can only play a shock-absorbing role, but cannot improve the flexibility of vehicle driving. Utility Model Content

[0003] The utility model aims to provide a hydraulic suspension rotating wheel assembly, which has a simple and compact structure, can make the wheels rotate at any angle, and can effectively balance the adhesion of each wheel, thereby improving the stability of the suspension balancing device.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hydraulic suspension rotating wheel assembly, including a support frame and a lifting cylinder, the lifting cylinder is arranged above the support frame, a slewing support is installed between the support frame and the lifting cylinder, a driving motor is arranged on one side of the slewing support, the top of the lifting cylinder is fixedly connected to the vehicle chassis, and a driven wheel group is installed at the bottom of the support frame. The driven wheel group includes a driven wheel frame, and a plurality of driven wheels are rotatably connected to the driven wheel frame.

[0005] Optionally, the driven wheel frame is rotatably connected to the support frame via a frame pin.

[0006] Optionally, a cylinder flange is installed on the outer periphery of the lifting cylinder, and a guide rod is arranged on the top of the cylinder flange.

[0007] Optionally, the lifting cylinder includes a cylinder body and a piston, the piston is slidably connected in the cylinder body, a piston sealing ring is provided on the inner wall of the cylinder body, the end of the piston and the cylinder body form a hydraulic space, and hydraulic oil is added to the hydraulic space.

[0008] Optionally, there are four driven wheels, a wheel axle is installed on the driven wheel frame, the four driven wheels are connected to the wheel axle through spherical roller bearings for uniform rotation, bearing sleeves are arranged on both sides of each spherical roller bearing, and an oil baffle is installed on the outer side of the outermost driven wheel.

[0009] The hydraulic suspension rotating wheel assembly of the utility model has the following advantages:

[0010] (1) The driven wheel group can move up and down with the lifting cylinder, playing a shock-absorbing and buffering role. The slewing support can make the driven wheel frame rotate to any angle under the drive motor, thereby realizing the steering of the vehicle. The overall structure of the device is simple and compact, which is conducive to simplifying the structure of the vehicle chassis, facilitating the connection with the vehicle chassis, and saving space.

[0011] (2) The driven wheel frame can rotate left and right. When driving on uneven roads, both left and right wheels can touch the ground, thereby improving the stability of the device.

[0012] (3) The guide rod cooperates with the vehicle chassis to play a guiding role, which can improve the stability of the driven wheel group when the lifting cylinder drives it to rise and fall. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 3 As shown, a hydraulic suspension rotating wheel assembly includes a support frame 1 and a lifting cylinder 2. The lifting cylinder 2 is arranged above the support frame 1. A slewing support 3 is installed between the support frame 1 and the lifting cylinder 2. A driving motor 4 is arranged on one side of the slewing support 3. The top of the lifting cylinder 2 is fixedly connected to the vehicle chassis. A cylinder flange 5 is installed on the outer periphery of the lifting cylinder 2. A guide rod 6 is arranged on the top of the cylinder flange 5. The guide rod 6 matches the vehicle chassis and plays a guiding role, which can improve the stability of the lifting cylinder 2 when driving the driven wheel group 11 to rise and fall.

[0021] like Figure 4As shown, the lifting cylinder 2 includes a cylinder body 7 and a piston 8. The piston 8 is slidably connected in the cylinder body 7. A piston sealing ring 9 is provided on the inner wall of the cylinder body 7. The end of the piston 8 and the cylinder body 7 form a hydraulic space 10. Hydraulic oil is added to the hydraulic space 10. The driven wheel group 11 can move up and down with the lifting cylinder 2, thereby playing a role of buffering and shock absorption and improving stability.
