Description

Technical Field

[0001] The present invention relates to the field of automotive control devices, and particularly to a new type of suspension transverse torsion bar mechanism. Background Art

[0002] In existing vehicles, the Panhard rod and the anti-roll bar are important components of the vehicle.

[0003] Among them, the Panhard rod has a fixed length and connects the vehicle body and the axle, ensuring good handling stability and anti-roll ability during vehicle driving. When the vehicle turns or passes through a bumpy road under heavy load, the Panhard rod can keep the relative position between the vehicle body and the axle within the designed range.

[0004] The anti-roll bar is a torsion bar spring made of spring steel, mostly in a "U" shape, horizontally arranged at the front and rear ends of the vehicle, and used in cooperation with the front suspension and the rear suspension; the middle part of the rod body is connected to the vehicle body or the frame with a rubber bushing, and both ends are connected to the suspension guide arm through rubber pads or ball joints at the side wall ends; its function is to prevent the vehicle body from experiencing excessive lateral roll during turning, keep the vehicle body balanced as much as possible, reduce the degree of lateral roll of the vehicle, and improve ride comfort.

[0005] In the prior art, the Panhard rod and the anti-roll bar are installed on the vehicle separately, and there is no vehicle torsion bar that integrates the functions of the Panhard rod and the anti-roll bar. Summary of the Invention

[0006] The purpose of the present invention is to provide a new type of suspension transverse torsion bar mechanism, which simultaneously has the connection and fixation function of the Panhard rod and the anti-torsion and stabilization functions of the anti-roll bar.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A new type of suspension transverse torsion bar mechanism includes a torsion bar main body. Both ends of the torsion bar main body are movably connected to the axle. A moving block is arranged on the side wall of the torsion bar main body. The moving block is connected to a driving device, and the driving device is arranged on a support plate, and the support plate is movably connected to the vehicle frame.

[0008] Preferably, the moving block is movably arranged on the support plate.

[0009] Preferably, the support plate is connected to the vehicle frame through a floating device.

[0010] Preferably, the floating device is a spring.

[0011] Preferably, a fixed shaft is arranged on the axle; Both ends of the torsion bar main body are provided with translation blocks. A round hole is arranged on the translation block, and a rubber bushing that cooperates with the fixed shaft is installed in the round hole.

[0012] Preferably, a first bending portion is provided in the middle of the torsion bar body, and the moving block is arranged on the side wall of the first bending portion.

[0013] Preferably, second bending portions are provided at both ends of the torsion bar body, and the second bending portions are connected to the translation blocks.

[0014] Preferably, the moving block is a rack, and the driving device includes a motor and a gear, and the gear meshes with the rack.

[0015] Preferably, a protective cover is arranged outside the rack and the gear.

[0016] Preferably, the driving device is a cylinder, and the telescopic end of the cylinder is connected to the torsion bar body through the moving block.

[0017] The beneficial effects of the present invention are as follows: 1. The two ends of the torsion bar body of the present invention are movably connected to the axle, and the middle part is movably connected to the vehicle frame through the driving device, so that its fixed installation is reliable, and at the same time, it can move to a certain extent, improving the handling performance of the vehicle.

[0018] 2. The torsion bar body of the present invention can reciprocate under the drive of the gear through the rack, and continuously adjust the left - right length change within a certain range. When the torsional characteristics of the suspension system need to take effect, the torsion bar body simultaneously has the ability to control the relative position of the vehicle body and the axle and the ability of the vehicle to resist lateral torsion, and at the same time has the advantages of a Panhard rod and a stabilizer bar, optimizing the handling characteristics of the suspension system.

[0019] 3. The pallet of the present invention is connected to the vehicle frame through the floating device. Since the height of the torsion bar body changes during the movement process, the floating device makes the movement process smoother and the experience better.

[0020] 4. Second bending portions are provided on the torsion bar body, increasing the rigidity of the device and making the torsion bar body have stronger stability. A first bending portion is also provided on the torsion bar body, making the cooperation position of the rack and the gear closer to the vehicle frame, shortening the length of the spring and making the shock absorption performance of the device better.

[0022] The accompanying drawings are only for illustrative purposes and should not be construed as limiting the patent; for a better illustration of this embodiment, some components in the drawings are omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. Detailed implementation mode

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Embodiment 1 As Figure 1 and Figure 2 shown, a novel suspension transverse torsion bar mechanism according to an embodiment of the present invention includes a torsion bar main body 2. Both ends of the torsion bar main body 2 are movably connected to the axle 1. The torsion bar main body 2 can move left and right along the axle 1. A moving block 22 is welded to the side wall of the torsion bar main body 2. The moving block 22 is connected to a driving device. The driving device is used to drive the moving block 22 and the torsion bar main body 2 to move left and right. The driving device is arranged on a support plate 3. The support plate 3 is movably connected to the vehicle frame (the vehicle frame is not shown in the drawings). When the torsion bar main body 2 moves left and right along the axle 1, the support plate 3 will move up and down along the vehicle frame accordingly.

[0025] The moving block 22 is movably arranged on the support plate 3. The support plate 3 only bears the moving block 22, so that the moving block 22 can move left and right along the support plate 3. During the driving process of the vehicle, the axle 1 will move up and down. When the axle 1 moves down, it drives the torsion bar main body 2 and the moving block 22 to move down, pressing down the support plate 3; when the axle 1 moves up, it drives the torsion bar main body 2 and the moving block 22 to move up. When the moving block 22 moves up, it drives the driving device to move up, and then drives the support plate 3 to move up.

[0026] In this embodiment, the moving block 22 is a rack. The driving device includes a motor 31 and a gear 33. The gear 33 meshes with the rack. The motor 31 is arranged on the support plate 3. During the up and down movement of the axle 1, it will drive the torsion bar main body 2 to move up and down. By arranging the gear 33 (through the motor 31) on the support plate 3, the two can always maintain a good meshing state.

[0027] A protective cover is arranged outside the rack and the gear 33 to prevent foreign objects from entering.

[0028] When the motor 31 drives the gear 33 to rotate, it drives the rack and the torsion bar main body 2 connected to the rack to move left and right. During the left and right movement of the torsion bar main body 2, it will also move up and down, driving the rack to move up and down. During the up and down movement of the rack, it drives the support plate 3 and the gear 33 to move up and down, so that the gear and rack maintain a good meshing state.

[0029] In some embodiments, the same function can be achieved by a screw mechanism, an electro-hydraulic mechanism or a worm and worm gear, and the driving device can also be a cylinder, an oil cylinder or other devices that can drive the gear to rotate.

[0030] The pallet 3 is connected to the vehicle frame through a floating device 32, and the floating device 32 is a spring. Since the motor 31 is arranged on the pallet 3, one end of the spring can be fixed outside the motor 31 (or the fixed housing outside the motor), and the other end of the spring is connected to the vehicle frame. During the up and down movement of the torsion bar main body 2, the floating device 32 can also reduce the vibration caused by it and improve the handling experience.

[0031] A fixed shaft 11 is arranged on the axle 1; translation blocks 21 are welded to both ends of the torsion bar main body 2, a round hole 23 is arranged on the translation block 21, and a rubber bushing matched with the fixed shaft 11 is installed in the round hole 23. When the rack is driven by the gear 33 to move, the torsion bar main body 2 is driven to move. At this time, the translation blocks 21 move synchronously. During this process, the rubber bushing is squeezed and deformed, making the movement process smoother and avoiding phenomena such as jamming during the movement.

[0032] A first bending part 24 is arranged in the middle of the torsion bar main body 2, and the moving block is arranged on the side wall of the first bending part 24. The first bending part 24 makes the matching position of the rack and the gear closer to the vehicle frame, shortens the length of the spring, and makes the shock absorption performance of the device better.

[0033] Second bending parts 25 are arranged at both ends of the torsion bar main body 2, and the second bending parts 25 are connected to the translation blocks 21. The second bending parts 25 increase the rigidity of the device and make the torsion bar main body have stronger stability.

[0034] Compared with a straight rod, by arranging the first bending part 24 and the second bending part 25, during the movement or jumping of the axle 1, the force will not be directly transmitted to the motor 31 and the gear 33, which can play a role in protecting the motor 31 and the meshing gears 33 and the rack.

[0035] During use, the motor 31 can also be connected to the vehicle's entire wiring through a power cord, and an adjustment switch is added to the vehicle instrument panel; when the user or driver needs to adjust the torsion bar main body 2, the rotation direction and the stroke in the rotation direction of the motor 31 and the gear can be adjusted through the adjustment switch on the instrument panel to achieve the adjustment purpose.

[0036] Embodiment Two In this embodiment, the driving device is set as a cylinder, and the telescopic end of the cylinder is connected to the torsion bar main body 2 through a moving block 22, and the moving block 22 is respectively connected to the torsion bar main body 2 and the telescopic end of the cylinder.

[0037] Through the telescoping of the cylinder, the moving block 22 and the torsion bar main body 2 are driven to move.

[0038] Meanwhile, one end of the spring in this embodiment can be fixed to the outside of the air cylinder (or a fixed housing outside the air cylinder), and the other end of the spring is connected to the vehicle frame.

[0039] During use, the air cylinder can also be connected to the vehicle's entire wiring through a power cord, and an adjustment switch is added to the vehicle instrument panel; when a user or driver needs to adjust the torsion bar body 2, the telescopic direction and stroke of the air cylinder can be adjusted through the adjustment switch on the instrument panel to achieve the adjustment purpose.
