Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate directions
The positional or positional relationship is based on that shown in the drawings and is for convenience of description and simplicity of illustration only
Rather than indicating or implying that the device or element so referred to must have a particular orientation, be constructed and arranged in a particular orientation
Operation, and therefore, should not be construed as limiting the invention. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
A suspension system is arranged between two opposite wheels and comprises a frame 3, a first plate body 10, a second plate body 20 and a shock absorber 4, the two first connecting rods 1 and the two second connecting rods 2 are arranged up and down, the two first connecting rods 1 are respectively connected with the frame 3 and the first plate body 10 at two ends of the first connecting rods 1, the two second connecting rods 2 are arranged up and down, the frame 3 and the second plate body 20 are respectively connected with two ends of the second connecting rods 1, the first plate body 10 and the second plate body 20 are respectively connected with two wheel axles, the first plate body 10 and the second plate body 20 are both parallel to the frame 3, the two first connecting rods 1, the frame 3 and the first plate body 10 form a deformable parallelogram structure, the two second connecting rods 2, the frame 3 and the second plate body 20 form a deformable parallelogram structure, the frame 3 is perpendicular to a vehicle centerline plane and is located at the central position of the two deformable parallelogram structures, and the two ends of the shock absorber 4 are respectively connected with the two deformable parallelogram structures. As can be seen from the attached drawings, in particular fig. 1 and 6, in a standard structure on flat ground, the suspension system of this type is basically composed of two articulated deformable parallelogram members symmetrical with respect to the median plane of the vehicle, sharing a same frame 3, and the upper first link 1 and second link 2 of which are connected to a shock absorber 4, the shock absorber 4 being of a telescopic tube type structure.
In this embodiment, the upper end of the frame is provided with a U-shaped recess along the direction perpendicular to the vehicle centerline plane, the two axial ends of the shock absorber 4 are respectively hinged to the first connecting rod 1 and the second connecting rod 2, and the middle part of the shock absorber 4 is located in the U-shaped recess and can move up and down along the direction perpendicular to the vehicle centerline plane.
With reference to fig. 2, 3 and 4, it is illustrated that the two first links 1, the frame 3 and the first plate 10 form a deformable parallelogram structure, and the two second links 2, the frame 3 and the second plate 20 form a deformable parallelogram structure, which are geometrically symmetric and share the same frame 3, and the frame 3 is perpendicular to the centerline plane of the vehicle and is located at the center of the two parallelogram structures. When the two parallelogram blocks are deformed by partial rotation of the lever around the hinge point A, B, C, D, E, F, the first plate 10 and the second plate 20 can keep them parallel to the frame 3; the first plate 10 and the second plate 20 are rigidly connected to the wheel by the first pivot pin 11 and the second pivot pin 21.
In this embodiment, a shock absorber 4 kinematically connects the two articulated parallelogram links and is connected to the upper first link 1 and second link 2, whose articulation ends correspond to G and H, respectively. In the parking situation shown in fig. 3, the two wheels R1 and R2 can remain perfectly vertical, with the shock absorber 4 being compressed after the two parallelogram elements have undergone different deformations. In contrast, as shown in fig. 4, when the vehicle turns, the damper 4 does not react, i.e., keeps its own length constant, because the first link 1 and the second link 2 of the two parallelogram blocks are simultaneously rotated at the same angle. In this mode, the load plane tends to be inside the curve (rolling motion) to achieve a balance between centrifugal force and gravity, just like a two-wheeled vehicle.
As shown in fig. 6, an anti-roll device is provided on a suspension system, and comprises a first forming plate 6, a second forming plate 7, a first transmission rod 5A, a second transmission rod 5B, a caliper 12 and a brake disc 9, wherein the first forming plate 6 and the second forming plate 7 rotate around a shaft 8, two ends of the shaft 8 are provided on a vehicle body frame, the first forming plate 6 is connected with the brake disc 9 into a whole, the second forming plate 7 is connected with the brake caliper 12 into a whole, two ends of the first transmission rod 5A are hinged to a first connecting rod 1 and the first forming plate 6, two ends of the second transmission rod 5B are hinged to a second connecting rod 2 and the second forming plate 7, and when the caliper 12 locks the brake disc 9, the relative rotation of the first forming plate 6 and the second forming plate 7 is prevented, and further the rotation of the first transmission rod 5A and the second transmission rod 5B and the first connecting rod 1 and the second connecting rod 2 is prevented.
When the vehicle starts, the motion is transmitted from the first link 1 and the second link 2 above the suspension system to the first and second forming plates 6 and 7 of the anti-roll apparatus through the transmission rod 5A and the transmission rod 5B. The first and second shaped plates 6, 7 are both rotated about an axis 8 constituted by one axis pin, the second shaped plate 7 is integral with the caliper 12, and the first shaped plate 6 is integral with the brake disc 9, when the anti-roll device is activated, the caliper 12 locks the brake disc 9, preventing the relative rotation of the first and second shaped plates 6, 7 and therefore of the first and second transmission levers 5A, 5B and of the first and second connecting rods 1, 2 of the suspension system, locking the whole anti-roll device, the only possible movement is the rotation about the axis 8, thus enabling the shock absorber 4 to function. In this mode, the vehicle cannot tilt sideways, while the rear suspension can perform its function by lowering when the vehicle is loaded on the loading plane, in particular when the vehicle is stopped and the loading operation is carried out.
With regard to the way in which the anti-roll device operates, firstly it is automatically activated when the parking brake is applied, and secondly it can be activated by the driver by means of a lever, pedal or special push button. Again, a mode may also be provided in which the system is automatically activated when the vehicle is travelling below a certain speed. Of course, modifications or variations of the suspension system and anti-roll device are possible without affecting the above-described operating characteristics, but are ensured within the scope of the invention.
A tricycle comprising a suspension system on which an anti-roll device is provided, it has to be mentioned that the anti-roll device can be applied to different suspensions having the same characteristics as the articulated suspension system.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
