Description

Technical Field

[0001] The utility model relates to the technical field of coil springs, in particular to a rear coil spring structure for automobile suspension shock absorption. Background Art

[0002] A coil spring is a coil of elastic steel rod that is stretched or compressed during the vertical movement of the wheel to deform, absorbing the kinetic energy of the wheel and converting it into potential energy of the spring, thereby reducing the direct impact on the car body.

[0003] The torsion spring itself does not have a damping effect, but only a buffering function. In actual applications, it needs to be used in conjunction with a shock absorber, which can effectively absorb most of the vibration energy and achieve smooth driving of the vehicle.

[0004] Coil springs and dampers are connected to the vehicle frame and suspension. The suspension includes independent suspension and non-independent suspension. The wheels on both sides of the non-independent suspension are connected to the axle through rigid connectors, so the movement of the wheel on one side will directly affect the movement of the wheel on the other side. The wheels of the independent suspension are connected to the vehicle frame through their own independent suspension to avoid the two wheels affecting each other. However, when turning and encountering large bumps, they cannot provide good support for lateral forces and each performs shock absorption separately, which affects the shock absorption effect. Therefore, we propose a rear coil spring structure for automobile suspension shock absorption. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a rear coil spring structure for automobile suspension shock absorption, which solves the problem that the movement of the wheel on one side of the non-independent suspension directly affects the movement of the wheel on the other side, and the independent suspension cannot provide good support for lateral forces when turning and experiencing large bumps, and shock absorption is performed separately, which affects the shock absorption effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A rear coil spring structure for a vehicle suspension shock absorber, comprising a plurality of spring mounting seats rotatably connected to a torsion beam, wherein the plurality of spring mounting seats are provided between:

[0007] The buffer unit includes a rotating rod and a sliding rod rotatably connected to a plurality of spring mounting seats, the sliding rod is slidably connected to the inner wall of the rotating rod, and the outer peripheral walls of the rotating rod and the sliding rod are sleeved with a first spring, a second spring and a third spring.

[0008] Preferably, a connecting seat is fixedly connected to the outer wall of the torsion beam, and the connecting seat is rotatably connected to the spring mounting seat.

[0009] Preferably, a mounting seat is fixedly connected to the outer wall of the spring mounting seat, and the mounting seat is connected to the wheel hub.

[0012] Preferably, the first rotating seat is fixedly connected to one end of the rotating rod, and the second rotating seat is fixedly connected to one end of the sliding rod.

[0015] The utility model discloses a rear coil spring structure for automobile suspension shock absorption, which has the following beneficial effects:

[0016] The rear coil spring structure of the automobile suspension shock absorption has a structure in which, when the wheel hub on one side is slightly bumped, the spring mounting seat rotates to drive the rotating rod or the sliding rod to move. At this time, the first spring is stretched, and the second and third springs are compressed. Under the action of the first, second and third springs, the buffering effect is improved. At the same time, the wheel hub is buffered separately to avoid the force transmission between the two wheel hubs through the torsion beam being affected, resulting in the two wheel hubs interacting with each other and causing bumps on both sides. When the wheel hub experiences a larger bump, the torsion beam is twisted, and at the same time, it acts on the spring mounting seat and wheels on both sides to ensure the integrity of the vehicle and improve the vehicle's resistance to lateral forces.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The embodiment of the present application provides a rear coil spring structure for shock absorption of automobile suspension, which solves the problem that the movement of the wheel on one side of the non-independent suspension directly affects the movement of the wheel on the other side, and the independent suspension cannot provide good support for the lateral force when turning and experiencing large bumps, and each performs shock absorption separately, which affects the shock absorption effect. When the wheel hub on one side is slightly bumped, the spring mounting seat 2 rotates to drive the rotating rod 501 or the sliding rod 502 to move. At this time, the first spring 507 is stretched, and the second spring 508 and the third spring 509 are compressed. Under the action of the first spring 507, the second spring 508 and the third spring 509, the buffering effect is improved. At the same time, the wheel hub is buffered separately to avoid affecting the force transmission between the two wheel hubs through the torsion beam 1, which causes the two wheel hubs to interact with each other and cause bumps on both sides. When the wheel hub encounters large bumps, the torsion beam 1 is twisted, and at the same time, it acts on the spring mounting seat 2 and the wheels on both sides, thereby ensuring the integrity of the vehicle and improving the vehicle's resistance to lateral forces.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The embodiment of the utility model discloses a rear coil spring structure for shock absorption of an automobile suspension.

[0027] According to the attached Figure 1-4As shown, it includes multiple spring mounting seats 2 rotatably connected to the torsion beam 1, and multiple spring mounting seats 2 are provided between:

[0028] The first spring 507 is connected to the spring 508 of the second and third springs 509 of the second and third springs 509 of the third springs 509.

[0029] A connecting seat 201 is fixedly connected to the outer wall of the torsion beam 1 . The connecting seat 201 is rotatably connected to the spring mounting seat 2 . The spring mounting seat 2 is rotatably connected to the torsion beam 1 via the connecting seat 201 .

[0030] The outer wall of the spring mounting seat 2 is fixedly connected with a mounting seat 3 , which is connected to the wheel hub. The buffer unit 5 is connected to the wheel hub through the spring mounting seat 2 and the mounting seat 3 .

[0031] A shock absorber 4 is rotatably connected to the outer wall of the spring mounting seat 2 , and the shock absorber 4 is rotatably connected to the vehicle frame, so that the vehicle frame is buffered by the shock absorber 4 .

[0032] The outer wall of the spring mounting seat 2 is fixedly connected to a fixing seat 6 , and the inner wall of the fixing seat 6 is correspondingly rotatably connected to a first rotating seat 503 and a second rotating seat 504 .

[0033] The first rotating seat 503 is fixedly connected to one end of the rotating rod 501, and the second rotating seat 504 is fixedly connected to one end of the sliding rod 502. The rotating rod 501 and the sliding rod 502 are rotatably connected to the corresponding fixed seat 6 through the first rotating seat 503 and the second rotating seat 504. When the wheel hub is slightly bumped, the wheel hub drives the mounting seat 3 to move, causing the spring mounting seat 2 to rotate relative to the torsion beam 1.

[0034] The other end of the rotating rod 501 is fixedly connected to the first contact seat 505, and the other end of the sliding rod 502 is fixedly connected to the second contact seat 506. The second contact seat 506 is slidably connected to the outer peripheral wall of the rotating rod 501, and drives the fixed seat 6 to move under the rotation of the spring mounting seat 2. At this time, the fixed seat 6 drives the corresponding rotating rod 501 or sliding rod 502 to move. At this time, the sliding rod 502 slides along the inner wall of the rotating rod 501, so that the distance between the first contact seat 505 and the second contact seat 506 becomes larger.

[0035] The first contact seat 505 and the second contact seat 506 are fixedly connected to both ends of the first spring 507, the second contact seat 506 is fixedly connected to one end of the second spring 508, the other end of the second spring 508 is fixedly connected to the first rotating seat 503, the first contact seat 505 is fixedly connected to one end of the third spring 509, the other end of the third spring 509 is fixedly connected to the second rotating seat 504, when the distance between the first contact seat 505 and the second contact seat 506 becomes larger, the first spring 509 between the first contact seat 505 and the second contact seat 506 is fixedly connected to the first rotating seat 503. 07 is stretched, and at the same time, the distance between the first contact seat 505 and the second rotating seat 504 becomes smaller, and the distance between the second contact seat 506 and the first rotating seat 503 becomes smaller, compressing the second spring 508 and the third spring 509. Under the action of the first spring 507, the second spring 508 and the third spring 509, the slight bump of the wheel hub is buffered. At the same time, under the rotation of the spring mounting seat 2, the wheel hub is buffered separately to avoid the force transmission between the two wheel hubs through the torsion beam 1 being affected, resulting in the interaction between the two wheel hubs and causing bumps on both sides;

[0036] When the wheel hub experiences a large bump, the mounting seat 3 drives the spring mounting seat 2 to rotate and perform the same movement as described above. When the movement of the spring mounting seat 2 reaches its limit, the spring mounting seat 2 generates a force on the torsion beam 1. Under the limitation of the torsion beam 1, the spring mounting seat 2 is prevented from independently moving too much.

[0037] The movement of the torsion beam 1 drives the spring mounting seat 2 on the other side to move up and down, causing the wheel to move. At the same time, the torsion beam 1 is elastic. When transmitting motion, the torsion beam 1 is twisted. At this time, under the action of the torsion beam 1, the spring mounting seat 2 and the wheels on both sides are simultaneously affected, ensuring the integrity of the vehicle and improving the vehicle's resistance to lateral forces.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
