Description

Technical Field

[0001] This invention relates to the field of automotive suspension system technology, specifically to a rear suspension arrangement structure for a rear-axle, rear-wheel-drive vehicle. Background Technology

[0002] The suspension is a system of tires, tire air, springs, and shock absorbers, along with the linkages that connect the vehicle to the wheels and allow relative movement between them. The suspension system must simultaneously support ride quality and handling / holding. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The role of a car's suspension is to maximize friction between the tires and the road surface, provide good handling and steering stability, and enhance passenger comfort.

[0003] In existing rear-axle, rear-wheel-drive vehicles, the rear suspension uses shock absorbers to dampen vibrations and cushion impacts. When driving on bumpy roads, the shock absorbers effectively absorb shocks, making the ride more comfortable. However, rear-axle, rear-wheel-drive vehicles only have two shock absorbers for this purpose. When the vehicle is driven continuously for extended periods, these two shock absorbers gradually fatigue, and the performance of their internal elastic elements, damping devices, and other key components deteriorates. This results in increasingly poor damping, allowing more of the fine vibrations and impacts that were previously effectively filtered out to be transmitted into the passenger compartment, severely impacting passenger comfort and reducing the overall driving experience. Summary of the Invention

[0004] The purpose of this invention is to provide a rear suspension arrangement structure for a rear-axle, rear-wheel-drive automobile to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The support mechanism is located on both sides of the fixed frame. The support mechanism includes lower arms located on both sides of the fixed frame. A connecting sleeve is fixedly installed at one end of the lower arm. Two fixing ears are fixedly installed on the side of the drive axle. The support mechanism is used to support the device.

[0008] The shock absorption mechanism is located on both sides of the fixed frame. The shock absorption mechanism includes shock absorbers located on both sides of the fixed frame, and elastic elements are installed on the shock absorbers. The shock absorption mechanism is used to absorb shocks in automobiles.

[0009] Preferably, a fixing rod is fixedly installed on the inner wall of the upper end of the fixing frame, and two fixing columns are fixedly installed on the bottom surface of the fixing rod. The lower end of the fixing column is fixedly connected to the bottom surface of the two fixing ears by bolts.

[0010] Preferably, two support bars are fixedly installed on the inner wall of the fixing frame, and the other side of the two support bars is fixedly connected to the side of two fixing ears by bolts. Two mounting brackets are fixedly installed on the top surface of the fixing frame.

[0011] Preferably, two connecting blocks are fixedly installed on the sides of the two mounting brackets, and upper arms are hinged to the sides of the multiple connecting blocks, with connectors fixedly installed at the other ends of the multiple upper arms.

[0012] Preferably, the inner wall of the connector is hinged with a connecting arm, two connecting slots are opened on both sides of the fixing frame, and multiple connecting sleeves are provided on the lower arm and the connecting sleeve. The sides of the multiple connecting sleeves are respectively hinged to the inner wall of the multiple connecting slots.

[0013] Preferably, a caliper is provided on one side of the rotating disk, and the other ends of multiple lower arms are respectively hinged to the other ends of two connecting arms. A through hole is provided on the side of the connecting arm, and the inner wall of the through hole is rotatably connected to the outer wall of the drive half shaft through a bearing seat.

[0014] Preferably, there are two shock absorbers and two elastic elements, and a fixing frame is fixedly installed on the side of the lower arm, with the inner wall of the fixing frame hinged to the lower end of the shock absorber.

[0015] Preferably, an L-shaped plate is fixedly installed on the side of the lower arm, and an arc-shaped groove is opened through the side of the L-shaped plate. A limit strip is fixedly installed on the lower side of the shock absorber. The outer wall of the limit strip is slidably connected to the inner wall of the arc-shaped groove. An arc-shaped rod is slidably installed through the side of the limit strip, and the two ends of the arc-shaped rod are fixedly connected to the inner wall of the arc-shaped groove.

[0016] Preferably, a fixing block is fixedly installed on the side of the lower arm, and a groove is opened on the top surface of the fixing block. A second hinge block is slidably installed on the inner wall of the groove, and a support rod is hinged to the inner wall of the second hinge block. A first hinge block is fixedly installed on the upper side of the shock absorber, and the outer wall of the first hinge block is hinged to the other end of the support rod.

[0017] Preferably, a sliding rod is slidably installed through both sides of the hinge block, and the two ends of the sliding rod are fixedly connected to the inner walls of both sides of the groove. An elastic element 2 is slidably installed on the outer wall of the sliding rod, and the two ends of the elastic element 2 are fixedly connected to the two sides of the hinge block and the inner wall of one side of the groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention uses a shock absorber and an elastic element to dampen and buffer the vehicle's shocks. A limiting strip, an arc-shaped groove, and an arc-shaped rod limit the shock absorber's movement, ensuring greater stability as it rotates to dampen the vehicle. When the shock absorber rotates to a certain angle, a hinge block moves a support rod, which in turn moves a second hinge block. The second hinge block then compresses the second elastic element, which further dampens the device. This dual damping effect ensures greater stability during prolonged continuous driving, preventing a decrease in damping performance and thus guaranteeing passenger comfort and improving the overall driving experience.

[0020] The drive axle is supported and fixed by the fixed rods and fixed columns, making the drive axle connection more stable. At the same time, the support bars further support and fix the drive axle, ensuring that the drive axle drives the drive half shaft more stably when it drives the steering axle, thus improving the stability of the device. The upper arm, connecting arm and lower arm further support the device, making it more stable. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-8 As shown, this application provides a rear suspension arrangement structure for a rear-wheel drive vehicle, including: a fixed frame 1, a drive axle 101 fixedly mounted on one side of the fixed frame 1, drive half-shafts 102 mounted on both ends of the drive axle 101 via steering axles, rotating disks 103 mounted on both ends of the two drive half-shafts 102 respectively, and wheel hubs 104 mounted on the sides of the rotating disks 103, and further including:

[0036] Support mechanism 2 is provided on both sides of fixed frame 1. Support mechanism 2 includes lower arm 211 located on both sides of fixed frame 1. A connecting sleeve 212 is fixedly installed at one end of lower arm 211. Two fixing ears 202 are fixedly installed on the side of drive axle 101. Support mechanism 2 is used to support the device.

[0037] Specifically, such as Figures 1-8 As shown, a fixing rod 201 is fixedly installed on the inner wall of the upper end of the fixing frame 1. Two fixing columns 203 are fixedly installed on the bottom surface of the fixing rod 201. The lower end of the fixing column 203 is fixedly connected to the bottom surface of the two fixing ears 202 by bolts.

[0038] In this embodiment: the fixing rod 201 is fixed by the fixing frame 1, the fixing rod 201 is fixed to the fixing column 203, and the fixing column 203 supports and fixes the fixing ear 202 and the drive axle 101.

[0039] Specifically, such as Figures 1-8 As shown, two support bars 204 are fixedly installed on the inner wall of the fixed frame 1. The other side of the two support bars 204 is fixedly connected to the side of two fixing ears 202 by bolts. Two mounting brackets 205 are fixedly installed on the top surface of the fixed frame 1.

[0040] In this embodiment, the fixed ear 202 and the drive axle 101 are further supported and fixed by the support bar 204.

[0041] Specifically, such as Figures 1-8 As shown, two connecting blocks 206 are fixedly installed on the sides of the two mounting brackets 205 respectively, and upper arms 207 are hinged to the sides of the multiple connecting blocks 206 respectively. Connectors 208 are fixedly installed on the other end of the multiple upper arms 207.

[0042] In this embodiment: the upper arm 207 is connected by the mounting bracket 205, and the upper arm 207 is fixed to the connector 208.

[0043] Specifically, such as Figures 1-8 As shown, the inner wall of the connector 208 is hinged with a connecting arm 209, and two connecting slots 210 are respectively opened on both sides of the fixing frame 1. Multiple lower arms 211 and connecting sleeves 212 are provided, and the sides of multiple connecting sleeves 212 are respectively hinged to the inner walls of multiple connecting slots 210.

[0044] In this embodiment: the connecting sleeve 212 and the lower arm 211 are connected by the connecting groove 210, and the lower arm 211 is further connected to and installed on the connecting arm 209.

[0045] Specifically, such as Figures 1-8 As shown, a caliper 213 is provided on one side of the rotating disk 103, and the other ends of multiple lower arms 211 are respectively hinged to the other ends of two connecting arms 209. A through hole is provided on the side of the connecting arm 209, and the inner wall of the through hole is rotatably connected to the outer wall of the drive half shaft 102 through a bearing seat.

[0046] In this embodiment, the drive half-shaft 102 is supported by the connecting arm 209, making the drive half-shaft 102 more stable.

[0047] The shock absorption mechanism 3 is disposed on both sides of the fixed frame 1. The shock absorption mechanism 3 includes shock absorbers 302 located on both sides of the fixed frame 1. An elastic element 303 is installed on the shock absorber 302. The shock absorption mechanism 3 is used to absorb shocks in the car.

[0048] Specifically, such as Figures 1-8 As shown, there are two shock absorbers 302 and two elastic elements 303. A fixing frame 301 is fixedly installed on the side of the lower arm 211, and the inner wall of the fixing frame 301 is hinged to the lower end of the shock absorber 302.

[0049] In this embodiment, the device is damped and buffered by the shock absorber 302 and the elastic element 303.

[0050] Specifically, such as Figures 1-8 As shown, an L-shaped plate 304 is fixedly installed on the side of the lower arm 211. An arc-shaped groove 305 is opened through the side of the L-shaped plate 304. A limit strip 306 is fixedly installed on the lower side of the shock absorber 302. The outer wall of the limit strip 306 is slidably connected to the inner wall of the arc-shaped groove 305. An arc-shaped rod 307 is slidably installed through the side of the limit strip 306. The two ends of the arc-shaped rod 307 are fixedly connected to the inner wall of the arc-shaped groove 305.

[0051] In this embodiment: the limiting strip 306 is limited by the arc-shaped groove 305, and the limiting strip 306 is further limited by the arc-shaped rod 307, thereby limiting the shock absorber 302 and making the rotation of the shock absorber 302 more stable.

[0052] Specifically, such as Figures 1-8 As shown, a fixing block 311 is fixedly installed on the side of the lower arm 211. A groove 312 is opened on the top surface of the fixing block 311. A second hinge block 310 is slidably installed on the inner wall of the groove 312. A support rod 309 is hinged to the inner wall of the second hinge block 310. A first hinge block 308 is fixedly installed on the upper side of the shock absorber 302. The outer wall of the first hinge block 308 is hinged to the other end of the support rod 309.

[0053] In this embodiment: the groove 312 limits the movement of the second hinge block 310, making the movement of the second hinge block 310 more stable. When the shock absorber 302 rotates at a certain angle, it drives the first hinge block 308 and the support rod 309 to move, thus driving the first hinge block 308 to move.

[0054] Specifically, such as Figures 1-8 As shown, a sliding rod 313 is slidably installed through the side of the hinge block 310. The two ends of the sliding rod 313 are fixedly connected to the inner walls of both sides of the groove 312. An elastic element 314 is slidably installed on the outer wall of the sliding rod 313. The two ends of the elastic element 314 are fixedly connected to the side of the hinge block 310 and the inner wall of one side of the groove 312.

[0055] In this embodiment: the sliding rod 313 further limits the hinge block 310, and at the same time limits the elastic element 314. The setting of the elastic element 314 applies elastic force to the hinge block 310, thereby providing shock absorption and buffering for the hinge block 310.

[0056] Specifically, this solution works as follows: When the vehicle is in motion, the shock absorber 302 and elastic element 303 dampen the vehicle's shocks. Simultaneously, the limiting strip 306, arc-shaped groove 305, and arc-shaped rod 307 limit the movement of the shock absorber 302. As the shock absorber 302 rotates slowly to a certain angle, its rotation becomes more stable. When the shock absorber 302 rotates to a certain angle, the hinge block 308 moves the support rod 309, which in turn moves the hinge block 310. The hinge block 310 then compresses the elastic element 314, which further dampens the device. Under this dual damping effect... When the vehicle is driven continuously for a long time, the effect of dual shock absorption is more stable and less prone to decline, thus ensuring the comfort of passengers and improving the overall driving quality. The drive axle 101 is supported and fixed by the fixed rod 201 and fixed column 203, making the connection of the drive axle 101 more stable. At the same time, the support bar 204 further supports and fixes the drive axle 101, ensuring that the drive axle 101 drives the drive half shaft 102 more stably through the steering axle, improving the stability of the device. The upper arm 207, connecting arm 209 and lower arm 211 further support the device, making the device more stable.

[0058] This invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
