Description

Technical Field

[0001] This invention relates to the field of double wishbone independent suspension technology, specifically a double wishbone independent suspension and a rear steering wheel device. Background Technology

[0002] The suspension is a general term for all force-transmitting connections between a car's frame (or monocoque chassis) and axles (or wheels). Its function is to transmit forces and torques acting between the wheels and the frame, and to buffer the impact forces transmitted from uneven road surfaces to the frame or body, reducing the resulting vibrations to ensure a smooth ride. A typical suspension structure consists of elastic elements, guiding mechanisms, and shock absorbers; some structures also include bump stops and stabilizer bars. The suspension is a crucial assembly in a car, elastically connecting the frame and wheels and affecting various performance characteristics. While a car suspension may appear to consist only of rods, cylinders, and springs, it is far from simple. In fact, achieving perfection in a car suspension is quite challenging because it must satisfy both the requirements of comfort and handling stability—two conflicting aspects.

[0003] Currently, when a vehicle is in motion, the wheels contact the uneven ground, causing the wheels to tilt and shift, which increases the friction between the tires and the ground, and affects the handling stability and safety of the vehicle in daily use. Summary of the Invention

[0004] The purpose of this invention is to provide a double wishbone independent suspension and a rear steering wheel device to solve the problem mentioned in the background art that when existing vehicles are driving on uneven surfaces, the wheels are subjected to bumps, causing the wheels to tilt and shift, thereby increasing the friction between the tires and the ground and affecting the handling stability and safety of daily vehicles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double wishbone independent suspension and a rear steering wheel device, comprising a double wishbone independent suspension, wherein both sides of the double wishbone independent suspension are connected to a correction frame via a movable shaft, one end of the correction frame is movably connected to one side of the rear steering wheel, and both sides of the top of the double wishbone independent suspension are provided with fixed shafts, wherein a first hydraulic tensioner is movably connected to the outer side of the rod of the fixed shaft, a telescopic spring is sleeved on the outer side of the first hydraulic tensioner, and one end of the first hydraulic tensioner is movably connected to a movable rod provided between the two correction frames.

[0006] As a preferred embodiment of the present invention, each of the correction frames is movably connected to a stabilizing frame on one side, and the stabilizing frames are movably connected to both sides of the fixed frame via movable pins. Each of the stabilizing frames is fixedly connected to a first movable hinge seat on one side, and a first electro-hydraulic rod is movably connected to one side of the first movable hinge seat. One end of the first electro-hydraulic rod is movably connected to a movable connector inside the fixed seat at the bottom of the fixed frame.

[0007] As a preferred embodiment of the present invention, a plurality of second electro-hydraulic rods are provided on one side inside the double wishbone independent suspension, and one end of the plurality of second electro-hydraulic rods is movably connected to the threaded movable pin at the top of the fixed frame through a movable pin.

[0008] As a preferred embodiment of the present invention, slots are provided on both sides of the bottom end of the double wishbone independent suspension, and an electric hydraulic cylinder is inserted and connected inside the slots. A pull rod is fixedly connected to both ends of the electric hydraulic cylinder.

[0009] As a preferred embodiment of the present invention, the bottom sides of the double wishbone independent suspension are connected to a second electro-hydraulic tensioner via movable pins, and the telescopic end of each second electro-hydraulic tensioner is movably connected to the bottom end of one of the correction frames via movable pins.

[0010] As a preferred embodiment of the present invention, the top and bottom ends of the double wishbone independent suspension are fixedly connected to a stabilizing seat.

[0011] In a preferred embodiment of the present invention, the bottom ends of the two straightening frames are connected to a fixing member by a movable connecting rod, and the top of one end of the fixing member is movably connected to the top of the straightening frame by a pin, and a connecting and stabilizing rod is provided between the two fixing members.

[0012] In a preferred embodiment of the present invention, a switch panel is provided on one side of the double wishbone independent suspension, and a first electro-hydraulic rod control switch and a second electro-hydraulic rod control switch are provided on the outer side of the switch panel. The first electro-hydraulic rod and the second electro-hydraulic rod are electrically connected to an external power source through the first electro-hydraulic rod control switch and the second electro-hydraulic rod control switch, respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1) The stabilizing frame connected by the movable pins on both sides of the fixed frame facilitates the correction and stabilization of the rear steering wheel. This causes the first electric hydraulic rods on both sides of the fixed seat to extend and retract, pulling the correction frame on the first movable hinge seat. The correction frame is pulled back to the center, which facilitates the correction and alignment of the rear steering wheel and prevents the tires on the rear steering wheel from wearing due to large angle deflection.

[0015] 2) The rear steering wheel is adjusted by the correction frame on the double wishbone independent suspension. When the angle of the two correction frames is large, the movable rod is hydraulically pulled by the first hydraulic tensioner to make the two correction frames return to the center, thereby reducing the tire wear of the rear steering wheel.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 A double wishbone independent suspension and rear steering wheel device includes a double wishbone independent suspension 1. Both sides of the double wishbone independent suspension 1 are connected to a correction frame 2 via a movable shaft. One end of the correction frame 2 is movably connected to one side of the rear steering wheel 11. Fixed shafts 21 are provided on both sides of the top of the double wishbone independent suspension 1. A first hydraulic tensioner 22 is movably connected to the outer side of the rod of the fixed shaft 21. A telescopic spring 23 is sleeved on the outer side of the first hydraulic tensioner 22. One end of the first hydraulic tensioner 22 is movably connected to a movable rod 24 provided between the two correction frames 2.

[0023] In practical use, during vehicle operation, in order to prevent the double wishbone independent suspension 1 and the wheel camber angle from changing too much and causing wear on the wheels, the rear steering wheel 11 is adjusted by the correction frames 2 on both sides of the double wishbone independent suspension 1. When the angle of the two correction frames 2 is too large, the movable rod 24 is hydraulically pulled by the first hydraulic puller 22 at the top of the double wishbone independent suspension 1, so that the two correction frames 2 are straightened, reducing the tire wear of the rear steering wheel 11.

[0024] Each straightening frame 2 is movably connected to a stabilizing frame 3 on one side. The stabilizing frames 3 are movably connected to both sides of the fixed frame 31 via movable pins. Each stabilizing frame 3 is fixedly connected to a first movable hinge seat 32 on one side. A first electric hydraulic rod 33 is movably connected to one side of the first movable hinge seat 32. One end of the first electric hydraulic rod 33 is movably connected to a movable connector inside the fixed seat 34 at the bottom of the fixed frame 31.

[0025] In practical use, when the stabilizing frame 3, which is connected to the movable pins on both sides of the fixed frame 31, is used to correct and stabilize the rear steering wheel 11, the first electric hydraulic rod 33, which is movably connected to both sides of the fixed frame 31, pulls the correction frame 2 on the first movable hinge seat 32, so that the correction frame 2 can be pulled to facilitate the correction and alignment of the rear steering wheel 11.

[0026] A number of second electro-hydraulic rods 4 are provided on one side inside the double wishbone independent suspension 1. One end of the number of second electro-hydraulic rods 4 is movably connected to the threaded movable pin 41 on the top of the fixed frame 31 through a movable pin.

[0027] In practical use, the second electric hydraulic rod 4 and the threaded movable pin 41 on the top of the fixed frame 31 can be used to limit the stabilizing frames 3 on both sides of the fixed frame 31, thereby reducing the tilt angle of the rear steering wheel 11.

[0028] The bottom of the double wishbone independent suspension 1 has slots 5 on both sides, and an electric hydraulic cylinder 51 is inserted and connected inside the slots 5. The two ends of the electric hydraulic cylinder 51 are fixedly connected to the pull rods 52.

[0029] In practical use, to prevent the steering wheel from turning at a large angle, the electric hydraulic cylinder 51 inside the slot 5 pulls the tie rod 52 to lift it, thereby reducing the tilt angle of the steering wheel.

[0030] The bottom sides of the double wishbone independent suspension 1 are connected to the second electro-hydraulic tensioners 6 by movable pins. The telescopic end of each second electro-hydraulic tensioner 6 is movably connected to the bottom end of one of the correction frames 2 by movable pins.

[0031] In practical use, the second electric hydraulic tensioner 6 can be used to pull up one side of the bottom of one of the correction frames 2 to prevent excessive deflection of the rear steering wheel 11.

[0032] The top and bottom ends of the double wishbone independent suspension 1 are fixedly connected to a stabilizing seat 7.

[0033] In practical use, the stability of the double wishbone independent suspension 1 is improved by the stabilizing seat 7 during vehicle operation, making it less likely for the rear steering wheel 11 to tilt during movement.

[0034] Two of the straightening frames 2 are connected to the bottom of a fixing member 8 by a movable connecting rod. The top of one end of the fixing member 8 is movably connected to the top of the straightening frame 2 by a pin. A connecting and stabilizing rod 81 is set between the two fixing members 8.

[0035] In practical use, the fixing parts 8 and the stabilizing rods 81 facilitate the stabilization of the alignment frame 2. A switch panel is provided on one side of the double wishbone independent suspension 1. A first electro-hydraulic rod control switch and a second electro-hydraulic rod control switch are provided on the outside of the switch panel. The first electro-hydraulic rod 33 and the second electro-hydraulic rod 4 are electrically connected to an external power source through the first electro-hydraulic rod control switch and the second electro-hydraulic rod control switch, respectively.

[0036] In practical use, the switch panel facilitates the operation of electrical appliances.
