Description

Technical Field

[0001] This utility model relates to the field of vehicle axle technology, specifically to a vehicle axle with load-bearing steering function. Background Technology

[0002] The axle (also known as the vehicle frame) is connected to the chassis (or monocoque body) via the suspension, and wheels are mounted at both ends of it. The axle's function is to bear the load of the vehicle and maintain its normal movement on the road. Depending on the drive system, axles are classified into four types: steering axles, drive axles, steering-drive axles, and support axles. Steering axles and support axles are both driven axles. Most cars use a front-engine, rear-wheel-drive (FR) configuration, so the front axle acts as the steering axle and the rear axle as the drive axle; while in front-engine, front-wheel-drive (FF) cars, the front axle becomes the steering-drive axle, and the rear axle acts as the support axle.

[0003] In the process of realizing this utility model, the inventors discovered that:

[0004] Currently, most full trailers and semi-trailers on the market are front-drive and front-steering. The trailer is towed and steered by the tractor. All the axles on the trailer are support axles, which only serve to support the trailer body. When the vehicle turns, the axles on the trailer cannot turn. It can only turn by relying on the different steering angles of the wheels on both sides under the steering pull of the tractor. The friction resistance between the trailer wheels and the ground increases, resulting in increased wear on the wheels and the road surface. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, this utility model proposes a vehicle axle with load-bearing steering function.

[0006] Therefore, the technical solution of this utility model is as follows: an axle with load-bearing steering function, including a main beam, with both ends of the main beam curved upwards, and C-shaped seats fixedly installed at both ends of the curved main beam. A fixed shaft is fixedly installed in the middle of the C-shaped seat, and a fixed seat that rotates around the fixed shaft is sleeved on the fixed shaft. One side of the C-shaped seat is open, and one end of the fixed seat extends out of the C-shaped seat through the opening. Fixed plates are fixedly installed at the outer ends of the C-shaped seat away from the main beam. Hinges are fixedly installed on the fixed plates in the front and rear directions of the C-shaped seat and on the main beam. Hydraulic rods are installed on the hinges at the corresponding positions of the fixed plates and the main beam.

[0007] Furthermore, a convex sleeve is fixedly installed at the middle position of the front side of the fixing plate at both ends of the main beam. The fixing plate inside the convex sleeve has a hole, and a fixing sleeve passes through the hole. A wheel fixing plate is fitted on the convex sleeve. The wheel fixing plate is fixedly installed with the fixing sleeve. A limit plate is fixedly installed on the fixing plate corresponding to the rear end position of the fixing sleeve. A drum brake disc is installed between the outer side of the wheel fixing disc and the front side of the fixing plate. The drum brake disc is fixed with the wheel fixing disc. The wheel fixing disc and the drum brake disc are used for wheel installation and drum brake installation.

[0008] Furthermore, a fixing frame is fixedly installed at both ends of the main beam, and a steel leaf spring is installed above the fixing frame. A pressure plate is installed on the top of the steel leaf spring, and the pressure plate is fixed to the fixing frame by multiple fastening bolts; this provides shock absorption support for the axle and the frame. The steel leaf spring is a common shock absorber for the rear axle of trucks and is suitable for use on the axles of full trailers or semi-trailers.

[0009] Furthermore, an auxiliary beam is also provided on the main beam. Fixing buckles are fixedly installed at both ends of the auxiliary beam on the main beam. The two ends of the auxiliary beam are fixed to the fixing buckles at the corresponding positions. A diagonal brace is also fixed in the middle of the auxiliary beam. The bottom end of the diagonal brace is fixed to the main beam at the corresponding position. The auxiliary beam presses on the pressure plate at the same time. The auxiliary beam increases the structural strength of the main beam, especially increasing the structural stability of the upturned ends.

[0010] Furthermore, a dustproof curtain is installed at the opening position on the C-shaped seat, and the dustproof curtain has an opening corresponding to the position of the fixed seat, through which the fixed seat passes. The dustproof curtain prevents dust and sand from entering the C-shaped seat and affecting the rotation of the fixed seat around the fixed axis. Given the different positions of the fixed seat during rotation, in order to ensure the dustproof curtain's consistent dustproof effect, the dustproof curtain needs to have the characteristics of expansion and contraction. Using a corrugated rubber sleeve can effectively prevent dust while not hindering the rotation of the fixed seat.

[0011] Furthermore, load-bearing bearings are installed on both the upper and lower sides of the fixed seat on the outer side of the fixed shaft, and the fixed seat and the C-shaped seat are supported by the load-bearing bearings; the load-bearing bearings can reduce the frictional resistance and frictional noise between the fixed seat and the C-shaped seat when the fixed seat rotates.

[0012] Furthermore, the outer periphery of the convex sleeve is provided with multiple equally spaced roller grooves, and each roller groove is equipped with a roller, which makes rolling contact with the wheel fixing disc; the roller can reduce the frictional resistance between the convex sleeve and the wheel fixing disc.

[0013] Furthermore, the inner side of the convex sleeve and the outer side of the corresponding fixed sleeve are provided with corresponding ball grooves. Multiple balls are installed in the ball grooves, and the balls roll in contact with the convex sleeve and the fixed sleeve. The balls reduce the frictional resistance between the convex sleeve and the fixed sleeve. At the same time, with the ball grooves provided, retainers can be set between the balls to maintain the equal spacing between the balls. When the ball grooves are full, retainers are not required.

[0014] Beneficial effects: This utility model fixes the wheel mounting base to the main beam using a C-shaped seat hinged to the mounting base, and uses a hydraulic rod to drive the mounting base to rotate around the three fixed axes of the C-shaped seat, thus achieving rotational function; by adding an auxiliary beam to the main beam, the upward-curving ends of the main beam are structurally reinforced, improving the structural strength of the main beam; by using a dustproof curtain to shield the open parts of the C-shaped seat and the mounting base, dust and sand can be prevented from entering, thus ensuring smooth rotation of the mounting base; by setting ball bearings and rollers inside and outside the cam sleeve, the rotational frictional resistance between the cam sleeve and the vehicle mounting plate and the mounting sleeve is reduced, thereby improving the smoothness of wheel rotation and reducing frictional noise.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.

[0023] This utility model is as follows Figures 1 to 6 As shown:

[0024] A vehicle axle with load-bearing steering function includes a main beam 1, with both ends of the main beam 1 being upturned. C-shaped seats 2 are fixedly installed at both ends of the upturned main beam 1. A fixed shaft 3 is fixedly installed in the middle of the C-shaped seats 2. A fixed seat 4 that rotates around the fixed shaft 3 is fitted on the fixed shaft 3. One side of the C-shaped seats 2 is open, and one end of the fixed seat 4 extends out of the C-shaped seats 2 through the opening. Fixed discs 5 are fixedly installed at the outer ends of the C-shaped seats 2 at both ends of the main beam 1 away from the main beam 1. A protrusion 7 is fixedly installed at the middle position of the front side of the fixed disc 5. A hole is opened on the fixed disc 5 inside the protrusion 7, and a fixed sleeve 6 passes through the hole. A wheel fixing disc 8 is fitted on the protrusion 7. The wheel fixing disc 8 is fixedly installed between the fixed sleeve 6 and the fixed disc 5. A limit plate 10 is fixedly installed on the fixed disc 5 at the rear end position of the fixed sleeve 6. A drum brake disc 9 is installed between the outer side of the wheel fixing disc 8 and the front side of the fixed disc 5. The drum brake disc 9 is fixed to the wheel fixing disc 8.

[0025] Hinged seats 18 are fixedly installed on the fixed plate 5 in the front and rear directions of the C-shaped seat 2 and on the main beam 1. Hydraulic rods 17 are installed on the hinged seats 18 at the corresponding positions of the fixed plate 5 and the main beam 1. Fixed frames 22 are fixedly installed on the main beam 1 at the middle position near both ends. A steel leaf spring 24 is set above the fixed frame 22. A pressure plate 23 is set on the top of the steel leaf spring 24. The pressure plate 23 is fixed to the fixed frame 22 by multiple fastening bolts 25.

[0026] The wheels are fixed to the wheel mounting disc 8. The brakes are drum brakes, which are installed inside the drum brake disc 9. The drum brakes are fixed to the mounting disc 5. When braking, the brake pads rub against the drum brake disc 9 to restrict the rotation of the wheel mounting disc 8. The main beam 1 is fixed to the frame at the position of the leaf spring 24. The leaf spring 24 provides shock absorption. When turning, the hydraulic rods 17 on both sides of the C-shaped seat 2 can be extended or retracted according to the direction of steering.

[0027] When turning left, the hydraulic rod 17 on the front side of the C-shaped seat 2 extends and the hydraulic rod 17 on the rear side retracts. Utilizing the hinged connection between the fixed seat 4 and the C-shaped seat 2 via the fixed shaft 3, the fixed plate 5 rotates to the left around the fixed shaft 3, thus achieving left turn. When turning right, the hydraulic rod 17 on the front side retracts and the hydraulic rod 17 on the rear side extends, causing the fixed plate 5 to rotate to the right, thus achieving right turn. This gives the trailer an autonomous steering function, thereby reducing the frictional resistance of the wheels on the road surface during steering.

[0028] In this embodiment, an auxiliary beam 19 is also provided on the main beam 1. Fixing buckles 20 are fixedly installed on both ends of the auxiliary beam 19 on the main beam 1. The two ends of the auxiliary beam 19 are fixed to the fixing buckles 20 at the corresponding positions. A diagonal brace 21 is also fixed in the middle of the auxiliary beam 19. The bottom end of the diagonal brace 21 is fixed to the main beam 1 at the corresponding position. The auxiliary beam 19 is pressed on the pressure plate 23 at the same time.

[0029] Because the two ends of the main beam 1 curve upwards, they will bend and deform further upwards when under load. The auxiliary beam 19 can increase the structural strength of the two ends of the main beam 1 and reduce the deformation.

[0030] In this embodiment, a dustproof curtain 16 is installed at the opening position on the C-shaped seat 2. The dustproof curtain 16 has an opening corresponding to the position of the fixing seat 4. The fixing seat 4 passes through the opening. The dustproof curtain 16 is a corrugated rubber sleeve.

[0031] Due to the connection and rotation requirements of the fixed seat 4, a large part of the opening on the C-shaped seat 2 is open, which can easily lead to foreign objects such as dust and sand entering the C-shaped seat 2 and affecting the rotation of the fixed seat 4. Therefore, a dust curtain 16 is installed to block foreign objects such as dust and sand.

[0032] In this embodiment, load-bearing bearings 15 are installed on both the upper and lower sides of the fixing seat 4 on the outer side of the fixing shaft 3, and the fixing seat 4 and the C-shaped seat 2 are supported by the load-bearing bearings 15.

[0033] Since the C-shaped seat 2 is fixed, while the fixed seat 4 rotates when turning, and due to the fixed structure of the fixed seat 4 and the C-shaped seat 2, there is unavoidable friction between the upper and lower surfaces of the fixed seat 4 and the C-shaped seat 2. This friction will cause mutual wear between the fixed seat 4 and the C-shaped seat 2, as well as turning friction noise. By setting the load-bearing bearing 15, the friction resistance and noise can be reduced, and the rotation of the fixed seat 4 can be made smoother.

[0034] In this embodiment, the outer periphery of the convex sleeve 7 is provided with a plurality of equally spaced roller grooves 12, and each roller groove 12 is installed in a roller 11. The roller 11 rolls in contact with the wheel fixing disc 8. The inner side of the convex sleeve 7 and the outer side of the corresponding fixing sleeve 6 are provided with corresponding ball grooves 13. A plurality of balls 14 are installed in the ball grooves 13. The balls 14 roll in contact with the convex sleeve 7 and the fixing sleeve 6.

[0035] The wheel fixing disc 8 is fixed to the fixing sleeve 6, and the wheel fixing disc 8 rotates. Therefore, rollers 11 and balls 14 are provided as contact supports between the convex sleeve 7 and the wheel fixing disc 8 and the fixing sleeve 6, which can reduce the frictional resistance and frictional noise when the wheel fixing disc 8 and the fixing sleeve 6 rotate, so that the wheel rotates smoothly.

[0036] Any aspects not described in detail in this specification are techniques well-known in the art.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
