Description

Technical Field

[0001] The utility model relates to the technical field of leaf spring supports, in particular to a rear leaf spring support for a rear frame of an automobile with high stability. Background Art

[0002] As a key component in the vehicle's suspension system, the rear leaf spring support on the rear frame of an automobile fulfills the crucial task of connecting the frame and leaf springs and transmitting load. Its primary function is to stabilize the leaf spring's fixed position, reducing friction and uneven loads during its movement, thereby ensuring suspension stability and comfort during driving. With the development of the automotive industry, the load demands placed on the rear frame and leaf spring system have steadily increased. This is particularly true in high-load vehicles such as heavy trucks and commercial vehicles. Traditional rear leaf spring support structures no longer fully meet the performance requirements of modern vehicles.

[0003] At present, there are some deficiencies in the rear leaf spring supports of automobile rear frames on the market, which are specifically manifested in the following aspects:

[0004] Inflexible clamping force adjustment: Traditionally, supports often employ a fixed clamping force, making it difficult to adapt to leaf spring ends of varying thicknesses and types. While some supports incorporate adjustment mechanisms, these processes are often complex and inconvenient, making precise clamping force control difficult to achieve under varying operating conditions, reducing their adaptability and versatility.

[0005] Excessive friction: Traditional supports usually directly contact the leaf spring, which can easily lead to increased wear between the leaf spring and the support due to excessive friction, thereby affecting the smoothness of the leaf spring's movement and increasing maintenance frequency and cost.

[0006] Complex installation and difficult maintenance: Existing rear leaf spring supports usually require complex operations during installation and adjustment, and require high precision in the fit between components. Once damaged or adjusted, they often require long maintenance and high-cost replacement.

[0007] Therefore, this invention proposes a high-stability rear leaf spring support for a rear frame of an automobile to solve the above problems. Utility Model Content

[0008] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a high-stability automobile rear frame rear leaf spring support.

[0009] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a high-stability rear leaf spring support for a rear vehicle frame, comprising a fixing seat and side support arms distributed on the left and right sides of the top, an upper pressing assembly is installed between the top ends of the side support arms on both sides, a connecting cross plate is connected between the side support arms near the lower end, a bottom support assembly is slidably connected between the side support arms on both sides, a threaded through hole is provided at the center of the connecting cross plate, a jacking bolt is screwed into the internal thread of the threaded through hole, and the top end of the jacking bolt pushes the bottom support assembly upward;

[0010] The upper pressing assembly specifically includes the following structures:

[0011] A positioning pin passing through the top ends of the side support arms on both sides;

[0012] Rotate the compression sleeve sleeved on the positioning pin;

[0013] The bottom support assembly specifically includes the following structures:

[0014] A sliding support seat slidably connected between the side support arms on both sides;

[0015] Two support rollers are installed on the top of the sliding bearing.

[0016] Preferably, the ends of the leaf spring are clamped between the compression sleeve and two lower support rollers.

[0017] Preferably, guide columns are provided at the left and right ends of the bottom of the sliding support seat, and the guide columns on both sides are correspondingly slidably inserted into the inside of the guide holes provided at the left and right ends of the top of the connecting horizontal plate.

[0018] Preferably, the left and right ends of the sliding support seat are each provided with two vertically distributed side guide teeth, and the two side guide teeth on both sides are correspondingly slidably engaged with the inside of two guide rails provided on the inner side surface of the side support arm on the same side.

[0019] Preferably, the four corner ends of the fixing seat are provided with positioning holes for screws to penetrate and position.

[0020] The beneficial effects of the present invention are as follows:

[0021] Flexible Clamping Adjustment: The upper clamping assembly provides adjustable clamping force through the combination of a locating pin and a clamping sleeve. The clamping sleeve rotates freely relative to the locating pin, providing precise clamping of the upper leaf spring end. This design allows the support to accommodate leaf spring ends of varying sizes and thicknesses, meeting diverse usage requirements and enhancing product versatility and adaptability.

[0022] Reduced friction, increased service life: The bottom support assembly effectively reduces friction between the leaf spring and the support via support rollers. During the leaf spring's movement, the support rollers provide smooth support, reducing wear and extending the service life of the support and leaf spring system.

[0023] Precise adjustment and positioning: The push-in bolt in the threaded hole can be moved up and down by rotation, accurately controlling the clamping force of the leaf spring. This design ensures precise clamping and adjustable tightening force regardless of the thickness of the leaf spring, further enhancing the adaptability of the support.

[0024] Reliable Sliding Support Design: The sliding support base utilizes guide posts and guide holes to ensure exceptional stability and precision during the upward and downward sliding motion of the support assembly. Side guide teeth, combined with guide rails, ensure the stability of the sliding support base, preventing deflection or wobble. This design enhances the reliability and durability of the entire support, ensuring stable operation under high-load and dynamic conditions.

[0025] Simplified installation and maintenance: Using conventional fixing methods such as screws and positioning holes, this support is easy to install and can be quickly disassembled and maintained when needed. Its simple and strong structure provides stable support, greatly reducing maintenance costs and complexity.

[0026] In summary, the high-stability rear leaf spring support for automobile rear frames of this utility model, through structural optimization and precision design, effectively improves the support's stability, service life, and adaptability. The adjustable function of the clamping assembly, the friction reduction function of the support assembly, and the precise guidance design of the sliding support seat not only enhance the overall reliability of the leaf spring system but also ensure smooth operation over long-term use. These innovative designs work together to improve the performance of the rear leaf spring system of automobile rear frames while reducing maintenance complexity and costs, thus possessing high market application value.
