Automobile rear suspension leaf spring pressing block

Abstract

This utility model discloses a rear suspension leaf spring pressure block for automobiles, relating to the technical field of automotive parts. It includes a pressure block body with a weight-reducing groove. The pressure block body has symmetrical mounting holes for U-bolts on both ends, and a fixing hole for fastening bolts at the center of the weight-reducing groove. This application, through the "+" shaped weight-reducing groove on the pressure block body, compared to traditional solid structures or single-direction grooves, can reduce the overall weight of the pressure block to the greatest extent, reducing the load on the rear suspension system and preventing the leaf spring from accelerating fatigue due to excessive load. Simultaneously, the symmetrically arranged reinforcing plates on both sides of the longitudinal groove and the symmetrically arranged reinforcing plates on both sides of the transverse groove can specifically reinforce the structural strength of the groove area, preventing deformation of the pressure block under stress and ensuring that the pressure block can still stably bear the load transmitted by the leaf spring while reducing weight, thus balancing lightweight design and structural reliability.

Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, specifically to a rear suspension leaf spring pressure block for automobiles. Background Technology

[0002] The rear suspension leaf spring is one of the core components of the vehicle chassis system. It plays a crucial role in transmitting vehicle body load, buffering road impact vibrations, and maintaining vehicle driving stability. The leaf spring compression block, as an important fixing component of the leaf spring, directly affects the working stability and service life of the leaf spring, as well as the operating efficiency of the entire rear suspension system and the overall vehicle performance. In the current technological field, traditional automotive rear suspension leaf spring pressure blocks generally suffer from the following technical defects: To ensure structural strength, traditional pressure blocks mostly adopt a solid block structure, resulting in a large weight. This design not only significantly increases the long-term load on the leaf springs, accelerating fatigue damage and shortening their service life, but also increases the overall weight of the rear suspension system, increasing energy consumption during vehicle operation, and adversely affecting vehicle handling agility and ride comfort. Summary of the Invention

[0003] The purpose of this utility model is to provide a rear suspension leaf spring pressure block for automobiles to overcome the above-mentioned defects in the prior art.

[0004] A rear suspension leaf spring pressure block for automobiles includes a pressure block body, the pressure block body is provided with a weight reduction groove, the two sides of both ends of the pressure block body are symmetrically provided with mounting holes for installing U-bolts, and the pressure block body is provided with a fixing hole for installing fastening bolts at the center of the weight reduction groove.

[0005] Preferably, the weight-reducing groove includes a longitudinal groove and a lateral groove. The longitudinal groove is arranged along the length direction of the main body of the pressing block, and the lateral groove is arranged along the width direction of the main body of the pressing block and intersects with the longitudinal groove to form a cross-shaped structure.

[0006] Preferably, the elongated groove and the wide groove have the same width.

[0007] Preferably, reinforcing plates are symmetrically provided on both sides of the elongated groove.

[0008] Preferably, reinforcing plates are symmetrically provided on both sides of the wide groove.

[0009] Preferably, the pressure block body is provided with a pad at the top of each mounting hole.

[0010] Preferably, the pad is provided with a groove for engaging with a U-bolt.

[0011] The beneficial effects achieved by this utility model are as follows: This application utilizes a cross-shaped weight-reducing groove on the main body of the pressure block. Compared to traditional solid structures or single-direction grooves, this design can significantly reduce the overall weight of the pressure block, thereby reducing the load on the rear suspension system and preventing the leaf springs from fatigued due to excessive load. Simultaneously, the symmetrical reinforcement plates on both sides of the longitudinal groove and the symmetrical reinforcement plates on both sides of the lateral groove can specifically reinforce the structural strength of the groove area, preventing the pressure block from deforming under stress. This ensures that the pressure block can stably withstand the load transmitted by the leaf spring while reducing its weight, thus balancing lightweight design and structural reliability.

[0019] like Figure 1-3 As shown, this utility model provides a rear suspension leaf spring pressure block for automobiles, including a pressure block body 1. The pressure block body 1 is provided with a weight reduction groove 2, which includes a longitudinal groove 21 and a lateral groove 22. The longitudinal groove 21 is arranged along the length direction of the pressure block body 1, and the lateral groove 22 is arranged along the width direction of the pressure block body 1 and intersects with the longitudinal groove 21 to form a cross-shaped structure. This structure can be adapted to the shape of the pressure block body 1. While effectively reducing weight, the cross structure disperses stress, improves the overall rigidity and deformation resistance of the pressure block body 1, and ensures that the pressure block is not easily damaged when bearing the force of the leaf spring. In addition, the elongated groove 21 and the wide groove 22 have the same width. The consistent width can make the stress distribution around the elongated groove 21 and the wide groove 22 more uniform, avoid local stress concentration caused by different groove widths, and further improve the stability and service life of the pressure block structure. However, the two sides of the pressure block body 1 are symmetrically provided with mounting holes 5 for installing U-bolts. The pressure block body 1 is provided with a fixing hole 6 for installing fastening bolts at the center of the weight reduction groove 2. The pressure block body 1 is provided with a pad 7 on the top of each mounting hole 5. The pad 7 is provided with a groove 71 that mates with the U-bolt. The pad 7 can increase the contact area between the U-bolt and the top of the mounting hole 5 of the pressure block body 1, reduce the pressure on the top of the mounting hole 5 when the bolt is tightened, avoid deformation or damage to the mounting hole 5 due to excessive local pressure, and extend the service life of the mounting hole 5. In addition, reinforcing plates 3 are symmetrically provided on both sides of the elongated groove 21. The reinforcing plates 3 can specifically compensate for the local structural strength loss caused by the elongated groove 21, enhance the load-bearing capacity of the main body 1 in the length direction, and the symmetrical arrangement can make the forces on both sides of the elongated groove 21 balanced, avoid the longitudinal force generated when the leaf spring is working, which will cause the edge of the elongated groove 21 to crack or deform, and ensure the structural integrity and load-bearing capacity of the pressure block in the length direction. In addition, the wide groove 22 is symmetrically provided with reinforcing plates 4 on both sides. The reinforcing plates 4 can effectively supplement the structural strength of the wide groove 22 and prevent the wide groove 22 from being damaged due to the lateral force of the leaf spring or the installation stress. The symmetrical layout can ensure that the force on both sides of the wide groove 22 is uniform, improve the deformation resistance of the pressure block body 1 in the width direction, and avoid the pressure block from affecting the normal operation of the rear suspension system due to the weakness of the structure in the width direction.

[0020] Detailed implementation methods and principles: During installation, the pressure block body 1 of the leaf spring is placed in the preset installation position of the rear suspension leaf spring of the car, so that the contact surface of the pressure block body 1 and the leaf spring are completely in contact, ensuring that the subsequent fixing structure can accurately correspond to the stress point of the leaf spring. Using the fixing hole 6 opened in the center of the weight reduction groove 2 of the pressure block body 1, the fastening bolt is inserted into the fixing hole 6 and pre-connected with the corresponding installation position of the suspension system. Through the initial tightening of the fastening bolt, the pressure block body 1 is pre-positioned on the leaf spring, avoiding the displacement of the pressure block body 1 during the subsequent assembly process. Then, align the two ends of the U-bolt with the mounting holes 5 symmetrically arranged on both sides of the pressure block body 1. Since each mounting hole 5 is provided with a pad 7 at the top, and the pad 7 has a groove 71 that mates with the U-bolt, the shank of the U-bolt is precisely matched with the groove 71 of the pad 7. The groove 71 limits the U-bolt, and both ends of the U-bolt completely pass through the mounting hole 5 to form a ring-shaped fixing base for the leaf spring. Then, tighten the nuts of the fastening bolts and U-bolts in sequence. First, tighten the fastening bolts in the fixing hole 6 to further improve the fit between the pressure block body 1 and the leaf spring and enhance the positioning effect. Then, tighten the nuts of the U-bolts. The tightening force of the U-bolts will firmly press the pressure block body 1 onto the leaf spring. At this time, the pad 7 increases the contact area between the U-bolt and the pressure block body 1, and avoids wear around the mounting hole 5 due to excessive local pressure. During vehicle operation, the rear suspension leaf spring vibrates and deforms due to road impacts. The pressure block body 1, through the circumferential tightening force of the U-bolt and the positioning force of the fastening bolt in the fixing hole 6, jointly restricts the excessive displacement of the leaf spring, ensuring that the leaf spring always moves within the preset working range and maintaining the stability of the suspension system. At the same time, the weight reduction groove 2 on the pressure block body 1 reduces the overall weight of the pressure block and the load on the suspension system, while preventing the pressure block from increasing the load on the leaf spring due to excessive weight.

[0021] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
