Embodiment Construction

[0018] Below the present invention is further described:

[0019] see Figure 1-3 ,

[0020] The invention discloses a novel leaf spring limit block, which includes a leaf spring assembly 1 and a vehicle frame 2. A front bracket 3 and a rear bracket 4 are arranged on the front wall of the vehicle frame 2. The leaf spring assembly 1 The two ends of the bottom main spring are connected to the front bracket 3 and the rear bracket 4 respectively, and the two ends of the top auxiliary spring of the leaf spring assembly 1 are respectively connected with a front movement limiter 5 and a rear movement limiter 6, so The rear of the vehicle frame 2 is respectively provided with a front moving limit block guide rail 9 and a rear moving limit block guide rail 13, both of which are hollow square structures with front and rear openings, and the vehicle frame 2 is provided with a front guide hole 17 And the rear guide hole 18, the front guide hole 17 and the rear guide hole 18 are arranged...

Abstract

The invention relates to the technical field of steel plate spring assemblies, in particular to a novel plate spring limiting block which comprises a plate spring assembly and a frame, wherein a front support and a rear support are arranged on the front wall of the frame, and the two ends of a bottom main spring of the plate spring assembly are connected with the front support and the rear support respectively. The two ends of an auxiliary spring on the top of the plate spring assembly are connected with a front moving limiting block and a rear moving limiting block respectively, a front moving limiting block guide rail and a rear moving limiting block guide rail are arranged on the rear portion of the frame respectively and are of hollow square structures with the front end and the rear end open, and a front guide hole and a rear guide hole are formed in the frame. The front guide hole and the rear guide hole are formed in the front end openings of the front moving limiting block guide rail and the rear moving limiting block guide rail. When the plate springs move upwards, the rigidity between the plate springs cannot be increased, what is ensured is that the offset frequency of the whole vehicle cannot be changed, and the comfort requirement is met.

Description

technical field [0001] The invention relates to the technical field of leaf spring assemblies, in particular to a novel leaf spring limiting block. Background technique [0002] In the suspension, the leaf spring is often used as a guide mechanism, which can simplify its structure, facilitate maintenance and reduce manufacturing costs. [0003] When a truck is in use, the load on the rear axle varies in a large range. When some models are fully loaded, the rear suspension load can even reach more than 4 times the full load. If a suspension with linear elastic characteristics is adopted and the stiffness of the leaf spring remains unchanged, the bias frequency of the rear suspension will vary greatly between full load and no load. If the stiffness of the leaf spring is designed with no-load weight, the bearing capacity of the leaf spring is not enough at full load; if the stiffness of the leaf spring is designed with the weight of full load, the stiffness of the leaf spring ...
