Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, an integrated leaf spring seat assembly for a heavy truck of the present invention is composed of a left leaf spring seat integrated structure, a right leaf spring seat integrated structure, and an ingot beam. Part of the integrated structure of the left leaf spring seat is used to connect with the rear ear of the maintenance-free leaf spring of the first axle, and the other part is used to connect with the front ear of the non-maintenance-free leaf spring of the second front axle.

[0028] The integrated structure of the left leaf spring seat includes a vertical plane, an inverted L-shaped structure, a cylinder 3, a bush 4, a two-way boss 5, and a casting boss 9.

[0029] The vertical plane is arranged perpendicular to the Yuanbao beam; the vertical side of the inverted L-shaped structure is parallel to the vertical plane. ...

Abstract

The invention discloses an integrated plate spring seat assembly used for a heavy truck, pertaining to the technical field of chassis components of trucks. A one-axle back plate spring seat (assembly)and a two-axle front plate spring seat (assembly) of a double front axle car model series are developed and designed in an integrated manner. A round girder structure of a traditional mold part is greatly simplified to be a groove-shaped structure. The integrated plate spring seat assembly is composed of a left-plate spring seat integration structure, a right-plate spring seat integration structure and the round girder. Stress of a car frame assembly is effectively dispersed in order to improve torsional rigidity of the overall truck. Additionally, the integrated plate spring seat assembly isconfigured for small space of a car frame. The number of assembly parts is reduced. Great input into a mold in the early phase is decreased. The integrated plate spring seat assembly is high in reliability.

Description

technical field [0001] The invention belongs to the technical field of truck chassis components, and relates to the integrated development and design of a first axle rear leaf spring support assembly and a second axle front leaf spring support of a double front axle steering truck. Background technique [0002] At present, the rear support of the front first axle and the front support of the second front axle of a domestic truck with double front axles are installed independently. When the length of the two leaf springs is 1800mm, the space between the two leaf springs is compact and it is difficult to disperse the stress of the frame assembly. It leads to early fatigue failure at the position where the frame longitudinal beam is installed with the leaf spring seat. [0003] Moreover, the existing Yuanbao beam structure is usually installed on the support of the front second bridge with bolts. The Yuanbao beam is a complex sheet metal part, which takes up a large space, whic...
