Description
Technical Field
The utility model belongs to the technical field of heavy truck, concretely relates to balanced suspension system's of heavy truck leaf spring apron location structure.
Background
At present, the balance suspension of a commercial heavy truck is matched with a plate spring, and the mode that no positioning or a positioning pin positioning mode is adopted between the plate spring and a cover plate is widely adopted.
When the mechanism is not designed to be positioned, the cover plate is assembled with the few leaf springs, the cover plate is placed at the centering position of the leaf springs by visual inspection of an assembler, and then the cover plate is connected and fastened by U-shaped bolts. When the positioning pin is arranged in the mechanism, the positioning pin is used for positioning the cover plate on the assembling surface of the few-leaf spring, and then the cover plate is connected and fastened by the U-shaped bolt. When no positioning design is carried out, the cover plate is placed at the centering position of the few leaf springs by visual inspection of an assembler, the cover plate is staggered relative to the leaf springs, the U-shaped bolts are assembled asymmetrically, the stress is not uniform in the working process, and parts are easy to damage.
When the positioning pin is adopted for positioning, positioning holes need to be drilled on the few leaf springs, and for the few leaf springs, the leaf springs bear the load of the whole vehicle, the leaf springs are the leaf springs with larger stress, and the stress concentration can be generated at the positioning holes after the holes are drilled, so that the risk of breakage of the leaf springs at the positions is greatly increased.
The cover plate is of a cuboid structure and collides with the inner side of the support, so that the rotation angle is limited, the requirement cannot be met, and abnormal stress is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a leaf spring apron location structure of balanced suspension system of heavy truck, the technical problem that solve is: realize few leaf spring and apron accurate positioning and harmless to spare part.
In order to solve the technical problem, the utility model provides a leaf spring apron positioner for balanced suspension system of heavy truck, its characterized in that: the device comprises a plate spring, a balance suspension bracket, a U-shaped bolt, a positioning gasket and a cover plate; a plurality of plate reeds of the plate spring are assembled through a central bolt and a positioning gasket, and a plate spring seat is rotatably connected with a balanced suspension bracket through a bearing; the plate spring is arranged in a groove at the upper part of the plate spring seat, the cover plate is horizontally arranged on the upper surface of the plate spring, and a positioning hole is formed in the center of the contact surface of the cover plate 5 and the plate spring and corresponds to the position of a central bolt and a positioning gasket on the plate spring; two groups of U-shaped bolts are sleeved at two ends of the plate spring seat and the plate spring, and the upper ends of the two groups of U-shaped bolts penetrate through the cover plate to be fixed.
Has the advantages that: the utility model discloses with the gasket design of former leaf spring center bolt for can playing locate function's gasket, when the former center bolt gasket effect of performance, make it play with the effect of apron location. The cover plate and the few leaf springs are accurately positioned, assembled and used, and parts are uniformly stressed. Positioning holes do not need to be drilled on the few-leaf springs, so that the use reliability and the service life of the few-leaf springs are improved.

Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.
The utility model provides a pair of balanced suspension system's of heavy truck leaf spring apron location structure, its characterized in that: the device comprises a plate spring 1, a balanced suspension bracket 2, a U-shaped bolt 3, a positioning gasket 4, a cover plate 5 and a plate spring seat;
the plate spring is a few of leaf springs and is formed by assembling 5 leaf springs below through a central bolt, the balance suspension bracket 2 is fixedly connected with the frame longitudinal beam,
the plate spring seat is rotationally connected with the balanced suspension bracket through a bearing;
the plate spring 1 is arranged in a groove in the upper portion of the plate spring seat, the cover plate 5 is horizontally placed on the upper surface of the few-leaf spring, two groups of U-shaped bolts are sleeved at two ends of the plate spring seat and the plate spring, and the upper ends of the two groups of U-shaped bolts penetrate through the cover plate 5 to be fixed.
A positioning hole is formed in the center of the contact surface of the cover plate 5 and the plate spring and corresponds to the position of the central bolt positioning gasket 4 on the plate spring; the positioning size of the positioning hole corresponds to that of the plate spring positioning gasket, and small clearance fit is adopted.
Arc-shaped grooves are formed in the lower portions of the two sides of the cover plate 5, so that interference with the inner side of the balanced suspension bracket is avoided, and the requirement of the rotation angle is met.
In the balanced suspension system (fig. 1), when a plate spring is connected with a cover plate 5 through a U-shaped bolt 3, the cover plate 5 is positioned by a central bolt positioning gasket 4 on the plate spring and then is assembled and fastened.
The gasket of the central bolt of the plate spring (figure 2) is designed into a gasket with a positioning function, the thickness is thickened so as to facilitate positioning, and the outer diameter and the cover plate positioning hole are designed into small clearance fit.
A positioning hole is designed at one end of the contact surface of the cover plate (figure 3) and the plate spring, the positioning size of the positioning hole corresponds to that of a plate spring positioning gasket, and small clearance fit is adopted.
The utility model discloses can make apron and few leaf spring accurate positioning assembly use, the spare part atress is even. Positioning holes do not need to be drilled on the few-leaf springs, so that the use reliability and the service life of the few-leaf springs are improved.
