Abstract
The present invention passes through a kind of car double rear axle leaf spring, including each single reed, blind hole is provided with the two sides center of each single reed, provided with positioning finger setting in correspondence blind hole, reed group top and bottom after combination are respectively provided with clamping plate one and clamping plate two, and clamping plate one and clamping plate two are fastened as a whole in the side of reed group by screw bolt and nut；Friction plate is additionally provided between the contact surface of each single reed.The mode that is connected of the present invention, reduces leaf spring in vehicle running, the probability that steel plate spring assembly center is broken caused by bolt looseness；Each single reed is positioned by positioning pin member, not only ensure that installation is easy to connect, in vehicle operation, each single reed does not also misplace, and ensures each single reed formation collective effect power of steel plate spring assembly, the reliability of steel plate spring assembly has been effectively ensured.
Description
Technical field
The present invention relates to the leaf spring of auto parts and components, specifically a kind of car double rear axle leaf spring.
Background technology
Each monolithic connected mode of car double rear axle leaf spring is at present:Each single reed drill centers（Through hole）, then each single reed be fastenedly connected by centre bolt, nut.
Fig. 1 is the assembling front view of double Rear Axle Steel Plate springs at present.
1 is bolt in figure, and 2 be nut, and 3,4,5 be reed, 3rd, it is additionally provided with friction plate 11 between 4,5 reeds, friction plate 11, which is played, reduces the frictional force between each reed, while also reducing noise, such a mechanism reed 3,4,5 in vehicle running is fastenedly connected by bolt 1 with nut 2.Leaf spring is in vehicle running, and central hole has stress concentration, when the U bolt of fastening steel plate spring loosens, central hole easy fracture.
The content of the invention
The present invention is in order that double Rear Axle Steel Plate springs slacken center stress concentration in vehicle running, and raising leaf spring service life, spy proposes a kind of car double rear axle leaf spring.
Therefore, the technical scheme is that：A kind of car double rear axle leaf spring, including each single reed, blind hole is provided with the two sides center of each single reed, provided with positioning finger setting in correspondence blind hole, reed group top and bottom after combination are respectively provided with clamping plate one and clamping plate two, and clamping plate one and clamping plate two are fastened as a whole in the side of reed group by screw bolt and nut.
Further improve is：Friction plate is additionally provided between the contact surface of each single reed.
Beneficial effect：
The mode that is connected of the present invention, reduces leaf spring in vehicle running, the probability that steel plate spring assembly center is broken caused by bolt looseness.
Each single reed is positioned by positioning pin member, not only ensure that installation is easy to connect, in vehicle operation, each single reed does not also misplace, and ensures each single reed formation collective effect power of steel plate spring assembly, the reliability of steel plate spring assembly has been effectively ensured.
This automobile can be applied to various few pieces with double Rear Axle Steel Plate spring structures（Variable cross-section）Leaf spring, mounting structure can effectively reduce each reed center working stress, improve leaf spring service life.
Brief description of the drawings
Fig. 1 is the front view of former double Rear Axle Steel Plate springs.
Fig. 2 is the front view of the present invention.
Fig. 3 is along A-A amplification views in Fig. 2.
1 is bolt in figure, and 2 be nut, and 3,4,5 be reed, and 6,7,8 be single reed, and 9 be clamping plate one, and 10 be clamping plate two, and 11 be friction plate, and 12 be blind hole, and 13 be alignment pin.
Embodiment
This automobile is with double Rear Axle Steel Plate springs as shown in Fig. 2, Fig. 3：
A kind of car double rear axle leaf spring, including each single reed 6,7,8, blind hole 12 is provided with the two sides center of each single reed 6,7,8, positioned in correspondence blind hole 12 provided with alignment pin 13, reed group (each single reed is reed group altogether) top and bottom after combination are respectively provided with clamping plate 1 and clamping plate 2 10, and clamping plate 1 and clamping plate 2 10 are fastened as a whole in the side of reed group by bolt 1 and nut 2.
Friction plate 11 is additionally provided between the contact surface of each single reed 6,7,8.
Claims (2)
1. a kind of car double rear axle leaf spring, including each single reed, it is characterised in that：It is provided with the two sides center of each single reed in blind hole, correspondence blind hole provided with positioning finger setting, the reed group top and bottom after combination are respectively provided with clamping plate one and clamping plate two, and clamping plate one and clamping plate two are fastened as a whole in the side of reed group by screw bolt and nut.
