Abstract
The utility model relates to an off-highway dump truck flat spring slide plate chair, which is characterized in that a chair body is a frame type structure, lower circular arc surfaces (1) which are raised downwards are arranged on two ends of the lower surface of an upper plane of the chair body, a plane is arranged in the middle, and upper circular arc surfaces (9) which are raised upwards are arranged on the upper surface of a lower plane of the chair body. The flat spring slide plate chair overcomes the problem which is generated by an existing engineering car flat spring slide plate chair that the longest flat spring is easily ruptured due to unreasonable structure, and the flat spring slide plate chair not only can reduce shock on three longest pieces of the flat spring under the off-highway working conditions, but also reduces the pressure and enables the lower surface to be wear-resisting, thereby prolonging the service life of the flat spring.
Description
Technical field
The utility model relates to a kind of non-highway dumping car leaf spring slide plate chair, and characteristics are leaf spring slide plate chairs of a kind of tower structure.
Background technology
Traditional engineering is with in the car rear suspension, and the leaf spring slide plate chair has dual mode, and a kind of be tower structure, can be the plane but go up the plane from spacing in balance suspension, when back axle is beated, and does not have oil groove with arc surface at present; Another kind is a reaping hook formula structure, and last plane is the plane, can not be from spacing when middle back axle is beated.Because in non-highway operating mode, the vehicle ' road surface is the engineering sidewalk, railways and mineies are poor, it is big to cheat recessed out-of-flat, the axle tramp amount is big and frequent, two kinds of structures of traditional like this leaf spring slide plate chair are used and the plane can be occurred on the spring block jump under vehicle bridge and contact with the leaf spring line when spacing and be hit when non-highway operating mode, the leaf spring increase that is stressed, lower plane does not have oil groove simultaneously, cause the longest 3 of leaf spring like this, with leaf spring slide plate chair wearing and tearing, be hit above below, lengthy motion picture uses in the building site and is easy to fracture.
Summary of the invention
The purpose of this utility model provides a kind of leaf spring slide plate chair, it overcomes in the lengthy motion picture leaf spring that causes with the engineering vehicle panel spring slide plate chair unreasonable structure problem of fracture easily, tightly under non-highway operating mode, can not make to reduce above the longest 3 of leaf spring and impact, reduce pressure and following wear-resisting, thereby prolong the leaf spring life-span.
The technical solution of the utility model is: design a kind of leaf spring slide plate chair, it is characterized in that: its pedestal is a tower structure, and the lower surface two ends on plane are the following arc surfaces to lower convexity on the pedestal, and the centre is the plane; The upper surface of pedestal lower plane is the last arc surface that raises up.
On the last arc surface of described pedestal lower plane oil canal and oil groove are arranged, oil canal and oil groove are communicated with.
Maximum space on the described pedestal between the upper surface of the lower surface on plane and lower plane distance deducts the leaf spring gross thickness and interspaces apart from being 18mm.
The beneficial effects of the utility model are: this leaf spring slide plate pedestal is a tower structure, and the lower surface two ends on plane are the arcwall faces to lower convexity on the pedestal, and the centre is the plane; The upper surface of pedestal lower plane is the arc surface that raises up.On the last arc surface of pedestal lower plane oil canal and oil groove are arranged, oil canal and oil groove are communicated with, and import to oil groove leaf spring is lubricated so that grease is injected oil canal, reduce wear, and improve the leaf spring life-span.After the plane added two sections arc surfaces on the leaf spring slide plate chair, when non-highway operating mode axle tramp, being stressed above the longest 3 of leaf spring reduced, and impulsive force reduces, and prolongs more than the leaf spring life-span twice.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the example structure front view;
Fig. 2 is the example structure left view;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the site plan of embodiment when jumping on vehicle bridge;
Fig. 5 is the site plan of embodiment when jumping under vehicle bridge.
Among the figure: 1, following arc surface; 2, logical oil groove; 3, oil duct; Plane contact place on the leaf spring when 4, jumping on the vehicle bridge; Leaf spring lower plane contact position when 5, jumping on the vehicle bridge; Leaf spring lower plane contact position when 6, jumping under the vehicle bridge; Plane contact place on the leaf spring when 7, jumping under the vehicle bridge; 8, leaf spring; 9, go up arc surface.
The specific embodiment
Embodiment such as Fig. 1, Fig. 2, shown in Figure 3, this new-type leaf spring slide plate chair, seat material uses wear-resistant cast steel parts, and pedestal is a tower structure, and the lower surface two ends on plane are to be the plane in the middle of the arcwall face of lower convexity on the pedestal; Arc surface 1 under shown in Fig. 1.The upper surface of pedestal lower plane is the arc surface that raises up, and goes up arc surface 9 shown in Fig. 1.Simultaneously the maximum space vertical distance between the upper surface of the lower surface on plane and lower plane deducts the longest 3 gross thickness of leaf spring and interspaces apart from being 18mm on the control desk spring abutment body.
Oil canal 2 and oil groove 3 are arranged on the last arc surface of pedestal lower plane, and oil canal 2 and oil groove 3 is communicated with, and imports to oil groove 3 leaf spring 8 is lubricated so that grease is injected oil canal 2, reduces wear, and improves 8 life-spans of leaf spring.
Embodiment as shown in Figure 4, when jumping on vehicle bridge, the leaf spring slide plate chair can be from spacing, leaf spring lower plane contact position 5 all is a circular arc when jumping on plane contact place 4, the vehicle bridge on the leaf spring when jumping on the vehicle bridge, reduce like this and impact, reduce leaf spring 8 pressures, improve 8 life-spans of leaf spring.
Embodiment as shown in Figure 5, when jumping under vehicle bridge, the leaf spring slide plate chair equally can be from spacing, when jumping under leaf spring lower plane contact position 6 and the vehicle bridge when jumping under the vehicle bridge on the leaf spring plane contact place 7 all be circular arc, the same minimizing impacted, and reduces leaf spring 8 pressures, improves 8 life-spans of leaf spring.
Claims (3)
1, a kind of leaf spring slide plate chair, it is characterized in that: its pedestal is a tower structure, and the lower surface two ends on plane are the following arc surfaces (1) to lower convexity on the pedestal, and the centre is the plane; The upper surface of pedestal lower plane is the last arc surface (9) that raises up.
2, a kind of leaf spring slide plate chair according to claim 1 is characterized in that: oil canal (2) and oil groove (3) are arranged on the last arc surface (9) of described pedestal lower plane, and oil canal (2) and oil groove (3) are communicated with.
3, a kind of leaf spring slide plate chair according to claim 1 is characterized in that: maximum space on the described pedestal between the upper surface of the lower surface on plane and lower plane distance deducts the leaf spring gross thickness and interspaces apart from being 18mm.
