Description
Technical field
The utility model is related to a kind of leaf spring, more particularly to a kind of steel plate spring connecting device.
Background technology
Leaf spring is most widely used a kind of elastic element in full-sized car suspension, if it is wide by dry plate but not
It is isometric（Thickness can be equal, can not also be equal）The spring beam of an approximately equi-strength that is composed of alloy spring piece,
Its effect is that the form that vehicle frame is hung with vehicle bridge links together, exposed between vehicle frame and vehicle bridge, bears wheel to vehicle
The load impacting of frame cuts down the high vibration of vehicle body, keeps the stationarity of vehicle traveling and the adaptability to different road conditions.
Usually in the design of vehicle, as shown in Figure 1, leaf spring 2 is between vehicle frame and rear axle 6, by being placed on
The fixed plate 11 of 6 lower section of rear axle and a pair of of U-bolt 8 coordinate, and so that it is pressed abd fixed on the rear axle of car body 6, when using U-shaped
When leaf spring 2 is fixed in bolt 8, one end that U-bolt 8 is open is extended downwardly along the upper end of leaf spring 2, simultaneously
Across fixed plate 11, U-bolt 8 is pierced by one end of fixed plate 11 by nut tightening, after making leaf spring 2 and car body
Bridge 6 is fixed.
Full-sized car, since road conditions are bad, can pitch during transport, and leaf spring 2 is for bearing vehicle
The load impacting to vehicle frame is taken turns to cut down vehicle body high vibration, therefore when leaf spring 2 is fixed, is needed more high-strength
Spend connector, and U-bolt 8 is an entirety, length is longer to cause intensity relatively low, so as to cause leaf spring and rear axle it
Between bonding strength it is relatively low, security performance is bad.
Utility model content
The purpose of this utility model is to provide a kind of steel plate spring connecting device, its advantage is that improving leaf spring with after
Bonding strength between bridge, to ensure that the safety of vehicle.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of leaf spring connection
Device is arranged between leaf spring and rear axle, and the attachment device includes more connectors and is fixed on the steel plate

The utility model is further arranged to：The four corners of the fixed plate respectively symmetrically offer connecting hole, the company
Fitting includes second bolt isometric for four across the connecting hole and for being tightened with will with second bolt
The nut clamped between the leaf spring and the rear axle.
Through the above technical solutions, the second bolt to be each passed through to the connecting hole of upper and lower two fixed plate, while running through cushion block,
So that it is more stablized, the lower end of the second bolt is connected to finally by nut thread, makes the leaf spring quilt between two fixed plates
It is fixed.
Leaf spring is fixed by using four isometric the second bolts and nut, reduces the second bolt
Connection length, to improve its intensity.
The utility model is further arranged to：The leaf spring is arc-shaped by polylith, generous consistent, different in size bullet
Property steel disc composition, be sequentially placed from long to short, from top to bottom between the elastic steel sheet.
Through the above technical solutions, when pitching during full-sized car is advanced, larger impact force is will produce,
Make wheel that rear axle be driven to move upwards, it, can stress change when leaf spring and vehicle frame conflict to make leaf spring move up
Shape simultaneously does stretching routine, at this point, leaf spring can be born from wheel to the load impacting of vehicle frame to cut down acutely shaking for vehicle body
It is dynamic, to make vehicle keep more smoothly travelling.
The utility model is further arranged to：Direction on the leaf spring along its length is equidistantly equipped with multiple for inciting somebody to action
The elastic steel sheet is clamped fixed locking assembly.
Through the above technical solutions, the setting of multiple elastic steel sheets, more preferable to the effect of car body damping, between elastic steel sheet
It is locked together by locking assembly.
The utility model is further arranged to：The locking assembly includes locking member and passes through the locking member thus will
The first bolt that the elastic steel sheet is fixed.
Through the above technical solutions, by the way that locking member is socketed in elastic rod on piece, and the first bolt is made to pass through locking member,
To make to be locked between elastic steel sheet.
The utility model is further arranged to：The locking member includes level board and affixed with the level board both ends
Vertical plate.
Through the above technical solutions, when being locked to leaf spring using locking assembly, by the level board of locking member
It being against on the steel disc of leaf spring lower end, vertical plate stretches out the upper end of leaf spring, and two vertical plates are passed through by the first bolt, from
And it will be locked between steel disc.
The utility model is further arranged to：The lower section of the leaf spring is equipped with adjusting bracket, and the adjusting bracket is equipped with
The fixed block that the leaf spring is supported.
Through the above technical solutions, for paving leaf spring, leaf spring and adjusting bracket is made to be separated by a distance, when
When full-sized car pitches during advancing, larger impact force is will produce, makes wheel that rear axle be driven to move upwards, works as steel
When flat spring and vehicle frame contradict, can stress deformation simultaneously do stretching routine, the setting of fixed block, be also used for preventing leaf spring by
Power stretch when with phase mutual friction between adjusting bracket and cause to wear.
The utility model is further arranged to：The adjusting bracket is arc-shaped by polylith, generous consistent, different in size elasticity
Steel disc forms, and is sequentially placed from long to short, from top to bottom between the elastic steel sheet, the spring steel plate of the adjusting bracket upper end
Both ends are equipped with the grasswort for being connect with car body.
Through the above technical solutions, adjusting bracket is connected by grasswort with car body, run up and down during automobile is advanced
When winnowing with a dustpan, larger impact force is will produce, make wheel, rear axle and is moved up and down together with the fixed adjusting bracket of rear axle, adjusting bracket
Setting, the form for vehicle frame to be hung with vehicle bridge links together.
In conclusion the utility model has the advantages that：
