Abstract
The utility model provides a balanced suspension for four U-bolts of a heavy truck, aiming at solving the problems that the distance between two adjacent U-bolts is further, the clamping distance of the U-bolts is also far, and the interference with other parts, such as a crossbeam and the like, happens easily in the balanced suspension for the four U-bolt of the heavy truck in the prior art. The balanced suspension comprises a balance shaft housing, spring steel plates, U-bolts and U-bolt seats, wherein the four U-bolts are assembled in a splayed shape with an upper opening; the spacing between two adjacent U-bolts is less than or equal to 52mm; and the total clamping length of the spring steel plates is less than or equal to 350mm. The balanced suspension has the benefits that the spring steel plates and the U-bolt seats are lap-jointed in a shape of a stair; the effective length of the spring steel plates is enlarged, the stress on each piece of the spring steel plates is reasonable, the service life of the spring steel plates is effectively prolonged, and both the loading capability and the flexibility of the spring steel plates are taken into account flexibly, so that the safety and the reliability of the trucks are improved.
Description
Invention field
The utility model relates to the heavy motor vehicle balance suspension, specially refers to heavy truck four-U-bolt balanced suspension.
Background technology
Prior art heavy motor vehicle balance suspension generally includes parts such as balance shaft housing, saddle clamp seat, spring plate and saddle clamp, and by balance shaft housing, saddle clamp, saddle clamp seat and nut with the fixing balance suspension that forms of spring plate.Usually, balance shaft housing is installed in the below of spring plate, spring plate successively stacks from top to bottom according to predefined quantity, its length from big to small, the saddle clamp seat is installed in the top of spring plate, and saddle clamp " is ridden and put " in the both sides of stacked spring plate and by nut balance shaft housing, spring plate and saddle clamp seat is connected and fixed.Because the bolt itself of stable equilibrium axle housing, spring plate and saddle clamp seat takes the shape of the letter U, and " rides and put " again in the both sides of stacked spring plate, therefore, this bolt is referred to as saddle clamp, and corresponding permanent seat is referred to as the saddle clamp seat.In addition, prior art has only two saddle clamp stable equilibrium axle housings, spring plate and saddle clamp seats usually in a balance suspension, and this class balance suspension is commonly called two U-bolt balanced suspensions.Two U-bolt balanced suspensions are owing to have only two support bolt stable equilibrium axle housings, spring plate and saddle clamp seat, and fixed effect is relatively poor, easily produce faults such as fixing insecure, spring plate center bolt fracture of spring plate and spring plate fracture.For strengthening the constant intensity of balance shaft housing, spring plate and saddle clamp seat, the fixing so-called four-U-bolt balanced suspension of four saddle clamps has appearred again adopting in a balance suspension.But, the distance of adjacent two saddle clamps of prior art four-U-bolt balanced suspension is bigger, generally about 55mm～60mm, the clamp distance of saddle clamp also Hen is big, reach 370mm, because structural limitations, in the spring plate swing, be easy to interfere, have hidden danger of quality and design defect with other positions such as crossbeams.
Summary of the invention
For the distance that overcomes adjacent two saddle clamps that the prior art heavy truck four-U-bolt balanced suspension exists bigger, the clamp distance of saddle clamp also Hen big easily and other position such as crossbeam problem such as interfere, the utility model proposes a kind of heavy truck four-U-bolt balanced suspension.The utility model heavy truck four-U-bolt balanced suspension comprises balance shaft housing, spring plate, saddle clamp and saddle clamp seat, four saddle clamps are the setting of " eight " font, the spacing of adjacent two saddle clamps is less than or equal to 52mm, and the total clamping length of spring plate is less than or equal to 350mm; Wherein, the total clamping length of described spring plate is meant the length of balance shaft housing spring plate contact position along the spring plate length direction, and promptly balance shaft housing is to the actual clamping length of spring plate; Described four saddle clamps are the setting of " eight " font and are meant that per 2 of 4 saddle clamps are one group, and the installation that slopes inwardly relatively from the bottom to top of two groups of bolts makes it see from the front and is " eight " font, rather than perpendicular to spring plate; The spacing of described adjacent two saddle clamps is meant the same group of spacing between the saddle clamp.
Further, the intilted relatively from the bottom to top angle of two groups of saddle clamps of the utility model four-U-bolt balanced suspension is 81.5 degree, and wherein, described intilted angle is meant saddle clamp and horizontal angle when spring plate is level attitude.
Further, the end that the utility model four-U-bolt balanced suspension balance shaft housing is installed nut is provided with spherical step, and disposes spherical pad.
Further, the bottom of the utility model four-U-bolt balanced suspension balance shaft housing is provided with the loss of weight groove.
Further, the both sides of the utility model four-U-bolt balanced suspension saddle clamp seat are provided with two draw-in grooves that saddle clamp is installed, and the bottom is provided with the loss of weight groove, and the centre is provided with the center bolt hole.
The useful technique effect of the utility model heavy truck four-U-bolt balanced suspension is that spring plate and saddle clamp seat are the stepped appearance overlap joint, spring plate effectively uses length to increase, each sheet is stressed rationally, effectively improve the service life of spring plate, accomplished that the load-carrying capacity and the spring plate flexibility of spring plate take into account, improved the safety and the reliability of vehicle operating.
