German Bosch Rexroth springs, Bosch Rexroth models, Bosch Rexroth prices

Bosch Rexroth springs are conical disc-shaped. They can be used individually or in series or parallel combinations. They bear static or dynamic axial loads at the upper inner edge and lower outer edge. Upon compression, they deform until flattened, storing energy as a live load. When necessary, they automatically convert into additional compressive load required for sealing, reducing the continuous tightening requirements for gaskets and packing. Disc springs are special springs that are conical in the axial direction and bear loads. After deforming under load, they store potential energy. When bolts loosen, the disc spring releases part of the potential energy to maintain pressure in the flange connection to meet sealing requirements. The stress distribution of disc springs decreases uniformly from the inside out, achieving high compensation force with low travel.

Bosch Rexroth spring mechanical principles

Ring springs consist of outer rings with internal conical surfaces mating with inner rings with external conical surfaces. The number of outer rings is determined by the magnitude of the load and deformation requirements. Ring springs are commonly used in applications where space is limited but strong buffering is required. A ring spring comprises many pairs of inner and outer rings. If damaged or worn, individual rings can be replaced rather than the entire assembly, making repair easier and more economical. Due to significant friction on the contact surfaces when the outer and inner rings slide relative to each other along the mating cone, the axial force during loading is balanced by surface pressure and friction. This effectively reduces the effect of the axial load, thereby increasing the spring stiffness. During unloading, friction hinders the recovery of elastic deformation, effectively reducing the spring force. The characteristic curve of a ring spring during one loading and unloading cycle is OABO. Without friction, it would be OC. During unloading, the characteristic curve switches from point B, not from point E, due to elastic hysteresis of the spring, causing a reduction. Ring spring: A spring composed of alternating stacked washer-like spring steel rings with internal conical and external cylindrical surfaces, and washer-like spring steel rings with internal cylindrical and external conical surfaces. The number of pairs of inner and outer rings in a ring spring is determined by the magnitude of the load it bears and the deformation requirements.

Bosch Rexroth spring advantages and classification

The advantages of leaf springs are simple structure, reliable operation, low cost, and easy maintenance. They serve as both the elastic element and the guiding device of the suspension. One end is hinged to the frame, allowing transmission of various forces and torques, and determining the wheel's runout trajectory. At the same time, they provide a certain degree of frictional damping. Achieving three benefits at once, they are widely used in non-independent suspensions. Leaf springs are classified by shape: 1）elliptical leaf spring; 2）semi-elliptical leaf spring; 3）quarter-elliptical leaf spring; 4）single-leaf spring. Elliptical, semi-elliptical, and quarter-elliptical leaf springs are all composite-type leaf springs, relying on friction between the leaves for high cushioning and vibration-damping performance, and are widely used in the suspension systems of automobiles, tractors, and railway vehicles; single-leaf springs consist of a single piece of spring steel and are mostly used in mechanical equipment and instruments to clamp working components.

Bosch Rexroth spring features

Suspensions using torsion bar springs are lighter in weight, have a simpler structure, and require no lubrication. By adjusting the installation angle of the fixed end of the torsion bar spring, automatic adjustment of vehicle body height is easily achieved. Torsion bar springs store greater elastic energy per unit volume and have low mass. Compared to coil springs, torsion bar springs are compact and easy to arrange. They are widely used in off-road vehicles, light passenger cars, and trucks. Torsion bar springs are classified by cross-sectional shape into circular, tubular, and flat types. Solid circular torsion bars have a simple structure and are most commonly used. For assembly, both ends are machined with splines, hexagonal, square, etc. shapes. Due to the small size of the spline ends, spline connections are mostly used. Generally, the major diameter of the spline is 1.2 to 1.3 times the working diameter of the torsion bar, and the spline length is approximately 1.4 times the spline major diameter. As long as the crushing stress of the spline teeth is within permissible limits, the spline teeth should not be excessively long. Torsion bar springs generally use involute splines according to GB3478. The JSB2705 standard recommends a standard pressure angle of 45° for splines, with modules of 1mm and 0.75mm. To facilitate assembly of torsion bar springs, some designs feature unequal diameters for the splines at both ends or machine a blind tooth on the spline teeth at both ends.
