German brema springs brema models brema prices

brema springs, as elastic elements, are widely used in the suspensions of modern automobiles, including sedans, trucks, and off-road vehicles. Compared with leaf springs, torsion bar springs offer a series of advantages: high energy storage per unit mass, which reduces vehicle weight and saves material; since the torsion bar spring is fixed to the frame, it reduces unsprung mass, improving ride smoothness; when applied to the front suspension of front-wheel-drive vehicles, the torsion bar spring can be arranged longitudinally, leaving space for the oscillating half-shafts of the front drive axle. However, torsion bar manufacturing costs are relatively high, with strict requirements for materials and processes. In addition, torsion bar springs serve only as elastic elements and require a guiding mechanism. Torsion bar springs are made of chrome-vanadium alloy spring steel, with a very smooth surface after machining. The surface of the torsion bar must be well protected during use; typically, a layer of epoxy resin is applied to the surface of the torsion bar spring, wrapped with a layer of fiberglass cloth, coated with another layer of epoxy resin, and finally coated with asphalt and anti-rust paint to prevent collision, scratching, and corrosion, thereby extending the service life of the torsion bar spring.

brema spring installation and removal

Hydraulic hand pallet trucks are widely used in production. During maintenance of their pressure oil pumps, we found that the pressure spring responsible for returning the piston rod of the pressure oil pump and the pressure arm of the truck has a wire diameter of n and stores an elastic force of up to 1000N, making its installation and removal very difficult. This often delays fault elimination and directly affects production progress. Several measures were taken, but none were effective. Therefore, I designed a pressure spring installer/remover as shown in Figure 1. The installer/remover consists of a lower pressure lever 1, pressure blocks 10, connecting pins 14, nuts 1, spherical washers 12, upper pressure lever 13, positioning sleeves 16, and levers. During operation, rotate the nut 11 to an appropriate position so that the cylindrical head claw of the lower pressure lever 1 contacts the vehicle body 2, with two pressure blocks 10 symmetrically pressing on the washer 6. Rotate the compression nut n; through the tension rod 15, the upper pressure lever 13 and lower pressure lever 1 move relative to each other, forcing the pressure spring to compress. When the washer 6 leaves the cylindrical pin 7, the pressure wheel shaft 9, pressure wheel 8, and cylindrical pin 7 can be removed. At this point, loosen the nut 11, remove the installer/remover, take off the pressure spring, and proceed with disassembly, inspection, and maintenance of the pressure oil pump. The positioning sleeve 16 on the installer/remover is a key component; during manufacturing, one end has an internal spherical surface with a slot-shaped hole in the middle, and the other end has an inclined flat surface, forming an interference fit with the pressure lever. It is required to have good contact with the spherical washer 12 and the ball head of the lever 15. The pressure block 10 and connecting pin 14 have a clearance fit, requiring flexible rotation. The connecting pin 14 and upper pressure lever 13 have an interference fit. The connecting shaft 18 and pressure lever have a clearance fit.

brema spring features

1) Precise adjustment performance, i.e., the relationship between force and displacement is highly sensitive; 2) Good flexibility, i.e., a relatively wide deformation range; 3) Relatively easy manufacturing; 4) Compact structure; 5) High energy utilization rate. Example characteristics: Conical helical springs offer good buffering performance and can withstand large loads. Volute helical springs can store more energy and withstand larger loads, but the manufacturing process is more complex. The performance of concave helical springs is similar to that of conical helical springs, and they are mostly used in cushions and mattresses. Spring wire cross-sections include circular and rectangular shapes, with circular cross-sections being the most common. Helical springs, also known as torsion springs, are springs that withstand torsional deformation, with their working part tightly wound into a helical shape. The end structure of torsion springs is processed into various shapes of torsion arms rather than hooks or loops. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in industrial production such as automobiles, machine tools, and electrical appliances.

brema spring features and applications

Features: Compared with ordinary compression or extension springs, their elastic force is very constant, outputting a nearly linear elastic force, ensuring that the product does not change due to variations in elastic force during use. In narrow and elongated spaces, they can minimize space usage, enhancing possibilities for aesthetic product design. Constant force spring applications: Lift fans, LCD monitors, sliding windows and doors, supermarket automatic checkout counters, motor carbon brush clamping devices, cables, stapler springs, power tools, car ashtrays, locomotive carbon brush accessories, medical instruments, mobile phone holders, etc.
