Description
Technical Field
The utility model relates to an auto-parts, concretely relates to butterfly piece formula car stabilizer bar.
Background
The stabilizer bar is an auxiliary elastic element in the automobile suspension. It is used to prevent the vehicle body from generating excessive transverse rolling when turning. Thereby preventing the vehicle from tipping laterally and improving the ride comfort. When the vehicle body only moves vertically and the suspensions on the two sides deform equally, the suspensions on the two sides move up and down simultaneously, the stabilizer bar rotates freely in the sleeve, and the stabilizer bar does not work. When the vehicle turns, because the force born by the outer suspension is large, the two-side suspension is deformed unequally, the vehicle body inclines transversely to the road surface, one side of the vehicle frame moves close to the spring support, the end of the side of the stabilizer bar moves upwards relative to the vehicle frame, the other side of the vehicle frame is far away from the spring support, the end of the corresponding stabilizer bar moves downwards relative to the vehicle frame, however, when the vehicle body and the vehicle frame incline, the middle part of the stabilizer bar has no relative movement to the vehicle frame. Thus, when the vehicle body is tilted, the longitudinal portions of both sides of the stabilizer bar are deflected in different directions, and the stabilizer bar is twisted. The torsional internal moment generated by the resilient stabilizer bar interferes with the deformation of the suspension spring, thus reducing the lateral tilt and lateral angular vibration of the vehicle body, thereby improving the vehicle running stability.
At present, two types of stabilizer bars exist in the market, one type is a conventional transverse stabilizer bar, and the other type is an improved transverse stabilizer bar which also plays a role of a thrust rod, and is called a torsion bar spring for short. Because conventional stabilizer bar just plays when the car turns, at the transverse direction, the stabilizer bar does not play a role, consequently at the transverse direction, does not need very big intensity, but the manufacturing process of stabilizer bar at present usually designs the stabilizer bar for cylindrical, just so leads to on the one hand in the material waste of transverse direction, on the other hand when the installation stabilizer bar space take up greatly, causes the installation difficulty. The transverse stabilizer bar also used as a thrust rod, which is called a sheet torsion bar spring for short, is a novel transverse stabilizer bar structure consisting of two variable cross-section plate springs and a torsion bar spring. When the automobile turns and runs, the straight torsion part of the sheet torsion bar spring is twisted, so that the transverse stabilizer bar is used, and when the automobile runs (or brakes), the plate springs on the two sides transmit the longitudinal force and the moment of the automobile, so that the wheels are ensured to move according to a set track, and the longitudinal thrust bar of the automobile is used. Compared with the traditional transverse stabilizer bar, the leaf torsion bar spring has the advantages of simple and compact structure, light weight of the suspension and low production cost. However, the flat torsion spring has the disadvantages that the plate springs on the two sides and the middle straight rod part need to be connected into a whole by welding, and the plate springs on the two sides and the straight rod part are mostly made of two materials, so that the welding difficulty is high, the cost is high, the strength is poor, and when the heat treatment is carried out after the welding, the coefficients of expansion with heat and contraction with cold of the two materials are inconsistent, cracks are easy to occur, thereby generating fatigue sources and affecting the service life.
