The front camber angle is determined based on the vehicle's dead weight and load capacity, and generally does not require adjustment. The front suspension of the T815-2 car is a torsion bar spring and a hydraulic cylinder shock absorber. Due to part and installation errors, as well as fatigue deformation of the torsion bar, it will cause changes in the camber angle of the front wheel. Therefore, it is necessary to adjust it as appropriate. Torsion bar spring T815-2 The bar spring of a car is a torsion bar with a length of 1900 mm and a diameter of 56 mm. It has a circular section and trapezoidal splines at both ends. The torsion bar material is 45CrNiMoV-A advanced alloy spring steel, after machining, multiple pre-twist, heat treatment, surface treatment and other processes, and finally outsourcing epoxy resin and antirust paint processing. After the above treatment, the metal fiber structure inside the torsion bar material generates left-to-right or elastic deformation to reserve elasticity. During installation, the front end of the torsion bar is connected with the torsion bar swing arm spline, and the front end of the swing arm is suspended from the front half sleeve by a double-hole hanging ear, and the rear end of the tie bar is fixed to the frame by a spline. When the car is driving, when the current wheel bounces upwards, the impact force passes through the front axle sleeve → hangers → torsion bar arms, thereby twisting the torsion bar and pre-storing the elasticity through the torsion bar to prevent the wheels from jumping upwards. This process will increase the impact force and twist of the wheel. The elasticity of the rods balances and thus acts as a damping effect. It should be pointed out that due to the directionality of the pre-twist in the manufacturing process of the torsion bar, the directionality of the torsion bar is determined, and the torsion bar spring can only play a damping effect when the wheel is jumping upwards, so the torsion bar spring should be reduced. Use with a resonator. T815-2 Front-wheel camber adjustment of all cars The structure of the front suspension of all T815-2 cars is similar to that of the principle, but different model adjustment data are different. The following is a description of T815-2SV2. It is not difficult to see from the figure that the front suspension of the T815-2 car shows that with other parameters already determined, the camber angle of the front wheels depends only on the value of “hâ€. For the T815-2SVS2 model, the specified front camber angle is 3°30′±40′, and the corresponding “h†value is 322mm. We can adjust the “h†value to adjust the front camber angle. The steps are as follows: (1) Fix the car and remove the hanger; (2) Adjust the half shaft so that the "h" value is 322mm; (3) Measure the value of "a" and choose different specifications of the hanger according to the a value: a value range / mm No. 106～1222122～1383138～1544154～1705 The center distances of hangers 2, 3, 4 and 5 are respectively 112mm, 128mm, 144mm and 160mm. If the measured a value is not in this range, the torsion bar should be turned in the corresponding direction. Turn one tooth. (4) After the assembly is completed, put down the axle and move the car to the distance of one wheel. Measure the camber angle of the front wheel. If it is not correct, it must be readjusted. After correct, you can adjust the other wheel. The difference between the values ​​cannot be greater than 8mm. In practical applications, the front wheel introversion caused by the torsion bar fatigue deformation tends to break the torsion bar due to a large load, resulting in losses. Therefore, timely adjustment is particularly important. Deep Drawing,Metal Deep Drawing,Deep Drawn Part Sheet Metal Fabrication Co., Ltd. , http://www.challmetal.com
