Problems solved by technology

[0005] In the current automobile suspension device, the torsion bar spring is generally installed on the front suspension device of the automobile, and the front and rear elastic elements are independent, independent of each other, and have no connection. If the vibration direction of the front and rear wheels of the automobile is opposite , the impact on the car will increase, and the body will move forward and backward. In addition, when the four wheels are not on the same plane or a pair of corner wheels are under a large force, the frame and body frame will be subject to certain Therefore, the existing suspension structure exists, the elastic elements are easily damaged, the frame and the body frame are easily deformed, and at the same time, it will also cause damage to the cargo or make the occupants feel uncomfortable.

Embodiment 1

[0025] As shown in Figure 1, the upper end of the front torsion bar spring 3 is connected to the control arm 1 of the front suspension of the car, the control arm of the front suspension is connected to the wheel 2, and the lower end of the rear torsion bar spring 11 is connected to the control arm 12 of the rear suspension. Link to each other, the lower end of the front torsion bar spring of the left side and the right side and the upper end of the rear torsion bar spring are equipped with gears 7,8 respectively, and two pairs of gears on the above-mentioned same side front and rear torsion bar springs mesh with each other. The upper ends of the two reset torsion bar springs 5 ​​are fixedly connected with the vehicle frame 4, and the lower ends are equipped with a reset gear 10, which meshes with the gear 8 on the rear torsion bar spring on the same side. Rod spring links to each other with vehicle frame by front torsion bar spring bearing seat 6, rear torsion bar spring beari...

Embodiment 2

[0029] On the basis of the structure of Embodiment 1, in order to prevent the gears meshing with each other from being polluted by various impurities and affecting their service life, as shown in Figure 2, three gears meshing with each other on the same side are placed in the gearbox 14, on the one hand Change the working conditions of the gears, on the other hand, after the gear box 14 is fixed on the vehicle frame 4, the three torsion bar springs on the same side can ensure the mutual meshing of the three gears through the positioning of the gear box, and save three gears. on the bearing housing. Simultaneously in order to make front and rear torsion bar spring recover deformation rapidly after torsion deformation, two resetting torsion bar springs are installed, i.e. front resetting torsion bar spring 5-1 and rear resetting torsion bar spring 5-2.

Embodiment 3

[0031] On the basis of the structure of Embodiment 2, when the control arms of the front and rear suspensions are double-wishbone structures, as shown in Figures 3 and 4, the upper ends of the front torsion bar springs 3 on the left and right sides are installed on the front suspensions on the left and right sides. On the upper cross arm 1-1 of the frame control arm 1, the lower ends of the rear torsion bar springs 11 on the left and right sides are installed on the upper end cross arms of the rear suspension control arms 12 on the left and right sides, and the reset torsion bar spring 5 consists of two The front return torsion bar spring 5-1 and two rear return torsion bar springs 5-2 are composed, and the upper end of the front return torsion bar spring 5-1 is connected with the lower cross arm 1-2 of the double wishbone of the control arm 1 of the front suspension , the lower end of the rear reset torsion bar spring 5-2 is connected with the lower cross arm of the rear suspe...

Abstract

The invention which relates to a device for hanging cars, in particular to a twisted bar type device for hanging cars comprises a front twisted bar spring installed in the front hanging of the car and is characterized in that a back twisted bar spring is installed in the hang at the back of the car; the corresponding ends of the front and the back twisted bar spring in the same side are mutually connected through a connection mechanism and connected with a car frame through a location device. As the connection mechanism is arranged between the front and the back twisted bar spring on the same side, a linkage relation is built between the front and the back twisted bar spring on the same side, which can improve effectively the vibration situation in an uneven road surface in the driving process of the car; at the same time, the car frame and a body frame receive no twisted force so that the service life of the car can be prolonged.

Description

technical field [0001] The invention relates to an automobile suspension device, in particular to a torsion bar type automobile suspension device. Background technique [0002] At present, there are mainly two types of suspension systems in automobiles: one is non-independent suspension and the other is independent suspension. The independently suspended axle is divided into two sections, and each wheel is independently installed under the frame with a coil spring, so that when one wheel jumps, the other wheel is not affected, the vibration of the body is greatly reduced, and the comfort of the car is also improved. Great improvement, especially when driving on high-speed roads, it can also improve the driving stability of the car. However, this kind of suspension structure is more complicated, the bearing capacity is small, and it will also make the driving system and steering system of the car more complicated. At present, the front and rear suspensions of most cars have...
