Problems solved by technology

[0006] 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

[0026] like figure 1 As shown, the upper end of the front torsion bar spring 3 is connected with the control arm 1 of the front suspension of the automobile, the control arm of the front suspension is connected with the wheel 2, and the lower end of the rear torsion bar spring 11 is connected with the control arm 12 of the rear suspension. The lower end of the front torsion bar spring of the 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 front and rear torsion bar springs of the above-mentioned same side 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 bearing...

Embodiment 2

[0030] On the basis of the structure of Embodiment 1, in order to prevent the intermeshed gears from being polluted by various impurities and affecting their service life, as figure 2 As shown, three gears meshing with each other on the same side are placed in the gearbox 14, on the one hand, the working conditions of the gears are changed, on the other hand, after the gearbox 14 is fixed on the vehicle frame 4, the three torsion bar springs on the same side Through the positioning of the gearbox, the mutual meshing of the three gears can be ensured, and three pairs of bearing seats are omitted. 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

[0032] On the structural basis of Embodiment 2, when the control arms of the front and rear suspensions are double-wishbone structures, as image 3 , 4As shown, the upper ends of the front torsion bar springs 3 on the left and right sides are installed on the upper cross arms 1-1 of the front suspension control arms 1 on the left and right sides, and the lower ends of the rear torsion bar springs 11 on the left and right sides are installed on the left and right sides On the upper cross arm of the rear suspension control arm 12, the reset torsion bar spring 5 is made up of two front reset torsion bar springs 5-1 and two rear reset torsion bar springs 5-2, and the front reset torsion bar spring 5-1 The upper end links to each other with the lower cross arm 1-2 of the double wishbone of the control arm 1 of the front suspension, and the rear reset torsion bar spring 5-2 lower end links to each other with the lower cross arm of the rear suspension control arm 12, and the front re...

Abstract

The invention relates to an automobile suspension device, in particular to a torsion bar type automobile suspension device which comprises a front torsion bar spring installed on an automobile front suspension. The torsion bar type automobile suspension device is characterized in that a rear torsion bar spring is installed on an automobile rear suspension, and the opposite ends of the front and rear torsion bar springs at the same side are connected with each other by a connecting mechanism and are connected with a carriage by a locating device. Because of the connecting mechanism arranged between the front and rear torsion bar springs at the same side, a linkage relationship is established between the front and rear torsion bar springs at the same side, so that the vibration of the automobile in the process of running on an uneven road can be effectively improved, and simultaneously the carriage and the body frame can not be affected by the torsion, thereby prolonging the service life of the automobile.

Description

[0001] This application is a divisional application of an invention patent filed on February 23, 2008 with the title of "torsion bar type automobile suspension" and the patent application number: 200810074135.7. technical field [0002] The invention relates to an automobile suspension device, in particular to a torsion bar type automobile suspension device. Background technique [0003] 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...
