Good riding comfort and a wide riding space are targets which are always pursued by automobile designers, and the existing macpherson suspension, double-cross arm suspension, multi-link suspension and the like have good riding comfort, but have complex structure and high cost. The vertical shock absorber affects the riding space, the torsion beam suspension is a semi-independent suspension, the comfort is general, the shock absorber still affects the riding space, the torsion bar spring suspension is generally applied to a pickup-like passenger-cargo dual-purpose vehicle, the riding comfort is general, the structure is still the guiding mechanism of the existing suspension, and the structure is complex.
Therefore, how to provide a suspension system to simplify the guiding structure is a technical problem to be solved by those skilled in the art.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a suspension system for simplifying a guiding structure. Another object of the present invention is to provide an automobile having the above suspension system.
In order to achieve the above purpose, the present invention provides the following technical solutions:
A suspension system, comprising:
And one end of each torsion bar spring is connected with the trailing arm with the wheel bracket, the other end of each torsion bar spring is connected with the frame, and the two torsion bar springs are arranged in parallel.
Preferably, in the suspension system, the torsion bar spring is connected with the trailing arm through a spline.
Preferably, in the suspension system, an axial direction of an end of the torsion bar spring connected to the trailing arm is limited by a bearing mounted on a bearing housing.
Preferably, in the suspension system, the torsion bar spring is fixed on the frame through a torsion bar seat, and the torsion bar spring is connected with the torsion bar seat through a spline.
An automobile comprising a suspension system, wherein the suspension system is any one of the suspension systems described above.
Preferably, in the above-mentioned automobile, the lengths of the two torsion bar springs are equal, and the distances from the two torsion bar springs to the front axle of the automobile are different.
According to the technical scheme, the suspension system disclosed by the invention can simplify the structure, reduce the cost and provide a larger riding space for an automobile only by positioning and guiding the torsion bar spring and the wheels.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings that are required to be used in the description of the embodiments or the prior art are briefly introduced below, and it is obvious that the drawings in the following description are only embodiments of the present invention, and other drawings can be obtained according to the provided drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic structural diagram of a suspension system disclosed in an embodiment of the present invention.
Detailed Description
In view of this, the core of the present invention is to provide a suspension system to improve the comfort and load carrying capacity of an automobile. Another core of the present invention is to provide an automobile having the above suspension system.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in fig. 1, the present application discloses a suspension system comprising two torsion bar springs 2, wherein one end of the torsion bar springs 2 is connected with a trailing arm1 with a wheel carrier, and the other end of the torsion bar springs 2 is connected with a vehicle frame, and the two torsion bar springs 2 are arranged in parallel. With the above arrangement, the torsion bar spring 2 is used to connect the frame and the wheels, and the torsion bar spring 2 is used to bear vertical load, i.e. load of the vehicle body to the direction of the wheels. Because the torsion bar spring 2 and the wheels are used for positioning and guiding, the application can simplify the structure, reduce the cost and provide larger riding space for the automobile.
In a further embodiment, the torsion bar spring 2 is in spline connection with the trailing arm 1, and the torsion bar spring 2 is fixed on the frame through the torsion bar seat 5. A specific connection of the torsion bar spring 2 is provided here, which can be set according to different needs in practice and which are all within the scope of protection. Specifically, a clamping connection or a limiting connection can be adopted.
The axial direction of the end of the torsion bar spring 2 connected with the trailing arm 1 is limited by a bearing 4 arranged on a bearing seat 3. The torsion bar spring 2 is limited through the bearing 4 and the bearing seat 3, so that the torsion bar spring 2 is prevented from moving in the axial direction, and the stability of the automobile is improved.
In the preferred embodiment, the torsion bar spring 2 is fixed to the frame through the torsion bar seat 5, and the torsion bar spring 2 is connected to the torsion bar seat 5 through a spline. Only one way of connecting the torsion bar spring 2 with the frame is disclosed herein, and spline connection is adopted, so that the stability of connection can be ensured, and meanwhile, the strength of the torsion bar spring is ensured.
In addition, the application also discloses an automobile comprising a suspension system, and in particular, the suspension system is the suspension system disclosed in the embodiment, so that the automobile with the suspension system also has all the technical effects described above, and the description is omitted herein.
The suspension system is characterized in that the lengths of the two torsion bar springs 2 are equal to the corresponding wheel track. Specifically, the lengths of the two torsion bar springs 2 are equal, and the distances from the two torsion bar springs 2 to the front axle of the automobile are different. The arrangement can obtain good suspension stiffness, so that the suspension has the same riding comfort as the independent suspension of the spiral spring; the two torsion bar springs 2 are positioned on the same plane in height, which can obtain larger riding space; with a certain distance in the longitudinal direction (X direction), the wheelbases of the left and right wheels are not equal, which does not affect riding comfort and provides an installation space for the torsion bar spring 2. The wheel motion characteristics of the independent suspension are obtained by the suspension system, and the jumping travel of the wheels is improved, so that the comfort is improved.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
