Embodiment Construction

[0027] The present invention will be further described in detail below with reference to the drawings and embodiments. It is particularly pointed out that the following examples are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only part of the embodiments of the present invention, but not all of them. All other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] See image 3 , image 3 It is a schematic diagram of the overall structure of a preferred embodiment of the automobile chassis of the present invention. The chassis includes a frame 100 and a suspension 200.

[0029] Specifically, the frame 100 includes two main supporting beams 110 and a plurality of connecting beams 120. Preferably, the main supporting beam 110 and the connecting beam 120 are integrated or connected by wel...

Abstract

An embodiment of the invention provides an automobile, a chassis and a suspension of the automobile. The suspension comprises two groups of suspension connecting rods, wherein the two groups of suspension connecting rods are applied to support connection between main support beams on two sides of a frame and wheels respectively; each group of suspension connecting rods at least comprise a first support connecting rod, a second support connecting rod, a third support connecting rod and a fourth support connecting rod, one end of each of the first support connecting rod, the second support connecting rod, the third support connecting rod and the fourth support connecting rod is rotationally connected with a hub shaft of the corresponding wheel, and the other ends are hinged with the corresponding main support beams of the frame respectively. With the adoption of a multi-connecting-rod structure for the suspension, the optimum location of a kingpin caster angle can be realized, front and back directive force from the road surface is greatly reduced, so that smoothness and comfort during accelerating and braking of the automobile are improved, and the stability of straight diving is also guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of automobile chassis, and specifically relates to an automobile, a chassis and its suspension. Background technique [0002] Suspension is the general term for the force-transmitting connection device between the frame of the car and the axle or the wheel. Its function is to transmit the force and torsion acting between the wheel and the frame, and to buffer the transmission from the uneven road to the frame or The impact of the vehicle body and attenuate the resulting vibration to ensure that the car can run smoothly. In the prior art, most of the chassis structures of small and medium-sized cars adopt independent suspensions, and the suspensions of currently commonly used cars are generally MacPherson suspension systems or double wishbone suspension systems. [0003] See figure 1 , figure 1 It is a schematic diagram of the structure of the MacPherson suspension system. Since there are fewer support points betwe...
