Description

Z-shaped balancing pole for vehicle
Technical Field
The invention relates to a Z-shaped balance bar for a vehicle, in particular to a Z-shaped balance bar for FSAE racing cars.
Background
The stabilizer bar is one of the important parts on the automobile. The stabilizer bar does not function when the vehicle is driven on a horizontal road or on a road with the same bumps and depressions. However, when the vehicle makes a sharp turn or makes an emergency obstacle avoidance (i.e., when the horizontal heights of the left and right wheels are not uniform) while traveling at a high speed, the vehicle is very likely to roll and roll. At this point, the stabilizer bar provides a roll stiffness that effectively prevents the vehicle from rolling and tipping over.
The balance rod for the existing automobile is composed of a carbon fiber rod, two connecting pieces and two metal frames, light weight is achieved through the carbon fiber rod, and the support rod and the metal frames form a triangular structure to enable the balance rod to be stressed stably. This scheme has realized that a weight is slim and graceful and automobile balancing pole that intensity is high. However, FSAE racing (chinese college electric formula racing) is more demanding in terms of acceleration, braking, maneuverability, etc., and requires the stabilizer bar to provide different roll stiffness for different tracks and different play items. The existing automobile balance rod is not beneficial to adjusting the rigidity of the roll angle, and the installation and the arrangement are not suitable for FSAE racing.
Disclosure of Invention
Aiming at the defects of the current automobile balancing pole, the invention aims to: a Z-shaped balance bar for a vehicle is provided, which can meet the performance of an FSAE racing car and enable the FSAE racing car to exert better dynamic performance. Meanwhile, the adjustable roll angle rigidity can be provided, and the rigidity adjusting range is wide; the stiffness adjustment curve is continuous; the installation is easy; and the light weight is satisfied.
The invention mainly changes the deformation quantity of the Z-shaped balance bar spring so as to change the roll angle rigidity provided by the Z-shaped balance bar spring when adjusting the rigidity provided by the balance bar. After the Z-shaped balancing pole is installed, the Z-shaped balancing pole spring can only rotate around the pin, when the Z-shaped balancing pole spring is subjected to forces on the same side, the Z-shaped balancing pole spring can deform, and the deformation quantity of the Z-shaped balancing pole spring can influence the roll angle rigidity provided by the Z-shaped balancing pole. The adjusting mode is more convenient and faster.
The roll angle rigidity adjusting range provided by the invention is wider, the roll angle rigidity is adjusted more continuously, and a user can debug the roll angle rigidity more conveniently to obtain the roll angle rigidity more suitable for racing cars.
The invention has small volume, light weight and small occupied space, is more suitable for racing cars and is beneficial to realizing the light weight of the racing cars.
As a further improvement to the embodiment of the present invention, the base and the lifting lug can be designed as a whole without being connected together by bolts.
As a further improvement of the embodiment of the present invention, the pull rod may be designed as a carbon fiber tube, and an aluminum joint is used to connect the carbon fiber tube and the aluminum joint by bonding instead of the welding sleeve.
As a further improvement to the embodiment of the present invention, the Z-shaped balance bar may be designed to be cylindrical at the center and mounted with the base and the lifting lug through bearings.
The embodiment of the invention has the following beneficial effects:
1. the arrangement and installation of the FSAE racing car are suitable, the structure is simple, the weight is light, and the light weight of the FSAE racing car is facilitated;
2. the roll angle rigidity provided by the invention is adjustable, the adjusting range is wide, and the rigidity change curve is continuous.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 1 together, fig. 1 is a schematic diagram illustrating an installation of a Z-shaped stabilizer bar for a vehicle in an FSAE racing car according to an embodiment of the present invention, and fig. 2 is a schematic diagram illustrating a structure of the Z-shaped stabilizer bar for a vehicle according to an embodiment of the present invention.
Referring to fig. 1, the lifting lug is welded to the frame; the limiting block 1 is connected to the lifting lug 3 through a bolt; the Z-shaped balancing rod spring 4 is connected with the limiting block 1 to limit the Z-shaped balancing rod spring to rotate only around the pin 1.4; the two pull rods 2 are connected with the Z-shaped balancing rod spring 4 in tandem through nuts to form a letter Z shape; the other end of the pull rod 2 is connected with the rocking blocks on the left side and the right side through bolts; the rocking block is connected with the fork arm through a push rod. The limiting block 1 consists of a hoop 1.1, a base 1.2, a limiting plate 1.3, a pin 1.4 and a self-lubricating copper sleeve 1.5; the self-lubricating copper sleeve 1.5 is in interference fit with the base 1.2.
It should be noted that the frame, rockers, yoke and pushrod are part of the FSAE race car and are not part of the Z-shaped balance bar for the FSAE race car of the present invention, and their structure and function will be clear to those skilled in the art, and thus the frame, rockers, yoke and pushrod will not be described in any greater detail herein.
The wheel jumps up/down to drive the rocker to rotate and thus transfer force to the Z-shaped balancing beam spring 4. When two wheels jump up and down (namely the racing car has a roll tendency), the two balance bar pull rods 2 move at the same side, and the two ends of the Z-shaped balance bar spring 4 are subjected to forces at the same side to enable the Z-shaped balance bar spring 4 to bend and deform. Because the Z-shaped balance bar spring 4 has certain rigidity, the racing car can resist the rolling of the racing car, so that the racing car has better operating performance on uneven road surfaces.
After the Z-shaped balancing rod spring is installed, the Z-shaped balancing rod spring can only rotate around the pin, when the Z-shaped balancing rod spring is subjected to two forces on the same side, the Z-shaped balancing rod spring can be bent, the deformation quantity of the Z-shaped balancing rod spring can influence the roll angle rigidity provided by the Z-shaped balancing rod, and the deformation quantity of the Z-shaped balancing rod spring is larger at the positions, which are farther from the pin, of the two ends of the Z-shaped balancing rod, so that the specific adjusting method mainly adjusts the roll angle rigidity provided by the Z-shaped balancing rod by changing the number and the size of gaskets at the two ends of.
As a further improvement to the embodiment of the present invention, the Z-shaped balance bar spring 4 may be designed to be cylindrical at the center and mounted with the base 1.2 and the lifting lug 3 through bearings. At the moment, when the roll angle rigidity provided by the Z-shaped balancing rod is adjusted, the spring section can be changed only by rotating the Z-shaped balancing rod spring 4, so that different roll angle rigidities are provided.
It should be noted that the above-mentioned structure of the Z-shaped balance bar is only one embodiment capable of implementing the present invention, and the present invention is not limited to the above-mentioned embodiment as long as it is satisfied that the Z-shaped balance bar spring is mounted on the above-mentioned ear and the above-mentioned ear has a groove so that the Z-shaped balance bar spring can pass therethrough.
Compared with the prior art, the invention has the beneficial effects that: the Z-shaped balancing rod for the vehicle is more suitable for arrangement and installation of the FSAE racing vehicles, has a simple structure and light weight, and is beneficial to light weight of the FSAE racing vehicles; the roll angle rigidity provided by the invention is adjustable, the adjusting range is wide, and the rigidity change curve is continuous.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes and substitutions that are not thought of through the inventive work should be included in the scope of the present invention.
