Title of Invention: Car shock absorber with an hourglass spring

[0001] This car shock absorber has an hourglass spring that can be used in cars with different weights.

Technical Field

[0002] It is related to mechanics, industrial design, car mechanics and physics.

Background Art

[0003] A shock absorber is a mechanical device that is installed next to each wheel to control or dampen the oscillations of the springs. One end of the shock absorber is connected to the cabin or chassis of the car, and the other end is connected to the moving parts of the suspension system, such as the axle shell or axle. In this position, the movement of the spring increases and decreases the length of the shock absorber. The main purpose of using a shock absorber is to dampen the oscillations of the spring. This shock absorber is not under the weight of the car and also, and it does not affect the height of the car. Some shock absorbers can also have these functions and capabilities.

Summary of Invention

[0004] The purpose of inventing a car shock absorber with an hourglass spring, which also has the ability to work in different weights, is to design a special and new form of shock absorber that can bear a wider range of load and force and can also have wider applications.

Technical Problem

[0005] The existing springs are according to Hooke's law (F=kx), where the displacement of the compressed or stretched spring from its equilibrium point (X) and the spring constant (K) are very limited and uniform for each spring. This means that each spring can bear a specific force depending on its unique (K). In the car suspension system based on the constant spring used, the car can bear only a certain weight range. For this reason, the suspension system of passenger cars is different from that of cargo cars, which means that the shock absorbers of cargo cars are very inflexible and ineffective when carrying low weight or no load. Also, passenger cars can only bear a certain force and weight, and they get damaged if the weight exceeds the permissible limit.

Solution to Problem

[0006] The car shock absorber has an hourglass level spring, with the ability to work in different weights, and it has a special and new form of spring. This shock absorber can bear a wider range of force and have a wider application. In existing springs, according to Hooke's law (F=kx), the displacement of the compressed or stretched spring from its equilibrium point (X) and the spring constant (K) are very limited and unique for each spring. This means that each spring can bear a specific force depending on its unique (K). In the car suspension system based on the constant spring used, the car can bear a certain weight range. Thus, the suspension system of passenger cars is different from that of cargo vehicles. This means that the shock absorbers of cargo vehicles are very inflexible and ineffective when carrying a load with low weight or no load. Also, passenger cars can bear a certain force and weight, and more than this amount will cause damage to these vehicles. This car shock absorber consists of the following two parts: 1 shock absorber and 2. hourglass spring. The hourglass spring has a small thickness at the top and a greater thickness at the end of the spring, and the amount of thickness from the top to the end is increasing in each round of the spring. For this reason, when applying pressure, first the rounds of the hourglass spring with a smaller diameter come into action, and then the rounds with a greater thickness of these springs come into action. As the pressure increases, more coils of the spring are engaged. In this position, thinner level springs are placed on the screen and at this time, the level spring also comes into action. All these actions cause the proper functioning of springs and suspension systems in applying different weights and pressures. The hourglass spring piston is inserted into the piston without an oil seal to help the hourglass springs operate easily.

Description of Embodiments

[0021] According to the Fig.1 , it is connected to the room or cabin or chassis of the vehicle by means of a shock absorber, and it has an auxiliary head hub (2) for compacting and maintaining the auxiliary components. The shock absorber has components of the hourglass spring piston (3) that moves inside the shock absorber piston (5). And the piston washer duster of the hourglass spring (4) prevents dust, water, and damage to the piston. The piston of the shock absorber also moves inside the cylinder of the shock absorber (6). The material inside the cylinder can be any suitable fluid material or air and gas for better suspension. The shock absorber assembly is installed to the axle by the axle connection point (7). According to Fig.2, the set of springs consists of two parts: an hourglass spring and a level spring. The upper part of the hourglass spring (22) is placed under the upper plate of the hourglass spring (21 ) and in the designed groove. Then, the middle plate of the hourglass spring (23) is placed under the upper part of the hourglass spring (22) from the groove. After that, the lower part of the hourglass spring (24) is placed under the groove of the middle plate. Then, the lower plate of the hourglass spring (25) is placed under the lower part (24) of its groove and is connected to the auxiliary piston with a bolt and nut. Next, the level spring (26) is placed under the lower plate (25) and then the plate under the level spring (27) is placed in the level spring and connected to the cylinder by welding. The components can be finally used by placing them on top of each other and connecting them to the axle and chassis.

Examples

[0022] This car shock absorber has an hourglass spring with the ability to work in different weights. The shock absorber has a piston component that sits on the piston and shock absorber, and also has an hourglass-shaped set of springs on it. Likewise, all these springs are separated by plates to prevent wear and tear. The plates have grooves to hold the springs in their place, they are placed on top of each other according to the Drawing (2). After installing the shock absorber to the axle and chassis of the car from the installed places, the car suspension system is ready for use. In this suspension system, first the rounds or rings of the hourglass spring, which are thinner, come into action in the hourglass springs and control the lower weights. Then, in higher weights, thicker rounds or rings of the hourglass spring are used based on the thickness that goes from low to high (level spring).

Industrial Applicability

[0023] Car shock absorbers are related to a wide range of industries and are used in them, but the most important application is in the transportation industry, for use in all types of vehicles and generally anywhere shock absorbers are needed. It is obvious that this type of shock absorber, like other shock absorbers in the mechanical industry (washing machines, shock absorbers, press machines, and other devices), cars, and many measuring tools, can have wide applications.
