Problems solved by technology

However, some local severe vibrations can also cause noise in the powertrain, such as the surface of the transmission housing, a certain part of the engine block, or some parts of the intake and exhaust system, etc. Therefore, only through the power The flexible suspension on the assembly can reduce these local vibrations, and its effect is quite limited. Therefore, the vibration and noise of the power assembly on the car is still a big problem

Embodiment Construction

[0020] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0021] Such as figure 1 , figure 2 and image 3 As shown, the torsional cantilever type shock absorber is mainly used to weaken some local vibrations on the powertrain of the automobile. The shock absorber includes a base 1 and a cantilever 2. The base 1 is hinged with one end of the cantilever 2. The other end of 2 acts on the surface of the vibration source, and a spring 3 is provided at the hinge of the base 1 and the cantilever 2, and the two ends of the spring 3 act on the base 1 and the cantilever 2 respectively, and the force direction of the spring 3 is consistent with the vibration reduction During the use of the device, the external force (that is, the vibration source) acts on the cantilever 2 in the opposite...

Abstract

The invention provides a torsional cantilever type shock absorber, belongs to the technical field of machinery, and solves the problem that the prior flexible suspension technology cannot effectively weaken the noise caused by local vibration on a power assembly. The torsional cantilever type shock absorber comprises a base and a cantilever, wherein the base is hinged with one end of the cantilever, the hinged part is provided with a spring, two ends of the spring acts on the base and the cantilever respectively, the acting force direction of the spring is opposite to the direction of an external force acted on the cantilever when the shock absorber is used, a damping block which is contacted with the base and the cantilever at the same time is arranged between the base and the cantilever, and a friction force formed by the contact of the cantilever and the damping block has the function of slowing down the swing speed of the cantilever. The torsional cantilever type shock absorber can convert some local vibration on an automobile into heat in time to be dissipated so as to effectively weaken the noise produced by the local vibration.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a cantilever type shock absorber, which belongs to the technical field of machinery. Background technique [0002] Vibration of the powertrain in a car is the main source of noise when the car is running at medium / low speeds. In modern cars, the powertrain is fixed with the body in a flexible connection. This connection can greatly reduce the impact of the overall vibration of the powertrain on the vehicle and improve the comfort of the car. However, some local severe vibrations can also cause noise in the powertrain, such as the surface of the transmission housing, a certain part of the engine block, or some parts of the intake and exhaust system, etc. Therefore, only through the power The flexible mounts on the assembly to dampen these local vibrations are quite limited. Therefore, the vibration and noise of the powertrain on the car is still a major problem. Contents of the invention ...
