Problems solved by technology

However, the stiffness of the prior art vehicle powertrain rubber shock absorber is not adjustable. With the long-term use of the vehicle, the stiffness of the shock absorber will harden with the aging of the rubber, and the vibration isolation and noise reduction ability will inevitably decline.

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Such as figure 1 As shown, the adjustable rubber damper of the present invention includes an upper frame 3, a lower frame 7, a screw nut 1, a screw 4, a first rubber 5 and a second rubber 6; the upper frame 3, the first rubber 5 and the lower frame The frame 7 is superimposed from top to bottom and is provided with through holes that penetrate up and down. The upper frame 3, the first rubber 5 and the through holes of the lower frame 7 are arranged coaxially; the screw nut 1 is rotatably installed on the through hole of the upper frame 3. Hole; the upper part of the screw 4 is screwed into the screw nut 1 and the lower end of the screw 4 is fixedly connected w...

Abstract

An adjustable rubber shock absorber, a vehicle powertrain having the same, and a vehicle. The adjustable rubber shock absorber comprises an upper framework (3), a lower framework (7), a driving device, a first rubber (5) and a second rubber (6). The upper framework (3), the first rubber (5) and the lower framework (7) are superposed from top to bottom, and are each provided with vertically-oriented through holes, the through holes of the upper framework (3), the first rubber (5) and the lower framework (7) being arranged coaxially. The through hole of the first rubber (5) is in contact fit with an outer peripheral wall of the second rubber (6), and the second rubber (6) is axially movable relative to the first rubber (5). The driving device is connected to the second rubber (6) so as to drive the second rubber (6) to move axially relative to the first rubber (5).

Description

Technical field [0001] The invention relates to the technical field of vehicles, in particular to an adjustable rubber shock absorber. Background technique [0002] As an important type of vibration damping component, rubber shock absorbers have been widely used in various machinery, automobiles, railway locomotives, water vehicles, airplanes and other aircraft. It can be said that rubber shock absorbers are needed wherever vibration reduction and isolation are required. However, the stiffness of the rubber shock absorber of the vehicle powertrain in the prior art is not adjustable. With the long-term use of the vehicle, the stiffness of the shock absorber becomes harder with the aging of the rubber, and the vibration isolation and noise reduction ability inevitably decreases. Summary of the invention [0003] The object of the present invention is to provide an adjustable rubber shock absorber to realize the adjustable stiffness of the shock absorber, offset the increase in stif...
