Embodiment Construction

[0013] The present invention will be further described below in conjunction with the drawings.

[0014] Such as figure 1 As shown, the schematic diagram of the switchable semi-active engine suspension of the present invention. The switchable semi-active engine suspension includes a suspension bracket, a rubber main spring, an inertial channel body, a decoupling diaphragm, a bottom film, a base, and a suspension state switching device. The rubber main spring is set in the suspension bracket through which the rubber main spring passes The suspension bracket is fixed on the subframe, and the suspension bracket protects the interior of the suspension, restricts the displacement of the internal rubber main spring, and realizes the connection between the suspension and the subframe. The main rubber spring of this scheme has two main functions. One is to bear the static and dynamic load of the engine, and the other is to act like a pumping piston, so that the damping fluid passes throug...

Abstract

The invention relates to a switching type semi-active engine mount. The switching type semi-active engine mount comprises a mount bracket, a rubber main spring, an inertia channel body, a decoupling membrane, a base membrane, a base and a mount state switching device, wherein the inertia channel body comprises an upper half inertia channel body and a lower half inertia channel body, the decoupling membrane is clamped and fixed between the upper half inertia channel body and the lower half inertia channel body, a decoupling damping cavity is formed between the decoupling membrane and the lower half inertia channel body, a mount state switching through hole communicated with the decoupling damping cavity is formed in the middle of the lower half inertia channel body, the mount state switching device is arranged in a cavity of the base and comprises an electromagnetic power device and a mount state switching ejector rod, and the electromagnetic power device pushes the mount state switching ejector rod to block or unblock the mount state switching through hole so as to switch the rigid damping state of the engine mount. The damping performance of the mount is adjusted by the mount state switching device according to different working states of a vehicle engine, and the engine mount has the advantages of being good in damping effect and sound insulation effect and high in adaptability.

Description

Technical field [0001] The invention relates to an engine suspension, in particular to a switching type semi-active engine suspension, and belongs to the field of engine suspension. Background technique [0002] Automobile engine mount is an elastic damping connection system between the automobile power system and the body, and it is a key factor affecting the NVH performance of the vehicle. Automobile powertrains are usually divided into two types: horizontal arrangement and longitudinal arrangement. When arranged horizontally, it usually includes 1 engine mount, 1 gearbox suspension, 1 or 2 swing supports. When arranged vertically, it usually includes 2 Engine mounts arranged on the left and right, and a rear gearbox mount. As an important part of the elastic vibration damping connection between the engine and the body chassis, the suspension has the following functions: (1) bear the static and dynamic load of the powertrain; (2) limit the collision and interference between th...
