Abstract
The utility model relates to a gearbox suspension mechanism for a light passenger car, which comprises a gearbox installing beam and a rear suspension rubber cushion assembly. Two ends of the gearbox installing beam are connected with a transition support frame; the transition support frame adopts folding rod-shaped channel steel, an installing plate is arranged at the vertical upper part, and the lower part is bent towards one side of the gearbox installing beam; and a damping rubber cushion is arranged in the channel steel at the lower part of the transition support frame through a threaded connection piece. The rear suspension rubber cushion assembly comprises a U-shaped rear rubber cushion transition support frame; and two rear damping rubber cushions are arranged on the U-shaped rear rubber cushion transition support frame. The gearbox suspension mechanism solves the problems that the traditional gearbox suspension mechanism has large volume and weight, meanwhile, the vibration of a gearbox suspension soft cushion in the torsion direction is difficult to restrain due to smaller arm force, and particularly, a gearbox has larger torsion angle position and vibration during the starting and stopping process. The suspension soft cushion plays a key role in the vibration reduction and the vibration isolation of an engine. The rear suspension rubber cushion assembly ensures a crossing point of a suspension center line of the rear suspension rubber cushion assembly to pass through the inertia main shaft of the power assembly, therefore, the gearbox suspension mechanism can play a good role in vibration reduction and the vibration isolation.
Description
Technical field
The utility model belongs to the automobile gearbox suspension system, is specifically related to a kind of light bus gear box suspension mechanism.
Technical background
The gear box suspension system is used to support gearbox, guarantee the correct attitude of gearbox, guarantee that the distortion under gearbox gravity and other load-up conditions does not exceed allowed band, guarantee gearbox does not exceed allowed band under the limited conditions of vehicle displacement, simultaneously suspension system also should have and suppresses vibration ability preferably, avoids possible resonance zone.Suspension system generally is installed in the flywheel shell of engine both sides behind the gearbox, suspension system configuration part size in back is bigger for a long time, weight is big, and torsional vibration suppresses ability, often occurs causing accidents such as flywheel shell of engine cracking because of gear box suspension rubber cushion cracking.
The model utility content
For stability and the Security that improves gear box suspension, alleviated the problem of traditional suspend large scale and high weight simultaneously, the utility model provides a kind of gear box suspension that is installed on the light bus.
Concrete architecture advances design proposal is as follows:
A kind of gear box suspension mechanism that is used for light bus comprise gearbox mounting rail 1 and after the rubber cushion assembly 2 that suspends;
Described gearbox mounting rail 1 both sides are bent upwards, and the two ends of gearbox mounting rail 1 are connecting transition bracket by connecting plate; Described transition bracket is a pole shape channel-section steel, and vertical top one side is provided with mounting plate 5, and the bottom is provided with vibration damping rubber cushion 3 by threaded connector to gearbox mounting rail one lateral bending song in the bottom channel-section steel of transition bracket;
The rubber cushion assembly 2 that suspends after described comprises the back rubber cushion transition bracket 4 of U-shaped, vibration damping rubber cushion after back rubber cushion transition bracket 4 inner bottom parts are laid with two, and turn up in back rubber cushion transition bracket 4 two ends, and turn up and locate to be provided with respectively mounting hole in described two ends.
The utility model useful technique effect compared with prior art is embodied in the following aspects:
1, solved traditional gear box suspension structure and had large-size and weight, the gear box suspension cushion arm of force is less simultaneously, is difficult to suppress the torsional direction vibration, particularly in gearbox startup and docking process the bigger torsion angle position and the problem of vibration is arranged.
2, vibration damping, the vibration isolation to motor plays a key effect suspending cushion in the mounting point on the motor: the mounting point of rubber cushion assembly 2 that suspends after this guarantees the principal inertia axis of the junction point of its center of suspension line by power assembly, can play good vibration isolation, damping effect.
3, suspending cushion has guaranteed static stiffness and above-below direction single-degree of freedom vibration vibration isolation efficiency.
