Description
Technical field
The utility model relates to car engine suspension structure, is specifically related to back suspension device of engine.
Background technology
The back suspension device of engine structure of existing band position limiting structure generally includes suspension upper plate, suspension lower plate and rubber damper, suspension upper plate is used for being connected with change-speed box, suspension lower plate is used for being connected with vehicle frame, rubber damper sulfuration is fixed between suspension upper plate and suspension lower plate, plays the effect of vibration damping.
The subject matter that present structure exists is: during sudden stop, and change-speed box drives suspension upper plate to preshoot, rear-suspending is not arranged corresponding preshooting resistent position limiting structure prevent suspension upper plate before momentum excessive; Reversing emergency brake time, change-speed box drive suspension upper plate to backlash, rear-suspending is not arranged corresponding anti-backlash structure prevent suspension upper plate after momentum excessive.No matter be that front momentum is excessive, or after momentum excessive, all likely cause driving engine operationally to collide to produce with other parts and be out of shape, and the shearing force that rubber damper is subject to is excessive and cut-off, finally cause rear-suspending to be in failure state, form certain potential safety hazard.
Utility model content
The utility model is intended to the structure optimizing rear-suspending, avoids rear-suspending to lose efficacy, eliminates safe hidden trouble.
For this reason, the technical scheme that the utility model adopts is: a kind of back suspension device of engine with position limiting structure, comprise suspension upper plate (1), suspension lower plate (2), and sulfuration is fixed on the rubber damper (3) between suspension upper plate (1) and suspension lower plate (2), described suspension upper plate (1) is provided with two bolt through-holes (1c) for being connected with change-speed box, suspension lower plate (2) upper left right septum is provided with two projection welding of screws (5) for being connected with vehicle frame, it is characterized in that: the two ends, left and right of described suspension upper plate (1) vertically extend down, to cross behind the termination of suspension lower plate (2) inwards horizontal-extending again, the rear end of described suspension upper plate (1) is provided with the preshooting resistent positioning plate (1a) inwards extended, and leave gap between preshooting resistent positioning plate (1a) and suspension lower plate (2), anti-backlash positioning plate (2a) is extended to form again straight up after extending back in the middle part of described suspension lower plate (2) rear end, there is anti-backlash rubber damping block (4) at the upper cover of described anti-backlash positioning plate (2a) and fixed by sulfuration, between described anti-backlash rubber damping block (4) and suspension upper plate (1), also leaving gap, the middle part of described suspension upper plate (1), suspension lower plate (2) is recessed to form medial recess district down respectively, described anti-backlash rubber damping block (4) is positioned at the dead aft in medial recess district, and described bolt through-hole (1c) staggers with projection welding of screws (5) front and back and arranges.
The beneficial effects of the utility model: set up preshooting resistent positioning plate on suspension upper plate, and leave gap between preshooting resistent positioning plate and suspension lower plate, when sudden stop, change-speed box drives suspension upper plate to preshoot, be against the aft end face of suspension lower plate until preshooting resistent positioning plate till; Suspension lower plate sets up anti-backlash positioning plate, and on anti-backlash positioning plate, be set with the fixing anti-backlash rubber damping block of sulfuration, also leave gap between anti-backlash rubber damping block and suspension upper plate simultaneously, during reversing emergency brake, change-speed box drives suspension upper plate to backlash, anti-backlash positioning plate and anti-backlash rubber damping block can prevent the excessive backlash of suspension upper plate, and play the effect of vibration damping.Set up depressed area to increase the intensity of whole rear-suspending at the middle part of suspension upper plate, suspension lower plate, prevent from further producing distortion in rear-suspending use procedure.Stagger before and after bolt through-hole and projection welding of screws and arrange, be convenient to arrange, avoid producing and interfere.Structure is simple, design ingenious, Be very effective, eliminates suspension upper plate and relatively suspends lower plate excessive movement and cause rear-suspending to lose efficacy, caused potential safety hazard.

Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
The back suspension device of engine of the band position limiting structure shown in composition graphs 1-Fig. 3, primarily of compositions such as suspension upper plate 1, suspension lower plate 2, rubber damper 3, anti-backlash rubber damping blocks 4, entirety is bilateral symmetry.
Suspension upper plate 1 for the lower plate 2 that is connected with change-speed box, suspend for being connected with vehicle frame, rubber damper 3 sulfuration is fixed on and suspends upper plate 1 and suspend between lower plate 2.Suspension upper plate 1, suspension lower plate 2 are stamping forming sheet metal component.The upper left right septum of suspension upper plate 1 is provided with two bolt through-hole 1c for being connected with change-speed box, and the upper left right septum of suspension lower plate 2 is provided with two projection welding of screws 5 for being connected with vehicle frame.Stagger before and after bolt through-hole 1c and projection welding of screws 5 and arrange.
The two ends, left and right of suspension upper plate 1 vertically extend down, to cross behind the termination of suspension lower plate 2 inwards horizontal-extending again.The rear end of suspension upper plate 1 is provided with the preshooting resistent positioning plate 1a inwards extended, and the local, rear end of suspension lower plate 2 covers by preshooting resistent positioning plate 1a.Between preshooting resistent positioning plate 1a and suspension lower plate 2, leave gap, making suspension upper plate 1 relatively suspend lower plate 2 can move forward in interstice coverage.
