Abstract
The utility model discloses a spacing protection device of suspension bumper shock absorber behind driver's cabin, including the locking support with articulate the bumper shock absorber that constitutes by screw rod, spring and base in locking support below to and the supporting rack, upper and lower spacing is installed respectively to the upper and lower end of bumper shock absorber, goes up to correspond for upper and lower spacing to be provided with upper and lower cushion, install and put up the bolt hookup bumper shock absorber lower extreme lower spacing and fix on the supporting rack, install the last cushion in last spacing of bumper shock absorber upper end, place the last plane baffle of supporting rack in under, and the distance between the baffle of plane on its and the supporting rack is drawn within the atress stroke scope of permission by the bumper shock absorber. When the bumper shock absorber received great drawing or compression, this device received tensilely or the compression promptly, decomposes the effort on the bumper shock absorber, made the bumper shock absorber be in all the time within the atress stroke scope of permission to the effectual bumper shock absorber of having protected has prolonged the life of bumper shock absorber.
Description
Technical field
The utility model relates to a kind of driving cab rear suspension bumper limiting and protecting device, belongs to automotive field.
Background technology
At present, being arranged on the overturn locking device in automobile driving cabin rear-suspending, is all generally be fastened in frame chassis by locking support and the bearing support be hinged on below locking support.In order to alleviate and alleviate the vibrations of jolting that operator's compartment produces in the process of moving because of vehicle, below locking support, be usually hinged with the bumper be made up of screw rod, spring and base.This bumper be arranged on rear-suspending, although can alleviate and alleviate the vibrations of jolting that operator's compartment produces in the process of moving because of vehicle, but when the amplitude of this vibrations of jolting is comparatively large and when exceeding the limit of the stretching of bumper self or compression, then can cause fracture damage or the inefficacy of damper spring, thus reduce the service life of bumper, add human and material resources and the time of bumper maintain and replace.
Utility model content
Technical problem to be solved in the utility model is: be intended to the deficiency overcoming above-mentioned prior art; a kind of driving cab rear suspension bumper limiting and protecting device is provided, protects bumper with actv. and make it remain within the stressed stroke range that it stretches or compression allows.
Its technical scheme is: a kind of driving cab rear suspension bumper limiting and protecting device, comprise locking support and be hinged on the bumper be made up of screw rod, spring and base below locking support, and bearing support, it is characterized in that: the upper and lower end of described bumper is separately installed with upper and lower position-limited rack, and on upper and lower position-limited rack, correspondence is provided with upper and lower rubber cushion; The described lower limit frame being arranged on bumper lower end is fixed on bearing support by Bolt Connection, be arranged on the upper rubber cushion in the upper limit frame of bumper upper end, under the upper plane shuttering panels being placed in bearing support, and the distance on itself and bearing support between plane shuttering panels, within the stressed stroke range that shock absorber allows.
Its beneficial effect is: due to the minimum and maximum forced stroke according to bumper, set the operating range of bumper limiting and protecting device, and namely the operating range of bumper limiting and protecting device is less than the forced stroke that bumper allows.Therefore when bumper is subject to stretching greatly or compressing; namely bumper limiting and protecting device is stretched or is compressed, and has decomposed the application force on bumper, makes bumper be within the stressed stroke range of permission all the time; thus actv. protects bumper, extend the service life of bumper.

Fig. 2 is the lateral plan of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, a kind of driving cab rear suspension bumper limiting and protecting device, the bumper 2 be made up of screw rod, spring and base comprising locking support 1 and be hinged on below locking support, and bearing support 3.The upper and lower end of bumper 2 is separately installed with upper and lower position-limited rack 5,4, and on upper and lower position-limited rack, correspondence is provided with upper and lower rubber cushion 51,41.The lower limit frame being arranged on bumper lower end is connected and fixed on bearing support 3 by bolt 42, be arranged on the upper rubber cushion in the upper limit frame of bumper upper end, under the upper plane shuttering panels 31 being placed in bearing support, and the distance on itself and bearing support between plane shuttering panels, within the stressed stroke range that shock absorber allows.When the bumper tension masterpiece used time, on the supported frame of upper rubber cushion 51 in upper limit frame, plane shuttering panels 31 stops, stops bumper 2 to continue to stretch out, limits the range of bumper; When bumper is stressed effect; upper rubber cushion 51 in upper limit frame abuts with the lower rubber cushion 41 in position-limited rack; bumper is prevented to continue inwardly compression; limit the minimum stroke of bumper; thus make bumper be in the stressed stroke range of permission all the time; actv. protects bumper, extends the service life of bumper.
