Description
Technical field
The utility model belongs to the trac. field, relates to a kind of Operator's Cab of Roller Tractor draft hitch.
Background technology
At present, in the big-and-middle-sized wheel-tire tractor that China produces, traditional operator's compartment suspension mostly is made up of rubber elastic element.Because the elastic range of rubber element is less and the damping force characteristics of self, it absorbs, the vibrational energy of loss is less, and damping effect is relatively poor.Also have some to adopt coil spring and the combined tractor cab draft hitch of damper, this draft hitch lacks the horizontal damping of integral type because the limit method of its rear suspension is unreasonable, influences the further performance of its damping effect.
The utility model content
The purpose of the utility model be to provide a kind of rational in infrastructure, use reliable, the better Operator's Cab of Roller Tractor of effectiveness in vibration suppression draft hitch, the traveling comfort when further improving chaufeur work.
The technical scheme of the utility model is: Operator's Cab of Roller Tractor's draft hitch comprises: preceding support assemblies component, left back support assemblies component, right back support assemblies component, lateral connecting rod assembly, left undersetting component and bottom right bearing component; Left undersetting component, bottom right bearing component are connected to transmission system transitional shell both sides; Before support assemblies component bottom be connected to left undersetting component, bearing component top, bottom right, left back support assemblies component, right back support assemblies component bottom respectively with transmission system after mechanism housing and final transmission housing be connected; Preceding support assemblies component, left back support assemblies component, right back support assemblies component top are connected with the longitudinal floor beam rear and front end respectively; Lateral connecting rod assembly two ends are connected with left back support assemblies component bottom, right back support assemblies component top respectively.
About in the preceding support assemblies component rubber bush is arranged respectively.
Respectively there is the lower limit bent plate of a spacing rubber coating and left back support assemblies component, right back support assemblies component lower end to cooperatively interact in left back support assemblies component, the right back support assemblies component.
In left back support assemblies component, the right back support assemblies component vibration damper assembly is arranged respectively, vibration damper assembly respectively through snubber block and left back support assemblies component, right back support assemblies component up and down elasticity be connected.
One yielding rubber cover is respectively arranged in the left and right two ends of lateral connecting rod assembly, and lateral connecting rod assembly left end is connected with left back support assemblies component bottom, and right-hand member is connected with right back support assemblies component top.
The utility model can reach following beneficial effect: through this Operator's Cab of Roller Tractor's draft hitch, can the vibration that tractor chassis is passed to operator's compartment be cushioned and decay, reach vibration and noise reducing, improve and drive and the purpose of travelling comfort.This wheel-tire tractor is simple relatively with operator's compartment draft hitch structure, is convenient to arrange and install that good damping result has higher utility.
Description of drawings
Fig. 1 is the utility model Operator's Cab of Roller Tractor draft hitch structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.As shown in Figure 1, Operator's Cab of Roller Tractor's draft hitch comprises: preceding support assemblies component 9, left back support assemblies component 5, right back support assemblies component 1, lateral connecting rod assembly 4, left undersetting component 10 and bottom right bearing component 12.Left undersetting component 10, bottom right bearing component 12 are connected to transmission system transitional shell D both sides; Before support assemblies component 9 bottoms be connected to left undersetting component 10, bearing component 12 tops, bottom right, left back support assemblies component 5, right back support assemblies component 1 bottom respectively with transmission system after mechanism housing C and final transmission housing B be connected; Preceding support assemblies component 9, left back support assemblies component 5, right back support assemblies component 1 top are connected with longitudinal floor beam A rear and front end respectively; Lateral connecting rod assembly 4 two ends are connected with left back support assemblies component 5 bottoms, right back support assemblies component 1 top respectively.
About in the preceding support assemblies component 9 rubber bush 11 is arranged respectively, support assemblies component 9 forms an elasticity, rotary type structure before making.
Respectively there is the lower limit bent plate 8 of a spacing rubber coating 7 and left back support assemblies component 5, right back support assemblies component 1 lower end to cooperatively interact in left back support assemblies component 5, the right back support assemblies component 1, plays spacing and the effect of protection bumper.
In left back support assemblies component 5, the right back support assemblies component 1 vibration damper assembly 6 is arranged respectively; Vibration damper assembly 6 respectively through snubber block 3 and left back support assemblies component 5, right back support assemblies component about in the of 1 elasticity be connected; Be main damper element in left back support assemblies component 5, the right back support assemblies component 1, play vibration damping and energy-absorbing function.
One yielding rubber cover 2 is respectively arranged in the lateral connecting rod assembly 4 left and right two ends, and lateral connecting rod assembly 4 left ends are connected with left back support assemblies component 5 bottoms, and right-hand member is connected with right back support assemblies component 1 top, improves horizontal cushioning performance.
Operator's compartment rotates around preceding support assemblies component 9 inner rubber linings 11 central axis; Vibration damper assembly 6 easy on and off suspended motion in limited range in left back support assemblies component 5, the right back support assemblies component 1 has bigger suspension stroke; Lateral connecting rod assembly 4 makes has horizontal elastic deformation between operator's compartment and the chassis.Rubber bush 11, vibration damper assembly 6 and 4 combineds action of lateral connecting rod assembly, the vibration that tractor chassis is passed to operator's compartment cushions and decays, and reaches vibration and noise reducing, improves and drive and the purpose of travelling comfort.
