Abstract
A cab suspension mechanism of an off-road dumper comprises a spring, a gas shock absorber, an upper face plate and a lower support. Side plates are arranged on the outer side of the upper face plate and the outer side of the lower support. The rear end of the upper face plate and the rear end of the lower support are connected through a fastening piece to form a U-shaped structure. The lower end of the gas shock absorber and the side plate of the lower support are fixedly welded, and the upper end of the gas shock absorber is connected with the upper face plate. The spring is arranged at the front end of the lower support, a pull rod is arranged between the rear end of the upper face plate and the rear end of the lower support, and the upper end and the lower end of the pull rod are fixedly connected with an upper supporting plate and a lower supporting plate respectively through fastening pieces.
Description
Technical field
The utility model relates to a kind of damping of operator's compartment, relates in particular to a kind of cab suspension damping of haul truck.
Background technology
The operator's compartment of haul truck adopts rigidity setting mostly both at home and abroad at present, the support of operator's compartment and car is directly connected, this traveling comfort that will shine into operator's compartment is inadequate, increase sense of fatigue to navigating mate, also there is part dumping car to consider that this problem has increased damping between operator's compartment and vehicle frame, but the damping of prior art carrys out damping by increase spring installation between operator's compartment and spring mostly, because the elasticity of spring is too large, also can cause the human discomfort of navigating mate.
Utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of haul truck cab suspension mechanism, can effectively absorb the impact that uneven road surface brings, and reduces vibrations, improves travelling comfort,
Alleviate driver and crew's fatigue.
For achieving the above object, the technical scheme basic conception of cab suspension provided by the present invention mechanism is as follows:
One haul truck cab suspension mechanism, comprise spring, gas bumper, top panel and lower bracket, described top panel and described lower bracket rear end connect into U-shaped structure by nut, described top panel and described lower bracket arranged outside have side plate, the plate-side plate welding of described gas bumper lower end and described lower bracket is fixed, described gas bumper upper end is connected with described top panel, described spring is arranged on the front end of described lower bracket, between described top panel and described lower bracket rear end, be provided with pull bar, described pull bar upper and lower side is by fastener and lower carrier plate, top panel is fixedly connected with.
Further, the top cooperation of described spring is provided with upper spring support cover, and spring bottom is provided with spring underlay circle around.
Further, described gas bumper bottom is provided with gas cushion blocking lower bracket.
Further, described top panel front end is connected with pipe.
Further, described pipe is connected with operator's saddle.
Further, described lower bracket front end is provided with the outer pasting board of operator's compartment bracing frame.
Further, the outer pasting board of described operator's compartment bracing frame is connected with the support of car.
The utility model advantage is compared with prior art: operator's compartment of the present utility model damping in the time pressing down, when rising, offset the rising elastic force of spring by gas bumper, make operator's compartment held stationary, this is gas bumper, operator's compartment is damping in the time pressing down, and offsets the rising elastic force of spring when rising, and pull bar can effectively holddown spring, adjust the height between top panel and lower bracket, also play support bracket fastened effect.Make operator's compartment more stable and comfortable in the time of vehicle to run.
Brief description of the drawings
Fig. 1 is the front elevation of the utility model embodiment.
Fig. 2 is the right elevation of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Detailed description of the invention
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Embodiment 1
Shown in Fig. 1, described cab suspension mechanism, the top panel 6 and lower bracket 1, the top panel 6 that comprise cab suspension mechanism have side plate 5 with lower bracket 1 arranged outside, spring 11 is arranged on cab suspension mechanism lower bracket 1 and at lower bracket front end, spring 11 bottoms are provided with spring underlay circle 7 around, spring 11 upper ends cooperations are provided with upper spring support cover 10, can make spring fix and not move, the working stability of keep-spring.Cab suspension mechanism lower bracket 1 and top panel 6 rear ends connect into U-shaped structure by fastener 23, between lower bracket 1 and top panel 6 right sides, are also connected with gas bumper 20.Gas bumper 20 bottoms are provided with gas cushion blocking lower bracket 17.Described gas bumper 20 lower ends and gas bumper lower bracket 17 are welded and fixed, and keep the stability of gas bumper work.Described gas bumper 20 upper ends and described 13 chimeric connections of gas bumper upper bracket, be provided with pull bar 25 between described top panel 6 and lower bracket 1 rear end, and described pull bar 25 upper and lower sides are fixedly connected with lower bracket 1 by fastener 23 with top panel 6.On described top panel 6 front ends, be connected with the pipe 3 being connected with operator's saddle.Described lower bracket 1 front end is provided with the outer pasting board 16 of the operator's compartment bracing frame being connected with the support of car.
But, detailed description of the invention is above exemplary, in order to make those skilled in the art be appreciated that this patent, can not be interpreted as the restriction that this patent is comprised to scope, as long as all any being equal to according to spirit that this patent discloses change or modify, all fall into the scope that this patent comprises.
