Technical field
The utility model relates to a kind of omni-directionally-floated formula steering unit for front wheels and paver.
Background technology
Wheel-type spreading machine is that one is used for grade maintenance of surface, maintenance, the special construction apparatus that Yi Jizhong, low-grade highway construction pave.Its steering unit for front wheels, as the important device of travelling system of spreader, mainly assume responsibility for the carrying that paver turns to work and propons.
But traditional wheel-type spreading machine steering unit for front wheels, although structure is simple, there are problems in two-wheeled steering hardware before adopting, such as front-wheel carrying is little, the bad adaptability etc. of road pavement injustice.This not only have impact on paver service efficiency, working stability and transport load-carrying capacity, and greatly affects the construction quality of wheel-type spreading machine, to the sustainable development of wheel-type spreading machine, creates larger restrictive function.
Utility model content
For the problems referred to above, the utility model provides a kind of omni-directionally-floated formula steering unit for front wheels and paver, and the adaptive ability of road pavement is strong, and load-carrying capacity is large, is particularly useful for the front-wheel steering walking of wheel-type spreading machine.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of omni-directionally-floated formula steering unit for front wheels, comprise and be arranged on support beam on chassis and steering cylinder, it is characterized in that, described support beam two ends are symmetrically arranged with the first swing span and the second swing span, described first swing span and the second swing span are symmetrically arranged with the first forecarriage and the second forecarriage respectively, first trailing truck and the second trailing truck, the two ends of described steering cylinder are symmetrically connected with the first forecarriage and the second forecarriage respectively, described first forecarriage, second forecarriage, first trailing truck and the second trailing truck are symmetrically arranged with the first front-wheel respectively, second front-wheel, first trailing wheel and the second trailing wheel.
Preferably, one end of described steering cylinder is connected with the first forecarriage by the first deflecting bar, and the other end is connected with the second forecarriage by the second deflecting bar.
Preferably, described support beam is articulated with in the middle part of chassis by supporting pin, and described steering cylinder is set in parallel in the front end of support beam.
Preferably, the front hinge of described first forecarriage and the first swing span is hinged, and the rear hinge of the first trailing truck and the first swing span is hinged; The front hinge of the second forecarriage and the second swing span is hinged, and the rear hinge of the second trailing truck and the second swing span is hinged.
Preferably, be hinged with the first gangbar between described first forecarriage and the first trailing truck, between the second forecarriage and the second trailing truck, be hinged with the second gangbar.
A kind of paver, comprise operator's station, material conveying device and basic car body, it is characterized in that, also comprise the omni-directionally-floated formula steering unit for front wheels described in above-mentioned any one, described steering unit for front wheels is arranged on the chassis of basic car body.
When equipment (such as paver) needs to turn to work, steering cylinder drives the first deflecting bar and the second deflecting bar to move to the left or to the right simultaneously, and then drives two bogie trucks to realize four front-wheels (i.e. the first front-wheel, the second front-wheel, the first trailing wheel and the second trailing wheel) by connecting rod mechanism synchronously to turn to.Because this device strong point all adopts articulated structure, achieve the comprehensive swing of left-right and front-back, so the out-of-flat of road pavement all can adaptive compensation all around.
The utilization of this device, on the one hand avoids equipment (such as wheel-type spreading machine) in work progress, because roadbed injustice causes the inclination of equipment (paver) complete machine, and then causes and cannot carry out levelling, have a strong impact on construction quality of pavement.On the other hand, front four-wheel optimizes mechanical center position, increases load-carrying capacity, improves the domestic shipping weight that paves, and improves machine productivity, has good Social and economic benef@.
The beneficial effects of the utility model are: whole device can overall swinging with support beam, can adapt to the out-of-flat about front-wheel road pavement; Two bogie trucks respectively can swing, can adapt to the out-of-flat of front-wheel road pavement, totally achieve the omnibearing adaptive capacity of paver front-wheel left-right and front-back.The application of this device, substantially increases wheeled serial paver walking performance and quality, has higher economy and social value.
