Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of two-wheel drive pavement milling machine preceding steering and driving axle, its purpose is to solve old-fashioned two-wheel drive pavement milling machine, adopt the central hydraulic fixed displacement motor to drive gearbox reaches to preceding steering mechanical drive axle always, its tractive force is little, cause milling machine can not mill deeply, can not mill soon, climbable gradient is little, the problem that turns to aspect such as fragile to exist before the machinery.
2, technical scheme: the utility model is achieved through the following technical solutions:
Steering and driving axle before a kind of two-wheel drive pavement milling machine is characterized in that: this drive axle comprises that mainly two motors, two reductors, crossbeam, reductor support, bodies connect support, bearing pin, turn to oil cylinder and steering trapezium; The crossbeam two ends are provided with stub; The reductor support is connected with stub; Be fixed with reductor on the reductor support respectively; The input of each reductor links to each other with the output of a motor; Two road wheels are separately positioned in the transcapsidation of two reductors; Be provided with below the crossbeam and turn to oil cylinder, turn to the oil cylinder two ends to be connected with the steering trapezium that two control road wheels turn to respectively; Crossbeam is provided with body and connects support; Crossbeam is provided with bearing pin.
Motor is the bidirectional variable wheel-side motor that the hydraulic-driven reductor rotates that passes through that is arranged on the road wheel inner side edge.
Reductor is the wheel side speed reducer that the reductor shell rotates ground-engaging wheel that passes through that is arranged on the two-wheeled inboard.
3, advantage and effect: by the enforcement of technical solutions of the utility model, can solve old-fashioned two-wheel drive pavement milling machine well, adopt the central hydraulic fixed displacement motor to drive gearbox reaches to preceding steering mechanical drive axle always, its tractive force is little, cause milling machine can not mill deeply, can not mill soon, climbable gradient is little, the problem that turns to aspect such as fragile to exist before the machinery.The utility model advantage and effect are as follows: increased propons tractive force, therefore, under the constant situation of motor traveling pump, can mill dark, mill fast, as mill 60～70mm, mill speed and reach 20～15m/min; Milling dark 60mm than steering and driving axle before traditional machinery is 4～5m/min, and milling the dark just performance of 13m/min of 20mm has by a relatively large margin raising; Use two-wheel drive milling car climbing capacity of the present utility model strong, it can milling on certain slope, can climb up the delivery semitrailer by cat ladder during transportation, climb to get on when having solved before traditional machinery the steering and driving axle transportation and deliver semitrailer, the problem that can only hang with crane, the conveyer discharging is highly high, the high container car that connects material also is suitable for, and steering and driving axle can only connect with the little container car that connects material before the machinery, and the utility model dependability is good, and is not fragile.
