Abstract
The utility model discloses a novel trackless vehicle driving wheel adjusting mechanism, which comprises a vehicle body, driving wheels and driving wheel installing supports. One end of each driving wheel support is hinged to the vehicle body. The novel trackless vehicle driving wheel adjusting mechanism is characterized in that the other end of each driving wheel support is connected with the vehicle body through a constant pressure system. The constant pressure system is a constant hydraulic pressure system, and a hydraulic oil cylinder of the constant pressure system is respectively hinged to the vehicle body and the driving wheel supports. A cylinder barrel of the hydraulic oil cylinder is hinged to the lower end of an oil cylinder installing frame fixed on the vehicle body, and an extending-out end of a piston rod is hinged to a corresponding end of the driving wheel supports. The novel trackless vehicle driving wheel adjusting mechanism is capable of adapting to road surfaces with slopes and/or sunk road surfaces.
Description
Technical field
The utility model relates to a kind of transport vehicle, relates in particular to a kind of novel trolley-bus driving wheel adjusting mechanism.
Background technology
The trackless transport trolley has been widely used in industries such as automobile, construction machinery and equipment, mould-manufacturing, steel plate dispensing, household electrical appliances manufacturing, is generally used for the transportations in the workshop such as mould, plate, equipment.Existing trolley-bus driving wheel adjusting mechanism comprises car body, drive wheel and drive wheel mounting bracket.Drive wheel mounting bracket one end and car body are hinged, and the other end is by spring and car body resilient connection.The drive wheel of the trackless transport trolley of this structure swing up and down and the pressure of drive wheel road pavement is realized by the spring that is in compressive state.When road surface depression, drive wheel is when lower swing, and spring stretches, and spring reduces pressure moment of drive wheel mounting bracket and then drive wheel road pavement even disappears, and vehicle can't travel.Work as bump, when drive wheel was upwards swung, spring continued compression, and the drive wheel road pavement produces very big pressure, causes the propulsive effort deficiency.The major cause that causes above-mentioned defective is that the elastic force between drive wheel mounting bracket and the car body changes, and causes the fluctuation of pressure of drive wheel road pavement bigger, trackless transport trolley fluctuation of service.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can adapt to gradient road surface and/or depression ground-surface novel trolley-bus driving wheel adjusting mechanism.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of novel trolley-bus driving wheel adjusting mechanism comprises car body, drive wheel and drive wheel mounting bracket, and this drive wheel bracket one end and car body are hinged, and it is characterized in that: the other end of described drive wheel bracket connects with car body by constant-voltage system.
Described constant-voltage system is permanent hydraulic efficiency pressure system, and its hydraulic ram is hinged with car body and drive wheel bracket respectively.
The cylinder barrel of described hydraulic ram is hinged with the oil cylinder erecting frame lower end that is fixed on the car body, and piston rod external part and drive wheel bracket respective end are hinged.
The utility model replaces with constant-voltage system with the spring between drive wheel mounting bracket and the car body, makes car body constant to the power of drive wheel mounting bracket, and then the pressure of drive wheel road pavement remains unchanged, and the trackless transport trolley is stable.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 oil cylinder erecting frame, 2 cylinder barrels, 3 pivots, 4 drive wheels, 5 drive wheel bracket, 6 piston rods, 7 hydraulic rams, 8 car bodies.
The specific embodiment
Connotation of the present utility model is that the spring between drive wheel mounting bracket and the car body is replaced with constant-voltage system, and the pressure of drive wheel road pavement is remained unchanged.Those skilled in the art's general knowledge as can be known; here the constant-voltage system of addressing is to make trying hard to keep between drive wheel mounting bracket and the car body hold substantially invariable system; can pass through hydraulic efficiency pressure system, pressure system or mechanical constant pressure arrangement and the mutual combination realization between them; here only for example the utility model is described in detail with permanent hydraulic efficiency pressure system; what need statement is; protection domain of the present utility model is not limited to this embodiment, everyly can keep power is constant between drive wheel mounting bracket and the car body structure all in protection domain of the present utility model.
Fig. 1 shows the structural representation of trolley-bus driving wheel adjusting mechanism, as can be seen from the figure, trolley-bus driving wheel adjusting mechanism is mainly by car body 8, drive wheel 4, drive wheel mounting bracket 5, hydraulic ram 7 and make oil pressure keep constant permanent hydraulic efficiency pressure system (or be referred to as hydraulic power unit, this system is not shown) to form.The A end of drive wheel bracket 5 is hinged by pivot 3 with car body 8.Between the B end of drive wheel bracket 5 and the car body 8 hydraulic ram 7 is set.Piston rod 6 external parts of hydraulic ram 7 and the B of drive wheel bracket 5 end are hinged, and the cylinder barrel 2 of hydraulic ram 7 is hinged with oil cylinder erecting frame 1 lower end that is fixed on the car body 8.
Certainly, hydraulic ram 7 also can be inverted installation, and promptly piston rod 6 external parts of hydraulic ram 7 are hinged with oil cylinder erecting frame 1 lower end that is fixed on the car body 8, and the cylinder barrel 2 of hydraulic ram 7 is hinged with the B end of drive wheel bracket 5.
Control principle of the present utility model:
Drive wheel 4 swing up and down and the pressure control of drive wheel 4 road pavement is realized by hydraulic ram 7, hydraulic ram 7 is by hydraulic power unit control, to keep hydraulic fluid pressure constant.When the road surface depression, drive wheel 4 is when lower swing, and hydraulic ram 7 piston rods 6 extend, hydraulic fluid pressure descends in the hydraulic ram 7, the instantaneous hydraulic oil that replenishes in hydraulic ram 7 of hydraulic power unit guarantees that the pressure of 7 pairs of drive wheels 4 of hydraulic ram and then road pavement is constant, and vehicle stabilization travels.Work as bump, when drive wheel 4 was upwards swung, hydraulic ram 7 piston rods 6 shrank, the hydraulic oil of hydraulic ram 7 passes back into the fuel tank of hydraulic power unit, the pressure that guarantees 7 pairs of drive wheels 4 of hydraulic ram and then road pavement is constant, and guaranteeing has enough driving friction force, and vehicle stabilization travels.
The utility model can adapt to the cruising on maximum 10% gradient or rough and uneven in surface road surface.
