Description
Technical field:
The utility model relates to a kind of double track automobile-used outside braking device.
Background technology:
At present, at the double track that tile machinery industry uses, generally, without connecting between two rails, because span between two rails is large, long distance, unavoidable two rails outwards produce elastic deformation when heavy duty, necessary preset clearance between wheelspan and two rails, also must reserve certain gap between the position-limited wheel installed additional and track, car body is in the process of walking, reality is doing left-right swing type walking, walking is unstable, brakes unreliable, there is certain potential safety hazard; Meanwhile, in braking and brake, a kind of actv. parking way also do not had, be all the position resting in needs by slow down now, if the speed of a motor vehicle is too fast, cannot solve the parking inertia of heavy-duty vehicle, positioning precision is poor at all.
Utility model content:
The utility model, in order to make up the deficiencies in the prior art, provides a kind of double track automobile-used outside braking device, and its structure is simple, cheap, and brake is reliable, and accurate positioning, solves problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of double track automobile-used outside braking device, comprise the braking mechanism being arranged on car body two side bottom along length over ends of body direction symmetry, described braking mechanism comprises the housing that is arranged on vehicle bottom, respectively by rotating shaft bias, the one horizontally disposed eccentric wheel relative with orbital position is installed at case inside two ends, on the side side plate of track, the through hole relative with eccentric wheel position is provided with at housing, limited impression is provided with away from the edge, side of track at eccentric wheel, one end of one positive stop be located in housing is installed in limited impression, the other end is fixed on housing away from the side side plate of track, one two ends being located at the connecting rod in housing are hinged and connected with the side of two eccentric wheel near track respectively, the one end of the shift fork that connecting rod and is located in housing is hinged, the other end of shift fork and housing are hinged away from the side side plate of track, the piston rod of the cylinder be located in housing with in the middle part of shift fork is hinged and connected, cylinder is connected with control setup.
The utility model adopts such scheme, and structure is simple, cheap, and rotated by cylinder contact with track side surfaces through shift fork, connecting rod band movable eccentric wheel, brake is reliable, and accurate positioning, is suitable for extensively promoting the use of.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1, housing, 2, eccentric wheel, 3, through hole, 4, limited impression, 5, positive stop, 6, connecting rod, 7, shift fork, 8, cylinder, 9, track.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of double track automobile-used outside braking device, comprise the braking mechanism being arranged on car body two side bottom along length over ends of body direction symmetry, described braking mechanism comprises the housing 1 that is arranged on vehicle bottom, inside housing 1, a horizontally disposed eccentric wheel 2 relative with track 9 position is installed respectively by rotating shaft bias in two ends, on the side side plate of track 9, the through hole 3 relative with eccentric wheel 2 position is provided with at housing 1, limited impression 4 is provided with away from the edge, side of track 9 at eccentric wheel 2, one end of one positive stop 5 be located in housing 1 is installed in limited impression 4, the other end is fixed on housing 1 away from the side side plate of track 9, one two ends being located at the connecting rod 6 in housing 1 are hinged and connected near the side of track 9 with two eccentric wheel 2 respectively, one end of connecting rod 6 and a shift fork 7 be located in housing 1 is hinged, the other end of shift fork 7 and housing 1 are hinged away from the side side plate of track 9, the piston rod of the cylinder 8 be located at in housing 1 in the middle part of shift fork 7 is hinged and connected, cylinder is connected with control setup.
During drag, navigating mate in car body controls two cylinder 8 synchronization actions by control setup, the piston rod of cylinder 8 extends is with movable eccentric wheel 2 clickwise through shift fork 7, connecting rod 6, when positive stop 5 offsets with one end of limited impression 4, eccentric wheel 2 stops the rotation, now eccentric wheel 2 passes through hole 3 height point and track 9 contacts side surfaces, when eccentric wheel 2 vertex contacts with track 9, eccentric wheel 2 axle center, eccentric wheel 2 contact point just in time an angle of 90 degrees vertical with track 9, form outside four-point supporting, realize the object of drag.After parking location action completes, navigating mate controls two cylinder 8 backhauls by control setup, the piston rod of cylinder 8 is retracted and is with movable eccentric wheel 2 left-hand revolution through shift fork 7, connecting rod 6, when positive stop 5 offsets with the other end of limited impression 4, eccentric wheel 2 stops the rotation, and now eccentric wheel 2 de-orbits 9 sides, complete a braking brake circulation, brake is reliable, and accurate positioning, is suitable for extensively promoting the use of.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
