Description
Technical field
The invention belongs to transmission device technical field, relate to a kind of transmission device, especially a kind of transmission device increasing damping.
Background technology
In prior art, the steering swivel system of industrial vehicle, according to turning to the energy used, is divided into mechanical steering system (manual steering system) and the large class of power steering system two.Mechanical steering system relies on the physical efficiency of operating personal completely to handle and turns to, and overcomes steering resisting torque, realizes the angular deflection of wheel flutter.In power steering system, be used for overcoming the energy that steering resisting torque consumes to be provided by primary mover, operating personal only stressedly to be handled system with very little, control turns to, present stage the electric steering system that adopts of a lot of industrial vehicle, the primary mover of employing is stepping motor or coder, this kind equipment due to rotary resistance little, adopt common steering gear to there is the problem that when vehicle travels, bearing circle rotates automatically, be unfavorable for safe operation.
Summary of the invention
The object of the invention is to the shortcoming overcoming above-mentioned prior art, provide a kind of transmission device increasing damping, this mechanism is by increasing the mode of damping, and the rotary resistance that can solve existing steering gear is little, the technical barrier of bearing circle rotation.
The object of the invention is to solve by the following technical programs:
The transmission device of this increase damping, comprise be connected with bearing circle steering wheel shaft, to be set in rotating shaft fixed cover on steering wheel shaft axle body and the stepping motor be connected with steering wheel shaft or coder by first and second shaft bearing; The bakelite damping increasing damping is provided with between described rotating shaft fixed cover and steering wheel shaft.
Above-mentioned bakelite damping circlewise and be set in one end of steering wheel shaft axle body by bakelite retainingf key, convex surface in one end of described rotating shaft fixed cover is provided with and matches with the end face of bakelite damping, the axle body of described steering wheel shaft is also arranged with spring, described bakelite damping is withstood in one end of described spring makes the interior convex surface of its end face and rotating shaft fixed cover fit tightly, and the other end of spring is fixed by the spring interstage sleeve being arranged on steering wheel shaft one end.
First and second shaft bearing branch above-mentioned is arranged on the upper and lower side of rotating shaft fixed cover, and described bakelite damping and the first shaft bearing are divided into the interior convex surface both sides of rotating shaft fixed cover; Described spring interstage sleeve and the second shaft bearing are close to setting.
Above-mentioned steering wheel shaft lower end is connected with stepping motor or coder, and the output shaft of described stepping motor or coder is connected with steering wheel shaft by stepping motor or coder retainingf key; The housing of stepping motor or coder is rigidly connected by bolt and rotating shaft fixed cover.
The present invention has following beneficial effect:
The present invention by arranging bakelite damping between rotating shaft fixed cover and steering wheel shaft, make steering gear bulk less, add the damping turning to transmission, good reliability, therefore, bearing circle rotation or the little technical matters of turning effort can be solved, be particularly suitable for requiring to adopt stepping motor or coder to be the steering gear that signal exports.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 is bearing circle; 2 is steering wheel shaft; 3 is rotating shaft fixed cover; 4 is the first shaft bearing; 5 is bakelite damping; 6 is bakelite retainingf key; 7 is spring; 8 is spring interstage sleeve; 9 is the second shaft bearing; 10 is stepping motor or coder retainingf key; 11 is stepping motor or coder.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, the transmission device that the present invention increases damping comprise be connected with bearing circle 1 steering wheel shaft 2, to be set in rotating shaft fixed cover 3 on steering wheel shaft 2 axle body and the stepping motor be connected with steering wheel shaft 2 or coder 11 by first and second shaft bearing 4,9; The bakelite damping 5 increasing damping is provided with between rotating shaft fixed cover 3 and steering wheel shaft 2.This bakelite damping 5 circlewise and be set in one end of steering wheel shaft 2 axle body by bakelite retainingf key 6, convex surface in one end of rotating shaft fixed cover 3 is provided with and matches with the end face of bakelite damping 5, the axle body of steering wheel shaft 2 is also arranged with spring 7, described bakelite damping 5 is withstood in one end of spring 7 makes the interior convex surface of its end face and rotating shaft fixed cover 3 fit tightly, and the other end of spring 7 is fixed by the spring interstage sleeve 8 being arranged on steering wheel shaft 2 one end.First and second shaft bearing 4,9 branch described is arranged on the upper and lower side of rotating shaft fixed cover 3, and bakelite damping 5 and the first shaft bearing 4 are divided into the interior convex surface both sides of rotating shaft fixed cover 3; Described spring interstage sleeve 8 and the second shaft bearing 4 are close to setting.Described steering wheel shaft 2 lower end is connected with stepping motor or coder 11, and the output shaft of stepping motor or coder 11 is connected with steering wheel shaft 2 by stepping motor or coder retainingf key 10; The housing of stepping motor or coder 11 is rigidly connected by bolt and rotating shaft fixed cover 3.
Bearing circle 1 of the present invention rotarily drives steering wheel shaft 2 and rotates, steering wheel shaft 2 rotarily drives bakelite damping 5, spring 7 rotates, stepping motor or coder 11 rotating shaft rotate, bakelite damping 5 and rotating shaft fixed cover 3 sliding block joints, the pressure of spring 7 adds the pressure between bakelite damping 5 and rotating shaft fixed cover 3, add the turning effort of steering wheel shaft 2, achieve the increase of steering gear damping.
Operating personal steering wheel rotation, bakelite damping is driven to rotate by steering wheel shaft, the end face that the pressure of spring adds bakelite damping is connected damping with the interior convex surface of the solid top cover of rotating shaft, increase the actuating force of bearing circle, by the adjustment of spring pressure, the requirement of steering force can be met, prevent rotation during bearing circle pure rolling.
