Embodiment 1

[0027] Embodiment 1: as Figure 1-5 As shown, the incomplete gear periodic meshing steering device includes steering wheel 1, front fork 2, rocker I3, rocker II4, slider 5, shaft I10, crank 17, pin 18, spur gear IV19, connecting rod 20, Limiting part 21, vehicle chassis 22, bearing seat III 23, bearing seat IV 24, bearing seat V 25, bearing seat VI 26, guide rod 27, shaft IV 31, variable number of teeth incomplete gear mechanism 33; The fork 2 is connected, and the front fork 2 is installed on the front end of the chassis 22 to form a rotating pair with the chassis 22. The rocker I3 is fixedly connected to the front fork 2, and the slider 5 can be fixedly connected to the groove of the rocker I3 according to different requirements. position, two guide rods 27 are installed on the rocker II4, and the two guide rods 27 are connected with two stoppers 21 to form a moving pair, and the stoppers 21 are fixed on the chassis 22; one end of the rocker II4 is connected to the connectin...

Embodiment 2

[0032] Embodiment 2: The device structure of this embodiment is the same as that of Embodiment 1, the difference is that the number of teeth of each incomplete gear in the variable number of incomplete gear mechanism is 7, and the incomplete gear on the right side of the variable number of teeth incomplete gear mechanism is rotated. Gear II 30, so that the incomplete gear mechanism with variable number of teeth is divided into 2 tooth areas, each tooth area has 14 teeth, and the angle between the centerlines of adjacent tooth intervals is 180 degrees. Through this incomplete gear mechanism with variable number of teeth 33, it can realize The steering range of the steering wheel 1 is changed between -45° (left direction) and 45° (right direction).

Embodiment 3

[0033] Embodiment 3: as Figure 6 As shown, the incomplete gear periodic meshing steering device includes steering wheel 1, front fork 2, rocker I3, rocker II4, slider 5, cylindrical gear I6, motor 7, cylindrical gear II8, driving wheel 9, shaft I10 , Cylindrical gear III11, shaft II12, bearing housing I13, bearing housing II14, shaft III15, driven wheel 16, crank 17, pin 18, cylindrical gear IV19, connecting rod 20, limiter 21, chassis 22, bearing housing III23, Bearing seat Ⅳ24, bearing seat Ⅴ25, bearing seat Ⅵ26, guide rod 27, shaft Ⅳ31, incomplete gear mechanism with variable number of teeth 33; steering wheel 1 is connected with front fork 2 through hinge pin shaft, and front fork 2 is installed on the chassis The front end of 22 and the chassis 22 form a rotating pair, the rocker I3 is fixedly connected to the front fork 2, the slider 5 can be fixedly connected to different positions on the groove of the rocker I3 according to requirements, and two guide rods 27 are inst...

Abstract

The invention relates to an incomplete gear periodic meshing steering device with adjustable number of teeth, belonging to the technical field of mechanical innovation, which includes a steering wheel, a front fork, a rocker I, a rocker II, a slider, a shaft I, a crank, a pin, Cylindrical gear IV, connecting rod, limiter, chassis, bearing housing III, bearing housing IV, bearing housing V, bearing housing VI, guide rod, shaft IV, incomplete gear mechanism with variable number of teeth; composed of crank, connecting rod, The connecting rod mechanism composed of rocker Ⅰ, rocker Ⅱ, and limit parts is used as a planar crank-rocker mechanism; it is composed of incomplete gear Ⅰ, incomplete gear Ⅱ, friction washers, bearings, and one-way plane thrust bearings to form a variable number of incomplete teeth. Gear mechanism; a variable number of teeth incomplete gear mechanism and a complete gear form a periodic adjustment mechanism; the variable number of teeth incomplete gear mechanism of the present invention has a self-locking function, which greatly reduces the deviation caused by vibration, and through other auxiliary mechanisms The range of the left and right swing angles and the proportion of the period of the left and right swing angles can be arbitrarily allocated by cooperation.

Description

technical field [0001] The invention relates to a periodic meshing steering device with incomplete teeth, in particular to an incomplete gear periodic meshing steering device with an adjustable number of teeth, and belongs to the field of mechanical technology. Background technique [0002] With the development and progress of science and technology, more and more innovative mechanisms are applied in all walks of life, resulting in various mechanical mechanisms, especially those that can realize specific functions. [0003] It is widely used in people's daily life, industrial production and automatic work in some dangerous environments. For example, in an explosion-proof site, when there are some obstacles with specific rules, a device that can just bypass the obstacles and transport the automatic dismantling equipment Go to the designated location to implement the EOD task. [0004] However, due to structural limitations of the traditional crank-link steering mechanism, st...
