As shown in fig. 2 and 3, as another preferred embodiment of the present invention, the suspension mechanism 4 includes:
an upper cross arm 41;
a bolt 45 having one end penetrating the upper arm 41;
a nut installed at one end of the bolt 45 and threadedly coupled thereto;
a bushing 42 provided outside the bolt 45, the bushing 42 being installed in the reduction motor base 34;
and one end of a lower cross arm 43 is connected with one end of the steering knuckle 36 far away from the deceleration motor base 34 through a spherical hinge 44.
In one aspect of this embodiment, one end of the upper cross arm 41 is connected to one end of the reduction motor base 34 through a bolt 45 and a second nut 46, and a bushing 42 is installed between the bolt 45 and an inner hole of one end of the reduction motor base 34 to prevent wheel shimmy; one end of the lower cross arm 43 is connected with the lower part of the steering knuckle 36 through a spherical hinge 44; the other ends of the upper and lower crossbars 41 and 43 are connected to the vehicle body by pins.
Has the advantages that: when the vehicle is emergently braked, the counterforce acted on the tire by the ground can generate a large braking torque around the main pin, and the traditional vehicle is provided with the steering tie rod, so that the braking torques in opposite directions generated by the left wheel and the right wheel can be offset skillfully; when the vehicle with the slide plate type chassis is emergently braked, the brake moment is acted on the automatic wheel module to generate great impact because the steering tie rod is not arranged and each wheel module is independent. In order to reduce the moment generated by emergency braking, the invention optimizes the offset distance of the kingpin by adjusting the inclination angle of the kingpin, and further reduces the self-steering moment of the kingpin under the emergency braking.
The distance between the upper part and the lower part of the steering knuckle 36 is reduced, the material is saved, the space at the upper part of the steering knuckle 36 is saved, the steering motor 31 and the steering speed reducer 32 are convenient to install and arrange; the upper cross arm 43 and the lower cross arm 43 are arranged closer to the wheel center in the height direction of the whole vehicle, so that the length of the upper cross arm 43 and the length of the lower cross arm 43 can be reduced on the premise of meeting the kinematics characteristic of the suspension, and the arrangement of wheel modules is facilitated.
The knuckle 36 is connected to the upper cross arm 41 by a bolt 45, thereby preventing wheel shimmy.
The steering motor 31 and the steering reducer 32 are arranged by deflecting a certain angle, so that a space of a shock absorber in the suspension mechanism is reserved, and meanwhile, the wheels can be enabled to realize a turning angle of-45 degrees to 90 degrees, and the wheels do not interfere with the movement of other mechanisms in the automatic wheel module, so that transverse parking and pivot steering are realized.
The steering mechanism 3 needs to overcome the pivot steering resistance torque and at the same time, needs to have the capability of resisting the emergency braking impact. The automatic wheel module is therefore required to have a high transmission strength and a compact spatial size. According to the three-stage speed reducer designed by the invention, the first stage is bevel gear transmission, the second stage is planetary gear transmission, and the third stage is planetary gear transmission. The invention provides a method for mounting a planetary gear. A through hole is formed in the line of the planetary gear shaft 3234, and a spline groove is formed in the middle of the through hole and used for mounting the planetary gear shaft 3234. The planet gear shaft 3234 is connected with the inside of the planet gear through a spline; the bearings are arranged on two end faces of the planet gear in a groove mode according to the matching of the diameters of the planet gear shafts 3234, and two ends of each planet gear shaft 3234 are in interference fit with the planet carriers 3231 at the two ends respectively. This can shorten the thickness of the carrier 3231 and reduce the axial dimension of the steering reduction gear 32.
