Description

M431106 V. New description: [New technical field] This creation relates to an innovative spherical wheel set with a ball-type wheel drive control function, especially for a multi-configuration designer. To the prior art

According to the 'mesh 4 electric vehicle lightly using the general four-wheeled electric vehicle, electric driving to know the direction of the electric vehicle to change direction, it is necessary to drive the wheel when you want to stop, it is also convenient to use the road, if the user is a novice or a skill It takes more time to stop at the right place, and there is no such thing as the use of the wheel structure with the phase and traverse function. The certificate No. M317853 has a new patent case with a straight line. In the case, the two legs of the cruciform holding unit are held by the first and second starting units, and the starting wheel of the element is brought into contact with the starting wheel of the spherical main starting unit. In the electric test, it is found that the following problems still exist. Because the starting wheel of the second starting unit of the conventional electric vehicle wheel set is the main wheel, the first and second start are very popular in the daily life. , electric wheelchairs, etc. The direction of the body is straight forward or backward, and the direction of the steering direction is changed. The technique of stopping the parking, so the operation is not skillful, it is often more than one. If the parking position is small, it is ideal. The vehicle industry has developed a wheeled vehicle with a direct related patent, such as the Republic of China and the traverse electric vehicle. The main structure is a ball-shaped main wheel that is borrowed from the limit. By means of the servo motor and the starter wheel, straight rolling can be produced by the first starter wheel, and transverse rolling can be produced by the moving ball-shaped main wheel. The vehicle's wheel structure is constructed in practical applications: The design of the first starting unit is different from the wheel axis. The starting wheel pair that is in contact with one of the ball units can be made from a straight group. When driving with the M431106 main wheel, the other starter wheel will hinder the rolling of the spherical main wheel because the wheel axis direction is different. Based on this problem, the conventional structure design must be reinstalled. The clutch mechanism has separately controlled the clutching of the starting wheels of the first and second starting units, that is, when the starting wheel of the first and second starting units drives the spherical main wheel, the other The starting wheel will be out of contact with the spherical main wheel, thereby solving the aforementioned problem, and as a result, the complexity and installation cost of the driving control member are inevitably increased, and there is a need to improve it. Or, perhaps, the starting wheel setting position of the first and second starting units can be lowered to be close to the maximum diameter position of the spherical main wheel (ie, the height position of the rotating center) to block the starting wheel from the spherical main wheel. The degree is reduced to the minimum, but in this case, since the setting position of the starting unit will fall on the outer side of the largest diameter of the spherical main wheel, it is necessary to greatly increase the maximum outer diameter of the holding unit, resulting in an increase in product volume and inconvenience to lightness. The problem of the development trend of miniaturization and miniaturization. Therefore, in view of the problems existing in the above-mentioned conventional ball-type wheel drive structure, how to develop an innovative structure that is more ideal and practical, is expected by the users, and is also related to the industry's efforts to develop breakthrough goals and directions. In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation. [New content] The main purpose of this creation is to provide a multi-directional drive structure for a spherical wheel. The problem to be solved is to develop a new type of spherical wheel drive that is more ideal and practical. The structure aims to improve and innovate breakthroughs; the technical characteristics of the problem solving of this creation are mainly due to the fact that the multi-directional drive 4 M431106 spherical wheel direction is less than one phase, and the driving component should be driven to drive each other. The surface wheel can be used to cause each other to reduce the circumference of the rotating wheel of the different laterally moving device type wheel of the actual clothing surface, and the spherical wheel is different in time, the friction often interferes with the creation of the product. Advance external pre-production; the multi-drive is driven to drive the surface, and the axial direction is dragged. When the rotation of the drive is reversed, the state is close to the zero. The center of the wheel is provided with a peripheral action of the moving wheel; the axial axis of the rolling element wheel is a fulcrum rotation and the spherical wheel rolling element is arranged in a different lateral direction. The line drive can achieve a smooth structure and saves the structure. The existing wheel has a multi-spherical wheel to the side of one axle. The braking feature is: 'and the rollers are perpendicular to each other when the roller is turned The rotation axis will be driven or dislocated by the different types of the ball wheel without the new unique design and the position of the production cost is stabilized. By driving the structure wheel, the driving is rotated, so that the friction group has the spacer ring and the driving. The wheel is driven by the wheel, and when the peripheral wheel of the driving wheel is pivoted, the ball wheel technology is used for the purpose of the ball wheel technology, and the utility is more efficient in operation to package the drive belt column β and the wheel surface.
