Description
I. Product Description
This mechanical structure teaching kit for cars is meticulously equipped with a series of precision parts for constructing an electric go - kart. Through this practical activity that deeply integrates the design and assembly processes, under the careful guidance of professional teachers, students can transform into "little engineers". They personally carry out hands - on operations, such as screwing bolts, inserting and assembling parts, to build a "custom - made racing car" with driving functionality.
During this process, students will be exposed to a wealth of valuable knowledge beyond textbooks. For example, there is a significant difference between theory and practice: Parts processed according to theory have no issues in an ideal assembly state. However, in actual processing, due to the inevitable factor of tolerances, they cannot perfectly match the theoretical values. Each part has a certain tolerance, which requires students to apply the professional concepts of assembly and fitting. By means of reasonable assembly and fitting methods, the impact of part tolerances on the overall assembly can be effectively eliminated, ultimately achieving the desired design effect. More importantly, students will deeply understand that technological innovation not only requires unwavering perseverance but also continuous breakthrough spirit. This activity will also greatly stimulate students' strong interest in science and engineering courses such as mechanics, and comprehensively enhance their comprehensive abilities in the learning and practice process.
As a typical STEAM (Science, Technology, Engineering, Arts, Mathematics) educational activity, during the course, students can effectively apply textbook knowledge to practice and solve real - world problems through hands - on operations. In the design and manufacturing segments, students will have the opportunity to practice cutting - edge technologies. Through teamwork, they can jointly realize a practical "car - building dream", and further transform the learning and practice achievements into innovative thinking and entrepreneurial capabilities. This activity focuses on cultivating students' innovative spirit and cooperation ability. By providing rich hands - on practice opportunities and broadening their knowledge horizons, it stimulates students' innovative thinking. The assembled go - kart is equipped with a complete braking system, throttle system, and steering system.
II. Characteristics of Main Parts
1. 48×48mm U - shaped Beam
The 48×48mm U - shaped beam is made of high - strength 6061 aluminum and is elaborately processed by stamping technology. This process significantly improves the stability, firmness, and load - bearing capacity of the U - shaped beam. Its three - side profiles can provide reliable support for the shafts extending perpendicular to the U - shaped beam. Each side of the U - shaped beam is equipped with bearing holes with a diameter of 14 mm. With the rational use of bearings, the maximum load - bearing efficiency of the U - shaped beam can be fully exerted. In addition, due to the distribution of various types of hole positions on the three surfaces of the beam, diverse fixation and combination methods can be achieved. The cleverly designed groove space of the U - shaped beam can properly protect and accommodate various types of motors, batteries, and drive components. When the surfaces of the U - shaped beam are perpendicular to each other, it can provide more powerful support and flexible combinations in multiple directions.
2. Flange Ball Bearing
This bearing is used in coordination with a stainless - steel hexagonal shaft, which can effectively increase the contact area and thus achieve a more uniform distribution of the load. Its performance advantages are more prominent especially when bearing heavy loads or operating at high speeds.
3. Motor
The equipped DC motor has the characteristic of high - power output and can provide stable, efficient, and powerful power support for the go - kart, ensuring smooth vehicle operation.
4. Module 0.8 Steel Gear
The 4303 series pinions offer 5 different choices of the number of teeth. Among them, this 36 - tooth, 8 - mm steel pinion has an 8 - mm hexagonal center hole and can achieve precise matching with the 8 - mm hexagonal shaft, thus generating a strong positive driving force. This driving force is sufficient to handle heavy torque loads without worrying about the deformation of the holes and shafts. It is installed with two fixing screws, which can firmly fix the gear on the 8 - mm hexagonal shaft. There is a circular groove with a depth of 3 mm on the top of the gear. This ingenious design can effectively prevent the gear from contacting both the outer and inner rings of the bearing simultaneously, thus greatly reducing friction. This means that without the need for additional washers, the gear can be closely fitted to the 8 - mm bearing because it only contacts the rotatable inner ring of the bearing. If this function is not available, a separate washer needs to be installed between the bearing and the gear to minimize friction.
