Description

Technical Field

[0001] The utility model relates to the technical field of axle drive of a simulation model vehicle, in particular to an axle drive structure for a simulation model vehicle. Background Art

[0002] A simulation model vehicle is a type of game vehicle that provides players with a feeling of driving a real-life car. In simulation climbing vehicles, the climbing passability of the vehicle has always troubled model enthusiasts. The axle (also known as the axletree) is connected to the vehicle frame (or a unitized body) through a suspension, and wheels are installed at both ends. Its main function is to transmit the acting forces and their torques in various directions between the vehicle frame and the wheels. For a vehicle with a common axle, the ground clearance mainly depends on the height of the axle cross-axis from the ground. As long as the tire radius is large, the ground clearance of the axle is large, and the passing performance is better. Additionally, there is another type of axle called a portal axle. This axle is equipped with a reduction gear between the axle head of the wheel half shaft and the wheel axle, which can raise the axle without increasing the wheel size, thereby increasing the ground clearance and enhancing the passing performance. The servo fixing methods of the portal axle are divided into two types. One is installed on the crossmember, and the other is installed on the axle. Commonly, it is installed on the crossmember. A small number are installed above the axle housing of the portal axle with a relatively high center of gravity. In this type of portal axle, the axle housing is eccentric, and it is fixed beside the axle housing, integrating the servo and the axle, reducing the center of gravity of the axle and increasing the steering torque of the axle. This improves the performance of the axle. The front and rear portal axles can be driven in both forward and reverse directions, solving the axle effect during the running of the model vehicle without changing the gearbox. The characteristics of the portal axle are briefly described here. Advantages: large ground clearance, good passing performance, and large torque; Disadvantages: small torsional angle.
