Description

Technical Field

[0001] This utility model relates to the technical field of four-wheel right-angle steering devices, specifically a four-wheel right-angle steering device with lifting function. Background Technology

[0002] The increasing number of cars on the market, coupled with the lagging development of urban roads, makes it extremely difficult for vehicles to turn and make U-turns on narrow roads, causing great inconvenience to people's travel. Moreover, on slippery roads, the reduced coefficient of friction can cause vehicles to lose control and lead to traffic accidents.

[0003] The development of four-wheel right-angle steering technology can effectively solve the above problems. However, the current four-wheel right-angle steering devices have poor functionality and low practicality. Based on this, we propose a new type of four-wheel right-angle steering device with lifting function. It can both expand the vehicle and function as a lifting device. It can be applied to scenarios such as changing tires and inspecting the chassis. It can also be used for fixed-point lifting scenarios, such as high-level assembly on the assembly line and loading goods in warehouse logistics. It has the advantages of small size, convenient operation and high reliability. Utility Model Content

It can meet the requirements of simultaneous steering of the front axle dual wheels, steering of the rear axle dual wheels, simultaneous 90-degree steering of all four wheels, simultaneous diagonal steering of all four wheels (0° to 90°), and independent steering of a single wheel. The wheel rotation direction is as follows: Figure 1 The direction of the arrow can achieve a 90-degree right-angle turn and reverse reset. Furthermore, the upper and lower control arm bodies are designed with straight arms near the tire side, which is conducive to meeting the right-angle rotation stroke. This enables the device to achieve the advantages of multiple steering modes, including four-wheel right-angle steering.

[0014] (2) This four-wheel right-angle steering device with lifting function optimizes its performance by installing a wireless signal transceiver module.

The radio frequency transceiver built into the remote key, together with the wireless signal transceiver module inside the main lifting device, parses the control command and sends a receiving command to the lifting controller inside the main lifting device. The lifting controller then controls the corresponding lifting motor inside the main lifting device to rotate forward and backward. At this time, the lifting motor, together with the transmission action of the motor spline and spline shaft, realizes the raising or lowering operation of the main lifting device. Furthermore, the main lifting device is flexibly installed on the top of the chassis body with screws, which can be installed in a wide range and realize the lifting and lowering control of goods. This realizes a flexible and automated cargo lifting function. On the other hand, the support lifting device is installed on the lower surface of the chassis body with screws. Normally, it is in a closed device and fits against the lower floor of the chassis. When lifting is required, the user can press the remote key, and with the driving action of the lifting motor and the transmission action of the motor spline and spline shaft, the chassis will be gradually raised or released and the chassis will be lowered to the ground and reset. This allows the device to automatically raise and lower the chassis body as needed, which is convenient for maintenance and chassis inspection and other scenarios.

[0015] (3) The four-wheel right-angle steering device with lifting function is equipped with motor splines, etc., so that when the device is in operation, on the one hand, the lifting motor works with the transmission of the motor splines and spline shaft to achieve the lifting function, making the lifting drive efficiency more stable. In addition, the lifting is remotely controlled by a wireless transceiver module and a remote control key. On the other hand, the friction pads and brake discs on the brake calipers work together to achieve the braking protection function and improve the safety of operation. Attached Figure Description
