A jack is a lightweight lifting device that uses a steel lifting element as a working device to lift heavy objects within its travel through a top support or bottom support claw. Mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. Its structure is lightweight, sturdy, flexible and reliable, and can be carried and operated by one person.
working principle:
Jacks are divided into mechanical jacks and hydraulic jacks, each with different principles. In principle, the most basic principle on which hydraulic transmission is based is Pascal's law, which means that the pressure of the liquid is uniform everywhere. In this way, in a balanced system, the pressure applied on the smaller piston is relatively small, while the pressure applied on the larger piston is also relatively large, which can maintain the stillness of the liquid. So through the transfer of liquid, different pressures can be obtained at different ends, achieving the purpose of transformation. The commonly used hydraulic jack utilizes this principle to achieve force transmission. The screw jack uses a reciprocating lever to pull out the claw, which pushes the ratchet clearance to rotate. The small umbrella gear drives the large umbrella gear, causing the lifting screw to rotate, thereby enabling the lifting sleeve to lift or lower, achieving the function of lifting tension. However, it is not as simple as a hydraulic jack.
Function: Used for lifting, supporting, etc., when replacing car tires.

Structure of electric vehicle follow-up brake: It mainly includes components such as brake box, two brake shoes, crank, reset spring, adjusting parts, tension column, etc. Specifically, the working principle of the follow-up brake is to increase the rotation angle of the two brake shoes during braking through the setting of metal plates and reels, thereby increasing the maximum braking resistance. This structure achieves the adjustment of braking effect through two brake shoe blocks hinged on the hinge shaft fixed on the brake box, as well as adjusting components provided on the brake box on one side of the hinge shaft. In addition, the follow-up brake also has a lock that can lock the brake disc components, providing dust-proof and waterproof functions to ensure brake sensitivity
The window regulator motor is the power source of the window glass lifting system, responsible for driving the glass up and down. It is usually installed inside the car body or in the car door, connected to the window glass through steel wire ropes or guide rails, to achieve the control of the window lifting. The working principle of a motor is based on electromagnetic induction and changes in the direction of current. By changing the direction of current, the motor’s forward and reverse rotation can be controlled, thereby achieving the up or down movement of the car window. The start and stop of the motor are controlled by the switch inside the car, making it convenient for the driver to operate. In addition, in order to protect the motor, wire rope, and guide rail, a lubrication system is also installed in the system to provide lubricating oil for these components, reduce friction, and extend service life.
